Introduction: Endoscopy is widely recognized as a safe, convenient, and cost-efficient tool for examining and treating nasal ailments. The middle turbinate is an important landmark of the lateral nasal wall during endoscopy. Knowledge regarding the anatomy of the middle turbinate and its variations is beneficial to the endoscopic surgeons. Material and Methods: The shape and size of the middle turbinate were studied in hundred hemisected adult Indian cadaveric heads. Results: The middle turbinate is classified into three types according to the shape of its anterior border: Type 1 (38%), Type 2 (42%), and Type 3 (20%). The mean distance between the anterior attachment of the middle turbinate and the anterior attachment of the superior turbinate (MS) is 19.22 mm. The mean heights of the middle turbinate at its intersection with the anterior attachment (M1), the middle portion (M2), and at the posterior end (M3) of the superior turbinate are 12.83 mm, 9.14 mm, and 5.61 mm, respectively. Discussion and Conclusion: The study has described the anatomy of the middle turbinate with its clinical implications, especially in Type 1 and Type 3 middle turbinates, and precautionary measures should be taken while performing partial turbinectomy to avoid destabilizing the middle turbinate and to maintain patency of the middle meatus postoperatively. The documentation of these various types and their frequencies would be useful for the otorhinologists while performing endoscopy.
