Does the use of chlorhexidine scrub prior to cutaneous surgery on the face increase the chances of toxicity to the eyes or ears? In addition, does the us eof chlorhexidine scrub on the face prior to cutaneous surgery decrease the chances of a post-operative wound infection?
Condition or disease
Corneal ToxicityOtotoxicitySurgical Site Infection
The intent of this proposed prospective observational cohort study is to determine if there is a difference in the incidence of corneal toxicity and/or ototoxicity in study subjects undergoing Mohs micrographic surgery (MMS) on the face if a povidone-iodine preparation is used pre-operatively as compared to a chlorhexidine-alcohol preparation. It has recently been found that the use of a chlorhexidine-alcohol preparation is superior to the use of a povidone-iodine preparation in preventing post-operative surgical-site infections (SSI) in patients undergoing clean-contaminated surgery. However, the use of chlorhexidine on the face has previously been associated with corneal toxicity and ototoxicity. This study will help to further define previously reported risks of corneal toxicity and ototoxicity associated with the use of a chlorhexidine solution on the face.

Ages Eligible for Study:
18 Years and older (Adult, Senior)
Sexes Eligible for Study:
Accepts Healthy Volunteers:
Consecutive patients 18 years of age or older undergoing Mohs micrographic surgery for a skin neoplasm(s) on the face at the Dermatology Surgery Center at the Mayo Clinic in Rochester, Minnesota, and at the University of Toronto in Toronto, Ontario, Canada, will be included. Exclusion criteria will include: those undergoing MMS for a lesion on the eyelid margin, patients with a history of ongoing eye pain, history of a pre-existing corneal ulcer within 12 months prior to surgery, history of a perforated tympanic membrane, and patients with an active infection at the operative site at the time of surgery. If post-operative follow-up is not completed, the study subject will be excluded from the study.
