“…Câmara-Souza et al observed no relationship between TMD and hyoid bone position in 80 dental students [ 19 ]. Ekici and Camci reported that the hyoid bone in patients with TMD was located closer to the cranium [ 15 ]. The inconsistencies in the findings of these studies may be probably due to inconsistent diagnostic criteria, heterogeneity in sample selection, and methodological differences.…”

“…An experienced orthodontist, blinded to the diagnoses of the patients, performed the cephalogram tracing. The Frankfort horizontal plane was considered the reference plane, and 13 hyoid-related and 18 craniofacial measurements were performed ( Figure 1 ; Table 1 ) [ 15 , 17 ]. The intra- and inter-rater reliability of cephalometric tracing was tested, and the intra-class correlation coefficients were >0.8 [ 17 , 18 ].…”

“…Patients with TMJOA exhibited the retrusion and clockwise rotation of the mandible [ 12 ]. Although no study reported the relationship between hyoid bone position and TMJOA, a few studies investigated the relationship between hyoid bone position and TMD [ 13 – 15 ]. However, the results of these studies were inconsistent.…”

Objective. To assess the differences in hyoid bone position in patients with and without temporomandibular joint osteoarthrosis (TMJOA). Methods. The present cross-sectional study was conducted in 427 participants whose osseous status was evaluated using cone-beam computed tomography and classified into normal, indeterminate osteoarthrosis (OA), and OA. The hyoid bone position and craniofacial characteristics were evaluated using cephalograms. Patients were divided into the normal group (N = 89), indeterminate OA group (N = 182), and OA group (N = 156). Descriptive statistics, one-way analysis of variance, and age- and sex-based stratified analyses were performed. P < 0.05 was considered statistically significant. Results. The differences in Hy to MP, Hy-RGn, Hy to C3-RGn, C3-RGn, and Go-Hy-Me among the three groups were statistically significant. The differences in the Frankfort-mandibular plane angle, saddle angle, articular angle, gonial angle, ramus height, and posterior facial height were statistically significant. After adjusting age and sex, the Hy-RGn and C3-RGn in the normal group were significantly greater than the OA group. No statistical differences were observed in the hyoid measurements in the stratified analyses in males or subjects less than 18 years old. The differences in Hy to MP, Hy to C3-RGn, and Go-Hy-Me in female patients among the three groups were statistically significant. The differences in Hy to SN, Hy to FH, Hy to PP, Hy to MP, Hy-RGn, Hy-C3, Hy to C3-RGn, Go-Hy-Me, Hy-S, and C3-Hy-S in adults were statistically significant. Conclusion. The differences in the hyoid bone position, mainly relative to the mandible, were statistically significant in patients with or without TMJOA. The difference pattern varied among different age and sex groups. Clinical evaluation of the hyoid position must consider the age and sex of patients. Longitudinal studies are required to clarify the causal relationship between TMJOA and hyoid bone position.

“…Patients with TMDs are reported to have specific craniofacial features such as a skeletal Class II profile, hyperdivergent growth pattern, and others [ 14 , 15 ]. Some studies found differences in cervical posture and hyoid bone position between TMD patients and normal individuals, with an elevation of the hyoid bone and cervical lordosis observed in TMD patients [ 16 , 17 ]. However, other studies have shown no differences in craniofacial morphology between TMD patients and individuals without TMDs [ 18 – 20 ].…”

Purpose. We aimed to explore the relationship between temporomandibular disorders (TMDs) and craniofacial morphology in orthodontic patients. Methods. Altogether, 262 orthodontic patients were included and divided into two groups according to their Fonseca Anamnestic Index (FAI) scores: a no-TMD group (control group, FAI < 20) and a TMD group (FAI ≥ 20). Cephalometric parameters including cranial, maxillary, mandibular, and dental parameters were traced on cephalograms. Craniofacial morphology was compared between TMD and control groups, followed by subgroup analyses based on TMD severity, gender, age, and temporomandibular joint (TMJ) symptoms. Results. The prevalence of TMDs was 52.7% among included patients (138/262). The mean age of TMD patients was higher than that of the control group. No significant difference in gender distribution between the groups was observed. The most commonly reported FAI items were misaligned teeth, neck pain, and emotional tension. The Frankfort-mandibular plane angle (FMA) was larger in the TMD patients than in the control group, whereas no significant differences in other parameters were observed. Subgroup analysis based on TMD severity revealed that FMA and anterior facial height of moderate/severe TMD patients were significantly larger than those of mild or no-TMD patients. Among male patients, the anterior cranial base length was smaller, and the anterior facial height was larger in the TMD group. Among female patients, no significant differences in craniofacial morphology between the groups were observed. In juvenile patients, overjet and overbite were smaller in the TMD group. In adult patients, SNA, ANB, FMA, and gonial angle were larger in the TMD group. Within the TMD group, patients with TMJ pain or noises exhibited characteristic craniofacial features compared to patients without these symptoms. Conclusions. Orthodontic patients with TMDs have specific craniofacial morphology, suggesting a relationship between TMDs and particular craniofacial features in orthodontic patients.

“…The temporomandibular disorders (TMDs) consequences on craniocervical posture and hyoid bone position have been studied, even though results are still inconclusive [14]. Studies have shown that TMD is related to the position of the hyoid bone and the craniofacial anatomy and not to the craniocervical posture [15]. Characteristics of the cervical spine in patients with TMD show a lower pressure pain threshold and limited cervical range of motion [16].…”

(1) Background: This study aimed to perform a literature review related to disk displacement (DD) in class II malocclusion or cervical vertebrae position alterations and to report a hypodivergent case with cervical pain and right anterolateral DD with reduction, left anterolateral DD with reduction, and left joint effusion. (2) Methods: A structured electronic search was conducted between March 2022 and April 2022, without time limits, following PRISMA guidelines, in the following databases: PubMed, Scopus, Embase and Cochrane; the terms “disc displacement”, “disk displacement”, “temporomandibular joint”, “class II malocclusion” and “cervical vertebrae” are searched. (3) Results: the following thirteen publications are included in this review: two prospective studies and eleven cross-sectional studies; for evaluating disk position, eight included publications used magnetic resonance imaging (MRI), whilst six studies used lateral cephalogram to determine craniofacial morphology and relationships between the cranial base, vertical skeletal pattern, maxilla and mandible. (4) Conclusions: although the literature still shows contradictory opinions, a relationship between temporomandibular disorders and cervical posture has been shown in the presented case as well as in the literature review.
