Unilateral secondary middle turbinate and ipsilateral bifid inferior turbinate with presence of uncinate process: Is it true bifid inferior turbinate?

Anatomical variations of the nasal turbinate, such as secondary middle turbinate (SMT) and bifid inferior turbinate (BIT), are sporadic. In most cases, SMT and BIT are generally bilateral. Moreover, the uncinate process is unusual in BIT because it is widely acknowledged that BIT could be an abnormality of the uncinate process.
