Limitations
There were various limitations to the current study. First, the sample was selected from a tertiary care setting and had a long median duration of facial palsy. The character of complaints experienced by patients has been reported to evolve over time.7 This might mean that the relative importance of each FaCE subscale in acute facial palsy may be different from our findings. Second, the tertiary care setting meant that acoustic neuroma was the most common etiology, instead of Bell’s palsy as is seen in the general facial palsy population. Third, patients at our clinic are generally suffering from severe facial palsy requiring surgery. Mild cases only involving regional paralysis or synkinesis are infrequently seen. Lastly, the sample size to evaluate validity and reliability of the VAS was relatively small.
