Myringoplasty without tympanomeatal flap elevation in children: A systematic review

Abstract

Objectives: Systematic review of the literature on myringoplasty techniques without tympanomeatal flap elevation in children.

Material and methods: A systematic review following PRISMA guidelines reported papers on patients under 18years of age undergoing myringoplasty for chronic tympanic perforation on a transcanal approach without tympanomeatal flap elevation. Tympanic closure rates and audiometric results were analyzed.

Results: Twenty studies were included. Nine reported the butterfly technique, using a microscope or endoscope, with closure rate of 82.3% (246/299), for perforations of various sizes. Ten reported the fat-plug technique, with closure rate of 86.8% (869/1001), mostly for perforations of less than one-third of the tympanum. Both techniques improved audiometric results. Morbidity was very low. The absence of chronic otitis or co-morbidities (contralateral otitis media with effusion, craniofacial malformations, Down's syndrome) implies that patient selection technique may be necessary to obtain the best results.

Conclusion: Fat-plug myringoplasty, for small perforations, and butterfly cartilage myringoplasty seem to be reliable procedures in selected patients, with low morbidity in children.
