“…6 The treatment outcomes associated in the literature with applied RME are mainly discussed in terms of changes in dentofacial morphology, nasal resistance and nasal dimensions. [7][8][9][10][11][12][13][14] Still, there are some studies concerning changes in the pharyngeal airway and head posture before and after rapid maxillary treatment. [15][16][17][18][19][20][21][22] The aim of this study was to evaluate the effects of RME on the changes in head posture and airway dimension.…”

Introduction: Nasopharyngeal obstruction is an important etiologic factor in the development of an extreme vertical growth facial pattern, and insufficient transversal growth of the maxilla. The treatment outcomes associated with rapid maxillary expansion in the literature are mainly discussed in terms of changes in dentofacial morphology, without special reference to changes in the pharyngeal airway, the position of the mandible, hyoid bone and the tongue.

“…1,2 Transverse maxillary deficiencies may give rise to several clinical manifestations such as maxillary hypoplasia, asymmetrical facial growth, positional and functional mandibular deviations, altered dentofacial esthetics, adverse periodontal responses, unstable dental tipping, and other functional problems. 3 Posterior crossbite is one of the most prevalent malocclusions; it is reported to occur in 8% and 22% of patients and requires early intervention to coordinate the maxillary and mandibular arches.…”

Introduction The diversity of the proposed techniques in the treatment of maxillary transverse deficiency in adults reflects the conflicting opinions about the primary area of resistance to maxillary expansion in the craniofacial skeleton. In order to evaluate the efficiency of the surgical expansion in which no osteotomies of the pterygomaxillary junction were made, we have carried out a retrospective study with 14 patients with maxillary transverse deficiency, who were treated from 2003 to 2006. Material and methods In the study, models were made prior to and after surgery, and the intercanine and intermolar distances and the improvement of the interocclusal relationships were analyzed. Breathing function and the complications that occurred during and after the surgeries were also analyzed. Results All expansions were carried out according to pre-surgical planning so that expansion completely corrected the crossbite, resulting in the desired final occlusion for all patients. Intraoperative complications were limited to one Hyrax appliance deformation. Two patients had minor postoperative complications that included wound dehiscence and pain. Improvements in nasal breathing were observed in all patients that complained of breathing problems prior to the surgery. Conclusion The satisfactory results obtained turns the surgical protocol described in this study recommended for the treatment of maxillary transverse deficiency in adults. Importantly, we found that pterygomaxillary osteotomy is not essential for maxillary expansion. The morbidity of the procedure was low with fairly minor complications, and surgically assisted rapid maxillary expansion was shown to improve nasal breathing.
