RESUMO
Patients suffering from abducent nerve palsy are usually primary seen by a conservative medical Specialist. In most cases the ENT specialist is secondary involved for treatment. In the majority of cases abducent nerve palsy is a temporary symptom associated with neurologic or vascular diseases. Rarely inflammation, neoplasm or fracture of the skull base cause this symptom and lead to an intervention done by the ENT surgeon. This case series describes retrospectively the abducent palsy seen through the eyes of an ENT surgeon. From 2008 to 2011 15 patients suffering from abducent nerve palsy. One patient suffering from a temporal bone fracture has been treated conservatively while 14 patients needed surgery. 6 patients had a complicated inflammation of the skull base. In 7 patients skull base neoplasms were found in endoscopic surgery. In one case the underlying pathology remained unclear. 2 third of the patients that suffered from complications of inflammatory diseases completely recovered after a combined operative and conservative therapy. The patients who suffered from neoplasms of the skull base partially recovered in only one third, none, achieved full recovery. The patient with the temporal bone fracture achieved a partial recovery after 3 months. If the leading symptom of abducent palsy is caused by a severe extracranial inflammation, neoplasm or trauma an experienced skull base surgeon is mandatory. The recovery rate of abducent palsy in our case series was 60 %. The prognosis of abducent palsy in skull base inflammation is much better compared to patients with skull base neoplasm.
