“…Several studies have reported an increase of the nasal cavity volume and poor effect on oropharyngeal volume after SARME. 3,12 Nevertheless, patients tend to be reluctant to undergo surgical procedures due to trauma. Recently, mini-implant assisted rapid maxillary expansion (MARME) for mature patients has been demonstrated to provide similar skeletal expansion to SARME, reducing surgical injury and adverse dentoalveolar side effects.…”

Objectives To evaluate changes in dimensions and volume of upper airway before and after mini-implant assisted rapid maxillary expansion (MARME) and observe correlations between changes of upper airway and vertical skeletal pattern in young adults. Materials and Methods In this retrospective study, 22 patients (mean age, 22.6 ± 4.5 years; 4 male 18 female) with transverse discrepancy underwent MARME. Cone beam computed tomography was taken before and 3 months after expansion. Vertical and horizontal dimensions and volume of the nasal cavity, nasopharyngeal, retropalatal, retroglossal and hypopharyngeal airway were compared before and after MARME. Correlations between changed volume and dimensions were explored, as well as the vertical skeletal pattern. Results Nasal osseous width, maxillary width, volume of the nasal cavity and nasopharynx increased significantly (P < .05). Enlarged nasopharyngeal volume correlated with increased nasal width at the PNS plane (P < .05). There were no correlations between expanded volume and maxillary width. No measurements except nasal cavity volume had a correlation with Sum angle. Increased maxillary width correlated negatively with hard palate thickness (P < .05). Conclusions (1) MARME caused an increase in volume of the nasal cavity and nasopharynx, with expansion of nasal osseous width and maxillary width. (2) Enlarged nasal width at the PNS plane contributed to the increase in nasopharynx volume. Enlarged maxillary width showed no direct relation with increased volume. (3) In this study, it was unclear about the association between changes of the upper airway and vertical skeletal pattern because of complex structures. (4) Palate thickness affected skeletal expansion of the maxilla in MARME.

A ampla variabilidade dos resultados pode ser associada a grande variedade de técnicas e protocolos utilizados, bem como a escassez de estudos randomizados, com método e protocolos de avaliação padronizados (BUCK et al, 2016).…”

“…25 Iwasaki et al observed that RME not only reduced the nasal obstruction, but also raised the tongue and enlarged the pharyngeal airway volume. 26 Buck et al presented a systematic review on the effects of surgically-assisted rapid maxillary expansion (SARME) on the upper air-way volume and concluded that the effects of SARME on the respiratory function still needed to be evaluated, 27 and that was the aim of the present study.…”

Volumetric upper airway changes following a new technique for Surgically-Assisted Maxillary Expansion (SAME)

Background. Skeletal maxillary constriction (SMC) is one of the common skeletal discrepancies which are associated with alterations in the respiratory function. Today, many surgical techniques are used to expand the maxilla in adult patients with no consensus about the optimal technique. Objectives. The present study aimed to investigate the changes of the upper airway volume resulting from the use of a new, minimally invasive surgically-assisted maxillary expansion (SAME) technique, and compare the results with the conventional SAME technique. Material and methods. A prospective study was conducted between September 2015 and July 2018. A total of 28 adult patients (11 males, 17 females; mean age: 19.1 ±2.7 years) with SMC underwent SAME. The sample was divided according to the applied surgical technique into 2 groups: the conventional osteotomy SAME (CO-SAME) group consisted of 13 patients (18.7 ±2.2 years) and the selective osteotomy SAME (SO-SAME) group consisted of 15 patients (19.4 ±3.2 years). Cone beam computed tomography (CBCT) scans were initially obtained preoperatively (T1) and 3 months post expansion (T2). The upper airway was divided into 2 segments: retropalatal and retroglossal. The volume of each segment and the total airway volume (TAV) were assessed using the OnDemand3D ® software. Results. The total upper airway volume showed a significant increase after both CO-SAME and SO-SAME (1.29 ±0.26 cc and 1.21 ±0.19 cc, respectively), with significant increases in retropalatal and retroglossal airway volumes (RPAV and RGAV) after both CO-SAME and SO-SAME (RPAV-0.73 ±0.10 cc and 0.83 ±0.10 cc, and RGAV-0.56 ±0.23 cc and 0.38 ±0.23 cc, respectively). No significant differences were observed in the maxillary width (MW), TAV or RGAV between the 2 SAME techniques, whereas the increase in RPAV in the SO-SAME group was significantly greater than that of the CO-SAME group. Conclusions. The new, minimally invasive SAME technique was an effective procedure to increase MW and the upper airway volume.
