Evaluation of life quality of patients submitted to orthognathic surgery

Abstract: OBJECTIVE: To compare changes related to self-esteem and appearance satisfaction between pre and postsurgical phases in patients undergoing orthognathic surgery and to assess the quality of life and psychosocial changes of these patients six months after surgery. METHODS: A longitudinal observational qualitative study was performed. The sample comprised 15 patients with dentofacial deformities who underwent orthognathic surgery. One questionnaire and two forms were answered during pre and postoperative phases. RESULTS: The results showed that 13.3% of patients demonstrated self-esteem improvement, especially in relation to appearance satisfaction. Improvements were also noted in social, occupational and family relationships. With regard to the assessment of quality of life, according to the World Health Organization questionnaire, the lowest improvement averages corresponded to environmental control. CONCLUSION: Orthognathic surgery brings along many emotional changes that should be considered before and after surgery, since the patients' psychological state may be favorable and/or unfavorable during recovery, influencing their quality of life, self-esteem and appearance satisfaction.

Effects of walking and strength training on resting and exercise cardiovascular responses in patients with intermittent claudication

Abstract: Background: Exercise training is recommended as the first-line therapy for intermittent claudication patients However, the effects of exercise therapy on cardiovascular function of these patients have been poorly studied The aim of this study is to compare the effects of walking and strength training on cardiovascular responses assessed at rest and during exercise in patients with intermittent claudication Patients and methods: Thirty-four patients with stable symptoms of intermittent claudication were randomized into two groups: strength training (ST) consisting of eight exercises, three sets of 10 repetitions, intensity of 11 - 13 on 15-grade Borg scale, 2-min interval between sets; and walking training (WT) consisting of walking on a treadmill, 15 bouts of 2-min, intensity of 11 - 13 on 15-grade Borg scale, with a 2-min interval between bouts Before and after 12 weeks, blood pressure, heart rate and rate pressure product were measured at rest and during a progressive treadmill test until maximal cl

Treatment of chronic mandibular dislocations by eminectomy: follow-up of 10 cases and literature review.

Abstract: Introduction: Temporomandibular joint (TMJ) dislocation is defined as an excessive forward movement of the condyle beyond the articular eminence, with complete separation of the articular surfaces and fixation in that position. Objectives: To report ten cases treated by eminectomy for chronic mandibular dislocations, to evaluate the results of these surgeries and make a critical review of the literature. Methods: The sample was obtained from the records of the Department of Oral and Maxillofacial Surgery, University of Pernambuco and comprises cases submitted to chronic mandibular dislocation treatment by eminectomy between 2002 and 2007. Pre- and postoperative assessment included a thorough history and physical examination to determine the maximal mouth opening, presence of pain and sounds, frequency of luxations, recurrence rate and presence of facial nerve paralysis. Results: The mean maximal mouth opening in the preoperative period was 48.4 ± 8.5 mm and in the postoperative period it was 41.3 ± 5.0 mm. No facial nerve paralysis or recurrence was observed. Conclusion: The treatment of chronic mandibular dislocations by eminectomy was shown to be efficient in rela tionship to the postoperative maximal mouth opening, recurrence and articular function.

Embolization of pseudoaneurysm of the internal maxillary artery after orthognathic surgery.

Abstract: In orthognathic surgery, Le Fort I osteotomy is one of the most often used methods for the correction of dental-facial deformities and is considered technically safe. However, this procedure may lead to diverse complications, including uncommon vascular complications. A clinical case is described of late development of pseudoaneurysm in one of the branches of the maxillary artery in a 20-year-old patient who had undergone Le Fort I osteotomy, bilateral sagittal osteotomy of mandibular branch, and mentoplasty and subsequently treated with embolization. The main forms of treating vascular injuries are reviewed, and embolization is demonstrated to be a technically safe procedure with few complications.

Growing Self-Organizing Maps for Surface Reconstruction from Unstructured Point Clouds

Abstract: This work introduces a new method for surface reconstruction based on Growing Self-organizing Maps, which learn 3D coordinates of each vertex in a mesh as well as they learn the topology of the input data set. Each map grows incrementally producing meshes of different resolutions, according to the application needs. Another highlight of the presented algorithm refers to the reconstruction time, which is independent from the size of the input data. Experimental results show that the proposed method can produce models that approximate the shape of an object, including its concave regions and holes, if any.
