[Evaluation of endoscopy-assisted precision minimally invasive treatment of mandibular bone cyst].

PURPOSE: To investigate the clinical effect of endoscopy-assisted curettage of mandibular bone cyst.

METHODS

A total of 80 patients with mandibular bone cyst treated in the First Affiliated Hospital of Bengbu Medical University from September 2021 to July 2023 were selected and divided into experimental group (n=43) and control group (n=37) according to treatment methods. The observation group was treated with endoscopy-assisted cyst curettage and secondary examination, while the control group was treated with traditional cyst curettage. The operation time, postoperative reaction, pathological fracture, nerve injury and recurrence were recorded in the two groups.

RESULTS

The operation time of the experimental group was (50.11±4.65) min, which was significantly longer than (44.89±4.38) min of the control group (P＜0.05). The degree of swelling and VAS pain scores in the experimental group were significantly lower than those in the control group on the 2nd and 7th days after operation (P＜0.05). There was no pathological fracture in the two groups. There was 1 case of nerve injury in the experimental group, which recovered 3 months after operation, and no recurrence was found in the 1-year follow-up. There were 3 cases of nerve injury in the control group, and all of them recovered within 3 to 6 months after operation. Two patients had recurrence during revisit.

CONCLUSIONS

Endoscopy-assisted curettage of mandibular bone cysts has the advantages of good surgical field, reducing injury and recurrence, and can improve the accuracy and safety of surgery, which is worthy of clinical application.
