Summary

Three dimensional evaluation of nasolabial changes following classic versus modified alar cinch suture after Le Fort I osteotomy using cone beam computed tomography

Conditions

  • Le Fort; I

Interventions

PROCEDURE

Classic alar base suture technique

An index finger will be used to apply extraoral pressure on the alar base region, and a dentate forceps will grasp this tissue through the intraoral incision. A suture bite will be taken at this point through the tissue previously held by the forceps. The same procedure will be applied on the opposite side. After passing the suture on both sides, it will be tightened with attention to the alar base response. If the alar base suture will be judged to be adequate, the vestibular incision will then be closed in a routine fashion, with or without performing a V-Y lip closure

PROCEDURE

Modified alar base suture technique

The alar base will be marked with 3 landmarks: left alar base (point LAB), columella (point C), and right alar base (point RAB). A needle will be inserted through the skin at the nasofacial skin fold and exited through the fibroareolar tissue. A nonabsorbable suture without a needle will be inserted through the needle from the oral cavity to the outside. The needle will be retracted through point RAB without leaving the skin point, then returned to the oral cavity in a medial position. Finally the needle will be retracted from point RAB, leaving the suture through the soft tissue. The same procedure will be repeated on the other side. The 2 free ends of the sutures will be then tied together after passing through a hole made in the nasal spine.
