Modified H-plasty in large basal cell carcinoma defect reconstruction on the forehead.

Basal cell carcinoma (BCC) is the most common malignancy worldwide. Surgical removal is considered the gold standard treatment. However, large defects following excisional surgery can pose a significant challenge for reconstruction, especially in cases where primary closure is not possible. In these cases, skin flaps may be used. Most traditional skin flaps are limited by design to take advantage of only one region of relative skin excess. This paper reports a case of a large forehead defect following BCC excision that was successfully reconstructed by a modified Hplasty involving a U-plasty and rotation-advancement flap. Maintenance of aesthetics without impaired function is the aim of closure defects with combined flaps.

Application of combined local flaps in repair of large nasal defects after cutaneous tumor excision / 中华医学美学美容杂志

Objective:To explore the experience to reconstruct large nasal defects with combined local flaps after cutaneous tumor excision based on the aesthetic subunit principle.Methods:From May 2007 to May 2019, based on the nasal aesthetic subunit principle, combined local flaps were used to cover the large nasal defects in 21 cases of nasal tumors that were removed. Among 21 cases, there were 11 cases of basal cell carcinoma, 7 cases of squamous cell carcinoma, and 3 cases of pigmented naevus. The locations were dorsum of nose in 8 cases, nasal side in 7 cases, nasal ala in 5 cases, nasal tip in 1 case, and across two nasal subunits in 17 cases. The area of the defect ranged between 1.3 cm × 0.9 cm and 3.6 cm × 3.1 cm. A local combined skin flap was used to repair the skin defect. The secondary defect of donor site was directly sutured.Results:Among 21 cases, 20 cases acquired complete recovery; 1 case had epiderm necrosis over the far end of the flap achieved healing by the first intention. The nasal defect was successfully repaired in all patients, and the all flaps survived. A total of 21 patients were available for follow-up of 1 to 48 months, no tumor recurrence occurred, and the repaired tissues were well matched to the surrounding tissue, good nasal contour was obtained, and the cosmetic results were satisfactory.Conclusions:Based on the nasal aesthetic subunit principle, the combined local flaps can be used to reconstruct the large nasal defects, and the cosmetic results are satisfactory.

Effect of hallux toe nail flap and adjacent island flap of the middle and ring fingers in repair of degloving injury of distal thumb / 中华显微外科杂志

Objective:To summarise the clinical efficacy and surgical indications for free hallux toe nail flap and adjacent island flap of the middle and ring fingers in repair of distal thumb degloving injuries.Methods:From May 2009 to May 2021, a total of 24 patients (24 digits) with degloving injury of distal thumbs were treated in the Department of Hand and Microsurgery of Baoji Third Hospital. The flap was selected according to the patient's wishes and occupation. Of the 24 patients, 13 were repaired by free hallux toe nail flap transfer (group of hallux toe nail flap), and 11 were repaired by combining the proper palmar digital artery island flap of middle (ulnar side) and ring (radial side) fingers with the same volar common digital artery vascular pedicle (group of tile combined flap). Follow-up was performed at the 1st, 3rd, 6th,12th and 18th months after surgery respectively through outpatient clinic and telephone or WeChat interviews. The follow-ups focused on the appearance, colour, texture and two-point discrimination (TPD) of the flap, as well as thumb flexion, extension, opposition and grasping functions. Functional recovery evaluated according to the Evaluation Standard of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association.Results:All the 24 flaps survived and all were included in the follow-up. The follow-up lasted 12-60 and 6-18 months, with an average of (18.5±0.5) months and (6.8±0.3) months in group of hallux toe nail flap and group of tile combined flap, respectively. Appearance of thumb body and function at the last follow-up showed: in the group of hallux toe nail flap, the nails, thumbtips and fine sensations were restored, with the TPD at 5-8 mm. The thumb flexion, extension, opposition and grasping functions were good. Apart from without nails and fingerprint, the flaps in the group of tile combined flap had good appearance and texture, and the protective feeling was restored with the TPD at 6-11 mm. The affected thumbs also recovered the basic functions of flexion, extension, opposition and grasping. According to the Trial Standard of Upper Limb Function Evaluation of the Chinese Medical Association Hand Surgery Society, 7 cases were excellent, 5 cases were good, and 1 case was poor in the group of hallux toe nail flap. In the group of tile combined flap, 3 cases were in excellent, 5 in good, and 3 in poor. Appearance of flaps (such as nails and thumbtip fingerprint), fine sensory recovery, and the accuracy and stability of the grasping function, the group of hallux toe nail flap was significantly better than that of the group of tile combined flap. There was no functional impact on the donor site.Conclusion:Both types of flap are classic surgical procedures for repair of distal thumb degloving injury. In order to meet the individual requirement and to improve the efficacy of the treatment, such as for those who have high expectation for digit restoration, especially those who are young with aesthetical or professional requirement, free hallux toe nail flap repair is used to restore the perfect shape and function. And for those who are reluctant to sacrifice their toes or for the middle-aged and elderly people who do not have high expectation for the shape of thumb, a tile combined flap repair is used to restore thumb function.

Reconstruction of Alar-Perialar Defects with a Combined Subcutaneous and Cutaneous Pedicled Rotation-Advancement Nasolabial Flap.

Aim of the Study: During the reconstruction of alar defects involving the upper lip, reconstructive surgeons face the need for various thicknesses of tissues crucial to preserving the facial sulcus which is important for a cosmetically acceptable result. Our aim was to reconstruct the deep perialar and thinner lateral nasal alar defect in a single step procedure with a suitable flap which is reliable, has appropriate blood supply and provides an esthetically good result. Materials and Methods: Extended alar defect was reconstructed with a combined flap in 10 cases. During the procedure, a subcutaneous pedicle was created and the proximal part of the flap was rotated into the defect as a rotational flap. The procedure and the follow-up have been photo-documented in all cases. Furthermore, the perfusion of the flaps was monitored by means of laser Doppler flowmetry. Postoperative complications were evaluated with a semi-quantitative score and the patients completed a patient satisfaction questionnaire, too. Results: An optimal esthetic result was obtained in all cases after the operation. The lateral nasal alar part of the defect was reconstructed with the thinner proximal part of the flap while the deeper perialar region involving the upper lip was covered with the thicker distal part. The flaps have shown sufficient blood flow after the operation. There was no significant pin cushioning or "trap-door" effect in any case. Mild erythema and edema was found in few cases. The patients were satisfied with the cosmetic result of the intervention. Conclusions: The flap is suitable for the reconstruction of alar defects involving the perialar region. It has the advantage of covering the deeper perialar and the thinner alar defects, whilst eliminating the pin cushioning effect of the conventional subcutaneous island pedicle flaps.

A novel rat full-thickness hemi-abdominal wall/hindlimb osteomyocutaneous combined flap: influence of allograft mass and vascularized bone marrow content on vascularized composite allograft survival.

Vascularized bone marrow transplantation (VBMT) appears to promote tolerance for vascularized composite allotransplantation (VCA). However, it is unclear whether VBMT is critical for tolerance induction and, if so, whether there is a finite amount of VCA that VBMT can support. We investigated this with a novel VCA combined flap model incorporating full-thickness hemiabdominal wall and hindlimb osteomyocutaneous (HAW/HLOMC) flaps. Effects of allograft mass (AM) and VBMT on VCA outcome were studied by comparing HAW/HLOMC VCAs with fully MHC-mismatched BN donors and Lewis recipients. Control groups did not receive treatments following transplantation. Treatment groups received a short course of cyclosporine A (CsA), antilymphocyte serum, and three doses of adipocyte-derived stem cells (POD 1, 8, and 15). The results showed that all flaps in control allogeneic groups rejected soon after VCAs. Treatment significantly prolonged allograft survival. Three of eight recipients in HLOMC treatment group had allografts survive long-term and developed donor-specific tolerance. Significantly higher peripheral chimerism was observed in HLOMC than other groups. It is concluded that the relative amount of AM to VBMT is a critical factor influencing long-term allograft survival. Accordingly, VBMT content compared with VCA mass may be an important consideration for VCA in humans.

Objective To evaluate the efficacy of the combined saphenous nerve-great saphenous vein flap and cutaneous branches of posterior tibial artery flap in repairing refractory wounds. Methods Eighteen cases of pedal chronic ulcers were treated with the combinedsaphenous nervegreat Saphenous vein flap and cutaneous branches of posterior tibial artery flap, in which the wounds were treated with vacuum suction techniques before the operation in 6 cases. Wounds were from 8 cm× 13 cm to 1 cm× 17 cm in zine after debricement, and the designed size of the flaps was from 8 cm× 14 cm to 11 cm× 18 cm. Results After the treatment, 18 cases were evaluated as excellent in 10 cases, and good in 8 cases, in which the primary sealing of the wounds was achieved in 17 cases, but one case presented with focal necrosis of smaal size owing to vein drainage disturbance in a distallypedicled flap, and was healed after flap transplantation. Follow-up for 6 months to 2 years showed that all the patients were satisfied with the results. Conclusions The combined flap has reliable blood supply, skin pedicle of the flap is longer, superior texture and satisfied appearance, and incisive area of the flap is larger. It is particularly useful in repairing refractory wound in foot.

Repair with Combined Flap of Bilobed and Rotation of a Defect Following Mohs Micrographic Surgery

A 30-year-old man developed basal cell carcinoma 3 years ago which showed as a pea sized, crusted nodule with extending pigmentation and telangiectasia on the inner side of the right lower eyelid. Five stages of Mohs micrographic surgery were required for the complete eradication of all tumor cells in the lesions of the nodule and extending pigmentation. The defect following the surgery was 4.5 × 3.5cm and was too large to repair with a primary closure or simple single flap. So, the defect was repaired with a combined flap of glabellar bilobed and cheek rotation. We report that the combined flap of glabellar bilobed and cheek rotation is a useful and relatively simple method for the reconstruction of a large defect on the inner side of the lower eye-lid area.
