Minimizing postsurgical swelling, edema, and pain are important to the patient because of the elective nature of orthognathic surgical procedures. Closed-intraoral wound suction was placed following mandibular osteotomies in 65 consecutive patients. The volume of drainage ranged from 35 to 285 mL (mean of 113 mL). The use of closed-intraoral wound suction only minimally increased the incidence of postsurgical infection and at the same time resulted in considerable subjective improvement in postoperative facial appearance and a decrease in tissue edema and pain.
