For the an acoustic relation between TM Disorders and the function of hearing organs by tympanometry in three groups : healthy subjects (HEALTHY), subjects with click (CLICK) and TMD patients (TMD). We examined these absolute values, and obtained the following conclusion. 1. Regarding static compliance, there was a signifficant diffrence between HEALTHY and TMD, and also between CLICK and TMD, with a 1% hazzard rate. 2. Regarding impedance, there was a signifficant diffrence between HEALTHY and CLICK, (CLICK and TMD, with a 5% hazzard rate, and also between HEALTHY and TMD with a 1% hazzard rate. 3. Regarding press and ear clearance, there was a signifficant diffrence between HEALTHY and CLICK, with a 1% hazzard rate. 4. Regarding tympanogram, all of HEALTHY showed a symmetrical Type-A on both sides. In CLICK, there were 8 cases of Type-A and 17 cases of Type-As on both sides, all showing symmetricality. But in TMD, only three cases, one of the Type-A and two of the Type-As, showed symmetricality ; all the rest of the 12 cases were asymmetrical.
