Abstract
ObjectivePeripheral facial palsy (PFP) is predominantly a unilateral disorder of the facial nerve, which can lead to psychological disorders that can result in decreased quality of life. The aim of this systematic review was to assess anxiety, depression and quality of life symptoms associated with PFP.Data sourcesWe searched the Medline, PEDro, CINAHL and Google Scholar databases to conduct this systematic review while following Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards. The search was performed by two independent reviewers, and differences between the two reviewers were resolved by consensus.Study SelectionThe search terms used were derived from the combination of the following MeSH terms: “facial paralysis”, “bell palsy”, “anxiety”, “anxiety disorders”, “depression”, “depressive disorders”, “quality of life” and not MeSH: “facial palsy”, “hemifacial paralysis”, “facial paresis”, “Peripheral Facial Paralysis”, using the combination of different Boolean operators (AND/OR).Data ExtractionOn November 1st (2019).Data SynthesisIn total, 18 cross-sectional articles and two case-control studies were selected.ConclusionsThe cross-sectional articles showed low methodological quality, while the case-control studies showed acceptable methodological quality. Limited evidence suggests that patients with PFP might have increased levels of anxiety and depressive symptoms. A qualitative analysis also showed limited evidence that quality of life might be diminished in patients with PFP.PROSPEROCRD42020159843.
Highlights
Peripheral facial palsy (PFP) is predominantly a unilateral disorder of the facial nerve (VII cranial nerve), a mixed nerve with both motor and sensory fibers, whose main function is to control the facial expression muscles
The search terms used were derived from the combination of the following MeSH terms: “facial paralysis”, “bell palsy”, “anxiety”, “anxiety disorders”, “depression”, “depressive disorders”, “quality of life”, and not MeSH: “facial palsy”, “hemifacial paralysis”, “facial paresis”, “Peripheral Facial Paralysis”, using the combination of different Boolean operators (AND/OR)
Results of the methodological quality assessment Of the 20 articles included in this systematic review, 18 were cross-sectional observational studies, and 2 were case-control studies
Summary
Peripheral facial palsy (PFP) is predominantly a unilateral disorder of the facial nerve (VII cranial nerve), a mixed nerve with both motor and sensory fibers, whose main function is to control the facial expression muscles. PFP is related to a loss of essential facial functions, such as blinking, nasal breathing, lip sealing, smiling or speaking (Roob, Fazekas & Hartung, 1999; Lorch & Teach, 2010). PFP is characterized by a diminished sense of taste (Roob, Fazekas & Hartung, 1999; Lorch & Teach, 2010)
