Immediate full-thickness facial defects reconstruction using the radial forearm free flap

Summary The restoration of composite tissue defects of the oral cavity involving skin and mucosa remains a difficult problem for reconstructive surgeons. A method for immediate one-stage reconstruction of combined intraoral and facial defects with the radial forearm free flap is described. Four patients operated on between July and December of 1991 for advanced squamous cell carcinoma of oral cavity involving oral mucosa, skin and in two cases the mandible were reconstructed with a radial forearm flap to obtain reconstruction of facial and intraoral mucosa. The area of the fold is deepithelialized to be sutured to adjacent tissue.     

Suitability of the anterolateral thigh perforator flap and the soleus perforator flap for intraoral reconstruction: a retrospective study

Perforator flaps are suitable for numerous reconstructive purposes. However, there are few data about their usefulness for intraoral reconstruction. We reviewed data of 101 patients who were reconstructed by two types of perforator flaps after oral cancer. Forty-six soleus perforator flaps and fifty-five anterolateral thigh (ALT) perforator flaps were performed. Procedural data and outcome measures were analyzed. One ALT and four soleus perforator flaps were lost, resulting in success rates of 97.8% and 91.4%, respectively. Soleus perforator flaps were more challenging due to short and small-caliber vessels, higher susceptibility to vascular spasm, and difficult prediction of the location of the vascular pedicle. All donor sites in both groups except one were closed directly, and their morbidity was negligible. Perforator flaps from both donor sites can be used for intraoral reconstruction with good functional results; however, despite primary thinning, the ALT flap can be voluminous in small and flat defects. Here, soleus perforator flaps adapt better to the oral mucosa. The ALT perforator flap is more reliable and serves as a safe alternative to the radial forearm flap.     

Anterolateral thigh flap: ideal free flap choice for lower extremity soft-tissue reconstruction

This article presents the authors' experience with the anterolateral thigh free flap for lower extremity reconstruction. Twenty-one consecutive anterolateral thigh flaps were transferred for reconstruction of soft-tissue defects of the lower extremity from March 2000 to May 2002. Total flap survival was 90.5 percent, with two partial failures. Venous congestion was observed in one flap (4.7 percent) and the venous anastomosis was revised immediately in the postoperative second hour. The mean follow-up time was 13.4 months (range: 5 to 26 months). The cutaneous perforators were consistently found and presented as musculocutaneous in 19 patients (90.5 percent) or septocutaneous in two other patients (9.5 percent). A thinned anterolateral thigh flap was used in 11 patients. Sensate flaps were used in four patients (19.05 percent) for the reconstruction of amputation stumps. Five flaps (23.8 percent) were used also as flow-through flaps. All patients were satisfied with the cosmetic and functional results. The anterolateral thigh flap has many advantages over other free flap donors in lower extremity reconstruction. These include a long and large caliber vascular pedicle, large and pliable skin paddle, good color and texture matching, and minimal donor-site morbidity. Moreover, the flap can be used successfully and safely as a sensate, thin, or flow-through flap. The anterolateral thigh flap can be accepted as an ideal free flap choice for lower extremity reconstruction because it has maximal reconstructive capacity and produces minimal donor-site morbidity.

Intraoral reconstruction with “thinned” peroneal artery perforator flaps: An alternative to classic donor areas in comorbid patients

Free fasciocutaneous flaps like the radial forearm free flap (RFFF) and the anterolateral thigh (ALT) are the most commonly used flaps in intraoral reconstruction. However, certain conditions preclude the use of either of these flaps. The aim of this report was to show applicability of “thinned” peroneal artery perforator (PAP) flaps in intraoral reconstruction. We report two cases of squamous cell carcinoma involving the tongue and floor of the mouth, where one patient had advanced scleroderma with tight forearm skin and the other with a history of Reynaud's disease precluding the use of RFFF. In addition, both patients were morbidly obese with thick adipose tissue in the thigh making ALT flap not a suitable option. Instead, a PAP flap was chosen. After the harvest, the subcutaneous tissue thickness was measured to be 2.2 and 1.8 cm, respectively. The thinning was performed by removing the deep fat lobules of the superficial fat layer down to a final thickness of 0.4 and 0.3 cm, respectively. A 2 × 2 cm area surrounding the perforators were kept untouched. Both patients had uneventful postoperative course with one patient having a small donor area dehiscence that healed with local wound care. The functional outcomes at 1 year were good. “Thinned” PAP flap is a unique and novel application that may be an alternative in intraoral reconstruction when primary choices are not available. © 2014 Wiley Periodicals, Inc.

Waveform-arranged multiple skin paddles: A novel design to reconstruct complex soft tissue defects of the extremities with a modified multi-lobed perforator flap

BackgroundMulti-lobed perforator flap was one of popular approaches for one-stage reconstruction of complex soft tissue defects because of its minimal donor-site morbidity. However, the area of skin island that can be harvested on the donor site is limited on the angiosome distribution, Moreover, large defects require more than the conventional skin island provided by a traditional multi-lobed perforator flap. For further extended skin paddles, this study presented a novel design of waveform-arranged skin paddles to elevated a modified multi-lobed perforator flap for the reconstruction of complex soft tissue defects in the extremities.MethodsFrom March of 2015 to March of 2020, fifteen patients underwent complex soft tissue defects reconstruction with waveform-arranged multi-lobed perforator flaps. According the size, shape and localization of the defects, two strategies were performed to design this modified multi-lobed flap.ResultsA total of fifteen waveform-arranged multi-lobed perforator flaps were successfully harvested to reconstruct complex soft tissue defects of the extremities. Among of them, Waveform–arranged dual skin paddles perforator flap were performed in eleven cases, and the waveform–arranged tripaddle perforator flaps were used in four cases. All the flaps survived and no flap related complication was observed postoperatively. The donor sites were closed directly in all cases. The mean follow-up time was 15.6 months. Most of the cases showed satisfactory contour.ConclusionThe waveform design of multi-lobed perforator flap was an alternative approach for reconstruction of complex soft tissue defects; it can maximize the harvested skin area of the donor site to provide extended skin island.     

The combined free partial vastus lateralis with anterolateral thigh perforator flap reconstruction of extensive composite defects.

Myocutaneous (MC) free flaps are useful for many reconstructive indications. Perforator flaps have become standard of care. The anterolateral thigh flap (ALT) donor site is popular. With the ALT flap varying sizes of vastus lateralis (VL) muscle can be harvested as a MC flap. The skin islands of these flaps have a great range of freedom when dissected on their perforator. It was hypothesised that the VL-ALT perforator flap would offer adequate tissue volume combining maximal freedom in planning with minimal donor site morbidity. From November 2001 to February 2003 a free partial VL with ALT perforator flap was used in 11 patients to reconstruct large defects. Indications for adding a muscular component were exposed bone, skull base, (artificial) dura, or osteosynthesis material, open sinuses, and lack of muscular bulk. Flaps were planned as standard ALT flaps, after which three types of dissection were performed: I. true MC flap; II. muscle flap with a skin island on one perforator, which could be rotated up to 180 degrees ; III. chimera skin perforator flap with muscle being harvested on a separate branch from the source vessel or on a side branch of the skin perforator. Mean skin size of the MC-ALT flaps was 131 cm2. Mean muscle part size of the MC-ALT flaps was 268 cm3. Muscular parts were custom designed for all defects. No total or partial flap failures were seen. Colour mismatch was seen in 6 of 8 patients, when skin was used in the facial area in this all white population. Excessive flap bulk was found in 8 of 11 patients at 6 weeks, however, only in 2 of 11 patients after 6 months. Patients were satisfied with the functional result (8 of 11 patients) as well as the cosmetic result of their reconstruction (7 of 11 patients). All less satisfied patients had received their flap for external facial skin reconstruction. Donor site morbidity was minimal. The combined free partial VL with ALT perforator flap proved valuable as a (chimera type) MC flap with maximal freedom of planning to meet specific reconstructive demands and minimal donor site morbidity.     

Bilateral anterolateral thigh flaps for large-volume breast reconstruction

Autologous tissue reconstruction of a large breast in patients who are not candidates for a TRAM flap is a difficult problem. We present a case report of the use of bilateral free anterolateral thigh (ALT) flaps for immediate reconstruction of a unilateral large breast in a patient who had a previous abdominoplasty. Use of ALT flaps allows two or three surgical teams to work simultaneously, does not require intraoperative patient repositioning, has minimal donor-site morbidity, and can provide ample malleable soft tissue for breast reconstruction. These are advantages compared to the use of gluteal donor sites. The disadvantages include more conspicuous donor-site scarring on the anterior thighs.     

Pedicled deep inferior epigastric perforator flap for lower abdominal defects and genital reconstructive surgery

The pedicled deep inferior epigastric perforator (DIEP) flap can be used successfully to reconstruct the lower abdominal, inguinal, and genital regions. This muscle-sparing technique offers many advantages, such as minimal donor-site morbidity, a wide arch of rotation, and more versatile flap design, and provides for easier reconstruction than free flaps. Four pedicled DIEP flap cases are described in this article. The flaps were used to reconstruct lower abdominal defects and groin defects and to perform a penile reconstruction. To the best of our knowledge, ours is the first report in the English literature to describe the use of a pedicled DIEP flap for penile reconstruction. The donor sites were closed directly, and morbidity in all cases was minimal.     

Penile reconstruction with bilateral superficial circumflex iliac artery perforator (SCIP) flaps

The free radial forearm flap is a very common material for penile reconstruction. Its major problems are donor-site morbidity with large depressive scar after skin grafting, urethral fistula due to insufficiency of suture line for the urethra, and need for microvascular anastomosis. A new method using combined bilateral island SCIP flaps for the urethra and penis is developed for gender identity disorder (GID) patients. The advantages of this method are minimal donor-site morbidity with a concealed donor scar, and possible one-stage reconstruction for a longer urethra of 22 cm in length without insufficiency, even for GID female-to-male patients. A disadvantage is poor sensory recovery.     

A new technique for one-stage total lower lip reconstruction: Achieving the perfect balance

BACKGROUND:

Reconstruction of extensive lower lip defects is difficult. The authors describe a new technique of one-stage total lower lip reconstruction, with the ultimate goal being achievement of the delicate balance between adequate mouth opening and competent mouth closure, with satisfactory aesthetic outcome.

METHODS:

The authors applied their new reconstructive technique in a patient with extensive lower lip defect following excision of squamous cell carcinoma. Bilateral inferiorly based nasolabial flaps were used for reconstruction of lower lip. For vermillion reconstruction, a bucket-handle mucomuscular flap from upper lip was designed primarily using the pars marginalis portion of orbicularis oris. Compared with previously described techniques, this procedure is unique with respect to the alignment of the nasolabial flaps in relation to one another. Furthermore, this technique of vermillion reconstruction is a one-stage procedure with minimal morbidity, enables preservation of the vascular pedicle and innervation and maintains the orientation of orbicularis oris, thus providing a competent oral sphincter. To the authors’ knowledge, this mucomuscular upper lip flap has not been described earlier and has definite advantages over the commonly used methods of vermillion reconstruction.

RESULTS:

The functional and aesthetic outcomes are satisfactory on follow-up, with normal lip movements and sensation, adequate mouth opening and oral competence, good colour and texture match with adjacent tissues, and excellent volume and quality of the vermillion. No subsequent corrective surgery is required.

CONCLUSIONS:

This technique is simple and achieves the main goals of total lower lip reconstruction in a single stage with minimal morbidity.     

Free anterolateral thigh flap in pediatric patients

The anterolateral thigh (ALT) flap represents a workhorse flap in reconstructive surgery. We describe our clinical experience with this flap in the pediatric population. A total of 20 patients with an average age of 9.5 years underwent a free ALT flap reconstruction. All flaps were commonly raised on 2 perforators. About 5 flaps were employed for head and neck reconstruction, 7 for upper and 8 for lower limb reconstruction. Traumatic defects and congenital malformations represented the predominant etiology. Sizable perforators were found in all patients. The caliber was smaller compared to adults, and the course of the perforator was shorter. There were no complete flap losses and no significant donor-site morbidity. Donor-site closure required closure with split-thickness skin grafts in 6 cases. Hypertrophic scars developed in 4 patients. Secondary procedures included flap debulking (5) and Z-plasties (2). In conclusion, children have well-developed perforators supplying the ALT flap. With proper technique, this flap can be harvested and employed safely and reliably for reconstruction of varied defects in children.     

Mucosal prelamination of a radial forearm flap for intraoral reconstruction

Until now the microvascular fasciocutaneous radial forearm flap has been one of several methods favoured for reconstruction of intraoral soft tissue defects after radical resection of squamous cell carcinoma. Mucosal reconstruction and lining has been performed by a skin island, this is epidermis and cannot produce mucus. In order to provide mucosal properties and allow mucus production, a distal radial forarm flap has been successfully prelaminated with buccal mucosa in five patients. By this method thin, pliable and resistant flaps have been produced. Due to mucosal spreading, the mucosa lined area was 30–50% larger than the originally inserted mucosal grafts. Preservation of skin and subcutaneous tisssue lowered donor site morbidity. This technique has also been performed in axial pattern flaps; two osteofasciomucosal fibulae and three myomucosal pectoralis major flaps. Received: 17 July 1997 / Accepted: 15 October 1997     

Lateral arm free flap for oral tongue reconstruction: an analysis of surgical details, morbidity, and functional and aesthetic outcome

The purpose of this study was to report the effectiveness of the lateral arm free flap (LAFF) in the reconstruction of oral tongue defects, the subsite in which it may have advantage over the other donor sites. This is a retrospective analysis of 48 consecutive cases of LAFF used for the reconstruction of partial glossectomy defects for squamous cell carcinoma of the oral tongue. Primary defect and donor-site morbidity and the functional and aesthetic outcomes were assessed in 37 evaluable patients, with a minimum of 6 months follow-up. Patient-reported Visual Analog Scale score from 0 (minimum satisfaction) to 10 (maximum satisfaction) was used to evaluate the aesthetic outcome. The follow-up was for 6 to 52 months (mean, 24 months). The flap was successful in 45 (93.8%) patients. The commonest observed donor-site morbidity was a broad scar, but it did not cause much patient dissatisfaction because it could be covered with appropriate dressing. Speech was normal or near-normal in all patients. Poor functional outcome was associated with adjuvant postoperative radiotherapy. The visual analog scale score for the aesthetic satisfaction (mean [standard deviation]) was 6.58 (1.82) for primary site and 7.13 (1.99) for the donor site. LAFF is an excellent option for the reconstruction of partial glossectomy defects of oral tongue without significant involvement of the floor of mouth and base of tongue.     

Reconstruction of trunk defects with bilobed myocutaneous flap.

This study describes the use of the bilobed myocutaneous (MC) flap for reconstruction of trunk defect. The authors employ this flap because it offers a greater flexibility in the use of available tissue than many other local conventional flaps, is easy to design, safe to elevate, and causes minimal donor-site morbidity. The bilobed MC flaps are based on their main muscular pedicle. The standard bilobed flaps are generally based on a random pattern blood supply, which were restricted to rigid length-to-width ratios to ensure viability. They are usually indicated in the repair of small defects of the nose, and scalp. When we want to apply to reconstruct on the larger trunk defect, especially for the potential to cause life-threatening complications, the bilobed M-C flap might be considered for reconstruction to decrease the potential risk of the complications.     

Donor-Site Complications in Vascularized Bone Flap Surgery

Microvascular osteocutaneous free flaps have given reconstructive surgeons a powerful tool in the reconstruction of composite defects in head and neck surgery. Radial forearm, scapula, iliac crest, and fibula flaps have been used extensively in mandibular reconstruction. The inevitable donor-site morbidity of these osteocutaneous flaps has received less attention than the reconstructive advantages. We have reviewed the literature for each type of flap to determine the kind, incidence, and consequences of flap associated morbidity. In the future, tissue-engineered prefabricated free flaps might play an important role.

Pedicled deep inferior epigastric perforator flap: an alternative method to repair groin and scrotal defects

With minimal donor-site morbidity and bulky soft tissue supply, deep inferior epigastric perforator (DIEP) flap is now a preferred free flap in reconstructive surgery. Based on the experiences in free flap procedures, the authors explored a new usage of the DIEP flap to repair groin and scrotal defects. Over the last 2 years, 8 pedicled DIEP island flaps were successfully elevated and transferred in 7 male patients. With intramuscular dissection, the pedicle length could be elongated, with minimal damage to the abdominal fascia-muscular structure. Among these flaps, 5 were used for penoscrotal restore; 3 were raised to repair groin defects. All flaps survived completely. Groin reconstruction with such a flap gave a satisfactory esthetic result. Though somewhat bulky for penoscrotal restoration, it was acceptable for elderly patients. The authors conclude that this flap can be chosen as an alternative option to deal with complex groin and scrotal wounds.
