A progressive hemifacial atrophy is characterized by progressive atrophy of subcutaneous fat and rarely muscle and bone. Its contour follows the underlying muscle. Unilateral involvement is common. The treatment goal has been focused on the augmentation of the soft tissue. Many materials such as implants, collagen, fat graft, fat injection, dermal fat graft, filler and vascualized autogenous graft have been used. Although these materials have been used, the best treatment hasn't been achived. In severe cases underlying soft tissue, muscle and bone may be atrophied and massive soft tissue graft, implant and orthognathic surgery must be used. The author used the dermal-fat tissue for the pupose of soft tissue augmentation. We can get the massive soft tissue by the dermolipectomy procedure through the mini-abdominoplsty. The facial augmentation was done by augmentation of the dermal-fat tissue. The progressive hemifacial atrophy is hard to treat by only one procedure and many modalites must be considered.

Although an ameloblastoma is a benign tumor histologically, it may act malignantly. It has locally destructive and recurrent tendencies. Many different strategies have been attempted in order to cure an ameloblastoma including curettage, enucleation, marsupialization, and resection with a safty margin. Curettage, enucleation, and marrsupialization can be classified into a conservative treatment and resection with a safty margin can be classified into a radical treatment. Radical treatment has better results than the conservative treatment. Thus, more radically conservative treatment methods are needed in order to improve the treatment results. The cryosurgery can be applied an ameloblastoam. In particular, with regards to the solid and intramural type, the application of the cryosurgery has its advantages over the conservative treatment. After resection of the diseased area we don't need to discard the diseased segment. Instead, by placing the segment in liguid nitrogen, the diseased segment can use the autogenous tray for packing several bone materials.

Oral leukoplakia is the most common premalignant lesion and malignant transformation has been reported from verrucal lekoplakia. Homogenous, benign leukoplakia develops into a line of squamous cell carcinoma such as verrrucous carcinoma, papillary squamous cell carcinoma and invasive squamous cell carcinoma. Early diagnosis and intervention of premalignant leukoplakia is up-most important to prevent transformation into a oral squamous cell carcinoma. Any change in surface, size and color warrants repeated biopsy. If verrucous carcinoma is evidently derived from the previous leukoplakia, wide surgical excision and periodic follow up is needed. Surgically removed lesion of leukoplakia has the tendency to recur. Follow-up is very important to patient and clinician. Although many therapies have been reported to oral leukoplakia and verrucal carcinoma, accepted treatment principle is not exist so far. But surgical removal is recommended as the treatment of choice.
