ESQUIVEL C, Patricia; NASER G, Alfredo  y  BUSTAMANTE Y, Carolina. Tympanoplasty in children: 10 years' experience at the Clinical Hospital of Universidad de Chile. Rev. Otorrinolaringol. Cir. Cabeza Cuello [online]. 2006, vol.66, n.1, pp.7-12. ISSN 0718-4816.

The objective of this paper was to know the anatomic and audiological results of tympanoplasties, evaluate prognostic factors associated to the surgery and compare the results with published literature. For this purpose the clinical file cards of patients under 14 years of age operated at the Clinical Hospital of Universidad de Chile between 1994 and 2003 were reviewed, in whom tympanoplasty without mastoidectomy was practiced. Only those patients who were subject to pre and postoperatory audiometric control were included, and with a minimum clinical follow-up six months postoperatory. Work was conducted with 41 ears operated, registering age, sex, type of perforation, type of surgery (approach passage, type of gran and placement of gran), anatomical result, auditive result and postoperatory complications. The average age was 8,3years (range between 4 and 14years). There were no differences by gender. The anatomic result amounted to 90% and the auditive Improvement was significant In 78% of the cases. No relation was found between the approach passage, type of graft and its placement technique and the postoperatory success. A higher percentage of anatomic and auditive success was observed in children under 8 years of age (p <0,05). The results of the study agree with the bibliography, where age is the sole factor with an influence on the post-surgical success. The best results were obtained in children under 8 years of age, this anatomical result being even better than those observed for the general population
