A niche narrowed to less than 0.8 mm in diameter was rare and tended to affect both ears (5.6% first ears and 5.95% second ears; \u03c7\n                      <jats:sup>2<\/jats:sup>\n                      = 134.6 on 4 df; p &lt; .0001). The degree of footplate otosclerosis was classified and amalgamated into 3 broad categories: Minor (47.2%), moderate (21.6%), and severe (31.2%).
