Chemical constituents, viable micro-organism and malignant cell content in ultrasonic scalpel plume: A literature review.

Purpose: To identify all published data on the chemical, micro-organism and malignant cell contents of ultrasonic scalpel plume, if any, and on any clinical implications of the contents on patients and operating staff.

Methods: Searches were conducted aiming to identify all published evidence on the chemical constituents, presence/absence of viable micro-organisms and malignant cells in ultrasonic scalpel plume. Attempts were made to source unpublished industry data.

Decompression of keratocystic odontogenic tumors leading to increased fibrosis, but without any change in epithelial proliferation.

Objective: The aim of this study was to investigate whether decompression treatment induces changes in the histology or biologic behavior of keratocystic odontogenic tumor (KCOT).

Study Design: Seventeen patients with KCOT underwent decompression treatment with or without enucleation. Histologic evaluation and immunohistochemical expression of p53, Ki-67, and Bcl-2 were analyzed by using conventional microscopy.

Caliber-Persistent Labial Artery: A Rarely Recognized Cause of a Lower Lip Swelling-Report of 5 Cases and Review of the Literature.
