Background: The incidence of postoperative wound infection is usually not the cause of death but itincreases the length of hospital stay and cost of care and morbidity. Since their introduction a century agothere is still controversy about primary purpose of the facemasks as whether they provide protection forthe patient from surgical team or weather they protect surgical team from the patient? The Objectives ofthis study were to critically analyze and systematically review the randomized trials regardingeffectiveness of surgical facemasks in preventing post operative wound infection in elective surgery.Method: Systematic literature review and analysis of all available trials (randomized controlled trials)regarding use of surgical face masks in elective surgeries. Medline (1966–2007), Embase (1996–2007),Cochrane database, Pubmed, Google Scholar, were searched for the selection of literature for the review.Results: No significance difference in the incidence of postoperative wound infection was observedbetween masks group and groups operated with no masks (1.34, 95% CI, 0.58–3.07). There was noincrease in infection rate in 1980 when masks were discarded. In fact there was significant decrease ininfection rate (p<0.05). Conclusion: From the limited randomized trials it is still not clear that whetherwearing surgical face masks harms or benefit the patients undergoing elective surgery.Keywords: Surgical face mask, postoperative wound infection, surgical site infection, face masks,prevention of postoperative wound infection, effectiveness of surgical face mask
