Shape-modified radial forearm free tissue transfer in oral cavity reconstruction: Technique and a prospective comparison with the conventional technique

Dovetailing skin incision design of radial forearm free flap for forearm wound closure and maxillofacial reconstruction

Object

This study aimed to examine the feasibility of the dovetailing skin incision design of radial forearm free flap (RFFF) for closing forearm wounds and performing maxillofacial reconstruction.

Method

A total of 27 patients were divided into two groups. In the dovetail group (n = 16), forearm wounds were closed primarily and maxillofacial defects were reconstructed by dovetail RFFF. In the conventional group (n = 11), forearm wounds were closed by skin grafts from the abdomen or mattress suturing, and maxillofacial defects were reconstructed by conventional RFFF. Information on the healing time of the forearm wound, length of postsurgical hospitalization, esthetic assessments, and complications associated with the forearm wound and the maxillofacial region was collected at least 6 months postoperatively.

Result

The average size of the flap in the dovetail group was smaller than that in the conventional group (p = 0.134), and average healing time of the forearm wound in dovetail group was significantly shorter than that in conventional group (p = 0.000). Comparing with the conventional group, there were more cases in the dovetail group demonstrating decreased sensitivity (p = 1.000). Esthetic assessments of forearm wound and maxillofacial reconstructions in the dovetail group were significantly higher than that in the conventional group (p = 0.000).

Conclusion

Closure of forearm wounds and maxillofacial defects using dovetail design was found to be a feasible alternative to the conventional design.

Radially Pedicled In-Situ Split-Thickness Skin Grafts, an Alternative to Distal Split-Thickness Skin Grafts

OBJECTIVE

This study aimed to introduce a novel radially pedicled in-situ split-thickness skin graft (STSG). The morbidity, esthetic, and functional outcomes of the radially pedicled in-situ STSG were in comparison with those of the distal STSG.

STUDY DESIGN

Retrospective analysis.

SETTING

A single-institution review.

METHODS

Seventy patients with oral cancer who underwent radical surgical resection and simultaneous radial forearm free flap (RFFF) reconstruction from July 2021 to March 2022 were included. De-epithelialized RFFFs and traditional RFFFs were used to repair oral defects of 35 patients in Group A and Group B, respectively, while radially pedicled in-situ STSGs and distal STSGs taken from abdomens were used to repair donor site defects in the above groups, respectively. Patient demographics, wound healing complications, and esthetic and functional outcomes of the forearms were compared between the 2 groups.

RESULTS

No significant difference between Group A and Group B was observed in terms of donor site and recipient site complications. The esthetic outcome was superior in Group A compared to Group B (P = .011). The extension range, sensation, and pinch strength of operated forearms were significantly reduced in both groups after surgery (P < .05), however, intergroup differences were not observed.

CONCLUSION

Taken together, our results suggest that radially pedicled in-situ STSG is an applicable technique for direct closure and better esthetic outcomes in the forearm donor site.

Survival of Dental Implants Placed in Iliac, Fibula, and Radial Forearm Flaps: A Comprehensive Review

Various donor sites have been extensively documented in the literature for bone free flaps in head and neck reconstruction. These include the radius, scapula, rib, ilium, femur, fibula, and metatarsal bone. Among them, the fibula, ilium, and scapula are the most commonly used and studied for placing endosseous implants and for rehabilitation purposes. Each donor site has its own advantages and disadvantages, which depend on factors such as whether the reconstruction is for the maxilla or mandible, the required volume and length of the bone and soft tissue, and the location, extent, and type of defect that needs to be reconstructed. The aim of this current review is to comprehensively assess the existing literature on the survival of implants in fibula, radial, and iliac flaps.

Shape-modified radial forearm flap: does it still have a role in upper extremity reconstruction?

OBJECTIVES

To carry out a radial forearm flap, the radial artery is usually harvested, incurring severe donor site morbidity. Advances in anatomical knowledge discovered constant radial artery perforating vessels, enabling the subdivision of the flap into smaller components suitable for a wide range of differently shaped recipient sites, with marked reduction of downsides.

MATERIAL AND METHODS

Eight pedicled or free shape-modified radial forearm flaps were used to reconstruct upper extremity defects between 2014 and 2018. Surgical technique and prognosis were examined. Skin texture and scar quality were assessed on the Vancouver Scar Scale while function and symptoms on the Disabilities of the Arm, Shoulder and Hand score.

RESULTS

At a mean follow-up of 39 months, no cases of flap necrosis, impaired hand circulation or cold intolerance were found.

CONCLUSION

The shape-modified radial forearm flap is not a new technique, but is poorly known by hand surgeons; in contrast, our experience showed it to be reliable, with acceptable functional and esthetic outcomes in selected cases.

Radial Forearm Free Flap for Head and Neck Defect Reconstruction: An Up-to-date Review of the Literature

The radial forearm free flap has emerged as the mainstay of free flaps for oral cavity soft tissue reconstructions because of its versatility and ability to be used in the reconstruction of large and medium-sized defects. This flap is commonly used to restore head and neck defects, including full-thickness lip and oral cavity defects. This flap offers the opportunity to cover severe defects of the facial region due to its long vascular pedicle and elasticity. In addition to its ease of being harvested, the radial forearm free flap provides a sensate, pliable, and thin skin paddle with a long vascular pedicle. However, it can cause severe morbidity at the donor site, mainly due to exposure of the flexor tendon that results from a failed harvesting of the skin graft, changed sensation in the radial nerve, aesthetic deformity, and reduced range of motion and grip strength. This article aims to review all the up-to-date studies discussing the use of radial forearm free flap in head and neck reconstruction.

Radial forearm free flap in a patient with an unusual radial artery variation: a case report

Head and neck reconstruction poses unique challenges in rehabilitating surgical defects in terms of integrity, function, and form. The radial forearm free flap (RFFF) has been widely used for defect coverage, especially in the head and neck area, but its versatility allows it to be used for soft-tissue reconstruction in various parts of the body. The vascular features of the flap are quite constant and reliable. Nevertheless, abnormalities of the forearm vascular tree have been described over the decades. We report a case of intraoral reconstruction after verrucous carcinoma recurrence in a 74-year-old woman with an unusual forearm flap, which we called the median forearm free flap, based on a median branch of the radial artery that was preoperatively detected using handheld Doppler ultrasonography. The distally located skin paddle was predominantly supplied by the aberrant median vessel with its perforators. The flap was thus safely harvested with this atypical pedicle. Successful reconstruction of the intraoral defect was achieved, with an uneventful postoperative course.
