Congenital aural atresia.

Area of Science:

• Otolaryngology
• Surgical Innovation
• Pediatric Surgery

Background:

• Congenital aural atresia presents significant surgical challenges.
• Long-term surgical outcomes for various atresia types are crucial for patient management.

Purpose of the Study:

• To evaluate the surgical outcomes of congenital aural atresia over a 25-year period.
• To assess the efficacy of different surgical techniques in improving hearing and managing complications.

Main Methods:

• Retrospective analysis of 69 ears with congenital aural atresia.
• Surgical procedures included meatoplasty, canaloplasty, canaloplasty with struts, and mastoidectomy with stapediopexy.
• Outcomes assessed by hearing threshold improvement and complication rates.

Main Results:

• Eight percent of patients with partial or total atresia had hidden cholesteatomas.
• Temporary facial palsy occurred in 8% of cases; hearing improvement was abandoned intraoperatively in 8% due to anomalies.
• A hearing threshold of 20 dB or better was achieved in 30% of canaloplasty cases and 8% of mastoidectomy with stapediopexy cases.

Conclusions:

• Surgical management of congenital aural atresia requires careful consideration of technique and potential complications.
• Canaloplasty demonstrated a higher success rate in achieving audiological criteria compared to mastoidectomy with stapediopexy.
• Early identification and removal of hidden cholesteatomas are vital to prevent future complications.
