Background: Since the development of three-dimensional (3D) cone beam computed tomography (CBCT), it has been uniquely integrated within the field of dentistry and is often utilized in treatment of cleft/craniofacial patients. With increased detail and scope of interpretation, this new technology legally and ethically commits the ordering clinician to greater responsibility for any incidental findings, which is likely to see an increase in frequency. Since the advent of CBCT, only one study has reported the incidence of incidental findings in pre-ABG cleft/craniofacial patients during the period of mixed dentition. We present our experience.
Methods: In a retrospective study at our institution (2012-2016), CBCTs of non-syndromic cleft lip/palate patients preparing for alveolar bone graft (n=111) were independently reviewed by two orthodontists and a neuroradiologist. Incidental findings were recorded. Descriptive statistics were applied.
Results: Overall, 96% of patients had some incidental finding (38% dental; 47% paranasal sinuses; 19% middler/inner ear). The maxilla was the most common (87%) anatomic location for incidental findings (i.e. ectopic eruption, missing teeth). The majority of patients had more than one anatomic area affected (69%).
Conclusion: CBCT has become an increasingly accessible and prevalent technology. With increased diagnostic information, the clinician has a greater responsibility to assess for incidental findings. To our knowledge this is the first report about incidental findings in the cleft population. Unsurprisingly, the cleft population has a high incidence of incidental findings.
