“…Thus, the deep anterior canal wall, anterior recess, anterior marginal perforations, sinus tympani, facial recess, hypotympanum and attic are visualized by rotating the angled scopes. [3][4][5][6] Very few studies have been conducted till date to correlate the outcomes of microscopic assisted and endoscopic assisted tympanoplasty. Hence this study is to compare the outcomes of tympanoplasty by conventional microscopic assisted method and endoscopic assisted method.…”

Background: The introduction of the operating microscope has significantly enhanced the outcome of tympanoplasty by improving the accuracy of the technique. The operating microscopy provides a magnified image in straight line; hence the surgeon can’t visualize the deep recesses of the middle ear in single operating field. This is overcome by use of rigid endoscope for tympanoplasty. In rigid endoscopy view is better but surgeons 2 hands are not free so manipulation here is difficult.Methods: 30 cases of safe CSOM from each group viz microscopic assisted (MES) & endoscopic assisted (EES) were selected operated by full cuff (superiorly based tympanomeatal flap technique) and compared for graft uptake, hearing improvement & complications.Results: Graft uptake rate was 93.33% in both groups. In our study the pre operative mean air bone gap of the patients was 37.23+5.79 db after surgery at 6 months came down to 17.17+3.31 db hence after calculating the mean air bone gap closure it came down to be 20.4+4.85. Which showed a significant improvement in the hearing (p value 1.493E-23 which is less than 0.05). 6.67% cases from both groups showed failure of graft uptake.Conclusions: The graft uptake, hearing improvement, Complications produced by each of the techniques in large, subtotal, and anterior moderate perforations by each technique is comparable i.e. both techniques have same results.

“…In an original article, "Endoscopic transcanal middle ear surgery" by Tarabichi M,92 % success in endoscopic transcanal success rate in graft closure was seen compared to microscopic surgery which was 80%. The advantage of endoscope was, it could be easily negotiated behind the narrow segment of external auditory canal and provides a panaromic, wide angled, magnifi ed view that allows the surgeon to "look around corners" unlike microscope 5 . One handed technique and loss of depth perception are the disadvantages of endoscopic technique 6 .…”

Background: Otoscopic procedure like tympanoplasty is one of the magic wands that an ear nose throat surgeon possesses to alleviate the suffering of a hearing impaired patient. Endoscopic trans-tympanic pop in technique is an alternative method where tympanic fascial graft is placed medial to tympanic membrane remnant through the perforation without elevation of tympanomeatal fl ap and angled endoscope is used to assess the ossicular chain. Objective: The study was done to compare the results of endoscope assisted trans-tympanic pop-in tympanoplasty with permeatal underlay tympanoplasty. Methods: The study is a prospective, longitudinal and experimental study conducted in Kathmandu Medical College Teaching Hospital from January 2016 to June 2016. A total of sixty-two patients, thirty-one in study and thirty-one in control group were present.The comparison was made in terms of success rate, decrease in taste sensation and time taken for the procedure. Data analysis was done by SPSS version 20. Categorical data were tested by Fisher Exact test and p-value of <0.005 was considered statistically signifi cant. Result: Among 62 patients, 55 had successful graft uptake (88.7% success rate). Hearing improvement was seen in 51 patients (88.25%). Regarding taste sensation 5 out of 62 had decrease in taste sensation after surgery (8%). Time taken was approximately 30 to 45 minutes (mean =44.1min) in endoscopic transtympanic pop-in type and 60 to 90 minutes (mean =73.8 min) in permeatal underlay type. Conclusion: We can conclude that endoscopic trans-tympanic pop-in tympanoplasty gives similar hearing and graft uptake result but with less time and greater ease as compared to permeatal underlay technique.

“…However, endoscopes have been used for observation and treatment of conditions in the areas that may be hard to visualize completely under the microscope. [6][7][8] In treatment of cholesteatoma, we have employed an endoscope combined with a microscope to minimize drilling, thereby preserving hearing and facial nerve called as "endoscopy assisted surgery". 10 Few reports have been published concerning stapes surgery that is entirely performed by endoscopy.…”

Background: To investigate whether endoscopic stapes surgery is safer and less invasive than conventional stapes surgery using an operating microscope.Methods: The subjects were 60 patients who were divided consecutively into group A undergoing microscopic stapedotomy and group B undergoing endoscopic stapedotomy. The procedures for endoscopic surgery were fundamentally the same as those for microscopic surgery, except for post aural incision used in some patients in microscopic group. The two surgical techniques were compared with respect to the operating time, approach, drilling of posterosuperior canal, manipulation of chorda tympani, visualisation of anterior crus, postoperative hearing, postoperative pain, and complications. Results: There were no differences of operating time or postoperative hearing between the endoscopic and microscopic groups. There was very little postoperative pain in the endoscopic group. Drilling at the posterosuperior part of the external auditory canal was less extensive in the endoscopic group than in the microscopic group. Visualisation of anterior crus of stapes was good in endoscopic group.Conclusions: Endoscopic stapes surgeries are technically feasible, safe and promising. The main advantages were: easy access, virtually no trauma to the chorda tympani nerve and excellent vision. The disadvantages were the lack of stereoscopic vision, having to work with one hand only and the learning curve.
