Abstract

BackgroundThis case series study is to evaluate the results of our technique for correction of congenital aural atresia. Seventeen patients were done from 2015 till 2018, 4 cases bilateral and 13 unilateral. Surgical canalization of congenital aural atresia with the same session reconstruction of the meatus and TM by split thickness graft (Autograft) was done. Follow-up is done weekly for 3 months then every 2 weeks for another 3 months, till we establish the formation of EAC. All cases were followed up for at least 1 year.ResultsAll patients have now established skin limned external canal. There is no facial nerve or dural or sigmoid injuries. Only one case TMJ was exposed during the surgical procedure. One case had postauricular wound gapping and another one was complicated after 1 year by stenosis. All patients improved subjectively in speech and language postoperatively except one case who has autism and still undertreatment.ConclusionCongenital aural atresia is a challenging surgery. Surgical canalization with the same session grafting of the drum and the formed cavity by split thickness skin graft is effective with minimal minute rate of complications and recurrence.

Highlights

This case series study is to evaluate the results of our technique for correction of congenital aural atresia
It represents 1 in 10,000 live births [1]. It involves abnormal development of the first pharyngeal cleft. It results in varied degrees of malformation that affects the ossicles, middle ear space, tympanic membrane (TM), bony and cartilaginous external canal, and pinna [2]
2- After anesthesia: we examine the patient to determine the site of Temporomandibular joint (TMJ), zygomatic arch, mastoid tip level, and atretic segment

Summary

Introduction

This case series study is to evaluate the results of our technique for correction of congenital aural atresia. Surgical canalization of congenital aural atresia with the same session reconstruction of the meatus and TM by split thickness graft (Autograft) was done. Congenital aural atresia is not an uncommon disorder. It represents 1 in 10,000 live births [1]. It involves abnormal development of the first pharyngeal cleft. It results in varied degrees of malformation that affects the ossicles, middle ear space, tympanic membrane (TM), bony and cartilaginous external canal, and pinna [2].
