Fig. 2From: Comparison of surgical field visibility during propofol or desflurane anesthesia for middle ear microsurgerySurgical field visibility at different time points. Average Boezaart scores for surgical field visibility at different time points were < 2 in both propofol/remifentanil (PR) group and desflurane/remifentanil (DR) group. Surgical field visibility was significantly better in the PR group than in the DR group during clearance of cholesteatoma. Tln, at skin incision; Tdr, during bone drilling; Tcl. during clearance of cholesteatoma; Tpl, during laying of fascia. *P < 0.05Back to article page
