Dr. Otávio Henrique Vilas Boas Fantin has been a physician since 2013 and is an Otolaryngologist and Laryngology specialist dedicated to the surgical treatment of voice, swallowing, and airway disorders.
He completed his residency in Otolaryngology at Santa Casa de Curitiba / Hospital Universitário Cajuru – PUCPR.

He currently sees patients at Centro de Diagnóstico Otorrinolaringológico (CDO) in Florianópolis, Santa Catarina, and performs surgeries at the city’s leading hospitals.

Voice and Laryngeal Surgery Focused on Results and Safety
Treatment begins by listening carefully to what each patient tells us. Every person carries a unique history, concerns, and life experience. That is why we believe treatment must be individualized. Our practice is grounded in up-to-date scientific evidence and the use of modern, minimally invasive surgical techniques whenever indicated. The goal is to preserve voice and breathing function while improving the quality of life of those who seek our care.
In addition to his clinical practice, Dr. Otávio serves as a speaker at medical courses and conferences throughout Brazil and maintains continuous training at leading national and international centers of excellence, bringing patients the most advanced approaches available in the treatment of laryngeal disorders.
