Myringoplasty: is it worth performing in children?

OBJECTIVE

To evaluate the results of myringoplasty in children 4 to 14 years old at the time of surgery.

DESIGN

Retrospective analysis of case notes for 100 consecutive children who had myringoplasty in a teaching hospital serving as a primary care and referral center.

METHODS

Between March 1994 and March 1999, patients 14 years or younger at the time of surgery were identified by the computer database. There were 118 procedures performed in 100 patients (18 had a second procedure performed in the contralateral ear at a later date). Twenty-three patients were excluded because they underwent concurrent mastoid exploration, and 6 others because of inadequate follow-up, leaving 89 cases for analysis. Data from revision procedures were not included.

MAIN OUTCOME MEASURES

Graft success was defined as an intact eardrum at 12 months postoperatively and middle ear effusion signaled graft failure. Success in terms of hearing was defined as an improvement in perception of pure-tone thresholds of 10 dB or greater over 2 consecutive frequencies compared with the results of the preoperative audiogram.

RESULTS

Closure of perforation was achieved in 90% (80) of patients, but dropped to 88% (78) as 2 patients developed glue ear. Hearing improved in 64 patients (72%), deteriorated in 7 (8%), and remained unchanged in 18 (20%). There was no case of profound hearing loss.

CONCLUSIONS

The success rate of myringoplasty in children is comparable to that reported for adults. The incidence of middle ear effusion in grafted ears is not higher than that reported for nongrafted ears, and children who have had myringoplasty can be treated as safely with ventilation tubes as any other children.
