The use of alloplastic materials in secondary rhinoplasties: 32 years of clinical experience.

BACKGROUND: A retrospective evaluation of the authors' 32 years of experience in revision rhinoplasty is presented. The authors suggest that iatrogenic nasal deformities are studied under four groups on the basis of their location and the affected structures: lower third, middle third, upper third, and combined deformities. The authors also present the vertical columellar incision for insertion of alloplastic implants and cartilage grafts, a genuine approach avoiding contamination with the nasal flora. METHODS: A total of 182 cases were studied, as follows: lower third (n = 81), middle third (n = 65), upper third (n = 17), and combined (n = 19) deformities. The mean age of the patients was 40 years. RESULTS: Our follow-up was a minimum of 2 years, and some of the cases with Proplast implants have been followed for as long as 21 years. During this rather long follow-up, only two of the Proplast implants had to be removed (one because of an acute infection and the other because of a chronic infection causing extrusion after 5 years). CONCLUSIONS: The authors have always preferred to use autogenous cartilage grafts for tip deformities and Proplast implants for middle and upper third saddle nose deformities whenever necessary. Their long-term results with Proplast for more than 20 years show that alloplastic materials may be as reliable as autogenous implants if the surgical principles are met and the cases are carefully selected.

Axial pattern composite prefabrication of high-density porous polyethylene: experimental and clinical research.

Currently, various alloplastic materials are being used for reconstruction of three-dimensional structures, and high-density porous polyethylene is so far the best and the most commonly used material. Various indications for high-density porous polyethylene have been defined for closure of craniofacial defects, correction of congenital anomalies, and aesthetic augmentations. A common property of various studies published so far is that after being fixed to the bone or underlying structures, high-density porous polyethylene has been covered primarily or by skin flaps. For reconstruction of complex three-dimensional structures such as the ear and nose, the success of current methods is limited by the thinness and pliability of the skin flap. In this study, the authors' aim was to investigate the graftability of high-density porous polyethylene after prefabrication with an axial pedicle and to explore possible clinical applications in light of the new data obtained. In the experimental study, three-dimensional implants (rectangular prism) carved from high-density porous polyethylene were prefabricated using bilateral superficial epigastric arteries and veins of 25 New Zealand rabbits. After a waiting period of 2 to 6 weeks in five groups, control samples were obtained and the prefabricated implants that had been left in place were directly grafted. The results showed that high-density porous polyethylene was vascularized 75 percent after 4 weeks and 90 percent after 5 weeks, and 95 percent of the grafts had survived after 8 weeks. In the clinical study, three nose defects, three ear defects, and one hard palate defect in seven patients ranging in age from 21 to 72 years were reconstructed using the same method. High-density porous polyethylene has been prefabricated and directly grafted for the very first time on a clinical basis. No serious complications have been observed, except for minimal graft loss in two patients. It is obvious that full-thickness skin grafts that are thinner than flaps will adapt better to the fine details of high-density porous polyethylene and will highly increase the detail obtained in the reconstruction of three-dimensional defects.

Soft tissue hemangioma formation within a previously excised intraosseous hemangioma site.

Intraosseous hemangiomas are rare benign lesions, occurring often in verbrata and skull. These lesions can present in the head and neck region being the next most common site with a predominance of the mandible. Herein we report a patient who experienced a soft tissue hemangioma occurring at the previous surgical site three years after the first operation.

Incidental idiopathic calcinosis cutis in a rhytidectomy patient.

Calcinosis cutis, deposition of insoluble calcium salts in cutaneous tissues, is an uncommon disorder. This condition can be classified as metastatic, dystrophic, idiopathic, and iatrogenic based on the pathogenesis of the deposition. Whereas dystrophic calcinosis cutis is a fairly common condition, idiopathic cases are very rare. Distinct cutaneous anatomic areas, the vulva, scrotum, penis, and breast, have been reported to develop this disorder. Nevertheless, our case who had idiopathic calcinosis cutis in her neck may be a proof that this condition is not confined to genitals or the breasts and can be seen all over the skin.

Angiokeratoma circumscriptum.

Angiokeratoma circumscriptum is one of five types in the group of the angiokeratomas. These lesions are usually present at birth and are not related with systemic diseases. Angiokeratoma circumscriptums are hyperkeratotic papules or nodules occurring frequently unilaterally on the leg. These lesions are very rare and very few cases have been reported since its first description. It is of particular clinical importance because of its morphologic similarities to malignant skin tumors such as malignant melanoma or pigmented basal cell carcinoma. Therefore, this rare but significant lesion must be recognized by physician and surgeons who manage skin tumors.

Late-onset superficial lymphatic malformation: report of a case and review of the literature.

BACKGROUND: Superficial lymphatic malformations are predominantly developmental malformations of infancy, but they may arise at any age. OBJECTIVE: To describe a patient with a late-onset superficial lymphatic malformation. METHODS: Case report and literature review. RESULTS: A 53-year-old woman was evaluated for a colored lesion that developed spontaneously on the anterior abdominal wall. The lesion was treated by surgical excision. Findings on histopathologic examination of the specimen were consistent with superficial lymphatic malformation. There was no recurrence of the lesion at 4 months after the operation. CONCLUSION: Superficial lymphatic malformations can develop in adults spontaneously without the presence of any predisposing condition. Because the majority of such late-onset malformations reported in the literature are localized lesions similar to the one in our patient, surgical removal with inclusion of subcutaneous tissue usually results in cure without recurrence.

Intravenous pyogenic granuloma of the hand.

BACKGROUND: Intravenous pyogenic granuloma is the intravasal counterpart of cutaneous pyogenic granuloma. This rare, benign lesion appears clinically as a subcutaneous nodule usually located in the upper extremity or neck in middle-aged people. It is hard to make an exact diagnosis on clinical basis, and there is a risk of recurrence because of undertreatment. OBJECTIVE: To report a case of an intravenous pyogenic granuloma located in the hand and to describe the clinical and histopathologic features of this rare vascular tumor. METHODS: An operation was performed on a 58-year-old female who presented with a small, painless mass in the right palm, and the pathologic examination revealed an intravenous pyogenic granuloma. CONCLUSION: This rare lesion should be differentiated from a regular pyogenic granuloma and should be excised with the vein segment to avoid recurrence.

Total lower lip reconstruction using sensate composite radial forearm flap.

In modern plastic and reconstructive surgery, shape and function must be considered together. These are the most important goals of any operation. There are a lot of techniques that have been reported for total lower lip reconstruction. It is believed that the radial forearm flap is the most suitable technique for lower lip and chin reconstruction after tumor excision so as to achieve better shape and functional results. The sensate radial forearm-palmaris longus free flap was used for total lower lip reconstruction in 17 patients with lower lip carcinoma with a mean age of 51 years. Two of the patients were female, and 15 were male. All the patients had squamous cell carcinoma. The patients were followed up for 1 to 3 years. Complications of these operations were partial superficial flap loss in 1 patient, partial graft loss in the donor areas of two flaps, and infection in only 1 patient. Wound dehiscence, fistula formation, suture abscesses, or sialocele was not seen in any patient. In this study, the aim was to demonstrate that the sensate radial forearm flap could produce acceptable esthetic results, good sphincteric function, and sensation in the early period after surgery.

Reconstruction of heel defects with a proximally based abductor hallucis muscle flap.

The main goals of reconstruction of plantar defects include appropriate soft tissue coverage to facilitate weight bearing, and sufficient blood supply to prevent osteomyelitis. This retrospective study presents the clinical results of 11 patients who received a proximally based abductor hallucis muscle flap for coverage of calcaneal defects. The mean patient age was 43 years (range, 23-69 years). Four patients were women and 7 were men. Seven were non-diabetic patients with neurologic deficits of varying etiology or patients who had pressure ulcers after prolonged hospitalization. Four patients had diabetes with or without neurological deficits, and 6 patients had calcaneal osteomyelitis. In 6 patients, the origin of the muscle was dissected and rotated over the defect. The flap was elevated as an island flap in 5 patients. Postoperatively, partial flap loss was observed in 1 patient, who was then treated successfully with a fasciocutaneous flap. Two patients developed seroma and hematoma at the donor site, which resolved uneventfully after surgical drainage. The 6 patients with calcaneal osteomyelitis showed no recurrence after 1 year of follow-up. The abductor hallucis muscle flap provides enough stability and sufficient blood supply for calcaneal defects up to 3 x 6 cm.
