INTRODUCTIONMyringoplasty is a surgical procedure which is confined to the drum head without manipulation of the ossicles or middle ear. Tympanoplasty is the surgical procedure which includes the manipulation of tympanic membrane and eradication of disease from the middle ear if present, if it is done in conjunction with manipulation of the ossicles it is known as tympanoossiculoplasty. Surgery that includes manipulation of mastoid along with tympanoplasty is known as tympanomastoidectomy. The development of tympanoplasty techniques led by incidental and inspirational contribution from surgeons all over the world. Specialized instruments like the ocular magnifying loops and the operating microscope opened up a new dimension to otology surgery. The newest technique of performing tympanoplasty is the endoscopic tympanoplasty. Initially endoscopes were used for diagnostic and teaching purpose of tympanic membrane and ear canal. Mer and colleagues introduced middle ear endoscopy in 1967.1 From then, endoscopes are increasingly used for various middle ear surgeries. In recent years, many surgeons have adopted it for middle ear surgery as opposed to microscope assisted ear surgery. Transcanal endoscopic approaches of middle ear provide wide angled view for inspecting the anatomy of the middle ear and redefining of the ossicles, which allows a better understanding of the ligaments and folds of the middle ear and help to understand the physiology of different spaces.2 The aim of otology surgeons at ABSTRACTBackground: Aim of the study was to evaluate the merits and demerits of endoscopic tympanoplasty compared to conventional microscopic tympanoplasty.Methods: This prospective comparative study was carried out between October 2015 to September 2016 in our otolaryngology department, for a period of 12 months. Total of 40 patients who fit into inclusion criteria, underwent endoscopic tympanoplasty under local anaesthesia with sedation. All laboratory preoperative testing was done; hearing evaluation was done with audiometry. Postoperative follow up was done at 2 nd and 3 rd month's period, graft status and hearing evaluation with PTA for all four frequencies 500, 1000, 2000 and 4000 Hz with air conduction and bone conduction thresholds were recorded. Results: Out of 40 patients, 16 (40%) were males, and 24 (60%) were females, there were 21 (52.5%) cases had moderate perforation, 15 (37.5%) cases had large perforation and 4 (10%) cases had subtotal perforation. Average time taken was of around 1hour and 30minutes, range was (70-140min.). All patients were evaluated for graft status, hearing gain and cosmetic results. Out of 40 patients, 35 (87.5%) patients had successful graft uptake, 2 (5%) patients had graft infection and 3 (7.5%) patients had residual perforation seen postoperatively. Conclusions: Use of endoscope not only serves as a great teaching tool, but also helps to visualize the middle ear anatomy and pathology intraoperatively with minimal soft tissue manipulation better cosmesis and reduced postoperative morbi...

<p class="abstract"><strong>Background:</strong> Dacryocystorhinostomy is the current surgical modality of treatment preferred for patients with nasolacrimal duct obstruction. Both external and endonasal endoscopic approaches have been in practice with their own merits and demerits. Since the invention of endoscopes, endoscopic DCR is preferred for its scarless, minimally invasive technique and many modifications have been done over years like placement of silicon stents to reduce recurrence.</p><p class="abstract"><strong>Methods:</strong> In our study we evaluated 70 patients with epiphora with obstruction in nasolacrimal duct, Fresh cases and revision cases who had undergone either external and/ endoscopic DCR without stent were included. All patients underwent endoscopic dacryocystorhinostomy (DCR) with silicon stent placement. Patients were followed postoperatively for a period of 6 months to 3 years.  </p><p class="abstract"><strong>Results:</strong> The results were compared with that of external DCR and endoscopic DCR without stent. In our study we found that, endoscopic DCR with silicon stent had less chances of recurrence and synechiae formation. Results at 3 years follow up have been good with 95.7% patients relieved of symptoms completely.</p><p class="abstract"><strong>Conclusions:</strong> Endoscopic DCR is a cost effective and a safe alternative for External DCR in patients with nasolacrimal duct obstruction. We found that endoscopic DCR with stenting had several advantages over more conventional external approach.</p>

<p class="abstract"><strong>Background:</strong> To compare the efficacy between fat graft (FG) and temporalis fascia (TF) graft in tympanic membrane perforations larger than 4mm size or involvement of &gt;25% of tympanic membrane.</p><p class="abstract"><strong>Methods:</strong> This prospective study was carried out during December 2015 to January 2016, for a period of 13months at our Otolaryngology Department. All study patients, who fit into inclusion and exclusion criteria, were divided into two groups according to the type of graft material taken. In group- 1temporalis fascia (TF) graft was taken while in group- 2 fat graft (FG) was taken. An evaluation of hearing was done with full Audiometric and Eustaschian tube function testing. All laboratory preoperative testing was done. Postoperative follow up was done at 2^nd, 3^rd and 5^th month’s period and sos, graft status and hearing evaluation with PTA for all four frequencies 500, 1000, 2000 and 4000 Hz with air conduction and bone conduction thresholds were recorded and compared with preoperative PTA records in both groups.  </p><p class="abstract"><strong>Results:</strong> In TF group total 24 (80%) patients had graft uptake, 4 (13.3%) patients had residual perforation and 2 (6.6%) patients had graft failure due to postoperative infection. In FG group total 16 (53.3%) patients had graft uptake, 6 (20%) patients had graft medialised and necrosed, 6 (20%) patients had residual perforation and 2 (6.6%) patient had graft rejection due to postoperative infection. Graft uptake rate in group 1 was 80% while in group 2 was 53.3%. Mean preoperative ABG in TF group was 25±17 dB and mean postoperative ABG was 10±02 dB, in fat graft technique mean preoperative ABG was 25±13 dB and mean postoperative ABG was 16±15 dB. Fat graft technique is simple, quick and minimally invasive. It doesn’t require middle ear manipulation.</p><p><strong>Conclusions:</strong> There is no ideal material for tympanic membrane repair but for moderate to large perforation temporalis fascia graft is better than fat graft in terms of healing and hearing outcomes but considering morbidity fat gives less morbidity. </p>

Background: The objective of the study was to evaluate the criteria for diagnosing allergic fungal rhinosinusitis and to maintain permanent drainage and ventilation, while preserving the integrity of the mucosa. Methods: This is a prospective study of 50 patients with allergic fungal sinusitis with or without polyposis all of whom were treated with endoscopic debridement. Mucous sample collection, nasal secretion culture, surgical specimen handling, and histological evaluation of surgical specimens are described. All patients treated with endoscopic sinus surgery, debridement, post-operative use of steroids and antifungal therapy. Results: Fungal mucin was found in all 50 cases, histology and fungal cultures confirmed the diagnosis. Out of 50 patients, 29 were females and 21 were males, with a mean age of 32 years. The most common symptom was nasal discharge 41 (82%) cases, nasal obstruction in 38 (76%) cases, headache and facial pain in 32 (72%) cases, 7 (14%) patients had bronchial asthma. Symptoms of nasal obstruction and nasal discharge were improved in 46 (92%) cases. All preoperative versus postoperative changes in AFRS associated complaints reached statistical significance of p value <0.001 except in patients with asthma. Conclusions: Comprehensive management with endoscopic sinus surgery, oral steroids and antifungals reduces the recurrence or need for revision surgery. Long term follow up is very important.
