In animals, the most commonly used surgical methods for viral gene therapy delivery to the cochlea are the round window and the cochleostomy approaches. However, the patterns of viral infection and the effects on hearing have not been directly compared between these two approaches. In this study, we compare the patterns of cochlear infection and effects on hearing between these two surgical approaches using adeno\u2010associated virus serotype 2\/8 (AAV8) as the gene delivery vehicle.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Study Design<\/jats:title>\n                    <jats:p>Animal study and basic science research.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>One\u2010 to two\u2010month\u2010old CBA\/J mice were used in this study. AAV8\u2010green fluorescent protein (GFP) was delivered to the cochlea by either the round window or the cochleostomy approach (described below). Auditory brainstem response was used to examine hearing thresholds before and after surgery. Animals were examined at 1, 2, 3, and 4 weeks after surgery for the patterns of cochlear infection and hearing loss.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Cochlear gene transfer was successful through both surgical approaches. In both approaches, AAV8\u2010GFP mostly infected the inner hair cells. There was occasional low\u2010level infection of the outer hair cells and supporting cells. The two surgical approaches resulted in comparable viral infection efficiencies. The round window approach resulted in less surgical trauma, as indicated by hearing loss, than the cochleostomy approach.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Adeno\u2010associated virus\u2010mediated gene transfer to the cochlea can be accomplished using either the round window or the cochleostomy surgical approach.
