In the subsequent intratympanic dexamethasone group, 15 patients showed hearing recovery within 7\u00a0days and did not need intratympanic dexamethasone treatment. After intratympanic dexamethasone treatment, &gt;28% (25\/88) of the patients complained of otalgia, transient dizziness, ear fullness, and headache.

A considerable number of patients did not need intratympanic dexamethasone for idiopathic sudden sensorineural hearing loss, and some patients experienced unnecessary side effects due to intratympanic dexamethasone. Therefore, the use of intratympanic dexamethasone is recommended only for subsequent or salvage treatment of idiopathic sudden sensorineural hearing loss after systemic steroid treatment.<\/jats:p><\/jats:sec>","DOI":"10.1177\/0194599811418169","type":"journal-article","created":{"date-parts":[[2011,8,5]],"date-time":"2011-08-05T00:50:21Z","timestamp":1312505421000},"page":"1016-1021","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":33,"title":["Simultaneous
