RT Journal Article SR Electronic T1 Oral Nitroglycerin and Hair Transplant Surgery JF International Society of Hair Restoration Surgery FD Publication of the International Society of Hair Restoration Surgery SP 130 OP 131 DO 10.33589/30.4.130 VO 30 IS 4 A1 Muhammad Humayun Mohmand A1 Muhammad Ahmad YR 2020 UL http://www.ISHRS-HTForum.org/content/30/4/130.abstract AB Hair restoration surgery is performed under local anesthesia. The use of epinephrine reduces blood loss during the procedure. However, a few cases of scalp necrosis related to the use of local anesthetics with epinephrine have been reported, especially in smokers. We present a case report in which the area of early necrosis was prevented from advancing by using nitroglycerin (sublingual).
