This article presents six cases of oral psoriasis originally diagnosed by means of the histological changes found on biopsies of the oral lesions. Three of the patients presented with oral and skin psoriasis. Of the remaining three, two presented with oral manifestations alone, although their follow-up was short, whilst the third showed delayed dermatological changes. Two of the cases were also complicated by psoriatic arthritis, one of them to the temporomandibular joint.
Five new patients and six previously described patients with severe limitation in maximum mouth opening following transtemporal neurosurgical procedures are described. Six patients underwent an operation for epidural hematoma and three for skull-base meningloma; two were treated with a pterional craniotomy for an aneurysm. Limited maximum mouth opening in these circumstances is caused by temporal muscle scarring and shortening. Aggressive physiotherapy is potentially beneficial if started early. If, however, diagnosis is delayed, the efficacy of physiotherapy declines, and surgical treatments such as temporal muscle detachment and coronoidectomy are fully indicated. The differential diagnosis, prevention, and treatment of limited maximum mouth opening following neurosurgical procedures are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
