Research of Ear Endoscopic Type I Tympanoplasty——Single-institution Experiences in China

Abstract

Purpose: To assess outcomes of one-handed ear endoscopic Type I Tympanoplasty and summarize the experience. Methods: This study retrospectively analyzed 34 cases (23 females and 11 males) of one-handed ear Endoscopic Type I Tympanoplasty. Result: The mean values of air conduction threshold before and after surgery were 48.22+18.36dB HL and 34.34+19.83dB HL, respectively. The mean values of the air-bone gap before and after surgery were 23.60+12.18 dB HL and 11.05+6.62 dB HL, respectively. The results showed statistically significant differences in hearing improvement(P<0.05). Among 34 ears, 30 ears had effective hearing improvement. No vertigo, intracranial infection, suppuration, and any other postoperative complications occurred. Although 1 ear occurred tympanic membrane perforation again, all ears achieved dry. Conclusion: Ear endoscopic Type I Tympanoplasty with fewer complications and shorter surgery time were suitable for the chronic suppurative otitis media. Healing of the tympanic membrane and recovery of hearing level was ensured. However, the experience is still insufficient in China, so a large number of clinical workers need to exchange experience to promote the development of ear minimally invasive surgery.
