Popis: Le Fort I osteotomy causes nasolabial alterations that may be unattractive, such as expansion of the alae and alar bases and thinning of the upper lip. After maxillary impaction, there is a propensity for the tip to elevate, and in some circumstances, this may even become excessive. The nasolabial angle closes and similar alterations are observed with maxillary advancement. When Le Fort I impaction or maxilla advancement occurs, the alar base cinch suture is frequently utilised to reduce the unfavourable rise in nasal width. There are significant changes in the nasolabial morphology associated with Le Fort 1 osteotomy. Numerous changes occur after the surgical intervention in the maxilla namely- widening of the alar base of the nose, upturning of the nasal tip, flattening and thinning of the upper lip and down turning of the commissures. Widening of the alar bases of the nose appears to be the most common undesirable outcome. Some people may benefit aesthetically from nasal widening. For instance, the long face syndrome is frequently characterised by a narrow nose with a large dorsum. In these situations, superior maxillary relocation typically improves the look of the nose by enlarging the bases of the arches. However, excessive alar base broadening and superior retraction would cause the alar-facial groove to aesthetically deepen, giving the patient an older appearance, and may cause asymmetry in the alas. It is crucial for the surgeon to comprehend the preoperative aesthetic facial linkages and anticipate any potential impact the surgical operation may have on the nasolabial region before performing maxillary surgery. To control the width of the alar base after maxillary osteotomy clinicians have advocated the placement of cinch sutures, reduction of the anterior nasal spine and use of V-Y closure technique. There are inconstant opinions on the effect of the cinch suture.
