What may be necessary to assess in patients with facials nerve palsy?

In patients with facial nerve palsy, assessing for lagophthalmos is particularly important because this condition refers to the incomplete closure of the eyelids. Lagophthalmos can result from weakness or paralysis of the facial muscles responsible for eyelid movement. This incomplete closure can lead to exposure of the cornea, which may result in dryness, irritation, or damage to the eye if not addressed.

Monitoring whether the patient can blink regularly is also relevant, but the presence of lagophthalmos is a more specific concern that directly relates to potential complications affecting ocular health. Evaluating visual acuity or inquiring about previous surgeries, while useful in broader assessments, do not directly address the immediate concerns posed by facial nerve dysfunction and its implications on eyelid function. Thus, recognizing and managing lagophthalmos becomes essential in the care of patients with facial nerve palsy to prevent further complications.
