Cricotracheostomy for Anatomically Challenging Severe Scoliosis: A Report of Two Adult Cases

Cricotracheostomy is a modified tracheostomy technique that involves partial resection of the anterior cricoid cartilage, which enables high-level airway access while minimizing the risk of subglottic stenosis. This report describes two adult cases of congenital scoliosis with complex skeletal deformities, including tracheal deviation and restricted neck extension, wherein conventional tracheostomy was challenging. In both cases, cricotracheostomy successfully provided stable airway access without complications such as granulation tissue formation, infection, or subglottic stenosis during follow-up. This report supports the utility of cricotracheostomy as the primary surgical approach in patients with severe skeletal deformities.
