A modified alar cinch suture technique. Article (PDF Available) in European Journal of Plastic Surgery 32(6) · December with. Next, small amounts of the solution are injected beneath the alar bases and the nasolabial To control the width of the alar base, an alar cinch suture is used. Secondary changes of the nasolabial region after the Le Fort I osteotomy procedure are well known and include widening of the alar base of the nose, upturning.

An Alternative Alar Cinch Suture

The effect is checked externally. A dissection extending onto the anterior zygomatic arch necessitates sharp transsection of the adjoining masseter muscle attachments. In edentulous patients make sure to use a crest of the ridge incision rather than a sutrue incision. In our study we observed that for every unit increase in the intrusion there is 0.

Thirty-two patients with skeletal class III facial deformity who had orthognathic operations by the same surgeon were recruited in this study. Open in a separate window. The incision is carried down through the mucosa, submucosa, underlying facial muscles and periosteum …. Group comparison using paired sample t test was found to be significant. The two free ends of the sutures are passed through a hole made in the nasal spine making a knot.

The sutures are cut short, the forcep is released, and the knot can dig into the tissue channel made by the needle. The post-operative results in group 2 compared to pre-op, frontal and sub-nasal view, is depicted in Figs. Nasal profile changes after maxillary and advancement surgery. Our study confers these findings to some extent.


Suyure with Ethical Standards Conflict of interest None. Their study concluded that a mean increase in the width cinchh the base of the nose of 3. Then the medial and lateral bony buttresses are addressed: What is more important is the degree of subperiosteal dissection and the amount of soft tissue elevated, that in most surgical techniques involves the total maxilla.

Nasal widening, which is almost always observed after maxillary osteotomies, is only partially dependent on the amount of skeletal movement. Though the overall morbidity is low, potential complications can suturw from violating some anatomic structures:. Open in a separate window.

A line of a local anesthetic mixed with epinephrine 1: Prior to closing the mucosal incision of the maxillary vestibule, two strategies to compensate for contraction of the stripped nasolabial muscles are possible: In the illustration, one suture on each side of the V-Y closure is shown.

A prospective study on the effect of modified alar cinch sutures and VY closure versus simple closing sutures on nasolabial changes after Le Fort I intrusion and advancement osteotomies. However, the alar flare, resulting as a consequence of superior repositioning of the maxilla, mars the objective of correcting VME and gummy smile.

All the patients had bimaxillary operations, with or without genioplasty. Le Fort 1 intrusion osteotomies are known to cause adverse effects on the oro-facial soft tissues such as broadening of the alar base, loss of vermillion show of the upper lip and down sloping of the commissure [ 1 ].


Changes to the nose clearly occur after Le Fort 1 osteotomy superior repositioning.

Use of the alar base cinch suture in Le Fort I osteotomy: is it effective?

As soon as the correct plane is reached, the dissection is continued bluntly. We think that the procedure performed postoperatively creates a lot of discomfort for the patients; asymmetry due to the knot performed on a side of the nose and not in the midline may result. The free ends of the sutures are tied into a firm knot against the forcep that hold them together.

Beginning posteriorly, sutures are placed through mucosa, submucosa, aar, and periosteum in a staggered fashion bringing the upper vestibular mucosa in an anterior position along a rotational arch. Le Fort I osteotomy alters the proportion of the alar base and widens it, the superior or anterior maxilla movement has the most effect.

There was a statistically significant increase in post operative interalar width and inter-nostril width with maxillary movement. The nasal base changes were evaluated by the surgeon and the whole equipe.
