PATIENTS AND METHODS The study subjects were 30 skeletal Class III patients (9 males and 21 females), with a mean age of 22.0 years (range, 16-39 years). All patients(More)
Vogt–Koyanagi–Harada (VKH) disease is one of the diseases that show choroidal detachment. However, there are few reports about VKH disease associated with annular choroidal detachment. In this study, we describe an unusual case of VKH disease with an annular choroidal detachment and absence of a serous retinal detachment. The study was an interventional(More)
PURPOSE To evaluate the clinical significance of dynamic magnetic resonance (MR) sialographic images in prognostic evaluation of saline solution irrigation of the parotid gland for the treatment of xerostomia. MATERIALS AND METHODS Morphologic findings and functional parameters were evaluated by use of dynamic MR sialography before saline solution(More)
OBJECTIVE Endoscope-assisted transoral open reduction and internal fixation (EAORIF) for mandibular condyle fractures has recently become popular because it is minimally invasive, provides excellent visibility without a large incision, and reduces surgical scarring and the risk of facial nerve injury. This report describes a retrospective clinical study(More)
To elucidate the clinical significance of imaging modalities for detection of stitch abscess after surgery in patients with oral squamous cell carcinoma (SCC). In 137 patients with oral SCC suspected of having lymph node metastases, local recurrence of tumor, or stitch abscess after surgery, the characteristic imaging findings related to lymph node(More)
Basaloid squamous cell carcinoma is a rare aggressive malignancy that is a distinct variant of squamous cell carcinoma. This report presents 2 cases of basaloid squamous cell carcinoma in the gingiva. Case 1 is a 55-year-old Japanese man who presented with a painful, red, and irregular mass on the left mandibular gingiva. Case 2 is a 65-year-old Japanese(More)
OBJECTIVES To elucidate whether fluorine-18-labeled ((18)F) fluoro-2-deoxy-d-glucose (FDG) accumulation can reflect the extent of periodontal inflammation, periapical inflammation, or dental caries. STUDY DESIGN (18)F-FDG accumulations on positron emission tomography (PET)-computed tomography (CT) were retrospectively compared with the size of the bone(More)
