Alterations in nasal respiration and nasal airway size following superior repositioning of the maxilla

Study of Anatomical Changes of the Inferior Nasal Passage After Le Fort I Osteotomy With Superior Repositioning

“…The potential effects of nasal cavity constriction include sinusitis, respiratory distress, and nasal obstruction. In addition to reports on respiratory disorders associated with maxillary-mandibular movement, 2–5 there are some reports concerning the condition of the nasal passage and nasal obstruction after Le Fort I osteotomy 6–17 . We reported that the contact rate between the inferior turbinate and the nasal cavity floor was 67.7% when the elevation exceeded 4.0 mm with maxillary movement 18 .…”

Effects of maxillary distraction osteogenesis on the upper‐airway size and nasal resistance in subjects with cleft lip and palate

“…In our study, we found that the decrease in nasal resistance in subjects with CLP who underwent maxillary DOG significantly correlated with the increase in the upper‐airway CSA. This suggests that there is a critical relationship between the gradual change in upper‐airway structure and function, as was noted in the acute change that followed orthognathic repositioning of the maxilla (19,20). We found that the increase in the upper‐airway dimension and the reduction in nasal resistance were still significant at 1 year after DOG.…”

Maxillary sinus recovery after LeFort I osteotomy: a prospective clinical and radiographic evaluation

“…Pereira et al [16] in his study showed 4.76% as the incidence of maxillary sinusitis after a Lefort I osteotomy and Moses et al [17] reported 7 cases of maxillary sinusitis as a postoperative complication after LeFort I osteotomies which were treated by endoscopic surgery, and he also reported that the anatomic changes in the sinus drainage area occurred mainly in cases of maxillary intrusion and severe asymmetries. At the time of orthognathic procedures, the surgeon has an opportunity to further contribute to a patient's quality of life by simultaneously addressing long standing breathing difficulties and pathologies associated with maxillary sinus that may coexist with the jaw deformity [18,19]. Even if the patient does not complain about these problems or is asymptomatic, pathologies related to maxillary sinus as well as any anatomical deformities that may lead to rhinosinusitis must be considered for correction during LeFort I osteotomy, as these problems might get aggravated or the patient may even become symptomatic after the surgery [20,21].…”
