Otosclerosis
- Abnormal bone growth of the bony labyrinth
- The stapes becomes increasingly fixated to the oval window -> progressive conductive HL

  - Females
  - Adults
- 50% autosomal dominant, 50% sporadically
- Diagnosis
  - Decreased air conduction on pure tone
  - Carhart notch on audiogram
  - Normal otoscopy
- Treatment
