Repair of Choanal AtresiaWilliam Lawson

Choanal atresia is generally unilateral and predominantly bony in nature. In infants, the life-threatening nature of the condition requires immediate correction, which is generally performed by transnasal perforation and curettage of the atretic area. Despite prolonged stenting, many cases subsequently require revision in later childhood, often by a transpalatal approach.

• Endoscopic transnasal approach
• Transpalatal approach

• Conventional and powered instrumentation may be used.
• This approach provides better visualization and tissue removal, with a high degree of success.
