Tympanoplasty on only-hearing ears is controversial but feasible. Careful surgical selection and technique, particularly myringoplasty for chronic otitis media, can yield positive outcomes while preserving hearing.

Area of Science:

  • Otolaryngology
  • Surgical Innovation
  • Auditory Health

Background:

  • Tympanoplasty on only-hearing ears is a rare procedure, comprising 0.68% of middle ear surgeries.
  • Indications for operating on ears with unique hearing status remain debated.
  • This study evaluates outcomes in patients undergoing tympanoplasty with contralateral hearing loss.

Purpose of the Study:

  • To assess the efficacy and safety of tympanoplasty in patients with only one hearing ear.
  • To analyze surgical outcomes based on the underlying middle ear pathology.
  • To provide recommendations for surgical indications and techniques in these specific cases.

Main Methods:

  • Retrospective analysis of 11 patients who underwent tympanoplasty on their only hearing ear between 1986 and 1994.

  • Patients included those with cholesteatoma (5), chronic otitis media (5), and cholesterin granuloma (1).
  • Postoperative hearing was evaluated using Otology Japan criteria (1987); graft success was determined by dry ear status.

    • Main Results:

    • Postoperative hearing results were available for 9 patients (81.8%), with 3 showing improvement, 7 no significant change (within 5 dB), and 1 experiencing a 10-15 dB deterioration.
    • All operated ears remained dry post-surgery, indicating successful graft take.
    • The mean age of patients was 47.6 years, with a mean follow-up of 2 years and 7 months.

    Conclusions:

    • Tympanoplasty on only-hearing ears can be performed with a dry ear outcome.
    • Specific recommendations include standard tympanoplasty for cholesteatoma and myringoplasty for chronic otitis media.
    • Extreme surgical caution and surgeon expertise are paramount for all patients undergoing this procedure.
