Nasal Soft Tissue Change Following Bimaxillary Orthognathic Surgery

Abstract

There was no significant correlation between the ABW widening and the vector of surgical maxillary movement. The effect and stability of the alar base cinch suture is difficult to determine and require further investigation.

Review of Nasal Changes With Maxillary Orthognathic Surgery

“…preoperatively and 12 months postoperatively for a cohort of patients undergoing bimaxillary surgery (involving maxillary advancement and cinch suture) found no significant correlation between the horizontal or vertical movement of A-point or ANS and the widening of the alar base (9). This was supported by another study assessing 3D laser scans (10).…”

“…Widening of the alar base occurs following almost all maxillary osteotomies, especially with impaction and/or advancement( 6 ) or segmental advancement and widening ( 7 ).It is the most consistently reported change in the literature ( 6 , 7 , 8 , 9 , 10 ). It has also been noted to occur with surgically assisted maxillary expansion ( 7 , 11 , 12 ).…”

“…The most likely explanation for this is the elevation of the periosteum off the anterior surface of the maxilla, together with the muscles and ligaments stabilizing the alar region ( 13 ). A study using CBCT images preoperatively and 12 months postoperatively for a cohort of patients undergoing bimaxillary surgery (involving maxillary advancement and cinch suture) found no significant correlation between the horizontal or vertical movement of A-point or ANS and the widening of the alar base ( 9 ). This was supported by another study assessing 3D laser scans ( 10 ).…”

Patients Satisfaction and Nasal Morphologic Change after Orthognathic Surgery

“…Bimaxillary orthognathic surgery leads to nasal morphological change 6 . The most significant changes include an increase in the alar base width and the nasal tip elevation 7,8 .…”

Cambio de imagen facial en base a rinoseptoplastía y cirugía ortognática: Resultados preliminares

“…Cuando existe una posición incorrecta en la estructura máxilo-mandibular debido a deformidades, es habitual observar otras anomalías del tercio medio facial, donde la nariz tiene un rol fundamental; una posición más inferior o excesivamente adelantada de la maxila implica el mismo cambio en la posición de espina nasal anterior (ENA), determinando una anomalía de posición de la base nasal 4 .…”
