Clinical Analysis Of 171 Cases With Peripheral Facial Nerve Paralysis

Objective: To analyze the causes, therapies and curative effects of peripheral facial nerve paralysis.Methods: A retrospective study was carried out of 171 cases with peripheral facial nerve paralysis treated in the First Affiliated Hospital of Chongqing Medical University from January 2013 to September 2015. The curative effects were evaluated by House-Brackmann facial nerve grading scale.Results: Of 171 cases, 82 cases(47.95%) were Bell paralysis, 36 cases(5.84%,14.04%,1.17%) were paralysis after surgery of otitis media, parotid neoplasms and acoustic neuroma, 23 cases(13.45%) were Hunt syndrome,19 cases(11.11%) were caused by temporal bone trauma, 6 cases(3.5%)were caused by tumors, 5 cases(1.75%,0.58%,0.58%) were caused by otitis media, otitis externa and infection after mastoid surgery. The patients were treated by either surgery or medicines. The patients in operation group including 18 cases with trauma, 3 cases with tumors and 2 cases with otitis media, were treated by different surgical procedures. These patients had different recovery of facial function. The patients in conservationgroup including 82 cases with Bell paralysis, 36 cases with paralysis after surgery, 23 cases with Hunt syndrome, 3 cases with tumors, 1 cases with trauma, 3 cases with infection, were treated by medicines such as glucorticoid, anti-infection drugs, antiviral drugs, neurotrophic agents and adjuvant therapies. These patients had different recovery of facial function.Our results showed that the patients with shorter course and less facial nerve dysfunction had better recovery of facial paralysis.Conclusion: The higher recovery rate of facial function is closely related to ideally combined therapies of medicine and/or surgery following an appropriate diagnostic program composed of careful analysis on the etiology and related examinations. The prognosis of peripheral nerve paralysis may be related to the course and severity of palsy.
