The third suture in MACS-lifting: making midface-lifting simple and safe.

BACKGROUND: The minimal access cranial suspension (MACS)-lift is a short scar rhytidectomy with vertical purse string suture suspension of the facial tissues. It exists in a simple and extended version. The simple MACS-lift achieves a vertical lifting of neck and lower half of the face with two purse string sutures. The action of a third, malar suture gives additional correction of the middle third of the face, and results in the extended MACS-lift. OBJECTIVE: To draw attention to the power and advantages of the 'third' malar suture in the extended MACS-lift in achieving volumetric restoration of the midface, softening of the nasolabial fold and enhancing support of the lower eyelid. METHODS: The core principle of this technique is the use of strong purse string sutures in a pure antigravitational direction for correction of the ageing neck and lower two-thirds of the face. In a simple MACS-lift the neck is corrected by a first narrow vertical purse-string suture. The volume of jowls and cheeks is repositioned in a cranial direction with a second, slightly oblique purse string suture. To achieve better control over the midface an extended MACS-lift is performed by adding a third malar vertical purse string suture between the paracanthal area and the malar fat pad. RESULTS: 557 MACS-lift procedures have been performed by the two senior authors, of which 183 were simple and 374 extended. A retrospective review of this technique revealed high patient satisfaction, only one major complication and a minor complication rate of 6%. Both versions of the technique deliver a vertical vector correction of sagged facial features. The third suture restores the volume of the midface and malar mound and provides strong support of the lower eyelid. CONCLUSIONS: The third suture in the MACS-lift short scar rhytidectomy produces a natural midface lifting through a short scar, with adequate softening of the nasolabial fold and good support of the lower eyelid.

The versatility of the pudendal thigh fasciocutaneous flap used as an island flap.

The pudendal thigh flap is a sensate fasciocutaneous flap based on the terminal branches of the superficial perineal artery, which is a continuation of the internal pudendal artery. Several authors have reported using this axial patterned flap in a bilateral fashion to reconstruct the vagina, mostly in patients with vaginal atresia. The technique is simple, safe, and reliable, and no stents or dilators are required. The reconstructed vagina has a natural angle and is sensate. The donor site in the groin can be closed primarily with an inconspicuous scar. The distinct advantages of this flap widen its indications to several other pathologies. In this article, the authors report on the bilateral use of the flap to reconstruct a vagina in patients with congenital atresia (n = 8) and after oncological resection (n = 5). Furthermore, the versatility of this island flap is also demonstrated by its use in a unilateral fashion in patients with recurrent or complex rectovaginal fistulas (n = 4) and in two patients with a defect of the posterior urethra in a heavily scarred perineum. All 31 pudendal thigh flaps survived completely. Some wound dehiscence was observed in two patients. Two other patients required a minor correction at the introitus of the vagina. The functional outcome was excellent in all patients, despite the presence of some hair growth in the flaps. This article discusses the expanding indications of this versatile flap and the refinements in operative technique.

The superior gluteal artery perforator flap: an additional tool in the treatment of sacral pressure sores.

We describe the use of a large skin-subcutaneous tissue flap based on one perforator of the superior gluteal artery (SGA) to reconstruct large midline posterior defects in one stage. The integrity of the gluteus muscles is preserved and we feel this is particularly important in non-paralysed patients. Donor sites were always closed primarily. Use of the superior gluteal artery perforator (SGAP) flap preserves the entire contralateral side as a future donor site. On the ipsilateral side, the gluteal muscle itself is preserved and all flaps based on the inferior gluteal artery are still possible. We recommend this flap in an area where reconstructive possibilities are limited, as it preserves other reconstructive flap options, both on the ipsilateral and contralateral sides.

A simple mathematical formula for custom-made croissant tissue expanders.

The popularity of croissant-type tissue expanders has increased steadily during the past 5 years. Croissant-shaped expansion offers the advantage of creating a tailored skin flap that is advanced easily into an elliptical skin defect without the formation of dog-ears or without the need for backcuts in the expanded flap. Because the majority of lesions can be considered elliptical in shape, surgical removal is performed easily with an adapted croissant expander. We present a simple mathematical formula for calculating the exact dimensions of the required croissant expander. A good clinical result was obtained using this formula to design large custom-made croissant tissue expanders in a patient with a giant nevus.

The antecubital fasciocutaneous island flap for elbow coverage.

Soft-tissue defects in the area of the periolecranon may be a source of concern to the reconstructive surgeon who aims for durable protection with a minimum of drawbacks. Lamberty and Cormack described the antecubital fasciocutaneous flap both as a local transposition and as a free flap. The island version of this flap enables a single-stage transfer of thin, pliable, sensitive skin into the region of the periolecranon without further scarring around the defect. In general, most of the donor site can be closed primarily together with a small, full-sheet, split-thickness skin graft on the remaining skin defect on the volar surface of the distal forearm. An additional advantage of this flap is the rather straightforward dissection with minimal repercussion on the forearm contour. An anatomic overview as well as 4 patients are described to illustrate the appealing features of this fasciocutaneous flap.

Doppler flowmetry in the planning of perforator flaps.

Perforator flaps have become the first choice in free flap reconstruction of contour defects or skin and fat replacement in our department. The Deep Inferior Epigastric Perforator (DIEP), the Superior Gluteal Artery Perforator (S-GAP) and the Thoracodorsal Artery Perforator (TAP) flaps are now routinely used. By evaluating the vascular anatomy of these flaps preoperatively, we intend to improve our surgical strategy so that these operative procedures can proceed in a faster and safer way. In this study, the results of the colour Duplex scanning in 50 consecutive DIEP flap patients are reviewed and evaluated for their sensitivity and positive predictive value. Also the preoperative information from unidirectional Doppler flowmetry in 30 S-GAP flaps and 11 TAP flaps is evaluated for its reliability. Due to the variable vascular anatomy of the lower abdominal wall and the dorso-lateral thoracic wall we now prefer using the colour Duplex scanning for planning the DIEP and TAP flaps. The more constant course of the branches of the superior gluteal artery allows us to use the easier and cheaper unidirectional Doppler flowmetry for planning the S-GAP flap.

The fate of the oblique abdominal muscles after free TRAM flap surgery.

During recent years, clinical research on the donor site morbidity after free or pedicled transverse rectus abdominis myocutaneous (TRAM) flap surgery has been focusing on the reduced flexion capacity of the abdominal wall. However, the rectus abdominis muscles have close interactions with their synergists and antagonists and collaborate with their neighbouring muscles. The purpose of this study was to examine the consequences of partially resecting the rectus abdominis muscle on the different muscle groups of the abdominal wall. Twenty free TRAM flap patients, 12-61 months (mean 32.1 months) after surgery, were clinically examined, evaluated for curl-up performance and underwent isokinetic dynamometry for flexion, extension and rotation. The patients were compared with 20 non-operated controls. Nineteen patients answered a questionnaire. Abdominal wall abnormalities occurred in 10 patients: umbilical asymmetry (n = 3), abdominal wall asymmetry (n = 4), lower abdominal bulging (n = 2) and hernia (n = 1). Curl-up performance was less in the TRAM flap patients (P = 0.001, Mann-Whitney). Isokinetic flexion, extension and rotation were also less in the TRAM flap patients (Fisher's exact test). This study indicates that what has been believed to be 'limited' surgical damage to the abdominal wall leads to an important reduction in flexion strength but to an even more important reduction of rotation strength due to bilateral displacement and damage of the insertion of the oblique muscles. Partial compensation by synergists is variable and unpredictable on an individual basis. These functional disorders can potentially lead to important changes in activities of daily life.

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.

Free flap coverage of a gangrenous forefoot in a patient with Buerger's disease: a case report.

A patient with Buerger's disease is described in whom reconstruction of a gangrenous forefoot with a free flap has been successfully performed. In order to limit the amputation level, a more aggressive approach toward reconstruction in young patients seems appropriate. To our knowledge, this is the first described case of free flap reconstruction of a gangrenous defect in a Buerger patient.

Gluteal thigh flap used as a fascio-cutaneous free flap.

The gluteal thigh flap is a myofascio-cutaneous flap receiving its blood supply from a descending branch of the inferior gluteal artery. The gluteal thigh flap was first described by Hurwitz in 1980; since then numerous articles have reported on the successful use of this flap, as a transposition or a pedicled island flap, to cover wounds in the sacrogluteal and perineal regions. In contrast to its widespread use as a pedicled flap, employment of the gluteal thigh flap as a free flap is almost unreported in the literature, despite its extremely low donor morbidity and numerous articles on successful (other) free flap reconstructions based on the (same) inferior gluteal artery (e.g., in breast reconstruction). In this article we report on the successful use of the gluteal thigh flap as a purely fascio-cutaneous free flap in limb reconstruction. The literature on the microvascular anatomy of the gluteal thigh flap is reviewed in detail, and a precise description is given of the preoperative measures and surgical manoeuvres required to increase the reliability of this free flap. From the anatomical data and the problems encountered in this case, it should be concluded that, despite the many advantages of this flap and an ultimately successful outcome, the gluteal thigh flap is not a first choice flap for microvascular transfer.

Revascularisation by ingrowth of a free flap: fact or fiction?

Revascularisation of a critically ischaemic extremity by means of a free flap occurs through the development of vascular connections at the free flap-surrounding tissue interface. Three clinical cases are presented showing that in the particular situation of free tissue reconstruction of an ischaemic limb, vascular connections develop which are able at least partially to supply the free flap after occlusion of its arterial pedicle. One other case demonstrates similar vascular connections by angiography.

A universal incision for tissue expander insertion.

A new type of V- or W-shaped intralesional incision for tissue expander insertion is presented. The experience with 50 of these incisions in 36 consecutive patients in the period 1990-93 without any complication has proved the safety of this approach and the advantages of V- or W-shaped incisions over tangential or radial incisions.

Scar-length reduction by ring-shaped expansion.

Conventional tissue expansion with rectangular or round expanders often results in considerable dog-ear formation and, after resection, in lengthening of the final scar. The resulting scar is, always much longer than the maximal diameter of the skin lesion. These disadvantages are partially avoided by the use of croissant-shaped expanders. Taking the idea of the croissant-shaped expander and thinking further in terms of differential expansion, a new expander has been designed. It consists of a ring-shaped expander that is placed under the normal skin around the lesion. When the appropriate expansion is reached, the skin lesion is excised and the defect is closed with a running subcuticular suture, pulling as much skin as possible centripetally. The resulting scar is shorter than the maximal diameter of the skin lesion. The new expander has been tested in two patients in regions that are reputed for poor scar quality (the back and the upper arm). The results are encouraging.

Chylothorax after blunt chest trauma.

An unusual patient with chylothorax following blunt chest trauma is presented. Diagnosis was, in this acute case, clear after thoracostomy. In our patient conservative therapy with total parenteral nutrition failed and he was cured with a surgical closure of the duct leak. Chylothorax can be the cause of important morbidity and mortality, and straightforward diagnosis and therapy are mandatory.

[Treatment of aortic coarctation]. / Le traitement de la coarctation de l'aorte.

244 cases of coarctation of the aorta were treated surgically from 1953 to 1988. The age of the patients ranged from 3 days to 59 years with an average of 11.2 years. The average age of the patients decreased progressively over the years. 22% of the patients (54 patients) were less than one year old at the time of the operation. The percentage of infants presenting with decompensation and associated cardiac malformation increased progressively over the years. A total of 40 out of 54 patients belong to this group. The surgical procedure--resection and shunt--was a standard one in 89% of all cases. A prosthesis was required in 4.5% of all cases, and a widening patch in another 5.3%. An unusual technique had to be used in 1.7% of cases. The surgical mortality was of 12 patients (4.9%), all belonging to the infant group (3 days to 13 months old). No mortality was observed among older patients, nor among the elective surgical cases. 9 patients were treated for recurrence of coarctation. No case of paraplegia was noted in this series.
