Pediatric lateral graft tympanoplasty A review of 78 cases.

The optimal timing and technique for repairing chronic tympanic membrane (TM) perforations in pediatric patients remains controversial. The objectives are to determine the surgical and hearing outcomes of pediatric lateral graft tympanoplasty at a tertiary teaching hospital. A retrospective review was conducted for pediatric lateral graft tympanoplasties performed for chronic TM perforations by a single surgeon over a four-year period. Primary and secondary outcomes were graft failure rate and hearing outcomes, respectively. 78 cases were analyzed. The mean age at time of surgery was 10.3 years (range 5-18 years). Mean follow-up was 11.0 months; 27 patients had follow-up >1 yr. Most patients were non-syndromic (85.9%), had a history of bilateral Eustachian tube dysfunction (ETD) (59%) and presented with marked myringosclerosis (73.1%). Thirty-three percent of cases were revision tympanoplasties. A learner surgeon (resident or fellow) was present in 89.7% of cases. Successful closure of the TM was achieved in 97.4% (76/78) of cases and 92.6% (25/27) of cases with >1-year follow-up. No obvious difference in graft failure was noted with regards to age at time of surgery, perforation size, history of bilateral ETD, presence of a learner surgeon, myringosclerosis, presence of syndromic features, or history of prior tympanoplasty. Ninety-one percent of patients either improved hearing or preserved their conductive hearing deficit. Poorer hearing outcomes were only associated with post-operative blunting. Pediatric lateral graft tympanoplasty is effective in repairing chronic perforations with excellent hearing outcomes. Common quoted predictors of surgical outcome such as age at the time of surgery, syndromic features, history of previous myringoplasty, perforation size, and ETD dysfunction were not associated with graft failure in our series.
