Association between clinical symptoms and CT findings in chronic rhinosinusitis

This study was conducted to find out the association between the clinical symptoms of chronic rhinosinusitis [CRS] and CT findings. 50 patients with CRS were studied. Their clinical symptoms were recorded according to the sinonasal outcome questionnaire [SNOT-20] and their CT findings were graded by the Lund-Mackay grading system. The Pearson correlation coefficient was assessed between these two scores. Also we used multiple regression models for adjusted association among variables. The mean +/- SD of SNOT-20 and the Lund-Mackay score were 45 +/- 8.7 [range: 29- 67] and 18.5 +/- 5 [range: 8-24], respectively. The mean +/- SD SNOT-20 score was higher for postnasal drip [PND] and facial pain; the lowest mean scores were for dizziness and ear pain. Pearson's correlation coefficient of SNOT-20 and the Lund-Mackay grading system was 0.74 [p=0.0001]. In simple regression analysis considering the Lund-Mackay score as dependent variable and SNOT symptom domains [nasal, oropharyngeal, sleep, facial, and systemic] as independent variables, the best associated clinical symptom domain was the nasal symptom domain [model r2=0.76; p<0.0001]. In the multivariate linear regression model, considering the five symptom domains as independent variables, the model r2 was 0.8 [p<0.0001] and the only significant variable in the model was the nasal symptom domain [p<0.0001]. Patients with higher symptom scores are more likely to have CT imaging evidence of rhinosinusitis

Introducing a new technique for hypophyseal tumors; endoscopic transrostal approach

Surgeries on hypophyseal tumors and other sellar lesions are among the most common practice of otolaryngologists and neurosurgeons. The present article reviewes historical evolution in endoscopic approach to sellar lesions and introduces a new technique to get easy access to sella turcica through a much safer and even less invasive approach. Materials and For this article, we have searched in medical literature by means of various keywords such as pituitary adenoma, surgery, endoscopy, endoscopic hypophysectomy, complication, pituitary surgery, etc. Finally. We introduce our new technique to approach sella turcica. We believe that the new approach could significantly reduce complications and associate with further patient's convenience
