This study aimed to evaluate the clinical outcomes of marsupialization in jaw cystic lesions and to determine the optimal timing for secondary enucleation. A total of 20 patients (15 males, 5 females; mean age: 47.40±11.74 years) underwent marsupialization with a mean duration of 62.51±31.17 weeks. Changes in the number of involved teeth, the need for root canal treatment or extraction, and recurrence after final surgery were assessed. Lesion size was measured using serial panoramic radiographs and CT images. On average, 46.48% of involved teeth were preserved after marsupialization. No injury to adjacent anatomical structures was observed following definitive enucleation. At 24 weeks, lesions showed a mean reduction of 61.78±15.17% on panoramic radiographs and 54.52±17.54% on CT (P<0.05), with the most significant shrinkage occurring around 18.37 weeks. No statistically significant correlation was found between shrinkage timing and patient age, lesion size or volume, pathological type, lesion site, or number of affected teeth. Marsupialization is a reliable conservative treatment option that facilitates tooth preservation and minimizes structural damage. Notably, lesion shrinkage peaked between 16 and 24 weeks, suggesting that delaying secondary surgery until after this period may enhance outcomes by promoting bone regeneration and increasing the potential for tooth preservation.
Abstract
This study aimed to evaluate the clinical outcomes of marsupialization in jaw cystic lesions and to determine the optimal timing for secondary enucleation. A total of 20 patients (15 males, 5 females; mean age: 47.40±11.74 years) underwent marsupialization with a mean duration of 62.51±31.17 weeks. Changes in the number of involved teeth, the need for root canal treatment or extraction, and recurrence after final surgery were assessed. Lesion size was measured using serial panoramic radiographs and CT images. On average, 46.48% of involved teeth were preserved after marsupialization. No injury to adjacent anatomical structures was observed following definitive enucleation.

No statistically significant correlation was found between shrinkage timing and patient age, lesion size or volume, pathological type, lesion site, or number of affected teeth.
