BACKGROUNDPosterior cheek enlargement in human immunodeficiency virus (HIV)+ individuals can lead to significant cosmetic disfigurement. Both parotid gland and masseter muscle overlie the mandibular ramus, contributing to lower facial contour. However, posterior cheek enlargement has not been well characterized anatomically. There are also limited treatment options. Botulinum toxin is a highly efficacious minimally invasive option for improving the shape of the lower face.OBJECTIVEA pilot study was undertaken to better characterize posterior cheek enlargement in HIV+ patients and explore treatment with botulinum toxin A.MATERIALS AND METHODSFive HIV+ patients with posterior cheek enlargement were treated with botulinum toxin A. Clinical, photographic, and radiological evaluations allowed the precise calculation of any change in volumes resulting from botulinum toxin A.RESULTSAll 5 patients had a good response with a mean decrease of 21.4% and 11.2% in the volumes of the masseter muscle and parotid gland, respectively. The effect was long lasting even at 6 months after injection and well tolerated.CONCLUSIONBotulinum toxin A may be a less invasive treatment of posterior cheek enlargement in HIV+ patients, with advantages of a good result that is long lasting with good tolerability and minimal risk.
