Subgaleal drain versus dissection of subgaleal space and closure without drain after burr-hole drainage of chronic subdural hematoma.

Background: Chronic subdural hematoma (CSDH) is a collection of blood, blood degradation products, and fluid that accumulate on the surface of the brain between its arachnoid and dural coverings. This study is to evaluate the efficacy of subgaleal drain (SGD) versus subgaleal dissection without drainage as adjuncts to burr-hole evacuation of CSDH.

Methods: A retrospective study was conducted utilizing the data of 60 patients operated for symptomatic CSDH.

Microvascular Decompression versus Radiofrequency Ablation in Trigeminal Neuralgia of the Maxillary and Mandibular Divisions.

 Although medical treatment is the mainstay of therapy, in trigeminal neuralgia (TN), patients failing to respond to it make them candidates to ablative or nonablative procedures.  The aim of this study was to compare the outcome of Microvascular decompression (MVD) and radiofrequency (RF) thermocoagulation in the management of TN affecting the mandibular and maxillary divisions.  Retrospective analysis of the data of 40 patients suffering from intractable classical TN affecting the maxillary or mandibular divisions or both was carried out.
