Abstract Background Secretory carcinoma (SC) has been described as a distinct salivary gland tumor in the fourth edition of the World Health Organization (WHO) classification of head and neck tumors. SC is generally considered as a slow-growing low-grade malignant tumor, while several cases have been reported with high-grade features, and even metastases in the literature up until now. In this article, a soft tissue SC case is discussed with high-grade microscopic features and neural invasion. A review of the salivary gland SC cases with aggressive behavior is also debated. Case presentation A 65-year-old Caucasian man presented with a left neck mass for the past six months. The imaging studies demonstrated a very large cystic cervical mass (46 × 23 mm) with papillary projections in the anterolateral aspect of the left neck zone Vb. He underwent left radical neck dissection (level I-V) and was followed up for 12 months with the diagnosis of Secretory carcinoma. Conclusion Although SC generally has a good outcome, multiple recurrences and unusual metastases may occur, which should be considered by either the pathologists or clinicians.

Abstract Background Chronic Rhinosinusitis (CRS) is a paranasal sinus inflammatory disease and is divided into two subgroups defined as CRS with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP). CRSwNP displays a T helper (Th)2 biased phenotype, and based on sensitivity or tolerance to aspirin or non-steroidal anti-inflammatory drugs (NSAID), is further subdivided into Aspirin-exacerbated respiratory disease (AERD) and non-AERD groups. Considering the challenge of diagnosis and treatment in patients with CRSwNP, particularly the AERD subtype, and the significance of endotyping in these patients, we examined the immune profile and endotyping based on gene expression analysis in the AERD and the non-AERD groups of patients with CRSwNP. Material and method In this study, 21 patients were enrolled and were categorized into AERD (N = 10) and non-AERD (N = 11) groups based on their sensitivity to aspirin. After the special washing period, nasal polyps were biopsied in both groups, and the infiltration of eosinophils, neutrophils, plasma cells, and lymphocytes was compared between the AERD and the non-AERD groups. Also, gene expression levels of transcription factors including Tbet, GATA3, RoRγt, and FoxP3 and inflammatory cytokines including interleukin (IL)1β, IL1RAP (IL1 receptor accessory protein), IL2, IL4, IL5, IL10, IL13, IL17, TNFα, and IFNγ were investigated by quantitative Real-time PCR (qRT-PCR). Statistical analyses were performed using analytical tests including Kolmogorov–Smirnov, Mann-Whitney, and T-test. A P value less than 0.05 was considered statistically significant. Results The mean ± SD age of the studied groups was 37 ± 8.7 years old (21–50) for the AERD, and 40.4 ± 7.7 years old (31–52) for the non-AERD. LMS/EPOS/SNOT scores and pulmonary function tests showed no difference between the two groups. Serum immunoglobulin E (IgE) levels were found to be higher in patients with AERD (p = 0.04), however, the peripheral blood counts of eosinophils were comparable in the two groups. In the histopathologic analysis, the AERD group showed higher percentages of eosinophils (p = 0.04), neutrophils (p = 0.04), and plasma cells (p = 0.04) than the non-AERD group. Additionally, the gene expression levels of GATA3 (p = 0.001), IL4 (p = 0.04), IL5 (p = 0.007), and IL17 (p = 0.03) were significantly higher in the AERD than the non-AERD groups. Conclusion Higher gene expression levels of GATA3, IL4, IL5, and IL17 were observed in the AERD group compared with the non-AERD group. These findings point to distinct patterns of inflammation in patients with AERD, with a predominance of Th2 inflammation.

Abstract Background Psammomatoid ossifying fibroma (POF) is a rare craniofacial neoplasm, primarily affecting the maxillofacial region, and typically observed in adolescents and young adults. This case report presents a unique occurrence of POF in a 50‐year‐old male, defying the conventional age range and exhibiting an unusual anatomical location within the frontal sinus. Case A 50‐year‐old male with a prior history of cecal adenocarcinoma and colectomy presented with left eye proptosis and new‐onset headaches. Imaging revealed a well‐defined calcified mass in the left frontal sinus, leading to a diagnosis of POF. Open surgical resection was performed to remove the tumor, and histopathological evaluation confirmed its diagnosis as psammomatoid ossifying fibroma. The patient exhibited no postoperative complications or signs of recurrence. Conclusion This case underscores the diverse clinical presentations and diagnostic challenges associated with POF, emphasizing the importance of accurate diagnosis and multidisciplinary collaboration. Further research is needed to explore the genetic underpinnings and optimal management strategies for this intriguing condition.

Introduction:Intravascular papillary endothelial hyperplasia (IPEH) is a papillary hyperplasia of the endothelial vascular cells, also called Masson's tumor. Masson's etiology and risk factors remain unclear but trauma and vascular pathologic conditions may start the tumor process from its common regions like extremities. Common presentations include swelling and mild pain. Our Radiologic modality of choice is Contrast-enhanced MRI which can help us before operating parotidectomy, the gold standard of tumor treatment. As presented in this study, Parotid Masson's tumor, is a very rare form of Masson's,making it even more exceptional.Case Report: This paper reports a case of a 29-years-old woman with a mass in herright parotid gland from 17 years ago, which has slowly increased in size during these years. She underwent a total parotidectomy following unsuccessful Fibrovein injections, which caused her inflammation. Embolization was performed before the resection to decrease the risk of its hemorrhage. Postoperative follow-up confirmed the reliability of this treatment method as the patient declared no side effects. Apart from its tough diagnosis, since Masson's tumors, especially the ones that emerge in the parotid, are rare, we decided to introduce this case to deliver more information about the treatment and diagnosis of this rare disease to other colleagues.Conclusions:The prognosis of parotid Masson's is admirable following a total resection. The patient had no postoperative complaints with no need for multiple visits after resection.

AbstractIntroduction:Recent advances have led to the development of sialendoscopy, an accurate, minimally invasive procedure with high diagnostic and therapeutic capabilities in treating sialolithiasis. This study aimed to evaluate the results and complications of sialendoscopy in patients suffering from sialoadenitis.Materials and Methods: This study was a prospective interventional case series study on patients with sialoadenitis due to sludge or stone formation preoperatively confirmed by sonography or computed tomography (CT) scanning. Diagnostic sialendoscopy was performed, and the presence of stenosis, sludge, or stones inside the gland or duct was examined, and surgery was done. During follow-up time (18.8 ± 7.4 months), recurrence of symptoms, the need for reoperation, and postoperative complications were also assessed.Results: The sialendoscopy was performed in 51 patients, including 55 glands. Forty-five Patients (88.2%) reported pain relief, and 46 patients (90.2%) reported that the treatment using sialendoscopy was better than conservative methods. The duct restenosis also occurred in one patient requiring open surgery. In assessing the main factors predicting the need for reoperation, the site of involvement (parotid versus submandibular glands) and the size of the stone were identified as the main determinants. The best cut-off value for stone size in predicting reoperation requirement was 7.0mm, with a sensitivity of 100% and a specificity of 85.7%.Conclusion: Intraoperative sialendoscopy is a successful diagnostic and therapeutic tool with minimal postoperative complications in salivary gland duct involvement patients.

Introduction: Operations on the tympanic membrane of the middle ear, myringoplasty, and tympanoplasty are now widely accepted, and attempts are underway all over the world to standardize the surgical techniques. This study aimed to compare postoperative outcomes of endoscopic and microscopic cartilage myringoplasty in patients suffering from chronic otitis media (COM). Materials and Methods: This clinical trial study compared 130 patients with COM who underwent transcanal endoscopic myringoplasty by repairing perforation using auricular concha cartilage under general anesthesia (n=75) and conventional repairing method by postauricular incision and tympanomeatal flap elevation under microscopic surgery (n=55). Results: According to the results, there was no significant difference between the two groups in terms of hearing gain 1, 6, and 12 months after surgery (P=0.063); however, higher hearing gain scores were observed in the endoscopic group. Moreover, lower recovery time and post-operative pain were reported in patients who underwent the endoscopic approach, compared to those who treated with the conventional repairing method (P

Vestibular schwannoma is a benign and common slow-growing tumor that develops on the vestibular divisions of cranial nerve VIII. Some risk factors may enhance intratumoral hemorrhage risk which leads to tumor management to early surgical procedures. Hence, we describe a 57-year-old man presented with hearing loss and a 5*8 mm vestibular schwannoma. Eight months later, the patient was referred with headache, nausea and vomiting, right hemifacial paresis, and hemiparesis. Magnetic resonance imaging (MRI) revealed a 45*35 mm hemorrhagic vestibular schwannoma. Surgical pathology reported hemorrhagic vestibular schwannoma. This was a rare case of hemorrhagic vestibular schwannoma with none of the established risk factors for the intratumoral hemorrhage and presented with Wallenberg-like syndrome. Many risk factors can cause hemorrhagic vestibular schwannoma. We present one case of small vestibular schwannoma without any predisposing of hemorrhage and acute onset of same side hemifacial paresis and hemiparesis.

Otorhinolaryngology ,RF1-547 - Abstract
Introduction. The introduction of laryngeal transoral procedures has created a shift in the treatment of laryngeal cancers towards the primary surgical management of patients. In this study, we aimed to evaluate the safety, efficacy, and feasibility of the transoral laser-assisted total laryngectomy (TLM-TL) in advanced laryngeal cancer. Case presentation. In this case report, we describe a case of a 50-year-old male patient presented to the otorhinolaryngology clinic with a history of hoarseness and odynophagia since 6 months. Based on the pathological and imaging findings, the diagnosis of stage IVa laryngeal squamous cell carcinoma with the involvement of the base, tongue, and left palatine tonsil was made for the patient, and transoral total laryngectomy with partial glossectomy via the TLM technique was planned. Result. The tumor was successfully resected by TLM-TL with clear surgical margins. No complication was observed after the surgery. Good functional recovery was obtained regarding swallowing and speech. The patient’s oncologic and functional outcomes were evaluated for 2 years. Everything was satisfactory with good long-term cosmetic and laryngopharyngeal functional outcome and no sign of tumor recurrence. Conclusions. TLM-TL is a minimally invasive and cost-benefit endoscopic surgical procedure feasible in advanced laryngeal cancer with good long-term oncological and functional outcome. It could limit postoperative complications, mainly the incidence of pharyngocutaneous fistulae. It is also associated with better satisfaction after TL due to cosmetic benefits.

Introduction: Different approaches have been developed to find the position of the internal auditory canal (IAC)in middle cranial fossa approach. A feasibility study was performed to investigate the combination of cone beam computed tomography (CBCT), optical coherence tomography (OCT), and laser ablation to assist a surgeon in a middle cranial fossa approach by outlining the internal auditory canal (IAC). Materials and Methods: A combined OCT laser setup was used to outline the position of IAC on the surface of the petrous bone in cadaveric semi-heads. The position of the hidden structures, such as IAC, was determined in MATLAB software using an intraoperative CBCT scan. Four titanium spheres attached to the edge of the craniotomy served as reference markers visible in both CBCT and OCT images in order to transfer the plan to the patient. The integrated erbium-doped yttrium aluminum garnet laser was used to mark the surface of the bone by shallow ablation under OCT-based navigation before the surgeon continued the operation. Result: The technical setup was feasible, and the laser marking of the border of the IAC was performed with an overall accuracy of 300 μm. The depth of each ablation phase was 300 μm. The marks indicating a safe path supported the surgeon in the surgery. Conclusion: The technique investigated in the present study could decrease the surgical risks for the mentioned structures and improve the pace and precision of operation.

Introduction: Glomus tympanicum (GT) is a benign primary tumor of the middle ear. The evolution of endoscopic ear surgery has allowed for an alternative approach to managing this vascular tumor. The purpose of this study was to evaluate an endoscopic approach in GT surgery, and also to investigate its applicability and feasibility. Materials and Methods: Prospectively, 13 class I and II patients, according to the Glasscock-Jackson glomus classification, were candidates for management via a transcanal endoscopic approach. Patients were categorized into three groups according to the location of the tumor in the middle ear. Group A consisted of patients with tumors located anteriorly while occupying the Eustachian tube. Group B were patients with tumors located on the promontory with entirely visible tumor borders. Patients in Group C had tumors that occupied the entire middle ear. Under specially designed flap elevation and hemostasis, the tumors were completely removed using an endoscopic technique. Results: Based on the classification criteria, three patients fell into Group A (30%), six into Group B (46%), and three into Group C (23%). The principal chief complaint was pulsatile tinnitus that disappeared after surgery in most cases. Hearing status was mostly mixed hearing loss. No change was detected in bone conduction after surgery, but air conduction was improved in nine cases. No major complication or recurrence was observed over 30 months of follow up. Conclusion: Improved exposure and access in the endoscopic transcanal approach to GT leads to safe, rapid, and reliable tumor removal, as well as allowing comfortable surgery for both the surgeon and most patients.

Introduction:Visualization of inner ear structures is a valuable strategy for researchers and clinicians working on hearing pathologies. Optical coherence tomography (OCT) is a high-resolution imaging technology which may be used for the visualization of tissues. In this experimental study we aimed to evaluate inner ear anatomy in well-prepared human labyrinthine bones.Materials and Methods:Three fresh human explanted temporal bones were trimmed, chemically decalcified with ethylenediaminetetraacetic acid (EDTA), and mechanically drilled under visual control using OCT in order to reveal the remaining bone shell. After confirming decalcification with a computed tomography (CT) scan, the samples were scanned with OCT in different views. The oval window, round window, and remnant part of internal auditory canal and cochlear turn were investigated.Results:Preparation of the labyrinthine bone and visualization under OCT guidance was successfully performed to a remaining bony layer of 300µm thickness. OCT images of the specimen allowed a detailed view of the intra-cochlear anatomy.Conclusion:OCT is applicable in the well-prepared human inner ear and allows visualization of soft tissue parts.

The present study focuses on the application of scanning laser optical tomography (SLOT) for visualization of anatomical structures inside the human cochlea ex vivo. SLOT is a laser-based highly efficient microscopy technique which allows for tomographic imaging of the internal structure of transparent specimens. Thus, in the field of otology this technique is best convenient for an ex vivo study of the inner ear anatomy. For this purpose, the preparation before imaging comprises decalcification, dehydration as well as optical clearing of the cochlea samples in toto. Here, we demonstrate results of SLOT imaging visualizing hard and soft tissue structures with an optical resolution of down to 15 μm using extinction and autofluorescence as contrast mechanisms. Furthermore, the internal structure can be analyzed nondestructively and quantitatively in detail by sectioning of the three-dimensional datasets. The method of X-ray Micro Computed Tomography (μCT) has been previously applied to explanted cochlea and is solely based on absorption contrast. An advantage of SLOT is that it uses visible light for image formation and thus provides a variety of contrast mechanisms known from other light microscopy techniques, such as fluorescence or scattering. We show that SLOT data is consistent with μCT anatomical data and provides additional information by using fluorescence. We demonstrate that SLOT is applicable for cochlea with metallic cochlear implants (CI) that would lead to significant artifacts in μCT imaging. In conclusion, the present study demonstrates the capability of SLOT for resolution visualization of cleared human cochleae ex vivo using multiple contrast mechanisms and lays the foundation for a broad variety of additional studies.

Background:Over the past 20 years, the minimally invasive endoscopic approach has gained widespread acceptance. The study was performed to evaluate the diagnostic method and the success rate of endoscopically diagnosed and treated CSF rhinorrhea, and also investigations such as leakage site and etiologic factor. Methods: This retrospective CSF leakage management review of patients experiencing CSF rhinorrhea made from 1999-2006 included data regarding leakage etiology, preoperative assessment,intraoperative techniques and postoperative followup.Result: Sixty-five patients were managed endoscopically. CSF rhinorrhea etiology was traumatic in 30 cases, iatrogenic in 23 and spontaneous in 12. We used nasal endoscopy and high resolution computed tomography (HRCT) in all 65 cases while CT metrizamide cisternography was used in 5 specifically and magnetic resonance imaging for 5 others. Intrathecal fluorescein was used for intraoperative assessment without complications, and only one case of meningismus was noted. Conclusion: Several imaging methods were effective in diagnosing CSF leakage sites. Endoscopic management and autografts were successful in repairing anterior skull defects in 90.76% of the cases.

- Abstract
Background: Nasal chondromesenchymal hamartoma (NCMH) is a rare benign tumor almost always found in children. NCMH was first described by McDermott in 1998. To the best our knowledge, about 50 NCMH cases have been reported worldwide with very few adult cases and no long-term follow-ups. Case Presentation: Here, we report a 43-year-old woman who referred to the Otolaryngology Clinic of Payambar Azam Hospital, Bandar Abbas, Iran, in 2008, with a one-year history of progressive left-sided nasal obstruction that had not relieved with topical nasal decongestants and steroid sprays. A unilateral left-sided nasal soft-tissue mass was found upon examination. Histological and immunohistochemical analyses were consistent with NCMH. Trans-nasal endoscopic excision showed good results and no sign of recurrence has been observed after 12 years of regular follow-up. Conclusion: Awareness of imaging and immunohistochemical characteristics of NCMH combined with the probability of presentation in the adult population are necessary for correct diagnosis and adequate therapy.

This multicenter study aimed to evaluate the auditory and speech outcomes of cochlear implantation (CI) in deaf-blind patients compared with deaf-only patients.Retrospective cohort study.Multiple cochlear implant centers.The current study was conducted on 17 prelingual deaf-blind children and 12 postlingual deaf-blind adults who underwent CI surgery. As a control group, 17 prelingual deaf children and 12 postlingual deaf adults were selected.Cochlear implantation.Auditory and linguistic performances in children were assessed using the categories of auditory performance (CAP) and Speech Intelligibility Rating (SIR) scales, respectively. The word recognition score (WRS) was also used to measure speech perception ability in adults. The mean CAP, SIR, and WRS cores were compared between the deaf-only and deaf-blind groups before CI surgery and at "12 months" and "24 months" after device activation. Cohen's d was used for effect size estimation.We found no significant differences in the mean CAP and SIR scores between the deaf-blind and deaf-only children before the CI surgery. For both groups, SIR and CAP scores improved with increasing time after the device activation. The mean CAP scores in the deaf-only children were either equivalent or slightly higher than those of the deaf-blind children at "12 months post-CI" (3.94 ± 0.74 vs 3.24 ± 1.25; mean difference score, 0.706) and "24 months post-CI" (6.01 ± 0.79 vs 5.47 ± 1.06; mean difference score, 0.529) time intervals, but these differences were not statistically significant. The SIR scores in deaf-only implanted children were, on average, 0.870 scores greater than the deaf-blind children at "12 months post-CI" (2.94 ± 0.55 vs 2.07 ± 1.4; p = 0.01, d = 0.97) and, on average, 1.067 scores greater than deaf-blind children at "24 months post-CI" (4.35 ± 0.49 vs 3.29 ± 1.20; p = 0.002; d = 1.15) time intervals. We also found an improvement in WRS scores from the "preimplantation" to the "12-month post-CI" and "24-month post-CI" time intervals in both groups. Pairwise comparisons indicated that the mean WRS in the deaf-only adults was, on average, 10.61% better than deaf-blind implanted adults at "12 months post-CI" (62.33 ± 9.09% vs 51.71 ± 10.73%, p = 0.034, d = 1.06) and, on average, 15.81% better than deaf-blind adults at "24-months post-CI" (72.67 ± 8.66% vs 56.8 ± 9.78%, p = 0.002, d = 1.61) follow-ups.Cochlear implantation is a beneficial method for the rehabilitation of deaf-blind patients. Both deaf-blind and deaf-only implanted children revealed similar auditory performances. However, speech perception ability in deaf-blind patients was slightly lower than the deaf-only patients in both children and adults.

Adenoid cystic carcinoma (ACC) is a slow-growing malignancy that most often occurs in the salivary glands. Although reasonable local control is usually achieved by tumor surgery and subsequent radiation therapy, recurrence at the same or distant site is the cause of treatment failure. Currently, no FDA-approved therapeutic target or diagnostic biomarker has been identified for this cancer. To find the therapeutic and diagnostic targets for ACC, we extracted the gene expression information from two GEO datasets. Different expression genes (DEGs) between ACC and normal samples were extracted and used to explore the biochemical pathways involved in ACC and create a protein-protein interaction (PPI) network.After analyzing the PPI network, 20 hub genes were introduced that have potential as diagnostic and therapeutic target. Among them, PLCG1 and EZH2 were introduced as new biomarkers in ACC that might have a high value in the diagnosis and treatment of ACC. Furthermore, by studying the roles of the hub genes in the enriched biochemical pathways, we found that most likely, IGF-1R/IR and PPARG pathways play a critical role in tumorigenesis and drug resistance in the ACC and have a high potential for selection as a therapeutic target in future studies.

The purpose of the study is to evaluate the efficacy of double skin paddle anterolateral thigh flap (ALT) to reconstruction of through and through oral cavity defect due to cancer surgery.A prospective review was performed of patients referred to Firoozgar and Erfan hospitals with oral cavity defects with two or more oral cavity subunits and skin simultaneously involvement and immediate reconstruction using double-skin paddle ALT flap at the same time of tumor ablation from January 2019 to November 2020.A total number of 6 patients was evaluated. The mean area of skin paddle was 110.4 cm2 and 92.8 cm2 in distal and proximal paddle respectively. Except one patient was complicated and expired in hospital admission, the remaining 5 patients got fully oral intake and completely survived flaps with primarily closed donor site. Tumor recurrence was not found in the mean follow-up time of 12 months.The double skin paddle anterolateral thigh flap serves as an efficient reconstruction technique in complex and perforating oral cavity defects with the same functional outcome and the same flap related complications as conventional ALT flap.

Introduction Pitch mismatch is one of the most important problems of users of bimodal cochlear implants, which affects their life satisfaction. Children with acquired hearing loss cannot explain their pitch mismatch problems, as they have had no auditory experience. This study tries to diagnose pitch mismatch in these children through the sound-induced flash illusion test. Materials and methods In this study, 20 children with a bimodal cochlear implant and 20 children with normal hearing, within the age range of 8 to 13 years old, were examined using the sound-induced flash illusion test. In this test, participants received one flash with one to four beep sounds, and they were asked to indicate the number of perceived flashes. Results The results revealed that in the bimodal implantation group, when the flash was provided with one beep, at certain frequencies, children expressed that they saw two flashes. However, the results were not the same in children with normal hearing. Conclusion The results indicated that at frequencies where the auditory information of the hearing aids and those of the cochlear implants overlap, pitch mismatch develops, which can significantly affect the auditory performance of bimodal users.

To evaluate the auditory performance and speech production outcome in children with auditory neuropathy spectrum disorder (ANSD). The effect of age on the outcomes of the surgery at the time of implantation was also evaluated.Cochlear implantation was performed in 136 children with bilateral severe-to- profound hearing loss due to ANSD, at four tertiary academic centers. The patients were divided into two groups based on the age at the time of implantation; Group I: Children ≤24 months, and Group II: subjects24 months. The categories of auditory performance (CAP) and speech intelligibility rating (SIR) scores were evaluated after the first and second years of implantation. The differences between the CAP and SIR scores in the two groups were assessed.The median CAP scores improved significantly after the cochlear implantation in all the patients (p value 0.001). The improvement in the CAP scores during the first year in Group II was greater than Group I (p value: 0.007), but the improvement in CAP scores tended to be significantly higher in patients who were implanted at ≤24 months (p value 0.001). There was no significant difference between two groups in SIR scores at first-year and second-year follow-ups. The evaluation of the SIR improvement revealed significantly higher values for Group I during the second-year follow-up (p value: 0.003).The auditory performance and speech production skills of the children with ANSD improved significantly after cochlear implantation, and this improvement was affected by age at the time of implantation.

BackgroundThe lateral skull base lesions are one of the most challenging parts of the head and neck. Surgical approaches for this area are complex and difficult. Although endoscopic approaches in skull base surgeries have progressed dramatically in recent years, there are few studies concerning these approaches.ObjectivesThis study aimed to describe the endoscopic transcanal transcochlear approach (ETTA) to reach the internal auditory canal (IAC) in the cadaveric temporal bone specimen.MethodsFirst, pre- and post-operative high resolution computed tomography (HRCT) images of the transcanal transcochlear pathway were obtained and 3D segmentation was performed using 3D Slicer software. The anatomic landmarks were identified using the endoscopic approach with and without navigation guide. Surgeries were done and the feasibility and challenges were evaluated.ResultsThe internal auditory canal (IAC) was accessed via the ETTA. Anatomic landmarks were looked and a surgical corridor was identified with HRCT segmentations and images obtained during surgery.ConclusionsWe tried to increase our learning curve and extend surgical experience in lateral skull base surgery via minimally invasive ETTA. The increased endoscopic skills and the use of auxiliary tools such as a navigation guide may be helpful for successful access to the lateral skull base.

This multicenter study evaluated the auditory performance and speech production outcomes of cochlear implantation in children with inner ear anomaly and compared the outcomes of patients with different kinds of malformation.Cochlear implantation was performed in 107 children with inner ear malformation at four tertiary academic centers. The categories of auditory performance (CAP) and speech intelligibility rating (SIR) scores were evaluated preoperatively and one year and two years postoperatively.Types of inner ear malformation and their frequencies were: incomplete partition type-I, 19 (17.8%) patients; incomplete partition type-II, 31 (29%), common cavity, 17 (15.9%), cochlear hypoplasia, 17 (15.9%), and isolated enlarged vestibular aqueduct (isolated EVA), 23 (21.5%) patients. EVA was the coexisting anomaly in 27(25.2%) subjects. The median CAP and SIR scores improved significantly during the first two years after cochlear implantation in all groups (p-values0.001 and 0.001, respectively). No significant difference was seen in CAP and SIR scores of children with different inner ear malformations (p-value = 0.147 and 0.570, respectively) or in patients with isolated EVA compared to coexisting EVA (p-value = 0.538 and 0.075, respectively).The median CAP and SIR scores two years after surgery were 5 (Understanding of common phrases without lip-reading) IQR: 4-6, and 3 (Connected speech is intelligible to a listener who concentrates and lip-reads within a known context) IQR: 3-4, respectively. Auditory performance and speech production were significantly improved in all inner ear malformation patient groups, and no significant difference was observed between the scores of patients with different types of anomaly.

Background: Ménière’s disease (MD) is a common inner ear disorder which is characterized by recurrent attacks of vertigo, fluctuating sensorineural hearing loss (SNHL), tinnitus, and a sense of fullness in the affected ear. MD is a complex disorder; although six genes have been linked to familial autosomal dominant form of the disease, in many cases, the exact genetic etiology remains elusive. Methods: To elucidate the genetic causes of MD in an Iranian family, we performed exome sequencing on all members of the family: consanguineous parents and four children (two affected and two unaffected). Variant filtering was completed using a customized workflow keeping variants based on segregation with MD in autosomal recessive (AR) inheritance pattern, minor allele frequency (MAF), and in-silico prediction of pathogenicity. Results: Analysis revealed that in this family, 970 variants co-segregated with MD in AR pattern, out of which eight variants (one intergenic, four intronic, and three exonic) were extremely rare. The exonic variants included a synonymous substitution in USP3 gene, an in-frame deletion in ZBED2 gene, and a rare, highly conserved deleterious missense alteration in LSAMP gene. Conclusion: The phenotype observed in the proband described here, i.e. vertigo, poor sense of smell, tinnitus, and borderline hearing ability, may originate from aberrant changes in the cerebellum and limbic system due to a deleterious mutation in the LSAMP gene; hence, LSAMP mutation is a possible candidate for the etiology of MD in this family.

Mucormycosis, an uncommon and rapidly progressive fungal infection, is mainly seen in immunocompromised patients. However, immunocompetent individuals can also be infected. Here, we present a rapidly progressive orbito-cerebral mucormycosis in an immunocompetent patient, who had a history of entry of an insect into his eye. We report an immunocompetent patient, who had a history of entry of an insect into his eye, presented with left eye panophthalmitis, cellulitis and loss of vision. He underwent orbital exenteration. Then, mucormycosis was diagnosed and amphotericin B was initiated. Left cavernous sinus and internal carotid artery involvement were found in brain magnetic resonance imaging (MRI) and cerebrovascular accident (CVA) was diagnosed. Surgical debridement of necrotic tissue was performed, and postoperatively, our patient died following CVA. Mucormycosis, as a fatal fungal infection, requires early diagnosis, appropriate early surgical and rapid antifungal management so that successful outcome can be achieved.

Cisplatin, as a platinum-based chemotherapeutic medication, is applied for various types of solid tumors. Regarding the treatment of cancer cells, cisplatin is potentially accompanied with some side effects such as nephrotoxicity, neurotoxicity, and ototoxicity in spite of high efficacy of Cisplatin. The present study aimed to determine whether the use of oral sertraline can contribute to preserve hearing threshold among the patients who receive cisplatin or not. This research has done for one year, along with a 3 months course and follow-up. This is a double-blind, randomized, and placebo-controlled trial study. The study was conducted in Oncology Clinic and Audiology Department of Firoozgar University Hospital in Tehran, Iran. Among 112 patients, 79 patients who were suffering from different types of solid tumors and were candidates for receiving cisplatin for chemotherapy treatment were selected. The grade of hearing impairment and otoacoustic emission in the first day and the last stage of the study was used for data analysis. Among 112 patients, 79 patients were randomly selected to receive either sertraline (50 mg/d) as the case group, or placebo as the control group. Before and after the treatments, the patients were assessed by High-Frequency Audiometry and dpOAE tests. First, the two groups were distributed homogeneously based on sex and age. Based on Common Terminology Criteria for Adverse Events (CTCAE), the Ototoxicity Grade indicated a significantly lower grade of deficits in the Sertraline group (p

Background: Introduction of the novel imaging modalities such as optical coherence tomography and scanning laser optical tomography allow the morphological and functional evaluation of the intracochlear structures up to the histological details. The prerequisite of these modalities is the preparation of the membranous labyrinth by removing the dense otic capsule to enhance the optical penetration depth. In the present study, a combination of the chemical decalcification and bone drilling method was explained for the preparation of the human inner ear structures for further studies. Methods: In this study, nine human temporal bones were used and trimmed in cubes containing middle and inner ear structures. The samples were immersed in 5% nitric acid, 20% EDTA, and 10% EDTA solutions, respectively. The samples were brought out and rinsed every 90 minutes, and mechanical removal of the softened bone was performed with surgical drill system until the complete decalcification of the samples was confirmed by X-ray imaging. The prepared samples were evaluated by microcomputed tomography imaging for anatomical distortions caused by the preparation process. Results: Complete decalcification and preparation of the samples were obtained in average of 10.5 ± 0.5 hours. No obvious morphological changes were observed in microcomputed tomography images, except for fracture of the remnant bony shell at the apex of cochlea in one sample. Conclusions: The combination of the chemical decalcification and mechanical removal of the softened bone can accelerate the sample preparation for high resolution imaging studies without significant morphological changes.

This study was conducted to evaluate the effect of the round window membrane accessibility on the residual hearing after cochlear implantation surgery in adults. Moreover, the effects of the other demographics and intra-operative factors on the residual hearing loss have been evaluated. The hearing preservation cochlear implantation surgery was performed on 64 adults with residual hearing thresholds ≤80 dB at 250 and 500 Hz, who had referred to our tertiary academic center. All the patients underwent a standardized surgical approach with the same straight electrode inserted through the round window membrane. The hearing thresholds at 250, 500, and 1000 Hz were compared in pre-operative and 1 month postoperative pure-tone audiograms. The average hearing threshold shifts at these frequencies was used to evaluate the hearing preservation. The effects of the round window accessibility and other factors (including gender, age, side of the surgery, necessity of anterior-inferior drilling of the round window margin and average insertion speed) on hearing threshold shifts were analyzed. The mean low-frequency hearing threshold shift was found to be 17.5 dB for all the patients. The hearing preservation goal (threshold shifts ≤30 dB) was achieved in 58 patients. Among the evaluated parameters, only accessibility of the round window membrane could change the hearing threshold shifts significantly (p = 0.026), and was a predictor for the hearing loss (B coefficient = 7.5, p = 0.006). Incomplete accessibility of the round window membrane may be a predictor for increased hearing threshold shifts in short-term evaluations after cochlear implantation.

The aim of the study was to evaluate insertion forces during manual insertion of a straight atraumatic electrode in human temporal bones, and post-implantation histologic evaluation of the samples to determine whether violation of intracochlear structures is related to insertion forces. In order to minimize intracochlear trauma and preserve residual hearing during cochlear implantation, knowledge of the insertion forces is necessary. Ten fresh frozen human temporal bones were prepared with canal wall down mastoidectomy. All samples were mounted on a one-axis force sensor. Insertion of a 16-mm straight atraumatic electrode was performed from different angles to induce “traumatic” insertion. Histologic evaluation was performed in order to evaluate intracochlear trauma. In 4 of 10 samples, dislocation of the electrode into scala vestibuli was observed. The mean insertion force for all 10 procedures was 0.003 ± 0.005 N. Insertion forces measured around the site of dislocation to scala vestibuli in 3 of 4 samples were significantly higher than insertion forces at the same location of the cochleae measured in samples without trauma (p

(Headache 2010;50:242-248) Background.— Some types of headaches with sinonasal origin may be present in the absence of inflammation and infection. The contact points between the lateral nasal wall and the septum could be the cause of triggering and sustained pain via trigeminovascular system. Objective.— The aim of this study was to evaluate the feasibility and effectiveness of endoscopic surgery in the sinonasal region for treatment of headache with special attention paid to specific diagnostic methods and patient selection. Methods.— This was a prospective, non-randomized and semi-quasi experimental research study. Thirty-six patients with chronic headaches who had not previously responded to conventional treatments were evaluated by rhinoscopy and/or endoscopy, local anesthetic tests and computed tomography scans as diagnostic criteria. These patients were divided into 4 groups based on the diagnostic methods utilized. The intensity of headaches pre- and post-operatively were recorded by utilizing the visual analog scale scale and performing analysis with analysis of variance test comparison and Statistical Package for Social Sciences. Average follow-up was 30 months. Results.— Our overall success rate approximated 83% while the complete cure rate was 11%. Patients in group 4 achieved the best results. In this group all diagnostic criteria were positive. In addition, patient responses were statistically significant in groups with more than one positive criteria compared with group 1 who only had positive examination. The positive response of 14 migrainous patients diagnosed with migraine prior to treatment was 64%. Conclusion.— Surgery in specific cases of headaches with more positive evidence of contact point could be successful, particularly if medical therapy has failed.

Trauma is the fourth major cause of mortality in the Western countries, of which approximately one half involve maxillofacial injury. Statistics reported by emergency room officials show motor vehicles cause many of the injuries and deaths that occur in Iran. Having completed a retrospective descriptive study of 200 patients who experienced maxillofacial trauma, the authors report its occurrence with respect to age, sex, trauma type, and site of injury so as to evaluate the operational functionality of the Department of Otolaryngology and Head & Neck Surgery of Hazrat-e Rasoul Akram Hospital from 2000 to 2004. Mandibular fractures (36.2%) occurred in the subsequently listed sites and at the specified frequencies: mandibular angle (9.7%), mandible body (6.9%), parasymphysis, ramus and subcondyle at 5.6% each, and symphysis at 2.8%. No condylar fractures were reported. Frontal bone fracture was observed in 9.7% of the patients with eye globe injury occurring simultaneously in 8.3% of corresponding cases. Orbital fracture (63.9%) also occurred in various cases as follows: orbital floor 39%, lateral rim 24%, inferior rim 22%, medial wall 11%, and the superior rim and orbital roof at 2% each. Motor vehicle accidents were the most common causes of trauma (42%). The most common fracture was in the zygoma (43%) with 8.3% of them being orbital injury. Fractures of mandibular bones (36.2%) and the maxilla (33%) were the most commonly seen in trauma occurring to the maxillomandibular region.

The present study focuses on the application of scanning laser optical tomography (SLOT) for visualization of anatomical structures inside the human cochlea ex vivo. SLOT is a laser-based highly efficient microscopy technique which allows for tomographic imaging of the internal structure of transparent specimens. Thus, in the field of otology this technique is best convenient for an ex vivo study of the inner ear anatomy. For this purpose, the preparation before imaging comprises decalcification, dehydration as well as optical clearing of the cochlea samples in toto. Here, we demonstrate results of SLOT imaging visualizing hard and soft tissue structures with an optical resolution of down to 15 μm using extinction and autofluorescence as contrast mechanisms. Furthermore, the internal structure can be analyzed nondestructively and quantitatively in detail by sectioning of the three-dimensional datasets. The method of X-ray Micro Computed Tomography (μCT) has been previously applied to explanted cochlea and is solely based on absorption contrast. An advantage of SLOT is that it uses visible light for image formation and thus provides a variety of contrast mechanisms known from other light microscopy techniques, such as fluorescence or scattering. We show that SLOT data is consistent with μCT anatomical data and provides additional information by using fluorescence. We demonstrate that SLOT is applicable for cochlea with metallic cochlear implants (CI) that would lead to significant artifacts in μCT imaging. In conclusion, the present study demonstrates the capability of SLOT for resolution visualization of cleared human cochleae ex vivo using multiple contrast mechanisms and lays the foundation for a broad variety of additional studies. © 2017 Tinne et al.

Objectives Tonsillectomy is one of the most common operations performed in pediatric population. One of the most prevalent tonsillectomy complications is early or delayed post-operative hemorrhage. Other important morbidity is post-operative pain. Historically, honey has been used for wound control, reducing the inflammation, and healing acceleration. The aim of this study is to investigate the effect of honey on reducing pain after tonsillectomy in children 5–15 years old. Methods After tonsillectomy, 80 patients were randomly divided in two equal groups. Patients in the first group were treated with antibiotic and acetaminophen, while those in the second group were treated with antibiotic, acetaminophen and honey. Data was gathered via a questionnaire and observation of tonsillar bed healing. Data was analyzed by SPSS17 software and related tests. Results Pain comparison between two groups showed that the average time required for pain relief in patients who received honey was less than the control. The pain intensity was higher during the first 9 days post-operatively in control group. Results also showed that acetaminophen consumption in patients who received honey is lower. In the case group, the average time to resume regular diet and the frequency of awakening at night is significantly less than the control group. Conclusion Honey administration after tonsillectomy has valuable effect in pain relief and it can be used as an adjunctive regimen after surgery for better pain control.
