RESUMO
By using distraction osteogenesis technique, 3 cases of mandibular hypoplasia were treated by home-made and German-made jaw distractors: including one patient suffered from bilateral ankylosis of temporo-mandibular joint and 2 patients from deficiency of mandible. The duration of distraction osteogenesis was one month. The bone distractor was removed 3 months after operation. Satisfactory results were obtained in all 3 cases. Distraction osteogenesis can successfully be used in mandibular functional reconstruction and has much more advantages than traditional technique.

<p><b>OBJECTIVE</b>To use virtual endoscopy to obtain detailed three-dimensional images of bone, soft tissue and paranasal sinus damage as well as images of adjacent unaffected areas for optimum surgical planning.</p><p><b>METHODS</b>A spiral CT scanner was used to examine 46 cases of facial bone fractures, maxillary cysts, obstructive sleep apnea syndrome (OSAS) and maxillary bone tumours. Data were input into a navigator workstation to create images similar to those displayed by a fiberoptic endoscope. Various 3-D images were obtained when probe sites were changed.</p><p><b>RESULTS</b>Virtual endoscopy can clearly display the anatomic structure of the paranasal sinuses, nasopharyngeal cavity and upper respiratory tract, revealing damage to the sinus wall caused by a bone tumor or fracture. In addition, the technique can be used to indicate volume changes of the upper respiratory tract in OSAS patients. These results were similar to those obtained through actual operations.</p><p><b>CONCLUSIONS</b>Virtual endoscopy is a new method which produces very clear images. It is reliable to provide detailed information for optimal operative planning.</p>

To treat large facial defect (more than 6 cm x 4 cm in diameter) or a wound with bone exposure to atmosphere by less-traumatic, easier-healing reconstruction method, a pedicle flap including facial, neck, posterior auricle and occipital skin flap was designed and transferred, one by one, to repair facial defect as well as other flap donor sites, but occipital skin flap was only used to cover posterior auricle area. After 2-3 years follow-up, well-healed skin flaps with good color, elasticity and sensation were observed in all 16 patients. It is concluded that this method is effective and practical.
