Endonasal endoscopic repair of ethmoid roof cerebrospinal fluid fistula by suturing the dura.

INTRODUCTION: Over the past 20years, improvement in surgical techniques as well advances in surgical instruments for sinus surgery has led to surgical closure of cerebrospinal fluid (CSF) leak using endoscopic approach. Minimally invasive and having lower post op morbidity, compared to traditional intracranial techniques, repairing CSF leak endoscopically has evolved to become the standard practice for management of CSF leak. DISCUSSION: Widespread use of endoscope in sinus surgery have made us more familiar with the anatomy of the sinuses as well as the skull base. In this paper, we will describe our experience of CSF repair by suturing dura under endoscopic guidance for the repair of small ethmoid roof (<1.2cm) defects.

Primary oral cancer in a Turkish population sample: association with sociodemographic features, smoking, alcohol, diet and dentition.

The aim of this multicentre case-control study was to investigate the association of a variety of factors with oral cancer in a group of Turkish patients. Questionnaires were used to investigate the sociodemographic features, smoking and alcohol consumptions, dietary habits and dental status of 79 primary oral cancer patients and 61 controls. Data were statistically analysed with Mann-Whitney U-test, Pearson Chi-square and binary logistic regression analyses to determine the odds ratios. Low level of education, gender, dietary habits, having poor oral hygiene and denture sores were associated with primary oral cancer in this patient sample; but eating salads and raw vegetables, fish, and drinking red wine were related with healthy status. Determination of the factors associated with oral cancer and of the high-risk groups would be beneficial to provide efficient screening protocols and prevention programmes for oral cavity cancers.
