Characteristics and Surgical Management of Bilateral Body Mandibular Fractures: A 23-Year Experience.
J Clin Med

Division of Maxillofacial Surgery, Surgical Science Department, Città della Salute e della Scienza Hospital, University of Turin, 10126 Turin, Italy.
: Mandibular fractures are among the most common facial injuries. Bilateral fractures of the mandibular body region (BBMFs), however, are rare. The aim of this retrospective study was to analyze the characteristics, surgical management, and outcomes of BBMFs in a third-level trauma center in northern Italy.

Penetrating orocutaneous or oropharyngeal fistulas (POFs), severe complications following unsuccessful oral or oropharyngeal reconstruction, remain complex clinical challenges due to lack of supportive tissue, contamination with saliva and chewed food, and dynamic oral environment. Here, we present a Janus hydrogel adhesive (JHA) with asymmetric functions on opposite sides fabricated via a facile surface enzyme-initiated polymerization (SEIP) approach, which self-entraps surface water and blood within an in-situ formed hydrogel layer (RL) to effectively bridge biological tissues with a supporting hydrogel (SL), achieving superior wet-adhesion and seamless wound plugging. The tough SL hydrogel interlocked with RL dissipates energy to withstand external mechanical stimuli from continuous oral motions like chewing and swallowing, thus reducing stress-induced damage.

Division of Restorative Dentistry, Periodontology and Prosthodontics, Department of Dental Medicine and Oral Health, Medical University of Graz, Billrothgasse 4, 8010, Graz, Austria.
Objective: To introduce a novel digital technique for precise assessment of peri-implant bone heights, enhancing accuracy and objectivity in dental implantology research.
Methods: This study utilized digital intraoral scans and digitized impressions obtained during implant exposure surgery, combined with computer-aided design (CAD) software, to measure peri-implant bone heights accurately during flap-raising procedures. The peri-implant bone measurements were quantified circumferentially and validated through a comparative analysis of intraoral and extraoral scans.
Effectiveness of intra-oral botulinum toxin injection in comparison to the extra-oral approach on pain and quality of life in patients with myofascial pain: a randomized clinical trial.

Objective: To evaluate and compare the effectiveness of the ultrasound-guided intra-oral and extra-oral transcutaneous injection techniques on the clinical outcome variables in patients with myofascial trigger points within the masseter muscle.
Materials And Methods: This prospective randomized trial included 42 patients diagnosed with myofascial pain. Patients were randomly allocated into one of two groups based on the technique of trigger point injection: intraoral and extraoral injection technique groups.

Article Synopsis
- Temporomandibular disorders (TMD) are a leading cause of orofacial pain, with hyperactivity of the lateral pterygoid muscle (LPM) often implicated; botulinum toxin A (BTX) injections into this muscle can be a treatment but lack standardization.
- A study conducted on five cadavers using extraoral landmark-based LPM BTX injections revealed a 0% accuracy rate and significant neurovascular disruption in 40% of cases.
- The findings underline the dangers of blind BTX injections for TMD and emphasize the need for improved treatment protocols, including the use of guided imaging techniques.
