ABSTRACT
Temporal bone fractures after head trauma are divided into three groups; longitudinal fracture, transverse fracture and mixed fracture. The most common symptoms are hearing impairment, bloody otorrhea, loss of consciousness and facial nerve palsy. The early care of temporal bone fracture involves facial nerve palsy.
The authors report the clinical study of 6 cases of temporal bone fractures associated with facial nerve palsy.
Five cases were unilateral and one case was bilateral.
In 5 unilateral cases, 4 cases showed conductive hearing loss and 1 case was total deaf, and bilateral case showed conductive and sensorineuralhearing losses.
In 5 unilateral cases, 1 case showed longitudinal fracture, 3 cases were transverse and 1 case was mixed, and bilateral case showed longitudinal fractures.
In 5 cases, facial palsy occurred immediately after the trauma and 1 case showed delayed onset.
The degree of facial palsy was grade III in 1 case, grade IV in 4 cases involving bilateral case, and grade V in 1 case.
Nerve decompressions were performed in 3 cases including a bilateral case, hypoglossal-facial crossover in 1 case, and in 2 cases medical therapy was done.
There were complete recoveries in 2 cases, partial recoveries in 2 cases, and no change in 1 case.
