Botulinum toxin used to treat patients with masseteric muscle hypertrophy
According to the Australian Medical Association (AMA) when conditions for staff and patients at regional hospitals are compared with those at city hospitals, our country cousins lose out. A Clinicians Hospital Improvement Coalition has banded together comprised of the AMA, the Hospital Reform Group and the Doctors Reform Society and according to AMA president Brian

For patients with an uncommon condition causing a swollen appearance of the lower face, treatment with botulinum toxin type A (Botox) provides an effective alternative to plastic surgery, according to a study in the November Journal of Craniofacial Surgery.
Dr. Gianpaolo Tartaro and colleagues of Seconda Universit?egli Studi di Napoli, Italy, report on the use of botulinum toxin type A to treat patients with masseteric muscle hypertrophy (MMH). Patients with MMH have painless enlargement of the masseter (cheek) muscles, causing a swollen or “square-faced” appearance. The cause of MMH is unknown. In the past, the only treatment option was plastic surgery to remove part of the masseter muscle and/or jawbone.
Dr. Tartaro and colleagues used botulinum toxin type A to treat MMH in five patients-three women and two men, aged 46 to 56 years. Known by the brand name Botox, botulinum toxin is commonly used for cosmetic plastic surgery, including treatment of forehead wrinkles. Injected into muscles, the toxin blocks nerve transmission, causing those muscles to relax.
In the MMH patients, botulinum toxin was injected directly into the swollen masseter muscle. An average of 20 days later, the patients had reduced swelling and improvement in the contour of the lower face. In one patient, treatment had to be repeated on one side of the face. None of the patients had any complications, and all were highly satisfied with their results.
Botulinum toxin has become a useful treatment for a wide range of problems affecting the facial muscles-not just for “cosmetic” issues like frown lines and wrinkles, but also for problems of eye alignment (strabismus), facial muscle spasms, and others.
The new study adds to previous reports showing that botulinum toxin injection is a safe and effective alternative to plastic surgery for patients with lower facial deformity caused by MMH. Dr. Tartaro and his coauthors conclude, “[T]his study suggests that the use of botulinum toxin type A?can be established as a simple, predictable, alternative facial contouring procedure.”
Who knows what evil lurks in the hearts of men? Dr. Prabir Bhattacharya and his computers might. He and Concordia graduate student Abu Sayeed Sohail are developing a computer image processing system that detects and classifies human facial expressions. The aim of this system is to take and analyze photos of individuals, potentially in areas

The novel design of a deep muscle along the spinal column called the multifidus muscle may in fact be key to spinal support and a healthy back, according to researchers at the University of California, San Diego School of Medicine. Their findings about the potentially important “scaffolding” role of this poorly understood muscle has been

Surgeons in the United States have carried out America’s first face transplant at a clinic in Cleveland, Ohio where a woman has had 80% of her face replaced with that of a deceased female donor. The operation which was conducted by reconstructive surgeon Dr. Maria Siemionow along with a team of seven other doctors, is

However, their facial injuries speak volumes. Newly released research in the January/February issue of Archives of Facial Plastic Surgery, one of the JAMA/Archives journals, shows women who are victims of intimate partner violence tend to have different patterns of facial injury than women who experience facial trauma from other causes.

Joyful or sad smiles expressed after a competition are the same for blind and sighted athletes, says a new study, showing that certain facial expressions are innate and managed differently depending on the social situation. “Spontaneously produced facial expressions of emotion of both congenitally and non-congenitally blind individuals are the same as for sighted individuals
