Application of Auricular Cartilage-Skin Graft in the Reconstruction of Unilateral Cleft Lip Nasal Deformity

Abstract

Background: Autologous cartilage grafts are increasingly used in the treatment of cleft lip nasal deformity, but nasal alar retraction caused by lining defects often occurs after surgery. We designed a new graft to treat unilateral cleft lip nasal deformity while avoiding nasal alar retraction.

Methods: Nineteen patients in our hospital underwent unilateral cleft lip nasal deformity repair surgery with an auricular cartilage-skin graft. The effect of surgery was evaluated in four aspects: satisfaction with postoperative appearance, nasal aesthetic subunit indices, position of the nasal alar rim and three-dimensional spatial difference.

Results: Overall satisfaction with each index was above 90%. The nasal tip angle and nasolabial angle of patients were significantly smaller after surgery than before surgery (P < 0.01). The height of the nostril on the affected side and the length of the nasal columella were greater after surgery than before surgery (P < 0.01). The spatial differences in soft tissue between the unaffected side and the affected side after surgery were significantly smaller than before surgery (P < 0.01). According to the follow-up results of 1-2 years, there were no significant retraction of the nasal alar rim (P > 0.05) and no obvious auricular deformity. All patients had a noticeable improvement in their nasal appearance.

Conclusion: The auricular cartilage-skin graft, which can not only improve the appearance of the nose but also avoid nasal alar retraction, is an ideal graft to cure unilateral cleft lip nasal deformity.
