ABSTRACT
ABSTRACT Penetrating middle ear injury may cause hearing loss, vertigo, or facial nerve injury, although facial nerve paralysis followed by head trauma is a rare condition. In this study, we report a case of a 3-year-old patient with delayed facial palsy on the left side that developed 4 days after an accidental tympanic membrane perforation caused by a cotton-tipped swab. Otoendoscopic examination revealed a perforation in the posterosuperior quadrant of the tympanic membrane. Audiometry revealed no hearing loss on the injured side, and eye movement examination did not reveal spontaneous or positional nystagmus. Pre- and postcontrast T1-weighted magnetic resonance imaging demonstrated high signal intensity along the tympanic portion of the fallopian canal, which suggested that hemorrhage within the facial canal may be a cause of delayed facial palsy. It can be assumed that traumatic injury at the dehiscent facial nerve in the tympanic portion caused hematoma within the fallopian canal, resulting in delayed facial nerve palsy.
