Recently, interest has increased in non-pharmacological methods to reduce anxiety, such as auditory stimulation. This randomized controlled trial evaluated the effects of binaural beats (BB) and isochronic tones (IT), two forms of auditory stimulation, on dental anxiety and physiological parameters during impacted mandibular third molar surgery. Ninety patients were assigned equally to BB, IT, and control (no intraoperative auditory stimulation) groups. Anxiety levels were assessed using the MDAS, DFS, STAI-S, and a visual analogue scale pre- and postoperatively. The BB and IT group patients also completed a satisfaction questionnaire. Physiological parameters (respiratory rate, pulse rate, blood pressure [SBP, DBP], oxygen saturation) were recorded at eight surgical stages. No significant between-group differences were observed in the pre- or postoperative anxiety questionnaire scores. Isolated between-group differences in physiological parameters were observed: mean SBP at incision was lowest in the BB group (P = 0.041), while mean respiratory rate at anaesthesia was lowest in the IT group (P = 0.015). The majority of BB and IT group patients (78.3%) reported that they would prefer auditory stimulation in future dental treatments. The findings indicate that BB and IT have a limited effect on reducing dental anxiety during impacted mandibular third molar surgery and do not support a definitive anxiolytic benefit. Auditory stimulation may transiently influence certain stress-related physiological responses; however, further studies using objective neurophysiological measures and standardized protocols are required to clarify their role in oral surgery.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148498590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meta-analyses were performed using a random-effects model to calculate pooled prevalence rates. The pooled prevalence of TBP was 62.5% (95% confidence interval (CI) 53.6-70.7%), while the prevalence rates of PAT and PGF were 26.1% (95% CI 15.4-40.6%) and 28.6% (95% CI 18.7-41.2%), respectively. Multilocular patterns predominated over unilocular, and grade 2 extension (pneumatization between the glenoid fossa and crest of the articular eminence) was the most frequent extension type in PAT.

Presented here is a case series of orbital and functional outcomes using polyetheretherketone (PEEK) implants and cutting guides to describe a tertiary centre's practice of using custom reconstruction to assist in improving orbital symmetry with the aim of functional improvement in symptomatic diplopia. Between June 2020 and October 2023, 13 consecutive adult patients with SOM were managed surgically by resection and custom reconstruction. Retrospectively, for each patient, clinical data including Hertel difference (HD) and orbital volume difference (OVD, the comparison of affected and unaffected orbital volumes) were collected and compared preoperatively and postoperatively. The series had a mean follow-up of 21 months. Preoperatively, 10 patients had proptosis or diplopia, and nine patients had improvement postoperatively. The mean Hertel differences improved from 4.3 mm (range 0-7 mm) preoperatively to 2.1 mm (range 0-5) postoperatively (P = 0.01). The mean OVDs increased from 1.9 cm3 (range 0.3-4.1 cm3) preoperatively to 2.4 cm3 (range 0.3-4.8) postoperatively (P = 0.30). In the authors' experience, using PEEK for custom reconstruction is a safe and effective way to improve globe position, measurable using a Hertel exophthalmometer and visual symptoms.

Non-syndromic unicoronal craniosynostosis commonly leads to facial asymmetry. This study aimed to quantify changes in facial asymmetry before and after surgical treatment using an automated 3D technique. A retrospective study was performed including 32 patients treated at Radboud University Medical Center Nijmegen between 2011 and 2024. Pre- and postoperative three-dimensional facial photographs were analysed, and asymmetry was quantified using regional root-mean-square (RMS) values. Patients were treated with either minimally invasive endoscopic-assisted craniosynostosis surgery (EACS) or open cranial vault reconstruction (OCVR). In the EACS group, the mean ages at preoperative and postoperative imaging were 4.4 ± 2.0 and 14.4 ± 3.3 months, respectively, while in the OCVR group these were 9.0 ± 3.2 and 21.3 ± 5.5 months. Facial asymmetry significantly decreased after surgery across all regions (P < 0.001). Overall RMS values decreased from 3.36 mm preoperatively to 2.44 mm postoperatively after EACS and from 3.33 mm to 2.46 mm after OCVR, corresponding to a reduction of 27-29% (P < 0.001). The greatest improvement was observed in the upper facial region, with a mean reduction of 1.47 mm (P < 0.001). In conclusion, surgical treatment of unicoronal craniosynostosis results in a substantial reduction of facial asymmetry, particularly in the upper face, with comparable improvements for both surgery groups.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148451062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the study was to identify any association between facial fractures and the long-term risk of hospitalization for mental health disorders. The study followed a cohort of 64,089 patients aged ≥10 years who were hospitalized for facial fractures between 1989 and 2023 in Quebec, Canada. Patients with facial fractures were matched to 318,520 controls based on age, sex, and year, and facial fractures were classified by site, type, and cause. The outcomes were hospitalizations for psychiatric disorders, substance use disorders, and suicide attempts up to 34 years later. Stratified Cox regression models were used to estimate adjusted hazard ratio (HR) and 95% confidence interval (CI) for the association between facial fractures and mental health hospitalization. Compared with matched controls, patients with facial fractures were 1.58 times more likely to be hospitalized for a mental health disorder over time (95% CI 1.55-1.61). Mandible (HR 1.89, 95% CI 1.81-1.96), open (HR 1.75, 95% CI 1.63-1.88), and assault-related facial fractures (HR 2.43, 95% CI 2.33-2.54) were most strongly associated with subsequent mental health hospitalization. Patients with facial fractures were at risk of admission for psychiatric disorders (HR 1.35, 95% CI 1.32-1.38), substance use disorders (HR 2.12, 95% CI 2.07-2.18), and suicide attempts (HR 1.69, 95% CI 1.58-1.80).

Follow-up duration and assessment methods varied considerably across studies. The available literature is characterized by small sample sizes, heterogeneous techniques, and inconsistent outcome reporting. Within these limitations, both NPC obliteration and repositioning have been described with high short- to mid-term implant survival, although neurosensory outcomes were variably reported.
