Nasal Septum Deviation

This prospective observational study aims to evaluate the neurological safety of controlled hypotension (Mean Arterial Pressure 50-65 mmHg) during elective rhinoplasty. The investigators will assess whether this standard intraoperative hypotensive strategy causes cellular stress by measuring serum Glial Fibrillary Acidic Protein (GFAP) levels and early postoperative cognitive changes using the Montreal Cognitive Assessment (MoCA) test.

The objective of this study is to determine which of the two techniques (disarticulation septoplasty versus open surgery) offers the best functional results for correcting symptomatic deviations of the nasal septum. More specifically it's about: * Compare the improvement in respiratory symptoms between the two techniques * Analyze and compare complication rates between the two techniques * Evaluate patient satisfaction with aesthetic results (including columella deviation)

The aim of this study is to assess the effectiveness of Platelet-Rich Fibrin (PRF) in improving postoperative healing, reducing complications, and enhancing functional outcomes in patients undergoing septoplasty
