Abstract
Upper blepharoplasty is a common aesthetic surgery procedure which is frequently performed
wide awake, under local anesthesia. However, advancements concerning the patients'
perception during and after the procedure are still needed. This study aimed to evaluate
the efficacy of a new method for local anesthetic infiltration in the upper eyelid
comparing it to the traditional needle injections.
A prospective, randomized, and clinical trial was conducted on 20 patients who underwent
upper eyelid blepharoplasty in local anesthesia. After randomization, one eyelid was
infiltrated using a Nanosoft technology needle, while on the contralateral side traditional
needle injections were performed. Preoperative demographics, Fitzpatrick, and SNAP
test were recorded. Postoperative patients visual analog scale (VAS) scores for both
infiltration methods and ecchymosis and edema were recorded.
Our results showed that the mean VAS scores for perceived pain were significantly
lower on the eye infiltrated with Nanosoft technology (p < 0.05). Furthermore, the rate of postoperative ecchymosis and edema were also significantly
lower with Nanosoft technology (p = 0.0012 and 0 = 0.0197, respectively). All 20 patients were satisfied with outcomes,
and there were no major complications or need for a revision.
Our case series study suggests that Nanosoft technology may be a more effective and
efficient method for the local anesthetic infiltration in upper eyelid blepharoplasty
in reducing discomfort and downtime for the patient.
