Occurrence of Bruise, Hematoma, and Pain in Upper Blepharoplasty Using Blunt-Needle vs Sharp-Needle Anesthetic Injection in Upper Blepharoplasty

Abstract: IMPORTANCE Though it has been a common practice to use sharp needles to administer local anesthesia for upper blepharoplasty, the evidence for their benefit is lacking.OBJECTIVE To evaluate whether there is any benefit of using blunt-needle injection for local anesthesia when performing upper blepharoplasty to reduce postoperative bruise, hematoma, and pain. DESIGN, SETTING, AND PARTICIPANTS Randomized clinical trial of 44 patients who underwent bilateral upper blepharoplasty in an academic medical setting wer… Show more

“…3-5 14 In general, it is recommended to use small diameter needles and to slowly inject the anaesthetic agent to reduce pain during the procedure. [15][16][17][18][19][20][21] Furthermore, various studies have reported factors that help minimise pain during local anaesthesia, which include the choice of the anaesthetic agent, dilution, buffering, and skin cooling. 22 Anaesthetic injections can also lead to tissue distortion and bleeding, which further distort the anatomical structures, making it more di cult to perform surgery accurately; thus, care should be taken to limit these.…”

“…3 4 21 Various studies have been conducted to nd factors that reduce the pain of anaesthetic injections. 21 22 However, only one study has examined the difference in pain caused by the type of needle. 21 22 Yu et al reported that using 27-gauge blunt needles reduces pain and hematoma occurrence compared to using a 27-gauge conventional sharp needle during anaesthesia for upper blepharoplasty.…”
