II. Pathophysiology
- Benign bony growth of ear canal
- Composed of dense compact bone
III. Epidemiology
- Associated with cold water swimming
- Most common tumor of auditory canal
IV. Symptoms
- Conductive Hearing Loss (typically painless)
V. Signs
- Bilateral, multiple bony growths within the external auditory canal
- Adjacent to Tympanic Membrane
VI. Differential Diagnosis
VII. Management
- Excision if Hearing Loss or Otalgia
- Excision Indications
- Obstructive symptoms (e.g. Conductive Hearing Loss)
- Secondary infection
