Objectives: To report results of pediatric tympanoplasty and to identify of prognostics factors of tympanoplastys in the pediatric population.
Methods: We undertook a retrospective study embracing a period of 4 years (2008 to 2011), which included children of the ages 5 to 14 that had gone through tympanoplasty type I (Portmann classification). Patients had a follow up of a minimum of 6 months. The analyzed variables in our study were: gender, age at which surgery was performed, contralateral ear status, size and etiology of membrane perforation, tympanometric volume and audiolometrical evaluation. Surgical failure was considered in the presence of new chronic otitis media or auditory worsening.
Results: We reviewed 109 tympanoplasties. Surgical success was found to be 68.8%. In this series we found that surgical failure was more frequent in females 36.4% (p= 0.08). We observed surgical failure, although without statistical significance, on the following situations: children under 7 years old, pathological contralateral ear, large perforations, perforations after acute otitis media and small tympanometric volumes.
Conclusions: Pediatric tympanoplasty can offer good chances of surgical success if the patients are carefully selected. In our study females have more probability of surgical failure.
