The granular cell tumor, formerly known as granular cell myoblastoma, is an uncommon neoplasm of unknown etiology. The first case of granular cell tumor was probably reported by Muller in 1839. Three main histogenic theories have been proposed : 1) neurogenic, 2) myogenic, and 3) histocytic. A sterm cell theory of origin from undifferentiated mesenchymal cells unifies the three hypothese. The lesion occurs over a wide age range, with a peak in the 4th to 6th decades. There is a 2:1 fermale prevalence and a predilection for blacks. Granular cell tumor occurs anywhere except in bone, with the skin and tongue the most common sites. About 50% of granular cell tumors occur in the head and neck, with 60% of them in the tongue. Treatment is surgically excised, and recurrence is not expected. Spontaneous regression has been noted but is apparently a rare event.

Fibrous dysplasia is a benign pathologic condition of bone which medullary bone is replaced and disturbed by poorly organized, structually unsound fibro-osseous tissue. When facial bones are involved, considerable esthetic deformity may result. The term monostotic fibrous dysplasia has been applied when one bone is involved : when more than one bone is affected, the term polyostotic used. The polyostotic form may be accomplished by pigmented skin lesion (Jaffe type), or by pigmented skin lesions with endocrine disturbance (Albright syndrome). No general agreement exists on the cause of fibrous dysplasia. A few authors have suggested that fibrous dysplasia as a result of trauma. It occurs predominantly in infant, adolescent females and runs a variable clinical coures. When several bones are involved, it tends to be unilateral. Involvements of alveolar bone may produce displacement of teeth with malocclusion, or loss of teeth, or both. Now, we will present a case of fibrous dysplasia on the left facial region treated by conservative contouring surgery.

Aneurysmal bone cyst is a benign lesion of bone consisting of a septated, cystic cavity filled with non-endothelium-lined, blood-filled spaces. As it grows, expanding and destroying the affected part of the bone by direct compression, the lesion characteristically produces a prominent bulging of the affected bone, which eventually erodes the overlying cortex. Patients rarely complain of pain unless the cyst affects adjacent nerves or its expasion is great enough to impinge on the surrounding joints and soft tissue. Teeth adjacent to the cyst may be displaced, but usually remain vital. Development of the lesion in the craniofacial region is rare, and the mandible is more often affected than the maxilla. Complete surgical excision is used to treat aneurysmal bone cyst, with either curettage or composite resection. This is a case report of 49 years old female with aneurysmal bone cyst treated with surgical excision & DFDB graft.

Despite the current accomplishments with the repair of cleft lips, the surgical management of the nasal deformity remains a functional and aesthetic dilemma for patients, their families, and reconstructive surgeons. Recent improvements in the understanding and technical execution of te primary cleft lip repair have significantly reduced secondary sequelae and the consequent need for secondary surgical correction. But, secondary surgical corrections are necessary according to numerous factors. Such factors include the secondary surgical corrections are necessary according to numerous factors. Such factors include the severity of the initial deformity, the surgical plan, precision of execution of the primary repair, and success of the postoperative management. We preformed the secondary correction of cleft lip and palate in 11 patients via various methods. In conclusion, primary repair of cleft lip and palate patients is the most important to prevent the secondary deformities, and most of cleft lip and palate with secondary deformities must be treated with combined cheiloplasty and rhinoplasty.

Bilateral cleft lip reconstruction can be performed in one-or two-stages. The choice depends on the surgeon's proficiency and experience. However the type and severity of the cleft must be considered. Complete or incomplete symmetric, bilateral clefts in which the premaxilla is within the alveolar arch or slightly protruded can be successfully treated with simultaneous lip reconstruction on both sides. There are some advantages that one-stage lip reconstruction facilitates creation of a symmetric and balanced lip, retraction of protruding premaxilla and the parent's psychologic satisfaction. However, there are some disadvantages such as micrognathia of the upper jaw by severe scar formation and poor adaptation of flap margins by severe tension. The surgeon must be able to judge and exploit the advantages offered by one-stage approach. We present the case report of one-stage reconstruction of primary bilateral cleft lip with literature reviews.
