Description

In the field of oral surgery, mandibular resection is often required in patients with various mandibular lesions. Though immediate reconstruction after mandibular resection is desirable to maintain function, mandibular resection should be approached not only in terms of function but also esthetics, i.e., reproduction of facial features. Reconstruction has been performed using autologous bone and various medical artificial materials, but there are no established methods for facial reconstruction.<BR>Since 1987, we have produced 3-dimensional mandibular models based on 2-dimensional CT images taken before surgery for patients in whom marked deformation is expected after mandibular resection. Casting titanium plates are designed using this 3-dimensional model, casted, and used for mandibular reconstruction.<BR>In this study, we report this method and the clinical course and problems of 6 patients treated by this method between 1987 and 1989.<BR>Esthetically, good results were generally obtained after segmental resection. In patients in whom a large amount of soft tissue was resected, or in whom the plate width was short, depression in the skin developed. Concerning mastication function, this method accurately restored the remaining bone and allowed good occlusion on the normal side. These may be important conditions for functional recovery. MKG showed a mandibular movement pattern in which the affected side follows the normal side in patients with extensive invasion to the masseter muscle. This suggested the need for the early initiation of movement practice.
