Determinants of failure in the reconstruction of the tympanic membrane: A case-control study

Introduction: The recurrence rate after tympanoplasty is variable between 0% and 50%. The causes of failure may be different and frequently interrelated, making the surgical choice difficult and the prognosis not always favourable.
