Changes in acoustic airway profiles and nasal airway resistance after Le Fort I osteotomy and functional rhinosurgery: A prospective study

Computational Fluid Dynamic Study of Nasal Respiratory Function Before and After Bimaxillary Orthognathic Surgery With Bone Trimming at the Inferior Edge of the Pyriform Aperture

“…Many studies of the influence of maxillary superior repositioning using rhinomanometry and acoustic rhinometry show that nasal cavity resistance was reduced after surgery [7][8][9][10][11][12] . Similarly, our study showed that the pressure effort in many cases was reduced after surgery as described in Figure 10.…”

“…In previous studies using rhinomanometry and acoustic rhinometry, only the anterior nasal cavity including the cross-sectional area of the isthmus nasi and nasal valve was mentioned as a factor of decrease in nasal cavity resistance. [7][8][9][10][11][12] In addition to the anterior nasal M A N U S C R I P T…”

“…In some cases, functional rhinosurgery, such as resection of the inferior concha, correction of the septum, and contouring of the pyriform aperture, is performed simultaneously with orthognathic surgery. 7 However, the efficacy of these measures has not been investigated as yet.…”

Outcome Assessment of 603 Cases of Concomitant Inferior Turbinectomy and Le Fort I Osteotomy

“…Haarmann et al (2009) investigated the changes in nasal airways after Le Fort I osteotomies with concomitant nasal septoplasty and inferior turbinectomies using anterior rhinomanometry and acoustic rhinometry. Th e results of their analysis supported the improvement of the functional airway after surgery (38).…”

Le Fort I Osteotomy for Maxillary Repositioning and Distraction Techniques

“…Even if nasal breathing actually increase after maxillary advancement and impaction, in cases where a considerable amount of superior repositioning is planned, much attention must be paid in septum repositioning without deviations or bulking by proper remodeling or reductions of the osteo-cartilaginous portions, septal crest of the maxilla and lower turbinate (Haarmann et al, 2009;Posnick et al, 2007).…”
