  The Art of Timing: Imaging in Sinusitis 17.07.2026 43мин

  Most clinicians rely heavily on CT scans for diagnosing and managing sinusitis — but when is the right time to order one, and when can it be safely skipped? In this episode of Rhinology Roundtable, Dr. Ashleigh Halderman hosts top experts Dr. Kevin Welch and Dr. Amber Luong challenge conventional wisdom around imaging, revealing how nuanced decision-making has become. Discover how to optimize CT timing to improve patient outcomes, avoid unnecessary radiation, and better understand the dynamic nature of sinus disease. They break down:The evolving role of pre- and post-treatment scans in CRS managementWhen to rely on symptoms, endoscopy, and imaging—individually or combinedThe impact of insurance policies and historical practices on imaging decisionsHow to interpret CT scans during active symptoms versus remission periodsStrategies for odontogenic sinusitis and complex cases where imaging changes everything (like in the case of sinus headache)If you're a trainee wondering what you will do when you start practicing after graduation, a clinician looking to optimize when you order imaging, or a specialist wanting to refine your approach, this episode provides practical insights rooted in decades of experience. You'll learn why some scans may be unnecessary, how to time them effectively, and how to integrate clinical cues with imaging findings. Understanding the proper timing and interpretation of CT scans can prevent missed diagnoses, reduce patient exposure to radiation, and streamline treatment pathways. Don't miss this deep dive into one of rhinology’s most debated topics—perfect for ENT residents, practicing rhinologists, and anyone eager to make evidence-based imaging decisions.

  Skull Base Osteomyelitis 22.05.2026 1ч

  Skull base osteomyelitis can humble even the most experienced clinicians. Unlike so many other disease processes, once the diagnosis is made, that’s when the real uncertainty begins. The lack of robust literature or clinical guidelines leaves treating physicians with few places to turn for answers.This episode sheds light on the complexities of diagnosing and managing skull-base osteomyelitis. Led by Dr. Ashleigh Halderman and featuring expert colleagues Dr. Erin McKean and Dr. Jacob Hunter, it emphasizes the importance of vigilance, multidisciplinary collaboration, and nuanced decision-making in treatment.Diagnostic challenges include subtle imaging changes, delayed symptoms, and often inconclusive biopsies; high suspicion is crucial.Empiric antibiotic therapy often lasts for months; duration and cessation are guided by clinical symptoms, not just imaging, with close monitoring.The typical 6 weeks of IV antibiotics treatment course for osteomyelitis frequently falls woefully short when the skull base is involved Imaging follow-up with MRI is clinically preferred for its superior anatomic detail, although resolution of abnormal findings lags clinical improvement.Surgical intervention is generally limited to diagnosis; outright eradication surgically is rare.Emerging imaging techniques like PET scans offer promising sensitivity and specificity but are not yet standard.Uncertainty remains around optimal treatment duration and criteria for stopping therapy, underscoring the importance of clinical judgment.00:00 - Introduction 02:18 - Spectrum of disease presentation and comorbidities03:14 - Navigating the limited evidence and guideline gaps07:33 - Differentiating lateral vs central skull-base disease09:25 - Symptoms suggestive of lateral and central involvement15:01 - Diagnostic delays and clues in history and exam17:43 - Importance of experience and pattern recognition21:17 - Imaging strategies: CT, MRI, nuclear scans, and PET26:10 - Role of endoscopy and nasopharyngeal assessment28:49 - Cultures, biopsies, and microbiological techniques31:33 - Approaches for deep infections34:53 - Drainage procedures and managing pockets of pus36:16 - Pathogens involved and microbiological testing40:13 - Interpreting culture results and contaminants43:53 - Antibiotic management, duration, and follow-up46:40 - Laboratory markers and their limitations49:54 - Imaging for monitoring treatment response53:24 - When to consider surgery and source control58:58 - The role of glycemic control and immunosuppression63:54 - Rare interventions and experimental therapies67:11 - Use of hyperbaric oxygen and adjuncts70:15 - Expert advice for clinicians: key tips and considerationsResources FDG PET for OsteomyelitisPMID 40105501: Defining the Appropriate Length of Antimicrobial Therapy for Skull Base OsteomyelitisPMID 36648119: Central Skull Base Osteomyelitis: A Case Series from a Tertiary Care Center Over 5 YearsDr. Erin McKean - | University of MichiganDr. Jacob Hunter - Thomas Jefferson University
