The Ear Foundation of Santa Barbara is a non-profit organization based in California that was founded on July 2, 1979 because of the mutual concern of Joseph Di Bartolomeo, M.D., and the late Burl Ives, about the prevalence of hearing disorders in the community.

The interest of the Ear Foundation is primarily in public education, medical training, and research related to diseases of the ear. This includes hearing loss, equilibrium disorders and tinnitus. More recently, great strides have been made in healing the Patulous Eustachian Tube.

The Ear Foundation is dedicated to the investigation of diseases affecting hearing or equilibrium and to a better understanding of such disorders through professional and public education.

Our goal is to bring better hearing to all. One out of every 12 individuals in our community suffers from some type of hearing loss. It affects both sexes and all ages...when present at birth it interferes with the development of speech; in children it inhibits proper emotional and social growth; in young adults hearing loss limits participation as vital members of our working community; in the mature or elderly, it can gradually cause isolation from daily involvement in life's activities - a dreary and lonely prospect.

The Ear Foundation recognizes that good hearing and equilibrium are essential in the pursuit of a richer family life, a broad area of vocations, and independence in work and retirement.

The Clinical Study of the Patulous Eustachian Tube

The clinical study is a double-blind, phase III, F.D.A. study of an Investigational New Drug (IND # 40,202) for severe patulous Eustachian tube. The medication is an Orphan Drug (# 96-988), which is an F.D.A. classification for medication for rare disorders. While semi-patulous Eustachian tube disorder is uncommon, the patulous eustachian tube (severe form) is rare.

Because he suffered from the symptoms of autophony, amphoria and crackling of the ears, Dr. Di Bartolomeo researched the literature to find an answer to this rare disorder. While discovering the cause of these symptoms, he began to research a safe medical treatment. These findings were published in various otologic publications to encourage physicians to think of the patulous eustachian tube condition when a patient has a complaint of a 'plugged ear,' are disturbed by their own voice or breath sounds, and the ear examination by the specialist and the tympanogram test are completely normal. This is the time to suspect a PET. Initial clinical study results were published in "A New Medication to Control Patulous Eustachian Tube Disorder," American Journal of Otolaryngology 18:323-327. Two clinical studies followed and the final "phase III" study has begun.

The Drug Free, Vitamin Product

The first FDA formula to treat PET was a medication.  As a result of our research project, a drug free novel composition was developed to be delivered in the form of nose drops.  The pure nutrient vitamin supplement, PatulEND®, is the only FDA orphan designated approved product (#96-988) that qualifies for their exclusive designation as the treatment of the rare disorder of Patulous Eustachian Tube presenting with autophony, also known as "DiBartolomeo's Syndrome".

The method of administration is critical to its effectiveness. The patients' head is tilted 90 degrees toward the effected side so that the drops reach the Eustachian tube opening. The patient sniffs the drops back to the Eustachian tube opening. Some patients may experience a stinging sensation.  Please refer to our PatulEND® directions for use instructions, for further details.
