The present case series report aims to demonstrate the outcomes of sinus augmentation under perioperative pathologic conditions of the maxillary sinus. In a preoperative assessment, two patients were diagnosed with mucous retention cysts and chronic maxillary sinus, respectively. In two other patients, postoperative maxillary sinusitis was diagnosed via crestal and lateral approaches after the sinus augmentation. All cases were managed with supplementary medical or surgical therapy to minimize further complications of sinus augmentation. In one patient who refused referral to the tertiary hospital for asymptomatic chronic maxillary sinus, the opacification in the maxillary sinus recurred 18 months after augmentation. However, the abnormality was asymptomatic and still under surveillance. Three other patients presented no further complication and with favorable outcomes of sinus augmentation. In conclusion, bone augmentation in the maxillary sinus demands proper perioperative management to obtain clinical improvement.
