CT of the paranasal sinuses

CT of the paranasal sinuses is the most reliable, safe, non-invasive, painless method for examining the cavities of the maxillary and frontal sinuses, ethmoid labyrinth, sphenoid bone using x-rays. The diagnostic method for a short period of time, “making” very thin sections of the organ, allows you to “see” the structural features, as well as all pathological processes that occur in the sinuses. In a three-dimensional layered image, the bones of the skull and sinus are visible. Time: 5 minutes, with contrast – up to 30 minutes. Preliminary preparation: needed when using contrast. Contraindications: no contrast – no, with contrast – yes. Restrictions: allergy to iodine, young children, pregnancy, weight more than 150kg, kidney failure Report preparation time: 30 minutes. The price of CT of the paranasal sinuses is 1000 UAH, 2400 UAH – with a bolus

  1. • thoroughly study and evaluate the condition of the maxillary and frontal sinuses and lacrimal ducts;
  2. • track changes in the mucous membrane;
  3. • detect the presence of blood, pus, fluid, inflammation (frontal sinusitis, sinusitis, ethmoiditis, chronic sinusitis), organ atrophy;
  4. • identify cysts, polyps, neoplasms, trauma, curvature of the nasal septum, developmental abnormalities;
  5. • identify foreign bodies in the sinuses and nasal cavity.

How is the CT scan of the paranasal sinuses

The patient is placed on the mobile table of the tomograph face down, with a special device, the chin is lifted, the head is fixed to ensure complete immobility. Only the patient is in the office. Communication with the doctor takes place through a feedback device. The table begins to move through a rotating scanner, slight crackles and buzzing are heard. The doctor through the speakerphone asks you to hold your breath. The study does not bring the patient any inconvenience. The session is quick, easy, painless. The received pictures are sent to a computer in which they are processed by a special program. Results – a three-dimensional image is displayed on the monitor screen.

The introduction of a contrast medium (bolus)

A study with a contrast agent is prescribed for some patients for better “visibility” of the tissues, structures and blood vessels of any area of ​​the examined organ and their more detailed study. An injection of an iodine-containing bolus is performed by an anesthetist intravenously. Reaction to contrast: heat, slight tingling (“goosebumps”) in the body. If it is difficult to breathe, the head becomes heavy, it is necessary to tell the doctor about this (in order to respond in time to a possible allergic reaction). The contrast agent is completely excreted from the body during the day. Indications for bolus administration:
  1. • suspicion of injuries, neoplasms;
  2. • to assess the state of ENT organs in the treatment of neoplasms;
  3. • to exclude relapses.
Patients suffering from allergic reactions should report this before starting the CT procedure with contrast.

What are the risks of having a CT scan of the sinuses?

The procedure of CT examination does not pose any threat to the health of the patient. Our office is equipped with the most advanced equipment providing a minimum dose of radiation. A person receives the same dose of radiation in a short period of ordinary life in the city. In order not to harm the unborn child, the woman, before starting the CT scan, is obliged to inform her doctor of her “interesting position”, pregnancy. Special precautions will be taken.

How to prepare for a CT scan of the sinuses of the nose

Preparation for a CT scan of the paranasal sinuses is only necessary if contrast is needed. You will not have to eat for 6 hours before the session. The patient should be dressed in comfortable clothes, it is necessary to take off everything metallic (jewelry, glasses, hairpins, dentures). Information about diseases, especially chronic ones, taking medications, possible allergic reactions, pregnancy should be brought to the radiologist.

Getting Results

After the procedure, the radiologist studies, analyzes and describes the images. The patient receives: digital copies of the pictures, their description by a radiologist with a signature and seal. Our CT-cabinet has a program for automatic image quality control. An accurate detailed diagnosis of the paranasal sinuses allows you to identify inflammation, pathology, and get rid of a diagnostic biopsy.
