Besides muzzle deviation, what ocular sign is described as a classic sign of temporohyoid osteopathy?

• A. Epiphora
• B. Red eye
• C. Dry eye
• D. Cloudy cornea

Answer: (C)

Temporohyoid osteopathy can press on the nerves as they pass the skull base, especially the facial nerve. When facial nerve function is affected, eyelid closure and the blink reflex weaken, and parasympathetic input to the lacrimal gland can be reduced. That leads to decreased tear production and a dry ocular surface. Dry eye, or keratoconjunctivitis sicca, is a classic ocular sign seen with this condition, often with exposure-related keratitis as the eye doesn’t stay adequately lubricated. Other signs like tearing, redness, or a cloudy cornea can occur secondarily, but dryness is the hallmark alongside muzzle deviation.
