      Two hundred five patients were examined for temporomandibular joint pain and dysfunction and specifically for tenderness to muscle palpation. Arthrograms were performed on 222 joints (188 unilateral and 17 bilateral). Significant findings were ascertained for the middle portion of the temporal muscle in “normal” patients versus “with and without meniscus reduction” patients. The superficial masseter muscle was more tender in “normal” patients and in “reducing meniscus” patients than in “without meniscus reduction” patients. The medial pterygoid muscle was more tender in “normal” patients and in “without meniscus reduction” patients than in “reducing meniscus” patients. Though there are some significant findings with respect to muscle palpation, by itself muscle palpation is not a specific indicator of temporomandibular joint internal derangement.
