“…1Y3,5,6,8,10,11,22,23,42 It appears reasonable to assume that combining transverse and midpalatal osteotomies provides the desired maxillary expansion of the anterior and intermediate portions of the maxilla. Because during pterygoid plate separation there is a risk of intraoperative bleeding, we agree to reserve pterygoid plate separation for situations in which the posterior portion of the maxilla is significantly affected 1,11,13,22,26,43 and in which there are posterior crossbites that must be addressed and corrected.…”

Surgically assisted rapid palatal expansion (SARPE) is the procedure of choice for treating transverse maxillary deficiency in adult patients. The use of computed tomography (CT) as a method of evaluating the efficiency of this procedure has not been yet reported. Consequently, few landmarks for use in evaluating maxillary expansion have been defined. The goals of the present study were to define parameters to assess skeletal changes after SARPE and to use CT to evaluate those parameters. From June of 2004 to May of 2005, 15 patients underwent SARPE (a modified Le Fort I maxillary osteotomy without pterygomaxillary separation, together with a sagittal palatal osteotomy) according to a defined protocol. To determine the pattern of transversal expansion, linear and angular measurements of the anterior, intermediate, and posterior portions of the maxilla were evaluated in axial and coronal views. The cross-sectional area of the maxilla was calculated to obtain general information about maxillary expansion. The reliability of the method was confirmed. Significant overall expansion was observed. However, different patterns of expansion were seen in the three regions analyzed. In the anterior and intermediate portions of the maxilla, the increase in maxillary width was greater than that observed in the posterior portion. The transverse expansion of the maxilla achieved through SARPE without pterygoid plate separation was less than uniform. The accurate evaluation of the postoperative changes was heavily dependent upon images acquired through CT.

“…However, limited benefits have been shown in mature teenage and adult patients since closure of the maxillary suture increases resistance to expansion, which produces negative dental and skeletal effects and increases the risks of relapse. [11][12][13] When maxillary retrusion is present in growing patients, early treatment with maxillary protraction appliances (Delaire-type facemasks) showed promising results whether or not they were used in conjunction with palatal expansion devices. This orthopedic therapy allows the maxilla to move forward and downward through the remodeling of the circummaxillary sutures while the mandible shows a posterior rotation, which corrects the soft tissue profile concavity.…”

Aim:The authors' propose to combine the reverse pull headgear with a Delaire type face mask and a maxillary corticotomy to treat a Class III non-growing patient with maxillary retrusion. The aim of this report is to present two cases in which this treatment strategy was successful.Background: Several studies suggest the majority of Class III dento-skeletal malocclusions have components of maxillary retrusion. Early treatment of these patients with maxillary protraction devices have shown promising results. Facemask therapy has some important limits. Most important is the optimal timing of treatment between the ages of six to ten years. Closure of the maxillary suture occurs as a child ages which results in an increase of maxillary resistance to protraction. Report:A proposed therapy carried out in orthodontic and surgical phases was used in the treatment of two young patients. They were both beyond the optimal age range for the application of the orthopedic device (a girl 15 years old and a boy 16 years old), however, they had not reached the necessary skeletal maturity for orthognathic surgery. Summary:The described technique has the advantage of being quick and easy to perform with a low surgical risk yielding satisfactory results after 15-20 days of therapy instead of the six to nine months associated with traditional procedures.

“…This technique has however been shown to have a limited effect on mature teenagers and adult patients. 36 This is explained by progressive midpalatal sutural closure that increases the resistance of the maxilla to expansion during the late teen years 18,29 .…”
