Review of the literature revealed congenital deficiencies of the alar cartilages are very rare.
In the first case, the use of the lower lateral turnover flap provided immediate satisfying esthetic results by diminishing the concave aspect of the right alar cartilage. Furthermore, right external nasal valve collapse was improved with increased right nasal airflow (Figure 1E-H).
However, as early as 3 months postoperatively, a change in the esthetic appearance of the nose was noticed consisting of recurrence of alar cartilage collapse as well as a depression at the level of the pyriform aperture.
The use of alar cartilage grafts in functional rhinoplasty surgery in order to correct valve insufficiencies is well-established and provides long-term stable and predictable results.
Nen uses transcartilaginous sutures to recreate the complex convexities of the alar cartilages [2].
A marked reduction in the alveolar defect and improved columella and nasal alar cartilage positioning was achieved [Figure 8,9,10,11]
The objectives include lip segments that are almost in contact at rest, symmetrical lower lateral alar cartilages, and adequate nasal mucosal lining, which permits postsurgical retention of the projected nasal tip.
The proper function of the nasal valve is dependent on the integrity of the upper lateral cartilages, the alar cartilages, the mucosal surface of the nasal valve, the nasal septum, and the intrinsic muscles of the nose.
