Introduction Orthognathic surgery involves making several osteotomies that lead to varying degrees of post-operative swelling. The use of KT may be beneficial for postoperative treatment after head and neck surgery, accelerating drainage of tissue reaction or haemorrhages. The goal of this study was to find out if the application of KT prevents or improves swelling, pain and trismus after orthognathic surgery, improving patients' postoperative quality of life. Materials and Methods In this double-blinded, randomized, control trial, 24 patients in whom bimaxillary orthognathic surgery was indicated, were included. Before surgery each patient alternatively was randomly included in the study group (treated with K-Taping Ò and corticosteroid) or in the control group (treated with corticosteroid). In the present study a MakerBot Ò Digitizer 3D TM was used to assess accurate volume measurements. All swelling measurements were expressed as total 3-D area of the landmarks (cm 2 ) in T0 pre-operative, T1 fourth day after surgery. Results The differences T0-T1 are highly significant (p \ 0.01) between group 1 or study group (treated with K-taping Ò ) and group 2 (control group). Discussion The use of KT appears promising, because it is simple to carry out, less traumatic, economical, can be performed everywhere in the world, free from side effects on the body. Even when swelling persists, KT gives patients the impression of a minor swelling detracting them from their pain and morbidity. Further studies have to be performed to find out if KT can reduce or replace the need for additional medications such as the use of steroids.

From this study, there is no evidence to support the advice for routine removal of titanium miniplates from the maxillofacial skeleton, although when using plates in the mandibular angle region, it would be necessary to inform the patient about the very high probability of a second operation necessary for the plates' removal.

Introduction Orthognathic surgery involves making several osteotomies. Any osteotomies leads to varying degrees of post-operative swelling. The aim of this study was to evaluate the effectiveness of anti-edema drugs for the control of edema, using Digitizer 3D TM for measuring softtissue thickness, in patients who underwent bimaxillaryorthognathic surgery. Materials and Methods In this double-blinded, randomized, control trial, 24 patients (study group: 12 patients, control group: 12 patients) in whom bimaxillary orthognathic surgery was indicated, were included in this study. All swelling measurements were expressed as total 3-D area of the landmarks (cm 2 ) in T0 pre-operative, T1 first day after surgery, T2 fourth day after surgery, T3 4 months after surgery. For each patient we compared, by adding left and right area, the increase of swelling between T1-T0, T2-T0 and T1-T3. Results The differences T0-T1 are highly significant (p \ 0.01) between group 1 or study group (treated with Venoplant Ò ) and group 2 (control group); the differences T0-T2 are significant (p \ 0.05) between group 1 (treated with Venoplant Ò ) and group 2 (control group). The differences T1-T3 are significant (p \ 0.05) between group 1 (treated with Venoplant Ò ) and group 2 (control group). Discussion The present study suggests that Venoplant Ò significantly decreases postoperative edema in orthognathic surgery, thus precluding long-term corticosteroid use.

Introduction Dentofacial deformity refers to deviations from normal facial proportions and dental relationships that are severe enough to be handicapping. These anomalies involve many aspects of patient's life and are sometimes also associated with a reduction of pharyngeal air space. Through orthognathic surgery it is possible to treat dentofacial deformities: this kind of surgery has several effects on skeletal structures and it has changes, as it is demonstrated by many studies, also on the upper airways. The orthognathic surgeries commonly used to correct this deformity are the mandibular setback and the maxillary advancement procedures. This study aims to evaluate the effects of maxillary and mandibular surgery on pharyngeal airway dimensions in skeletal class III malocclusions. Materials and methods This study considers 76 patients, treated between 2007 and 2013 by maxillary advancement (11 patients), maxillary advancement and mandibular setback (39 patients), maxillary advancement, mandibular setback and genioplasty reduction (26 patients). Cranial latero-lateral radiography was used to compare oropharyngeal airway morphologies before and 1 year after surgery. Conclusion The surgeon should consider bimaxillary surgery rather than mandibular setback surgery to correct a class III deformity to prevent the development of obstructive sleep apnea syndrome; in fact, bimaxillary surgery might have less effect on reduction of the pharyngeal airway than mandibular setback surgery only.
