Background: Chronic suppurative otitis media (CSOM) is a major health issue in developing countries causing persistent problem and may lead to life-threatening complications. This major health issue and its complications can be best avoided by early and effective treatment. Aims and Objectives: The aim is to compare the outcome in terms of hearing improvement following canal wall up and canal wall down mastoid surgery. Materials and Methods: This prospective study was conducted in Otorhinolaryngology Department of a Burdwan Medical College and Hospital, Burdwan, a tertiary care hospital in Burdwan from April 2019 to August 2020 and 50 clinically diagnosed cases of COM (Squamous type) were included in this study after through history taking and meticulous clinical examination. Patients were divided in two Groups (Group-A and Group-B) with 25 patients in each group randomly and Group-A patients undergone canal wall up mastoidectomy and Group-B patients undergone canal wall down mastoidectomy (CWDM). Now, before performing surgery, a pre-operative pure tone audiometry was performed for each of the patients and a follow-up pure tone audiometry was done again, 2-month post-operative period. These results were compared to assess the degree of hearing improvement in the two different operative procedures, namely, canal wall up and CWDM. Results: In Group-A, the mean hearing gain (mean±SD) of patients was 12.5700±0.9856. In Group-B, the mean hearing gain (mean±SD) of patients was 8.4200±5.0051. Difference of mean hearing gain with both groups was statistically significant (P=0.0002). Chi-square value: 0.1678; P=0.9195. Conclusion: Hearing gain was more with canal wall up compared to CWDM in CSOM which was statistically significant.

Abstract Background Head injury most commonly occur following road traffic accidents. Often hearing loss and other otological injuries are missed in view of serious head injury or other visible bodily injuries, leading to delayed recognition of problems. There is a need for early clinical and radiological indicators which can predict adverse outcome. Early diagnosis of otological injury during initial evaluation of the head injury has given some clues regarding the severity of hearing outcomes and such correlation has been attempted in this study. Two-year cross-sectional study involving head injury patients with radiological evidence of temporal bone fracture were assessed for hearing impairment. Results Thirty-seven patients who satisfied the inclusion criteria were assessed. Fifty-one percent patients had conductive hearing loss. 35.14% of the patients had involvement of mastoid, external auditory canal, and middle ear involvement. A weakly positive correlation was noted between otic capsule sparing fracture and hearing loss. (R value + 0.2064). Conclusion Weak correlation was observed between temporal bone sub-site classification and severity of hearing loss in otic capsule sparing temporal bone fractures.

Abstract Introduction The aim of this study is to explore the potential factors in hearing outcomes and verify the role of oxidant‐antioxidant equilibrium on the prognosis of sudden sensorineural hearing loss (SSNHL) treated with hyperbaric oxygen therapy (HBOT). Methods Ninety‐two patients who were diagnosed with SSNHL between January 2018 and December 2019 in our hearing clinic center were included in this study. All patients were treated with intravenous dexamethasone, and 72 cases were treated with additional HBOT for 10 consecutive days. Peripheral blood was collected prior to any treatment to determine the blood cell count and hemoglobin (HGB), hematocrit (HCT), and superoxide dismutase (SOD) levels. Pure tone audiometry was measured before and after treatment. Complete and overall recovery rate was evaluated. Multivariate logistic analysis was used to identify prognostic factors. Results The rate of overall recovery was significantly higher in the patient with combined therapy compared to patients treated with steroids only (51.4% vs 25.0%, p = .036). The levels of HGB, HCT, and SOD were much higher in the patients with better hearing outcomes (p = .027, .033, and .011, respectively). Multivariate logistic analysis demonstrated that patients with higher initial hearing thresholds, or hearing loss at overall frequency, were more prone to have poor hearing gains after HBOT. Conclusion HBOT is effective as an early adjuvant therapy for SSNHL. Hearing loss at low frequency, low initial hearing thresholds, as well as high HBG, HCT, and SOD levels are positive prognostic factors for SSNHL patients treated with HBOT.

Abstract Objective Evaluation of the self‐perceived hearing impairment and performance after cochlear implantation in patients with definite Menière's disease (MD). Patients and Methods Seventeen unilaterally or bilaterally profoundly hearing‐impaired patients suffering from MD who received a cochlear implantat (CI) were eligible for inclusion in this study. Their self‐perceived hearing impairment using the short Speech Spatial and Qualities of Hearing Scale (SSQ12) as well as their performance in speech perception (German language Freiburger mono‐ and multisyllable test, Oldenburger sentence test) were compared with a best‐matched control group of non‐MD patients up to 24 months of follow‐up. Results MD patients improved significantly in perception of monosyllables presented at 65 dBSPL, from preoperatively best aided 18.2% [2.4, 34.0] to 51.7% [39.4, 63.9] 1 year after cochlear implantation (mean [95% confidence interval]). Their performance approached the matched controls with 63.2% [55.7, 70.8]. Monosyllables presented at a lower intensity of 55 dBSPL revealed a significant underperformance of the MD patients (21.1% [12.6, 29.6]) in contrast to the non‐MD controls (39.1% [30.9, 47.4]) 12 months post‐CI. Self‐assessed hearing disability was significantly more pronounced in MD patients with a mean total SSQ12 score of 3.6 [2.4, 4.9] in comparison to 6.1 [5.4, 6.8] of the matched non‐MD controls after 12 months of cochlear implantation. Conclusion Cochlear implantation substantially improves hearing capabilities in profoundly hearing‐impaired patients with MD, but they tend to underperform in comparison to non‐MD patients at least at lower sound pressure levels. This is likely one reason for the poorer self‐assessed hearing function of cochlear implanted MD patients. Level of Evidence 3, retrospective, nonrandomized follow‐up study.

Introduction: Each type of prosthesis for ossiculoplasty has its advantages and disadvantages, and the choice of the best material has been a matter of various studies. The present study aimed to make a comparison between the hearing outcomes of partial ossicular replacement prosthesis (PORP) using titanium versus Polycel prosthesis. Material and Methods: A total of 106 patients undergoing PORP as a second stage ossiculoplasty were analyzed in this study. Following that, they were randomly assigned to two groups of titanium (n=54) and Polycel (n=52) prosthesis. Subsequently, pre-and post-operative audiometric data were assessed based on the aim of the study. Results: In general, the post-operative air-bone gap within 20 dB was given to 63.5% and 55.6% of all ears in the Polycel and titanium groups, respectively, indicating a non-significant difference (P=0.407). Finally, no SNHL was observed in the groups. Conclusion: Overall, the hearing outcomes and the success rate of PORP are comparable between titanium and Polycel prostheses. Therefore, the selection of these prostheses could be based on the surgeons’ preferences, availability, and cost.

Background: Sudden sensorineural hearing loss (SSHL) refers to the sudden occurrence of unexplained sensorineural hearing loss. The present study showed that different systemic diseases had different influence on the occurrence and hearing outcome of SSHL. Thyroid hormone is one of the important factors for the development of fetal ear and auditory function. However, the distribution of thyroid dysfunction in SSHL patients and the effect of thyroid dysfunction on the occurrence and hearing outcome of SSHL has not been studied. Methods: In this study, a retrospective analysis had been done in 676 patients with SSHL. We had described the distribution of thyroid function in patients with SSHL in detail, and by the statistical method, analyzed the relationship between the hearing outcome and thyroid dysfunction, respectively. Results: In all patients, 24.41% (165/676) had abnormal thyroid function testing results. The onset age of SSHL in FT3 abnormal group (including low and high group) was younger than that in normal FT3 group. Recovery group had more patients with lower-than-normal T3 level as compared to non-recovery patients. Significant associations between T3 levels and hearing outcome were observed in the subgroup with longer time elapse between symptom onset and treatment (≥14 d). Conclusion: The incidence of thyroid dysfunction in SSHL is significantly higher than in the general population. There was obvious relationship between T3 and FT3 item of thyroid dysfunction and the onset time and hearing outcome of SSHL, which indicated that T3 or FT3 indicator may be one of the affecting factors for the SSHL. Early screening and diagnosis of thyroid dysfunction, especial T3 level, may help to evaluate the prognosis in SSHL patients.

Introduction Chronic otitis media (COM) with a central perforation or a concomitant cholesteatoma are both inflammatory lesions, however, with different etiologies. Both entities may present with an intact chain, and the final reconstruction is quite similar. Does it also apply for the hearing outcome? Objectives In a retrospective analysis, we investigated the preoperative hearing and the final hearing outcome of two groups of patients: those with COM and those with cholesteatoma, and compared various factors. Methods Patients operated between 2010 and 2019 were entered prospectively into a research database, and the integrity of the ossicular chain, the extent of the cholesteatoma, and the findings on computed tomography (CT) scans were retrospectively analyzed and correlated to the final hearing outcome. Results Out of 210 tympanoplasties for COM, 162 (80%) presented with an intact chain, and 85 (40%) ears could be analyzed. Out of 283 cholesteatoma surgeries, 53 (19%) ears presented with an intact chain. The preoperative air-bone gap (ABG) was worse in the COM group, but the postoperative ABG over the frequencies of 0.5 kHz and 4 kHz was the same (10 dB to 12 dB) in both groups, and remained within 20 dB in 90% (40 and 78 patients, respectively). The extension of the disease was rather limited in the cholesteatoma group (stages Ch1a and 1b), and better pneumatization and ventilation were beneficial for a good result. Postoperatively, the frequency of 4 kHz had the largest ABG (14 dB and 18 dB). Conclusion Overall, 80% of the patients with COM and less than 20% of those with cholesteatoma had an intact and mobile chain at surgery. Using equivalent surgical techniques for the tympanoplasty, the final outcome was almost the same for both groups, with a mean ABG of 10 dB to 12 dB.
