Summary

Most tympanic membrane perforations heal spontaneously within 10 months. Large, central, or kidney-shaped perforations heal less often and may require surgery.

Area of Science:

  • Otolaryngology
  • Trauma Surgery

Background:

  • Tympanic membrane perforations can result from blast injuries.
  • Understanding spontaneous healing rates is crucial for managing these injuries.

Purpose of the Study:

  • To evaluate the spontaneous healing rate of tympanic membrane perforations.
  • To identify factors influencing healing, such as time, size, and location.
  • To determine the optimal timing for surgical intervention.

Main Methods:

  • Retrospective analysis of 147 patients (210 ears) with tympanic membrane perforations.
  • Documentation of perforation characteristics (size, shape, location) and healing times.
  • Recording of surgical interventions performed (tympanoplasty, ossiculoplasty, mastoidectomy).

Main Results:

  • Spontaneous healing occurred in 74% of ears (155/210).
  • 62% (131/210) healed within 3 months; 69% (145/210) healed within 10 months.
  • Large, central, kidney-shaped perforations showed the lowest healing tendency.

Conclusions:

  • Spontaneous healing is common for tympanic membrane perforations.
  • Surgical intervention is recommended for perforations unhealed after 10 months.
  • Perforation characteristics influence the need for surgical repair.
