BACKGROUND: Perceived pain during local anesthesia injections can be effected by the injection sequence.

OBJECTIVE: We sought to compare pain levels during local anesthesia injections during upper lid blepharoplasty (ULB) using 2 surgical sequences.

MATERIALS AND METHODS: We conducted a prospective, randomized clinical trial. Patients with ULB were randomized to either have local anesthesia injection followed by ULB in the right eyelid and then in the left (Group A) or to have local anesthesia injection to both eyelids followed by ULB on both eyelids (Group B). Pain was assessed using a visual analog scale (VAS) for pain score of 0 to 10.

RESULTS: Forty patients were included and randomized. The mean VAS score in Group A was 2.60 ± 1.84 and 3.30 ± 1.62 (right and left, respectively, p value = .035). The mean VAS score in Group B was 2.55 ± 1.63 and 2.80 ± 1.67 (right and left eyelids, respectively, p value = .258). No intergroup difference in pain was found.

CONCLUSION: Patients having sequential anesthesia during ULB perceived more pain on injection to the second eyelid, whereas patients having local anesthesia followed by ULB perceived the same amount of pain in both eyes. Pain levels in both groups were similar. Local anesthesia injections in both groups were well tolerated.
