Background:

The use of local anesthesia has allowed for the excision and repair of lesions of the head and neck to be done in an office-based setting. There is a gap of knowledge on how surgeons can improve operative flow related to the onset of action. A prospective trial was undertaken to determine the length of time for full anesthesia effect in the head and neck regions.

Methods:

Consecutive patients undergoing head and neck cutaneous cancer resection over a 3-month period were enrolled in the study. Local anesthesia injection and lesion excision were all done by a single surgeon. All patients received the standard of care of local anesthesia injection.

Results:

Overall, 102 patients were included in the prospective trial. The upper face took significantly longer (153.54 seconds) compared with the lower face and ears (69.37 and 60.2 seconds, respectively)(P< 0.001) to become fully anesthetized. In addition …
