A buried reversed radial forearm flap in pharyngeal reconstruction: refinements and monitoring

Pharyngeal reconstruction can be accomplished in a variety of ways, from pedicled to free revascularized tissue transfers. The use of an extra skin paddle combined with a buried radial forearm flap, which permits long-term postoperative monitoring under direct vision, has been described before. In this study, we monitored nine patients who had undergone pharyngeal reconstruction with a buried reversed radial forearm flap. Our modified technique gave better coverage of the large vessels and a better postoperative neck contour, prevented esophageal leakage and facilitated continuous postoperative patient monitoring, without any significant additional donor site morbidity.

Donor site morbidity of the prelaminated fasciomucosal and fasciocutaneous radial forearm flap: a comparative study

In order to reconstruct intraoral lining defects after radical tumor resection, mucosal prelamination of the fascia of the distal radial forearm flap was performed in ten patients. By this method a physiologic reconstruction with mucus-producing tissue could be achieved. Preservation of skin and subcutaneous tissue enabled primary closure of the donor site. The exposed median nerve and flexor tendons could be covered by well-vascularized tissue with, hopefully, less donor site morbidity. To investigate this, eight prelamination patients were compared to five patients in whom conventional fasciocutaneous distal radial forearm flaps were harvested. Follow-up was 6–25 months (mean 12.8 months). All patients with prelaminated forearm flaps revealed excellent functional and cosmetic results. Restricted hand function and a poor cosmetic result were found in 40% of the fasciocutaneous flap patients. Subjective cold intolerance could be objectified using thermography, but could not be confirmed, using rheography and photoplethysmography. Received: 9 March 1998 / Accepted: 16 November 1998     

Venous flow-through flap as an external monitor for buried radial forearm free flap in head and neck reconstruction.

Postoperative monitoring of buried free flaps in head and neck reconstruction can be extremely difficult or impossible. The authors describe a series of 11 cases over a 21-month period, of buried radial forearm free flaps used in head and neck reconstruction. To monitor the main buried flap a small venous flow-through flap is supplied by and attached to the cephalic vein of a radial forearm free flap. This small venous skin flap is inset separately from the main paddle, so that it is visible at the external surface of the neck, furnishing information about the perfusion of the entire flap.     

The free radial forearm flap for reconstruction of facial defects in noma patients

Within a 2-year period ten patients aged 5–22 years were treated for facial sequelae of noma. In six cases free radial forearm flaps were used, combined with local and regional flaps. The indications were defects located in the midface and perioral area. There were no free or regional flap losses in this series. The aesthetic and functional results were appreciated by the patients and there were no functional problems related to the donor area because a suprafascial flap dissection technique was used. In our experience the free radial forearm flap is a valuable option for facial reconstruction in NOMA cases. The advantages include: (1) A very long and large calibre pedicle; (2) thin and pliable flaps of variable size and configuration; (3) the possibility of single stage reconstruction in selected cases. The disadvantages include the not always ideal colour match, both in black patients and in white, and the unsightly donor area which, however, has never led to functional problems.

The radial forearm flap without fascia and other refinements

The radial forearm flap is generally classified as a fasciocutaneous flap. The skin of the forearm is, however, supplied by branches from the radial artery which pierce the fascia of the forearm to course and branch subcutaneously. We have used the flap as a skin flap in 300 cases over 11 years. It is not necessary to take the fascia with the flap. Two other refinements of the forearm flap, also used over the past 11 years, are described. The venous drainage of the flap is simplified by utilising the usual anatomical confluence of deep and superficial veins at the elbow. Secondly, draping a large loop of pedicle in the neck during intraoral reconstruction enables a larger calibre vein to be used for the anastomosis, thus increasing its reliability.     

Head and neck reconstruction: a review of 117 cases

The reconstruction of defects of the head and neck, no matter the cause, begins with a careful assessment of the patient and the defect. Ideally, it ends with the successful execution of the reconstructive procedure that optimally restores form and function with minimal morbidity. There are several treatment possibilities that differ in their indications, technical difficulty, safety, and incidence of complications. This is a review over a period of 13 years of 117 cases of head and neck reconstruction performed by the author. Sixty-eight patients were treated with five different musculocutaneous pedicled flaps, mainly during the first half of the 13-year period. Those based on the pectoral major and latissimus dorsi were the most frequently utilized, mainly in pharyngolaryngeal reconstructions and sometimes as osteomyocutaneous flaps for oromandibular defects. Forty-nine patients had microvascular reconstructive procedures with 12 different types of free flaps. The latissimus dorsi flap was used for reconstruction of the scalp and after excision of intracranial lesions, whereas the serratus anterior or rectus abdominis free flaps were utilized for reconstruction of complex defects of the middle-third of the face. The radial forearm flap and the free jejunum have become the choice for intraoral and pharyngoesophageal reconstruction, respectively. Good results were obtained in both functional and social rehabilitation of the patients. There were three flap losses due to thrombosis of the microvascular anastomosis. There was no surgical mortality. The indications for each pedicled and free flap are discussed. Received: 27 October 1999 / Accepted: 22 June 2000     

Free composite osseomyocutaneous flap of latissimus dorsi, serratus anterior and rib for oromandibular reconstruction

A wide variety of osseomyocutaneous free flaps for mandibular reconstruction has been described. The flap made up of latissimus dorsi, serratus anterior and rib (LSRF), , can provide vascularized skin, muscle, bone and cartilage on a single thoracodorsal vascular pedicle and is useful in some circumstances, i.e., large soft tissues defects. In this paper, we describe two cases in which the flap was chosen for reconstruction of the mandible, cheek and intraoral mucosa, following major ablation of malignant tumours. In our experience, this flap is excellent for soft tissue repair and fulfils the basic requirements of bony restoration. Moreover, the donor site morbidity is minimal and its dissection is rather easy. The LSRF may be the first choice in certain reconstructive circumstances.

Neophalloplasty using a rectus abdominis muscle flap and a radial forearm free flap

Summary A method for construction of a neopenis in female-to-male transsexual patients is described. The method consisted of inferior transposition of a rectus abdominis island muscle flap with resurfacing using a radial forearm free flap. Excellent internal support and a natural looking appearance was achieved. This technique was considered to be better than any other previously used method of neophalloplasty.     

The indications and outcomes in the use of osteocutaneous radial forearm free flap

INTRODUCTION: Whether secondary to cancer surgery ablation or trauma, surgeons are faced with defects of the mandible or maxilla that would be best reconstructed with a thin, pliable soft tissue component and vascularized bone. A subset of these challenging wounds do not require the bicortical bone necessary to reestablish structural integrity or to retain a dental prosthesis, because the soft tissue needs are more critical than the bony needs. It is this niche that the radial forearm osteofaciocutaneous free flap (RFOFF) fulfills well. In the past, potential and real donor site morbidity has precluded the routine use of this flap. New methods to reduce this morbidity have rekindled our use of this flap. PROCEDURES USED: A retrospective review of patients with defects of the mandible or maxilla treated with the RFOFF from July 1, 1997, to December 31, 2000, was performed. After flap harvest, the donor site was rigidly fixated. A skin graft was placed, and a volar splint was applied for 7 days. The arm was then fully mobilized. Parameters examined were defect location, donor site complications, flap survival, fistula occurrence, plate fracture, and/or extrusion. RESULTS: Thirty-four patients were reconstructed with the RFOFF with a follow-up of 10-54 months. Seven patients had an anterior maxillectomy defect, and 27 patients had a lateral mandibulectomy defect with associated tongue/tonsillar fossa and/or palate defect. There were no cases of flap failure or donor site radius fracture. During the follow-up period, there were no plate fractures or intraoral exposures as evidenced by clinical and radiographic evaluation. Fistulas occurred in five patients; all healed without surgical intervention. CONCLUSION: With rigid fixation of the residual radius, donor site morbidity has been minimized, and indications for this flap have expanded. Specifically the anterior maxillary arch and the ascending ramus, angle, and posterior body of the mandible (nontooth-bearing areas) are the sites most amenable to the thin bony stock of the harvested radius. The pliable forearm skin is ideal for the soft tissue defects. We believe that the RFOFF with bone has a definite role in the reconstruction of select head and neck defects.     

Island orbicularis oculis myocutaneous flap from the upper eyelid for lower eyelid reconstruction

An island myocutaneous flap of orbicularis oculis for reconstruction of central lower eyelid defects is presented. This flap is able to cover anterior lamellar defects extending up to 2/3 of the lower eyelid. It is also suitable for full thickness defects when the posterior lamellar involvement is less than 1/3 and can be closed primarily. In our hands this flap proved to be a good alternative to the classic reconstructive methods for the lower eyelid, since in one operation it offers the same skin quality, exactly fitting the defect, with a low complication rate. This reconstructive method for lower eyelid defects is safe, relatively simple and provides good functional and aesthetic results. Received: 21 August 1996 / Accepted: 15 June 1997     

Donor site morbidity of free jejunal flap reconstruction of the oropharyngeal cavity

The study was performed to evaluate abdominal complications related to jejunal segment resection for reconstruction after radical oropharyngeal tumor resection. Perioperative complications of 104 patients (median age, 53.7 years; 23 female; 81 male) who underwent surgery for oropharyngeal malignancy after radiochemotherapy and the long-term morbidity of 35 patients after a median follow-up period of 21 months are analyzed. The perioperative mortality was 8.7% (9/104); none of the perioperative deaths was caused by an abdominal complication associated with the jejunal resection. In three cases, repeat laparotomy was performed within 30 days of jejunal autotransplantation: in two of them the reason was not directly associated with bowel resection and one patient had an abdominal wall dehiscence. In six cases there were minor abdominal complications which could be treated nonsurgically. There was no anastomotic leakage, bowel obstruction or postoperative bleeding. In the follow-up re-examination, no late onset abdominal complications were noted except small incisional hernias in six of the 35 patients; only one required a hernia repair. Despite a potentially increased operative risk in these patients, the complication rate after bowel resection for jejunal autotransplantation was low. This is a safe procedure in patients with oropharyngeal carcinoma. Received: 9 March 1998 / Accepted: 14 December 1998     

Reverse osseofasciocutaneous radial forearm flap for thumb reconstruction: a flap design and case series

PURPOSE: To report the outcome of the modified design of the osseofasciocutaneous radial forearm flap. The flap was modified because of problems associated with the use in thumb reconstruction. METHODS: We performed retrospective review of all patients who sustained nonreplantable thumb amputations who had this procedure between August 2000 and March 2005. The patients' ages ranged between 24 and 39 years. Demographic data and details of the level of amputation and alternative surgical procedures were reviewed. Eight male patients were identified and constituted the study cohort. The size of flap, length of the radius harvested, time to union, sensibility (moving 2-point discrimination test), grip and pinch strengths, complications, and patient outcome were determined. RESULTS: All patients who had the butterfly design of the reverse-flow osseofasciocutaneous radial forearm flap had an adequate and painless soft-tissue padding on the tip of the reconstructed thumb that provided good protection for the distal stump of the vascularized bone graft. Patients did not experience strictures at the bottom of the reconstructed tubes. CONCLUSIONS: The butterfly design is a useful modification of the skin paddle of the reverse osseofasciocutaneous radial forearm flap for thumb reconstruction. The design offers an easy way to reconstruct a tube shape with adequate padding on the tip and no terminal scar. In addition it prevents the constricting effect of the circumferential scar on the button of the reconstructed tube.     

Free radial forearm adiposo-fascial flap for inferior maxillectomy defect reconstruction

A free radial forearm fascial flap has been described for intraoral reconstruction. Adiposo-fascial flap harvesting involves few technical modifications from the conventional radial forearm fascio-cutaneous free flap harvesting. We report a case of inferior maxillectomy defect reconstruction in a 42-year-old male with a free radial forearm adiposo-fascial flap with good aesthetic and functional outcome with minimal primary and donor site morbidity. The technique of raising the flap and closing the donor site needs to be meticulous in order to achieve good cosmetic and functional outcome.     

Tensor Facia Lata-iliac crest osteocutaneous flap for orbitomaxillary reconstruction: A preliminary report

Tensor Fascia Lata muscle and musculocutaneous flap has been used in the past for reconstruction of trunk defects and also as a free flap for soft tissue reconstruction elsewhere in the body. Transferring the iliac crest along with the muscle as a free flap has been described earlier, reported for bridging calcaneal defect and small mandibular defects. The use of this flap as a source of free vascularised bone has not been widely practised since these initial few reports. Anatomical studies were carried out to assess the feasibility of using this flap for reconstructing maxillary and other head and neck defects, following which it was successfully used for these indications. The preliminary report describes the flap anatomy, method of harvest and its potential uses in head and neck reconstruction.
