Reconstruction of the subglottic larynx with a myoperiosteal flap: clinical and experimental study.
The literature describes numerous techniques for reconstruction of the subglottic larynx. The use of rigid bone grafts or flaps has been associated with problems because the rigid bone cannot conform to the defect and form an airtight seal. We have performed subglottic reconstruction using the sternocleidomastoid myoperiosteal flap with very optimistic results on long-term follow up. The sternocleidomastoid myoperiosteal flap is a relatively simple procedure that can be used for a large variety of defects. The pliable periosteal flap used for closing the defect can be molded over a stent to form an airtight seal. We have demonstrated bone formation in the periosteum which is crucial to the stability of the airway and long-term success of the procedure. The sternocleidomastoid myoperiosteal flap yields a pliable, durable tissue capable of airtight closure and a tension-free suture line. This technique will make the closure of subglottic defects a much more practical task.
