Open Access and Article Processing Charge (APC)

All articles published in Sinusitis and Asthma (ISSN 2624-7003) are published in full open access. In order to provide free access to readers, and to cover the costs of peer review, copyediting, typesetting, long-term archiving, and journal management, MDPI uses article processing charges (APCs). At present, the APC for Sinusitis and Asthma is fully subsidized by MDPI, meaning there is no charge to authors or their institutions.

Invoices are emailed shortly after acceptance to the payment contact provided by the authors. Only official invoices issued by MDPI ( are valid. We do not authorize any third party to collect the APCs. MDPI is the sole service provider and cannot be held liable for actions by third parties.

Local VAT or Sales Tax will be added if applicable.

Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
