Purpose of review: To understand the theory and application of the surgical model for endoscopic sinus surgery termed minimally invasive sinus technique (MIST). In simple terms: What is MIST? When should we use it? Does it work?
Recent findings: Several recent publications have addressed the efficacy of MIST. Using reliable outcome instruments and a 23-month follow-up period, results following MIST were found to equal or surpass those following functional endoscopic sinus surgery (FESS). These results were valid across the spectrum of disease severity. Other reports address the reduced revision rate (compared with FESS) following initial intervention with MIST, the potential to markedly reduce the rate of intranasal synechiae, and the reduction in immediate postoperative morbidity.
Summary: The authors believe that MIST should be considered as the initial surgical intervention offered to patients undergoing surgery for the treatment of chronic rhinosinusitis.
