OBJECTIVE: We wished to determine if the success of lateral graft tympanoplasty was affected by either size of perforation, previous underlay tympanoplasty, or patient age.
PATIENTS: A review was performed of patients who underwent lateral graft tympanoplasty by the senior author between March 2010 and July 2013 with patient number based on an a priori power analysis. Patient demographics, baseline clinical data, postoperative findings, and audiologic data were collected.
INTERVENTIONS: Lateral graft tympanoplasty.
MAIN OUTCOME MEASURES: The primary outcome was closure of perforation. The secondary outcome was change in air-bone gap.
RESULTS: Thirty patients were included with a mean follow-up period of 14 months. Closure of tympanic membrane perforation occurred in 93%. Closure was observed in 13 of 15 (87%) patients with perforations 50% or smaller and in all patients (15 of 15) with perforations larger than 50% (p = 0.48, Fisher's exact test). For revision cases, 8 of 9 (89%) were closed compared to 20 of 21 (95%) in primary tympanoplasty (p = 0.52). Perforations in adults and children were equally likely to be closed (10 of 11 children vs. 18 of 19 adults) (p = 1). The mean preoperative to postoperative air-bone gap improved from 24 ± 12 dB to 14 ± 8 dB (p = 0.0003, paired t test).
CONCLUSIONS: Lateral graft tympanoplasty has a high success rate for the closure of tympanic membrane perforations with a significant improvement in air-bone gap. There were no significant differences in success comparing small versus large perforations, primary versus revision tympanoplasty, or adults versus children.
