Patients with a poor or total absence of levator function require correction of their ptosis by a sling procedure. The aim of the procedure is to utilize the action of the frontalis muscle to mechanically raise a droopy eyelid Frontalis suspension procedure using a temporalis fascia or Tutoplast Dura was performed on 36 ptotic eyelids of 23 patients(age range 2-37 years) with a poor or absent levator function. The author used a surgical technique based on a modified Fox`s method. Satisfactory results were achieved in 42 lids according to the criteria of Jordan after an average follow-up of 23 months. No serious complication was seen immediately postoperative and during the follow-up period. Temporalis fascia and Tutoplast Dura appear to be effective and safe alternative sling materials for frontalis suspension surgery.

Romberg's disease is an uncommon condition manifested by progressive hemifacial atrophy of the skin, soft tissue and bone. Facial asymmetry with soft tissue deficiency in Romberg's disease causes a significant disability affecting the social life and can bring about many psychological problems. The aim of surgical treatment is cosmetic amelioration of the defect. Several conventional reconstructive procedures have been used for correcting facial asymmetry. They include fat injections, dermal fat grafts, silicone injections, cartilage and bone grafts, pedicled flaps and free flaps. We report our experience with 6 patients involving 6 free flaps with a minimun of 1 year follow-up who were treated from October 1989 to March 1998. All patients were classified as having moderate to severe atrophy. The average age of disease onset was 4.5 years. The average duration of atrophy was 5.2 years. No patient was operated on with a quiescent interval of less than 1 year. The average age at operation was 14.1 years, ranging from 10 to 24 years. Follow-up ranged from 1 to 9 years. Reconstruction was performed using 2 groin dermofat free flaps and 4 latissimus dorsi muscular free flaps. To achieve the finest symmetrical and aesthetic results, several ancillary procedures were performed in 4 patients. These procedures included Le-Fore 1 1/2 leveling osteotomy, sagittal split ramus osteotomy, reduction malarplasty and angleplasty, rib and calvarial bone graft, correction of alopecia and additional dermofat graft. All patients were satisfied with the results. We believe that free flap is one of the best choices for contoured restoration of facial asymmetry in Romberg's disease.

The first successful bone transplantation carried out in 1688 by Van Meek'ren, a Dutch surgeon. The ideal bone substitute should be biocompatible, osteoinductive or at least osteoconductive, available in unlimited quantity, low cost and have satisfactory mechanical properties. To accomplish these goals, autografts are still preferred material. However, bone harvesting procedures have been focused to solve the following problems; necessity of a second surgical site, morbidity and potential deformity of the donor site, an increased operative time, donor availability limitations, and resorption of autogenic bone grafts.Ten adult white New Zealand rabbits, three, 10 mm in diameter, full layer skull defects were made in the frontoparietal bone. Two bone defects were filled with hydroxyapatite and powdered eggshell, the other defect was not filled(control). All animals were sacrified at 10 weeks, the specimens were examined macroscopically to test for graft mobility. The graft with surrounding bone was then harvested and studied by histology. The results were as follows: 1. Control: Bone regeneration occurred nearly complete. 2. Hydroxyapatite: Macroscopically - No encapsulation. Despite a gross delineation between implant and bone, imlant was firmly united to bone. Histology - Bony trabeculae surrounded by proliferated connective tissue are observed in the defect site and implant. Osteoblastic rimming is noted along the bone fragments 3. Powdered eggshell:Macroscopically - Grafted site was encapsulated by proliferated connective tissue and palpable softer than the surrounding bone. Histology - The presence of eggshell particles encapsulated by fibrous connective tissue. Partial bone regeneration from the defect margin was noticed, but the bone healing was never complete. In conclusion, the use of safe and inexpensive material is recommended for filling limited bone defects in non-weight bearing areas. The use of powdered eggshell for bone substitute may also be considered, after further studies, to access its long term stability, porosity and biocompatibility.

We reviewed surgical specimens from 11 patients with diffuse neurofibroma to define the specific clinicopathologic characteristics. Ten cases were cutaneous neurofibromas and one case was an uncommon gastrointestinal neurofibroma involving the rectum. The most frequent sites of involvement were the head and neck, especially the eyelids and the periorbital areas. They usually presented as a plaque-like elevation of the skin. They primarily occured in children and young adults and positive family histories of von Recklinghausen's neurofibromatosis were obtained in 45.4%. Pathologically, the involved skin & rectum were diffusely thickened by an infiltrative growing mass, showing proliferation of short fusiform cells in the uniform matrix of fine fibrillary collagen. The characteristic prominence of Wagner-Meissner bodies (45.4%) suggests they could be associated with pathogenesis of diffuse neurofibroma. On the basis of these findings, we could confirm diffuse neurofibroma to be a distinct form of neurofibroma.
