Superiorly based tracheostomal flap to counteract tracheal stenosis: experimental study.
A superiorly based tracheal flap raised from the anterior tracheal wall was rotated anteriorly and superiorly to be sutured to the subcutaneous tissues. A series of 16 tracheostomies were performed on mongrel dogs. The stenosing effects of conventionally performed operations were compared to those of the new method. Autopsy sections of the post-tracheostomy sites demonstrated a significant loss of anteroposterior diameter averaging 16.5% as compared to the original unoperated-on luminae. No signs of tracheal stenosis were found whenever the proposed new technique was employed. This technique seems applicable to patients in whom assisted ventilation is contemplated.
