Evaluation of Mastoid Pneumatization Using Cone-beam Computed Tomography: A Retrospective Study

Research output: Contribution to journalArticlepeer-review


Aim: To evaluate mastoid pneumatization in cone-beam computed tomography (CBCT) scans. Materials and methods: The prevalence of mastoid pneumatization was evaluated among a sample of 300 CBCT scans in this retrospective study. Relevant details, such as age and gender were recovered from the institutional database. The scans were evaluated for pneumatization of the mastoid process and correlated with gender and age. Results: About 30.83% of the scans showed pneumatization of the temporal region of the temporomandibular joint (TMJ). No significant correlation of pneumatization with age and gender was found. Conclusion: Excessive pneumatization of mastoid can involve temporal regions of the TMJ in a significant number of populations. This study also marks the usefulness of CBCT in evaluating the temporal bone of the skull. Clinical significance: Cone-beam computed tomography (CBCT) scan is a very useful tool in delineating temporal bone anatomy with high precision and lower radiation and cost. This study helps in the evaluation of extensive pneumatization of mastoid extending to TMJ, which can act as the path of least resistance to the spread of infections and tumors and can also pose surgical challenges.
