The concept of Evidence Based Medicine (EBM) has flourished in recent years and it seems that clinicians, more than ever, crave evidence from the medical literature to inform their clinical care decision making. While it is heartening that great volumes of evidence may exist, it is a daunting task to assimilate, critically review, prioritize, grade, and operationalize this crucial information. This volume of Otolaryngologic Clinics attempts to do just that. This book examines Evidence Based Practices on topics of critical importance to otolaryngologists-head and neck surgeons. The evidence has been gathered and is presented by leaders in their respective fields. Topics cover evidence-based practice of: Management of Vertigo, Management of Adult Sensory Neural Hearing Loss, Cochlear Implantation, Reflux in Sinusitus, Balloon Dilation in Otolaryngology, Postoperative Care in Endoscopic Sinus Surgery, Functional Rhinoplasty, Sublingual Immunotherapy for Allergic Rhinitis, Adult Obstructive Sleep Apnea, Pediatric Obstructive Sleep Apnea, Pediatric Tonsillectomy, Management of Vocal Cord Paralysis, Management of Hoarseness, Endoscopic Skull Base Resection for Malignancy, Management of Glottic Cancer, Management of Thyroid Cancer, and Management of N0 Neck.
