Fibrous dysplasia is a benign pathologic condition of bone and causes facial deformities as well as functional problems. We have managed 32 craniofacial fibrous dysplasia form March 1989 to December 1993. The most common age distribution of surgery was second decade(34%) and third decade(53%). In our patients, the desease process usually begins in childhood and progresses throughout puberty and adolescence. Treatment was aimed at preventing and correcting functional problems and achieving normal facial aesthetics. The reconstruction with other combined surgery, i.e., mandibular and maxillary osteotomies, reduction malar plasty, malar augmentation and orbit, nasal reconstruction with bone graft. Postoperative results were satisfactory in most cases. In some patients, repeated contouring(16%) surgery might produce less morbidity than a single massive resection. In evaluating the extent of the lesion, computerized tomography prooved to be a good diagnostic tool. Aethetically and functionally satisfactory surgical results were achieved by bone shaving in combination with reconstructive surgery.

백롱민,박재현,김진환,백세민,오갑성,정연철 大韓成形外科學會 1993 Archives of Plastic Surgery Vol.20 No.5

The shape and contour of the upper third of the face is provided basically by the frontal bone. A relatively thin soft tissue coverage, which consists of the skin and frontalis muscle, readily shows subtle changes on the underlying frontal bone. The forehead represents the fortune of one's youth from the viewpoint of physignomy, and a broad forehead with minimal supraorbital bossing and round curvature is preferrd in the Orient. The forehead with a deficient, flat contour or asymmetry could be indicated for augmentation. The exact site and amount of augmentation are dicided preoperatively using clinical assessment, medical photographs, and cephalometric analysis. Hydroxyapatite(Pyrost), because of its nonresorbability, seems to have advantages over other alloplastic materials for forehead augmentation. From March 1989 to February 1992 forehead augmentation has been performed in 60 patients. Through a coronal incision, the dissection was carried over the periosteum to the supraorbital ridge and the lateral orbital rim. The subperiosteal pocket was made through a small incision, and was packed with Pyrost. When indicated, facial rhytidectomy, or reduction malar plasty was performed simultaneously. The result had been satisfactory and long lasting. There had been no implant shifting, infection, or bony erosion when examed from 1 year to 4 years after surgery.

유리피판술을 이용한 진행성 반안면 위축증(Romberg's Desease)의 치험

백롱민,정두성,백세민 大韓成形外科學會 1999 Archives of Plastic Surgery Vol.26 No.5

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 ½ 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.

하악각축소술시 절제된 골의 간치이식을 이용한 턱끝증대술

이태일,백룡민,오갑성,백세민 大韓成形外科學會 1997 Archives of Plastic Surgery Vol.24 No.5

The square face or the box face appearance is quite common in orientals as well as occidentals and consists of flaring at the mandible angle areas with exaggerated posterior inferior projection of the mandibular angle in combination with a small and weak chin, resulting in widened bigonial distance and shortened lower third of face. Such patients complain of unbalanced and masculine appearance and may regard themselves as unaesthetic. To correct these deformities simultaneously, the mandible angles were resected (angled osteotamy) and the bone fragment from these ostectomized mandibular angles were used to augment the chin as an autogenous interpositional bone graft. At the Institute of Plastic and Reconstruction Craniofacial Surgery(IPRCS), Ice University Collage of Medicine, twenty eight cases were successfully operated in this manner during a six-year period from June 1989 to May 1995. Patient's satisfaction was high and improved esthetics were noted in all patients with minimal complications. The advantages are: l. Simultaneous correction of prominent mandible angle and augmentation of the deficient chin area. 2. Provides vertical elongation of the chin and lower face, which gives visual compensation for agittal weakness of the lower face. 3. Improves upper and lower facial balance. 4. Another donor site for bone is not necessary, thus avoiding unnecessary donor site morbidity. 5. Homogenous autologous bone is used thus reducing the chance of resorption. 6. Minimal chance of infection.

허찬영,백롱민,백세민 大韓成形外科學會 1999 Archives of Plastic Surgery Vol.26 No.4

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.
