Conditions
Brief summary
The risk of Schneiderian membrane perforation and the postoperative complications of the sinus floor elevation surgery were evaluated for patients with and without history of COVID-19 infection.
Detailed description
COVID-19 induced chronic sinusitis with subsequent increased Schneiderian membrane thickness could increase the risk of its perforation during the sinus floor elevation. The aim of the study is to compare the incidence of Schneiderian membrane perforation and the postoperive complications of the sinus floor elevation in patients with and without history of COVID-19.
