Objectives: The aim is to investigate the influence of an active otitis media on the success rate of tympanoplasty in patients with a chronic otitis media (COM) and a tympanic membrane perforation. Databases Reviewed: PubMed, Embase and the Cochrane Library. Methods: The inclusion criteria were studies on closure rates of tympanoplasty performed in COM patients of any age with a tympanic membrane perforation caused by COM. The exclusion criteria were studies on patients undergoing concomitant mastoidectomy, ossicular chain reconstruction, tuboplasty, adenoidectomy, revision tympanoplasty, patients with perforations due to other conditions than COM, and letters to editors, commentaries, conference abstracts and case reports. The included articles were critically appraised using the QUIPS tool. Data on tympanic membrane closure rate were extracted, odds ratio (OR) and 95% confidence intervals (CI) of the closure rate with a wet versus a dry ear were calculated. Results: The search was performed on 1 February 2023. Of 4671 articles, 16 studies were included and critically appraised. Of these observational studies (nine prospective, seven retrospective), with a total of 1509 patients (dry ear group n = 1003; wet ear group n = 506), two studies stated a significant difference in success rate, one in favour of a dry ear and one in favour of a wet ear at time of surgery. All other studies did not show a statistically significant difference. Overall, the risk of bias was considered moderate to high. Conclusions: We found no significant prognostic value of having an active otitis media during tympanoplasty on tympanic membrane closure rates. Because the overall risk of bias was considered moderate to high, no strong conclusions can be made. To be able to answer this question with higher levels of evidence, high‐quality prospective or randomized studies are needed. [ABSTRACT FROM AUTHOR]

Objectives: Eustachian tube dysfunction (ETD) is a common disease associated with chronic otitis media. A standard diagnostic tool for ETD in patients with tympanic membrane perforation is still lacking. We developed and validated a new diagnostic model for ETD in patients with tympanic membrane perforation. Methods: A prospective study was conducted in patients who had tympanic membrane perforation from February to August 2023. We collected clinical characteristics and examination results including otoscopy, nasal endoscopy, tubomanometry, and 5-item Eustachian Tube Score (ETS-5). Univariate and multivariate logistic regression analysis was performed to determine the independent diagnostic factors. Based on this, the nomogram model was constructed. The discrimination and calibration of the nomogram were evaluated using the area under the curve (AUC), the C-index, the calibration curve, and the decision curve analysis (DCA). Results: A total of 40 participants were enrolled in the study. ETS-5 score and Eustachian tube opening mucosa inflammation in the nasopharynx were significant predictors in identifying ETD. Based on the above independent predictors, a diagnostic nomogram was successfully established. The sensitivity and specificity of the diagnostic model were 80.0% and 90.0%, respectively. The AUC and the C-index of the diagnostic model were both 0.901, which suggested that the model had a good discrimination power. The calibration curve indicated a good calibration degree of the model. DCA showed that the proposed model was useful for clinical practice. Conclusion: The nomogram model is effective and reliable in identifying ETD in patients with tympanic membrane perforation. [ABSTRACT FROM AUTHOR]

Objective: The objective of this study was to compare the outcomes of endoscopic cartilage myringoplasty (ECM) with or without plasma radiofrequency (RF) tuboplasty (PRT) for repairing chronic large perforation with Eustachian tube dysfunction (ETD). Materials and methods: Chronic large perforations with ETD were randomly divided into receiving ECM or ECM plus PRT. During the 24 months follow-up, the Eustachian tube score (ETS), Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7), ET inflammation scale, hearing results, and graft success rate of the patients were analyzed. Results: A total of 61 subjects were included in the study. Difference of ETS was significant before and after surgery in the ECM + PRT group (P <.05) but the ECM group was not (P >.05). Also, significant between-group difference was found regardless of post-24 months ETS and improvement value. Postoperative ETDQ-7 scores were significantly reduced compared with preoperative ETDQ-7 scores in both groups (P <.05), also, significant between-group difference was found regardless of post-24 months ETDQ-7 scores and improvement value. The graft success rate was 86.7% in the ECM group and 96.8% in the ECM + PRT group at postoperative 24 months (P >.05). In addition, although the ECM + PRT group showed a better air-bone gap improvement than the ECM group, the difference was not significant (13.01 ± 2.97 vs 10.92 ± 0.69 dB; P >.05). No PRT procedure-related serious adverse events were reported during the follow-up process. No patients developed atelectasis or otitis media with effusion in either group. Conclusion: ECM combined with low-temperature PRT did not affect the graft success rate but showed a better long-term improvement in ETS and ETDQ-7 than cartilage myringoplasty for the treatment of chronic perforation with ETD. In addition, although PRT showed a better hearing improvement, the difference was not significant between the 2 groups. [ABSTRACT FROM AUTHOR]

Objective: The objective of this study was to compare the postoperative infection and graft success rates, and the hearing improvement, after endoscopic cartilage underlay myringoplasty with versus without antibiotic ointment coating. Materials and methods: This was a retrospective case-control study. The clinical records of patients who underwent endoscopic cartilage underlay myringoplasty and who met the selection criteria were retrieved and divided based on middle ear packing status into groups with antibiotic ointment packing (AOP group) and with no antibiotic ointment packing (no-AOP group). The operation time, postoperative infection, graft success status, and hearing improvement were compared between the 2 groups. Results: Patients with 166 perforations constituted the AOP group, and patients with 141 perforations comprised the no-AOP group. At 3 months postoperatively, middle ear infections had occurred in 24 (14.5%) ears in the AOP group and 4 (2.8%) ears in the no-AOP group (P <.01). At 12 months postoperatively, the graft success rate was 81.3% in the AOP group and 97.9% in the no-AOP group (P <.01). No significant group differences were observed, preoperatively (P =.657) or postoperatively (P =.578), in the air-bone gap (ABG) values or mean ABG gains (P =.758). Conclusion: Middle ear packing without antibiotic ointment coating does not increase the postoperative infection rate or reduce the graft success rate after endoscopic cartilage underlay myringoplasty compared to antibiotic ointment coating. On the contrary, coating with antibiotic ointment increases the risk of postoperative infection given the complexity of middle ear manipulation. [ABSTRACT FROM AUTHOR]

Polymer piezoelectrics with high electromechanical energy conversion (HEEC) are very promising for flexible acoustoelectric devices. However, reducing thickness and improving ordered polarization and ferroelectricity while maintaining high mechanical strength pose enormous fabrication challenges for polymer piezoelectric membranes—additionally, noise management in the acoustoelectric conversion remains an open issue. Here, we present a hydro-levitation superspreading approach for fabricating polymer nanomembranes with ordered crystalline phases and sub-nanostructures on the water surface. The elastic piezoelectric nanomembrane (EPN) is only 335 nanometers thick and consists of a conductance-stable piezoelectric layer sandwiched between two elastic damping layers. Such an all-in-one EPN can reduce background noise with low autocorrelation in the environment, suppress spurious noise caused by poor circuit contact, and achieve bandpass filtering of acoustic signals at human voice frequencies. This nanomembrane holds promise in repairing the auditory system of patients with tympanic membrane perforation and in a wide range of other acoustoelectric conversion fields. Creating flexible acoustoelectric devices with ultrathin thickness, high elasticity, stable conductivity, and high electromechanical energy conversion capability poses a challenge. Zhang et al. present a liquid crystal mediated technique that creates an elastic piezoelectric nanomembrane with double noise reduction, offering promise for auditory system reconstruction and other acoustoelectric conversion applications.

Chronic tympanic membrane (TM) perforation is a tubotympanic disease caused by either traumatic injury or inflammation. A recent study demonstrated significant progress in promoting the regeneration of chronic TM perforations through the application of nanofibers with radially aligned nanostructures and controlled release of growth factors. However, radially aligned nanostructures with stem cell-stimulating factors have never been used. In this study, insulin-like growth factor binding factor 2 (IGFBP2)-incorporated radially aligned nanofibrous patches (IRA-NFPs) were developed and applied to regenerate chronic TM perforations. The IRA-NFPs were prepared by electrospinning 8 wt% polycaprolactone in trifluoroethanol and acetic acid (9:1). Random nanofibers (RFs) and aligned nanofibers (AFs) were successfully fabricated using a flat plate and a custom-designed circular collector, respectively. The presence of IGFBP2 was confirmed via Fourier transform infrared spectroscopy and the release of IGFBP2 was sustained for up to 20 days. In vitro studies revealed enhanced cellular proliferation and migration on AFs compared to RFs, and the incorporation of IGFBP2 further promoted these effects. Quantitative real-time PCR revealed mRNA downregulation, correlating with accelerated migration and increased cell confluency. In vivo studies showed IGFBP2-loaded RF and AF patches increased regeneration success rates by 1.59-fold and 2.23-fold, respectively, while also reducing healing time by 2.5-fold compared to the control. Furthermore, IGFBP2-incorporated AFs demonstrated superior efficacy in healing larger perforations with enhanced histological similarity to native TMs. This study, combining stem cell stimulating factors and aligned nanostructures, proposes a novel approach potentially replacing conventional surgical methods for chronic TM perforation regeneration. Chronic otitis media (COM) affects approximately 200 million people worldwide due to inflammation, inadequate blood supply, and lack of growth factors. Current surgical treatments have limitations like high costs and anesthetic risks. Recent research explored the use of nanofibers with radially aligned nanostructures and controlled release of growth factors to treat chronic tympanic membrane (TM) perforations. In this study, insulin-like growth factor binding protein 2 (IGFBP2)-incorporated radially aligned nanofibrous patches (IRA-NFPs) were developed and applied to regenerate chronic TM perforations. We assessed their properties and efficacy through in vitro and in vivo studies. IRA-NFPs showed promising healing capabilities with chronic TM perforation models. This innovative approach has the potential to improve COM management, reduce surgery costs, and enhance patient safety. [Display omitted] [ABSTRACT FROM AUTHOR]

Objectives: To study the predisposing factors, treatment, and complications of Aspergillus otitis externa. Methods: A retrospective analysis of patients diagnosed with Aspergillus otitis externa at the Department of Otorhinolaryngology, Helsinki University Hospital, between January 2010 and December 2018 was performed. Results: Of the 269 Aspergillus otitis externa (OE) patients, 96 developed otitis media (OM) and 7 developed mastoiditis. Antibiotic and steroid treatment and otological history were risk factors for Aspergillus OE. Systemic diseases and immunocompromising states were more common in mastoiditis patients. Repetitive ear cleaning and topical drugs are primary treatments, but systemic drugs and surgery were needed in resistant and invasive cases. Forty‐five novel tympanic membrane (TM) perforations were reported. A strong association between Aspergillus species and final infection types was found; A. niger was the dominant species in OM and in novel TM perforations, whereas A. flavus and A. fumigatus caused mastoiditis. Some of the TM perforations persisted despite treatment. Permanent hearing impairment was associated with OM and mastoiditis. Conclusion: As Aspergillus OE has the potential to cause acute and chronic complications, fungal OE should be suspected early on if the infection persists after conventional treatment. The identification of Aspergillus species could aid in spotting patients at risk for more severe disease and complications. Intensive local treatment is sufficient in most cases of OE and OM but effective topical antifungals are limited. Patients with Aspergillus OM and mastoiditis should be followed up for hearing impairment and permanent TM perforations after the infection resolves. Level of evidence: Level 4 (The Oxford 2011 Levels of Evidence). Aspergillus otitis externa may lead to a wide range of frequent and rare complications, including tympanic membrane perforations, otitis media, mastoiditis, permanent hearing loss, and cranial nerve palsies. Aspergillus niger causes most otitis media and tympanic membrane perforations, whereas A. flavus, A. fumigatus, and immunocompromising states are predispoding factors for mastoiditis. Careful local treatment is efficient in most cases but surgery and systemic antifungals are needed in profound infections. [ABSTRACT FROM AUTHOR]

The study was carried out on 50 patients with central perforation in tympanic membrane (dry & inactive stage). The study was done in the department of ENT, MIMS medical college, Nellimarla, Vizianagaram over a period of one year. The study was done on comparison between tympanoplasty procedure using temporalis fascia as graft versus cartilage composite graft. Precise history was taken from respective patients in detail and were examined clinically. Patients with dry perforation with good cochlear reserve, intact and mobile ossicular chain, functioning Eustachian tube were selected randomly for the operation. Tympanoplasty procedure using temporalis fascia as graft was done in 50% (n=25) patients and tympanoplasty procedure using cartilage composite graft was done in 50% (n=25) patients. In this study the age range of patients were from 13 to 50 years, the mean age was 26.62 years, the number of male and female was equal. Right sided disease was predominant in our study and the mean duration of symptom was 11.24 months. The mean pre-operative hearing loss (pure tone average by pure tone audiometry) was 37.84±4.65 dB and mean pre-operative airbone gap was 22.84±4.65 dB. Post-operative Mean air conduction was 23.48±5.54 dB among them 24.2 ±6.26 dB in the fascial group and 22.76±4.73 dB in the cartilage group. This result is not statistically significant. Post-operative mean air-bone gap was 13.84±5.94 dB among them 14.76±5.6 dB in fascial group and 12.92 ±6.23 dB in the cartilage group which is not significant stastistically. Successful graft take-up rate of 88.00% (n=44). The overall success rate among tympanoplasty using temporalis fascia graft(GROUP A) and tympanoplasty using composite cartilage graft (GROUP B) technique were 84.00% (n=21) and 92.00% (n=23) respectively. 12.00% (n=6) patients were marked as failure cases during postoperative follow up period. The overall failure rate among tympanoplasty using temporalis fascia graft (GROUPA) and tympanoplasty using composite cartilage graft (GROUP B) technique were 16.00% (n=4) and 8.00% (n=2) respectively. So the distribution of surgical outcome in terms of success rate or failure rate was statistically insignificant in the two study groups (p=0.384). So the distribution of surgical outcome in terms of success rate or failure rate cartilage composite graft gives a definitely better result than temporalis fascia graft. However, the two method did not differ significantly in terms of hearing improvement. [ABSTRACT FROM AUTHOR]

Aim: This study is aimed to compare the outcomes of the two techniques (endoscopic single flap tympanoplasty- ESFT versus endoscopic double flap tympanoplasty - EDFT) of endoscopic tympanoplasty for repairing large tympanic membrane (TM)perforations with limited anterior remnant. Methodology: In this randomised controlled trial, forty patients with large sized TM perforations were included and randomised in the ESFT and EDFT arms with twenty patients in each group. Both the groups underwent endoscopic tympanoplasty using temporalis fascia graft. The graft uptake rates and hearing results were compared. Results: Graft success rate was 85% (17/20 cases) in the ESFT group and 90%(18/20 cases) in the EDFT group. The ABG (air-bone gap) improvement median with interquartile range(IQR) was 5 dB (3.12 dB-10 dB) in the ESFT group and 8.75 dB (5dB-11.87 dB) in the EDFT group. The difference was not statistically significant. Conclusions: In our study, there was no statistically significant difference in the graft success rate or hearing gain in ESFT or EDFT group. Moreover, there was longer operative time and need for an extra incision while raising the anterior flap. This lack of statistically significant results in our study may be since the study has a very small sample size. Whether the same conclusion is reproducible needs to be further explored by a larger sized randomised controlled trial. [ABSTRACT FROM AUTHOR]

Middle ear aeration is a predictive indicator of myringoplasty's successful outcome and tympanometric ear canal volume is a novel investigation that can estimate the volume of middle ear cleft and mastoid air cells. Our aim of this study is to determine the role of tympanometric ear canal volume on myringoplasty outcome in Chronic Suppurative Otitis Media Patients. Prospective analysis involving 50 patients of CSOM was performed on patients undergoing myringoplasty from April 2022 to December 2023. Smokers, Patients with squamosal COM, Bilateral COM, Otitis Externa, and Revision surgery were excluded from the study. The successful outcome of surgery was defined as no tympanic membrane perforation on postoperative follow-up. Analysis was carried out using SPSS. V. 25 and P-value less than 0.05 was considered significant. A total of 50 patients were included in the study with a mean age of 24.4 ± 8.965 and male predominance. Overall graft uptake was 64%. Graft uptake had no significant statistical correlation with age, gender, type, location, or size of perforation. However, there is a significant effect of tympanometric ear canal volume of pathological ear and interaural tympanometric ear canal volume difference on graft uptake with p-values of 0.023 and 0.033 respectively. Tympanometric ear canal volume can predict middle ear aeration and the higher the interaural tympanometric canal difference more are the chances of successful graft uptake. [ABSTRACT FROM AUTHOR]

Children in foster care have complexity around medical decision-making because of their unique custody status. When medical decision-making is necessary for a child in foster care, what perspectives are important? What if opinions are not aligned? Who makes the final decision for consent? This Ethics Rounds focuses on a young child in foster care who has had repeated ear infections. Foster caregivers and family of origin are not in agreement on the treatment plan. Two experts, a foster care pediatrician and a child welfare professional, comment on the important considerations for the case, including involvement of legal representation and best interest representation in medical decision-making as well as the variability in child welfare response by state.

Purpose: This study aimed to assess the efficacy and safety of ballon dilation of the eustachian tube (BDET) in adult population suffering from Eustachian tube dysfunction (ETD). Methods: Following PRISMA criteria, a systematic review was conducted by searching PubMed, Cochrane, and Embase databases from January 2015 to March 2024. The primary outcomes included Eustachian Tube Score (ETS), tympanometry, and Valsalva maneuver. The quality of studies was assessed using the Quality in Prognostic Studies (QUIPS) instrument. Results: Overall, 11 studies were incorporated into the systematic review: two RCTs, three prospective investigations, and six retrospective studies. The balloon dilation in all investigations was performed using either Spiggle & Theis or Acclarent catheters for balloon dilation. There was heterogeneity across studies examining the effect of BDET on persistent ETD in terms of patient selection, period of follow-up, administration of conservative or surgical therapies, and use of assessment methods. Overall, the treatment yielded alleviation of symptoms, which either exhibited stability over time or demonstrated further improvement after an average duration of follow-up. Moreover, the incidence of complications was categorized as low and resolving spontaneously. The majority of the studies exhibited a high risk of bias related to confounding variables, and consequently, the overall risk of bias across most studies was considered high. Conclusion: The findings suggest BDET holds promise for ETD treatment, reducing symptom severity with minimal complications. Nonetheless, there is a need for improved studies that adhere to established indications, methodologies, and outcomes to establish a more robust body of evidence. [ABSTRACT FROM AUTHOR]

Tympanic membrane (TM) perforation is a serious ear discomfort that can cause hearing loss and make the middle ear vulnerable to infections. In this study, a unique TM patch is designed to mimic the structure of the natural eardrum for tissue engineering of TM perforations. Gelatin methacryloyl (GelMA)‐based TM patches are equipped with microneedles (MNs) to better adhere to the perforation site and developed using the digital light processing (DLP) based 3D printing technique. To impart biofunctionality to the 3D‐printed patches, their surfaces are coated with gentamicin (GEN) loaded poly(vinyl alcohol) (PVA) nanoparticles (NPs) using the Electrohydrodynamic Atomization (EHDA) method. The physicochemical characteristics, drug release behaviour, antimicrobial properties and biocompatibility of GelMA, PVA NP‐coated GelMA, and GEN@PVA NP‐coated GelMA patches are investigated. Morphological analyses confirmed that 3D‐printed GelMA patches are fabricated in desired sizes and geometries and successfully coated with NPs. In vitro antibacterial tests revealed that GEN@PVA NP‐coated GelMA patches have antibacterial activities against Staphylococcus aureus and Escherichia coli. Moreover, in vitro cell culture studies indicated that all GelMA‐based patches have no cytotoxic effect on L929 mouse fibroblast cells. Considering all, these specially designed biofunctional 3D‐printed GelMA patches can be an effective therapeutic approach for repairing TM perforations. [ABSTRACT FROM AUTHOR]

Background: The traditional approach for viewing middle ear structures during ear surgery is still the microscope, which provides both hands' flexibility and binocular vision. The requirement for a clear, direct vision of the working zone is its primary disadvantage. The procedure was modified for the microscope by using an end-aural approach, drilling the bone canal, and then moving the patient and surgeon. However, the microscope has successfully demonstrated that it is the preferred tool for stapedectomy. Objective: To compare endoscopic and microscopic interventions in stapes surgery regarding intraoperative and postoperative outcomes. Patients and methods: The review was a meta-analytic and systematic review that included randomized controlled trials (RCT), case series, and retrospective studies which studied the comparison of microscopic and endoscopic stapes surgery; 15 articles published between 2014 and 2020 were included in our study. Data sources: PubMed, Embase, and Cochrane Library were searched for studies published up to 2020. The inclusion criteria comprised randomized controlled trials, cohort studies, and case–control studies comparing microscopic and endoscopic stapes surgeries. Results: Our results showed that the injury to the chorda tympani nerve was significantly higher in the microscopic group versus the endoscopic group. And also, as regards the operative times, it was significantly longer in the microscopic group versus the endoscopic group. But there is no significant difference as regards pain, dizziness, perforation of the tympanic membrane, delayed conductive hearing and postoperative air–bone gap improvement, and taste disturbance between both groups. Conclusion: Technologically, safely, and promisingly, endoscopic stapes procedures are possible. All things considered, our research shows that both microscopic and endoscopic stapes surgery yields good audiological outcomes. A little amount of data, however, points to a decreased likelihood of chorda tympani injury and taste disturbance when using an endoscope. With comparable side effects to microscopic stapes surgery (pain, tympanic membrane perforation, taste disturbance, dizziness, and delayed conductive hearing), endoscopic stapes surgery seems like a feasible substitute. Endoscopic stapes surgery was found to need shorter operating times. In comparison to endoscopic groups, the postoperative air–bone gap increased considerably in the microscopic group. All of the studies consistently indicated better sight with the endoscope. This meta-analysis of the available data bolsters the application of endoscopic methods in stapes surgery.

Introduction: The objective of this study was to identify and clinically characterize patients treated in an Otoneurology Unit who experienced vestibular ototoxicity as a result of using aminoglycoside ear drops during outbreaks of superinfection in chronic otitis media. Material and Methods: An observational retrospective study was conducted, including patients with perforated eardrums who developed vestibular ototoxicity within the past 10 years following the application of topical ear aminoglycosides in a tertiary referral center. The study encompassed the assessment of the clinical presentation, treatment, quality of life, and evolution after treatment of the identified individuals. Results: During the study period, 6 patients, aged between 33 and 71 years, developed vestibular ototoxicity following the use of topical aminoglycoside drops due to infection flares in chronic otitis media. All cases involved the use of gentamicin. Two cases were unilateral, and 4 were unilateral. The onset of symptoms occurred within one to four weeks of using the drops, resulting in all patients experiencing instability without vertigo attacks. After discontinuing the drops and undergoing vestibular rehabilitation, 4 patients experienced sequelae, with 2 patients (both with bilateral vestibular hypofunction) suffering significant impairment in their quality of life. Conclusions: Vestibular ototoxicity due to the topical application of aminoglycosides during acute exacerbations of chronic otitis media is a rare occurrence. However, given its potential for severe consequences and the fact that we are still encountering patients with this condition, healthcare professionals should explore alternative antibacterial agents that offer similar efficacy.

Benign dendritic melanocytic proliferation is usually observed in the skin. We report an extremely rare case of a melanocytic lesion in the middle ear mucosa. Only 3 cases of melanocytic lesions in the middle ear have been reported. Our report is the only one that describes an adult with a melanocytic lesion in the middle ear that extended to the inner ear and nasopharyngeal mucosa. A 23-year-old female presented with profound sensory neural hearing loss and recurrent discharge from the right ear. Examination revealed a blue right tympanic membrane with a small perforation. Computed tomography scans and magnetic resonance imaging were performed. After surgical exploration and histopathological examination, the patient was found to have a benign melanocytic lesion in the right middle ear. Melanocytic lesions are commonly found in the skin. There are no previous reports have described adult patients with melanocytic lesions in the middle ear that extend to the inner ear and nasopharynx, which cause profound hearing loss with recurrent ear discharge. These patients require regular follow-up to assess the progression of the lesion and to watch for any malignant behavior. [ABSTRACT FROM AUTHOR]

Introduction: This study aimed to investigate the impact of central and marginal tympanic membrane perforations (TMP) on wideband absorbance (WBA) and compare it with normal ears. Material and methods: Three groups of individuals, aged 18 to 50 years: Group I with central TMP (n = 65), Group II with marginal TMP (n = 13), and Group III with normal middle ears (n = 20) were considered. WBA measurements were performed at peak and ambient pressure conditions across frequencies. Results: Significant differences in WBA were observed between the groups with central and marginal TMP and the normal ear group across all frequencies. Central TMP exhibited decreased absorbance at low frequencies and increased absorbance at high frequencies, peaking at 5000 Hz. Marginal TMP showed peaks at 600, 4000, and 6000 Hz with decreased absorbance at 2000 Hz. Central TMP exhibited lower absorbance than marginal TMP at lower frequencies, while marginal TMP showed decreased absorbance at mid and high frequencies. Conclusions: These findings highlight the role of WBA in differentiating normal ears from those with TMP. Understanding TM vibration patterns and frequency-dependent variations in absorbance enhances diagnostic accuracy and clinical management. [ABSTRACT FROM AUTHOR]

Purpose: Retrospective evaluation of bilateral same-day myringoplasty outcomes. Methods: Patients who underwent bilateral same-day myringoplasty from 2005 to 2019. Results: Thirty-eight patients underwent bilateral myringoplasty. Mean age was 44.5 years and 55.3% patients were male. Tragal perichondrium-cartilage composite graft was the most frequently used graft material (82.9%). Perforation closure was achieved in 78.9%. Postoperative Pure Tone Average and Air–Bone Gap decreased significantly (p < 0.05), except for the Air–Bone Gap of the right ear (p = 0.058). The complications were cholesteatoma (1.3%), otorrhea (6.6%) and tympanic membrane retraction (1.3%). Conclusions: Bilateral same-day myringoplasty is a feasible procedure in selected patients. Good anatomic and functional outcomes, as well as a low rate of complications, are achieved with this procedure, improving patient comfort and allowing for a reduction in operation time and costs.

Background: Biomaterials and surgical techniques for reconstructive tympanic membrane surgery are under development. Objectives: The objective of this study is to analyze the functional and surgical outcomes of a novel fascia with cartilage reinforcement technique for anterior tympanic membrane perforation in tympanoplasty. Methods: Records of 198 patients with anterior tympanic membrane perforation who underwent tympanoplasty between August 2018 and March 2021 were prospectively reviewed. Patients with dry anterior quadrant perforations of the tympanic membrane were included and underwent tympanoplasty using two methods: Type 1 tympanoplasty with temporalis fascia only, and tympanoplasty with fascia and cartilage reinforcement. Postoperative functional and surgical outcomes were analyzed. Results: Comparing the pre-operative and post-operative air conduction levels and air-bone gaps showed significant improvement in both groups (P < 0.001). Additionally, no significant difference was observed between air-bone gap closure (P = 0.316) and increase in air conduction levels (P = 0.222) according to graft type. Conclusions: Both temporalis muscle fascia and temporalis muscle fascia with cartilage reinforcement revealed satisfactory functional and surgical outcomes. Furthermore, the novel combined cartilage-fascia technique had a comparable graft take rate and hearing results in anterior perforations, with no significant change in tympanic membrane vibratory properties.

Abstract Background Myringoplasty is one of the most common surgeries performed in otology centers, with many factors influencing the success rate, including the size and site of perforation, function of the Eustachian tube, revision surgery, and expertise of the surgeons. It is well established that the perforation closure rate is lower when performed by trainee surgeons than by senior otologists. Myringoplasty performed by trainees tends to pose more iatrogenic trauma to middle ear mucosa, less gentle manipulation of ossicles, and prolonged operation time compared with operations performed by experienced surgeons, all of which might produce more damage to middle ear structures and consequently negatively affect the closure rate of TM and audiological outcome. This study aimed to assess the audiological outcomes of successfully closed perforation myringoplasty performed by a trainee under supervision. Methods The study design was an analytic cross-sectional study of 35 patients aged between 6 and 62 years diagnosed with safe TM perforation. All patients had two audiograms, one before surgery and the other 3 months after surgery. The exclusion criteria included any case with cholesteatoma, tumor, tympanosclerosis, or ossicular erosion/fixation because this study aimed to study the sole effect of closing TM perforation without any other confounding factor. Results The results indicate a mean hearing improvement of 12.25 dB of ABG and 10.6 dB of AC thresholds at the four frequencies of 500, 1000, 2000, and 4000 Hz. The mean of the residual ABGs at the four frequencies is 14.2 dB. There were no correlations between the amount of air conduction threshold improvement and age, gender, side of the affected ear, area of perforation, or duration of disease (p > 0.05 for all tests). Conclusion Although the rate of perforation closure in myringoplasties performed by trainees is lower than that of experienced surgeons, the audiological outcomes of myringoplasties performed by trainees under supervision were acceptable; however, further research is recommended.

Background Various graft materials have been used for closure of small tympanic membrane perforations with varying success rates. This study was done to compare the success rates of endoscopic fat plug myringoplasty (EFPM) and chemical cauterization for managing small TM perforations. Methodology This was a prospective study conducted in ENT Department of a teaching hospital of western Gujarat from November 2020 to December 2022. 50 patients with small central dry perforation were randomly divided into 2 groups. 25 patients in Group A underwent endoscopic fat plug myringoplasty (EFPM) and 25 in Group B underwent trichloroacetic acid (TCA) application (chemical cauterization). At the end of 3 months (last follow-up) the perforation closure rates and hearing improvement were compared between the two groups. Results Out of 50 participants, 20 (40%) were males and 30 (60%) females. 36% participants belonged to 31-40 years of age group. The perforation closure with EFPM was significantly higher than chemical cauterization (92% vs 64%, p=0.0168) measured at 3 months follow-up. Similarly, the post operative hearing improvement was significantly better with EFPM that with chemical cauterization (p=0.0168). Conclusions EFPM is an effective method for managing small central tympanic membrane perforations. It is a day-care procedure and success rate is equal or even better than other modalities of managing small TM perforations. This method should be used more often.

All patients had two audiograms, one before surgery and the other 3 months after surgery. The exclusion criteria included any case with cholesteatoma, tumor, tympanosclerosis, or ossicular erosion/fixation because this study aimed to study the sole effect of closing TM perforation without any other confounding factor. Results: The results indicate a mean hearing improvement of 12.25 dB of ABG and 10.6 dB of AC thresholds at the four frequencies of 500, 1000, 2000, and 4000 Hz. The mean of the residual ABGs at the four frequencies is 14.2 dB. There were no correlations between the amount of air conduction threshold improvement and age, gender, side of the affected ear, area of perforation, or duration of disease (p > 0.05 for all tests). Conclusion: Although the rate of perforation closure in myringoplasties performed by trainees is lower than that of experienced surgeons, the audiological outcomes of myringoplasties performed by trainees under supervision were acceptable; however, further research is recommended.

To assess the effectiveness of the autologous plasma-rich fibrin plug technique for repairing small tympanic membrane perforations. Platelet rich fibrin (PRF) is also called second generation platelet rich plasma due to its high amount of growth factors which could be used in tympanic perforation closure. Being autologous, it is readily available with no immunogenic reactions. PRF membrane has a strong elastin fibrin structure containing growth factors and hence can be considered as an ideal sealing material or an adjuvant to the graft in repairing tympanic membrane perforations. Ours is a prospective study. A total of 52 patients with dry small tympanic membrane perforation were included in the study. In this technique, 10 ml of blood is withdrawn from the patient, processed in a centrifuge machine, and platelet-rich fibrin (PRF) is separated from the mixture for use in the repair of small tympanic membrane defects. Out of the 52 patients, 42 experienced successful repair (full closure) of the tympanic membrane. The mean time of closure of the perforation was around 2 weeks. However, five of them encountered failure. Although the size of the perforation decreased compared to the preoperative size. Additionally, two patients developed granulations on the tympanic membrane. No major side effects were noted. Autologous PRF is a product derived from whole blood through the process of centrifugation. It is safe and effective in promoting the natural process of wound healing by incorporating a high concentration of platelet-derived growth factors as well as fibrin into the graft mixture. This facilitates the rapid healing of tympanic membrane perforation. [ABSTRACT FROM AUTHOR]

Objective: To assess differences in otorrhea, tympanic membrane perforation, and time to extrusion in children receiving one of four commonly used, short‐term ventilation tubes for the first time. Methods: Retrospective chart review of 2 years of postoperative follow‐up to analyze patient outcomes after insertion of either a Paparella type‐I Activent, Armstrong Beveled, Modified Armstrong, or Armstrong Microgel ventilation tube. Incidence of complications was determined by reviewing provider notes. Adjusted multivariate logistic regression models were used to determine odds ratios of complications among the four tube types. Results: A total of 387 patients were reviewed. The mean age was 2.4 years and 35.9% were female. Armstrong beveled tubes had the highest odds of otorrhea. Paparella type‐I tube had the shortest time to extrusion of about 9 months, while Armstrong Beveled had the longest, at almost 19 months. When evaluating episodes of otorrhea each child experienced on average, per month, Armstrong beveled tubes had the highest monthly rate of otorrhea and Paparella type‐I the least. No significant differences were found regarding tympanic membrane perforation. Conclusions: This retrospective chart review showed that no tube was clinically superior across all complications. The findings from this study may give otolaryngologists an opportunity to consider choosing a specific type of tube according to the clinical situation. The large variations in extrusion times should be considered in terms of patient age, seasonality, and desired duration of tube placement. Level of Evidence: 4. Differences in otorrhea, tube blockage, tympanic membrane perforation, and time to extrusion were evaluated among children receiving one of four commonly used short‐term ventilation tubes: Paparella type‐I Activent, Armstrong Beveled, Modified Armstrong, and Armstrong Microgel. The major difference between tubes was time to extrusion and none was clinically superior in terms of complications. The large differences in extrusion times should be considered in terms of patient age, seasonality and desired duration of tube placement, and may give otolaryngologists an opportunity to consider choosing a specific tube according to the clinical situation.

Background: Most tympanic membrane (TM) perforations heal spontaneously, but 10%–20% remain chronic and might lead to impaired hearing and recurrent middle ear infections. Alpha1‐antitrypsin (AAT) is a circulating tissue‐protective protein that is elevated under inflammatory conditions and is currently indicated for genetic AAT deficiency. Recently, AAT has been shown to promote tissue remodeling and inflammatory resolution. Objective: This study aimed to examine the effects of local clinical‐grade AAT treatment on tissue repair in a mouse model of acute traumatic TM perforation. Methods: Wild‐type mice underwent unilateral TM perforation and were either left untreated or treated locally with human AAT (9 × 10−3 mL at 20 mg/mL on days 0, 1, and 2; n = 15/group). The perforations were evaluated macroscopically on a serial basis. Mice were sacrificed on various days post‐injury, and TMs were excised for gene analysis by RT‐PCR. Results: There were no adverse reactions in hAAT‐treated ears throughout the study period. Compared with untreated animals, TM closure occurred earlier in the treated group (days until full closure, median: 4 and 9, respectively). According to gene expression analysis, VEGF, TGFβ, and collagen‐5A1 were induced earlier in AAT‐treated mice (day 4–5 compared with day 9). Additionally, IL‐10 expression levels were higher and IL‐6 levels were lower in treated versus untreated mice. Conclusion: A local tissue environment rich in AAT promotes early tissue repair in a perforated TM model both macroscopically and molecularly. Studies are underway to examine TM functionality and recombinant AAT formulations for micro‐dosing in the format of a single local application.

Objective: Endoscopic ear surgery is no longer a promising technique, but a well‐established one. This study aims to compare endoscopic and microscopic tympanoplasty based on current literature evidence, in terms of their efficacy and safety characteristics. Data Sources: We conducted a systematic literature search of four medical databases (Pubmed, Cochrane Library, Scopus, ClinicalTrials.gov), focusing on randomized controlled or observational studies comparing microscopic to endoscopic tympanoplasty. Review Methods: Data related to the efficacy and safety of each technique were extracted. Outcome data were summarized using pooled mean differences or pooled odds ratio along with their 95% confidence intervals. The risk of bias was estimated, by using the ROBINS‐I and RoB‐II assessment tools, while the overall quality of evidence was evaluated according to the GRADE working group. Results: Thirty‐three studies, with 2646 patients in total, were included in the meta‐analysis. Success rate was evaluated by estimating tympanic graft failure (pooled mean difference:−0.23; 95% CI: −0.61, 0.14, I2 = 33.42%), and air‐bone gap improvement (pooled mean difference:−0.05; 95% CI:−0.23, 0.13, I2 = 52.69%), resulting in comparable outcomes for the two techniques. A statistically significant difference favoring the endoscopic technique was detected regarding postoperative wound infection (OR: −1.72; 95% CI: −3.39, −0.04, I2 = 0%), dysgeusia (OR: −1.47; 95% CI: −2.47, −0.47, I2 = 0%), otitis externa development (OR: −1.96; 95% CI: −3.23, −0.69, I2 = 0%), auricular numbness (OR: −2.56; 95% CI: −3.93, −1.19, I2 = 0%), as well as surgical duration (OR: −1.86; 95% CI: −2.70, −1.02, I2 = 43.95%), when compared to the postauricular microscopic approach. Conclusion: Endoscopic tympanoplasty is an innovative alternative to the microscopic technique, resulting in commensurate outcomes regarding success rate. Furthermore, it offers superior results concerning postoperative complications, while it presents a significant reduction in the duration of surgery, mainly when it is compared to the postauricular microscopic approach.

Background: There is a need for a simpler and accessible intervention to heal tympanic membrane perforations than myringoplasty that is todaýs golden standard. Experimental studies have identified plasminogen as a promising agent for medical treatment of chronic tympanic membrane perforation. Aims/Objectives: This was a phase 1, prospective, randomized, placebo-controlled study with the main objective to evaluate the safety of injecting plasminogen in the vicinity of the tympanic membrane in subjects with chronic tympanic membrane perforation. Material and Methods: Adults diagnosed with a dry chronic tympanic membrane perforation were recruited for an injection schedule with Human plasminogen 10. Adverse events, audiometry, VAS fluctuations and size of perforation, were monitored throughout the length of the study. Results: It was possible to perform the injections according to schedule in all subjects. None of the subjects experienced any severe adverse events. Most common adverse event was ear pain. No signs of ototoxicity were reported. Conclusions and Significance: This pilot study suggests that plasminogen injections close to the tympanic membrane as treatment for chronic tympanic membrane injections are safe and feasible, encouraging further dose-escalating studies.

BACKGROUND: This study aimed to compare total endoscopic ear surgery (TEES) and microscopic postauricular canal-wall-down tympanomastoidectomy (CWD) in cholesteatoma surgery in our clinic. METHODS: This study included 59 patients, of whom 30 and 29 were operated on with CWD in 2016-2018 and TEES in 2019-2021, respectively and compared regarding intraoperative findings, hearing outcomes, long-term outcomes, and recidivism rates between groups. This study excluded patients in stage IV according to the European Academy of Otology and Neurotology/Japan Otological Society Staging System on Middle Ear Cholesteatoma, aged < 18, with congenital cholesteatoma, who underwent revision surgery. RESULTS: Two patients in the TEES group had recidivism (6.9%), with recurrent disease observed in both patients and residual disease in none, whereas 3 patients in the CWD group had recidivism (10%), including recurrent disease in 2 and residual disease in 1 patient. Tympanic membrane perforation occurred in 2 (6.9%) and 1 (3.3%) patients in the TEES and CWD groups, respectively. The 2 groups revealed no significant difference in terms of recidivism and perforation rates (P = 1.000, P = .612). The CWD group had a longer mean operation time (225.54 ± 47.86 minutes) than the TEES group (160.55 ± 24.98 minutes) (P < .001). The 2 groups demonstrated no significant difference regarding pre- and postoperative air--bone gap (ABG) and ABG gain (P = .105, P = .329, P = .82, respectively). CONCLUSION: Total endoscopic ear surgery provides similar results in terms of hearing, recidivism, and long-term outcomes with the microscopic CWD approach. However, the CWD approach is still important, especially in patients in advanced stages. [ABSTRACT FROM AUTHOR]

Objectives: We evaluated the closure rate after fat-graft myringoplasty (FGM) of perforations differing in size and location. We explored whether patient's factors and the FGM surgical technique influenced surgical outcomes. Methods: We retrospectively studied patients with tympanic membrane perforations who underwent FGM from March 2015 to March 2019. All procedures were performed by a single senior surgeon at our tertiary hospital. The patients who followed-up for at least 6 months after surgery were enrolled. We recorded hypertension and diabetes status, age, any prior ear surgery, any calcific plaques adjacent to the perforation, and perforation size and location. Results: A total of 150 patients were enrolled. Our success rate of FGM was 90%. Hypertension, diabetes, prior ear surgery history, and eardrum calcific plaques did not affect the surgical outcomes. There was no statistical difference in the surgical success rate according to the size (< 50%) or location of perforation. The closure rate was 97.2% in patients aged 1660 and 87.5% in patients aged > 60, respectively. However, FGM was successful in only two of six children (33.3%) aged ≤ 15 years, thus significantly less than in the other groups. Conclusion: FGM is a fast, safe, and efficient method for repairing tympanic membrane perforation. The surgical outcome is not significantly affected by underlying disease, perforation size or location, or by the condition of the tympanic membrane or older age. However, it may be poor in children with dysfunctional Eustachian tube. [ABSTRACT FROM AUTHOR]

This article compares two types of external ear canal packing options, Spongostan and Silastic, for endoscopic ear surgery. The study found that there was no statistically significant difference in post-operative healing outcomes between the two dressings. Both dressings were considered viable options for endoscopic ear surgery. The study aimed to fill a gap in the literature regarding packing options for this type of surgery. However, the study has limitations and further research is needed to determine the optimal timing of leaving the Spongostan dressing in place. [Extracted from the article]

Introduction: Fat tympanoplasty is repair of small dry tympanic membrane perforations using fat as graft material. It is a simple office procedure with minimal morbidity and manipulation of the middle ear. Materials and Methods: The present study was a prospective review of 60 patients who underwent fat tympanoplasty over the period of 15 months. In all the patients fat was harvested from ear lobule. Results: Patients were kept on follow up for 3 months and evaluated for graft uptake and hearing gain. 86.66% closure rate of tympanic membrane defect was achieved. Postoperative air conduction was 29.6 ± 5.3 while air bone gap was 13.2 ± 6.1. Conclusion: The study concludes that fat plug myringoplasty is a simple, quick, less invasive method to repair small tympanic membrane defects. [ABSTRACT FROM AUTHOR]

The tympanic membrane forms a barrier between the external auditory canal and the middle ear. In the inactive mucosal type of chronic otitis media, there is a perforation in the tympanic membrane which is surgically managed by Myringoplasty. Estrogen as a growth factor has been shown to have a mitogenic effect on keratinocytes thus hastening the rate of epithelialization following injury. This property of estrogen is being studied in this study for its role in the outcomes of myringoplasty. This study was carried out from January 2021 to December 2022 in the Department of Otorhinolaryngology, of a tertiary teaching hospital in North India. Patients were assessed by history, examination, otoscopy, Audiometry, and oto-endoscopy. A total of 88 patients were taken out of which 44 patients underwent myringoplasty in which topical estrogen (estradiol valerate solution) was used, and the remaining 44 patients were taken as controls. Patients were then assessed post-operatively based on Audiometry results and graft uptake status. In the estrogen group successful Graft uptake was in seen 40 (90.9%) patients and failed in 4 (9.1%), while in the control group, it was successful in 37 (84.1%) patients and failed in 7 (15.9%), statistically there was no significant difference between two groups in terms of graft uptake (p value = 0.334). Post-operatively, in the estrogen group, the mean change in Air Conduction (AC) was 15.5 dB, the change in the air-bone gap (ABG) was 11.5 dB and for Bone Conduction (BC) it was 3.2 dB. However, in the control group mean post-operative changes in Air Conduction, Air-Bone Gap, and Bone Conduction were 12 dB, 10.7 dB, and 0.8 dB respectively. Statistically, there was a significant difference in postoperative changes in AC (p value = 0.011) and BC (p value = 0.009) between the two groups. There was no significant difference in post-operative changes in Air-Bone Gap (p value = 0.571). Topical Estrogen (Estradiol valerate) solution is cost-effective, with enriched growth factors that accelerate tympanic membrane perforation closure following myringoplasty and resulted in significant improvement in hearing thresholds both for Air Conduction and Bone Conduction.

Aims: To study the outcome of cartilage tympanoplasty type I in patients with medium and large perforations using 0.5 mm sliced conchal cartilage reinforced with temporalis fascia grafts with 5 years follow-up. Study Design: Retrospective clinical study. Patients and Method: 120 patients with dry tympanic membrane perforation medium and large size and intact ossicular chain, and with no history of previous ear surgery were selected. An underlay type one tympanoplasty, using 0.5 mm sliced conchal cartilage reinforced with temporalis fascia, was performed during 2018-19. A successful anatomical outcome was considered to comprise full, intact healing of the graft without perforation these patients were evaluated for at least 5 years post-operatively till 2023. Results: In this study graft uptake rate was 95.33% for medium size and 93.66% for large perforations at 3 months and after 5 years of follow-up 92.77% medium size and large size perforations were 89.67.66% (P < 0.001). Residual perforations were there in about 7.29% in medium and 10.33% in large size perfrations. Conclusion: Sliced conchal cartilage reinforced with temporalis fascia is a reliable technique for tympanoplasty, with improved graft uptake results in medium and large perforations in the long-term, also the residual perforations is significantly lower.

Purpose: To compare the audiological outcomes, tympanic membrane (TM) healing rates and complication rates in patients undergoing endoscopic underlay and over–under tympanoplasty type I (TTI). Methods: The study includes 95 patients who underwent endoscopic TTI in the period between 2018 and 2023: 56% of the patients had the underlay technique and 41% had the over–under technique. Data regarding pre- and postoperative hearing, perforation characteristics, surgical procedures, graft types and complications were retrospectively analyzed. Audiometrical assessment included air conduction (AC) and bone conduction (BC) pure tone averages (PTA) and air–bone gap (ABG), pre- and postoperatively. Results: Both underlay and over–under techniques significant improved AC PTA, with a mean ABG improvements of 5.9 dB and 7.2 dB, respectively. There was no significant difference in BC PTA between pre- and post-operative, indicating no inner ear damage in both techniques. The over–under technique showed a significantly higher TM closure rate (94.4%) compared to the underlay technique (80.6%). Complications were rare, with only one case of TM lateralization requiring revision surgery. Conclusions: Endoscopic TTI is an effective treatment in improving auditory function in chronic middle ear diseases. In our cohort, the detachment of the umbo does not negatively influence the postoperative hearing results and does not increase rate of complications. Moreover, the over–under technique demonstrates superior TM closure rates, making it a valuable option for specific cases. However, future prospective studies with larger sample sizes and longer term follow-up are needed to validate these findings and provide more comprehensive insights. [ABSTRACT FROM AUTHOR]

Cholesteatoma secondary to tympanic perforation, known as "secondary acquired cholesteatoma" may progress slower than a retraction pocket cholesteatoma, with less bone destruction and fewer intracranial complications. However, complete surgical removal remains difficult because the pathological epithelium on the marginal side of the extension is not covered by the subepithelial layer of the cholesteatoma matrix, making the boundary with the middle ear mucosa difficult to identify. Therefore, considering the pathophysiology of secondary acquired cholesteatoma, suitable preoperative evaluation and surgical techniques are required. In this study, we aimed to evaluate (i) the extension of secondary acquired cholesteatoma according to the size and location of tympanic membrane perforation; and (ii) the microscopic surgical outcomes, including the rate of residual cholesteatoma, requirement for specialized surgical management, and changes in hearing. This retrospective study included data of cases with secondary acquired cholesteatoma (n = 66; 66 ears of 64 patients, 2 patients had bilateral ear involvement), including those who underwent a staged operation (n = 25). The perforation level of the tympanic membrane was associated with the cholesteatoma extension. When the cholesteatoma extended around the stapes, staged operation was chosen. Six cases of spontaneous resolution of stapes lesions at the time of staged surgery were observed. A significant postoperative improvement in hearing was observed; however, five cases experienced sensorineural hearing loss. Surgery, including staged surgery of the stapes lesions, along with careful observation of the perforation, is required in secondary acquired cholesteatoma. For lesions that are visible yet challenging to remove, it is imperative to exercise prudent judgment, taking into account the possibility of spontaneous resolution. [ABSTRACT FROM AUTHOR]

Abstract Objectives To study the predisposing factors, treatment, and complications of Aspergillus otitis externa. Methods A retrospective analysis of patients diagnosed with Aspergillus otitis externa at the Department of Otorhinolaryngology, Helsinki University Hospital, between January 2010 and December 2018 was performed. Results Of the 269 Aspergillus otitis externa (OE) patients, 96 developed otitis media (OM) and 7 developed mastoiditis. Antibiotic and steroid treatment and otological history were risk factors for Aspergillus OE. Systemic diseases and immunocompromising states were more common in mastoiditis patients. Repetitive ear cleaning and topical drugs are primary treatments, but systemic drugs and surgery were needed in resistant and invasive cases. Forty‐five novel tympanic membrane (TM) perforations were reported. A strong association between Aspergillus species and final infection types was found; A. niger was the dominant species in OM and in novel TM perforations, whereas A. flavus and A. fumigatus caused mastoiditis. Some of the TM perforations persisted despite treatment. Permanent hearing impairment was associated with OM and mastoiditis. Conclusion As Aspergillus OE has the potential to cause acute and chronic complications, fungal OE should be suspected early on if the infection persists after conventional treatment. The identification of Aspergillus species could aid in spotting patients at risk for more severe disease and complications. Intensive local treatment is sufficient in most cases of OE and OM but effective topical antifungals are limited. Patients with Aspergillus OM and mastoiditis should be followed up for hearing impairment and permanent TM perforations after the infection resolves.

The tympanic membrane (TM) is constantly in a state of vibrating. However, there is currently a lack of drug-delivery scaffolds suitable for the dynamic environment of TM perforation. In this study, a mechano-responsive tough hydrogel was developed. It consists of basic fibroblast growth factor (bFGF)-loaded sodium alginate (SA) microspheres, polysulfobetaine methacrylate (polySBMA), and gelatin methacrylate (GelMA). This hydrogel was designed to serve as a TM scaffold to promote perforation healing under dynamic conditions. bFGF was encapsulated in SA microspheres, which were then incorporated into polySBMA-GelMA hydrogels through photo-initiated free radical polymerization. The mechanical properties, tissue adhesiveness, swelling properties, and degradation of the hydrogels were evaluated before and after microsphere incorporation. It was observed that incorporating bFGF-loaded SA microspheres did not significantly impact the adhesion and degradation mechanisms of the hydrogel. The compressive strength and tensile strength of the microsphere-incorporated hydrogel were up to 6.6 MPa and 64.1 kPa, respectively, suitable for a TM scaffold. The release behavior of bFGF from the hydrogel could be controlled by vibration stimulation without significantly affecting the hydrogel's mechanical properties, indicating a mechano-responsive nature of the hydrogel. The in vitro cytotoxicity assay demonstrated that the hydrogels showed no cytotoxic effects. Moreover, cell culture assays demonstrated that vibration stimulation could enhance the release of bFGF, significantly promoting cell proliferation and migration. The results demonstrate the significant potential of the mechano-responsive hydrogel as a scaffold for repairing TM perforations.
