Extreme bone lengthening using distraction osteogenesis after trauma: a case report.

We are reporting herein the result of a 22 cm tibial lengthening after using an acute shortening technique with acute temporary angulation for salvage of a posttraumatic lower limb injury. The patient was referred to our center 2 weeks after a Gustilo IIIB open complex injury to the lower limb that included bone and soft-tissue loss. After surgical debridement, the tibial gap was 22 cm and the soft-tissue defect on the anterior aspect of the calf measured 12 x 20 cm. An acute shortening using a 50 degrees angulation (apex posteriorly) of the tibia in an Ilizarov frame was done after a full assessment of all reconstructive surgical options. After complete wound healing, a progressive correction of the angulation was done. Bilevel tibial distraction at a rate of 1.75 mm/day restored the original lower limb length. The 22 cm tibial elongation included 17 cm proximal lengthening and 5 cm distal lengthening. The fractures consolidated after 371 days, all wounds had closed, and no signs of osteomyelitis were present. Good aesthetic and functional results were obtained. The patient had no leg discrepancy compared to his normal limb and he returned to his previous occupation as a garage mechanic and to his favorite sport, boxing. To our knowledge, this is the first report in the English literature of tibial lengthening of this magnitude following acute trauma.

Early nonsurgical correction of congenital auricular deformities.

Congenital auricular deformation is not an uncommon phenomenon, and it may cause substantial annoyance to the growing child. Many parents of affected children will seek surgical correction of the deformed auricles. The variety of techniques that have been described for the correction of this anomaly suggests that none has been considered satisfying. The consequent possible surgical complications should also be considered, when the surgical procedure can be replaced by an effective conservative treatment. The authors describe their experience using early splinting for congenital auricular deformities. Fifty-two newborn infants with lop, prominent, Stahl's, and constricted ears referred to us by the neonatal department staff were enrolled in this study. Putty Soft, a vinyl polysiloxane impression material, has been used for early molding of the auricles. Surgical tapes were used for the fixation of the mold and to fix the auricle to the scalp. The results were evaluated by one of the parents and by a layperson (medical student) 6 months after completion of the procedure. The above-described early splinting procedure was applied onto 92 auricles of 52 newborn infants aged 1 to 10 days, mostly around day 3. The mean treatment time was 6.8 weeks. All treated auricles were improved, 87 percent were rated as excellent improvement, and there were no complications related to the treatment. The authors conclude that early splinting of deformed auricles should be offered to parents of affected children, and the awareness of this procedure by neonatologists, pediatricians, and nursery staff should be increased.

The distally based sural musculoneurocutaneous flap for treatment of distal tibial osteomyelitis.

BACKGROUND: The treatment of distal tibial osteomyelitis represents a challenge for orthopedic and plastic surgeons. The affected tissues should be debrided and good vascularized tissue should cover the defect, but the option of a muscle flap covering the area is limited. Free flaps are used but require longer operating time and experience with microsurgery, may result in donor-site morbidity, and sometimes add bulky tissue to the area. The authors present their experience with a sural musculoneurocutaneous flap for the treatment of chronic osteomyelitis of the distal tibia. METHODS: Over a 2-year period, nine distally based sural musculoneurocutaneous flaps were used in the treatment of chronic osteomyelitis of the distal tibia. Four patients had comorbid conditions (smoking, diabetes mellitus, venous insufficiency, or obesity). The clinical aspect was represented by drainage sinuses located in the distal part of the tibia. Five patients had postsurgical scars on the lateral malleolar region and one had medial and lateral malleolar scarring. Three patients had an Ilizarov device at the time of wound coverage. RESULTS: All wounds were closed successfully. Dehiscence surrounding the flap was encountered in a single case that was attributable to inadequate bone debridement; this flap was raised to allow extending the debridement, and a local medial fasciocutaneous flap completed wound coverage. Distal tip necrosis of the flap was encountered in two cases. CONCLUSIONS: The sural musculoneurocutaneous sural flap was successfully used for treatment of distal tibia osteomyelitis. Although it is believed that lateral malleolar scars might compromise the flap, the flaps in the authors' series survived. This flap can also be applied to patients with external fixators without removing the apparatus.

A side-by-side prospective study of intense pulsed light and Nd:YAG laser treatment for vascular lesions.

Recently, lasers and light systems are used more for the treatment of vascular lesions due to their noninvasiveness, ease of use, and short recovery time. This side-by-side prospective study compares results, satisfaction, and complications after intense pulsed light (IPL) and Nd:Yag laser treatment of small vascular lesions. Twenty-five patients with telangiectases, leg veins, or cherry angiomas underwent treatment of the same category of lesion in the same area. One year after completing treatment, patients were asked to report their satisfaction level after comparing digital photos before and after treatment; 72% felt they had good to excellent results after Nd:Yag treatment, while only 48% felt the same after IPL. The most common side effect after Nd:Yag was hyperpigmentation. Satisfaction level was significantly higher after Nd:Yag than after IPL. Patients with telangiectases, cherry angiomas, or leg veins <1 mm were more satisfied after IPL, while those with leg veins >1 mm were more satisfied after Nd:Yag. Overall, satisfaction with treatment of vascular lesions was greater with Nd:Yag although this method was more painful.

Multimodality gynecomastia repair by cross-chest power-assisted superficial liposuction combined with endoscopic-assisted pull-through excision.

Numerous methods of gynecomastia repair have been described to accomplish removal of breast tissue. Our multimodality surgical approach for the treatment of gynecomastia combines the use of power-assisted superficial cross-chest liposuction with direct pull-through excision of the breast parenchyma under endoscopic supervision. Seventeen patients, aging 17-39, underwent this multimodality approach. According to Simon's grading, 3 patients had grade 1, 5 had grade 2a, 6 had grade 2b, and 3 had grade 3 gynecomastia. Power-assisted liposuction was performed with a 3- or 4-mm triple-hole cannula inserted through the contralateral periareolar medial incision to suction the contralateral prepectoral fatty breast. At the end of the liposuction, the fibrous tissue was easily pulled through the ipsilateral stab wound and excised under endoscopic control. Follow-up time ranged from 6 to 34 months. The amount of fat removed by liposuction varied from 100-800 mL per breast, and the amount of breast parenchyma removed by excision varied from 20-110 g. All patients recovered remarkably well. No complications were recorded. All patients were satisfied with their results. This technique enables an effective treatment of both the fatty and fibrous tissue of the male breast and avoids skin redundancy due to skin contraction. A smooth masculine breast contour is consistently achieved without the stigma of this type of surgery.

Hair removal using intense pulsed light (EpiLight): patient satisfaction, our experience, and literature review.

Applications for intense pulsed light (IPL) for hair removal are gaining favor among other methods, including lasers, because of its noninvasive nature, versatility regarding different skin and hair types, safety, and ease of use. Hair removal using IPL was performed from January 2002 to December 2003 on 108 consecutive patients. Eighty of these patients answered a questionnaire and were enrolled in the study group. The investigated parameters were hair and skin type, number of pulses, fluence, pulse duration, pulse delay, the filters used, and the treated area. The patient assessment of improvement (satisfaction) rate was graded from 1 to 5 points: 1, worse; 2, no improvement; 3, mild improvement; 4, good result; and 5, excellent result. The patients had between 1 and 13 treatments most of them during 2 to 6 sessions. Sixty-seven percent of the patients reported no complications. Prolonged erythema for more than 7 days was reported by 16.25%, blisters by 6.25%, temporary hyperpigmentation by 8.75%, leukotrichia was present in 1 case, and 1 case of persistent hypopigmentation was noted in a young girl. An increased number of complications and a decreased satisfaction rate were noted with higher skin types, but it was not statistically significant. Patients who underwent fewer treatments (1-3 treatments) were more satisfied compared with those who had more than 7 treatments (P < 0.02). Sixty percent of the patients rated their satisfaction to be good to excellent and 65% would ill recommend this treatment to their friends. To minimize the complication rate the authors found that the preset parameters should be adjusted at every treatment session according to the skin response at the previous one. Permanent hair removal cannot be guaranteed and it is not possible to predict the improvement rate. Nevertheless, based on patient satisfaction rate in this study, the authors recommend using IPL for hair removal.

Enhancing the take of injected adipose tissue by a simple method for concentrating fat cells.

Injection of aspirated fat for the correction of tissue defects is a common procedure in plastic surgery. The reported rates of fat cell survival vary greatly in the medical literature, and different techniques of harvesting, processing, and reinjecting the fat cells are claimed to be responsible for these differences. However, there is no agreement concerning the best way to process the harvested fat before reinjection. The present study was initiated to examine and evaluate the effect of a simple method of isolating the fat particles on the outcome of fat graft survival. In this study, the nude mouse model was used to examine the survival and take of the fat graft concentrated before injection by the cumbersome recommended closed centrifugation technique in comparison with the authors' recommended open method, using an operating room cotton towel as a platform for concentrating the fat cells and separating them from fluids, oil, and debris. One milliliter of concentrated human fat cells preprocessed by towel separation was injected into the nuchal subcutis of 11 nude mice in the study group, and the same amount of fat that was preprocessed by centrifugation was injected into 11 control mice. Injected fat survived in both groups. No significant differences were found regarding fat graft weight and volume, although a tendency for better survival was noticed in the experimental group. Histologic evaluation of the grafts revealed significantly less fibrosis within the study group, meaning that the quality of the fat grafts was better. The authors found this method to be simple, cheap, and friendly to the surgeon in comparison with traditional processing using the centrifuge.

The effect of interleukin-8 on the viability of injected adipose tissue in nude mice.

Adipose tissue injection as a free graft for the correction of soft-tissue defects is a widespread procedure in plastic surgery. The main problem in achieving long-term soft-tissue augmentation is partial absorption of the injected fat and hence the need for overcorrection and re-injection. The purpose of this study was to improve the viability of the injected fat by the use of interleukin-8. The rationale for the use of interleukin-8 was its abilities to accelerate angiogenesis and attract inflammatory cells and fibroblasts, providing the injected adipocytes more feeding vessels and a well-established graft bed to enhance their viability. Human adipose tissue, obtained by suction-assisted lipectomy, was re-injected into the subcutis in the scalp of nude mice. Interleukin-8 (0.25 ng) was injected subcutaneously to the scalp as a preparation of the recipient site 24 hours before the fat injection and was added to the fat graft itself (25 ng per 1 cc of injected fat). In the control group, pure fat without interleukin-8 was injected and no interleukin-8 was added for the preparation of the recipient site. One cubic centimeter of fat was injected in each animal in both the study and control groups. There were 10 animals in each group. The animals were euthanized 15 weeks after the procedure. Graft weight and volume were measured and histologic evaluation was performed. In addition, triglyceride content and adipose cell sizes were measured as parameters for fat cells viability. Histologic analysis demonstrated significantly less cyst formation in the group treated with interleukin-8. No significant differences were found between the groups with regard to graft weight and volume or the other histologic parameters investigated. No significant differences were demonstrated in adipose cell sizes and their triglyceride content. In conclusion, less cyst formation, indicating improved quality of the injected fat, can be obtained by the addition of interleukin-8. Further studies of various dosages of interleukin-8 and their long-term effect are required before these encouraging results could be applied clinically.

Four parallel flaps for correction of a wide forehead defect.

A simple method for closure of a defect in the forehead area by four parallel flaps along the forehead wrinkle lines is illustrated. The main advantage of this method lies in its simple design, which enables the surgeon to close large defects with no elevation of the eyebrow, while preserving the hairline, and most of the suture lines are parallel to the forehead wrinkle lines.

Acute shortening: modular treatment modality for severe combined bone and soft tissue loss of the extremities.

BACKGROUND: Acute shortening, using the Ilizarov technique followed by progressive lengthening, is one of the methods used to deal with complex fractures combined with severe soft tissue injuries. METHODS: We have summarized 12 patients who underwent acute shortening and stabilization using the Ilizarov frame. Nine of them underwent progressive lengthening to restore the length. For three patients, angulation of the bone segments was performed to save them from excessive bone debridement. RESULTS: Total wound closure and bone regeneration were achieved in all our patients. Five patients had pin-tract infection without involvement of the bone, and no major complications were noted. CONCLUSION: Using this technique, we found some advantages. First, there is less need for free and local flaps. Second, there is a decrease in the operating time and donor-site morbidity (important for patients with multiple organ trauma). Third, it provides a good option for restoring defects in severe cases with combined bone and soft tissue defects in the same session. Fourth, its implementation for short bone defects (< 3 cm) gives acceptable aesthetic and functional results. Fifth, angulation of the segments and subsequent graduated correction of misalignment reduces the length of shortening needed in patients with severe soft tissue loss by sparing the bone from unnecessary debridement. Sixth, it permits definitive treatment using an external fixator device, enabling the possibility of early functional loading. On the basis of our experience, we suggest adopting this method for functional limb salvage after extensive complex high-energy injuries.

Fate of exposed breast implants in augmentation mammoplasty.

Exposure of silicone breast implants usually leads to infection and extrusion. According to the literature, implant extrusion rates are not higher than 2% 1 and removal of the implant is recommended. 2 During the past 3 years, the authors dealt with eight implant exposures (six women: two cases of bilateral exposure and four cases of unilateral exposure). All the pockets were infected. Patients were offered two alternatives: immediate removal of the implant and reimplantation after a few months or conservative treatment with an effort to close the exposed area after the discharge stopped. All the patients in this study chose the latter alternative. Four out of eight implants were saved. The authors had to remove the other four. The average follow-up of these women was 2 years and there were no signs of capsular contracture or any other problems. According to this series, 50% of eight exposed breast implants could be saved with conservative treatment.
