Local Anesthesia Injection in Upper Blepharoplasty Surgery: A Side at a Time or Both Sides at Once? A Prospective Randomized Study

Can Local Infiltration Influence Postoperative Recovery in Upper Blepharoplasty? A Case Series Study on Two Different Infiltration Methods

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.
