ABSTRACT

Facial beauty depends on the form, proportion and position of its various units. The chin is the most prominent element of the lower third of the face, both in the frontal view and in profile. Whether it is advisable to perform rhinoplasty first, followed by genioplasty, or the reverse depends on the type and severity of the deformities of the nose and chin. The selection of material is a matter of the plastic surgeon's preference. Fat is an ideal tissue filler substance because it is living tissue and from the patient's own body. So it is nonallergenic. The procedure can be performed alone as a chin augmentation with fat grafting or in combination with rhinoplasty or other facial surgery. The technique requires minimally traumatic fat harvesting, fat preparation, and multi-level facial infiltration. Remnant fat in the initial procedure is frozen and stored at -18C and can be used successfully for minor touch-up procedures. We have performed a review of chin surgery, the multiple aesthetic analyses available and the advantages and disadvantages of the various materials. Autologous fat transfer to the chin is safe, cost effective, and can produce long term aesthetic improvement. Although there are many synthetic fillers available, autologous fat is perhaps the best option for genioplasty. This simple, fast procedure is a very good alternative for patients with some form of microgenia or when patients and surgeons are not likely to use alloplastic implants.

ABSTRACT

PURPOSE: For facial reconstruction, skin color match is crucial to achieve great aesthetic result. Forehead flap and full thickness skin graft have been used for many years to reconstruct facial defect. Their results are aesthetically valuable with remarkable resemblance and harmony of the skin color between donor and recipient sites. The purpose of this study is to evaluate and compare the aesthetic outcome of the two methods as the analysis of skin color match. METHODS: From January 1995 to December 2005, ten forehead flaps and ten full thickness skin grafts were performed. The reconstructed areas of forehead flaps were five noses and five eyelids. Recipient sites of full thickness skin grafts were seven eyelids, two noses and one forehead. In order to obtain the objective validity, the skin color of flap(or graft) and the recipient sites were measured by chromameter. The skin colors were quantified according to a three-dimensional coordinate system used in chromameter, L*(brightness), a*(redness), and b*(yellowness). RESULTS: There was no significant color difference between forehead flap site and adjacent skin in all color values. On the other hand, the L* and b* values of graft sites were significantly lower than those of the adjacent skins. The a* values of graft sites were higher than those of the adjacent skins. CONCLUSION: This study reveals that skin color match of forehead flap is greater than that of full thickness skin graft. As forehead flap has adequate volume and great color match, it can be useful to reconstruct deep facial defect such as nasal defect. On the other hand, full thickness skin graft can be used for superficial defect like partial eyelid defect.

ABSTRACT

Schwannomas or neurilemmomas are the most often found as solitary, slow-growing, asymptomatic, well-encapsulated, firm yet transversely mobile benign mass in head and neck region. Most of Schwannomas appear in the cranial nerve, especially vestibular nerve, but must always be considered to be able to appear in any parts where the nerve tissues are distributed. Sometimes, inaccurate preoperative clinical diagnosis leads to accidentally resecting the affected nerve and produces permanent neurological deficits. We experienced a extremely rare schwannoma being confused with lipoma in upper left postauricular sulcus. After simple mass excision without considering possibility of schwannoma, the patient complained of dull sensation and pinprick pain in the superior part of the ipsilateral postauricular area. When clinical symptom and physical examinations are insufficient to distinguish schwannoma from other benign soft masses, and the mass along the critical nerve pathway can possibly be originated from the designated nerves, we would like to recommend radiologic examinations such as ultrasonography and/or MRI for correct diagnosis prior to operation. Moreover, when it is adjacent the neurovascular structures, meticulous microscopic surgery must always be performed so as not to impair the important structures.

ABSTRACT

PURPOSE: Full-thickness skin grafts are usually used in facial reconstruction, but on occasion, split-thickness skin graft is also used from the scalp due to the limitation of donor site. However, there were complications, such as alopecia, folliculitis and blood loss. In addition, it can not be used in patients with baldness. Under the circumstances, we used medial arm skin as split-thickness skin graft donor site in lieu of scalp. We investigated the efficacy of the medial arm skin as a donor site of facial skin graft in comparison with scalp. METHODS: From 2000 to 2005, the split-thicknesss skin grafts were performed using the medial arm skin in 10 patients and the scalp in 10 patients. We inspected the skin color match, texture match by the visual analogue scale. Scar contracture was estimated by the Visitrak grade(R)(Smith & Nephew). The statistical analysis was performed by SPSS 12.0. RESULTS: There was a more satisfaction in color match, texture, and scar contracture in medial arm skin than in scalp. CONCLUSION: According to these results, medial arm skin may be used efficiently as an alternative donor site of scalp in the facial reconstruction.

ABSTRACT

PURPOSE: Purpura fulminans is a rare but rapidly progressive, serious, often life-threatening disorder in childhood, which is complicated with septic shock or disseminated intravascular coagulopathy during acute infection. It occurs first as acute-onset petechial rash, and spreads rapidly into full thickness skin and soft tissue necrosis. In the past, it had high mortality rate, up to 80%, but recently, survival rate has increased due to early diagnosis, and rapid advancement of critical care and antibiotics. From our experiences of PF management, we would like to review the pathophysiology and suggest the surgical treatment guideline about meningococcal induced purpura fulminans. METHODS: Two cases of purpura fulminans over the last 3 years were reviewed retrospectively about reconstructive management. After they were treated resuscitative management initially by the critical intensive care, reconstructive surgery was performed by plastic surgeon as soon as the patients were vitally and mentally stable. RESULTS: There were 6 procedures in case 1, and 3 procedures in case 2. The mean delayed period from admission with sepsis to the first surgical debridement was 24 days and 42 days, respectively. Total hospitalization period was 103 days and 69 days, respectively. All of them were treated with debridement and split thickness skin graft, but delayed debridement was superior to early one in the point of preserving much more tissues. CONCLUSION: From our experience, we suggest that conservative therapy to the wounds appears to be the best tool in the initial vitally unstable period in order to preserve as much tissues and functions as possible if no active inflammation and compartment syndrome are detective.

ABSTRACT

PURPOSE: Dystrophic calcification occurs in damaged or devitalized tissues in the presence of a normal calcium and phosphorus metabolism. There are many reports on dystrophic calcification caused by injections of various types of drugs. The aim of this report is to highlight the fact that dystrophic calcification can be caused by the injection of a foreign body for aesthetic augmentation. METHODS: This case report describes a patient presenting with dystrophic calcification caused by an injection of an unknown foreign body approximately 50 years ago. An 80-year-old man had localized cellulitis with swelling and ulceration on the dorsum of the left hand. The radiographs demonstrated a 5x3.5x1.7 cm lesion between the first and second metacarpal bones and a 5x2.5x1.5cm lesion in the hypothenar region. The laboratory data and physical examinations were generally within the normal limits. The microscopic examination revealed dead bone fragments and dense collagenous tissue with dystrophic calcification. RESULTS: After surgically removing the masses, the resulting defects were treated with an abdominal flap. The result was satisfactory in terms of symptoms and appearance. CONCLUSION: This case suggests that dystrophic calcification can be caused by an injection of a foreign body for aesthetic augmentation.

ABSTRACT

PURPOSE: Necrotizing fasciitis is a rapid progressive, life-threatening disease. Many organisms have been identified for causative pathogens of necrotizing fasciitis. And necrotizing fasciitis caused by Vibrio vulnificus is a matter of grace concern in Southwest seashore of Korea recently. But concrete analysis between these pathogens was not executed yet. METHODS: Sixty necrotizing fasciitis patients were included in this study. We divided the patients into 2 groups: Group A was the case which Vibrio vulnificus was cultured for causative pathogen of necrotizing fasciitis, and Group B was the case of other organisms. And we analysed each group for treatment, progression and prognosis. RESULTS: There was no significant difference between two groups in total hospital stay but there was a great difference in ICU stay and progression to septic shock. Also, there was a great difference in mortality within 48 hours but there was no difference in mortality of 48 hours after hospital visit. CONCLUSION: This indicates that intial management of necrotizing fasciitis cased by Vibrio vulnificus is the key of treatment. So initial medical management with early surgical intervention is necessary for necrotizing fasciitis.

ABSTRACT

PURPOSE: Chondroid syringoma, previously known as 'mixed tumor of the skin', is a rare benign tumor. It usually presents an asymptomatic solitary firm intradermal or subcutaneous slowly growing nodule. It occurs frequently in the head and neck region of middle-aged men. We would like to report an uncommon chondroid syringoma about the clinical and histologic presentation. about the clinical and histologic presentation. METHODS: We experienced two cases of chondroid syringoma on the nose and the upper lip, each other. Both masses were totally excised with clear margin. RESULTS: On histologic examination, the masses showed a biphasic pattern-an epithelial component exhibiting apocrine/eccrine differentiation and a stromal component exhibiting myxoid/collagenous change-consistent with the diagnosis of chondroid syringoma. There have been no evidence of recurrence and malignant transformation during postoperative follow-up. CONCLUSION: There is no one distinctive clinical feature that is specific for chondroid syringoma. However, it should be included in the differential diagnosis of a solid nodule in head and neck region with long standing duration, such as epidermal inclusion cyst, pilomatrixoma, dermoid cyst, sebaceous cyst, neurofibroma, and basal cell carcinoma.

ABSTRACT

Human cysticercosis is an infestation with C. cellulosae, the larval stage of the tapeworm T. solium. It prevails in regions of poverty and where personal hygiene is poor. They can lodge in almost any tissue, but cysticerci are most frequently found in brain, skeletal muscle, subcutaneous tissues. We experienced a 41-year old male with 5 x 12 cm sized movable non tender brownish hard mass at lateral abdominal wall. The laboratory study didn't show any specific symptoms except peripheral blood eosinophilia and positive parasite ELISA screen for cysticercosis. The ultrasonogram revealed multiple ill-defined mixed echoic inflamatory lesion. Excisied cyst showed multiple severe foul-odor gelatinous subcutaneous mass. Microscopic examination disclosed necrotic body with foreign body reaction, massive eosinophilia and dead parasitic organism, compatible with cysticercosis. There was no evidence of recurrence during 12 months follow-up.

ABSTRACT

The accurate measurement is essential in evaluating the patients in the aesthetic plastic surgery. So many plastic surgeons would have increased the accuracy of photograph. But the results of the efforts are not satisfactory. Now, we can use the 3-D scanner possibly. We want to investigate the reliability of the 3-D scanner by comparing real measurements with the 3-D scanner measurements. Between Apr, 2003 and Nov, 2005, the Korean agency for technology and standards(ATS) investigates the size of 15,576 Korean by real measurements and 5,186 Korean by the 3-D scanner measurements. We selected the measurements of female aged from 20 to 24. These measurements divide into the sections of height, width, thickness, circumference, and compared in each sections. The statistical analysis was performed by STATA 9.0. If the datum points were fixed, unstable and the data was easily measured by the measuring devices such as height, the 3-D scanner measurements were almost coincident with the real measurements. The p-value was statistically not significant. Otherwise, If the datum points were unfixed and the data was measured by a measuring tape, the 3-D scanner measurements were not coincident with the real measurements. The p-value was statistically significant. According to these results, the height can be measured by the 3-D scanner instead of real measurements. But the circumference, thickness and width by the 3-D scanner is almost incompatible with that of the real measurements. The new paradigm of anthropometry is needed.

ABSTRACT

Ingrowing toenail has been treated conventionally by various surgical treatment modlities. However, none of these procedures are perfect to achieve esthetic results with low cost, recurrence, and complication rates. Although mild cases can be treated conservatively, in severe recurrent cases, surgical treatment is preferred. The purpose of this study is to evaluate the effectiveness and safety of using partial matricectomy and paronychial advancement flap for correction of recurrent ingrowing toenail. Eight patients suffering from recurrent ingrowing toenail were operated using partial matricectomy and paronychial advancement flap in our department from August 2004 to August 2005. The number of recurrent episodes ranged from 2 to 5. With digital nerve block, the excision area was marked on nailplate and inflammed lateral nail fold. The horizontally designed paronychial flap considering defect size was effective for wide exposure of the neighboring germinal matrix, which is later to be completely excised or cauterized because remnant germinal matrix made postoperative spicule formation. The nailplate on the affected side was removed about 3-5mm width longitudinally, being cautious not to damage the proximal dorsal nail fold. The same width of the sterile matrix including germinal matrix was excised longitudinally with inflammed granulation tissue and partial lateral nail fold on the affected side. The subcutaneously elevated paronychial flap was advanced to cover the defect and was anatomically sutured with 5-0 nylon sutures. We evaluated our procedure's effectiveness by examining some factors such as cosmetic results, recurrence, spicule formation, postoperative pain and duration of return to normal activities. In eight patients, no complication was observed such as recurrence, severe pain and spicule formation except for 1 case of infection. Postoperative discomfort was minimal. Average duration of return to normal activities was 12 days. Cosmetically the results were acceptable in all patients. The partial matricectomy and paronychial advancement flap for correction of recurrent ingrowing toenail were found to be technically simple, efficient procedure with a relative low recurrence rate and better cosmetic results.

ABSTRACT

PURPOSE: Congenital insensitivity to pain with anhidrosis(CIPA) is a rare form of autosomal recessive peripheral sensory neuropathy. Patients with CIPA show loss of pain sensation, which leads to corneal ulcers and opacities, self-mutilation of the tongue and fingertips, as well as fractures with subsequent joint deformities and chronic osteomyelitis. The purpose of this report is to highlight the fact that pressure sores also are a potential complication of CIPA. METHODS: This case report describes a patient presenting with pressure sores resulting from CIPA. A 5-year-old boy was referred to our department for the treatment of a 5x5cm sacral pressure sore as a result of a hip spica cast applied for the treatment of a left hip joint dislocation. He had a history suggesting CIPA such as multiple bony fractures, mental retardation, recurrent hyperpyrexia, anhidrosis, and clubbing fingers due to oral mutilation. A microscopic examination of the sural nerve showed mainly large myelinated fibers, a few small myelinated fibers and an almost complete loss of unmyelinated fibers. After wound preparation for two weeks, the exposed bone was covered with two local advancement flaps. RESULTS: Two weeks later, complete wound healing was achieved. A 16-month follow-up showed no recurrence. However, the patient presented with a new pressure sore on the left knee due to orthosis for the treatment of the left hip joint dislocation. CONCLUSION: The early diagnosis of CIPA and special care of pressure sores are important for preventing and treating pressure sores resulting from CIPA.

ABSTRACT

Augmentation rhinoplasty is one of the most popular aesthetic procedure in Asians. Numerous alloplastic implants have been used until now, but no accurate comparative analysis about the implant materials has been reported yet. This study in animal model was designed to determine the safety and effectiveness of various implant materials in augmentation rhinoplasty. The 15 x 15 x 2 mm sized square shaped plate of Gore-Tex(R), silicone rubber, and 15 x 15 x 1.5 mm sized Medpor(R) were implanted under panniculus carnosus of the abdomen wall of rat. And tissue specimens including the implant and surrounding soft tissue were obtained by en bloc excision in 6 months after implantation. The implants were estimated in weight and volume, and also the specimens were examined grossly and microscopically. The results revealed that increase of average weight 26.9%, decrease of average volume 55.4% in Gore-Tex(R) implant, increase of each average weight and volume 62.6%, 8.7% in Medpor(R) implant and very slight increase of both average weight and volume 4.7%, 1.1% in silicone rubber implant. Grossly, the Gore-Tex(R) was deformed, Medpor(R) was strongly adherent to surrounding soft tissue and the silicone rubber was well encapsulated and easily peeled off. Microscopically, silicone rubber showed foreign body reaction slightly and there were no inflammatory responses in all alloplastic implants. In our study, silicone rubber showed very proper alloplastic features for augmentation rhinoplasty due to causing no inflammatory response, no physical change, and no deformity.

ABSTRACT

The latissimus dorsi has been used as an excellent donor site for free flap because of many advantages such as reliable anatomy, long pedicle with large-caliber vessels, easiness of dissection, and minimal functional deficit of the donor site. It is also one of the most versatile free flaps due to its carrying skin, muscle, and bone components. Nevertheless, bulkiness limits its use for resurfacing the defect in thin regions such as hand, foot, and anterior tibial area. To reduce its excessive volume when bulk is considered a disadvantage, surgical modifications were introduced: muscle sectioning, reduced musculocutaneous flap, muscle splitting, and thoracodorsal perforator-based cutaneous flap. Although the thoracodorsal perforator-based cutaneous flap excluding muscle component is thinner than others, it also needs secondary debulking procedures to resurface the thin regions. Thinning of the cutaneous flap was successfully performed in paraumbilical perforator-based flap and anterolateral thigh flap. These thinned flaps depend for their circulation on the subdermal plexus originating from their pedicled vessel. Based on their survival concept, we made the thoracodorsal perforator-based cutaneous flap thin and clinically applied it to 7 patients as a free flap. They were all survived and there was no need for secondary debulking procedures. This flap adds the advantage of little bulkiness to the conventional latissimus dorsi flap. However, it has some disadvantages such as technical difficulties in dissection of the perforator, anatomical variation in the location of the perforator, and nonsensory flap.

ABSTRACT

The reduction of nasal bone fracture has been done by a simple procedure. The nasal bone fracture was not a serious problem and patients are usually treated as outpatients. However it is causing increased demand for medical services far cosmetic reasons. We studied the nasal bone fracture by retrospective analysis, it comprising 606 patients with nasal bone fractures in various accidents and treated of Chonnam University Hospital from March 1995 to February 1998. We reviewed and analyzed the medical records and facial bone CT scans of 606 patients. The following results were obtained. 1. The prevalent age group was in the third decade, the most common cause was traffic accidents, while nasal swelling, tenderness, nasal deviation and crepitation were examined 2. The classification of nasal bone fracture was done by facial bone CT. Class 1: Nasal tip depressed fracture(16%) Class 2: Displaced nasal bone fracture without depression(30%) Class 3: Displaces nasal bone fracture with depression(12%) Class 4: Comminuted nasal bone fracture (10%) Class 5: Simple fracture of nasal bone and frontal process of maxilla(14%) Class 6: Comminuted fracture of nasal bone and frontal process of maxilla(11%) Class 7: Nasal bone fracture without displacement(9%) .
