Double-contrast Arthrotomographic Follow-up Study of Arthroscopic Lysis and Lavage Operation for Superior Joint Compartment of the TMJ

Abstract

Nine joints of arthroscopic surgery patients were studied postoperatively by dual-space, double-contrast arthrotomography. The postoperative clinical conditions of patients were estimated by Sanders' standard. 5 cases were excellent, 2 cases were good and 2 were poor. Three out of 5 excellent cases showed resorptive bone change of the condyle and eminence in their postoperative condition. Two good and two poor cases did not have resorptive bone change. Four out of the 5 excellent cases had altered disk configuration. In all of the 5 excellent cases, fibrous adhesions in superior joint compartment were absent. Five excellent, two good and one poor cases showed a decrease of the size of the superior joint compartment.
