The voice is not affected in:: (A) Unilateral abductor palsy, (B) Unilateral adductor palsy, (C) B/L superior laryngeal palsy, (D) Total adductor palsy
Answer is A. In U/L abductor palsy, the affected vocal cord assumes a median or paramedian position. The other is normal so one third patients are asymptomatic while others may have some voice change.
