Trephining for Brain Tumors

CT-guided laser probe for ablation of brain tumors

In this study, 22 patients (15-75 years old) were selected and transferred to CT scan for tumor ablation. For ablations, after prep and drep under the local anesthesia and mild sedation in proper position, small incision made and special needle inserted and guided by proper direction to the core of the tumor. Then, laser probe inserted through the needle and laser energy delivered. Although we ...

MANY complications following corneal grafting procedures may be attributed to the technical and biological problems associated with this type of surgery. It is generally agreed that accurate apposition of the graft to the margin of the incision in the recipient cornea is of the greatest importance. Manual trephining for penetrating keratoplasty frequently results in badly cut grafts, and for th...

Sclero-Corneal Trephining for Staphyloma

During 1913 I operated on 17 eyes for this condition, and the results appear to me to be sufficiently encouraging to merit publication. The cases were not selected, my object being first to satisfy myself that reduction of a staphyloma could be effected by establishing free filtration between the aqueous,...
