Ottawa: 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 Centre, affiliated to the University of 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.
“In the past five years, I have 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 parents 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 basic materials: a scalpel, forceps, a probe, a small disc of hyaluronic acid, a small amount of fat taken from behind the ear and a local anaesthesia. The operation, which is performed under a microscopic vision through the ear canal, allows the body by itself to rebuild the entire perforated tympanic membrane after about two months on average, allowing patients to recover their hearing completely and preventing recurring cases of ear infection (otitis). Because it requires no general anaesthesia, operating room or hospitalization, the technique makes surgery easier to perform, much more readily available, particularly outside large hospital centres, and at considerably lower cost.
“With the traditional techniques, you have to be on the waiting list for up to a year and a half in order to be operated on. 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.
Myringoplasty is surgical procedure 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 overlay and underlay techniques, which require hospitalization for at least one day, and 10 to 15 days off work. Every year in Quebec, some 750 myringoplasties are performed on adult or child patients.
This new form of eardrum surgery is based on results of a four-year prospective cohort study of 208 children and adolescents, 73 of whom were treated using the new HAFGM technique. The study has been published in the Archives of Otolaryngology – Head and Neck Surgery by Dr Issam Saliba, otolaryngologist (ear, nose and throat or ENT specialist), surgeon and researcher at the Sainte-Justine University Hospital Centre affiliated with the University of Montreal, where he is also professor of otology and neuro-otology. Dr Saliba is also a surgeon and researcher at the CHUM, where he conducted a similar study, applying the same HAFGM technique to cohorts of adult patients between 2007 and 2010, which was published in the August 20, 2008 issue of the journal Clinical Otolaryngology and subsequently in the February 12, 2011 issue of The Laryngoscope.
