Abstract

Introduction: The Schneiderian membrane is the mucous membrane that covers the inner aspect of the maxillary sinus cavity. It is very important to pre-operatively evaluate its thickness for planning the surgical procedure in the region that involves the membrane, such as a sinus lift augmentation, which increases the possibility of membrane perforation or other complications.Aim: To assess the thickness of the Schneiderian membrane of the maxillary sinus and its correlation with demographic parameters. Materials and methods: This was a retrospective study based on data from 135 patients who reported to the Department of Implantology, Saveetha Dental College and Hospitals, Chennai, India between March 2020 and March 2021, obtained from the hospital records. Demographic data including age and gender and cone-beam computed tomography (CBCT) was collected and further analysed, recorded in Microsoft Excel software and subjected to statistical analysis using IBM SPSS statistics analyser version.23.0. Results and discussion: The overall mean value of the thickness of the Schneiderian membrane was 1.69± 1.54 mm. Among the 135 patients, 60.74% were males and 39.26% were females. Among the different age groups, 34.81% were of the 26-35 years age group, followed by 17-25 years with 25.19%, 36-45 years with 19.26%, 46-55 years and 56-65 years with 10.37% each.Conclusions: Within the limitations of the study, it was observed that the thickness of the Schneiderian membrane in young aged adults was lower, compared with the other age groups. As to gender, males seemed to have a thicker membrane than females.
