Oligodendrogliomas comprise approximately 4% of the total of brain tumours, and of this group only 7% are found in the posterior fossa, including 2% in the fourth ventricle. Oligodendrogliomas of the fourth ventricle therefore comprise less than one case in 1,000 to 1,500 brain tumours (0 08 %). One cannot expect to encounter much more than one in a lifetime even in a large-neurosurgical experi...

A mandibular fossa depth correlation with dental condition and age in humans. 120 fresh male mandibular fossas were measured from the deepest area of the fossa to a horizontal reference line. The samples were classified according to age and dental state (dentate, partially dentate and totally edentulous) and a multivariate analysis was employed. Subjects average age was 41.1 (20-85). There were...

BACKGROUND The infratemporal fossa anatomy, from an endoscopic standpoint, is poorly understood. Our purpose was to design an anatomic model that illustrates the anatomy of the infratemporal fossa from the endoscopic standpoint and serves as a training model for surgeons interested in pursuing this endeavor. METHODS Red and blue silicone dyes were respectively injected into the great vessels ...

aneurysmal bone cyst (abc) is an expansile bone lesion that usually involves the long bones. skull base involvement is rare. hereby, we describe a 17-year-old man with hoarseness, facial asymmetry, left sided sensorineural hearing loss and left jugular foramen syndrome. ct scan and mri showed a skull base mass that was confirmed as abc in histopathology. the case was unusual and interesting due...

It is a commonly held misconception among Irish dentists that only minor malocclusions can be treated with lingual appliances. This article demonstrates the use of contemporary completely customised lingual orthodontic appliances to treat a diverse range of malocclusions, to a satisfactory level, and thereby may disabuse clinicians of the belief that only minor malocclusions can be treated with...

Lingual duplication cysts are rare in the pediatric population and exceedingly rare in adults. Imaging is an important part of the evaluation of lingual lesions and is helpful in defining the location and extent for surgical planning. We present a lingual duplication cyst and discuss the imaging findings and radiologic differential diagnosis.

OBJECTIVE To evaluate the effect of body mass index (BMI, calculated as weight in kilograms divided by height in meters squared) and medical comorbidities on outcomes after lingual tonsillectomy and supraglottoplasty performed for obstructive sleep apnea syndrome (OSAS) caused by lingual tonsillar hypertrophy and occult laryngomalacia. DESIGN Retrospective case review series SETTING Academi...

Head vascular anatomy of the greater (or Caribbean) flamingo (Phoenicopterus ruber) is investigated and illustrated through the use of a differential contrast, dual vascular injection technique, and high-resolution X-ray computed tomography (CT), allowing arteries and veins to be differentiated radiographically. Vessels were digitally isolated with segmentation tools and reconstructed in 3D to ...
