Observation of the efficacy of endoscopic myringoplasty with homoplastic amniotic membrane / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To explore the clinical effectiveness of endoscopic myringoplasty with homoplastic amniotic membrane.@*METHOD@#A retrospective study in 43 patients underwent endoscopic myringoplasty with homoplastic amniotic membrane was observed at the wound healing of tympanic membrane perforation and the hearing improve-threshold audiometry in 43 patients after surgery.@*RESULT@#The tympanic membrane's perforation healing rate was 95.3% (41/43), and air conduction threshold audiometry in language frequency improved average 10 dB. The follow up was 1--4 years, and no recurrence or complications had occurred.@*CONCLUSION@#The endoscopic myringoplasty could be able to simple myringoplasty whose air conduction threshold audiometry in language frequency was less than 40 dB. It could be used to repair not only the central perforation in tympanic membrane, but also the marginal perforation which has residual tympanic membrane in most of the regional. Human amniotic membrane is an ideal materials for repair of tympanic membrane.
