For which condition is increased tear flow noted as a symptom?

Increased tear flow is indeed a noted symptom in Bell's palsy. This condition involves sudden weakness or paralysis of the facial muscles, typically on one side of the face, due to inflammation of the facial nerve (cranial nerve VII). One of the notable effects is the disruption of normal tear production and drainage mechanisms. When the facial nerve is affected, it can lead to decreased ability to blink and a lack of proper nerve signals to the lacrimal glands, possibly resulting in both excessive tearing and dry eyes (due to impaired eyelid closure).

Furthermore, this condition can lead to a variety of symptoms, including changes in taste, increased sensitivity to sound, and facial numbness. The involvement of lacrimal glands and the facial nerve in Bell’s palsy makes increased tear flow a significant characteristic, especially when differentiating this condition from other types of headaches or sinus issues.
