There is a notable prevalence of temporomandibular joint dysfunction, reaching approximately 34% in the general population according to the recent studies. Individuals with such dysfunction often experience tension headaches due to increased tension in the masticatory muscles, a key symptom of temporomandibular joint dysfunction. Botulinum toxin type A injections into these muscles are utilized to alleviate the dysfunction, as this drug inhibits neuromuscular impulses, thereby reducing muscle tension. This study aimed to assess the efficacy of alleviating chronic tension headaches in patients with temporomandibular joint dysfunction through botulinum toxin type A injections into trigger points of the masticatory muscles. Sixty patients exhibiting signs of temporomandibular joint dysfunction and chronic tension headaches participated in the study. They were randomly assigned to either an experimental group receiving botulinum toxin type A injections or a control group receiving saline injections into the masticatory muscles. Injections were administered at sites with the highest muscle tension in the masseter and temporalis muscles. The reduction in chronic tension-type headaches was evaluated using a visual analogue pain scale. The results indicated a statistically significant decrease in headache intensity in the experimental group compared to the control group (P<0.001). Furthermore, the experimental group demonstrated significant treatment efficacy based on headache intensity before and after 12 weeks from the drug administration date (P<0.001).

Introduction: Some patients exhibit temporomandibular joint or muscular disorders of the masticatory system before, during, or after orthognathic surgery (OS). These are collectively referred to as temporomandibular disorders (TMDs). This systematic literature review aimed to determine the relationship between orthodontic-surgical treatment and TMDs. Methods: An electronic search of the PubMed database, supplemented by a manual search, was performed; the search included any studies published between 2021 (date of the last search in a systematic review of the literature on the subject) and June 2023 that evaluate the prevalence of TMDs during orthodontic-surgical treatment. The diagnosis of TMDs had to be established using the diagnostic algorithm “diagnostic criteria for temporomandibular disorders (DC/TMDs)”, and the diagnosis of disc displacement had to be confirmed using magnetic resonance imaging (MRI). The data were extracted and statistically analyzed. Results: Of the 100 results, seven eligible articles were included, representing a total of 529 cases undergoing orthodontic-surgical treatment. A reduction in joint noises (64.8%), arthralgia (57 to 77%), and myalgia (73 to 100%) was found after orthodontic-surgical treatment despite the fact that a minority of patients exhibited these signs and symptoms even though they were asymptomatic before treatment. The effects of OS on disc position were objectively unpredictable. After surgery, the presence of headaches decreased without significance and the risk of their occurrence was very low (1%). The studies converged toward a reduction in the amplitudes of mouth opening and lateral/protrusion movements. Finally, after the treatment, mandibular function was improved. Conclusion: Under the conditions of this study, OS seems to have a positive impact on the signs and symptoms of TMDs; however, it is not possible to predict the consequential effects on the position of the TMJ disc, whether it is initially in a normal position or displaced.

“…Some researchers consider that slower chewing is beneficial in terms of making food particles smaller and recognizing items that should not be eaten despite food and energy intake being reduced, and that faster chewing is correlated with better masticatory performance and less risk of malnutrition and metabolic syndrome in individuals with natural dentition [6,8,[13][14][15]. It has also been noted that improper rhythm can cause excessive strain on the temporomandibular joints, which is thought to be an etiological factor in temporomandibular disorders affecting 33% of people in Asian countries [16]. Given that masticatory frequency can be significantly affected by postoperative changes in the anatomy of the oral cavity (tongue, cheek, and mandible) [17], there is a need for studies of factors that impact masticatory rhythm in patients with oral tumors.…”

Background: Older adults who have undergone surgery for oral tumors are at increased risk of impaired masticatory rhythm. This study investigated the correlations between masticatory rhythm, objective masticatory performance, and subjective masticatory performance as well as factors related to masticatory rhythm. Methods: The participants were 44 adults (24 men, 20 women; age range 42~90 years old) who had undergone maxillectomy, mandibulectomy, or glossectomy and were rehabilitated with a maxillofacial prosthesis. The number of functional contact teeth pairs was confirmed by intraoral examination. Chewing rate, cycle duration, coefficient of variation (CV) for cycle duration (reflecting the stability of masticatory rhythm), and mixing ability were measured simultaneously using a mastication movement rhythm tracking device during gum chewing. Maximum occlusal force was measured using the dental prescale system. Patients’ perception of chewing ability was rated using a questionnaire. Results: The Spearman’s rank correlation test revealed that mixing ability, patient-rated masticatory scores, cycle duration, CV for cycle duration, and maximum occlusal force showed significant correlations with chewing rate. Multiple linear regression analysis identified mixing ability and the CV for cycle duration as significant predictors of masticatory rhythm. Conclusions: Factors associated with a faster chewing rate were higher mixing ability and masticatory scores, greater maximum occlusal force, shorter cycle duration, and smaller CV for cycle duration. Stable masticatory rhythm and mixing ability are significant predictors of chewing rate. Poor masticatory performance and unstable masticatory rhythm can result in slower chewing and thus a higher risk of inadequate dietary intake.
