“…Mean follow-up for the studies that documented this data was 48.76 months (range 1−192 months). Nine studies reported transient FND (Frawley et al, 2013; Goldstein et al, 2015; Lam et al, 2014; Lin et al, 2007; Mahrous Mohamed et al, 2011; Murage et al, 2014; Zellner et al, 2017) and 6 studies reported permanent FND (Konaş et al, 2016; Scott et al, 2011; Senders et al, 2010; Steinberg et al, 2016; Tahiri et al, 2015; Tibesar et al, 2010) while 1 study had both types of FND (Mudd et al, 2012); 1 study explicitly reported no FND in their cohort of patients (Martín-Masot et al, 2018); and 2 studies documented FND without noting the duration of palsy (Allam et al, 2011; Mao et al, 2019). Ten of 19 publications (47.4%) documented marginal mandibular branch (MMB) dysfunction (Allam et al, 2011; Frawley et al, 2013; Konaş et al, 2016; Lin et al, 2007; Mahrous Mohamed et al, 2011; Scott et al, 2011; Senders et al, 2010; Steinberg et al, 2016; Tibesar et al, 2010; Zellner et al, 2017), and 9 studies did not document which branch of the facial nerve was injured.…”
