Purpose: The aim of this study was to examine changes in the electromyographic activity, thickness, width, and hardness of the masseter muscle from before to after orthognathic surgery., Material and Methods: The study included 15 patients with Class III dentofacial deformities who were treated with combined orthodontic and orthognathic surgery. Fifteen individuals with normal occlusion and no signs or symptoms of temporomandibular joint dysfunction were used as controls. All records were obtained bilaterally in the study group before surgery (T1), at 3 months after surgery (T2), and in the control group (CG) while at rest and in maximum voluntary contraction (MVC)., Results: There was no difference in resting masseter muscle activity between T1, T2, and CG. Resting thickness and width of the masseter muscle did not differ significantly between T1 and T2. MVC masseter muscle activity and thickness increased significantly and width decreased significantly from T1 to T2 but did not reach CG values. Muscle hardness increased from T1 to T2., Conclusions: The authors' findings indicate that despite improved muscle activity and dimensions, postoperative 3 months is still early period for adaptation of the masseter muscles to the new occlusion and skeletal morphology.

Introduction: This study aimed to explore the effect of alveolar bone grafting on the clinical outcomes, health quality, and satisfaction in patients with cleft lip and palate., Materials and Methods: Questionnaire review study was done to patients who underwent secondary alveolar bone grafting retrospectively. This study included 28 patients who underwent secondary alveolar bone grafting by harvesting graft from the anterior iliac crest, excluding one, in Oral and Maxillofacial Department, Faculty of Dentistry, Ankara University, Turkey, during the period from January 2012 to March 2016. All patients were operated using the same technique and by the same surgical team. Patients were interviewed to fill Short-Form Health Survey (SF-12) and Postsurgical Patient Satisfaction Questionnaire (PSPSQ) 6 months postoperatively. The questionnaires were used to assess the relationship between health quality and patient satisfaction. Also, grafted sites were evaluated with respect to fistula, presence of cleft palate., Results: The sample consisted of 28 patients (19 females and 9 males), including 13 with bilateral clefts and 15 with unilateral clefts. The mean Physical Component Summary (PCS) and Mental Component Summary (MCS) of SF-12 scores were 54.5718 and 44.6436, respectively. The mean PSPSQ score was 36.7368. PCS scores were found to be significantly correlated with the PSPSQ scores (P ≤0.05). No correlation was found between MCS and PSPSQ scores (P >0.05). A precise and good planned surgery resulted in good satisfaction among patients with cleft lip and palate who underwent alveolar bone grafting. The patient satisfaction was correlated with the success of the operation.

Purpose: To study the use of blood culture bottles for culturing vitreous specimens in acute-onset postoperative infectious endophthalmitis cases., Methods: Forty-eight eyes of 48 patients with mean age of 66.4 +/- 14.7 years with postoperative endophthalmitis that occurred within 6 weeks after ocular surgery, presenting from June 2001 to January 2005, were retrospectively studied. Vitreous fluid specimens of these patients were cultured in blood culture bottles. The measured outcome is the yield of positive culture., Results: Vitreous specimens yielded positive in 34 of 48 (70.8%) eyes with blood culture bottles. The most common organism isolated was Staphylococcus epidermidis in 17.6% (6/34) of cases., Conclusion: The direct inoculation of vitreous specimens into the blood culture bottles is easy to perform, with a high yield positive rate (70.8%). It may be an alternative to conventional culture media for culturing vitreous specimen in infectious endophthalmitis especially in clinics or hospitals that are unable to have adequate microbiology laboratory facilities.
