A new surgical technique for treating perforations of the tympanic membrane (eardrum) in children and adults has been developed at the Sainte-Justine University Hospital Center, an affiliate of the Université de Montreal, by Dr. Issam Saliba. The new technique, which is as effective as traditional surgery and far less expensive, can be performed in 20 minutes at an outpatient clinic during a routine visit to an ENT specialist. The result is a therapeutic treatment that will be much easier for patients and parents, making surgery more readily available and substantially reducing clogged waiting lists.
Myringoplasty is surgical procedures to repair the tympanic membrane or eardrum when it has been perforated or punctured as the result of infection, trauma or dislodgement of a myringotomy tube (also known as a pressure equalization tube). Surgical repair of the perforation will allow the patient to recover his or her hearing and prevent repeated ear infections, particularly after swimming or shower. Traditionally, these procedures are performed using what are known as lateral and medial techniques, which require hospitalization for at least one day, and 10 to 15 days off work.
"In the past five years, I've operated on 132 young patients in the outpatient clinic at the Sainte-Justine UHC using this technique, as well as on 286 adults at the University of Montreal Hospital Centre (CHUM) outpatient clinic," says Dr. Saliba. "Regardless of the size of the perforation, the results are as good as those obtained using traditional techniques, with the incomparable advantage that patients don't have to lose an entire working day, or 10 days or more off school in the case of children."
The technique, which Dr. Saliba has designated HAFGM (Hyaluronic Acid Fat Graft Myringoplasty), requires only a scalpel, forceps, a probe, a small container of hyaluronic acid, a small amount of fat taken from behind the ear, and a local anesthetic. The operation, which is performed through the ear canal, allows the body to rebuild the entire tympanic membrane after about two months on average, allowing patients to recover their hearing completely and preventing recurring cases of ear infection. Because it requires no general anesthetic, operating room or hospitalization, the technique makes surgery much more readily available, particularly outside large hospital centers, and at considerably lower cost.
"Myringoplasty (reconstruction of the eardrum) using the HAFGM technique reduces waiting times, cost of the procedure and time lost by parents and children. What's more, it will help clear the backlogs on waiting lists," Dr. Saliba says.
