[Application of fascia of the temporal muscle and cartilage of the auricular tragus in myringoplasty in children].

[Article in Serbian]

Abstract

INTRODUCTION:

Perforation of the tympanic membrane in children may be the cause of recurrent middle ear infection and loss of hearing.

OBJECTIVE:

The aim of this study was to analyze the application of different reconstructive materials in surgical technique myringoplasty.

METHODS:

We performed 88 myringoplasties due to auricular tragus perforation in 76 children (aged 4 to 16 years, mean 11.9 years) from July 2001 to July 2009. Age, gender, size and the site of perforation, status of the contra lateral ear, underlying cause of the perforations, surgical technique, preoperative and postoperative hearing levels and postoperative complications were recorded and analyzed. In performing myringoplasty we used fascia of the temporal muscle and cartilage of the auricular tragus.

RESULTS:

In 43 (48%) patients we used fascia of the temporal muscle and in 45 (52%) cartilage of the auricular tragus. Graft success was defined as an intact eardrum at 12 months postoperatively and improvement in the perception of air-bone gap of 10 dB, which we recorded in 73 (83%) cases. Re-perforations were recorded in 12 (13%) patients, of whom in 8 (18.6%) cases we used the temporal fascia and in 4 (9.3%) cases a tragal cartilage. Retraction of the tympanic membrane was recorded in 3 (4%) cases with the temporal fascia.

CONCLUSION:

Myringoplasty is a reasonably successful method with good functional results in pediatric patients. Risk factors of surgical failure are young age, the size of auricular tragus perforation and pathological conditions of the contra lateral ear. The tragal cartilage gives better results in cases with bilateral perforations because the possibility of retractions and re-perforations is lower. Relatively small number of patients is probably the reason that, exept for young age, differences between the two groups did not reach the level of statistical significance.
