RESUMO
Injectable cosmetic fillers are increasingly popular, but are not often considered as a cause of abnormal findings on imaging. We present a case of poly-L-lactic acid (PLLA) filler associated with 18-fluorodeoxyglucose (FDG) uptake, which had the potential to interfere with staging of a squamous cell carcinoma of the lateral tongue. We characterise the FDG-positron emission tomography/computed tomography (PET/CT) properties of a PLLA dermal filler, Sculptra® (Aventis), and highlight its potentially confounding appearance in the staging scans of oncological patients, particularly those with oral tumours.

Exposure to excessive noise could impair surgical performance and communication, and lead to long-term hearing loss, but it is only recently that studies on occupational exposure to noise in operating theatres have been published. The aim of this prospective study was to assess mean and peak levels of noise during maxillofacial operations. We found that both were comparable to those in other surgical specialties such as orthopaedics in which power tools are used.
