Needle Microcores: Can They Pose an Occlusive Threat with Nonparticulate Injections?

SUMMARY: The incidence of vascular occlusion injuries has risen substantially along with the increasing popularity of cosmetic injectables. Among these occurrences, instances of soft-tissue ischemic events following the injection of nonparticulate solutions, such as botulinum, represent an enigmatic etiology that has yet to be fully understood. One hypothesized mechanism of injury underlying these events relates to the accidental capture and intravascular ejection of needle microcores, defined as submillimeter tissue fragments trapped by the beveled lumen of a needle during conventional injections. To test this hypothesis, the authors conducted a cytologic evaluation of dermal remnants incidentally captured by 31-G tuberculin needles following repeated injections into postrhytidectomy skin fragments. Their findings revealed the presence of dermal tissue microcores ranging from 100 to 275 µm in diameter with an overall microcoring incidence of 0.7%. These findings confirm the ability of ultrafine needles, commonly used in botulinum injections, to produce tissue microcores that may serve as causative agents of vascular occlusion with nonparticulate solutions. Awareness of this mechanism of injury may be of benefit in the early recognition and management of these rare occurrences. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, V.

#TheUglyTruth? A Qualitative Evaluation of Outcomes Photography on Instagram: Introducing the SEPIA Scoring System.

Photographs of cosmetic treatment outcomes on social media are prone to bias and misrepresentation from nonadherence to established photographic standards. However, there is currently insufficient information regarding which norms are most-commonly violated, precluding quality improvement efforts. Methods: A qualitative study of cosmetic treatment photographs published on Instagram was undertaken in accordance with the Guidelines for Reporting Reliability and Agreement Studies using a newly proposed Standards for the Evaluation of Photographs In Aesthetics (SEPIA) nine-point photograph scoring system and grading scale. Results: A total of 510 posts encompassing 2020 clinical photographs published by 102 practitioner accounts on Instagram were audited for photographic quality. The average score was 4 out of 9 (medium quality), with approximately 40% of posts scoring in the low-quality range. Zoom, lighting, timing, and presentation of multiple views were the standards most-commonly disregarded. Plastic and Reconstructive Surgery specialty and subspecialty (PRSS) practitioners scored higher (4.5/9 versus 3.1/9, P = 0.002) and had fewer low-quality posts (22% versus 54%, P = 0.001) than non-PRSS providers. Low-quality photographs were most often seen with rhinoplasty (30% versus 7%, P < 0.00001) and lip filler (60% versus 33%, P = 0.0001) compared with surgical and nonsurgical treatments, respectively, due to a higher incidence of immediate photographs and selfies. Conclusions: Before and after photographs of surgical and nonsurgical cosmetic treatment outcomes on social media are frequently of substandard quality. This study outlines specific items frequently neglected in outcomes photography to assist practitioners in maximizing adherence to established standards of photography online.

Superficially Herniated Loop of Facial Artery: A Potential Trap for the Unsuspecting Practitioner.

The anatomy of the facial artery is complex and prone to significant variations, rendering it susceptible to vascular injury secondary to injectable treatments. Despite the known variation in the course and branching pattern of this important arterial conduit, significant anomalies in the depth of the artery, including occurrences of vessel herniation, are not as well characterized. We describe an instance of a superficially herniated loop of facial artery presenting as a buccal mass erroneously targeted with an injectable suspension of triamcinolone.
