Nasal and pharyngeal airway changes following three different rapid palatal expansion protocols in nongrowing subjects: Effects of miniscrew-assisted rapid palatal expansion and surgically-assisted rapid palatal expansion with or without pterygomaxillary disjunction.
Objective: Comparing nasal cavity and pharyngeal airway volumes and minimum cross-sectional areas in nongrowing patients who underwent miniscrew-assisted rapid palatal expansion (MARPE) or surgically assisted rapid maxillary expansion (SARME) with and without pterygomaxillary disjunction (PD).
Methods: Pretreatment and post-expansion cone beam computed tomography scans of 30 patients (mean age: 18.6 years), diagnosed with maxillary transverse deficiency, were grouped into three (n = 10 each) according to expansion protocol: 1) MARPE; 2) SARME without PD [SARME-PD(-)]; 3) SARME with PD [SARME-PD(+)]. In NemoStudio software, eleven linear measurements were used to evaluate nasal and maxillary skeletal parameters. Eight airway measurements were used to evaluate the volume and minimum cross-section of the nasal cavity, nasopharynx, retropalatal region, and retroglossal region. Intragroup and intergroup changes were evaluated for statistical significance at P < 0.05.
Results: Nasal lateral, nasal floor, external maxillary, palatal, and maxillary intermolar widths significantly increased in all groups. In MARPE, nasal cavity and nasopharynx volumes and minimum cross-sectional area increased significantly. Nasopharyngeal volume increased significantly in SARME-PD(-), whereas nasal cavity volume and minimum cross-sectional area decreased significantly in SARME-PD(+). MARPE group showed greater expansion in nasal lateral width than SARME-PD(-) and SARME-PD(+) groups. Mean changes in nasal cavity volume, minimum cross-sectional area, and nasopharyngeal volume were significantly greater in MARPE than in SARME-PD(+).
Conclusions: MARPE group showed greater increases in linear and volumetric measurements. However, differences were statistically insignificant compared to SARME-PD(-). Retropalatal and retroglossal parameters were unaffected in all groups. PD did not provide substantial advantage.
期刊介绍：
The Korean Journal of Orthodontics (KJO) is an international, open access, peer reviewed journal published in January, March, May, July, September, and November each year. It was first launched in 1970 and, as the official scientific publication of Korean Association of Orthodontists, KJO aims to publish high quality clinical and scientific original research papers in all areas related to orthodontics and dentofacial orthopedics. Specifically, its interest focuses on evidence-based investigations of contemporary diagnostic procedures and treatment techniques, expanding to significant clinical reports of diverse treatment approaches.
The scope of KJO covers all areas of orthodontics and dentofacial orthopedics including successful diagnostic procedures and treatment planning, growth and development of the face and its clinical implications, appliance designs, biomechanics, TMJ disorders and adult treatment. Specifically, its latest interest focuses on skeletal anchorage devices, orthodontic appliance and biomaterials, 3 dimensional imaging techniques utilized for dentofacial diagnosis and treatment planning, and orthognathic surgery to correct skeletal disharmony in association of orthodontic treatment.
