Abstract Background: Understanding middle ear anatomy, in addition to endoscopic surgical skill acquisition, is an arduous task. Mastering 3-dimensional conceptualization and surgical dexterity may take many years. The coronavirus pandemic has made training difficult and complicated due to social distancing and risk of aerosolized viral spread in cadaver dissection. In this study we suggest a smartphone-based endoscope ovine head cadaveric dissection which is a simple, safe, and affordable training model for residents as an initial step in otologic endoscopic surgery training.Methods: A stepwise depiction of endoscopic ovine middle ear surgery; from cadaver and equipment acquisition, setting preparation, to surgical explanation and procedural steps. Results: The smartphone-based endoscopic otological ovine dissection model provides a low-cost, easily accessible and easily deployable training model for the novice surgeon world-wide. This model permits the novice surgeon a comprehensive anatomical understanding, middle ear proprioception, as well as a "safe" practicing model for diverse middle ear procedures. Conclusions: The ovine cadaver otological smartphone-based endoscopic surgery training model is an affordable, easy, reproducible, and transportable model, which makes it an ideal model from implementation in both low-middle and high-income countries.

Objective To assess outcomes of transcanal endoscopic ear surgery (TEES) for congenital cholesteatoma. Study Design Case series with chart review of children who underwent TEES for congenital cholesteatoma over a 10-year period. Setting Three tertiary referral centers. Methods Cholesteatoma extent was classified according to Potsic stage; cases with mastoid extension (Potsic IV) were excluded. Disease characteristics, surgical approach, and outcomes were compared among stages. Outcomes measures included residual or recurrent cholesteatoma and audiometric data. Results Sixty-five cases of congenital cholesteatoma were included. The mean age was 6.5 years (range, 1.2-16), and the mean follow-up was 3.9 years (range, 0.75-9.1). There were 19 cases (29%) of Potsic stage I disease, 10 (15%) stage II, and 36 (55%) stage III. Overall, 24 (37%) patients underwent a second-stage procedure, including 1 with Potsic stage II disease (10%) and 21 (58%) with Potsic stage III disease. Eight cases (12%) of residual cholesteatoma occurred. One patient (2%) developed retraction-type (“recurrent”) cholesteatoma. Recidivism occurred only among Potsic stage III cases. Postoperative air conduction hearing thresholds were normal (<25 dB HL) in 93% of Potsic stage I, 88% of stage II, and 36% of stage III cases. Conclusion TEES is feasible and effective for removal of congenital cholesteatoma not extending into the mastoid. Recidivism rates were lower with the TEES approach in this large series than in previously reported studies. Advanced-stage disease was the primary risk factor for recidivism and worse hearing result. As minimally invasive TEES is possible in the youngest cases, children benefit from early identification and intervention.

Middle ear tumors are relatively rare, and among them, the diagnoses of middle ear lesions originating from cartilage-like tissue are even rarer. Use of transcanal endoscopic ear surgery (TEES) has increased in recent years because of its advantages, such as clear visual field and minimally invasive procedure. Here, we report a middle ear mass originating from cartilage-like tissue treated with TEES. A 62-year-old woman presented with progressive right-sided hearing loss. A white mass was revealed through the tympanic membrane, and pure-tone audiometry detected a mean 50.0 dB conductive hearing loss. Computed tomography showed a mass in the tympanic cavity. TEES was performed for diagnosis and treatment. A white translucent tumor was observed intraoperatively, and it was completely resected. Histopathological examination confirmed the diagnosis of a mass originating from degenerated cartilage-like tissue. To the best of our knowledge, this is the first study of a middle ear mass originating from cartilage-like tissue treated with TEES. TEES with its clear visual field and precise techniques was beneficial in treating the middle ear lesions circumscribed in the tympanic cavity.

<p><strong>Background:</strong> Objectives were to compare outcomes, intra operative visualization and operative time duration in endoscopic assisted vs conventional middle ear and mastoid surgery.</p><p><strong>Methods: </strong>This prospective comparative study was conducted in 50 patients; among them 25 cases were of endoscope assisted middle ear surgery and 25 cases with conventional microscopic middle ear surgery. A 4 mm diameter, 18 cm long rigid, zero-degree endoscope and operating microscope was used. Primary outcomes include mean average pre and post operative air-bone (A-B) gap, hearing thresholds, intra operative visualization and duration of surgery.<strong></strong></p><p><strong>Results: </strong>Mean A-B gap closure for endoscopic assisted tympanoplasty was 12.76±6.00 dB, while it was 8.38±5.78 dB for non-endoscopic assisted tympanoplasty. The results were comparative. Mean intra-operative time duration for endoscopic assisted tympanoplasty was 70.23±4.17 min, while it was 77±9.80 min for non-endoscopic assisted tympanoplasty with statically significant difference between both groups (p=0.03). Graft uptake rate for endoscopic assisted tympanoplasty was 92.31% while it was 84.62% for non-endoscopic assisted tympanoplasty. Residual cholesteatoma remnant on endoscopy was found in 43.66% cases out of 12 mastoidectomy cases performed via endoscopic assistance.<strong></strong></p><p><strong>Conclusions: </strong>The endoscope can be successfully applied to ear surgery for most of the ear procedures with a reasonable success rate both in terms of perforation closure and hearing improvement and with minimal exposure. Wide-field zero, 30 or 70° endoscope sallow visualization of hidden anatomic spaces and working around corners i.e., epitympanum, hypotympanum and retro tympanum for safe removal of cholesteatoma.</p>

Objectives: We evaluated the closure rate after fat-graft myringoplasty (FGM) of perforations differing in size and location. We explored whether patient’s factors and the FGM surgical technique influenced surgical outcomes. Methods: We retrospectively studied patients with tympanic membrane perforations who underwent FGM from March 2015 to March 2019. All procedures were performed by a single senior surgeon at our tertiary hospital. The patients who followed-up for at least 6 months after surgery were enrolled. We recorded hypertension and diabetes status, age, any prior ear surgery, any calcific plaques adjacent to the perforation, and perforation size and location. Results: A total of 150 patients were enrolled. Our success rate of FGM was 90%. Hypertension, diabetes, prior ear surgery history, and eardrum calcific plaques did not affect the surgical outcomes. There was no statistical difference in the surgical success rate according to the size (< 50%) or location of perforation. The closure rate was 97.2% in patients aged 1660 and 87.5% in patients aged > 60, respectively. However, FGM was successful in only two of six children (33.3%) aged ≤ 15 years, thus significantly less than in the other groups. Conclusion: FGM is a fast, safe, and efficient method for repairing tympanic membrane perforation. The surgical outcome is not significantly affected by underlying disease, perforation size or location, or by the condition of the tympanic membrane or older age. However, it may be poor in children with dysfunctional Eustachian tube.
