Abstract
BACKGROUND: Several correlations between morphological and/or positional alterations of the jaws and respiratory functional impairments have been reported. NAO (Nasal airway obstruction) represents a big deal with no clearly defined "gold- standard" in measurement. Rhinomanometry was adopted by multiple Authors to evaluate whether patients with malocclusion developed respiratory functional changes after an orthodontic-surgical treatment. However there are contrasting findings in literature regarding the possibility of improving respiratory function by means of SARPE or bimaxillary repositioning of the bony bases.
METHODS: Ten patients ranging from 18 to 30 years of age scheduled for orthodontic-surgical treatment of maxillary constriction volunteered as participants for the study. Orthognatic surgery consisted in: a. surgically-assisted rapid palatal expansion in 4 patients; b. Le Fort I down fracture combined with a bilateral sagittal split osteotomy (BSSO) in 6 patients. All patients underwent a computerized rhinomanometric test before treatment (T0) and 40 days after surgery, at the time of the inter-maxillary splint removal (T1). Specifically, all 10 patients received AAR evaluations, while 6 patients received both AAR and APR evaluations.
RESULTS: Both AAR and APR tests showed a decrease in mean nasal resistance following the intervention. As regards the AAR, a difference of 0.19 Pascal/sec per cm3 was found. The difference found for APR 75 Pascal was 0.24 Pascal/sec per cm3, while for APR 150 Pascal is of 0.20 Pascal/sec per cm3.
CONCLUSIONS: This study helps to confirm respiratory benefits obtainable after mono and bi-maxillary orthognathic surgery.
