Bread and Butter Sinus Imaging: Telling Your Referrers What They Need to Know (2026)-RC1061922-2026

Video Transcription

Video Summary

The transcript gives a detailed overview of sinonasal anatomy, imaging, disease patterns, surgery, and tumors. It starts with the nasal cavity, turbinates, meatuses, and paranasal sinuses, explaining how each sinus drains and why these drainage pathways matter. It highlights common anatomic variants such as concha bullosa, paradoxical turbinate curvature, agger nasi cells, Onodi cells, and frontal recess variants, all of which can affect obstruction or surgery.<br /><br />A major focus is on chronic rhinosinusitis and endoscopic sinus surgery. The speakers stress that most routine sinusitis does not need imaging, but CT and MRI become important when there are red flags such as facial or forehead swelling, orbital pain, proptosis, diplopia, altered mental status, or bone destruction. They describe serious complications including orbital cellulitis, cavernous sinus involvement, meningitis, empyema, ventriculitis, abscess, and venous sinus thrombosis.<br /><br />The transcript also emphasizes invasive fungal sinus disease, especially in diabetics or immunocompromised patients. Key imaging clues include black turbinate/necrotic mucosa, nonenhancing devitalized tissue, ulceration of the nasal cavity, and spread into the orbit, pterygopalatine fossa, or intracranial compartment.<br /><br />For chronic sinusitis and preoperative CT, the speakers outline patterns of disease, chronicity, polyposis, allergic fungal sinusitis, and mucoceles, along with surgical pitfalls such as incomplete uncinectomy, residual ethmoid cells, lateralized turbinates, scar/adhesion formation, and osteoneogenesis. Balloon sinuplasty and FESS are reviewed, including postoperative complications and reasons for revision surgery.<br /><br />Finally, sinonasal tumors are discussed, stressing that bone destruction, orbital invasion, intracranial extension, dural spread, and nodal disease are key imaging findings. MRI is recommended when CT cannot distinguish secretions from tumor.
