Abstract: PURPOSE: To review and analyze the common complications after modified temporomandibular joint disc anchor, and explore the causes and prevention of postoperative complication. METHODS: The patients undergoing modified anchorage surgery were followed up since July 2011 to the December 2012. They were asked to fill in the postoperative questionnaire, which included symptoms of the facial nerve injury, numbness of the operation area, manifestations of gustatory sweating syndrome, changes of appearance and function, scar, and etc. The results were statistically analyzed using SPSS 13.0 software package. RESULTS: A total of 402 patients responded to the survey, including 72 males, 330 females, and the average age was (31.36±15.18) years. The common postoperative complications of modified temporomandibular joint disc anchoring operation included eyes closing difficulty(1.09%), row lifting difficulty(6.74%), disappearance of the wrinkles on the forehead(1.28%), upper eyelid ptosis(2.91%), numbness(14.39%), gustatory sweating syndrome(1.63%), preauricular area depression(5.28%), local alopecia(0.18%), a sense of tension during opening and closing mouth(7.47%), weakness of chewing(5.10%) and etc. CONCLUSIONS: The temporomandibular joint is complicated anatomically, which makes easier for improper operation to cause a series of complications. Rich experience and higher operation skills are required for operators.
