PAOO is contraindicated in cases where bimaxillary
protrusion with a gummy smile, which is benefited by segmental osteotomy.
According to these factors, bimaxillary
orthognathic surgeries were planned for both patients performed in an inverted sequence (mandible first).
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).

Brain MR surgery, bimaxillary
surgery, lateral skull based and temporal bone surgery are the main areas in which anatomical registration is used effectively.
Correction of symptomatic chronic nasal airway obstruction in conjunction with bimaxillary
orthognathic surgery: Does it complicate recovery and is it effective?
The effect of extraction versus non-extraction treatment on oropharyngeal airway volume with the aid of CBCT showed no significant differences in the oropharyngeal airway volume.36 It was found that extraction of the first premolars for the treatment of bimaxillary
protrusion did not affect upper airway dimensions despite the significant reduction in tongue length and arch dimensions.37
