The Supraorbital Keyhole Approach
Journal of Craniofacial Surgery, 2015Aim: The major aim of the present anatomical study was to demonstrate the anatomical structures that can be visualized using the supraorbital keyhole approach, both endoscopically and microscopically, from an eyebrow incision to intracranial structures. Furthermore, it defines an optimal craniotomy for surgery.

Diseases of the Colon & Rectum, 1985
The purpose of this paper is to show whether there is a keyhole deformity, its surgical significance, and how often it occurred following surgery for ulcer-in-ano. To do this, a retrospective study, over a 16-year period, of all patients admitted to the Ferguson Clinic with chief complaints of anal incontinence was undertaken. Of this group of patients,

Neuroradiology
Keyhole aqueduct syndrome is a rare progressive neurodegenerative disorder describing a unique set of neuro-ophthalmologic, neuroimaging, and histopathological findings on autopsy. A midline mesencephalic cleft communicating with the cerebral aqueduct resembling syrinx is seen on imaging and histopathology. There are 9 cases published in the literature.

ICALEO '97: Proceedings of the Laser Materials Processing Conference, 1997
The absorption of the laser energy in the keyhole is a function of the laser frequency (or wavelength), the chemistry of the material being welded and the temperature of the vapor. The absorption greatly affects the shape of the fusion zone as well as the integrity and efficiency of the laser welding process.

Nature Reviews Cancer, 2004
A large-scale study has shown that laparoscopic or 'keyhole' surgery for colon cancer is as safe and effective as conventional surgery, dispelling fears about a link with increased tumour recurrence.

Interaction of the keyhole and weld pool in laser keyhole welding
Journal of Laser Applications, 2002There are several components to the motion of the liquid material in the weld pool in laser keyhole welding. Observations have shown not only that it moves in the plane perpendicular to the axis of the laser, but also that it moves parallel to the laser beam.

Keyhole Deformity: A Case Series
Journal of Gastrointestinal Surgery, 2008Keyhole deformity is frequently encountered after posterior internal sphincterotomy but may be observed after lateral internal sphincterotomy or in patients without any history of previous anal surgery. The aim of the present study is to emphasize the surgical significance of this entity and discuss the possible strategies in the treatment of the ...

Journal of the Acoustical Society of America, 2016
The Aloha Cabled Observatory (ACO) is located on the seafloor about 100 km north of O‘ahu at 4800 m depth. Seismoacoustic T-waves generated by earthquakes in the South Pacific from Tonga-Kermadec to the Solomon Islands travel 40-70°Δ, passing through an acoustic keyhole—the Ka'ie'ie Waho channel—between O‘ahu and Kaua‘i before reaching ACO. In contrast
