Objectives: To compare the responses of oropharyngeal structures to gravity while sitting upright or lying down in a supine position. Methods: Seven subjects were evaluated by cone beam CT (CBCT) position and four-row multidetector helical (MDCT) All voxel sizes adjusted be 0.3×0.3×0.3 mm3 x-y-z axis. The posterior nasal spine, basion fourth cervical bone used as references measure positional changes between positions. smallest areas oropharynx also evaluated. Results: soft palate,...
Abstract Background Patients with mandibular prognathism exhibit not only its characteristic maxillofacial morphology but also discrepancies in stomatognathic function, and understanding this function is vital for establishing a plan surgical orthodontic treatment or providing guidance recovery after orthognathic surgery. However, few studies have yet addressed the objective evaluation of masticatory before treatment. In particular, behaviors that show how you chew your daily meals,...
The aim was to evaluate the possibility of radiographic prediction prognosis simple bone cysts (SBCs) jaws.The relationship between findings and treatment outcome (healing or recurrence) investigated in 31 cases treated authors' hospital 108 published cases.In 17 our cases, lesions had a preserved lamina dura adjacent lesion, with smooth margin, no expansion, all them healed after surgery. In other 14 there resorption dura, scalloped nodular root resorption, sclerotic mass multiple cavities,...
Summary The purpose of this study was to clarify quantitatively the differences in tongue‐tip motion among dentulous elderly people and also edentulous, both with without their dentures and, identify influence tooth loss denture wear on motion. Fourteen young people, 12 13 edentulous participated study. Subjects were asked swallow a 10 mL barium sulfate solution three times. while wearing removed. Functional swallowing recorded cine‐film digital subtraction angiography system. Lateral...
Purpose The relationships between motor function, including the orofacial muscles coordinated with tongue during swallowing, and palatal morphology are still unclear. This study aimed to identify pressure production muscle activities swallowing morphology.
Metastatic retinoblastoma of the jaws is very rare. We present a 4-year-old boy with metastatic that involved both maxilla and mandible simultaneously. Enhanced CT indicated bone-destructive masses partially non-enhanced area enhanced margin in right left mandible. MRI showed well-delineated were isointense on T1 weighted images hyperintense T2 images. Four weeks after chemotherapy bone marrow transplantation, size lesions remarkably decreased. The patient died 19 months later extensive...
Abstract Background Coordination among lip, cheek and tongue movements during swallowing in patients with mandibular prognathism remains unclear. Objectives This study aimed to identify the temporal sequences of pressure maxillofacial muscle activities compared characteristics those healthy volunteers. Methods Seven (mandibular group) 25 volunteers individual normal occlusion (control were recruited. Tongue pressures masseter, orbicularis oris, mentalis supra‐ infrahyoid while gel measured...
