Dr. Matthew Clavenna is Board Certified in Otolaryngology and a fellowship trained Rhinologist with sub-specialty expertise in diagnosing and treating complex cases related to the nose, paranasal sinuses, and anterior skull base.

Dr. Clavenna continues to be at the forefront of surgical management of complicated sinus disease. He is among only a handful of specialists with advanced Rhinology training beyond residency serving Pinellas County.

As needed, he collaborates closely with other specialists, including neurosurgery and ophthalmology peers, to perform skull base and ophthalmologic surgeries through the nose and mouth, including pituitary tumor resection, CSF leak repairs, endoscopic powered dacryocystorhinostomy and endoscopic optic nerve and orbital decompressions.

Dr. Clavenna actively advocates for his patients, helping them to understand their treatment options and the best surgical approach for their disease and lifestyle. His extensive educational background and clinical training position him as an expert in his field.

 As a fellowship trained Rhinologist, I am in position to touch lives in a positive manner and help people of all ages resolve a wide range of complex health issues through in-clinic care and surgical procedures.  And my patient care philosophy is simple. My goal is always to develop a friendly rapport with patients and help educate them about their problems, so they can make well-informed decisions about their health. I treat patients with the same level of care and respect that I would extend to my own family. I take this position of trust and responsibility very seriously.


Dr. Clavenna trained in the renowned Rhinology and Skull Base Surgery Fellowship program at Vanderbilt University, considered a global “Center of Excellence” for the discipline. 

The fellowship is an intensive one-year program that combines clinical and surgical duties to equip physicians with the advanced skills to be a leader in rhinology and endoscopic skull base surgery.

Fellows participate in intensive clinical activities addressing the breadth of medical rhinology. Surgical cases include primary and revision sinus surgery, skull base and orbital pathology, and treatment of CSF leaks and encephaloceles.  A broad anterior skull base and pituitary experience includes the use of extended endoscopic approaches and complex reconstruction techniques collaboratively with neurosurgical colleagues. Endoscopic approaches to orbital pathology are also emphasized as part of a close collaborative effort with oculopastic surgery.

The Rhinology and Endoscopic Skull Base Surgery Fellowship program is also integrated with the Vanderbilt Allergy, Sinus and Asthma Partnership (VASAP), a joint venture, consisting of specialists in allergy/immunology, rheumatology, and pulmonary.  This provided Dr. Clavenna multi-layered training and opportunities to address patients with complex airway inflammatory diseases.
