JIN Lanlan,ZHOU Qinshuang,FANG Lucheng, et al. The curative effect of revision operation for otitis media under endoscopic ear surgery[J]. JOURNAL OF WEZHOU MEDICAL UNIVERSITY, 2021, 51(5): 409-412.
Abstract：Objective: To investigate the safety and efficacy of revision operation for otitis media under endoscopic ear surgery. Methods: A retrospective analysis of 24 patients who underwent otitis media re-correction surgery under otoscope from February 2016 to February 2019. We analyzed the time of surgery, results of hearing test 6 months before and 6 months after surgery, tympanic membrane healing and tympanic nerve injury. Results:The operation time was (138.4±27.6)min, the preoperative air-guided hearing 500, 1 000, 2 000, 4 000 Hz was(53.54±7.20)dB nHL, and the air-bone conductance difference 500, 1 000, 2 000, 4 000 Hz was (32.08±6.41)dB nHL. The hearing guide 500, 1 000, 2 000, 4 000 Hz was (34.04±7.58)dB nHL, and the air-bone conduction difference 500, 1 000, 2 000, 4 000 Hz was (12.29±7.27)dB nHL. There was significant difference in hearing before and after surgery. All patients had good tympanic membrane transplantation and complete tympanic membrane transplantation 6 months after the surgery. Intra-operative exploration of the tympanic nerve was not observed in 8 cases. The tympanic nerve was disconnected in 6 cases due to adhesion separation, and it was intact in 10 cases.Conclusion: With wide angle and clear field of vision under otoscope, corrective surgery after otitis media is feasible. However, compared with the first operation, due to local scars and adhesions, the corrective surgery is more complicated than the initial surgery, and the tympanic nerve is prone to damage. Surgeons need to keep improving their surgical skills to achieve better practical hearing after surgery.
