Nasal obstruction after cervical sympathectomy: Horner's syndrome revisited.

Horner's syndrome (cervical sympathetic paralysis) typically includes ptosis, miosis, enophthalmos and facial anhidrosis. However, the effect of sympathetic denervation upon the nasal mucosa should be included as a prominent feature, since nasal obstruction is often the most disabling sequel. The anatomical, physiological, and historical basis is discussed and surgical management suggested.
