“…The perforation closure rate was 80%, and postoperative improvement of ABG was 7 dB. Furukawa [4] reported 25 ears that underwent transcanal endoscopic myringoplasty; a perforation closure rate of 84.0% was obtained, with only one case of reperforation. The improvement in ABG was 10.3 dB.…”

“…However, despite providing direct exposure, microscopes require frequent adjustment and may still not be sufficient when encountering protruding structures, particularly the anterior wall. In a study conducted by Furukawa et al [4] , the circumference of the perforation could not be confirmed with a microscope before denuding in 12.0% of cases. Furthermore, the entire perforation was not visible in 20.0% of cases after refreshing the edges.…”

OBJECTIVE:Tympanoplasty is a common surgery for chronic otitis media. We analyzed the results of endoscopic and microscopic approaches for type 1 tympanoplasty in patients with simple chronic otitis media. MATERIALS and METHODS:We evaluated the records of 95 patients (100 ears) who underwent type 1 tympanoplasty from 2011 to 2014. Group 1 underwent tympanoplasty with a microscopic approach (50 ears), and Group 2 underwent tympanoplasty with an endoscopic approach (50 ears). The epidemiological profiles and postoperative results, including hearing gain, duration of surgery, perioperative nausea or vomiting, and graft success rate, were reviewed. RESULTS:The epidemiological profiles and preoperative hearing status were similar in both groups. Postoperatively, both groups had equal improvements in hearing and air-bone gap as well as equal perforation rates. However, the endoscopic group suffered less perioperative nausea or vomiting and had a shorter operative time. CONCLUSION:The endoscopic approach for tympanoplasty offers superior visualization and shorter operative time than conventional surgery, in addition to equal hearing outcomes and perforation rates. Furthermore, observations of fewer tissue injuries, better cosmetic outcomes, and lesser perioperative nausea and vomiting suggest that the endoscopic approach is a better choice for surgery.

“…With endoscopes, the line of sight can be moved closer to the surgical field, allowing more complete surveillance. In addition, endoscopes allow visualization around structures, which is not possible with a conventional microscope and is greatly augmented with angled endoscopes [6,[13][14][15][16] . Accordingly, an increasing number of ear-surgeons nowadays considers otosclerosis to be a suitable disease for endoscopic stapes surgery due to the fact that the endoscopic approach offers excellent visualization of middle ear structures and recesses, mainly the oval window niche, stapes anterior crus, and its suprastructure [5,6,[17][18][19] .…”

OBJECTIVE:Comparing the endoscopic and microscopic approaches in stapes surgery, and establishing the surgical approach that allows better results in terms of visualization of the middle ear structures and aids assistant's training. MATERIALS and METHODS:Twenty-one residents from the first to the fifth year of training in Otolaryngology were enrolled in this prospective study. A questionnaire specifically designed to investigate the understanding of middle ear anatomy, the surgical steps, and a personal opinion about endoscopic stapes surgery was submitted to each resident. RESULTS:Statistical differences between the endoscopic and microscopic approaches were evident about identification of stapes and long process of the incus (p=0.03) and stapes footplate and the oval window (p=0.03). No substantial difference between the two surgical approaches emerged regarding the visualization of the tympanic membrane and the other middle ear structures (p>0.5). A substantial difference in favor of the endoscopic approach emerged regarding the identification of the hole creation in the footplate of the stapes. CONCLUSION:Endoscopic stapes surgery could favor an easier understanding of the surgical technique for assistants in training with little knowledge of the anatomy and surgical steps.

“…Hearing thresholds including air conduction and bone conduction were measured at 0.5, 1.0, 2.0 kHz, and the pure tone averages were calculated. TM perforation size was expressed as a percentage of the entire TM area using Image J software (National Institutes of Health, Bethesda, MD, USA) 6 . X-ray mastoid was done to know the cellularity of mastoid.…”

Chronic otitis media is the chronic inflammation of mucoperiosteal lining of the middle ear cleft characterized by ear discharge, a permanent perforation of the tympanic membrane and impairment in hearing. It is one of the most common ear diseases encountered in developing countries due to poor socio-economic standards, poor nutrition, lack of health education and unhygienic habits. Other causes of tympanic membrane perforation include trauma,blast injury etc. According to the American Academy of Ophthalmology and Otolaryngology Subcommitee on conservation of Hearing 1965 definition Tympanoplasty is ''a procedure to eradicate disease in the middle ear and to reconstruct the hearing mechanism with or without tympanic membrane grafting"1 . The term Tympanoplasty was introduced in 1953 by Wullstein to describe surgical techniques for reconstruction of the middle-ear hearing mechanisms that had been impaired or destroyed by chronic ear disease 2 . Tympanoplasty can be considered the final step in the surgical conquest of the conductive hearing loss and represents the culmination of over 100 years of evolution of surgical procedures on the middle ear to improve hearing. The surgical application of the operating microscope,first by Nylen 3 in 1921 as a monocular instrunment , and then by Holmgren,who introduced the binocular operating microscope in 1992,was an important advance destined to play an increasing role in the perfection of fenestration ,stapes operations and tympanoplasty . With the advent of the rigid endoscopes for sinus surgery, its extended applications in other fields have emerged. Mer and colleagues introduced the middle ear endoscopy 4 . Since then endoscopes are increasingly used for various middle ear surgeries. 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 5 . In the surgical repair of tympanic membrane perforations several variables come into play such as size of perforation, overhang, eustachian tube function, state of the mucosa, wound healing, degree of pneumatization etc. Aims and Objectives:-The objective was to determine merits and demerits of the endoscope as compared to the microscope in tympanoplasty type-1 surgery and to compare the results of both groups in terms of the duration of surgery, graft success rate and the post operative hearing gain.Corresponding Author:-Smruti Swain.
