Standardized photography techniques for facial palsy may be necessary
Findings from a recent study indicated that no consensus exists on reporting outcomes in patients with facial palsy or paralysis.
The researchers conducted a literature review of 393 articles in an attempt to codify photographic standards in patients with facial palsy and document facial nerve function. There were seven studies included in the final analysis, six of which addressed views specific to this patient population. They contacted 151 members of the Sir Charles Bell Society, of whom 83 responded to the survey.
Although all respondents used photographic documentation, variability was reported in the facial expressions used by patients. Some form of videography was used by 82% of respondents.
From the data at hand, the researchers proposed a minimum set of standards for photographs of these patients that included 10 static views. Those views include: “at rest or repose, small closed-mouth smile, large smile showing teeth, elevation of eyebrows, closure of eyes gently, closure of eyes tightly, puckering of lips, showing bottom teeth, snarling or wrinkling of the nose and nasal base view,” they wrote. – by Rob Volansky
