Cone-beam computed tomographic analysis of maxillary sinus septa among Yemeni population: a cross-sectional study.

BACKGROUND: Maxillary sinus septa increase perforation risk of Schneiderian membrane during the sinus floor elevation (SFE). Cone Beam Computed Tomography (CBCT) allows for a more precise assessment of the septal position; thus, preoperative CBCT analysis is substantial to avoid possible complications. This study aims to investigate the 3D characteristics of the maxillary sinus septa based on CBCT images. To our knowledge, no study reported the CBCT-based investigation for the sinus septa among Yemeni population. MATERIALS AND METHODS: This is a retrospective cross-sectional analysis of 880 sinus CBCT images 440 patients. The septa prevalence, locations, orientations, morphology, and associated factors were analyzed. The effect of age, gender, and dental status on the sinus septa and the relationship between sinus membrane pathology and sinus septa were also analyzed. Anatomage (Invivo version 6) was used for CBCT images analysis. Descriptive and analytical statistics were performed, and a P-value < 0.05 was significantly considered. RESULTS: The maxillary sinus septa were found among 63.9% of patients and 47% of sinuses. The average septa height was 5.2 mm. 15.7% of patients had septa in the right maxilla, 18% in the left, and 30.2% in both. Gender, age, and dental condition had no influence on the presence of septa, and septa presence did not influence sinus membrane pathology. Many septa originated from the floor (54.5%), located in the middle (43%), with coronal orientation (66%) and complete configuration (58.2%). CONCLUSION: Based on our findings, the septa prevalence, locations, orientations, and morphology were significant and equivalent to the highest recorded in the literature yet. Thus, when sinus floor elevation is planned, CBCT imaging of the maxillary sinus is recommended for safe dental implantation.

Assessment of quality of life in patients treated for orbital fractures.

PURPOSE: This study aimed to assess the quality of life (QOL), before and after surgery, of patients who underwent open reduction and internal fixation for orbital fractures. STUDY DESIGN: A prospective study. PARTICIPANTS AND SETTING: The self-report outcome measures of 50 patients treated at the Department of Oral and Maxillofacial Surgery of the Second Affiliated Hospital of Jiamusi University from January 2016 to June 2019 were prospectively collected. MAIN MEASURES: The quality of life was assessed using four patient-reported outcome measures (PROMs): the 15D questionnaire, Oral Health Impact Profile-14 (OHIP-14), Hospital Anxiety and Depression Scale (HADS), and 36-item Short Form Survey (SF-36). Both descriptive and comparative data analyses were calculated. RESULTS: Zygomaticomaxillary complex fractures were the most encountered (40.3%). The total OHIP-14 scores before and after treatment were 1.72 and 1.68, respectively. Vision, breathing, sleeping, eating, usual activities, discomfort and symptoms, and vitality showed minimal changes in the 15D questionnaire. The HADS scores were ranged from 0 to 7, indicating no anxiety or depression. The comparison of SF-36 scores after 3 months and after ≥6 months of treatment revealed no significant difference. CONCLUSIONS: Patients' QOL was minimally impacted by orbital fractures and their treatments. The severity of the negative impact can be minimized if appropriate management strategies are taken.
