STUDY OBJECTIVES The aims of this study were to comprehensively evaluate the cephalometric features of patients with obstructive sleep apnea syndrome (OSAS), and to elucidate the relationship between cephalometric variables and severity of the apnea-hypopnea index (AHI). PATIENTS The study population consisted of 62 male patients with OSAS, classified into 33 obese patients (body mass index [...

isolated skeletal metastasis to the bony calvarium is extremely rare in patients with squamous cell carcinoma of the uterine cervix. we describe the clinical and imaging findings in a case of squamous cell carcinoma of the uterine cervix with metastases to the bony calvarium as the sole site of metastasis. the patient was a 65-year-old woman with squamous cell carcinoma of the uterine cervix, f...

The opercle is a prominent craniofacial bone supporting the gill cover in all bony fish and has been the subject of morphological, developmental, and genetic investigation. We surveyed the shapes of this bone among 110 families spanning the teleost tree and examined its pattern of occupancy in a principal component-based morphospace. Contrasting with expectations from the literature that sugges...

BACKGROUND Primary nasal natural killer (NK)/T-cell lymphoma is the most common cellular subtype seen in nasal lymphomas. It is rare in the Western population but occurs more frequently in Asia, South America, and Mexico. The purpose of this study was to describe the computed tomography (CT) and magnetic resonance (MR) imaging findings of primary nasal NK/T-cell lymphoma. METHODS During the p...

The success of flapless immediate implant placement is dependent on the bony architecture on the buccal aspect of the socket. The presence of a fenestration defect in the buccal cortical plate may jeopardize the esthetic outcome, especially if the clinician does not undertake adequate soft and hard tissue augmentation procedures. This article describes the use of an esthetic buccal flap design ...

Few successful treatment modalities exist for surface-wide, full-thickness lesions of articular cartilage. Functional tissue engineering offers a great potential for the clinical management of such lesions. Our long-term hypothesis is that anatomically shaped tissue constructs of entire articular layers can be engineered in vitro on a bony substrate, for subsequent implantation. To determine th...

Although the superbly preserved specimens of Onychodus jandemarrai have greatly advanced our understanding of the Onychodontiformes, a primitive sarcopterygian group with large parasymphysial tooth whorls, the scarcity of the otoccipital material in the group hampers further morphological comparisons between onychodonts and other sarcopterygian groups. Here we report a new onychodont Qingmenodu...
