Solitary maxillary or mandibular bone cysts are rare benign lesions. They are usually localized in the mandible of young men. In some cases, a traumatic risk factor can be documented.
A young 13-year-old female patient consulted in the orthodontics unit. An orthopantomogram showed a large cystic lesion in the ramus and posterior part of the left mandible corpus. No reossification of the cavity was observed one year after curettage. A second curettage was performed combined with PRF filling. Six months later, the cavity was completely reossified.
Curettage is the first line treatment of isolated cystic lesions and generally followed by complete reossification of the cavity. Incomplete healing is observed in 20% of the cases. PRF may induce the healing of non-reossified cystic cavity by supplying local growth factors.
孤立性上颌骨或下颌骨囊肿是罕见的良性病变。它们通常位于年轻男性的下颌骨。在某些情况下，可以记录到创伤性危险因素。
一名13岁年轻女性患者在正畸科就诊。全景曲面断层片显示左下颌骨升支及体部后部有一个大的囊性病变。刮除术后一年，未观察到腔隙的再骨化。进行了第二次刮除术并联合PRF填充。六个月后，腔隙完全再骨化。
刮除术是孤立性囊性病变的一线治疗方法，通常随后腔隙会完全再骨化。20%的病例观察到愈合不完全。PRF可能通过提供局部生长因子诱导未再骨化的囊性腔隙愈合。
