Traditionally, SSNHL is treated with steroids, either orally (OCS) and\/or via intratympanic injection (ITSI). Hyperbaric oxygen treatment (HBOT) has resurged in popularity as an adjunctive therapy. The present study investigated the additive effect of HBOT to traditional steroid treatment for SSNHL.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Retrospective study comparing treatment effect (pure tone average\u2013PTA; speech recognition threshold\u2013SRT; word recognition score\u2013WRS) between HBOT\u2009+\u2009ITSI and ITSI treated patients.
