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).

bimaxillary protrusion with first premolar extractions and total arch distalization with palatal anchorage plates," American Journal of Orthodontics and Dentofacial Orthopedics, vol.
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
Correlation analysis of the hyoid bone position in relationto the cranial base, mandible and cervical part of vertebra with particular reference to
bimaxillary relations/teleroentgenogram analysis.
