Abstract
Background
Identifying the cause of alar retraction is essential for proper correction of this deformity. In secondary surgery, aimed primarily at cephalic orientation and medialization of the lateral crus, corrections involving spreading and lateralization of the lateral crus can achieve a more horizontal orientation. In their clinic, the authors have practiced the use of an alar spreader graft to support the spread of the lateral crus. For the lateral crus to move freely without any resistance, it is critical to release the nasal hinge and pyriform ligament. A frontal view of the alar notching and the direction of the lateral crus are highly important factors needed to determine the cause of alar retraction. This report describes a new classification system for alar retractions viewed from the front to aid in determining the cause of the retraction and the surgical management.
Methods
From March 2008 to July 2010, 31 alar retractions were corrected using alar spreader grafts for patients showing clear alar retractions in frontal views.
Results
Satisfactory results without severe complications were obtained in 30 cases, with undercorrection in only 1 case. The alar cartilage was completely released to facilitate lateralization and caudal mobilization. An alar spreader graft then was used to support the lateral crus until a biologic scar cast was formed.
Conclusion
The use of alar spreader grafts to correct alar retractions provided consistently good results. The attempt also was made to enhance the treatment strategy based on this classification system derived from frontal views of alar retraction.
