Failures in myringoplasty.

E Vartiainen, J Kärjä, S Karjalainen

    Archives of Oto-Rhino-Laryngology
    |January 1, 1985
    PubMed
    Summary

    Graft failure in myringoplasty, including re-perforations and adhesive eardrums, is influenced by factors like infection and perforation size. Surgical techniques and ear condition impact outcomes.

    Area of Science:

    • Otolaryngology
    • Surgical Outcomes Research

    Background:

    • Myringoplasty is a common surgical procedure to repair tympanic membrane perforations.
    • Graft success rates and potential complications require thorough investigation to optimize patient outcomes.

    Purpose of the Study:

    • To analyze the failure rates and causes of graft failure in myringoplasty.
    • To identify pre-operative and surgical factors influencing graft take and complications such as re-perforation and adhesive eardrums.

    Main Methods:

    • Retrospective analysis of 417 myringoplasty procedures.
    • Categorization of failures into re-perforations and adhesive eardrums.
    • Evaluation of pre-operative factors (ear condition, perforation site) and surgical techniques (underlay, overlay, sandwich).

    Main Results:

    • Overall re-perforation rate was 10.6%, with half occurring early post-operatively due to graft necrosis or anterior margin blunting.
    • Infection was the primary cause of late re-perforations.
    • Larger perforations had higher re-perforation rates compared to smaller ones.
    • Adhesive eardrums occurred in 5.5% of cases, associated with pre-operative infection and specific surgical conditions.
    • Lateralization of the graft was rare (0.5%), observed only with the sandwich technique.

    Conclusions:

    • Graft success in myringoplasty is significantly affected by post-operative infection and the size of the tympanic membrane perforation.
    • While certain surgical techniques and pre-operative factors do not appear to influence graft take, careful management of infection and perforation size is crucial for successful myringoplasty outcomes.
