壁性成釉细胞瘤术后追踪观察

Postoperative follow-up of mural ameloblastoma

目的 研究影响壁性成釉细胞瘤术后复发因素及刮治术后复发病例观察。方法 对44例壁性成釉细胞瘤患者术后观察 1年～ 2 5年 4个月 ,平均 5年 7个月。结果 ①刮治术后复发 (8/35 )多于根治术后复发 (1/9) ;②肿瘤生长呈壁内型 (4 /7)和混合型 (3/4 )刮治术后复发明显多于腔内型术后复发 (0 /15 ) ;③蜂房型 (3/3)刮治术后复发明显多于单房型 (1/2 0 ) ;④刮治术后 2年内肿瘤易出现复发 (7次 /5例 ) ;⑤刮治术后复发者再次刮治仍有再复发倾向。结论 ①X线表现呈蜂房型者应做根治手术 ;②刮治术后病理呈壁内型或混合型生长方式者应重视定期复查 ;③刮治术后病例应常规定期复查 5年。

Objective To investigate the determinant of recurrence in mural ameloblastoma Methods Forty four cases of mural ameloblastoma were followed up postoperatively for 1 year to 25 years and 4 months (mean of 5 7 years) Results ① The recurrence is more likely to recur in curettage group (8/35) than in radical surgery group (1/9); ②The recurrence is more in intramural (4/7) and complex (3/4) group more than in intracavity group (0/15) after curettage treatment; ③Those with honeycomb appearance (3/3) recurred more than those with unilocular appearance (1/20); ④It recurred mostly within 2 years postoperatively (7 recurrences in 5 cases); ⑤Recurrent cases were susceptible to repeated recurrence after recurettage Conclusions ①The lesion with honeycomb appearance should be treated with radical surgery; ② The follow up should be emphasized for those with intramural or complex features; ③ The curettage cases should be followed routinely for 5 years postoperatively
