There is evidence that cholesteatoma has a heritable component. Treatment includes multiple and aggressive surgeries.

These changes are pharmaceutically reversible, and epigenetic research has led to the FDA approval of several agents used in cancer treatment.<\/jats:p>\n                    <jats:p>Our goal was to review the literature investigating epigenetics in cholesteatoma to understand its role in pathogenesis and identify targets for epigenetic agents.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Data Sources<\/jats:title>\n                    <jats:p>PRIMSA 2020 statement was used as the framework.

Only a few included pediatric subjects. Most investigated non\u2010coding RNAs as the epigenetic mechanism; although one study investigated histone modifications and two investigated RNA methylation. Overall, there was differential expression of several noncoding RNAs in cholesteatoma. These noncoding RNAs are involved in regulation of cytokines and molecules that affect proliferation and apoptosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Epigenetic changes may contribute to the pathogenesis of cholesteatoma through dysregulation of several biological pathways.
