Objective: the aim of this study was to evaluate the efficacy of ultrasonography in diagnosis of tempromandibular joint soft tissue injury after mandibular osteosynthesis. Material and Methods: ten male patients (20 joint) with age ranged between 20-28 years were collected from those attending the outpatient clinic of Oral and Maxillofacial Surgery Department, Al-Kuwait Hospital, Sana'a University. Patients were divided into two groups according to the number of fracture line in the mandible. All patients were randomly assigned to diagnosis of the soft tissue changes of temporomandibular joint by either ultrasonography or magnetic resonance image preoperatively, after 2 weeks and 3 months postoperatively. Results: preoperatively, there was moderate agreement between ultrasonography and magnetic resonance image in the diagnosis of abnormal findings in both groups, the difference was not statistically significant. In group I, ultrasonography of the temporomandibular joint didn't detect any abnormal findings after mandibular osteosynthesis, meanwhile, magnetic resonance image recorded abnormal findings 40% and 20% after 2 weeks and 3 months respectively. In group II, the diagnosis of abnormal findings was the same (80%) pre and postoperatively by using magnetic resonance image however, the percent of abnormal findings was reduced from 60% preoperatively to 40% postoperatively by using ultrasonography. Conclusion: the ultrasonographic image was not able to identify or diagnosis the disc position changes after indirect trauma. However, it had to some extent a role in the identification and diagnosis of effusion in temporomandibular joint.
The aim of this study was to discuss the significance of microplate osteosynthesis in pediatric mandibular fractures. Patient and methods: Ten patients with age ranged between 1-10 years were collected from those attending the outpatient clinic of Oral and Maxillofacial Surgery Department, Al- kawait Hospital, Sana’a University. All patients that have mandibular trauma associated with either single or multiple fracture lines in the mandible were included in this study. Diagnosis of the mandibular fracture was achieved through history, clinical and radiographic examinations. All patients were treated by open reduction and internal fixation by 1.2mm microplate. Results: No signs of infection in or around the incision during fracture treatment were observed, and the soft tissue healing progressed normally. Clinical follow up was done every other day for two weeks and after three months postoperatively. Conclusion: Management of mandibular fracture in children by open reduction and microplate is an acceptable method for treatment with least morbidity and increase stability of displaced segment.
Aim of this study: It was to determine the prevalence of Mandibular Incisive Canal (MIC) among a sample of Yemeni adults obtained from Cone-beam Computed Tomography (CBCT). Materials and Methods: This is a retrospective descriptive cross-sectional study which is conducted in Yemen to evaluate CBCT images of 180 subjects, 360 sides were evaluated respectively. The samples were 74 males (41.1%) and 106 females (58.9%). Result: Of the 180 subjects and 360 sides, 167 right (92.8%) and 171 left (95%) Sides were found to have MIC. Among these subjects, 166 (96.5%) had MIC bilaterally and 6 (3.5%) were unilaterally. According to gender, females were (98.1%) and males (91.9%), while among age groups ≤ 40 years (94.3%) and > 40 years (97.3%) were found to have MIC. The mean height of MIC was 1.77 ±.45mm and the mean width was 1.66 ±.44 mm. The mean length of MIC was 12.74 ±4.4 mm. The mean distance from MIC to the alveolar process was 16.77 ±4.06 mm and to the inferior border of the mandible was 8.61 ±1.9 mm. The mean distance from MIC to the labial bony surface was 3.12 ±1.09 mm and to the lingual bony surface was 4.35 ±1.5 mm. All the mean values of the linear measurements were slightly higher in males than that of females. There were statistically significant differences in D3, D5 & D6 between genders and in D3, D4 & D5 between ages (P < 0.05). But there was no statistically difference between sides. Conclusion: The MIC is present with a significant percentage of 95.6 % of Yemeni adults, which emphasizes the need to raise the awareness of MIC position and configuration among general practitioners and maxillofacial surgeons.
The aim of this study was to evaluate the prevalence of dry socket at the faculty of dentistry in Sana’a University. Patient and methods: 994 patients attended to the Oral Surgery Clinic in the faculty of Dentistry, Sana'a University, to have their teeth extracted in period from October 1, 2022 to January 19, 2023. 26 patients with dry socket were analyzed who underwent tooth extraction. Results: The percentage of the patients who had a dry socket was 2.6%. The percentage of male to female was 1:1.3. According to age the dry socket was more in age between 18-30 years. Conclusion: The incidence of dry socket was more happened in young adult, female, single tooth in mandible and with patients taking non-steroidal anti-inflammatory drugs before extraction.
