What tests are done to diagnose the cause of sinus atresia?

The diagnosis of sinus atresia requires imaging and endoscopic examinations to clarify the cause. Common methods include CT scans, MRI and nasal endoscopy. Sinus atresia is usually caused by congenital developmental abnormalities, trauma, infection or tumors. The treatment method is surgical intervention or drug therapy according to the cause.

1. Imaging examination is an important means to diagnose sinus atresia. CT scan can clearly show the anatomical structure of the sinuses and help find bony atresia or soft tissue abnormalities. MRI is more suitable for evaluating soft tissue lesions, such as tumors or inflammation. These examinations can provide doctors with detailed lesion information and assist in formulating treatment plans.

2. Nasal endoscopy is another important diagnostic method. By inserting an endoscope into the nasal cavity, the doctor can directly observe the condition of the sinus opening and determine whether there is atresia or stenosis. Endoscopy can also be performed at the same time as a biopsy to clarify the nature of the lesion, such as whether it is a tumor or infection.

3. Congenital developmental abnormalities are one of the common causes of sinus atresia. During embryonic development, the sinus structure fails to form normally, leading to atresia. This condition usually requires surgical correction, such as sinusoplasty or sinuplasty, to restore normal ventilation function.

4. Trauma may also cause sinus atresia. After a blow to the nose or surgery, the structure of the sinuses may change, resulting in atresia. Treatments include surgical repair, such as sinus reconstruction, combined with drug therapy to prevent infection when necessary.

5. Infection and inflammation are another common cause of sinus atresia. Chronic sinusitis or fungal infection may cause blockage of the sinus opening. Treatment includes antibiotics or antifungal drugs. In severe cases, surgery is required to remove the lesions, such as sinus irrigation or sinus drainage.

6. Tumorous lesions may also cause sinus atresia. Benign or malignant tumors may compress or block the sinus opening. After diagnosis, treatment methods include surgical resection, radiotherapy or chemotherapy, and the specific plan needs to be formulated according to the nature of the tumor.

The diagnosis and treatment of sinus atresia require a combination of imaging examinations, endoscopic examinations and etiology analysis. Treatment methods include surgical intervention and drug therapy. The specific plan needs to be formulated based on the cause and condition. It is recommended that patients seek medical attention in a timely manner and be evaluated and treated by a professional doctor.
