Coronal cavities are regions of low coronal emission that usually sit above solar prominences. These systems can exist for days or months before erupting. The magnetic structure of the prominence-cavity system during the quiescent period is important to understanding the pre-eruption phase. We describe observations of a coronal cavity situated above a solar prominence observed on the western li...

A 36-year-old woman presented with a 1-year history of headaches and increasing retroorbital pain on the right. Contrast-enhanced CT in axial and coronal planes showed a large low-density lesion in the skull base on the right (Figs. 1 A-1 C). This appeared as an expansile intradiploic cavity within the greater wing and body of the sphenoid, clivus, and right side of the sphenoidal sinus, with e...

suffering from febrile convulsions. Previous studies of clinical applications of rectal DZP have shown that intermittent administration of DZP suppositories during the febrile period prevents recurrent febrile convulsions. In addition to DZP suppository, acetaminophen (AAP) suppositories are occasionally used to ease suffering by high fever. However, the simultaneous combination of DZP and AAP ...

schwannoma is a benign encapsulated slow-growing tumor that originates from schwann cells of the peripheral nerve sheath. it usually occurs in the head and neck; however, it is rare in the oral cavity. the tongue is the most common site of intraoral schwannomas, followed by the floor of the mouth, palate, gingiva, vestibular mucosa, lips and mental nerve area. we report a rare case of schwannom...

BACKGROUND Multilevel obstruction in obstructive sleep apnea commonly includes retroglossal obstruction. To improve surgical success rates, tongue volume reduction with posterior midline glossectomy and/or lingual tonsillectomy is widely performed. METHODS Nasotracheal intubation was utilized, and the combined tongue procedure was performed as a final step after palatal surgery. The tongue wa...

UNLABELLED Microorganisms remaining in dentin following cavity preparation may induce pulp damage, requiring the use of pulp-capping agents with antimicrobial activity underneath permanent restorations. OBJECTIVE The aims of this study were to analyze the bacteriological status of carious dentin and to assess the efficacy of different base underneath silver amalgam restorations. MATERIAL AN...

A novel robotic system “NeuRobot” is currently being developed at the Computer Integrated Medical Intervention Laboratory, in collaboration with the National Neuroscience Institute and Volume Interactions, for Skull-Base Surgery. It is funded by the Ministry of Education. Skull-Base Surgery (“SBS”) is a procedure that requires a bone removal tool to be used to create a cavity (a “task-envelope”...

PURPOSE To describe a technique of vitreous base visualisation through trans-scleral illumination using a standard 25-gauge light probe. METHODS All vitrectomies are performed using 25-gauge+ instruments and valved trocars. A non-contact viewing system is used to visualise the retina. After core vitrectomy and the necessary additional procedures, triamcinolone acetonide (Kenacort) is injected...

We report a case of foreign body presence in the ethmoid sinus cavity with anterior skull base fracture and visual loss. A 42-year-old male had an uncertain history of trauma and a penetrating wound near the left medial canthus. Computed tomography imaging showed a 3.0-cm bottle cap penetrating into the anterior skull base. He underwent foreign body removal, canalicular repair, ethmoidectomy, a...

Teratomas are neoplasms composed of tissues from all three germ layers with varying degrees of differentiation. They are most commonly found in the sacrococcygeal and gonadal regions and rarely occur in the head and neck region. A teratoma is termed "epignathus" when it arises from the skull base or hard palate and is located in the oral cavity. The authors describe a case of a giant epignathus...
