Abstract:
Immediate mandibular reconstruction is always necessary for the patients receiving segmental mandibulectomy to recover the facial contour and function of occlusion. When 3D modeling is unavailable, temporary external fixator is necessary to maintain the occlusion relationship and facial contour. In this study, we introduce the clinical application of temporary external fixator for immediate mandibular reconstruction in patients receiving segmental mandibulectomy, which consists of 2 anchor claws, 2 all-round retentive arms, and 1 central locking structure. From August 2016 to September 2017, temporary external fixator was applied in 13 patients. Clinical data of gender, age, surgical procedure, duration of operation, and clinical outcomes were recorded and analyzed. Among the 13 patients, there were 4 men and nine women whose ages ranged from 21 to 64 (mean 47.7) years old. There were 9 benign and 4 malignant lesions. All lesions expended at the buccal side of mandible. 12 fibular flaps and 1 vascularized iliac bone graft were used. The mandibular defect ranged from 6 to 14 (mean 10) cm. The operation duration of surgery ranged from 5 to 10 (mean 7) hours. All flaps survived with primary healing. The occlusion and facial contour were good, without significant changes of the length of mandibular body and width of mandible before and after surgery. No functional sequelae were noted at the donor sites. From these results, the temporary external fixator is easy to operate; the surgical procedure is simple and time-saving for surgeon when 3D modeling is unavailable. The indication for temporary external fixator usage is the mandibular lesion growing outward to cheek soft tissue.
