One group underwent coblation tonsillectomy while other group with dissection tonsillectomy. Chronic tonsillitis patients with adenoid hypertrophy and Otitis media with effusion were excluded by diagnostic nasal endoscopy, imaging and audiometry. All patient were examined regularly after surgery for 10 days to assess the postoperative morbidity and efficacy of both coblation and dissection methods. Duration of surgery, amount of intraoperative bleeding, recovery time, postoperative pain& requirement of analgesics, time required to regain normal diet & activityand complication were assessed. \u0000Result: Comparing the coblation tonsillectomy to cold dissection group the mean duration of surgery was 9.7 versus 18.4 minutes, the amount of intra operative bleeding 10.62 versus 28.72 milliliter. The difference on the postoperative pain scale, requirement of analgesics, condition of the tonsillar fossa, time required to regain normal diet & activity between two groups were statistically significant. \u0000Conclusion: In our study patient underwent coblation tonsillectomy providing a near bloodless field, minimum operating time, less postoperative pain, quicker return to normal diet, normal activity and less use of analgesics than patients underwent dissection tonsillectomy. Postoperative morbidity and complications were lower as compared to conventional cold dissection technique. \u0000Bangladesh J Otorhinolaryngol; October 2020; 26(2): 121-127","PeriodicalId":53915,"journal":{"name":"Bangladesh Journal of Otorhinolaryngology","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2020-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46193569","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}

The most common presenting symptoms are ear discharge, mild to severe hearing loss, sometimes tinnitus even vertigo. Treatment of COM is mainly operative. The treatment of inactive mucosal variety of COM is Type 1 tympanoplasty. It can be done by microscopic or endoscopic technique. Both methods have some merits and demerits. \u0000Objectives: Aim of the study was to compare the surgical outcomes between endoscopic and microscopic type 1 tympanoplasty. \u0000Methods: This study was carried out in the Department of Otolaryngology–Head & Neck surgery of Bangabandhu Sheikh Mujib Medical University, Dhaka from March 2017 to June 2019 and 60 (30 in each group) patient were included in the study. All patients underwent type 1 tympanoplasty. In Group A endoscopic tympanoplasty cases and in Group B microscopic tympanoplasty cases were placed. Operation duration, post-operative pain, postoperative hearing status, graft uptake was compared in two groups. \u0000Results: There were no significant difference of graft uptake and hearing gain (>0.05). But endoscopic operative time and post-operative pain were less than microscopic group (<0.05). \u0000Conclusion: Through endoscopic tympanoplasty is a newer approach and it has some limitations. As endoscopic tympanoplasty requires less time, less pain with similar graft uptake and audiological success. It can be adopted as an alternative method of tympanoplasty. \u0000Bangladesh J Otorhinolaryngol; October 2020; 26(2): 109-115","PeriodicalId":53915,"journal":{"name":"Bangladesh Journal of Otorhinolaryngology","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2020-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43492924","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}

It results from clonal proliferation of histiocytes which has similarity in morphology and immunophenotype to Langerhans cells located in the skin and mucosa. The Writing Group of the Histiocyte Society recommendedthe term LCH in 1987. The incidence of LCH is 5.4 per million. It may present any age but average onset of age is between 1-3 years with a male predominance. Though it may involve any organ head and neck is affected in about 55-73% cases.

In Bangladesh and India incidence were 10.6% and 10.4% respectively on 2018. At the same time worldwide incident was only 2%.

Fine needle aspiration cytology, MRI, CT scan, and histopathological examination of postoperative specimen of neck swelling, analyzed data presented by various tables, graphs and figures. Results:In the present series 50 cases of neck swelling were studied. Out of these 50 cases 19 were male and 31 were female. The male, female ratio was 1:1.63. Age range was 4 – 60 years with maximum frequency in the 4 decade with the 3 and 2 in the following suit. Most of the patient were poor. Clinical, cytological and histopathological diagnosis were available in all the cases. The three sorts of diagnoses were compared with each other. Histopathologically 12 cases were tubercular lymphadenopathy. Metastatic carcinoma and lymphoma 5 cases for each. Twelve were nodular goiter, 5 were thyroid carcinoma. Rest were benign, congenital and nonspecific inflammatory conditions. Correct diagnosis were made by FNAC in 45 cases. In the rest 5 cases smear were unsatisfactory in 2 cases and gives inconclusive result, remaining 3 were follicular neoplasm and no definitive result were made which were subsequently diagnosed by histopathological examination as a follicular adenoma in 1 and follicular carcinoma in 2. Sensitivity of FNAC in the diagnosis of neck masses were found 91% for tuberculosis, 100% for metastatic carcinoma also for salivary gland tumour. In case of nodular goiter sensitivity was 92%. But it is only 60% sensitive in case of thyroid malignancy, as FNAC can not demarcate clearly between follicular adenoma and follicular cell carcinoma. But its accuracy in diagnosing papillary cell carcinoma of thyroid was 100%.
