AI Article Synopsis
Article Abstract
Background: The recent increase in computer-aided design and computer-aided manufacturing (CAD/CAM)-assisted surgery has warranted a thorough evaluation of the accuracy of virtual plan execution. Mandibular reconstructions with a fibula free flap were evaluated by comparing the fibular segments postoperatively with the virtual surgical plans.
Methods: This study included computed tomography data for 20 patients (11 males; mean age 61.3 years, range 47-74) that received a mandibular reconstruction with a fibula free flap. Linear distances (superior and inferior borders) of 41 fibula segments and intercoronoid distances were measured.
Results: The mean difference was 3.11 ± 2.80 mm for superior borders (range 0.02-12.20 mm), and 2.75 ± 2.61 mm for inferior borders (range 0.22-13.58 mm). The mean intercoronoid difference was 3.57 ± 1.80 mm (range 0.91-6.11 mm).
Conclusion: This study confirmed the presumed accuracy regarding the use of fibular and mandibular cutting guides. CAD/CAM is an attractive technique which enhances efficiency and assurance during surgery and preoperative planning.

The Effectiveness and Safety of Tibial-Sided Osteotomy for Fibula Untethering in Lateral Close-Wedge High Tibial Osteotomy: A Novel Technique with Video Illustration.

: Despite its advantages, lateral close-wedge high tibial osteotomy (LCWHTO) requires proximal tibiofibular joint detachment (PTFJD) or fibular shaft osteotomy for gap closing. These fibula untethering procedures are technically demanding and not free from the risk of neurovascular injuries. Our novel fibula untethering technique, tibial-sided osteotomy (TSO) near the proximal tibiofibular joint (PTFJ), aims to reduce technical demands and the risk of injury to the peroneal nerve and popliteal neurovascular structures.

Objective: To evaluate the wound healing of recipient and donor sites following keratinized mucosa augmentation (KMA) around implants in reconstructed jaw areas and to compare these outcomes with gingival grafts in native jawbone, so as to provide clinical guidance for postoperative maintenance, and to investigate the impact of clinical experience on the evaluation of KMA postoperative healing through subgroup comparisons.
Methods: This study included patients who underwent resection of maxillofacial tumors, fibular or iliac flap reconstruction, and implant placement at Peking University Dental Hospital from October 2020 to April 2023. Three months post-implant placement, the patients were referred for KMA procedures.
Implantoplasty-Aided Prosthetic Rehabilitation for the Management of Peri-Implantitis in Maxilla Reconstructed With Free Fibula Flap: A Clinical Report.

For managing peri-implantitis, a variety of treatment modalities involving both surgical and nonsurgical methods including implantoplasty have been proposed. Implants that are placed in a free fibula flap are more prone to peri-implantitis due to the absence of firm, keratinized mucosa. Prosthetic design that offers adequate hygiene access should be designed whenever possible; otherwise, it may lead to the accumulation of plaque or biofilm that may lead to peri-implant diseases.

Purpose: This study aims to analyze microvascular reconstruction in Oral and Maxillofacial Surgery (OMFS) in Europe.
Methods: Based on previous studies, a dynamic online questionnaire was developed and subjected to internal and external evaluation. The questionnaire comprised multiple-choice, rating, and open-ended questions, addressing general and specific aspects and the impacts of the COVID-19 pandemic on microvascular reconstruction in OMFS in Europe.
