What causes inflammation of the right frontal sinus?

Under normal circumstances, inflammation of the right frontal sinus may be caused by abnormalities in nasal structure, decreased resistance due to excessive fatigue, spread of acute rhinitis, allergic rhinitis, obstruction from nasal polyps, and other factors. It is recommended to seek timely medical attention, identify the underlying cause, and receive symptomatic treatment under a doctor's guidance. The specific analysis is as follows:

1. Abnormal nasal structure: Deviation of the right nasal septum or hypertrophy of the middle turbinate can block the opening of the right frontal sinus, leading to mucus retention and subsequent inflammation. Avoid forceful nose-blowing in daily life. Nasal irrigation can help clear secretions; severe cases should seek medical evaluation for possible structural correction.

2. Decreased resistance due to overexertion: Long-term sleep deprivation and high stress levels weaken immunity, making it easier for bacteria to invade the right frontal sinus and cause inflammation. Maintain regular作息 (sleep-wake cycles), ensure 7–8 hours of sleep per night, eat a balanced diet rich in protein and vitamins, and engage in moderate exercise to strengthen immunity.

3. Spread of acute rhinitis: A cold may lead to acute rhinitis, with inflammation spreading through the nasal passages to the right frontal sinus, causing mucosal congestion and inflammation. Patients may use medications such as mometasone furoate nasal spray, cefuroxime axetil tablets, and Lianhua Qingwen capsules according to medical advice.

4. Allergic rhinitis-induced inflammation: Exposure to allergens causes swelling of the mucosa in the right nasal cavity, blocking the frontal sinus opening and triggering inflammation, often accompanied by nasal itching and sneezing. Medications such as cetirizine hydrochloride tablets, budesonide nasal spray, and montelukast sodium tablets may be used under medical supervision.

5. Nasal polyp obstruction: Enlargement of nasal polyps in the right nasal cavity may compress and block the opening of the right frontal sinus, preventing drainage of secretions and leading to inflammation. Initial treatment may include fluticasone propionate nasal spray, prednisone tablets, and azithromycin capsules as directed by a physician. If ineffective, endoscopic nasal polypectomy may be performed to remove the polyps and reopen the frontal sinus.

In daily life, stay warm to prevent colds, and wear a mask when going out during hazy or high pollen seasons. Keep indoor air moist and avoid dry environments that may irritate the nasal passages. Regularly rinse the nasal cavity with saline solution to reduce accumulation of bacteria and allergens.
