What Is the Incidence of Anesthesia-Related Adverse Events in Oral and Maxillofacial Surgery Offices? A Review of 61,237 Sedation Cases From a Large Private Practice Consortium.

Background: The safety of the anesthesia team model performed in oral and maxillofacial surgery (OMS) offices has been criticized by professional and mainstream media.

Purpose: This study aims to assess the incidence of adverse anesthetic events (AEs) associated with the OMS anesthesia team model and identify risk factors associated with AEs.

Study Design, Setting, Sample: This was a retrospective cohort study utilizing a patient database from Paradigm Oral Health, Lincoln, Nebraska, a managed service organization (MSO).

Angiogenesis and CD34 expression as a predictor of recurrence in oral squamous cell carcinoma.

Purpose: To assess immunohistologic features of angiogenesis of T1N0M0 oral squamous cell carcinoma (OSCC), and to identify predictors of regional recurrence. The identification of prognostic markers of early lymph node involvement in OSCC could allow for the use of more targeted biologic therapies for patients with early-stage tumors.

Patients And Methods: The study included patients treated for T1N0M0 OSCC at the Mayo Clinic from 1986 to 2001.
