ABSTRACT
The discussion on how to correct the nasal base in cleft lip (CL) rhinoplasty focuses
on timing of the surgery, the type of approach, and the technique of repositioning
the ala. Little attention is paid to the nasal vestibule. We compared the results
of two different techniques. Forty-two patients were operated on via an endonasal
approach with total mobilization of the lateral crus and fixation after repositioning.
An external approach was used in 12 patients and the lateral crus freed as a medially
based chondrocutaneous flap. The defect in the lateral vestibule wall was covered
with an ear composite graft. The latter group showed more stable results concerning
symmetry and breathing. We conclude that in most cases of unilateral CL noses there
is not only a malposition and deformity of soft tissues and skin of the ala, but also
a deficiency in the surface of inner lining of the nasal vestibule that needs appropriate
repair. In general, the numerous procedures for repair of the nasal base in unilateral
CL patients can be attributed to three principles based on different philosophies
concerning the underlying pathology.

terms ``lower and upper lateral cartilages'' as we feel that these are not anatomically
correct.
