[A clinical research of endoscopic myringoplasty with modified sandwich technique].
OBJECTIVE
To explore the curative effect of endoscopic myringoplasty with modified sandwich technique.


METHODS
Endoscopic myringoplasty was performed with modified sandwich technique for traumatic perforation of tympanic membrane and chronic suppurative otitis media (simple type) of 43 patients.


RESULTS
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.


CONCLUSIONS
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.
