Reconstruction of Congenital Alar Rim Defects (Tessier Number 1 Cleft) Using Laterally Based Alar Subunit Rotation Advancement Flap.

Abstract

Alar rim defects develop in most cases as a result of burns, trauma, or tumor excision. Congenital alar rim defects are rare, with an incidence of 1 in 20,000 to 40,000 live births. Tessier classification is the most commonly used classification system for craniofacial defects. Facial clefts involving the nose are categorized as types 0, 1, 2, and 3, whereas cranial clefts with nose lesions are categorized as types 11, 12, 13, and 14. The patterns of nasal clefts are extremely variable, ranging from a simple notch of alar margin to complex craniofacial cleft involving the lip, nose, eyelid, brow, forehead, and underlying bone. This study was conducted at Fayoum University Hospital on 8 male patients who present with congenital alar rim defects (Tessier number 1 cleft). Surgeries were performed under general anesthesia with orotracheal intubation. A full-thickness incision was created along the whole alar subunit, keeping the ala attached only laterally (laterally based alar full-thickness flap). The alar flap was advanced and rotated medially and inferiorly and sutured to the anatomical place in 2 layers, skin and mucosa. Follow-up was done at least 1.5 years postoperatively. The study was conducted on 8 male patients presenting with congenital alar rim defects (Tessier number 1 cleft). The mean age of patients was 14.2 years, and the cleft was unilateral in 4 patients (50%) and bilateral in 4 patients (50%). The patients were assessed both aesthetically and functionally and followed at 1.5 years postoperatively. The aesthetic outcome was assessed according to both patients' and author's evaluations of the scar appearance, alar symmetry, nostril symmetry, and general satisfaction. Laterally based alar subunit rotation advancement flap is a reliable option for reconstruction of congenital alar rim defects (Tessier number 1 cleft) with the advantages of being an easy single-stage procedure with good tissue matching and nostril symmetry and only limitation of extremely wide defects with deficient tissues between the ala and tip.
