The zygomatic arch is the most prominent portion of the face and is commonly injured during facial trauma. It articulates with the frontal bone, temporal bone, maxilla, and sphenoid bone, and serves as the main bridge amongst these bones. Isolated arch fractures comprise 10% of all zygomatic fractures and 5% of all facial bone fractures. Treatment of zygomatic arch fractures varies from observation to open reduction. The Gilles temporal approach is a commonly used surgical technique for the reduction of zygomatic arch fractures. However, this surgical approach is associated with a facial scar in the hairline and risks of facial nerve palsy. In this research, we performed a new method using a fifty millimeter needle without surgery cut for replacement of broken zygomatic arch and evaluated the amount of pain, edema, maximum mouth opening, and ecchymosis before and after the surgery.

CT scans were taken of all the patients with isolated zygomatic arch fracture who were referred to Imam Reza Medical Center and department of maxillofacial surgery during 2019-20. The 50 mm needle was used for reduction with the new method.

This study was performed on 7 patients with isolated fractures of zygomatic bone. The mean age of patients was 33.85. 5.87 years. Significant reduction in pain was reported during 7 days after surgery, but the rate of edema (p = 0.539) and the amount of mouth opening after surgery did not show a significant difference.

In reviewing the above studies and comparing them with the present study, it was observed that in simple fractures, the surgical method of the present study was a very useful and uncomplicated method in patients. Despite open reduction methods, these methods have a lower scar rate, the duration of surgery is reduced, and this can lead to faster recovery of the patient.

The main purpose of this study is to compare the body image and life satisfaction among the patients whom undergone cosmetic surgery or candidate for the surgery in the department of maxillofacial surgery, Imam Reza Hospital of Tabriz.
This study is a retrospective case control research. 90 cases were included in this study from both genders randomly. Cases of each group included in this study were selected either from candidates or who underwent maxillofacial cosmetic surgery in Imam Reza Hospital of Tabriz. (2015-2018). The multi-dimensional questionnaire of individual attitude toward their body image (MBSRQ) and Dayner and Part Life Satisfaction Questionnaire (SWLS) were used for data collection. For data analysis, descriptive statistics and multivariate analysis of variance (MANOVA) and independent t-test were used. The results of multivariate analysis of variance analysis (MANOVA) and independent t-test shows that body image and its components between the patients underwent the surgery and candidates of cosmetic surgery is not significantly different. However the life satisfaction in candidate of cosmetic surgery who didn’t undergo the surgery is significantly higher with 95% confidence interval in comparison to the other the group

Most people fail to have necessary dental care because theyre anxious to go to the dentist due to lack of the knowledge about dental procedures .The aim of this study was to evaluate the effect of verbal explanation in reduction of dental stress before third molar operation.
This study designed as controlled clinical trial. Totally 60 patients selected from those referred to the oral and maxillofacial surgery department, dental faculty of Tabriz. After verbal expranation, the questionnaire consisted of demographic characteristics (age, education, life status, number of dental visits before surgery) and mean of pain according to visual analogue scale (VAS) was recorded. Data were analyzed by descriptive statistics (mean ± SD), T-test and chi-square test by using SPSS.20 (P Based on VAS scale, the mean of stress in control group was higher than test group (5.91vs. 4.22 before surgery) and (5.61 vs. 3.115 after surgery) (P Verbal explanation can reduce the stress level in patients undergoing third molar operation.

Inferior alveolar nerve block (IANB) is commonly applied for anesthesia of lower jaw but because of its anatomical location. The success rate of IANB is low. According to the fact that most of patients have radiography when refer to the dentists, we compared the success rate of anesthesia with or without using radiography to make IANB. In this study the patients referred to the maxillofacial department of Tabriz faculty of dentistry between 2011-2012 were included. At the first stage IANB was performed without using radiography and at the second stage we used radiography. Finally the success rate of this two methods were compared. Thirty one (12 female -19 male) patients with mean age of 37.16±10.47 were included in this study. We found statistically significant difference between the success rate of this two methods (p=0.02). Using radiography significantly success rate of IANB injection.

Backgrounds and Dry socket is a painful disabling condition almost following dental extractions. Given the high prevalence of this complication، many researchers have tried to find successful methods to prevent its occurrence. The purpose of this study is was to evaluate the effect of Gelatamp in prevention of dry socket. In this study 65 subjects with two impacted third molars in mandible were selected. Teeth were removed by conventional method and Gelatamp was inserted in one of the sockets randomly. All patients examined clinically four days after the surgery and obtained data were analyzed statistically. From total number of 57 subjects two subjects after Gelatamp application (22. 2 %) and seven subjects in the controls (77. 8 %) experienced dry socket. The difference between two groups was not significant (p = 0. 08). Gelatamp could be an effective strategy in the prevention of dry socket after mandibular impacted third molar removal.

Mucormycosis is a highly aggressive fungal infection which has the most aggressive behavior among all fungal infections. This infection typically affects immunocompromised patients and is rare in healthy individuals. Foreign bodies in open injuries may serve as the most common feature of mucormycosis infection in healthy patients. Early diagnosis is essential for successful treatment. Her, we report mucormycosis in a 52-year-old female without any systemic disease, with the history of an extraction of a maxillary first molar for about one month ago. Signs and symptoms included pain in the socket, swelling in maxillary alveolus with diffuse erythema, discharge in the socket, necrotic and exposed bone. In histopathological study, mucormycosis was reported. The patient was treated with debridement, fluconazole, nutritional support and hydration which resulted in patient’s recovery. Foreign bodies like dental calculus and delayed epithelialization in the socket may be considered as the predisposing factors in this case.

Impacted third molar surgeries are common in dental settings. Post-operation complications including pain and dry socket are also common. Reducing these complications is one of the necessities in oral surgeries. Although a few studies have found prophylactic metronidazole as an effective means of preventing dry socket, in most of these studies interventional factors have not been controlled properly. Therefore, the present study was aimed at evaluating the effect of metronidazole on prevention of pain and dry socket after controlling the interventional factors. A clinical trial was conducted in double-blinded manner on 42 patients with two mandibular impacted third molars. In each subject, both third molar teeth in mandible were selected, one as control. In case group, metronidazole gel (25%) was placed in the socket after tooth extraction. All operations were carried out by one oral surgeon under same circumstances. Demographic data, and pain and dry socket were evaluated by clinical examination and completing questionnaires 4 days after surgery. The interval between two surgeries was at least one month. The data were statistically analyzed by SPSS and Fisher’s exact test. Four days following surgery, 3 subjects in the case group (3.6%) and 5 subjects in the control group (6%) experienced dry socket. There was no statistically significant difference between the cases and controls (P=0.72). Metronidazole gel (25%) placement in the socket is not efficient in reducing complications after surgical removal of third molars.
