Endoscopic Transorbital Surgery for Trigeminal Schwannoma: Introduction of a Novel Approach: 2-Dimensional Operative Video.

Indications Corridor And Limits Of Exposure: The major indications of endoscopic transorbital approach include spheno-orbital meningiomas, cavernous sinus lesions, and Meckel cave lesion such as trigeminal schwannomas. It can avoid excessive brain retraction and allows for a fast recovery to the normal daily living activity.

Anatomic Essentials Need For Preoperative Planning And Assessment: To access the cavernous sinus, the sagittal crest and meningo-orbital band should be identified and cut.

Feasibility and efficacy of endoscopic transorbital optic canal decompression for meningiomas causing compressive optic neuropathy.

Objective: The endoscopic transorbital approach (ETOA) and transorbital anterior clinoidectomy have been suggested as novel procedures through which to reach the superolateral compartments of the orbit, allowing optic canal decompression. However, there is limited literature describing the technical details and surgical outcomes of these procedures. In this study, the authors aimed to analyze the feasibility and efficacy of endoscopic transorbital decompression of the optic canal through anterior clinoidectomy for compressive optic neuropathic lesions.

Serotypes of Streptococcus pyogenes isolated from healthy school children in Kangwon-do.

Seventy-seven Streptococcus pyogenes strains isolated of children of three elementary schools located in Kangwon-do in spring, 1992 were serotyped with M, opacity factor (OF) and T typing antisera. In the M/OF typing results, M-78 (46.8%) and M-28 (22.

Optimal site of throat swab for the isolation of beta-hemolytic streptococci.

The optimal site for the isolation of beta-hemolytic streptococci (BHS) from throat cultures was investigated in 164 healthy elementary school children. All throat cultures were streaked onto duplicate blood agar plates (BAP), one of which was taken from the tonsillar fossae and the other from the posterior pharynx. BHS were isolated in cultures from 56 (34.
