Orthognathic surgery, TMJ, facial pain, facial and oral lesions, IV sedation, dentoalveolar, cleft lip/cleft palate repair, dental implants and facial trauma are some of the services we provide to JPS Health Network. The oral & maxillofacial surgery outpatient clinic is one of the busiest and most productive of all outpatient specialty clinics in the hospital.

Currently we have 5 Interns and 3 Upper-level residents from the UT Southwestern/Parkland Program. The interns are here all year and each upper level resident is here for three months of each year.
