ABSTRACT
BACKGROUND AND PURPOSE:
Early postoperative reactions occur following lateral sinus floor elevation (LSFE). This article radiographically describes, quantifies, and measures these early postoperative changes inside grafted maxillary sinus area. MATERIALS ANDMETHODS:
In 24 patients, 31 maxillary sinuses were performed using piezosurgery and grafted by bioceramic materials. Cone beam computed tomography was done preoperatively and then postoperatively, randomly, at either day 1 (n = 6), 2 (n = 11), 3 (n = 8), or 7 (n = 6) and at 6 months for all patients. Membrane thickening and subsequent swelling ratio, submucosal edema, and air bubbles inside grafted area were noted and measured. Inflammation was classified as mild, moderate, or severe.RESULTS:
Preoperative mean membrane thickness was 0.75 mm then following LSFE it significantly increased at days 1, 2, 3, and 7 and was respectively 2.36, 4.14, 6.05, and 6.63 mm. Mean swelling ratio significantly increased over time and was 11.37, 13.73, 16.34 and 35.78 at days 1, 2, 3, and 7, respectively. Submucosal edema height was noted in 24 cases. It had a mean value of 3.35 mm and increased significantly with time. Inflammation inside grafted area was mild in 7, moderate in 15, and severe in 9 of the cases. It significantly increased with time. Apical air bubble was present in 19 cases and had mean dimensions of 6.6 × 4.6 mm. No inflammatory signs were noted at 6 months.CONCLUSIONS:
Inflammatory reactions are always noted following LSFE and tend to increase with time reaching peak values at 7 days. All inflammatory changes significantly subsided at 6 months.Palavras-chave
