Department of ENT & Head-Neck Surgery in Sher-E-Bangla Medical College Hospital, Barishal from September 2014 to February 2015. All patients attended in the Department of ENT and Head Neck Surgery in Sher-E-Bangla Medical College Hospital, Serum TSH, USG of thyroid swelling and FNAC were done for diagnoses and for evaluation. \u0000Results: Thyroglossal cysts and sinuses were found in 23(63.9%) and 13(36.1%) cases respectively. The mean age of presentation was found 16.6±11.3 years in cysts group and 15.5±7.2 years in sinus group. Regarding the site of cysts 4(17.4%) cases was suprahyoid, 11(47.8%) infrahyoid and 8(34.8%) at the level of hyoid. Regarding the site of sinus 1(7.7%) case was suprahyoid, 9(69.2%) infrahyoid and 3(23.1%) at the level of hyoid. All the patients had normal thyroid gland in both group, all of them had normal serum TSH level. FNAC was done in all cyst patients and shows normal cystic lesion with no malignancy. But in sinus patients only one FNAC was done and reported as cystic lesion. \u0000Conclusion: Thyroglossal cysts and sinuses were more common in 2nd decade and male predominant. Majority of the cysts are Infrahyoid and on the right side of midline and majority of sinuses are Infrahyoid and on the right side. Development of sinuses is due to operation following abscess formation in majority of cases. \u0000Bangladesh J Otorhinolaryngol 2022; 28(1): 7-15","PeriodicalId":53915,"journal":{"name":"Bangladesh Journal of Otorhinolaryngology","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2022-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47304596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Surgical challenges of CI include difficulties associated with electrode insertion and facial nerve stimulation. Improvement in speech discrimination scores and overall satisfaction with stapedotomy and hearing aid use are reportedly poor in many patients, yet being a low cost procedure it may be used as initial management in a subset of patients. \u0000Case Report: 46 year old patient with diffuse confluent retrofenestral otoscerosis underwent cochlear implantation. He was mapped using behavioral thresholds as despite intracochlear electrode position no neural response was recordable per-operatively as well as in the postoperative period. Perimodiolar electrodes and sodium flouride therapy were used to overcome problems of FNS. 18 months post CI the patient has good audiologic outcomes (CAP 7) without any FNS. \u0000Conclusion: High resolution computed tomography, air bone gap and speech discrimination scores are important in formulating treatment plan in patients with far advanced otosclerosis. Early cochlear implantation can be considered in patients with poor speech discrimination scores and extensive cochlear lesions. Facial nerve stimulation can be prevented by adequate pre-operative planning. \u0000Bangladesh J Otorhinolaryngol 2022; 28(1): 112-117","PeriodicalId":53915,"journal":{"name":"Bangladesh Journal of Otorhinolaryngology","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2022-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42348697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most often otosclerotic foci appear in stapes region leading to stapes fixation, predominantly affect the adolescence female. The most common presenting symptom of clinical otosclerosis is conductive deafness. The mainstay of treatment for otosclerosis is surgery. Surgical options include stapedectomy, stapedotomy with or without stapedial tendon preservation. The latter being is the procedure of choice.\u0000Aim: The aim of this study is to compare the outcome of uncomfortable loudness level in stapedotomy with or without stapedial tendon preservation.\u0000Methods: A prospective observational study was conducted in the Department of Otolaryngology-Head & Neck Surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka for 18 months in patients with otosclerosis. Total 30 subjects were selected based on the inclusion and exclusion criteria. All patients were assessed pre-operatively by clinical examination, otoscopy and microscopic examination. Hearing was assessed by pure tone audiometry. Uncomfortable level and stapedial reflex threshold were tested in all cases. The selected cases were placed into two groups. Stapedial tendon resection in Group-I and stapedial tendon preservation in Group-II. Post-operative follow up was done at 3 months and 6 months. Hearing and uncomfortable loudness level were evaluated with PTA during follow up by calculating the average of 500Hz, 1000Hz, 2000Hz and 4000HZ. The data were calculated manually. The statistical significance was set to P< 0.05. Results of the study were expressed as mean, standard deviation (± SD), frequency and percentages. Means and standard deviations were reported for continuous variables. Frequencies and percentages were reported for categorical variables. Unpaired Student’s t test was done to compare the continuous variables and Chi Square test was done to compare the categorical variables.\u0000Results: In this study preoperative average ABG for group I and group II were 35 ± 4.57 dB and 34 ± 4.17 dB respectively. In group I, post operative average ABG after 3 months and 6 months were 14 ± 3.7 dB and 13±3.3 dB respectively. Post operative average ABG after 3 months was 13 ± 5.7 dB and was 12 ± 4.4 dB for group II. But the hearing improvement between two groups was not statistically significant. In case of preoperative mean UCL was 95 ± 1.8 dB and 96 ± 2.5 dB for group I and group II respectively.

It is the commonest ear problem in adult and children. Most common presenting symptoms are ear discharge, mild to severe hearing loss, sometimes tinnitus even vertigo. Treatment of COM is mainly operative. Inactive mucosal variety of COM presents with the perforation in tympanic membrane with non-inflamed middle ear mucosa. The treatment of inactive mucosal variety of COM is Type 1tympanoplasty. It can be done by conventional temporalis fascia or cartilage graft. Both have some merits and demerits.\u0000Objective: To compare the the outcomes between reinforcement cartilage graft and temporalis fascia graft in type -1 tympanoplasty.\u0000Methods: 86 (43 patients in each group) patients with COM (inactive mucosal) who were admitted in the department of Otolaryngology – Head and Neck Surgery, Bangabandhu Sheikh Mujib Medical University, Dhaka from January 2018 to June 2019, and had fulfilled the inclusion and exclusion criteria were selected for the study. History, examinations, investigations were done. All patients underwent type 1 tympanoplasty.
