Abstract:
Objective To investigate the application and the effects of individualized hollow resin plugs in the prevention of external auditory canal stenosis after canaloplasty of external auditory meatus for microtia patients . Methods The clinical data of 65 patients (68 ears) with microtia and aural atresia hospitalized in our department from January ,2006 to December ,2015 were summarized .Otoplasty of external ears and canaloplasty of external auditory meatus were operated on all patients under general anesthesia .Thigh flap transplantation was lined in the bony canal .One month later ,individualized hollow resin plugs were made and worn for 6 to 12 months ,and fol-lowed up for 1～2 years .Results The shapes of the reconstructed auricles were satisfactory .Sixty-four ears with wide external auditory canal openings were recorded in 68 ears .Preoperative hearing was 70 .45 ± 5 .5 dB HL ,and postoperative hearing was 55 .55 ± 5 .2 dB HL .Their hearing was not affected .External auditory canal restenosis occurred in 4 ears .Conclusion The individualized hollow resin plugs do not affect the hearing in use ,and can effec-tively prevent the restenosis of the external auditory canal after microtia reconstruction .
