    Advantages of ultrasound guidance for TMJ arthrocentesis and intra-articular injection: A narrative review
    (Wroclaw University of Medicine, 2022-10) De Nordenflycht, Diego; de Souza Tesch, Ricardo
    Ultrasound (US) is a widely available, low-cost, non-invasive, and safe medical imaging method that enables real-time observation. Ultrasound offers several advantages for dentomaxillofacial images, such as portability, the possibility of dynamic and repeated examinations, patient comfort, and availability. It is a useful tool for recognizing the temporomandibular joint (TMJ) structures and their involvement during the course of different pathological processes, such as articular disk displacement, joint effusion and cortical erosion. In addition to its diagnostic use, US has been proposed as an auxiliary tool in minimally invasive procedures for arthrogenic temporomandibular disorders (TMD) to achieve an accurate puncture, recognize joint spaces and reduce surgical trauma. While US is widely used for large joints to visualize internal structures and guide the injection, this technique has only recently gained popularity for the TMJ procedures. Hence, the literature on this topic is scarce. The present review describes the potential advantages and the clinical technique of US guidance for TMJ arthrocentesis and intra-articular injection (IAI). © 2022, Wroclaw University of Medicine.

    Thermoformed occlusal splints for the treatment of masticatory muscle pain: a clinical trial
    (Universidade Estadual Paulista, Institute of Science and Technology of Sao Jose dos Campos, 2022-07) De Nordenflycht, Diego; Salinas, Javier; Armstrong, Lisa
    Objective: Compare the clinical effectiveness of custom thermoformed occlusal splints (OS) alongside behavioral and self-care therapy (BST) in the management of myalgia of the masticatory muscles. Material and methods: A controlled clinical trial was conducted with a total of 46 subjects with a diagnosis of myalgia according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). All subjects were treated with BST at the beginning of the study and were then randomized into four groups: behavioral and self-care control group; Thermoformed Tough-elastic splint group; Thermoformed Soft-elastic splint group, and non-occlusive splint group. Follow-ups were carried out at 2, 6, and 10 weeks, where it was evaluated: pain in the masticatory muscles, mandibular range of motion, mandibular functional limitation, and occlusal discomfort. Data were analyzed with Doornik and Hansen, Shapiro–Wilk, and ANOVA at p=0.05. Results: All the variables showed significant improvement (p[removed]0.05), while the Thermoformed Tough-elastic splint was the most efficient in terms of the mandibular functional limitation. The occlusal discomfort decreased over time, but without statistically significant differences in terms of time and design of OS. Conclusion: The addition of thermoformed OS to behavioral and self-care therapy does not have a significant impact on myalgia of the masticatory muscles. © 2022, Universidade Estadual Paulista, Institute of Science and Technology of Sao Jose dos Campos.

    Three-dimensional assessment of Upper Airway in Class III patients with different facial patterns
    (Medicina Oral S.L., 2023) De Nordenflycht, Diego; Corona, Tomás; Figueroa, Alejandro
    Background: To evaluate three-dimensionally the upper airway (UA) of class III adults with different facial patterns. Material and Methods: a cross-sectional study was conducted, in which cone-beam computed tomography (CBCT) images from a private clinic in Viña del Mar, Chile were evaluated. The sample consisted of CBCT images of 59 skeletal class III subjects (33 females and 26 males, mean age 24.7 years) in which the vertical facial pattern was determined using the Vert index, and the minimum cross-sectional area and total volume of the UA were measured. The minimum cross-sectional area variable was analyzed by ANOVA and the total volume was analyzed by Kruskal- Wallis test. Statistical analyses were performed with JASP 0.13.1 software at p=0.05. Results: the sample included images of 21 brachyfacial, 14 mesofacial and 24 dolichofacial subjects. The mean minimum cross-sectional area of the sample was 591.78 mm2 +/- 149.38 mm2 (minimum=352.00 mm2; maximum= 971.00 mm2), being greater in brachyfacial than in dolichofacial and mesofacial subjects, however, these differences were not significant (p=0.147). The mean total volume of the sample was 13.40 +/- 4.69 cm3 (minimum= 7.16 cm3; maximum=25.66 cm3), being greater in brachyfacial than in dolichofacial and mesofacial subjects, however, these differences were not significant (p=0.353). Conclusions: Considering the limitations of the present study, the vertical facial pattern does not appear to significantly influence upper airway measurements in skeletal class III adults. © Medicina Oral S.
