Diagnostic Tools

Audiograms can be performed by pediatric otolaryngologists to reliably diagnose hearing in young children through adults. This test is designed to be fun and interactive for children while providing accurate diagnostic information. 

Otoacoustic emissions, or OAEs, is a very quick screening method to determine whether the cochlea, or organ of hearing, is functioning appropriately. This can help determine whether infants have normal hearing. 

Auditory brainstem response, or ABR, measures brainwave response to sound. 
This test is done under light sedation and can provide an excellent representation of hearing in young children or uncooperative patients. 

Tympanogram is a test which measures whether fluid is present behind the eardrum by placing a simple probe in the ear. 

Tympanostomy with tube insertion (PET) is a minor surgery often performed with patients asleep in the operating room, where a small tube is inserted directly through the eardrum to remove middle ear fluid. This is most commonly performed for recurrent infections or persistent middle ear fluid. 

Tympanoplasty is a delicate procedure performed to repair holes in eardrums and to repair or revise the middle ear bones. This can be done through an incision either through the ear canal or behind the ear. 

Mastoidectomy is a surgery performed by drilling behind the ear in which the infected bone, the mastoid bone, behind the ear is opened up to remove infected tissue or cholesteatoma. This is often done in conjunction with a tympanoplasty to repair the eardrum and ear bones. 

For the cochlear implantation procedure, a small wire is inserted through the mastoid directly into the cochlea. This is connected with a small implant buried directly under the skin. This allows soundwaves to be converted directly to electrical energy to stimulate the cochlea. 

A bone anchored hearing aid is a surgically implanted device in which a small screw is placed directly into the skull. The attached hearing device then directly stimulates the skull and cochlea resulting in improvement in hearing.
