- The ENT reports that there is a retraction pocket. What is a retraction pocket, and what pathology may be a sequela of untreated retraction pocket?
- Does this pathology explain the middle ear resonant frequency? How/how is it not consistent? What are the standards for when to refer to ENT for negative pressure? Would you do so differently depending upon the patient’s age?
- Google and/or “medline” “hysteresis, retraction pocket” – does a presence of a retraction pocket create a negative pressure peak in the absence of true middle ear negative pressure?
