Introduction: An emerging treatment for chronic subdural hematomas is subdural craniostomy using a twist drill port system. While this system has the advantage of being placed in the intensive care setting, and not the operating room, incomplete hematoma evacuation is not uncommon. We detail a simple surgical technique that can be used for persistent or recurrent collections. Materials and Meth...

Composite materials are widely employed in the naval, aerospace and transportation industries owing to the combination of being lightweight and having a high modulus of elasticity, strength and stiffness. Drilling is an operation generally used in composite materials to assemble the final product. Damages such as the burr at the drill entrance and exit, geometric deviations and delamination are...

OBJECTIVE To evaluate the results of surgical treatment options for chronic subdural haematoma in contemporary neurosurgery according to evidence based criteria. METHODS A review based on a Medline search from 1981 to October 2001 using the phrases "subdural haematoma" and "subdural haematoma AND chronic". Articles selected for evaluation had at least 10 patients and less than 10% of patients...

Aim: To compare two most common operative procedures used in patients with chronic subdural hematomas Twist drill craniostomy and Burr Hole Craniostomy. Material and Methods: The study was a prospective randomized controlled trial on patients with chronic subdural hematomas. Results: Both procedures are comparable with respect to outcome but surgical duration is statistically higher in Burr Hol...

Ultrasonography has become a common method for evaluation of the central nervous system. We present our experience with ultrasonography monitoring with a burr-hole transducer for investigation of intracranial lesions. Common indications for this technique included guidance for placement of catheters, localization of masses, aspiration of cystic lesion, and confirmation of removal. Postoperative...

AIM To investigate the effects of emergency burr hole drainage for acute subdural hematoma (ASDH) with bilateral non-reactive pupils. MATERIAL AND METHODS A retrospective study was conducted by reviewing medical records from 1998 to 2007. Patients meeting the following criteria were included: 1) head injury with unconsciousness (Glasgow Coma Scale score 8); 2) bilateral non-reactive pupils on...

Chronic subdural haematoma is a common neurosurgical condition and surprisingly surgical treatment ranges from twist drill craniostomy to more radical membranectomy. However, the outcome is generally favourable with appropriate therapy. This retrospective study is aimed at analyzing the result of single burr hole drainage of such haematoma under local anaesthesia over a period of fifteen years....

Neurosurgery is a very special field among the many branches of medical science. It is filled with challenges and excitement. Looking back into the history, it seems that the trephination was performed approximately 5000 years ago. Skulls are found in Europe, Oceania, and Tibet; some of these have a sharp-edge hole in them. However, the actual instruments used by the aboriginal people and their...
