We appreciate the opportunity to comment the observations on our paper entitled "Score risk scale as a prognostic factor after sudden sensorineural hearing loss", by Capuano et al. This letter highlights several important points, including the role of hyperbaric oxygen therapy and the possible association between patent foramen ovale and sudden sensorineural hearing loss (SSHL). Further research is needed to strengthen the association between cardiovascular risk and SSHL. We thank the authors for their insights into our paper and for adding their experience and observations on the potential role of cardiovascular risk in the etiology of SSHL.
