Serial lateral cephalograms and three‑dimensional scans obtained preoperatively, immediately postoperatively, and at follow‑up (mean 1.4 years) were used to quantify total and regional pharyngeal airway volume changes and mandibular relapse, defined as sagittal point B displacement. Demographic characteristics, surgical movements including setback magnitude and SN-MP rotation, osteotomy type, genioplasty, treatment approach, and baseline airway dimensions were incorporated as covariates. Correlation analyses and multivariable linear regression assessed associations between airway changes and relapse while controlling for potential confounders. The mean mandibular surgical movement was -6.32 ± 8.72 mm. There was no significant reduction in total airway volume immediately after surgery or at follow-up, and no significant mandibular relapse occurred. Also, no significant correlation was detected between airway changes and relapse in either immediate postoperative period or follow-up period, whereas greater mandibular setback independently predicted forward relapse (β = -0.64, P < 0.001).

A retrospective cohort study was conducted on patients who received zygomatic implants from the year 2007 to 2024 at Rajan Dental Institute, Chennai, India. Data collected from digital archives were evaluated to calculate the cumulative survival rates of zygomatic implants. Patient-reported outcome measures (PROMs) on comfort, speech, esthetics, self-confidence, and overall satisfaction were assessed using a Likert-scale questionnaire. A total of 449 patients were rehabilitated with 945 zygomatic implants. Of these, 382 patients rehabilitated with 801 zygomatic implants were included in the study who met the inclusion criteria. The mean follow-up was 8.6 ± 4.1 years. Twenty implants failed in 14 patients, yielding a cumulative implant survival of 97.5% and patient-based survival of 96.3%.

PROMs indicated high satisfaction: >90% of respondents reported maximal improvement across all domains. This single-center analysis, with survival rates exceeding 97% over 17 years and excellent patient-reported outcomes, suggests that zygomatic implants provide a predictable and durable solution for severely resorbed maxillae.

Nineteen patients (12 children and seven adults) with clinically and computed tomography-confirmed trapdoor fractures who were surgically treated at the Erasmus Medical Center between 2012 and 2024 and had at least 3 months of follow-up were analyzed retrospectively. The primary outcomes were diplopia and limitation of ocular motility assessed 1 year postoperatively. Secondary outcomes included presenting symptoms, radiological findings, and operative characteristics. Clinical profiles and radiological findings were largely similar between adults and children, including presence of rectus muscle incarceration. Three months after surgery, diplopia was present in 55% of children and 57% of adults. One year postoperatively, one out of 10 children and three out of four adults still reported diplopia, attributable to mild elevation or depression deficits.

The accuracy of a three-dimensionally (3D)-printed guide was compared with an AR system in a phantom study. Preplanned osteotomy lines were cut, and screw holes were drilled, simulating a Le Fort I osteotomy, and its accuracy was assessed by comparing pre- and postoperative computed tomography. Seven maxillofacial surgeons participated, each tasked with drilling 12 screws and performing two osteotomy cuts using either AR or the guide. There was no statistically significant difference in cutting accuracy between AR and the guide, with median errors of 0.71 and 0.72 mm, respectively. However, AR drilling accuracy (1.48 mm) was significantly worse than that of the guide (0.73 mm) and yielding a 75% success rate of AR-drilled holes suitable for patient-specific implant fixation.

Using the preoperative and 1-week postoperative computed tomography scans, the anterior nasal spine displacement, maxillary molar impaction, maxillary advancement, shortest distance from the infraorbital foramen to the maxillary osteotomy line, and infraorbital foramen-to-fixation plate distance were quantified. Trigeminal somatosensory evoked potentials were recorded preoperatively, immediately postoperatively, and 6 months postoperatively to objectively assess infraorbital nerve function. Neurosensory disturbances were defined as postoperative prolongation of infraorbital nerve latency relative to each patient's preoperative baseline. Immediate postoperative neurosensory disturbances were observed in of 49 out of 102 patients (48.0%). Compared with the non-neurosensory disturbance group, the neurosensory disturbance group exhibited greater maxillary molar impaction (P = 0.012) and shorter infraorbital foramen-to-fixation plate distances (P < 0.0001); significant differences were also noted in the trigeminal somatosensory evoked potential-derived sensory threshold (P = 0.042), N45 latency (P < 0.0001), and stimulation intensity (P < 0.0001). Stimulation intensity negatively correlated with the infraorbital foramen-to-fixation plate distance (R² = 0.344; P < 0.0001). All neurosensory disturbances resolved completely within 6 months.
