Clinical Research Of Reconstruction Of The Defects Of Bone And Soft Tissue Resulted From Oral And Maxillofacial Tumors

Objective:To explore the values of the different tissue flap in reconstruction of the defects of bone and soft tissue resulted from oral and maxillofacial tumors for the aim of individual reconstruction in shape and function.Methods:From January2009to January2012, total131patients operated in our department resulted from craniomaxillofacial tumors reconstructed with different tissue flap were analyzed retrospectively. This tissue flaps were included free fibular myocutaneous flap (19cases), free iliac myocutaneous flap (20cases), free iliac crest and rib graft repair of a total of three cases; pectoralis myocutaneous flap (26cases), latissimus dorsi flap(8cases), forearm flap (18cases), anterolateral thigh myocutaneous flap (21cases), promote the lip and cheek adjacent soft tissue flap, cross lip flap16cases. Their age, gender, disease, defect size,tissue flap survival rate and effect of postoperative were analyzed.Results:In Our department of the past three years, total success rate in131tissue flaps was95.41%. In Soft tissue flaps, the anterolateral thigh flap was the most commonly used (23.43%), the second was forearm flap (21.87%).In reconstruction of bone defect, the iliac myocutaneous flap was most commonly used (29.85%). Pectoralis major muscle flap and latissimus dorsi flap were used in reconstructing of a large area and composite defects. Free fibula myocutaneous were used in reconstruction of total defect of mandibular and defect crossed midline. Free iliac myocutaneous flap were used in reconstruction of half side defect of mandibular mainly.Conclusions:The tissue flap transplantation was the main method in reconstruction of the defect of oral and maxillofacial area resulted from tumor resection. It had important significance on recovery of appearance and functions of patient and improving the survival rate and life quality. Forearm flap was preferred to repair tongue, cheek, palate, and other soft tissue defects; pectoralis major myocutaneous flap and latissimus dorsi myocutaneous flap for repairing larger defects; fibular myocutaneous iliac myocutaneous flap for the mandibular defects most commonly. The other tissue flap should be selected according to different indications. Individual reconstruction in oral and maxillofacial defect has great significance for the postoperative appearance and function.
