Yu H, et al. - Authors examined 15 cases who underwent 17 maxillary sinus augmentation surgeries to assess the clinical and histological consequences of the bone grafting and to present a modified surgical technique for removal of maxillary pseudocyst with simultaneous sinus floor elevation. They collected and analyzed bone biopsy samples at 6 months after surgery with mean percentages of mineralized bone, bone substitute, and nonmineralized tissue were 24.9% ± 18.1%, 14.4% ± 12.5%, and 60.1% ± 12.44%, respectively. They observed no recurrence of pseudocyst on radiographic testing proposing the recommended application of the technique in clinical practice for sinus augmentation.
