Diagnostic & Audiology Services – Common Treatments
1. Pure Tone Audiometry (PTA)
Pure Tone Audiometry is a standard hearing test that evaluates hearing sensitivity across different frequencies. It helps determine the degree and type of hearing loss in patients. This painless, non-invasive test is essential for diagnosing hearing impairment and planning effective treatment options like hearing aids or cochlear implants.
2. Tympanometry
Tympanometry assesses the movement of the eardrum and middle ear function. It helps detect fluid in the middle ear, eardrum perforations, and Eustachian tube dysfunction. This simple diagnostic tool provides vital information about ear health, especially in children with frequent ear infections or suspected hearing loss.
3. Otoacoustic Emissions (OAE)
Otoacoustic Emission testing checks the function of the outer hair cells in the inner ear. It is commonly used for newborn hearing screening and early detection of hearing issues. The test is quick, safe, and highly effective in identifying hearing problems at an early stage.
4. Brainstem Evoked Response Audiometry (BERA/ABR)
BERA or ABR evaluates the auditory nerve pathways from the inner ear to the brainstem. It is especially useful for diagnosing hearing in newborns, children, or patients who cannot respond during routine hearing tests. This test also helps detect nerve-related hearing disorders and neurological problems.
5. Speech Audiometry
Speech audiometry measures the ability to detect and understand speech at various loudness levels. It complements pure tone testing and provides valuable insights into how well patients can communicate in daily life. This test helps audiologists recommend appropriate rehabilitative strategies like hearing aids or auditory training.
6. Auditory Steady-State Response (ASSR)
ASSR is an advanced electrophysiological test that estimates hearing thresholds objectively. It is particularly useful for infants or individuals who cannot cooperate in traditional hearing tests. The test records brain responses to sound stimuli, helping in precise diagnosis and planning for hearing aids or cochlear implants.
7. Video Otoscopy
Video otoscopy provides a magnified and detailed view of the ear canal and eardrum. The live video display helps both doctor and patient understand ear-related issues such as infections, wax buildup, or perforations. It is a valuable diagnostic tool and enhances patient awareness and involvement in care.
8. Tinnitus Evaluation & Management
Specialized tests assess the severity, frequency, and impact of tinnitus (ringing in the ears). Audiologists use questionnaires, sound matching, and masking techniques to evaluate the condition. Proper diagnosis allows the creation of customized management plans, which may include sound therapy, counseling, or hearing devices for relief.
9. Hearing Aid Trial & Fitting
After a thorough diagnosis, patients undergo a trial of suitable hearing aids. This service includes selecting the right device, customizing settings, and counseling on usage. Regular follow-ups ensure maximum benefit. Proper fitting and adjustment greatly improve hearing outcomes and enhance quality of life for hearing-impaired patients.
10. Cochlear Implant Evaluation
Cochlear implant candidacy is assessed through a series of diagnostic tests, including audiometry, speech perception, and imaging. The evaluation determines if a patient with severe or profound hearing loss will benefit from the implant. This comprehensive process ensures the best outcomes for restoring hearing ability.
Diagnostic & Audiology Services – Common Ailments
1. Hearing Loss
A condition where patients experience reduced ability to hear sounds, ranging from mild to profound. Causes may include aging, noise exposure, infections, or genetic factors. Accurate diagnosis using audiometry helps determine whether it is conductive, sensorineural, or mixed, ensuring timely treatment like hearing aids, implants, or medical management.
2. Tinnitus
A persistent ringing, buzzing, or hissing sound in the ears without an external source. It may result from ear infections, noise exposure, or hearing loss. Diagnostic tests like audiometry and tympanometry help identify underlying causes. Treatments include sound therapy, hearing aids, and counseling for managing discomfort and improving quality of life.
3. Vertigo and Balance Disorders
Vertigo is a sensation of spinning or imbalance, often linked to inner ear dysfunction. Causes may include BPPV, Meniere’s disease, or vestibular neuritis. Audiology tests like VNG and balance assessments identify the source. Proper diagnosis guides treatments, including vestibular rehabilitation therapy, medications, or surgical interventions to restore stability and comfort.
4. Auditory Neuropathy Spectrum Disorder (ANSD)
A rare hearing condition where sound enters the inner ear normally but signals fail to transmit properly to the brain. Patients often have difficulty understanding speech. Diagnosed through ABR and OAE tests, it may require hearing aids, cochlear implants, or auditory training for improved communication and sound perception.
5. Otitis Media with Effusion (OME)
A condition where fluid accumulates behind the eardrum without infection, commonly seen in children. It often causes muffled hearing and speech delays. Diagnosis includes tympanometry and audiometry. Early detection is crucial to prevent permanent hearing loss. Treatments range from watchful waiting to ventilation tube insertion, depending on severity and persistence.
6. Meniere’s Disease
A chronic inner ear disorder characterized by vertigo, fluctuating hearing loss, tinnitus, and ear fullness. The cause is thought to be abnormal fluid buildup in the inner ear. Diagnosis involves audiometric and vestibular tests. Management includes dietary changes, medications, and in severe cases, surgical options to reduce symptoms and preserve hearing.
7. Noise-Induced Hearing Loss (NIHL)
Prolonged exposure to loud sounds damages inner ear structures, leading to permanent hearing loss. Common among workers in noisy environments or due to excessive headphone use. Diagnosis with pure-tone audiometry confirms the condition. Preventive counseling, hearing protection devices, and hearing aids play an essential role in management and rehabilitation.
8. Congenital Hearing Loss
Hearing impairment present at birth due to genetic factors, maternal infections, or birth complications. It significantly affects speech and language development if undetected. Newborn hearing screening (OAE/ABR) allows early identification. With timely use of hearing aids, cochlear implants, and speech therapy, affected children can achieve near-normal communication and development.
9. Sudden Sensorineural Hearing Loss (SSNHL)
A rapid, unexplained loss of hearing in one ear occurring within 72 hours. Causes may include viral infections, vascular problems, or autoimmune conditions. Early diagnosis through audiometric testing is crucial. Prompt treatment with corticosteroids and supportive therapies improves the chances of recovery and helps prevent permanent hearing loss.
10. Acoustic Neuroma (Vestibular Schwannoma)
A benign tumor on the auditory nerve causing hearing loss, tinnitus, and imbalance. Symptoms progress slowly, often misdiagnosed initially. Diagnosis involves audiometry, ABR, and MRI scans. Early detection ensures effective treatment, including observation, radiosurgery, or surgical removal. Proper management prevents complications and helps preserve hearing and neurological functions.
