Isolated Unilateral Soft Palate Palsy Following Tonsillopharyngitis Caused by Epstein-Barr Virus Infection.

Soft palate palsy with or without pharyngeal or laryngeal paralysis or facial palsy has been described in the literature fewer than 40 times. Of these cases, isolated unilateral soft palate palsy (occurring without any other neurologic manifestation) has been rare. Most cases of isolated soft palate palsy were termed idiopathic in the past. In a few cases, a concomitant viral infection such as varicella zoster, herpes simplex, measles, and coxsackie A9 was diagnosed. We describe a case of isolated soft palate palsy, following a pharyngotonsillitis caused by Epstein-Barr virus. This viral infection has been linked in the past with bilateral facial nerve palsy and radial nerve palsy. Our patient recovered spontaneously over a period of 1 month.
