Abstract
Alar lobule harmony plays an important role in the nasal base balance. Nasal alar deformity (NAD) can affect both nasal breathing and the aesthetic appearance of the nose. NAD can be congenital or acquired. The acquired causes include post rhinoplasty, traumatic, burn, tumour excisions, and neurogenic causes as stroke or facial nerve palsy. Congenital alar rim deformity occurs within craniofacial clefts.
A facial aesthetic analysis is essential in this context, in which the nasal anthropometric measurements should be assessed and, from them, a surgical plan should be created so that the desired results can be achieved.
The alar rim consists of overlying skin and underlying vestibular skin with lateral crus of the lower lateral cartilage in between for at least half of its length, from where it obliquely angled posterocephalic. The later almost part extend posteriorly toward the pyriform aperature where it is held by loose fibrous attachment, the cephalic edge usually overlaps the upper lateral cartilage to which it is attached by fibrous tissue. The cartilage is narrowest at the dome and gradually widens as it extends laterally to support the ala. The lateral crus most often slightly convex, though it varies in degree of convexity it may be convex, flat, or concave or any combination of these. The lateral wall reflects the support and proximity of the lateral crura to the alar rim. It is the cephalic sweep of the lateral cartilage away from the rim that creates the alar rim breakpoint and marks the junction between lobule and alar base.
Correction of alar rim deformity makes extensive demands of the plastic surgeon’s skill due to its three-dimensional anatomy and to provide symmetry and maintenance of nasal function.
The main aim of this study was to evaluate the different techniques for correction of nasal lobule deformity whether resulting from injuries or post rhinoplasty and find out an algorithm of management.
