Abstract
BACKGROUND Infraorbital filler injection is a commonly used minimally invasive cosmetic procedure on the face, which can cause vascular complications. OBJECTIVE In this study, we aimed to explore the anatomical structure of the infraorbital vasculature and to establish an accurate protocol for infraorbital filler injection. METHODS The vascular structure of the infraorbital region was evaluated in 84 hemifacial specimens using computed tomography. Four segments (P1-P4) and five sections (C1-C5) were considered. We recorded the number of identified arteries in each slice and at each location and the number of deep arteries. Furthermore, we also measured the infraorbital artery (IOA) distribution. RESULTS At P1-P4, the lowest number of arteries was detected in segment P4, with a 317/1727 (18.4%) and 65/338 (2.3%) probability of total and deep arterial identification, respectively. The probabilities of encountering an identified artery at the five designated locations (C1-C5) were 277/1727 (16%), 318/1727 (18.4%), 410/1727 (23.7%), 397/1727 (23%), and 325/1727 (18.8%), respectively. The probability of an IOA being identified at C2 was 68/84 (81%). CONCLUSION We described an effective filler injection technique in the infraorbital region to minimize the associated risks.

Joo CW, Song WS, Lee MJ, Choi YJ. Insulin syringe for anesthesia in ptosis surgery: a randomized, fellow eye-controlled clinical study. Int Ophthalmol 2023; 43:2721-2730. [PMID: 36869981 DOI: 10.1007/s10792-023-02671-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Accepted: 02/19/2023] [Indexed: 03/05/2023]
Abstract
PURPOSE Unlike ordinary 30-gauge needles, insulin syringe needles are thinner and shorter and have a comparatively blunt tip. Therefore, insulin syringes may reduce injection discomfort, bleeding, and edema by minimizing tissue damage and vascular penetration. This study aimed to evaluate the potential benefits of using insulin syringes for local anesthesia in ptosis surgery. METHODS This randomized, fellow eye-controlled study included 60 patients (120 eyelids), conducted at a university-based hospital. An insulin syringe was used on one eyelid, and a conventional 30-gauge needle was used on the other. Patients were instructed to score pain in both eyelids using a visual analog scale (VAS) ranging from 0 (no pain) to 10 (unbearable pain). Ten minutes after the injection, two observers scored degrees of hemorrhage and edema in both eyelids on five- and four-pointing grading scales (0-4 and 0-3) for each value, and the average score between the two observers was calculated and compared. RESULTS The VAS score was 5.17 in the insulin syringe group and 5.35 in the 30-gauge needle group (p = 0.282). Ten minutes after the anesthesia, the median hemorrhage scores were 1.00 and 1.75 (p = 0.010), and the median eyelid edema scores were 1.25 and 2.00 (p = 0.007) in the insulin syringe and 30-gauge needle groups, respectively (Fig. 1). CONCLUSION Injecting local anesthesia using an insulin syringe significantly reduces hemorrhage and eyelid edema, but not injection pain, before skin incision. Insulin syringes are useful in patients at high risk of bleeding because they can reduce the penetrative tissue damage caused by needle insertion.

Abstract
After reading this article, the participant should be able to (1) almost painlessly inject tumescent local anesthesia to anesthetize small or large parts of the body, (2) improve surgical safety by eliminating the need for unnecessary sedation in patients with multiple medical comorbidities, and (3) convert many limb and face operations to wide awake surgery. We recommend the following 13 tips to minimize the pain of local anesthesia injection: (1) buffer local anesthetic with sodium bicarbonate; (2) use smaller 27- or 30-gauge needles; (3) immobilize the syringe with two hands and have your thumb ready on the plunger before inserting the needle; (4) use more than one type of sensory noise when inserting needles into the skin; (5) try to insert the needle at 90 degrees; (6) do not inject in the dermis, but in the fat just below it; (7) inject at least 2 ml slowly just under the dermis before moving the needle at all and inject all local anesthetic slowly when you start to advance the needle; (8) never advance sharp needle tips anywhere that is not yet numb; (9) always inject from proximal to distal relative to nerves; (10) use blunt-tipped cannulas when tumescing large areas; (11) only reinsert needles into skin that is already numb when injecting large areas; (12) always ask patients to tell you every time they feel pain during the whole injection process so that you can score yourself and improve with each injection; (13) always inject too much volume instead of not enough volume to eliminate surgery pain and the need for "top ups."

Abstract
The second part of this Hair Transplantation review concentrates on technical aspects of the surgery. First, we review the two main local anesthetics used in hair transplantation, lidocaine and bupivacaine, how to achieve long-lasting local anesthesia, and the techniques used to minimize the pain associated with anesthetic infiltrations. Second, we review the two donor harvesting techniques currently used: strip harvesting FUT and FUE. The technical aspects of each technique are described in detail, along with their advantages and drawbacks. Third, the different methods of graft implantation currently used by the majority of hair surgeons, including premade sites and stick-and-place, and the use of tools such as implanters are discussed. Finally, post-operative care, expected results, and the main complications involved in hair transplant surgery are reviewed.
