Anterior nostril atreplasty

Anterior nostril atresia generally only involves the skin of the anterior nares, the lock is relatively shallow, there are not many skin defects, and no skin grafting is required during surgery. Treatment of diseases: congenital stenosis and atresia Indication Stenosis or atresia of the bilateral or unilateral anterior nares. Preoperative preparation Prepare the plastic tube for expansion. Surgical procedure 1. The anterior nostril of the occlusion usually has a small venting hole (for example, there is no small venting hole, and the midpoint of the occlusion can be selected). With this small hole as the center, a radial surface layer skin incision is made to the circumference as needed. 2. Peel the skin and the underlying connective tissue to the size of the nostrils to be reached to form four small pieces of skin. 3. Repair the underlying connective tissue, expose the thinner skin of the vestibular surface, and then cut radially around the incision, the direction of the incision intersecting the incision of the superficial skin. 4. The four flaps cut from the outer layer are cross-stitched with the four flaps cut in the inner layer. 5. After suturing, put a silicone rubber or plastic tube in the nostril to prevent the scar from contracting. The plastic tube can be made into a shape suitable for indwelling in the nasal vestibule to make it easy to fix.
