Welcome! The Sinus & Nasal Institute of Florida, P.A. (SNI) is a center of excellence that sub-specializes in the medical and surgical care of patients with nasal and paranasal sinus disorders (rhinology). Our director, Dr. Donald C. Lanza, is an internationally recognized, board certified otolaryngologist. During the past 15 years, his clinical focus has been in rhinology and the development of minimally invasive (endoscopic) sinus surgery techniques. Although Dr. Lanza is a sub-specialist, he also treats children and adults with general ears, nose, and throat problems.

Whether you have nasal blockage, chronic rhinosinusitis, inhalant allergies, cerebrospinal fluid drainage, or even a sinus tumor, we strive to give you up-to-date care with current diagnostic and therapeutic technology. As a result, the Sinus & Nasal Institute of Florida, P.A. is well positioned to offer you superior subspecialty ears, nose and throat care. For more information on rhinologic healthcare problems that we treat please go to “Healthcare Disorders Diagnosed & Treated”.
