Objective: To further elucidate the role of balloon Eustachian tuboplasty (BET) in tympanoplasty, we conducted a study to compare the outcomes of tympanoplasty with and without BET for the treatment of chronic suppurative otitis media (CSOM) with obstructive Eustachian tube dysfunction (OETD). Study Design: Case control study. Setting: Tertiary referral center. Patients: A total of 70 ears diagnosed with CSOM (tubotympanic type) and OETD were included in this study. Thirty-five patients were prospectively enrolled for BET and tympanomastoidectomy between February 2018 and June 2019. Thirty-five control subjects were matched by sex and age and retrospectively enrolled for tympanomastoidectomy between July 2016 and January 2018. Interventions: BET, tympanomastoidectomy. Main Outcome Measures: The graft take rate, hearing levels, and Eustachian tube function test results. Results: The graft take success rate was higher in the BET group (80.0%; 28/35) than in the control group (68.6%; 24/35). However, the difference was not statistically significant. The average air-bone gap (ABG) improvement was 10.93 ± 7.70 dB in the BET group and 7.11 ± 8.08 dB in the control group, with a statistically significant between-group difference (p = 0.033). Conclusions: Our findings suggest that BET can objectively and subjectively improve the Eustachian tube function, with a slight but significant improvement in ABG despite the lack of a clinically significant improvement overall. However, it does not affect the graft take rate. In summary, BET could be used as an adjunctive procedure in the treatment of CSOM with OETD.

A glomangiopericytoma, or sinonasal type hemangiopericytoma, is a rare lesion which accounts for <0.5% of all sinonasal tumors. The mainstay treatment is wide excision. Instead of traditional open surgical approaches, such as midfacial degloving or lateral rhinotomy, we offer a case of 21-year-old male with diagnosis of glomangiopericytoma with skull base and intraorbital invasion and received navigation-assisted endoscopic excision of a glomangiopericytoma.

5, 1, 2, 3 kHz was 5.7 dB (std deviation 4.3) for the short-term group and 6.7 dB (std deviation 4.8) for the long-term group. The postoperative air-bone gap was less than 10 dB in 87% of the short-term group and 75% of the long-term group. Preoperative minus postoperative bone conduction averages (1,2,4 kHz) were 4.6 Hz (P less than 0.001)in the short-term group and 7.2 Hz (P equal to 0.01)in the long-term group corresponding to consistent overclosure of bone conduction values. CONCLUSIONS: The self-crimping shape-memory stapes prosthesis provides excellent short-term and long-term postoperative hearing improvements and closure of the air-bone gap. The self-crimping mechanism simplifies stapes prosthesis placement and may overcome the limitations of stapes prostheses requiring manual crimping.

Twenty-two patients had a dry ear and healthy lining of the mastoid cavity (85%). Two patients were lost in follow-up. Only two had persistent discharge from the ear. Even though the number of clinic visits decreased after the operation, this failed to achieve statistical significance. Twenty out of 26 patients returned the GBI (77%). The GBI showed a mean total benefit of ϩ27 (CI: 18-37), social benefit of ϩ 30 (CI: 18-42), and physical benefit of ϩ 26 (CI: 15-37). These results are comparable to other otological procedures that produce good improvement in the quality of life. CONCLUSIONS: Hong Kong flap is a good technique for management of chronically discharging mastoid cavity due to unhealthy lining. It also improves the quality of life for patients.
