“…There continues to be debate in regard to the airways. Some authors found no significant changes in the sagittal dimensions of the oropharynx or the nasopharynx (Baccetti et al, ), whereas others even claim that the expected increase in pharyngeal volume decreases (Pamporakis et al, ). Other authors reported an increase in volume in the nasopharynx (Lee et al, ; Kaygisiz et al, ; Sayinsu et al, ), the upper airways (Oktay & Ulukaya, ), the oropharynx, and the nasopharynx (Auconi et al, ).…”

The facemask is a widely used device in the treatment of Class III malocclusion and is intended to anteriorly displace the superior maxilla or stimulate its growth in that direction. The main goal of this study was to evaluate the effects of treatment using orthopedic maxillary expansion with facemask therapy in patients with Class III malocclusion. Sixty‐four patients, with a mean age of 8.14 ± 1.18 years at the start of treatment and a mean age of 9.78 ± 1.19 years at the end, were treated using orthopedic maxillary expansion and associated facemask therapy. The patients were evaluated using lateral head teleradiography before and after treatment, and the differences were analyzed. In addition, binary logistic regression was used as a model for predicting successful treatment. When comparing the changes achieved by treatment, statistically significant favorable changes were found at the skeletal level. Furthermore, an improvement in the airways at all levels was detected. Orthopedic maxillary expansion associated with facemask therapy has proven effective in treating early skeletal Class III malocclusion.

“…A recent 3D CBCT study compared airway volumes of subjects treated with protraction face mask and untreated controls. 27 They reported no significant change in the oropharynx as a result of face mask treatment. Interestingly, the authors noted that the oropharyngeal volume in the face mask group was smaller than in untreated controls.…”

“…However, cephalometric studies have concluded that while maxillary protraction increased the nasopharyngeal airway, it did not significantly affect the oropharynx. 26,27 Mucedero et al 20 compared Class III patients treated with protraction face mask, protraction face mask with rapid palatal expansion, and untreated controls. While there were statistically significant skeletal improvements with the protraction groups compared with the untreated Class III controls, there was no difference in nasopharyngeal and oropharyngeal dimension between the groups.…”

Objectives: To compare airway volumes and minimum cross-section area changes of Class III patients treated with bone-anchored maxillary protraction (BAMP) versus untreated Class III controls. Materials and Methods: Twenty-eight consecutive skeletal Class III patients between the ages of 10 and 14 years (mean age, 11.9 years) were treated using Class III intermaxillary elastics and bilateral miniplates (two in the infra-zygomatic crests of the maxilla and two in the anterior mandible). The subjects had cone beam computed tomographs (CBCTs) taken before initial loading (T1) and 1 year out (T2). Twenty-eight untreated Class III patients (mean age, 12.4 years) had CBCTs taken and cephalograms generated. The airway volumes and minimum crosssectional area measurements were performed using Dolphin Imaging 11.7 3D software. The superior border of the airway was defined by a plane that passes through the posterior nasal spine and basion, while the inferior border included the base of the epiglottis to the lower border of C3. Results: From T1 to T2, airway volume from BAMP-treated subjects showed a statistically significant increase (1499.64 mm 2015;85:591-596.)

“…Pharyngeal size is very important for all patients and particularly for the patient with sleep apnea. The size of the nasopharynx may be of particular importance in determining whether the mode of breathing is predominantly nasal or oral.A few studies have investigated the relationship between extra oral maxillary protraction and pharyngeal size [17][18][19]. However, no research has ever been done to evaluate the relationship between pharyngeal airway space and tongue appliance.…”

Aim:The relationship between position of the maxillary structures caused by maxillary protraction therapy and airway dimensions has not been investigated as comprehensively as the skeletal changes. This study was conducted to evaluate the effects of treatment with a maxillary protraction appliance on upper airway dimensions. Material and Methods:Twenty Five patients including 13 females, 12 males with the mean age of 10.66 years (range, +0.7, -0.8 years) with skeletal Cl III malocclusion due to maxillary deficiency were selected in this study. All of the patients were treated by using a maxillary protraction (Tongue Appliance) as the only treatment appliance. Lateral cephalograms were taken before and after treatment. Data were analyzed statistically by means of paired T-test. Results:No significant increase in the width of upper and middle horizontal airway dimension was seen. Significant increases were observed in the length of vertical airway dimension (P<0.001). Conclusion:These results demonstrated that Tongue Appliance doesn't affect sagittal airway dimensions but it increases vertical dimensions in the short time.Therefore, the purpose of this study was to examine the effects of an intra-oral maxillary protraction appliance named tongue appliance on the dimensions of the upper airway in patients with Cl III malocclusion and maxillary deficiency. Materials and MethodsThe study was done according to the ethical principles of the Declaration of Helsinki.In this study 25 patients (13 females, 12 males) with mean age of 10.6 (SD 0.7) years who were treated with tongue appliance were selected. All samples had following inclusion criteria.Presence of a skeletal Cl III malocclusion due to maxillary deficiency with SNA≤78. SNB ≤80. ANB ≤0 Edge to edge incisor relationship or anterior crossbite, flat or concave facial profile.The patients were treated with tongue appliance alone.4-No other congenital anomalies, endocrine, nasopharyngeal disorders, tonsillitis, adenitis, previous orthopedic, orthodontic treatment, and rhinoplasty were present.Tongue appliance [10] used for the treatment of the samples was constructed by Adams clasps for first upper molars and c clasps in the anterior teeth in order to increase the retention. Three to five separate spurs incorporated in the palatal between canine to canine areas. These spurs were as long as to cage the tongue and they were adjusted in clinic to avoid traumatizing the floor of the mouth. This appliance was used for approximately 22 hours a day. The average treatment IntroductionThe skeletal and dentoalveolar effects of orthopedic appliances in patients with Class III (Cl III) malocclusions and maxillary deficiency have been well documented in literature. Numerous appliance designs such as endosseous implants [1], ankylozed teeth [2], surgically assisted orthopedic protraction [3], distraction osteogenesis [4,5], Hybrid Hyrax appliance [6], reverse chin cup [7,8], face mask [9], tongue appliance [10][11][12], and tongue plate [13] have been used for treatment ...

Three-dimensional alterations in pharyngeal airway and maxillary sinus volumes in Class III maxillary deficiency subjects undergoing orthopedic facemask treatment

Abstract: RME/FM treatment did not affect at all the volume of maxillary sinuses and actually inhibited the normal expected increase of the volume of the pharynx when compared with a control group comprising normal individuals.
