Background and Objectives: This study aimed to assess the frequency and distribution of facial bone injuries in terms of age, sex, residence, location, and etiology in the north-eastern region of Romania. Materials and Methods: This retrospective study was conducted within the Oral and Maxillofacial Clinics of “Sf. Spiridon” Hospital, Iași. The study group included 701 subjects (mean age 41.02 ± 18.45; sex: 603 males and 98 females) who were diagnosed with an orbital wall disorder. The epidemiological data on orbital wall fractures—including sociodemographic features, etiology, and location—were statistically analyzed. Results: The prevalence of orbital pathology was 1.47% congenital cases, 1.75% tumors, and 96.7% orbital fractures. The distribution of sex, age group, residence, and orbital localization varied significantly among the three diagnostic categories: tumors, congenital conditions, and fractures. Regarding sex, fractures were significantly more frequent in males (87.0%) compared to congenital cases (70.0%) and tumors (41.7%), while tumors showed a female predominance (58.3%) (p < 0.001). Congenital conditions predominantly affected patients under 20 years old (90.0%), whereas fractures were more evenly distributed across age groups, with higher frequencies between 31 and 50 years. In contrast, tumors involving the orbital walls were more frequent in older patients, with 33.3% in the 61–70 age group and 25.0% over 70 years. Regarding orbital localization, fractures were more likely to be bilateral (37.3%) or on the right side (44.3%), whereas congenital orbital defects and orbital tumors were predominantly unilateral and left-sided (70.0% and 66.7%, respectively). Bilateral involvement was rare in congenital cases (10.0%) and absent in tumors. Conclusions: The data support the finding that men are significantly more prone to trauma and orbital fractures, especially as a result of interpersonal violence and accidents, highlighting the need for preventive measures tailored to sex and socio-professional context.

Background: Accurate transfer of the surgical plan is essential in bimaxillary orthognathic surgery, where small discrepancies between planned and postoperative skeletal positions may influence functional and aesthetic outcomes. This study compared the three-dimensional (3D) accuracy and time efficiency of conventional and fully digital planning workflows using CBCT-based evaluation. Methods: This retrospective comparative study included 100 adult patients with skeletal Class II or III malocclusion treated by Le Fort I osteotomy combined with bilateral sagittal split osteotomy (BSSO). Patients were allocated to conventional planning (n = 50) or fully digital planning using IPS CaseDesigner (n = 50). Planned and postoperative CBCT datasets were superimposed using voxel-based cranial base registration. Linear deviations at A-point and Pogonion, total RMS error, planning time, and operative time were analyzed. Results: Mean deviations were lower in the digital group at A-point (1.28 ± 0.28 mm vs. 1.63 ± 0.36 mm) and Pogonion (1.49 ± 0.42 mm vs. 1.95 ± 0.44 mm) (p < 0.001). Total RMS deviation was reduced in the digital workflow (1.39 ± 0.39 mm vs. 1.80 ± 0.54 mm; p < 0.001). Planning and operative times were significantly shorter in the digital group (p < 0.001). Moderate correlations were observed between time variables and 3D deviations. Conclusions: Fully digital planning showed improved 3D accuracy and significantly reduced planning and operative times compared with conventional methods, while maintaining clinically acceptable deviations.

Background: Quality-of-life (QoL) assessment has become an essential component of outcome evaluation in oral and maxillofacial surgery (OMFS), particularly in interventions with functional implications for breathing, sleep, and oro-facial performance. Existing instruments often lack specificity for the postoperative OMFS population. This study aimed to develop and psychometrically validate the OMFS-QoL-18 questionnaire, a condition-oriented patient-reported outcome measure designed for postoperative assessment. Methods: A cross-sectional validation study was conducted on 226 adult patients evaluated 6–12 months after orthognathic or function-oriented OMFS procedures. Internal consistency was assessed using Cronbach’s alpha, and reproducibility using the intraclass correlation coefficient (ICC) based on a two-way random-effects model with absolute agreement. The internal structure of the instrument was explored through an exploratory dimensionality analysis using Principal Component Analysis (PCA), including Kaiser–Meyer–Olkin (KMO) testing and Bartlett’s test of sphericity. Descriptive statistics were calculated for item and domain scores. Results: The OMFS-QoL-18 demonstrated good internal consistency (Cronbach’s α = 0.789; standardized α = 0.783) and satisfactory reproducibility (ICC = 0.81; 95% CI: 0.74–0.87). The exploratory dimensionality analysis suggested a multidimensional structure, with five components explaining 67.1% of the total variance. Item clustering was broadly consistent with the predefined conceptual domains, including respiratory comfort, sleep quality, daytime function, oro-maxillofacial function, and global satisfaction. Given the use of PCA as a component-based method, these findings are interpreted as preliminary evidence of dimensional organization rather than confirmation of latent constructs. Conclusions: The OMFS-QoL-18 demonstrated good internal consistency and preliminary evidence of a coherent factor structure. These findings support its use as a promising condition-specific instrument, pending further validation studies. Further multicenter and longitudinal validation studies are warranted to confirm structural stability and responsiveness over time.
