Facial paralysis during air travel: case series and literature review.

OBJECTIVE We report three cases of recurrent, unilateral facial palsy associated with air travel. METHOD The three cases are presented, along with a brief literature review concerning barotrauma and its association with air travel and facial palsy. RESULTS All three patients experienced unilateral facial paralysis during air travel, accompanied by additional symptoms which varied between cases. Symptoms resolved spontaneously in all cases. Two patients received ventilation tube insertion to prevent further recurrence. Computed tomography scanning revealed no bony defect in two patients, while the third exhibited dehiscence of the facial canal which may have contributed to the condition. CONCLUSION Available evidence suggests that eustachian tube dysfunction can contribute to increased pressure within the middle ear, leading to neuropraxia of the facial nerve. Cases of facial paralysis associated with air travel are under-reported. Since there is no evidence-based management protocol for this condition, further investigation of its pathology is encouraged in order to improve our understanding.
