The literature reports an increasing occurrence of carcinoma in the young adult nonsmoking and nondrinking population. With it, this trend brings the potential for new comorbidities. This report discusses one such case in which a 30-year-old woman, 28 weeks pregnant, was diagnosed with a hybrid verrucous carcinoma/squamous cell carcinoma. Several years(More)
BACKGROUND Dentists frequently evaluate patients for oropharyngeal pain that may or may not eventually be related to oral pathology. Two rare neurological disorders that present with severe orofacial pain are trigeminal neuralgia, or TN, and glossopharyngeal neuralgia, or GPN. Both are secondary to cranial nerve compression by arteries and veins at the(More)
Craniomaxillofacial surgery has many indications for bone regeneration and augmentation, ranging from socket preservation to reconstruction of large skeletal defects. The discovery of bone morphogenetic proteins (BMPs) as osteoinductive agents and the subsequent development of commercially available recombinant forms of BMPs have offered the potential to(More)
Intraoral surgical procedures produce scar tissue formation that may limit mandibular opening. Many procedures have been developed to release these scar contractures, but most lead to further scar formation and greater limitation in opening. The purpose of this article to describe a technique with the use of an intraoperatively fabricated self-curing(More)
PURPOSE A device consisting of powdered porcine urinary bladder extracellular matrix (UBM-ECM) encapsulated within sheets of the same material was investigated as a scaffold for temporomandibular joint (TMJ) meniscus reconstruction. MATERIALS AND METHODS Five dogs underwent unilateral resection of the native meniscus and replacement with a UBM-ECM device.(More)
PURPOSE A device composed of extracellular matrix (ECM) was investigated as an inductive template in vivo for reconstruction of the temporomandibular joint (TMJ) disk after discectomy. MATERIALS AND METHODS A scaffold material composed of porcine-derived ECM was configured to mimic the shape and size of the TMJ. This device was implanted in a canine model(More)
Obstruction of the lacrimal drainage apparatus may result in excessive tearing or epiphora. This may occur as a result of a traumatic injury or accumulation of debris, mucus, or pus. In nuclear dacryoscintigraphy, a radioactive solution is introduced into the conjunctival sac by pipette and allowed to follow the flow of the tear solution through the(More)
