RESUMO
BACKGROUND: The scapula free flap is becoming increasingly more utilized in head and neck reconstruction due to its natural geometry and soft tissue versatility. This study reviews the incidence rate, risk factors, and treatments of complications of scapula donor site morbidity. METHODS: A review was performed for articles published between October 1990 and November 2022 in Medline (OVID), PubMed, Web of Science, and CENTRAL. After screening, 24 articles meeting the criteria were included. RESULTS: Overall, 660 head and neck surgeries with the scapula donor bone across 24 studies were included. Twenty studies of 612 scapula free flaps reported a pooled postoperative complication rate of 10.7%, with no major complications. Seven studies of 199 scapula reconstructions showed a mean Disability of Arm, Shoulder and Hand (DASH) score of 14.39/100. CONCLUSION: With its low rate of morbidity, the scapula flap presents itself as a good alternative for patients at risk for poor healing.
RESUMO
Advanced head and neck cancers involving the mandible often require surgical removal of the diseased parts and replacement with donor bone or prosthesis to recreate the form and function of the premorbid mandible. The degree to which this reconstruction successfully replicates key geometric features of the original bone critically affects the cosmetic and functional outcomes of speaking, chewing, and breathing. With advancements in computational power, biomechanical modeling has emerged as a prevalent tool for predicting the functional outcomes of the masticatory system and evaluating the effectiveness of reconstruction procedures in patients undergoing mandibular reconstruction surgery. These models offer cost-effective and patient-specific treatment tailored to the needs of individuals. To underscore the significance of biomechanical modeling, we conducted a review of 66 studies that utilized computational models in the biomechanical analysis of mandibular reconstruction surgery. The majority of these studies employed finite element method (FEM) in their approach; therefore, a detailed investigation of FEM has also been provided. Additionally, we categorized these studies based on the main components analyzed, including bone flaps, plates/screws, and prostheses, as well as their design and material composition.
