An observational study in Corneal Toxicity, Ototoxicity and Surgical Site Infection, sponsored by Mayo Clinic. Completed at 1 site in United States. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2013-10-24.

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?
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.
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.
Exclusion Criteria:
Ocular and Ear Toxicities
Comparing ocular and ear toxicities between two institutions with differences in aseptic technique.
Time frame: 1 year
Infection rates
compare the infections rates between two institutions with different skin prep practices
Time frame: 1 year
