Repair of pharyngocutaneous fistulas with the submental artery island flap

Pharyngocutaneous fistulas after total laryngectomy are difficult to manage and are a cause for significant morbidity to the patient. When fistulas fail to close with conservative measures, debridement and flap closure are indicated. Although a number of techniques to repair pharyngocutaneous fistulas are described, each of these procedures has its drawbacks. The authors have used the submental island flap to close postoperative pharyngocutaneous fistulas in nine male patients during the past 4 years. The mean patient age was 65 years (range, 57 to 75 years). The submental island flap is based on the submental artery, a branch of the facial artery. The inner aspect of the fistula was initially formed using hinge flaps on the skin around the fistula. Once a watertight closure of inner side was created, the skin defect was closed with the submental island flap. The maximum flap size was 6 x 3 cm and the minimum size was 4 x 2 cm (average, 4.8 x 2.7 cm) in this series. Direct closure was achieved at all donor sites. Patients were followed for 6 months to 4 years. No major complication was noted in the postoperative period. All patients have successfully recovered their swallowing function. The submental island flap is safe, rapid, and simple to elevate and leaves minimal donor-site morbidity. The authors believe that this technique is a good alternative in the reconstruction of pharyngocutaneous fistulas. Application of the technique and results are discussed.     

Hair-bearing neck flap for upper-lip reconstruction in the male

Reconstruction of the upper lip resulting in a hair-bearing area and a non-hair-bearing lining is described in two cases of full-thickness lip defects. A unipedicled neck flap was used in one case and a bipedicled neck flap in the other, both comprised of hair-bearing and adjacent non-hair-bearing areas. The neck flap has the advantages of providing the two layers of the lip, and the reconstructed lip is not too thick and is mobile and pliable, and the hair resembles lip hair in color, density, and quality. The multiple operative procedures can be performed under local anesthetic.     

Oropharyngeal reconstruction using the supraclavicular artery island flap: a new flap alternative

Oropharyngeal reconstruction following head and neck oncologic resection has utilized local, regional, and free tissue transfer flap options. The modality utilized is often guided by the type of defect created as well as the surgeon's preference. In this article, the authors introduce the application of the supraclavicular artery island flap as a reconstructive modality following oropharyngeal oncologic ablation. Five patients underwent head and neck oncologic resection for oropharyngeal squamous cell carcinoma followed by single-stage reconstruction with an ipsilateral supraclavicular artery island flap. There were no flap failures and only one postoperative complication consisting of a postoperative oral-cutaneous fistula that resolved without surgical intervention. There were no donor-site complications. The supraclavicular artery island flap is a viable alternative for oropharyngeal reconstruction following head and neck oncologic resection. It is a regional flap that can be harvested without microsurgical expertise and yields reliable postoperative results. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.     

Retroauricular island flap for eye socket reconstruction

This paper describes the use of a flap which is the random portion of an island flap based on superficial temporal vessels. The flap has three distinct anatomic portions: the cutaneous portion, which includes the postauricular skin, the triangular deepithelialized scalp and fascia above the ear, which augments random-pattern blood circulation to the cutaneous portion, and the superficial temporal fascia encompassing the vascular pedicle, which is dissected down to the upper pole of the parotid gland and unfolded using a cutback incision between the vascular pedicle and the second portion of the flap in order to increase the reach of the cutaneous portion. The flap has been successfully used in eight patients for reconstruction of missing or contracted eye sockets. In two patients, inconsequential superficial loss of the distal portion of the distal flap was observed. This flap can also be used for reconstruction of the external face, eyelid, and palate as well as soft-tissue augmentation.     

Anatomic study of the vasculature of the submental artery flap

The submental artery island flap is a versatile option in head and neck reconstruction. This flap may be used for the coverage of perioral, intraoral, and other facial defects, leaving a relatively acceptable donor-site scar. In this study, the submental region of 13 formalin-fixed cadavers was dissected bilaterally. Comprehensive anatomical information regarding the pedicle of the flap and its relationship with the important adjacent structures is provided. The mean values of the measurements of the facial and submental arteries were as follows: the facial artery was 2.7 mm in diameter at the origin, and it crossed the mandibular border 26.6 mm from the mandibular angle. The origin of the submental artery was 27.5 mm from the origin of the facial artery, 5.0 mm from the mandibular border, and 23.8 mm from the mandibular angle. The diameter of the submental artery was 1.7 mm at the origin. The artery was found mostly to course superficial to the submandibular gland. In one case, the artery passed through the gland. The total length of the submental artery was 58.9 mm. The artery anastomosed with the contralateral artery in 92 percent of the cadavers. The submental artery was deep to the anterior belly of the digastric muscle in 81 percent of the cases. This study presents detailed anatomical data about the location, dimension, and relationship of the facial artery, the submental artery, and the submental vein that may be useful during dissection of the submental artery island flap.     

Breast reconstruction with the internal mammary artery pedicled fasciocutaneous island flap: description of a new flap

Postburn skin contracture of the inframammary sulcus is a commonly encountered problem, especially in pubescent girls. Release of these contractures is commonly performed by split-thickness skin grafts, which necessitate further operations as the child grows. If the contracture of the inframammary sulcus is only one-sided, then the inframammary tissues of the contralateral breast can be used for reconstruction with the fasciocutaneous island flap. The donor site can be closed primarily without disrupting the appearance of the healthy breast, and the skin incision is hidden in the inframammary sulcus. The flap described here is a fasciocutaneous island flap based on the internal mammary artery and the perforating branches to the skin and subcutaneous tissues that the artery gives off as it leaves the thoracic cavity through the seventh intercostal space. After being supported by fresh cadaver and angiographic studies, the flap was applied to seven female patients (four of whom were pubescent) with burn contracture of the breast; satisfactory results were obtained. In defects of the mammary region that required volume or for which repair by skin grafting was planned, in sternal defects, or in young patients, this flap seems to be the best choice.     

Breast reconstruction with a transverse abdominal island flap

A rectus abdominis musculocutaneous island flap for breast reconstruction following mastectomy is presented. The vascular anatomy of the abdominal wall has been clinically studied in patients undergoing abdominal lipectomy. Cadaver dissections are shown, demonstrating the anatomy, arc of rotation, and design alternatives of the rectus abdominis flap. The surgical technique is demonstrated and representative patients are shown.     

The L-shaped combined vertical and transverse abdominal island flap for breast reconstruction

The occasional patient will present for reconstruction after mastectomy who refuses a foreign-body implant or is desirous of reconstruction by autogenous tissue. An unfavorable midline abdominal scar that extends both below and above the umbilicus will preclude the use of the standard lower or upper transverse abdominal island flaps for such purposes. For these highly select circumstances, we present our experiences with two such patients where a combination of an L-shaped vertical and transverse rectus abdominis myocutaneous flap was employed. In this procedure, the vertical component is planned to provide the external skin cover, while the ipsilateral hemiellipse transverse component is deepithelialized and buried deep to the vertical component to provide the bulk and mound projection.
