Objective: This study aimed to clarify the indications for elective surgica
l repair of unilateral aural atresia in children and to review the rates of
successful repair in the literature.
Data Sources: A search of the published English language literature, 1966-1
997, was conducted using the key words aural atresia.
Study Selection: Articles were selected on the basis of their inclusion of
the authors' indications for surgical repair of aural atresia or the inclus
ion of surgical series that showed outcomes.
Data Extraction: Articles reviewed in the review had to either provide spec
ific guidelines for surgical repair of unilateral aural atresia or provide
postoperative pure-tone averages, air-bone gaps, or speech reception thresh
olds.
Data Synthesis: The authors compiled the relevant data into summary tables
and extracted conclusions from these data.
Conclusions: Elective surgical repair of unilateral aural atresia should on
ly be attempted in children who meet specific anatomic criteria that predic
t that they are the most likely to benefit from the results of surgery. Oth
erwise, repair should be delayed until the age at which the patient can mak
e an informed decision, knowing the risks, benefits, and consequences of th
is difficult surgery. Parents and surgeons must have a realistic expectatio
n of the surgical results and the practiced benefit to be expected with a n
ormal, contralateral ear.
