Botulinum Toxin Injection Pain Is Less with Smaller-Gauge Needles

By Will Boggs MD

NEW YORK (Reuters Health) - Injection of botulinum toxin type A through 32-gauge needles is slightly less painful than injection through 30-gauge needles, according to a randomized trial.

Dermatologists routinely use 30-gauge needles for facial injections of neurotoxins, prepackaged fillers, and intralesional local anesthesia, but pain is still an issue even with these small-gauge needles.

PURPOSE: Lumbar cutaneous stigmata in infants may be associated with occult spinal dysraphism and often trigger urologic evaluation including urodynamic testing. We examined whether urodynamic testing is useful in this population by evaluating the association between abnormal urodynamic test results and need for tethered cord release.
