A Stafne bone cyst is usually an incidental radiologic finding that most often appears as a unilocular lesion with benign cortical thinning in a characteristic location near the angle of the mandible, immediately beneath the inferior alveolar nerve canal.1 It can occur in any age group but is most common in men in their fifth to seventh decades of life. The prevalence of the Stafne defect within the population ranges from 0.1% to 0.48%, depending on published studies.2 Patients are typically asymptomatic at the time of presentation. The defects are most often unilateral but bilateral presentations have been reported.3,4
