The donor site morbidity of free DIEP flaps and free TRAM flaps for breast reconstruction

This study was undertaken to demonstrate that the deep inferior epigastric perforator (DIEP) flap can provide the well-known advantages of autologous breast reconstruction with lower abdominal tissue while avoiding the abdominal wall complications of the transverse rectus abdominis myocutaneous (TRAM) flap. Eighteen unilateral free DIEP flap breast reconstruction patients were assessed 12-30 months (mean 17.8 months) after surgery. Clinical examination, physical exercises and isokinetic dynamometry were performed preoperatively and two months and one year postoperatively. Intraoperative segmental nerve stimulation, visual evaluation and postoperative CT scans were also used to quantify the damage to the rectus muscle. The 18 patients were then compared with 20 free TRAM flap patients and 20 non-operated controls. Two DIEP flap patients presented with abdominal asymmetry. A limited decrease of trunk flexing strength was noticed but rotatory function was intact. Ten of the TRAM flap patients had umbilical or abdominal asymmetry, bulging or hernias. TRAM flap patients showed a statistically significant reduction in strength to flex and to rotate the upper trunk compared to both the one year postoperative DIEP flap group and the control group. The answers to a questionnaire revealed impairment of activities of daily living for some TRAM flap patients while the activities of all DIEP flap patients were unaffected. Our data demonstrate that the free DIEP flap can limit the surgical damage to the rectus abdominis and oblique muscles to an absolute minimum. We believe it is worthwhile to spend extra operative time, the main disadvantage of this technique, to limit late postoperative weakness of the lower abdominal wall.

Better cosmetic results and comparable quality of life after skin-sparing mastectomy and immediate autologous breast reconstruction compared to breast conservative treatment

Preoperative chemotherapy (PCT) can be used in large primary breast cancer to facilitate breast conservative surgery (BCS). Cosmetic results of BCS are influenced by the size of the residual tumour, relative to the size of the breast. After mastectomy, immediate breast reconstruction (IBR) with autologous tissue provides excellent cosmetic outcome and has proven to be safe in breast cancer patients. Besides improving overall and disease free survival, Quality of Life (QoL), body image and cosmetic outcome are also important issues after treatment for breast cancer. In this study, Health-Related-Quality of Life (HRQL) and body image were evaluated, in patients treated with PCT, followed by BCS, or skin-sparing mastectomy (SSM) and perforator-flap breast reconstruction. Additionally, clinical observers assessed cosmetic outcome. All participants were evaluated by the Medical Outcomes Study (MOS) 36-item Short Form Health Status Survey (SF-36, 36 items) and a study-specific questionnaire. An external panel evaluated standardised photographs of the breasts. For all patients, norm-based scores of physical and mental health state are comparable with the general population, except for vitality (VT) score, which is somewhat lower. No significant differences can be observed between both groups. The majority of the patients were satisfied with the appearance of their breasts. The cosmetic results, assessed by the clinical team, were significantly better for patients having IBR, compared to BCS. The mean score was 7.5/10 for IBR, versus 6.0/10 for BCS (p<0.0001).Breast conserving treatment or mastectomy with reconstruction may yield comparable results of QoL, but cosmetic outcome is better after SSM and perforator-flap reconstruction. Patients must be offered both options, and clinicians should stress that both are equally effective.

The use of pedicled perforator flaps for reconstruction of lumbosacral defects.

&NA; Large lumbosacral defects remain a difficult challenge in reconstructive surgery, especially in the nonparaplegic patient. Traditional options for closure include local rotation or transposition flaps and musculocutaneous flaps. These flaps, however, are not an optimal option in previously irradiated or operated areas, or in cases of large defects. Application of the perforator principle to the traditional musculocutaneous flap creates perforator flaps, which are an additional tool in the treatment of these defects in the nonparaplegic patient. A large amount of healthy, wellvascularized tissue can be transferred on one perforator without sacrificing important underlying muscles. The are of rotation is also larger than in traditional flaps. The authors present an anatomic overview of three types of pedicled perforator flaps: the superior gluteal artery perforator flap, the lumbar artery perforator flap, and the intercostal artery perforator flap. They also report 4 patients in whom a pedicled perforator flap was used to reconstruct a large lumbosacral defect. Roche NA, Van Landuyt K, Blondeel PN, Matton G, Monstrey SJ.

Obtaining Rigidity in Total Phalloplasty: Experience With 35 Patients

PURPOSE The combination of a neourethra and erection prosthesis in a single neophallus in the female-to-male transsexual remains a challenge. The outcome reported in the literature is disappointing. We report our experience with 35 patients. MATERIALS AND METHODS Between August 1996 and December 2001, 35 patients underwent implantation surgery. A 1-piece hydraulic Dynaflex prosthesis (American Medical Systems, Minnetonka, Minnesota) was used in 10 patients, while a 3-piece hydraulic CXM and CX (American Medical Systems) prosthesis was placed in 9 and 16, respectively. The 1-piece model was withdrawn from the market in 1997. Thereafter a 3-piece prosthesis was implanted. RESULTS Of 10 patients in the 1-piece group prosthesis implantation was uneventful in 8. In 2 patients with technical failure the prosthesis was replaced, including 1 in whom the new prosthesis was removed due to infection and successfully replaced by a 3-piece prosthesis. To date at a mean followup of 3.5 years 9 patients have a 1-piece hydraulic prosthesis in place. In the 3-piece prosthesis group of 25 patients implantation was uneventful in 20. In 1 patient infection and partial necrosis of the neophallus developed, 2 had infection, in 1 a cylinder perforated the tip of the phallus and in 1 technical failure occurred. Of the latter 4 patients the prosthesis was replaced successfully in 2 patients, while the other 2 are on the waiting list. The patient with partial necrosis of the phallus is no longer a candidate for an erection prosthesis. To date at a mean followup of 1.8 years 23 patients have a 3-piece hydraulic prosthesis in place. A single patient in the 1-piece group has a 3-piece CX prosthesis. CONCLUSIONS Good results were observed after implantation of the Dynaflex prosthesis in patients who underwent total phalloplasty. This model is no longer available today. For the more complex 3-piece CX and CXM prostheses implantation results are comparable to those of the 1-piece model.

Phalloplasty: a valuable treatment for males with penile insufficiency

OBJECTIVES To apply a phalloplasty technique used in female-to-male transsexual surgery in male patients with penile insufficiency. METHODS Seven male patients (aged 15 to 42 years) were treated with phalloplasty (6 with radial forearm free flap and one with anterolateral thigh flap) between March 2004 and April 2006 (follow-up, 9 to 34 months). All patients suffered psychologically from their condition, with low self-esteem and sexual and relational dysfunction. They were evaluated by a sexologist-psychiatrist before and after surgery. Erectile implant surgery is offered approximately 1 year after the phallic reconstruction. RESULTS There were no complications concerning the flap. Two complications were reported in the early postoperative period. Two patients developed urinary complications (stricture and/or fistula). Patient satisfaction after surgery was high in 6 cases and moderate in 1 case. Psychological evaluation confirms this, especially on the self-esteem level. Four patients underwent erectile implant surgery. In 2 patients the erectile implant had to be removed. CONCLUSIONS This success has convinced us that phalloplasty is a valuable treatment for penile insufficiency. It has good results in terms of patient self-esteem and sexual well-being. This technique opens new horizons for the treatment of penile agenesis, micropenis, crippled penis, shrivelled penis, some disorders of sexual development, traumatic amputations, and cloacal exstrophy.

Autologous breast augmentation by pedicled perforator flaps.

A technique is described for autologous breast augmentation based on perforator flaps of the lateral chest wall. Raising these flaps as perforator flaps implies minimal donor site morbidity; however, the price to pay is a scar underneath the armpit extending from the lateral end of the inframammary fold onto the back. This scar can be relatively well hidden underneath the arm and in the brassiere. Indications depend on the aversion of the patient against prostheses and the extent of available tissue versus the desired augmentation. As typical indications, we would consider the occasional developmental asymmetry, autologous augmentation after contralateral breast reconstruction, or contour surgery in the bariatric patient.

Impact of voice in transsexuals

ABSTRACT Transsexualism implies that an anatomically normal individual feels that he or she is actually a member of the opposite sex. Treatment usually includes real-life experience along with hormone therapy and sex reassignment surgery. Voice modification surgery may be necessary, as pass ability in general is still in a large extent dependent on the aspects of voice in transsexual people. Often male-to-female patients report being addressed in telephone conversations as their genetic gender, which is experienced as a disability. The purpose of this study was to evaluate the impact of voice on the quality of life in transsexuals. In order to detect the disability caused by a voice disorder, the validated assessment method the Voice Handicap Inventory (VHI) was used. An additional question about the way patients were addressed in a telephone conversation was added. As part of a study describing general health in transsexual persons, done at the Ghent University Hospital Belgium, a total of 48 patients were evaluated. In female-to-male transsexuals the median scores were very low, suggesting testosterone treatment led to an acceptable voice alteration. A higher serum LH level was significantly correlated with higher total, functional and emotional VHI scores. In male-to-female transsexuals the scores were significantly higher than those of the female-to-male transsexuals, but still there was no indication of a real disability/handicap. The extra telephone question was scored higher suggesting male-to-female transsexuals did experience a disability caused by their voice. From this study it is concluded that the VHI values did not demonstrate a handicapping effect.

Surgical-technical aspects of the free diep flap for breast reconstruction

The transverse rectus abdominis myocutaneous (TRAM) flap has been the gold standard for breast reconstruction in the last decade. The free deep inferior epigastric perforator (DIEP) flap and the superior gluteal artery perforator (S-GAP) flap are both refinements or “upgrades” of the conventional myocutaneous lower abdominal and gluteal flaps. The harvested skin and fat paddles are similar but none of the underlying muscle is sacrificed. The preservation of the continuity of the muscle fibers, the muscles motor innervation, and the vascularization by collateral blood vessels ensures normal function of the muscle, only split during surgery, and the muscles that interact with it. The free DIEP and S-GAP flap have comparable complication rates to the free TRAM flap, making these flaps safe and reliable techniques. Although still a very low risk is involved, especially total flap loss, free perforator flap surgery for breast reconstruction is the surgical technique in which the least perioperative and postoperative complications are involved and this offers the patient the best long-term aesthetic result. Additionally, by sparing the donor site muscle and restoring sensation, the normal breast anatomy is imitated in the best possible way; except for a donor site scar, no other damage is caused to the body. The free DIEP flap is the first choice for breast reconstruction because of the inherent characteristics of the lower abdominal wall.

Reconstructive Surgery for Severe Penile Inadequacy: Phalloplasty with a Free Radial Forearm Flap or a Pedicled Anterolateral Thigh Flap

Objectives. Severe penile inadequacy in adolescents is rare. Phallic reconstruction to treat this devastating condition is a major challenge to the reconstructive surgeon. Phallic reconstruction using the free radial forearm flap (RFF) or the pedicled anterolateral thigh flap (ALTF) has been routinely used in female-to-male transsexuals. Recently we started to use these techniques in the treatment of severe penile inadequacy. Methods. Eleven males (age 15 to 42 years) were treated with a phallic reconstruction. The RFF is our method of choice; the ALTF is an alternative when a free flap is contraindicated or less desired by the patient. The RFF was used in 7 patients, the ALTF in 4 patients. Mean followup was 25 months (range: 4–49 months). Aesthetic and functional results were evaluated. Results. There were no complications related to the flap. Aesthetic results were judged as “good” in 9 patients and “moderate” in 2 patients. Sensitivity in the RFF was superior compared to the ALTF. Four patients developed urinary complications (stricture and/or fistula). Six patients underwent erectile implant surgery. In 2 patients the erectile implant had to be removed due to infection or erosion. Conclusion. In case of severe penile inadequacy due to whatever condition, a phalloplasty is the preferred treatment nowadays. The free radial forearm flap is still the method of choice. The anterolateral thigh flap can be a good alternative, especially when free flaps are contraindicated, but sensitivity is markedly inferior in these flaps.

The effect of ultrasound-assisted liposuction and conventional liposuction on the perforator vessels in the lower abdominal wall

Scientific reports of clinical in vivo research into the effects and side-effects of ultrasonic-assisted liposuction (UAL) are scarce. Advocates of UAL claim that the damage to vascular and nervous structures is limited and even less than with conventional and/or tumescent liposuction (CL). The effect of tumescent infiltration alone and combined with either CL or UAL was assessed by performing injection studies of the panniculus adiposus of the lower abdominal wall of 20 fresh cadavers and five abdominoplasty specimens. Besides the control and infiltration groups (n=5 in each), there was an additional group of ten cadaver flaps and five abdominoplasty flaps that underwent infiltration followed by UAL in the right half of the flap and infiltration followed by CL in the left half of the flap. Radiographs of these flaps were shown to a blinded panel of ten plastic surgeons, who were asked to evaluate and compare the damage on the basis of the number and magnitude of contrast-medium extravasations in the flap. Vascular damage to the perforating vessels was seen even after infiltration alone, although it was very limited. A variable amount of damage (ranging from little to extensive) was observed in the CL and UAL groups. Statistical analysis of the judgments of the observers could not show that either technique was less damaging than the other. UAL is, therefore, probably more beneficial to the surgeon than to the patient. The financial investment in the device is justified for surgeons with large liposuction practices, mainly, and probably solely, because of the reduced physical strain for the surgeon.
