Southern California Sinus Institute is the premier sinus center serving the greater Los Angeles, San Fernando Valley and Thousand Oaks areas. Southern California Sinus Institute specializes in the medical and surgical treatment of patients with various nasal and sinus disorders including nasal obstruction, environmental allergies, acute and chronic sinusitis, nasal polyps, and sinus headaches. Alen N. Cohen, M.D., F.A.C.S., a board-certified Head and Neck Surgeon and recognized leader in the field, is founder and director of the Southern California Sinus Institute. Dr. Cohen developed this center due to a special need that he noticed among patients who would at times travel long distances to see him for their complex problems. These patients were uniformly looking for a physician who focused on the comprehensive management of their problems and offered both medical and surgical options to treat their condition. Due to this special need and with his extensive training and passion for the treatment of nasal and sinus pathology, he developed the Southern California Sinus Institute in 2009. This center focuses on the multitude of innovative medical and surgical treatment options available to patients with nasal and sinus disorders. He has personally pioneered a breakthrough procedure in the treatment of chronic sinusitis, nasal polyps and sinus headaches termed Minimally Invasive Image Guided Sinus Surgery (MIGSS)™. He also routinely performs Balloon Sinuplasty™ to treat select patients with acute and chronic sinusitis. Nonetheless, what stands out most about Dr. Cohen is his compassion and professionalism in the treatment of his patients. This quality is not only expressed by the multitude of patients he has treated for years but by the numerous physicians who refer him patients regularly and come to see him as patients themselves.
