Surgeons usually use the superior gluteal artery perforator flap (SGAP) by rotational fashion, which risks complications, such as wound dehiscence or skin necrosis at the Y\u2010point on the donor site due to the tension. In this report, the authors present the experience of using trilobed pedicled SGAP flaps in coverage of the lumbosacral area defects.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>From 2011 to 2015, 16 trilobed pedicled SGAP flaps were performed for the coverage of sacral defects in our facility. The average defect sizes were 9.3 cm \u00d7 7.4 cm (ranging from 5 cm \u00d7 4 cm to 13 cm \u00d7 13 cm ). Trilobed flap were designed to include a reliable perforator vessel and rotated 90 degrees to the defect. All flaps included only one perforator vessel.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The average of flap sizes were 15.9 cm \u00d7 9.2 cm (ranging from 10 cm \u00d7 20 to 5 cm \u00d7 15 cm). Two cases of minimal distal margin necrosis (&lt;1 cm) were reported in the flap tip area. The unviable distal area was completely healed after the excision and primary closure. All flaps survived completely. Patients were followed for an average of 14.8 months postoperatively (ranging 6\u201320 months). There was no recurrence of the pressure sore during the follow\u2010up period.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Trilobed pedicled SGAP flap successfully reconstructed various sized defects and reduced the distortion and tension of the wound, minimizing wound complications. This flap could reduce the hospital stay and the recurrence of the pressure sore.<\/jats:p><\/jats:sec>","DOI":"10.1002\/micr.30172","type":"journal-article","created":{"date-parts":[[2017,4,20]],"date-time":"2017-04-20T09:08:53Z","timestamp":1492679333000},"page":"890-895","source":"Crossref","is-referenced-by-count":11,"title":["Trilobed pedicled superior gluteal artery perforator flap for lumbosacral defect coverage"],"prefix":"10.1002","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9819-0775","authenticated-orcid":false,"given":"Ji Min","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Plastic Surgery College of Medicine, The Catholic University of Korea Seoul Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun Ho","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Plastic Surgery College of Medicine, The Catholic University of Korea Seoul Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Deuk Young","family":"Oh","sequence":"additional","affiliation":[{"name":"Department of Plastic Surgery College of Medicine, The Catholic University of Korea Seoul Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Suk\u2010Ho","family":"Moon","sequence":"additional","affiliation":[{"name":"Department of Plastic Surgery College of Medicine, The Catholic University of Korea Seoul Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2017,4,20]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/00006534-199804040-00015"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.bjps.2008.11.086"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/PRS.0000000000001408"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.bjps.2013.12.029"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1155\/2016\/8714713"},{"key":"e_1_2_6_7_1","first-page":"5","article-title":"Trilobed flap in facial reconstruction","volume":"35","author":"Hisashi Ohtsuka Y.
