Abstract
OBJECTIVE The purpose of this study is to assess the impact of Sagittal Split Ramus Osteotomy (SSRO) on the alignment of the condyle and orientation of the Ramal segment following surgery in patients operated for the correction of mandibular asymmetry. METHODS A total of 27 patients who underwent SSRO were enrolled in this study, and study groups were defined as asymmetric (study group) and symmetric (control group) using linear measurements from the dental midline based on a three-dimensional coordinate system. Differences on preoperative and postoperative values of anterior (AJS), posterior (PJS) and superior joint spaces (SJS), condylar axial angle (CAA), Sagittal Ramal Angle (SRA), and Coronal Ramal Angles (CRA) of study and control groups were measured and compared. The data was analyzed using the "Wilcoxon signed-ranks test" to identify differences between groups. RESULTS Differences between preoperative and postoperative values of CRA and SRA of the contralateral group showed statistically significant results with p-values of 0.007 and 0.005, respectively. A statistically significant change in CAA angle was found in the control and deviation groups (p = 0.018 and p = 0.010, respectively). CONCLUSIONS SSRO has inevitable effects on the condylar and ramal orientation. Individuals with asymmetry require particular attention throughout the planning process and beyond. Conjunctive modalities and modifications should be considered and utilized when necessary. Future studies with larger sample sizes, homogenous follow-up periods, and more comprehensive clinical data are needed to substantiate understanding of the response of the condylar segment. CLINICAL RELEVANCE Orthognathic surgeries inevitably alter the alignment and harmony of temporomandibular structures and may result in change of AJS, PJS, SJS, CAA, SRA, and LRA, which may change the biomechanics of joint and lead to several complications like temporomandibular disorders. Especially in cases with midline asymmetry needs special consideration from planning till the end of the treatment to achieve best results. In severe cases, conjunctive modalities and modifications and other alternatives such as inverted-L osteotomies should be considered.

Abstract
The purpose of this study was to evaluate, using cone-beam computerized tomography (CBCT), the rate of sinus membrane perforation in osteotome sinus floor elevation (OSFE) performed with and without a graft material. Thirty patients with 52 OSFE sites were included in the study. Patients were divided into the control group (OSFE performed without graft material) and test groups (OSFE performed with autograft or xenograft). The autograft was harvested from the maxillary tuberosity using bone forceps. The xenograft was a commercial product originating from bovine bone. Graft volume was measured using the water displacement method. CBCT was performed at the initial examination and immediately after surgery to measure the residual bone height and to evaluate the endo-sinus bone gain and membrane perforation. The rate of sinus membrane perforation was 15.4%. Of the 52 OSFE procedures, 26.9% were performed without grafting and 34.6% and 38.5% were performed with autografts and xenografts, respectively. Membrane perforation was significantly higher in the autograft group (P = .033). The median volume of graft materials was 0.3 mL. The difference in graft volume between the autograft and xenograft was not statistically significant (P = .768). The mean endo-sinus bone gain was 6.55 mm in patients without membrane perforation and 8.71 mm in patients with membrane perforation; this difference was statistically significant (P = .035). The volume and physical properties of graft materials are important factors in membrane perforation. Further clinical studies with larger and standardized samples are needed to confirm the effect of graft materials on sinus membrane perforation in OSFE.

Abstract
This study was designed to evaluate the effects of different maxillary movements performed in Le Fort I surgery on the anatomy of the nasal cavity and maxillary sinus, occurrence of rhinosinusitis, and nasal airflow. Patients were divided into three groups: group I underwent pure advancement, group II underwent advancement with yaw rotation, and group III underwent advancement with impaction movements. All evaluations were performed using pre- and postoperative computed tomography images and surveys. Twenty-eight patients were enrolled. The mean pre- and postoperative nasal air volumes in group I were 22.74 ± 6.32 cm3 and 25.17 ± 6.19 cm3, respectively, showing a significant increase (P = 0.041). The mean pre- and postoperative maxillary sinus air volumes were 33.94 ± 13.72 cm3 and 26.28 ± 14.12 cm3 in group II and 35.29 ± 9.58 cm3 and 28.65 ± 8.42 cm3 in group III, respectively, showing significant reductions (P = 0.028 and P = 0.007, respectively). For all movements, the occurrence of septum deviation and nasal airflow impairment was not statistically significant. Pure maxillary advancement movement enhanced nasal cavity air volume. The yaw rotation movement significantly increased quantitative clinical rhinosinusitis symptoms. The risk of airflow impairment following Le Fort I surgery is low.

Abstract
PURPOSE The present study evaluated the potential bone regeneration capacity of combining melatonin and simvastatin, with a goal of producing more osteogenic bone substitutes. MATERIALS AND METHODS A total of 48 male Wistar rats were randomly divided into 4 groups. The following were administered into critical-sized calvarial defects of the rats: Group I-human allograft; Group II-human allograft + 10 mg melatonin; Group III-human allograft + 0.1 mg simvastatin; and Group IV-human allograft + 10 mg melatonin + 0.1 mg simvastatin. Histopathologic, histomorphometric, and microcomputed tomographic evaluations were performed postprocedurally at 4 and 8 weeks. A P value < .05 was considered significant for all evaluations. RESULTS Groups II and III had significantly superior regeneration compared to Group I at weeks 4 and 8. Group III had significantly superior regeneration compared to Group II, particularly in week 4. Group IV had significantly superior regeneration compared to all groups at week 8. CONCLUSIONS The local administration of melatonin and simvastatin resulted in increased new bone mass and quality of bone microstructure than was seen in the control group. Simvastatin shortened the defect regeneration time more effectively than melatonin did. The combined use of melatonin and simvastatin provided a synergic effect on bone regeneration, particularly in the late phase of healing.

Abstract
This study sought to determine the rate of sinus membrane perforation in patients undergoing crestal sinus grafting, as well as the effect of Schneiderian membrane thickness and residual bone height (RBH) on membrane perforation, using cone beam computed tomography. The study included 25 patients undergoing 44 crestal sinus grafting procedures. The sites for crestal sinus grafting were divided into a control group (RBH≥5mm) and a test group (RBH<5mm). All sinus grafting procedures were also categorised based on membrane thickness: group A (<1mm), group B (1-2mm), and group C (≥2mm). The rate of membrane perforation was 18.2%. The median RBH measurement was 5.59mm. No statistically significant difference in membrane perforation rate was found between the test and control groups (P=0.262). The median thickness of the Schneiderian membrane was 1.35mm. There was no statistically significant difference in membrane perforation among the three membrane thickness groups (P=0.431). No significant correlation between RBH and membrane perforation was observed, although clinical observation indicated that there was a tendency for an increased membrane perforation rate in the presence of a RBH<5mm. The perforation rate was found to be at its highest when the membrane was thinner than 1mm.

Abstract
PURPOSE Recombinant human hyaluronidase (rHuPH20) is widely used as a spreading factor, which enhances the absorption of subcutaneously injected medicines. The anti-inflammatory and anti-edema effects of the enzyme were demonstrated in previous studies. In the present study, the anti-edema effect of rHuPH20 was compared with that of dexamethasone in a traumatic rat paw edema model. MATERIALS AND METHODS Twenty-four Sprague-Dawley rats (weight 200 to 450 g) were divided into 3 groups: control (group 1), rHuPH20 (group 2), and dexamethasone (group 3). Traumatic edema was induced in the right hind paws of the rats using Feeney's weight-drop model. After edema induction, 0.4 mL of rHuPH20 (100 U/kg = 0.88 μg/kg dose) and 0.4 mL of dexamethasone (0.5 mg/kg dose) were injected into the right hind paws of the rats in groups 2 and 3. The paw volumes were measured before edema induction and at 3, 6, 12, 24, 48, and 72 hours after induction using a plethysmometer. The Mann-Whitney U test was used for the statistical analyses. Probabilities < .05 were accepted as statistically significant. RESULTS The between percentage change in the edema mean values of groups 1 and 3 showed no significant difference at all time points; however, group 2 showed significantly less change in the edema mean values at 3, 6, 12, 24, and 48 hours after edema induction (P < .05) compared with group 1. The change in the edema mean value for group 2 was significantly less than that for group 3 at 3, 6, 12, 24, and 48 hours after edema induction (P < .05). CONCLUSIONS Local rHuPH20 injection more effectively reduced the edema that was induced traumatically in rat paws than did dexamethasone. However, further clinical studies are needed regarding the use of rHuPH20 as a postoperative anti-edema agent in place of dexamethasone.

Abstract
Q fever is a zoonotic disease that occurs worldwide and is caused by the obligate intracellular bacterium Coxiella burnetii. The aim of this study was to investigate the presence of C. burnetii infection in aborted sheep in eastern Turkey using PCR. A total of 200 fetuses were collected from aborted sheep belonging to 200 herds in different locations in the eastern part of Turkey. Foetal organ samples such as liver, spleen, lung and stomach were taken and the DNA was purified from two hundred pooled samples. PCR analysis of C. burnetii presence in infected organs was performed, and 4 samples (2%) were found positive. In addition, the pooled organ suspensions were inoculated to embryonated chicken eggs, and PCR analysis of yolk sacs showed C. burnetii DNA in 5 samples (2.5%). This study shows that C. burnetii infection has an important role in sheep abortions in eastern Anatolia region.

Abstract
The present study aims to present a case of a subungual glomus tumour with literature to the findings on magnetic resonance (MR) imaging. A 51-year-old man consulted his physician because of a pain in the nail bed of his thumb, which he had had for 2 years. A plain radiography and MR examination was performed. Physical examination showed a blue-brown focus beneath the nail and there was deformation. A plain radiography demonstrated no abnormality. T1-weighted spin-echo images showed a well-marginated, oval, slightly hyperintense lesion (4 mm diameter) located in the subungual region. On turbo spin-echo T2-weighted images the lesion was hyperintense with a hypointense rim. T1-weighted spin-echo images after intravenous administration of contrast medium showed strong enhancement. The lesion was completely excised at surgery and the diagnosis of a glomus tumour was established histologically. In conclusion, MR imaging offers excellent diagnostic information about a clinically suspected glomus tumour.

Abstract
In this study; the parasite prevalence of schools with different socio-economical status and three methods for diagnosing intestinal parasitosis were evaluated. Children from two primary schools and one junior high school with different socio-economical status participated in the study. The three method used for diagnosing parasitosis in this study were direct wet mounts, concentrated saline flotation technique, and zinc sulfate centrifugal flotation method. Parasitosis was found in 69 fecal samples (18%). The distribution of the parasites found were Hymenolepis nana (29%), Ascaris lumbricoides (26%), Enterobius vermicularis (23%), Trichirus trichiura (18%), taenia saginata (4%). The parasite prevalence in schools with low and high socioeconomical status differed significantly (27% vs. 5% respectively). Combined methods were superior to single methods. The combined method of direct wet mounts and zinc sulfate centrifugal flotation was the most sensitive method (diagnosis rate 90%). But we think that the combined method of direct wet mounts and concentrated saline flotation technique is a simpler method with almost equal results (86%).
