Patients with facial paralysis, in whom nerve damage is irreparable or in whom the innervation of the paralyzed musculature cannot be restored by nerve suture, grafting, or cross-face nerve transplantation, should be offered some form of reconstructive static and dynamic aid. Temporalis muscle-fascia unit used as a circumorbital sling and motor unit is a dynamic controlled reconstructive procedure, but it has several disadvantages such as wide surgical exposure, bulky-looking at lateral canthal area, insufficient voluntary control. This is a case report of facial palsy of posttraumatic lagophthalmos of 41-year-old male, which was corrected by temporalis muscle-tendon transfer with plantaris tendon transplantation.

Tumors arising from nerve tissue are uncommon in the oral maxillofacial regions. Neurofibroma, a benign neurogenic tumor, can occur as circumscribed solitary or multiple lesions. A solitary neurofibroma is seldom undergo sarcomatous transformation, but fibromatosis is common. Therefore, it is important that we observe the oral and radiographic changes to help minimize the tremendous potential of the disease for facial disfigurement and altered function. The tumors were excised and there are no evidence of recurrence. The patients are satisfied with function and esthetic aspects.

This is a case report and review of literature that deal with a surgical correction of mandibular deficiency. Patient, 38 years old male, had visited to treat mandibular deficiency. On the basis of clinical and radiographic examination, he was diagnosed as a micrognathia. Surgical method. 1. Intraoral Bilateral sagittal split osteotomy 2. Augmentation of genioplasty - double step. Patient was satisfied with final esthetics by gnathosurgery.

The aim of this article was to examine the usefulness of costochondral graft in the temporomandibular joint reconstruction. We performed costochondral grafting in the mandibular reconstruction including condyle replacement in 3 patients, which 2 of ankylosed cases and 1 destructed case. In one case, unexpected fracture of costochondral junction has developed at post-operative 2 months, but, normal mouth opening and facial appearance have been acheived by continuing exercise. These patients showed maximum mouth opening of 35-40 mm and no restriction of lateral side movement. They have been improved esthetics and function. We proposed that the costochondral graft is one of the useful method for functional reconstruction of defected mandibular condyle.

Kole's Anterior segmental osteotomy of the mandible is commonly used to close an anterior open bite, to depress an elevated anterior dentoalveolar segment, or to retrude or advance a dentoalveolar segment. The procedure is often combined with an anterior maxillary segmental osteotomy to correct bimaxillary protrusion. We report 53-year-old woman who the extruded state of mandibular anterior alveolar segment was corrected using an mandibular anterior alveolar segmental osteotomy and dental implantation of the anterior maxilla. We planned to remove the old prosthesis, and then perform an anterior mandibular segmental osteotomy and implant restoration of the anterior maxilla. We suggest that anterior segmental osteotomy is very useful for rehabilitating edentulous patients with malaligned alveolar segment.

Improvement of orthognathic surgical techniques make it possible to design esthetic surgical correction for total esthetic face. In order to find the esthetic line which guide esthetic surgical correction in patients of orthognathic surgery, cephalometric soft tissue analysis of esthetic faces were performed. In esthetic Korean young adults, 25 males and 25 females who were within 1 S.D. of E-line, ANB, P/A facial height ratio, were analyzed in natural position keeping their face eye level. 1. Sn position is constant in males and females. The Sn-N'-N' Vertical plane angle is $5.3^{\circ}$ in both sexes. Sn is positioned in front of 5 mm in female 7 mm in male from the N' vertical plane. 2. The Sn-Ls line make constant angle to horizontal plane with $72.5^{\circ}$ in both sexes, which is called "upper esthetic line". The Ls-Pg' line makes constant angle to $72.4^{\circ}$ (range $72.2^{\circ}$ in female to $72.6^{\circ}$ in male), which is called "lower esthetic line". 3. When inter-esthetic line angle (the Sn-Ls line to Ls-Pg' line) has $144.9^{\circ}$, lower third face has esthetic upper and lower lip. 4. In treatment planning, Sn is first corrected in proper position, and then upper and lower esthetic line are established with the angle of 144.9. The maxilla is moved to tangent Ls to the upper esthetic line, and mandible is moved to tangent Li and Pg' to the lower esthetic line, according to the "y"-shaped esthetic lines, then lower third face showes esthetics.

As carotid-cavernous fistula is the major complication that can be occurred uncommonly after maxillofacial injuries, it is abnormal arteriovenous communication between cavernous sinus and internal carotid artery. Such an arteriovenous communication is most often the result of injuries, but need not be associated with bony fracture. It usually begins soon after an injury, but it may be delayed for as long as several months. It begins undramatically with eye pain, headache and slow protrusion of eye ball. A bruit may be heard above the eye with stethoscope. Close examination will reveal dilatation of superficial veins of the eyelid and forehead and periorbital edema. There will be complete or partial ophthalmoplesia of the affected eye. Compression of the common carotid artery on the ipsilateral side will reduce or obliterate the bruit. The lesion in the cavernous sinus is them demonstrable by angiography.

Fibrous dysplasia is a benign pathologic condition of bone in which fibrous tissue gradually expands and replaces normal bone into fibro-osseous lesion. It is a primary developmental abnormality of bone-forming mesenchyme in origin. This study shows clinical history, radiological and histopathological feature of fibrous dysplasia with the intention of establishing correct diagnosis, treatment plan and evaluation of prognosis. This paper reviews and summarizes the materials from 57 fibrous dysplasias submitted to the Department of Oral and Maxillofacial Surgery in College of Dentistry, Seoul National University. Conclusions obtained were as following : 1. Fibrous dysplasia developed mainly in teenagers and shows female predeliction. 2. Fibrous dysplasia developed much on the maxilla 3. Monostotic fibrous dysplasia was most popular form. 4. Main symptom of fibrous dysplasia was painless swelling. 5. Radiological feature of fibrous dysplasia was ground-glass appearance, 6. Histopathological feature of fibrous dysplasia was irregular immature bony trabeculae(woven bone). 7. Treatment of fibrous dysplasia was mainly conservative contouring surgery.

Recently, the anterolateral thigh(ALT) flap, based on the septocutaneous vessels or musculocutaneous perforators from the descending branch of the lateral circumflex femoral artery has gained popularity in head and neck soft-tissue reconstruction. It has some advantages in free-flap surgery with respect to the radial forearm free flap, such as low donor site morbidity, availability of different tissues with large amounts of skin, adaptability as a sensate or flow-through flap (with the possibility of harvesting a long pedicle with a suitable vessel diameter). Moreover, the thickness of the flap is adjustable until the subdermal fat level, allowing it to be used as a thin or ultrathin flap. This clinical cases are ALT free flap reconstructions without functional impairment of the donor limbs (transitory and permanent) based on anastomosis with superficial temporal arteries and veins in patient of huge resection defect on face, lip and tongue.
