Where is the alar groove?
The alar groove, which lies at the junction of the lower lateral crus (medially) and the alar lobule (laterally), is defined not as much by a muscular attachment between the perichondrium of the lower lateral cartilage and the vestibular mucosa as by a bulging in the fatty layer on one side of the groove (within the …
What is alar cartilage?
Anatomical terminology. The major alar cartilage (greater alar cartilage) (lower lateral cartilage) is a thin, flexible plate, situated immediately below the lateral nasal cartilage, and bent upon itself in such a manner as to form the medial wall and lateral wall of the nostril of its own side.
What is the dorsum nasi?
The dorsum nasi is the length of the nose. The apex is the tip of the nose. On either side of the apex, the nostrils are formed by the alae (singular = ala). An ala is a cartilaginous structure that forms the lateral side of each naris (plural = nares), or nostril opening.

Can nasal ala and tip defects be repaired following skin cancer resection?
Reconstruction of nasal ala and tip following skin cancer resection Nasolabial flaps showed excellent cosmetic results for the reconstruction of nasal ala defects, while primary closure and bilobed flaps yielded excellent cosmetic results for the reconstruction of nasal tip defects.
How is the alar crease reconstruction of a nasal flap performed?
For one-stage reconstruction, during inset of the flap, two nylon sutures can be placed from the deep side of the flap into the nasal vestibular skin permanently to recreate the alar crease.
What is the best technique for nasal ala reconstruction?
Flap or graft: The best of both in nasal ala reconstruction Augmenting a skin graft with a subcutaneous fat transposition flap is a simple technique that is quick to learn and straightforward to execute. Excellent outcomes were consistently obtained without the asymmetry and pin-cushioning often associated with local flaps at this site.
Which nasal flaps are best for nasal tip and Ala defects?
Nasolabial flaps showed excellent cosmetic results for the reconstruction of nasal ala defects, while primary closure and bilobed flaps yielded excellent cosmetic results for the reconstruction of nasal tip defects.
