Insights

Age does not affect hearing improvement after congenital aural atresia (CAA) repair. Both younger and older patients achieve similar audiometric outcomes and complication rates following primary CAA surgery.

Area of Science:

  • Otolaryngology
  • Audiology
  • Pediatric Surgery

Background:

  • Congenital aural atresia (CAA) is a condition that affects hearing development.
  • Surgical repair aims to improve audiometric outcomes.
  • The impact of patient age on surgical success in CAA repair requires further investigation.

Purpose of the Study:

  • To evaluate if age influences audiometric outcomes in patients undergoing primary congenital aural atresia repair.
  • To compare hearing improvements between younger and older patient cohorts.

Main Methods:

  • Retrospective chart review of 247 patients (262 ears) who underwent primary CAA repair between 2004 and 2020.
  • Audiometric outcomes including air-conduction PTA, bone-conduction PTA, air-bone gap, and speech reception threshold were analyzed.
  • Patients were stratified into younger and older groups using cutoff ages of 12 years and 8.5 years.

Main Results:

  • No significant difference in preoperative to postoperative improvement in air-conduction PTA, air-bone gap, or speech reception threshold was observed between younger and older patient groups, using both 12-year and 8.5-year cutoff ages.
  • Average hearing improvements ranged from 23.8 to 31.3 dB HL across all groups.
  • Revision surgery rates and complication rates were comparable between age groups.

Conclusions:

  • Congenital aural atresia repair offers significant audiometric improvement regardless of patient age.
  • The findings suggest that age is not a limiting factor for successful hearing outcomes in CAA repair.
  • Both younger and older individuals can benefit from surgical intervention for CAA.
