Chronic Sinusitis – For those patients who are unable to benefit from anti-allergic measures and medications, surgery becomes an important consideration in management. The simplest form of surgery is a sinus washout done under local anaesthesia. The cheek sinuses are irrigated to wash out pus within the sinuses, and to open the sinus ostia by forcing the irrigation fluid through it.
Some common Rhinosinusitis cases seen on CT scans
Improving sinus drainage with surgery
Sinus surgery aims to restore sinus health by:
- Opening up blocked and narrowed sinus openings
- Removing diseased & abnormal tissue from within the sinuses (eg nasal polyps)
Functional Endoscopic Sinus Surgery (FESS) hastens recovery
FESS is a minimally invasive surgery done through the nose without any external cuts on the nose or face. It may be used for the treatment of:
- Sinus Infections
- Chronic sinusitis Headaches and Congestion
- Fungal sinusitis
- Nasal polyps
- Complications of sinusitis
FESS surgery is performed though a computer imaging guidance system (IGS) with video attachment to the endoscope that allows the surgeon to look at a video monitor while operating. It is less of a physical strain on the surgeon. The FESS surgeon can spend a longer time on the operation with increased safety and better outcomes for the patient.
Computer Aided Navigation Sinus Surgery improves surgical precision
- Allows surgeon to use high resolution CT scan imaging data to navigate precisely and safely in the patient’s sinuses during surgery
- CT scans use X-rays to product images
- Allows the surgeon to see into the patient’s sinus anatomy with X-ray vision!
- Helps surgeon confirm his position in the patient’s sinuses
- Every point in the patient’s sinuses has an x, y & z coordinate (real coordinates)
- Image guided surgery works by matching and co-relating the real coordinates with the virtual coordinates
- Produces 3D localisation information for navigation during surgery
- Allows surgeon to identify & avoid danger areas in the patient’s anatomy
- Enhances the safety of sinus surgery
(For a better understanding of who image guidance system is used in a sinus surgery, please watch video explanation listed at the end of this page.. video 7)
Surgeons, like pilots, need good navigation. Occasionally, in complex sinus operations, surgeon need to identify the eye optic nerve, carotid blood vessels, nasolacrimal duct, and base of skull. In these instances, computerized navigation instruments are available to lend a guiding hand. Computer navigation is particularly useful if the anatomical structures in the sinuses are distorted by developmental factors or previous surgery. It gives the surgeon good navigation to chart the course within the complex labyrinth of the nose and sinuses.
Endoscopic Rod Improves visualisation
The Hopkin’s endoscopic rod which is made of glass rod lenses with fibreoptic bundle allows more accurate diagnosis of the causes of sinusitis and enhance surgeon’s ability to perform sinus surgery by peering through the nostrils instead of having to make unsightly facial incisions.
Vacuum suction Microdebrider improves surgery safety
Microdebrider is an oscillating vacuum shaver (or microdebrider) often used during sinus surgery. This surgical instrument works like a hybrid between a vacuum cleaner and a hair trimmer. The trimmer chops off unwanted abnormal tissues, while the vacuum suction clears away unwanted debris and blood from the area of operation.
Advantages of the Microdebrider
- Allows the surgeon to remove diseased tissue in a precise manner.
- Cuts tissues sharply, without causing tearing and shearing that would have resulted with conventional sinus surgery instruments.
- Reduces unnecessary damage to the sinus tissues, resulting in less scarring and more rapid healing.
- Allows timely and opportune removal of blood and tissue keeping the operation site clean so the surgeon can proceed safely and smoothly under conditions of good visibility.
