surgery. The two part design resists highly to the fracture or deformation during implantation and removal. The long span head allows the patient to easily attach intermaxillary elastics, so that the patient can apply intermaxillary elastics for traction easily. Through this article, we tried to show the possibility of this appliance as a good adjunct for the IMF screw.]]>

Soft tissue defects resulting from head and neck tumor resection seriously impact the physical appearance and psychological well-being of patients. The complex curvature of the human head and neck poses a formidable challenge for maxillofacial surgeons to achieve precise aesthetic and functional restoration after surgery. To this end, a normal head and neck volunteer was selected as the subject of investigation. Employing Gaussian curvature analysis, combined with mechanical constraints and principal curvature analysis methods of soft tissue clinical treatment, a precise developable/non-developable area partition map of the head and neck surface was obtained, and a non-developable surface was constructed. Subsequently, a digital design method was proposed for the repair of head and neck soft tissue defects, and an in vitro simulated surgery experiment was conducted. Clinical verification was performed on a patient with tonsil tumor, and the results demonstrated that digital technology-designed flaps improved the accuracy and aesthetic outcome of head and neck soft tissue defect repair surgery. This study validates the feasibility of digital precision repair technology for soft tissue defects after head and neck tumor resection, which effectively assists surgeons in achieving precise flap transplantation reconstruction and improves patients' postoperative satisfaction.

With rapid advancement in techniques of correcting multiple facial anomalies, surgical planning has become more sophisticated, and knowledge of the exact relationship between various areas of the head and face is now indispensible. The importance of capturing the face in proportions has been emphasized by many surgeons. The neoclassical canons are known to modern plastic surgeons, but their usage in surgical planning has been limited to the role of working guides. They are useful, however, in serving as standards. The authors measured 800 normal young Korean females, ranged from 19 to 26 in age, and 21 beauty contestants in Korea, ranged from 20 to 27 in age. Seven vertical and seven horizontal linear measurements were taken from each subject by one examiner. These measurements of normal face and attractive face are compared with each other, and followed by comparison with neoclassical canons. Attractive face of Korean female comprises shorter lower face, especially from stomion to menton, narrower bigonial distance, and longer midface than normal face. It also has wide palpebral fissure and narrow intercanthal distance. Korean female face comprises shorter and narrower lower face than neoclassical canons. We think that it is valuable to take into consideration of this modern concept of beauty when making a preoperative plan for facial plastic surgery.
