[Experimental and clinical studies on sternocleidomastoid myoperiosteal flap for laryngotracheal reconstruction].
In order to explore the value of sternocleidomastoid myoperiosteal flap for laryngotracheal reconstruction, eight dogs were included in the experimental study. After resecting the anterior body of the cricoid cartilage and tracheal tissue, the sternocleidomastoid myoperiosteal flap was used to close the defect immediately. All dogs were killed at two, four, six and eight months after operation. It was found that the sternocleidomastoid myoperiosteal flap had incorporated completely into the defect. Histologic studies by light and scanning electron microscopies showed complete epithelialization with no granuloma formation on surface of the flap and apparent metaplastic new bone formed in the periosteum which was crucial to the stability of the air way and long-term success of the procedure. Five patients who underwent subglottic and tracheal reconstruction with sternocleidomastoid myoperiosteal flap were successfully decannuated and had normal exercise tolerance. The results indicate that the sternocleidomastoid myoperiosteal flap is an ideal transplant for laryngotracheal reconstruction.
