“…However, if the two ends are closed, the secluded space may lead to cyst formation or trigger infection and sinusitis. Sinusitis is a well‐described complication that might occur after sinus floor elevation (Hsu et al, 2022), and the formation of these secluded spaces should be considered as possible reason for sinusitis, together with mucosal perforation and biomaterial extrusion within the sinus cavity (Doud Galli et al, 2001; Testori et al, 2020; Urban et al, 2012). The experiments included in the present article were initially meant for other purposes, and the adhesion phenomenon was discovered during histological evaluation.…”

AimTo describe the histological events that occur after maxillary sinus floor elevation when the elevated and undetached sinus mucosa are in close proximity or in contact with each other.Materials and methodsFrom 76 rabbits, 152 elevated maxillary sinuses were analyzed histologically. Sites without adhesions were classified as “No proximity,” whereas the adhesion stages were divided into “Proximity,” “Fusion,” and “Synechia stages.” The width of the pseudostratified columnar epithelium and the distance between the two layers of the elevated and undetached sinus mucosae were measured at various standardized positions.ResultsThirty‐one sites presenting with adhesions were found. Twelve sites were in the proximity stage,” presenting cilia of the two epithelial layers that were shortened and interlinked within the mucous context. Hyperactivity of the goblet cells was also observed. In the other cases, the hyperplastic epithelium showed attempts to reach the contralateral mucosa. The 15 “fusion stage” sites presented regions with epithelial cells of the two mucosal layers that penetrated each other. Four sites presented “synechiae stages,” represented by bridges of connective tissue connecting the two lamina propria.ConclusionsClose proximity or tight contact between the elevated and undetached mucosa adhering to the bone walls might occur after maxillary sinus floor elevation. This induced hyperplasia of the epithelial cells and adhesion of the two layers until synechiae formation.
