As noted (see above), palsy of CN III and, occasionally, of CN IV and CN VI may occur. Rarely, simultaneous involvement of other CNs has been reported. The most common such event is CN VII involvement, which may produce facial palsy.

Svozilkova et al reported 1 case of varicella-caused retinal necrosis after ocular trauma. [60]

Intraoral herpes zoster

HZO may involve the skin or the oral cavity, or both simultaneously. Trigeminal herpes zoster with Ramsay Hunt syndrome may produce cutaneous, intraoral, and otic vesicles; hearing loss; and mild facial palsy. [16] Herpes zoster of the maxillary division of the trigeminal nerve may begin with toothache during its prodromal stage, followed by its vesicular eruption. [61] Herpes zoster maxillaris may involve a unilateral maxillary canine to resemble pulpal necrosis and apical periodontitis. Thus, gingival herpes zoster may be evident as painful desquamative vesicles or a pulpal disorder. [62]
