Bottom Line: Symptoms persisted despite rehabilitation.Various laboratory work up with magnetic resonance image showed no abnormal lesions.Two years after surgery patient showed complete recovery of unitaleral soft palate palsy.

ABSTRACT
Microvascular decompression is a very effective and relatively safe surgical modality in the treatment of hemifacial spasm. But rare debilitating complications have been reported such as cranial nerve dysfunctions. We have experienced a very rare case of unilateral soft palate palsy without the involvement of vocal cord following microvascular decompression. A 33-year-old female presented to our out-patient clinic with a history of left hemifacial spasm for 5 years. On postoperative 5th day, patient started to exhibit hoarsness with swallowing difficulty. Symptoms persisted despite rehabilitation. Various laboratory work up with magnetic resonance image showed no abnormal lesions. Two years after surgery patient showed complete recovery of unitaleral soft palate palsy. Various etiologies of unilateral soft palate palsy are reviewed as the treatment and prognosis differs greatly on the cause. Although rare, it is important to keep in mind that such complication could occur after microvascular decompression.

Figure 4: Follow up endocopic evaluation showing symmetric and mobile vocal cord movement within normal limits (A), and complete and symmetric valo closure showing normalized vagus nerve function (B).

Mentions: Patient visited our out-patient for a follow up in postoperative 2 years. Endoscopic examination revealed normalized soft palate palsy and no abnormality in the vocal cord mobility (Fig. 4). However, patient's subjective difficulty of speech still persisted and we decided to observe her symptoms for any changes in the future.
