To evaluate the temporomandibular joint (TMJ) and respiratory function in pre-and postoperative patients undergoing elective cardiac surgery with tracheal intubation (TI) and verifying the correlation between Clinical dysfunction index (CDI) with lung function. Patients were evaluated during the first and second days after surgery (PO1, PO2) of cardiac surgery with 24 hours of intubation. For the evaluation of the TMJ was used CDI and for respiratory function were used cirtometry axillary, xiphoid and umbilical, and respirometry, including vital capacity (VC), minute volume (MV) and respiratory rate (RR). Thirteen patients completed the study. There was no statistical difference between the CDI at different stages of evaluation, and when evaluated the 5 sub-items, only the item assessing function showed significant result, p = 0.01. There was a significant decrease of the values of circumferences in the three measures and CV p <0.001. Negative correlation was found between the CDI and circumference in PO1 axillary; negative correlation between the CDI in PO2 and PO2 in xifoideana circumference, and a positive correlation between the CDI in PO2 and PO2 in the FR. It can be concluded that the CDI did not change significantly after tracheal intubation through the ages studied. Respiratory function showed a decrease in volumes and lung capacities. Cirtometry axillary and xifoideana and the FR were correlated with the CDI at different times.
