  • the effect of staged transverse preputial Island Flap urethroplasty for proximal hypospadias with severe chordee
    The Journal of Urology, 2016
    Co-Authors: Chao Chen, Tiquan Yang, Jiabo Chen, Ning Sun, Weiping Zhang
    Abstract:

    Purpose: We compare the effects of staged tranverse preputial Island Flap urethroplasty and the Byars 2-stage procedure in patients with proximal hypospadias and severe chordee.Materials and Methods: We studied 87 consecutive children referred for proximal hypospadias with severe chordee between March 2011 and March 2014. Of the cases 42 were repaired with staged tranverse preputial Island Flap (group 1) and 45 were managed by 2-stage Byars urethroplasty (group 2). Mean ± SD age at first stage surgery was 26.6 ± 13.3 months in group 1 and 24.8 ± 14.7 months in group 2. Postoperative complications in both groups were assessed regarding fistulas, urethral strictures, diverticula, meatal stenosis and glanular dehiscence.Results: After the second stage 2 patients (4.8%) in group 1 and 10 (23.2%) in group 2 had urethrocutaneous fistulas (p 0.05). All patients with stricture were cured by repeated dilation and no ...

  • modified first dorsal metacarpal artery Island Flap for sensory reconstruction of thumb pulp defects
    Journal of Hand Surgery (European Volume), 2016
    Co-Authors: Hui Wang, Xiaoxi Yang, Chao Chen, Huijian Zhang, Z Wang
    Abstract:

    Restoration of tactile sensation after reconstruction of a thumb pulp defect is import for hand function. We describe our clinical experience using a modified first dorsal metacarpal artery Island Flap innervated by the radial dorsal branch of the proper digital nerve and the terminal branch of the superficial radial nerve in 20 consecutive cases. The results were compared with 25 patients treated by the conventional Foucher’s first dorsal metacarpal artery Flap without nerve repair. At the final follow-up, Flap sensation was assessed using static two-point discrimination and Semmes–Weinstein monofilament testing. All Flaps survived uneventfully in both groups. At the final follow-up, the mean values for static two-point discrimination and Semmes–Weinstein monofilament testing in the study group were significantly different from the values in the control group. The modified first dorsal metacarpal artery Island Flap provides a reliable and simple option for sensory reconstruction of thumb pulp defects.Lev...

  • the dorsal homodigital Island Flap based on the dorsal branch of the digital artery a review of 166 cases
    Plastic and Reconstructive Surgery, 2014
    Co-Authors: Chao Chen, Peifu Tang, Xu Zhang
    Abstract:

    BACKGROUND: Soft-tissue reconstruction in the finger continues to evolve. This study reports reconstruction of small to moderate finger defects with the dorsal homodigital Island Flap and compares the results between the innervated and noninnervated Flaps. METHODS: A retrospective study was conducted of 166 patients who had soft-tissue defects of the finger treated with the dorsal homodigital Island Flap (187 defects in 187 fingers in 166 patients). Mean defect size and Flap size were 2.2 × 1.9 cm and 2.4 × 2.1 cm, respectively. When return of sensation was important, the dorsal branch of the digital nerve or the dorsal digital nerve was attached with the Flap to restore neurosensory function. The main outcomes were static two-point discrimination and Semmes-Weinstein monofilament scores of the Flap, fingertip pain, and joint motion. RESULTS: A significant difference was found between the innervated and noninnervated Flaps in two-point discrimination, Semmes-Weinstein monofilament, and fingertip pain. The dual-innervated Flap presented better discriminatory sensation on the Flap and a lower incidence of fingertip pain than the noninnervated and single-innervated Flap. In addition, the innervated Flap obtained better Semmes-Weinstein monofilament scores than the noninnervated Flap. For Flaps harvested from the middle phalanx, the mean active motion arc of the distal interphalangeal joint was 69 degrees (range, 35 to 90 degrees). The contralateral side measured 73 degrees (range, 45 to 90 degrees) (significant difference, p = 0.041). Maximum amplitude losses of 15 degrees were seen in 10 percent of patients in the distal interphalangeal joint. CONCLUSION: The dorsal homodigital Island Flap is an alternative for tissue reconstruction in the finger. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

  • reconstruction of a soft tissue defect in the finger using the heterodigital neurocutaneous Island Flap
    Injury-international Journal of The Care of The Injured, 2013
    Co-Authors: Chao Chen, Peifu Tang, Lihai Zhang
    Abstract:

    Abstract Background This article describes reconstruction of a soft tissue defect in the finger using the heterodigital neurocutaneous Island Flap and reports the results of the use of the Flap. Methods From February of 2008 to March of 2011, the neurocutaneous Island Flap was used in 12 patients with soft tissue defects in the middle phalanx or the proximal interphalangeal joint, or both. The injured fingers included 4 index, 3 middle, 3 ring and 2 little fingers. The donor fingers included 7 middle fingers and 5 ring fingers. The mean size of soft tissue defects and the Flaps was 2.4 cm × 1.8 cm and 2.7 cm × 2.0 cm, respectively. The mean pedicle length was 2.8 cm. Results Full Flap survival was achieved in 11 cases. Partial distal Flap necrosis was noted in one case, which healed without surgical intervention. At a mean follow-up of 22 months, the mean static 2-point discrimination and Semmes-Weinstein monofilament scores on the Flap were 8.3 mm and 3.94, respectively. Based on the modified American Society for Surgery of the Hand guidelines for stratification of 2-point discrimination, 10 (83%) of 12 Flaps achieved good results. According to the Michigan Hand Outcomes Questionnaire, 5 patients were strongly satisfied and 7 were satisfied with functional recovery of the reconstructed finger. Conclusions The neurocutaneous Island Flap of the dorsal branch of the digital nerve is useful, reliable, and technically easy for reconstructing a defect in the adjacent fingers, especially when sensory reconstruction is needed.

  • Application of Island Flap pedicled with dorsal cutaneous branches of digital internal artery for skin defect at the same finger
    Zhonghua zheng xing wai ke za zhi = Zhonghua zhengxing waike zazhi = Chinese journal of plastic surgery, 2010
    Co-Authors: Li-min Kan, Chao Chen, Hui-wen Zhang, Jian-hua Liu
    Abstract:

    Objective To investigate the therapeutic effect of Island Flap pedicled with dorsal cutaneous branches of digital internal artery for skin defect at the same finger. Methods From June 2005 to June 2008, 52 fingers in 45 cases with skin defects were treated with Island Flap pedicled with dorsal cutaneous branches of digital internal artery for skin defect at the same finger. Results Partial necrosis happened at the distal end of 4 Island Flaps. All the other Flaps survived completely. The patients were followed up for 4-8 months with satisfactory cosmetic and functional results. The two-points discrimination distance was 6. 0-9.0mm ( average, 7.4 mm) in Flaps with nerve anastomosis, and 8-10 mm (average, 9mm) in Flaps without nerve anastomosis. Minor pigmentation occurred in 5 fingers, cicatricial contracture around the skin graft in 4 fingers, and pain in donor site scar in 2 fingers. The hand function was assessed as excellent in 42 fingers, as good in 7 fingers and medium in 3 fingers. Conclusions The main artery will not be sacrified when the Island Flap is used. It is ideal for the treatment of finger skin defect. Key words: Surgical Flap;  Finger

  • supraclavicular artery Island Flap for head and neck oncologic reconstruction indications complications and outcomes
    Plastic and Reconstructive Surgery, 2009
    Co-Authors: Ernest S Chiu, Perry Liu, Paul Friedlander
    Abstract:

    Background: The supraclavicular Island Flap has been used successfully for difficult facial reconstruction cases, providing acceptable results without using microsurgical techniques. The authors use this regional Flap in reconstructing various head and neck oncologic defects that normally require traditional regional or free Flaps to repair surgical wounds. Methods: A pedicled supraclavicular artery Flap was used to reconstruct head/ neck oncologic defects. Complications and functional outcomes were assessed. Results: Head and neck oncologic patients underwent tumor resection followed by immediate reconstruction using a supraclavicular artery Island Flap. Ablative defects included neck, tracheal-stomal, mandible, parotid, and pharyngeal walls. All Flaps (n = 18) were harvested in less than 1 hour. All ablative wounds and donor sites were closed primarily and did not require additional surgery. Major complications included a complete Flap loss when the vascular pedicle was inadvertently divided and pharyngeal leaks. The leaks resolved without surgical intervention, and both patients regained the ability to swallow using their neo-esophagus. Minor complications included donor-site wound dehiscence and cellulitis. None of the patients reported functional donor-site morbidity. Conclusions: This thin Flap is easy and quick to harvest, has a reliable pedicle, and has minimal donor-site morbidity. It is now the authors' Flap of choice for many common head and neck reconstructive problems. Early experience using the supraclavicular artery Island Flap suggests that it is an excellent Flap option for head and neck oncologic disease patients.

  • a systematic review of the keystone design perforator Island Flap in lower extremity defects
    Medicine, 2017
    Co-Authors: Jiuzuo Huang, Xiao Long, Xiaojun Wang
    Abstract:

    BACKGROUND The keystone design perforator Island Flap is useful for the reconstruction of lower extremity defects. We performed a systematic review with the objective of identifying complication rates associated with using the keystone design perforator Island Flap to treat such defects. METHODS The MEDLINE, PubMed Central, Embase, and Cochrane databases were searched from January 2003 to August 2016 for articles describing keystone design perforator Island Flaps in lower extremities. The study selection was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. RESULTS Nine articles that involved a total of 282 keystone design perforator Island Flaps satisfied the inclusion criteria. In these articles, the most common cause of lower extremity defects was oncologic resection (89.0%). Most such defects were in the middle third of the lower leg (32.7%). Complications occurred in 9.6% of patients; these complications included partial Flap loss (1.1%) and complete Flap loss (0.7%). CONCLUSION Given its high success rate and low technical complexity, if applicable, the keystone design perforator Island Flap should be the preferred approach for lower extremity reconstruction.

  • reconstruction of periorbital soft tissue defect with reversed superficial temporal artery Island Flap
    Annals of Plastic Surgery, 2014
    Co-Authors: Yang Wang, Xiao Long, Xiaojun Wang
    Abstract:

    BACKGROUND Periorbital soft tissue reconstruction is a challenge because of its difficulty in regaining both the form and the function. Local Flap is the priority method because it could provide excellent match in skin color and texture. OBJECTIVE We aim to investigate the application of pedicled reversed superficial temporal artery Island Flap in the reconstruction of periorbital soft tissue defect. METHOD Different kinds of reversed superficial temporal artery Island Flaps were harvested from the auricular area to cover the defect in the periorbital area. RESULTS Ten patients who suffered congenital or acquired periorbital diseases were treated with this method. One case suffered minor venous congestion postoperatively. All the other cases achieved good aesthetic result in both the donor and the recipient sites. CONCLUSION Reversed superficial temporary artery Island Flap could be safely harvested from the auricular region even in a split pattern. It could be used to cover the periorbital defect with an unconscious scar at the donor site.
