“…18 Zöllner and Wullstein tried to improve ET function by using silk threads or later polyethylene tubes or drilling the bony tube via a middle ear approach. 18,19 In 1966, William F. House and coworkers introduced a eustachian tuboplasty via a middle fossa approach. 20 However, this method was discontinued due to its very invasive character.…”

“…A retraction pocket can develop when a poorly functioning eustachian tube or scutum defect exists, which results in the recurrence of cholesteatoma. To avoid this process, manipulations to make the eustachian tube orifice patent (6) or reconstruct the scutum with cartilage (7), bone (8), or alloplastic material (9) have been performed. However, these procedures have not been entirely successful.…”

Objective: To evaluate the surgical outcome in patients who have undergone mastoid and epitympanic obliteration technique. Study Design: Retrospective review. Setting: Tertiary care referral center. Patients: The study group included 151 patients with cholesteatoma who underwent mastoid and epitympanic obliteration technique. This technique was applied to cases who had a strong chance of recurrent retraction pocket and cholesteatoma formation, including those patients with an adhesive drum indicating poor eustachian tube function (n = 52) and patients with a destructive scutum (n = 68). Thirty-one patients had both an adhesive drum and a destructive scutum. Intervention: The connection between the mastoid cavity and the middle ear was blocked by obliterating the epitympanum and antrum with bone pate and the remaining mastoid cavity with abdominal fat. Main Outcome Measures: The postoperative drum state, the incidence of retraction pocket formation and cholesteatoma recurrence, the surgical complications of obliteration, and the hearing outcome. Results: In 114 of 151 patients (75.4%), the middle ear was well healed and well aerated. The retraction pocket formation or cholesteatoma recurrence did not develop in any subject. Postauricular skin depression was the most common complication of this technique (n = 31 [20.5%]). In three patients (2.0%), the bone pate used for obliteration was infected. Of the 56 cases who underwent a staged operation to regain their hearing, 37 resulted in a postoperative air-bone gap less than 20 dB hearing level. Conclusion: Mastoid and epitympanic obliteration is an effective option for preventing a retraction pocket and cholesteatoma recurrence in patients with a poorly functioning eustachian tube or a defective scutum, while preserving the same advantage of the canal wall up technique.

“…14 The obliteration technique that preserves the posterior ear canal wall has given better results than does the air reservoir technique, because the more air-filled spaces there are, the greater the probability of retraction pockets. [15][16][17][18] The EMO technique might be indicated in cases of cholesteatoma, COM with poor eustachian tube function, or adhesive otitis media, which almost exclusively have sclerotic mastoid cavities favoring obliteration with autologous materials such as auricular cartilage and bone chips. 5 Traditionally, CWD 50 Heo et al, Epitympanoplasty With Mastoid Obliteration mastoidectomy has also been indicated in these conditions.…”
