Summary
Intubation, whether oral or nasal, can cause temporary disturbances in the stomatognathic system, affecting temporomandibular joint (TMJ) function. This study verified these findings in patients undergoing anesthesia.
Area of Science:
- Anesthesiology
- Dental Medicine
- Oral and Maxillofacial Surgery
Background:
- Intubation is a common procedure during anesthesia.
- Previous studies suggest intubation may cause temporary disturbances in the stomatognathic system.
Purpose of the Study:
- To verify the occurrence of temporary stomatognathic system disturbances after intubation.
- To compare the effects of oral intubation, nasal intubation, and face mask anesthesia on the stomatognathic system.
Main Methods:
- A double-blind study involving 140 patients (ASA groups I and II) undergoing surgery outside the head and neck area.
- Three groups: oral intubation (n=50), nasal intubation (n=40), and face mask (n=50).
- Dental examinations preoperatively and on postoperative days 1, 2, and 3. Additional interviews with 400 patients regarding temporomandibular joint (TMJ) symptoms post-intubation anesthesia.
Main Results:
- Oral and nasal intubation groups experienced temporary disturbances in the stomatognathic system.
- No significant differences in age, sex, or preoperative TMJ findings between groups.
- Women reported more preoperative stomatognathic disorders than men.
Conclusions:
- Intubation, particularly oral and nasal routes, can lead to temporary stomatognathic system disturbances.
- The findings support the need for careful consideration of intubation methods and potential TMJ impacts.
- Further research may explore preventative strategies for intubation-related stomatognathic issues.
