[THE RATIONALE OF MINIMALLY INVASIVE SINUS TECHNIQUE (MIST)]

Chronic rhinosinusitis is one of the most common diseases in the world. Mucosal contact in narrow draining pathways of the sinuses (called transition spaces) may lead to chronic sinusitis by disruption of mucociliary clearance, stasis and blockage of mucous flow. Minimal invasive sinus technique (MIST) is a targeted procedure designed to address the transition spaces surrounding the natural sinus ostia. Surgical clearing disease in a transition space, allows the dependent sinus to recover function. Compared to other conventional endoscopic procedures, MIST can accomplish good and reproducible results in treating patients for chronic rhinosinusitis over long term follow-up.
