What symptoms are indicative of maxillary sinusitis?

Maxillary sinusitis often presents with a range of specific symptoms that are closely tied to the anatomy and function of the maxillary sinuses. Post-nasal discharge is a hallmark of maxillary sinusitis, as the inflammation and infection can cause mucus to drain from the sinuses into the throat. This can lead to a feeling of discomfort and irritation.

Headache is also a common symptom, usually felt in the cheek or above the upper teeth due to the pressure and inflammation of the sinus cavity. The pain may often be exacerbated by bending forward or during chewing because of the proximity of the maxillary sinuses to the roots of the upper molars, which can indeed cause referred tooth pain or toothache even when the primary issue is a sinus infection.

While other symptoms from different choices could occur in various sinus conditions, the combination of post-nasal discharge, headache, and toothache is particularly characteristic of maxillary sinusitis, making this the most indicative choice for the condition.
