Diagnostic Tests at Our Center

ENT centers offer a range of diagnostic tests to assess and diagnose various conditions related to the ear, nose, and throat. Here are some common diagnostic tests that may be performed at Nepal ENT center:

  1. Audiometry (PTA): This test evaluates your hearing abilities. It involves wearing headphones and listening to tones of different frequencies and volumes. You are asked to indicate when you hear the tones, allowing the audiologist to assess your hearing thresholds.
  2. Tympanometry: Tympanometry measures the movement of the eardrum in response to changes in air pressure. It helps assess the condition of the middle ear and can identify issues such as fluid accumulation, eardrum perforations, or problems with the Eustachian tube.
  3. Brainstem Evoked Audiometry Response (BERA): BERA is a diagnostic test used to evaluate the hearing function and assess the integrity of the auditory pathway, from the ear to the brainstem. It is particularly useful in assessing hearing in infants, young children, and individuals who may have difficulty responding to traditional hearing tests. During a BERA test, small electrodes are placed on the scalp and earlobes to detect and record electrical activity generated by the auditory pathway in response to sound stimuli. The individual undergoing the test listens to a series of clicks or tones through headphones or speakers. The electrodes pick up the electrical responses from the auditory nerve and brainstem as they travel to the brain. The BERA test measures the time it takes for the electrical responses to occur at different stages of the auditory pathway. It can help determine the presence and degree of hearing loss, identify the type and site of hearing impairment, and differentiate between conductive and sensorineural hearing loss. The results of the BERA test are presented in the form of a graph called an audiogram. This graph shows the individual's hearing thresholds at different frequencies and can assist in diagnosing hearing disorders and planning appropriate treatment options. A BERA test is typically performed by an audiologist or a healthcare professional specialized in audiology. It is a safe and non-invasive procedure, although the placement of the electrodes may cause slight discomfort. The test is usually conducted in a soundproof room or booth to ensure accurate results. If you or your child are experiencing hearing difficulties or have concerns about auditory function, consulting with an ENT specialist or audiologist is recommended. They can determine if a BERA test is necessary and guide you through the process, interpretation of results, and any further steps that may be required.
  4. Otoacoustic Emissions (OAEs): OAEs are used to assess the function of the inner ear, specifically the cochlea. This test measures the sound waves produced by the inner ear in response to external stimuli. It helps determine the presence or absence of hearing loss.
  5. Videonystagmography (VNG): VNG is a test that evaluates the function of the vestibular system, which contributes to balance and spatial orientation. It involves wearing goggles equipped with cameras to track eye movements while you perform specific head and body movements.
  6. Nasal Endoscopy: Nasal endoscopy is a procedure where a thin, flexible tube with a light and camera (endoscope) is inserted through the nostrils to examine the nasal passages, sinuses, and throat. It allows the ENT specialist to visualize any abnormalities or blockages.
  7. Flexible Laryngoscopy: This procedure involves passing a thin, flexible tube with a camera (laryngoscope) through the nose or mouth to examine the larynx (voice box) and vocal cords. It helps assess vocal cord function, vocal cord lesions, and other throat-related conditions.
  8. CT Scan/MRI: In certain cases, an ENT center may refer you to perform imaging studies such as computed tomography (CT) scans or magnetic resonance imaging (MRI) or radioactive scan or even a contrast x-ray. These tests provide detailed images of the structures within the head and neck region and can aid in diagnosing conditions like sinusitis, tumors, or anatomical abnormalities.

It's important to note that the specific tests conducted will depend on the individual's symptoms, medical history, and the suspected condition. Your ENT specialist will determine which tests are appropriate for your case and provide you with the necessary information and guidance throughout the diagnostic process.
