Original description
Exparel has a proven efficacy in providing pain relief for up to 72 hours with a single-dose administration at surgical sites. The study aims to evaluate the effectiveness of endoscopically-guided injection of Exparel (Bupivacaine) for the treatment of craniofacial pain. This study would be conducted in a prospective, randomized, double-blinded, placebo- controlled, and cross-over fashion. We aim to investigate whether the administration of Exparel (Bupivacaine) to the lateral nasal wall may positively impact craniofacial pain and functional outcomes, in patients who experience relief with the topical application of Lidocaine (routinely given prior to almost all ENT endoscopy).Read full original descriptionShow less

Prospective, Randomized, Double-blinded, Placebo-controlled, Cross-over Trial of Endoscopically Guided Injection of Exparel (Bupivacaine) Towards the Ipsilateral Pterygopalatine Fossa for the Treatment of Craniofacial Pain

Exparel has a proven efficacy in providing pain relief for up to 72 hours with a single-dose administration at surgical sites. The study aims to evaluate the effectiveness of endoscopically-guided injection of Exparel (Bupivacaine) for the treatment of craniofacial pain. This study would be conducted in a prospective, randomized, double-blinded, placebo- controlled, and cross-over fashion.

Inclusion: Patients with a chief complaint of craniofacial pain (migraine, cluster headache, trigeminal autonomic cephalgia, sphenopalatine ganglioneuraligia, paroxysmal hemicrania) who has Stanford Pain \& ENT clinic visit.
