Nasal turbinate is a normal structure inside the nasal cavity, located in the lateral wall of the nasal cavity on both sides, which can be divided into the upper turbinate, middle turbinate and lower turbinate. The inferior turbinate is the largest, an independent bone piece, the posterior end from the pharyngeal opening of the Eustachian tube is only 1-1.5cm, when various reasons cause the inferior turbinate enlargement, it can cause the nasal cavity blockage, can also cause secretory otitis media occurs. Below the inferior turbinate, there is the inferior nasal passage with the opening of the nasolacrimal duct. The middle turbinate is a sieve bone structure, and a fracture of the middle turbinate may lead to cerebrospinal fluid rhinorrhea. The middle turbinate is an important anatomical landmark for endonasal sieve sinus surgery. Between the middle and inferior turbinate is the middle nasal passage with the anterior set of sinus openings and the presence of the sinonasal complex, and functional nasal endoscopic surgery is primarily performed in this region. The superior turbinate is the smallest turbinate and is also a sieve bone structure, with the pterygoid sieve crypts at the posterior end posteriorly above the pterygoid sinus openings.
