PURPOSE: To compare the preoperative signs and symptoms with the histologic diagnosis and postoperative healing at 12 months for 178 @entity1548 . MATERIALS AND METHODS: A total of 152 @entity1 who had undergone periapical surgery from 2005 to 2008 were studied. The study included @entity1 presenting with signs and symptoms before periapical surgery with a sufficient tissue sample (periapical lesion) for histologic analysis and a minimal follow-up of 12 months. The signs and symptoms present in the soft tissues at the initial examination were recorded. The histologic analysis established the diagnosis as @entity738 , cyst, or scar tissue. The postoperative healing at 12 months was evaluated according to the criteria of von @entity23019 and Kurt. RESULTS: Of the 152 @entity1 , 147, with 178 @entity1548 , were included in the present study. No significant relationship was found between the preoperative signs and symptoms, lesion type, and evolution. However, scar tissues were asymptomatic in 78.1%, and 36.4% of @entity738 were @entity158 . Of the 8 cysts, 50% were asymptomatic and 50% caused @entity158 . @entity82 created no soft tissue alterations in 68.7%. @entity738 had fistulized in 31.7%, and 75% of cysts had produced no alterations. The lesions with swelling had worse healing, and those with no soft tissue alterations had better postoperative healing. CONCLUSIONS: Chronic @entity1548 ( @entity738 , @entity8650 ) are usually asymptomatic and do not create soft tissue alterations. However, they can deteriorate, producing @entity158 and fistulization. Worse postoperative healing was observed for lesions with swelling, although the difference was not significant.
