A clinical research of endoscopic myringoplasty with modified sandwich technique / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To explore the curative effect of endoscopic myringoplasty with modified sandwich technique.@*METHOD@#Endoscopic myringoplasty was performed with modified sandwich technique for traumatic perforation of tympanic membrane and chronic suppurative otitis media (simple type) of 43 patients.@*RESULT@#All the perforating tympanic membranes were repaired successfully in one time. Six months after the operation, 1 case was out of follow-up and 2 cases were failed one got a small perforation when the transplantation shifted and the transplantation of the other one was lost because of infection. The closure rate of tympanic membrane perforations was 95.2%. The air-bone gap of speech frequency of 28 ears increased by > 15-20 dB, 8 ears were enhanced by 10-15 dB, while 6 ears (including 2 failed cases) without improvement. The acoustic immittance test showed that "Type A", "Type As", "Type Ad", "Type B" and "Type C" tympanogram were in 30 ears,12, 4, 6 and 4, respectively.@*CONCLUSION@#The endoscopic myringoplasty with modified sandwich technique has the advantages of simple operation, better security, less trauma and better efficacy, and it is worth popularizing.
