Structural Approach to Secondary Repair of the Unilateral Cleft Lip Nasal Deformity.

Abstract

Management of the unilateral cleft lip nasal deformity is complex because of the underlying significant asymmetry of the lower lateral cartilages and soft tissues of the nasal base. Suturing and grafting techniques may leave the patient with residual asymmetries of the nasal tip and nostrils. Some of this residual asymmetry may be attributable in part to the anchoring effect of the vestibular skin attachments to the lower lateral cartilages. This article discusses the use of lateral crural release, repositioning, and support with lateral crural strut grafts to manage the nasal tip. The technique involves freeing the vestibular skin from the undersurface of the lateral crura and domes and placement of lateral crural strut grafts with or without amputation of the ipsilateral dome and lateral crura to allow precise resuturing to the caudal septal extension graft. This technique is coupled with the use of a caudal septal extension graft to stabilize the nasal base and provide a strong foundation for the repair. Treatment of the nasal base may require skeletal augmentation to aid in creating symmetry of the alar insertions. Costal cartilage is needed in most cases to provide adequate structural support. Nuances in technique are discussed to help maximize outcomes.
