Can left maxillary sinusitis heal on its own?

Whether acute left maxillary sinusitis can resolve spontaneously usually depends on specific factors such as the underlying cause, severity, and duration of symptoms. If symptoms persist or worsen, prompt medical attention is recommended. Detailed analysis is as follows:

In cases of acute left maxillary sinusitis triggered by a common cold, if symptoms are mild and the patient is in good general health, spontaneous recovery is possible. In such cases, the inflammation is typically mild and sinus drainage remains unobstructed. The body's immune system can gradually eliminate the pathogens, and symptoms such as nasal congestion and runny nose usually improve within 1–2 weeks. Adequate rest and increased fluid intake during this period can support recovery.

Chronic left maxillary sinusitis or severe acute cases generally do not resolve without treatment. Chronic inflammation often results from recurrent episodes that lead to mucosal thickening and impaired sinus drainage, with symptoms lasting longer than 12 weeks. Patients with severe acute sinusitis may experience intense headaches, purulent nasal discharge, and fever. Without intervention, the infection may spread, necessitating medication or surgical treatment to control the condition.

In daily life, regularly rinsing the nasal cavity with saline solution can help maintain sinus patency. Avoid exposure to irritants such as dust and pollen, and wear a mask when outdoors. Maintain a light, easily digestible diet rich in vitamins. Ensure sufficient sleep, avoid excessive fatigue, and strengthen overall immunity. Seek medical care promptly if symptoms worsen.
