What tests are done to diagnose sinus atresia?

The diagnosis of sinus atresia requires a combination of imaging and endoscopic examinations. Common examination methods include CT scans, MRI, nasal endoscopy, and sinus X-rays. These examinations can clearly show the structure of the sinuses and the location of atresia, helping doctors to make an accurate diagnosis.

1. CT scan is the preferred method for diagnosing sinus atresia. CT can provide high-resolution cross-sectional images, clearly showing the anatomical structure of the sinuses and the location of atresia. Through CT scans, doctors can determine the scope and degree of atresia, providing a basis for subsequent treatment. CT scans are non-invasive and rapid, and are commonly used clinical examination methods.

2. MRI examination has a higher resolution for soft tissue and is suitable for evaluating inflammation or tumors associated with sinus atresia. MRI can clearly show the lesions of the sinus mucosa and the involvement of surrounding tissues, which is of great significance for the diagnosis of complex cases. MRI has no radiation and is suitable for repeated examinations or for special populations.

3. Nasal endoscopy is an effective method to directly observe sinus atresia. Through the endoscope, the doctor can visually see the internal conditions of the nasal cavity and sinuses and evaluate the location and degree of atresia. Endoscopic examination can be combined with biopsy to obtain tissue samples for pathological examination to further clarify the cause. Endoscopic examination is minimally invasive and can be performed in an outpatient clinic.

4. Sinus X-ray is a traditional examination method. Although the resolution is low, it is still valuable for preliminary screening of sinus atresia. X-rays can show the general outline and gasification of the sinuses, and provide a reference for the diagnosis of simple cases. X-rays are easy to operate and low in cost, making them suitable for use in primary hospitals.

The diagnosis of sinus atresia requires a combination of multiple examination methods, and the appropriate examination method should be selected according to the patient's specific situation. CT scan and nasal endoscopy are commonly used diagnosis methods, and MRI and X-rays can be used as supplementary examinations. Accurate diagnosis helps to develop a reasonable treatment plan and improve the patient's quality of life.
