Evaluation of the Effectiveness of Cryosurgery in Reducing the Recurrence of Peripheral Giant Cell Granuloma after Eradication

Evaluation of fate of Peripheral Giant Cell Granuloma after surgical removal and application liquid nitrogen by cotton stick.
The sample consisted of 26 patients with Peripheral Giant Cell Granulomas. The sample was divided into two groups: Group 1: 13 patients, liquid nitrogen was performed after surgical removal, and group 2: 13 patients, conventional surgical removal was performed. in both groups under local anaesthesia, 2-3 mm away from the edges of the lesion, covering all mucosal thickness up to the bone and curretage the exposed bone surface. liquid nitrogen was applied by cotton stick to half of this sample to examine the effectiveness of it in reducing the recurrence.
Injuries were distributed across ages, repeated in the third decade of life, and more frequent in males than females (the ratio was 53.8% for males). Injuries were more frequent in the mandible than in the maxilla and in the anterior than posterior region (the ratio was 46.2%). Most lesions were sessile (84.6%). Note that there is no association between application of liquid nitrogen by a cotton stick and its non-application after surgical removal in the reducing of recurrence of Peripheral Giant Cell Granuloma.
It is advisable not to apply cryosurgery by liquid nitrogen with a cotton stick after surgical removal of PGCG since it has not shown a significant benefit to reduce tumor reccurence.
