AGENDA – LECTURE DAY (October 15)
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.
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.
- Review endoscopic and radiologic sino-nasal anatomy, as well as pathophysiologic concepts of various common nasal diseases;
- Become familiar with the management of sino-nasal pathology, including the latest medical therapies as well as advanced ESS techniques, including the surgical steps of each technique;
- Be able to discuss the indications and contraindications of advanced ESS techniques;
- Understand and perform the surgical management of complications of ESS including CSF leak and ICA injury
- Become familiar with the instrumentation required;
- Be able to discuss the postoperative management after ESS.

Details and Learning Objectives
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 Master’s Class 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 the building block method 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.
Learning Objectives for the Frontal Sinus Masterclass
- Review the nomenclature and common cellular configurations of frontoethmoidal cells that are relevant to frontal sinus surgery.
- Practice reconstructing these 3D configurations using the building blocks technique and understanding how this affects the frontal sinus drainage pathway.
- Develop a surgical plan for frontal recess dissection based on the elucidated frontoethmoidal cell anatomy.
