We have treated SAC using follicular unit extraction (FUE). The aim of this study was to discuss that efficacy of FUE and how much hair follicular unit (FU) should be transplanted intraoperatively for the treatment of SAC.<\/jats:p><jats:p>Methods\u2003We treated 10 patients (4 men and 6 women) who had SAC using FUE.<\/jats:p><jats:p>Results\u2003The average age, alopecia size, and intraoperative hair density on the graft area were 29.8\u2009\u00b1\u200912.1 years, 29.8\u2009\u00b1\u200944.5\u2009cm2, and 34.6\u2009\u00b1\u200911.8 FU\/cm2, respectively. One year postoperatively, the average hair survival rate on the graft area was 66.3\u2009\u00b1\u20096.1%. Hair appearance was rated as good in six, fair in three, and poor in one. Among patients whose 1-year postoperative hair density was \u2265 20 FU\/cm2, five of six patients achieved good results. However, among patients whose 1-year postoperative hair density was\u2009&lt;\u200920 FU\/cm2, all four patients achieved fair or poor results. The postoperative hair density was significantly higher in patients whose 1-year postoperative hair density was \u2265 20 FU\/cm2 than in patients whose 1-year postoperative hair density was\u2009&lt;\u200920 FU\/cm2. The rate of achieving fair or poor results was significantly higher if the postoperative hair density was\u2009&lt;\u200920 FU\/cm2 than if it was \u2265 20 FU\/cm2 (p\u2009=\u20090.047).<\/jats:p><jats:p>Conclusions\u2003FU excision is useful for the treatment of scar alopecia after craniotomy. Our results suggest that the 1-year postoperative hair density should exceed 20 FU\/cm2 to achieve good outcomes.<\/jats:p>","DOI":"10.1055\/s-0042-1756286","type":"journal-article","created":{"date-parts":[[2022,12,14]],"date-time":"2022-12-14T05:46:12Z","timestamp":1670996772000},"page":"704-709","source":"Crossref","is-referenced-by-count":1,"title":["The Treatment of Linear and Narrow Scar after Craniotomy Using the Follicular Unit Excision"],"prefix":"10.1055","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0434-3583","authenticated-orcid":false,"given":"Hiromi","family":"Okochi","sequence":"additional","affiliation":[{"name":"Department of Plastic and Reconstructive Surgery, Yamanashi University, Kofu, Yamanashi, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0859-3109","authenticated-orcid":false,"given":"Masamitsu","family":"Onda","sequence":"additional","affiliation":[{"name":"Shinwa Clinic, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5575-8324","authenticated-orcid":false,"given":"Akira","family":"Momosawa","sequence":"additional","affiliation":[{"name":"Department of Plastic and Reconstructive Surgery, Yamanashi University, Kofu, Yamanashi, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0346-9923","authenticated-orcid":false,"given":"Masayuki","family":"Okochi","sequence":"additional","affiliation":[{"name":"Department of Plastic and Reconstructive Surgery, Yamanashi University, Kofu, Yamanashi, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2022,12,13]]},"reference":[{"issue":"04","key":"ref1","doi-asserted-by":"crossref","first-page":"481","DOI":"10.1097\/00000658-190704000-00001","article-title":"Experiences in cerebral surgery","volume":"45","author":"F Hartley","year":"1907","journal-title":"Ann Surg"},{"issue":"04","key":"ref2","doi-asserted-by":"crossref","first-page":"655","DOI":"10.1177\/0194599814567869","article-title":"Safety of modified coronal approach with dissection deep to temporalis fascia for facial nerve preservation","volume":"152","author":"A J Kleinberger","year":"2015","journal-title":"Otolaryngol Head Neck Surg"},{"issue":"08","key":"ref3","doi-asserted-by":"crossref","first-page":"e740","DOI":"10.1097\/SCS.0000000000005825","article-title":"Using a modified postauricular hemicoronal incision to manage unilateral zygomaticomaxillary complex fracture","volume":"30","author":"M Liu","year":"2019","journal-title":"J Craniofac Surg"},{"issue":"05","key":"ref4","first-page":"703","article-title":"Coronal approach to zygomaticomaxillary complex fractures","volume":"19","author":"Q W Zhuang","year":"2015","journal-title":"Eur Rev Med Pharmacol Sci"},{"issue":"01","key":"ref5","doi-asserted-by":"crossref","first-page":"51","DOI":"10.1016\/j.jcms.2011.01.008","article-title":"Clinical evaluation of the bicoronal flap in the treatment of facial fractures.
