case_images: A, orthopantomogram revealing a cystic lesion between teeth 23-26. B, preoperative orthopantomogram in year 2007. E, Postoperative orthopantomogram in year 2007. C, Postoperative orthopantomogram showing adequate removal of the lesion in 2010. D, orthopantomogram obtained in 2017 showing no signs of recurrence and good bone remodelling. E, orthopantomogram obtained in 2019. It is clear to see that the situation hasn't changed during the years 2017 and 2019.

case_images: The edges of the lesion appeared sclerosed (Fig. 1).
case_images: A, Preoperative Computer tomography in 2007 showed a large distension within the left sinus maxillaris in size of 3,4 x 3,2 x 2 cm. Signs of sclerosis are clear within the marginal edges of the cystic lesion. B, Computer Tomography during a follow up appointment revealed cystic changes in operated region, prompting another operative removal of the recurrent cyst. C and D, Computer Tomography taken in 2017 and 2019 showed no signs of recurrence and good bone remodeling.
