The purpose of this study was to investigate the effect of muscle impingement to healing process of the fractured bone. For the purpose, the mandibular angle area of eight rabbit were used. In the experimental group the defects were made with 1㎜, 3㎜, and 6㎜, width and 10㎜ height, then the masseter muscle flaps were impinged in the defects and sutured with internal pterygoid muscles. In the control group the defects were made only as same manner on the opposite site. The experimental animals were sacrificed at 4 weeks after surgery and the operation sites were examined under the light microscope to observe the bony repair process histopathologically. The results obtained from this study were as follows: 1. The impinged muscular tissues were disparted and released by ribroblasts and collagen cell regeneration, but not resorpted. 2. Both fractured ends were united by collagen fibers containing muscular fibers. 3. New bone formation was observed under the bony cutting ends and cortical layers. 4. There are no remarkable differencies in the histologic changes of the healing processes according to the amount of the bony defects. 5. Large quantities of bony callus formation were observed in the bony defected portions of the control group.

This is to report a case of oroantral fistula closure by palatal submucosal connective tissue pedicle flap technique. The patient, 39 year old male, had an oroantral fistula on the alveolar ridge of upper right 2nd molar area. Authors noticed the following advantages. 1. The flap was easily rotated and properly positioned without excessive tension by the two gingival bridge. 2. The wide contact surface of fresh wound gives high obstruction ability. 3. To give the patient minimal discomfort by avoidence of bare bone exposure on the palatal site. Then, the healing time can be shortened.

This is to report a case of facial asymmetry from unilateral condylar hyperplasia. 1. The patient, 29 years old female, has being suffered from facial asymmetry and masticatory disturbance for 12 years. 2. Clinical and radiographic examinations revealed hyperplasia of right mandibular condyle and elongation of condylar neck which was diagnosed as condylar hyperplasia. 3. We obtained excellent and functional results by the treatments of subcondylar ostectomy and pre-& post-operative orthodontic treatment.

This is to report of extensive nasopalatine duct cyst developed in the midline of maxilla. 1. The patient, 32 year.old female, has being suffered from the swelling and pain on the upper anterior palatal and labial gingival area, and discharge through labial fistula. 2. X-ray findings revealed well-circumscribed round radiolucent shadow on the anterior midpalate which was diagnosed as extensive nasopalatine duct cyst. 3. Histopathologic findings showed the figures of typical nasopalatine duct cyst. 4. It was treated by a combination of marsupialization, enucleation and primary closure.

The globulomaxillary cyst has been known as a fissural cyst which arised from embryonic ectodermal cells entrapped between developing facial processes. But, the origin of epithelial remnants has been a subject of confusion and controversy in the dental literature still now. This is a case report of globulomaxillary cyst which was diagnosed through the clinical, radiological, and histological examinations and review of literatures.
