Preoperative virtual surgical planning and the use of 3D-printed patient-specific models and cutting guides are increasingly being used in the reconstruction of mandibular defects with a free bone flap. This technology offers several advantages over conventional surgery, such as reduced operating time, reduced bone flap ischaemia time, and the ability to perform more complex and precise reconstructions. This review presents the evidence supporting 3D-assisted surgery for mandibular defect reconstruction and discusses the utilisation of commercial vendors versus in-house 3D-printing solutions.

Effects of adjuvant hyperbaric oxygen therapy and real-time fluorescent imaging on deep sternal wound infection: a retrospective study.
J Wound Care
January 2025
Division of Plastic Surgery, Integrated Burn & Wound Care Center, Department of Surgery, Shuang-Ho Hospital, New Taipei City, Taiwan.
Objective: Deep sternal wound infection (DSWI) is a rare but devastating complication that is estimated to occur in 1-2% of patients after median sternotomy. Current standard of care (SoC) comprises antibiotics, debridement and negative pressure wound therapy (NPWT). Hyperbaric oxygen therapy (HBOT) appears to be an effective adjuvant therapy for osteomyelitis.

Introduction: Distant recurrences are a major problem after surgical treatment for endometrial carcinoma; metastases to the bone are usually restricted to the axial skeleton, cases of costal localization are few. We present a case of a massive costal metastases successfully treated in our department.
Case Presentation: A 60-year-old woman underwent bilateral hysteroannessectomy followed by adjuvant radiotherapy for endometrial adenocarcinoma pT3a FIGO IIIA.
Novel Reconstruction Method Using the Double-Arm Vascularized Fibula Flap and TriLock Bridging Plate System for Segmental Mandibulectomy Including the Anterior Border of the Mandibular Ramus.
J Craniofac Surg
January 2025
Department of Plastic and Reconstructive Surgery, Saitama Medical University International Medical Center.
This study aimed to develop a novel reconstruction method for segmental mandibulectomy. In the authors' opinion, reconstruction of the anterior border of the mandibular ramus using a double-arm vascularized fibular flap is important to prevent deformity due to buccal depression and the accumulation of food debris, thereby eliminating masticatory dead space that cannot be filled with prostheses such as implants or dentures. Using conventional reconstruction plates, the reconstructed bone positioned at the anterior border of the mandibular ramus required either fixing with only 1 screw or using 2 plates for stable fixation, making it difficult to position the plates stably.

Department of Pediatrics Dentistry and Orthodontics, Faculty Odonto-Stomatology, Can Tho University of Medicine and Pharmacy, Can Tho City, Vietnam.
Aim: This study aimed to evaluate the impact of a combination of immediate implant placement with maxillary sinus augmentation (MSA) solely using platelet-rich fibrin (PRF) on guided bone regeneration.
Materials And Methods: An interventional before-after (pre-post) study design was used with 30 dental patients (≥18 years of age; 14 males and 16 females) with initial bone heights ranging between 4 and 6 mm. Following the general check-up and the creation of a study model, the planned implant location demonstrated an external right maxilla diameter of more than 5 mm, thereby validating the cone-beam computed tomography (CBCT) radiograph.
