“…3) The skin of the ap should be used primarily to reconstruct craniomaxillofacial defects, the pectoralis major to ll the remaining cavity, and the subcutaneous tissue to repair oral mucosal tissue defects. Complete myofascialization of the myofascial tissue occurs 15-20 days after repair of oral mucosal defects 22 . 4) The vascular pedicle should ensure proper tightness.…”

“…The proximal end of the ap should be located not only on the medial aspect of the papilla but also on the lower line of the junction between the upper and lower quadrants. The distance from this point to the midpoint of the inferior margin of the clavicle should be slightly greater than that from the inferior margin of the maxillofacial defect area to the midpoint of the clavicle, and its shape is required to be comparable to that of the defective tissue 22,23 . Based on the above considerations, the characteristics of the tissue defect repair include: tissue excision for oral tongue oor defects mainly from the medial and inferior quadrants, mandibular buccal penetrating defects from the medial and lateral inferior regions, maxillary palatal defects from the inferior quadrant and anterior rectus abdominis sheath, and large craniomaxillofacial tissue defects from the medial inferior, lateral inferior, and anterior rectus abdominis sheath.…”

Purpose: The purpose of this study was to investigate the quality of life and survival of pectoralis major myocutaneous flap (PMMF) in soft tissue defect after resection of oral and maxillofacial malignancies. Materials and Methods: A retrospective analysis was performed on 56 patients who underwent oral and maxillofacial malignancy removal with tissue defect from 1st January 2015 to 1st January 2018. The Chinese version of the Functional Assessment of Cancer Therapy-Head & Neck scale and the Kaplan-Meier method were used to assess the quality of life and survival rate, respectively. Results: The grafted PMMFs had a satisfactory survival condition in all 56 cases. Compared with the preoperative period, the questionnaire at 6 months postoperatively showed a remarkable improvement in patients’ physical well-being, social/family well-being, emotional well-being, functional well-being, additional head and neck concerns as well as total score (P < 0.05). Moreover, the 3-year and 5-year survival rates calculated by Kaplan-Meier method were 48.2% and 42.1%, respectively. Conclusions: Within the restrictions of this study, PMMF is a promising method for salvage reconstruction of tissue defects after oral-maxillofacial malignancy resection due to it’s constant anatomical structure, abundant tissue volume, high survival rate and effective improvement of patients’ quality of life.

The aim of this study was to establish finite element models of free fibular flap reconstruction of different types of mandibular defects. The finite models was created from CT image. The finite element method was used to carry out biological analysis. Comparative analysis of the stress distribution characteristics and the displacement changes in mandible were carried out. From the stress distribution nephogram, it could be concluded that the stress was mainly concentrated in the bilateral condylar neck, the anterior and posterior edges of the mandibular ramus, and the joint between the posterior end of the fibula and the mandible. The more mandibular defects that were present, the greater the corresponding stress on the contralateral condyle. Displacement nephogram: the inward displacement of the condyle on the affected side of a type B defect was more obvious than that of the normal mandible, and the most obvious in the X-axis direction, with a displacement of 1.61 mm; the BSS defect crossed the midline, and the bilateral condyles shifted inward causing posterior displacement; the displacement results of RBS and CRBS defects showed whether the condyle was involved in the bone defect, and the displacement changes after reconstruction were not significantly different. After mandibular reconstruction, the loss of attachment muscles can cause postoperative condylar displacement, resulting in postoperative occlusal disorder, opening deviation and other complications.
