Diphtheria is a vaccine-preventable illness caused by exotoxin-producing strains of Corynebacterium diphtheria. Diphtheria is clinically considered to be a biphasic illness with initial symptoms of low-grade fever, sore throat, neck swelling, nasal twang, and usually ipsilateral palatal paralysis followed by diphtheric polyneuropathy. A 11-year girl presented with nasal twang followed by postdiphtheric palatal palsy was treated with palatal exercise for improving nasal twang and noticeable change was found in quality of phonation by treatment with palatal exercise.
