A clinical comparison chart displaying three treatment modalities in vertical columns with icons, percentage metrics, and outcome indicators. Each column uses distinct color coding and includes graphical representations of success rates, complication profiles, and patient ambulation data. Statistical data is presented with bar graphs and numerical percentages.

The text on each slide
  1. Made possible by Cincinnati Children's | PEDIATRIC NECK MASS | A CHILD HAS PAINLESS NECK SWELLING AFTER A VIRAL ILLNESS. WHAT'S ON YOUR DIFFERENTIAL? | A real case. Make your call, then swipe.
  2. Made possible by Cincinnati Children's | THE DIAGNOSIS | BRANCHIAL CLEFT CYST | A congenital neck mass — tissue that failed to develop properly in embryonic growth. CT shows a cystic mass running from the thyroid up to the piriform sinus. It often improves with oral antibiotics. | Swipe right
  3. Made possible by Cincinnati Children's | THE SWELLING TEMPTS YOU TO DRAIN IT. | When it flares, incision & drainage feels like the move. But on a branchial cleft cyst, an early I&D can make the definitive excision harder down the road. | Swipe right
  4. Made possible by Cincinnati Children's | THE BEDSIDE RULE | WAIT UNTIL YOU'RE READY TO TREAT THE TRACT. | We try to avoid any interventions until we're ready to resolve it — I&Ds make these more challenging to remove later. | Douglas von Allmen, MD | Member, Division of Otolaryngology - Head and Neck Surgery | Associate Professor, UC Department of Otolaryngology, Head and Neck Surgery | Swipe right
  5. Made possible by Cincinnati Children's | FINAL POINT | REMEMBER THIS | For branchial cleft cysts, endoscopic cauterization matches open excision on recurrence — while sparing open-surgery morbidity and the risk of recurrent laryngeal nerve injury.
