Trephine

The surgical team will fix a metal ring over the sclera, providing a base for the trephine, that is placed over the cornea, in order to cut it. ❋ Unknown (2008)

A trephine is a medical saw used to open the skull for surgery or to relieve pressure from brain swelling. ❋ Connelly, Michael, 1956- (2002)

“A trephine is the only conceivable way to save his life,” Reilly went on. ❋ PATRICIA CABOT (2001)

After ulcers of the cornea, which have been large, the inequalities and opacity of the cicatrix obscures the sight; in this case could not a small piece of the cornea be cut out by a kind of trephine about the size of a thick bristle, or a small crow-quill, and would it not heal with a transparent scar? ❋ Erasmus Darwin (1766)

An E. N.T man to whom I told the story also said it is common and wanted to refer me to a neurosurgeon, "He will simply pass a trephine though the skull into the affected area and remove the focus, by either excision or electro-cautery, and you will be cured". ❋ Unknown (2008)

After the removing of the trephine, the doctors will use the donor cornea for cutting a circular graft, meaning a button-shaped section of tissue. ❋ Unknown (2008)

"And when I saw this little boy, who had one eye done with the conventional procedure and the other with the trephine, I thought to myself, 'He's experimenting on these people'." ❋ Unknown (2007)

But he alerted hospital officials about his suspicions and then, being told Rowsey had permission to experiment with the trephine, got the American Academy of Ophthalmology to launch an investigation. ❋ Unknown (2007)

After Rowsey performed the trephine surgery on him in 1995, Rogers became legally blind. ❋ Unknown (2007)

Each of the child's eyes had undergone a different operation: one had received a cornea transplant with the standard technique, in which the cornea from a cadaver is stitched into the eye, while the other eye had received an experimental transplant, using a cutting device that surgeon James Rowsey named the Tampa trephine. ❋ Unknown (2007)

The trephine holes are too large by today's standards. ❋ Connelly, Michael, 1956- (2002)

The warrants sought the records of all male patients under the age of sixteen who underwent brain surgery entailing the use of a trephine drill between 1975 and 1985. ❋ Connelly, Michael, 1956- (2002)

The man who had been behind the desk was leaning over Harry, smiling down at him, gently bandaging the trephine wounds at his temples. ❋ Alan Edward Nourse (1960)

When it is required to trephine any part of the cranial envelope, the points which should be avoided, as being in the neighbourhood of important bloodvessels, are the following -- the occipital protuberance, ❋ Joseph Maclise (N/A)

B, within which the "torcular Herophili" is situated, and from this point passing through the median line of the vertex forwards to Z the frontal sinus, the trephine should not be applied, as this line marks the locality of the superior longitudinal sinus. ❋ Joseph Maclise (N/A)

In the latter disease, it is sometimes necessary to trephine and wash out the sinus or sinuses affected with an antiseptic solution. ❋ R. A. Craig (N/A)

The centre of the trephine hole should be at the intersection of the median line and a line joining the posterior canthi (Fig. 188). ❋ Unknown (N/A)
