Total Aplasia of the Paranasal Sinuses: A Rare Presentation

Paranasal sinuses are air-filled cavities located within the bones around the nasal cavity. Abnormalities and anatomical variations of the paranasal sinuses are commonly seen. Various degrees and combinations of paranasal sinus aplasia and hypoplasia cases have been reported. However, very few cases of total paranasal sinus aplasia have been reported to date. We herein describe a total paranasal sinus aplasia case detected incidentally in a 22-year-old male patient without any disease affecting the skeletal system.
