Recalcitrant chronic rhinosinusitis (CRS) and aggressive clinical variants of the disease such as nasal polyposis, Samter’s triad and eosinophilic mucus CRS are particularly challenging to manage, even in the hands of experienced otolaryngologists. In this era of novel biologic medications, numerous consensus statements have emphasized the importance of adequately complete endoscopic sinus surgery early in the management algorithm of nasal polyposis. Advances in endoscopic sinus surgery technique and ancillary procedures, and our understanding of the disease process have led to improved success rates for surgery in the management of severe disease.

Now in its fifth iteration and 10 years after the inaugural course, the North American Masterclass in Endoscopic Sinus Surgery is returning to Montreal with Professor Peter-John Wormald as guest of honour. The aim of this course is to teach advanced techniques in endoscopic sinus surgery, including frontal recess dissection and drillout, medial maxillectomy, with the aim of increasing the surgical skills of participating surgeons.

The course will consist of a half-day of high-yield lectures followed by two and a half days of hands-on dissections. As in 2019, which was the first international sinus course to do so, this course will employ the latest cutting edge high-fidelity 3D-printed sinus models provided by Fusetec (). Ultra-realistic in anatomic detail and tissue feel, these models offer significant advantages over cadaveric specimens including standardized and graded frontal sinus complexity, and CT imaging for surgical planning. Twenty surgical stations endoscopic surgical workstations will be available with 3 models station, and the enrollment would be open to a total of 40 Otolaryngologists, including practicing surgeons, advanced trainees and fellows from around the globe.

LEARNING OBJECTIVES

After attending this workshop, otolaryngologists will be able to:

1. Recognize endoscopic and radiologic sino-nasal anatomy, as well as pathophysiologic concepts of various common nasal diseases;
2. DefineÌýthe management of sino-nasal pathology, including the latest medical therapies as well as advanced ESS techniques, including the surgical steps of each technique;
3. IdentifyÌýthe indications and contraindications of advanced ESS techniques;
4. ListÌýthe instrumentation required;
5. DefineÌýthe postoperative management after ESS.

Frontal Sinus Masterclass Workshop (included for dissectors)

The frontal sinus anatomy is highly variable and often complex. As a result, it is often challenging for the sinus surgeon to master understanding of the frontal sinus. The Frontal Sinus Masterclass aims to help participants systematically review a variety of CT scans, from simple to complex, in all 3 planes. After reviewing the CT, the participant uses specially designed building block software to determine the anatomy and drainage pathway of the frontal sinus.

The Course Faculty works with the participants to make and evaluate their own 3D conceptualization of the frontal sinus cells using tangible blocks, in a hands-on approach. The Course Faculty checks and provides feedback to help the participant improve their 3D Conceptualization.

Participants then compare their own 3D interpretation of the CT scan with the intra-operative video of the surgery performed on this patient, with stepwise removal of frontal sinus cells. The comparison of the participant’s 3D Interpretation and the actual surgery re-enforces their ability to use the triplanar CT images to create a 3D anatomical picture, and to formulate their own plan for surgery. Participants will subsequently use this surgical planning technique to dissect their individual sinus models during the dissection protion of the course.

LEARNING OBJECTIVES

After attending this workshop, otolaryngologists will be able to:

1. Name common cellular configurations of frontoethmoidal cells that are relevant to frontal sinus surgery.
2. Assemble these 3D configurations using the building blocks technique and understanding how this affects the frontal sinus drainage pathway.
3. Create a surgical plan for frontal recess dissection based on the elucidated frontoethmoidal cell anatomy.

ACCREDITATION
