Which is an independent bone?

Nasal turbinates are functionally impoant structures that extend from the lateral nasal walls to nasal cavities. The middle, superior and, in some cases, supreme turbinates are pa of the ethmoid bone, while the inferior turbinates are a pair of independent bones. Lateral nasal wall anomalies are generally incidentally detected asymptomatic lesions. The most common variation of the lateral nasal wall are pneumatizations of turbinates.
