    Nasal and Throat Examination with an Endoscope (Nasal Endoscope)

    Nasal and throat examination with an endoscope (Nasal Endoscope) involves the inspection of the inside of the nasal cavity and the throat area behind the nasal passages using a small camera. Both the doctor and the patient can view the images on a high-resolution display simultaneously, allowing for the diagnosis of various problems in the nasal cavity, such as nosebleeds, nasal congestion, chronic colds, and the detection of pathologies behind the nasal cavity, which is the area most commonly associated with cancer from an early stage, enabling appropriate treatment thereafter.


    Examination of the Vocal Cords and Upper Windpipe with a Fiberoptic Laryngoscope

    Examination of the vocal cords and the upper part of the windpipe with a fiberoptic laryngoscope involves inspection of the area around the vocal cords and lower throat using a small camera. This area often presents various problems such as hoarseness, chronic sore throat, difficulty breathing, choking on water, and food, etc.


    The use of a small camera for the examination allows for accurate diagnosis of different problems without any pain.

    • Ear Examination with a Microscope involves the use of the same type of microscope used for surgery, which provides sharp and highly detailed three-dimensional images. This allows for effective diagnosis and treatment of conditions such as hearing loss, external and middle ear infections.
    • Hearing Tests (Audiogram and Tympanogram) are tests to assess the condition of hearing and the function of the middle and inner ear, in cases where there are problems such as hearing loss, ringing in the ears, ear infections, vertigo, etc.
    • Auditory Brainstem Response Examination is a test for the electrical signals of hearing from the inner ear to the brainstem, which can be used to assess hearing in young children who are likely to have hearing problems or to diagnose tumors of the auditory nerve from an early stage in those with hearing loss or balance disorders, possibly due to tumors in that area.
    • Chronic sore throat, difficulty swallowing, lumps in the mouth, throat If these symptoms persist for more than 2 weeks, it may not be a common infection but could be early symptoms of a tumor or cancer. Detailed examinations including special tests such as endoscopy, special X-rays can reveal the pathology from an early stage.
    • Hoarseness is caused by the vocal cords within the voice box not closing tightly, which can result from inflammation of the voice box, tumors on the vocal cords. A small camera can be used to inspect the condition of the vocal cords accurately and painlessly. Therefore, if hoarseness persists for more than 2 weeks, it is advisable to see a doctor promptly.
    • Bloody sputum may result from inflammation or tumors, cancer within the nasal cavity, behind the nasal passages, throat, voice box, and the upper part of the esophagus. If you have bloody sputum for several days consecutively, or frequently without a clear cause, it is advisable to consult a doctor promptly.
