Abstract

Recently, with the increasing interests in the endoscopic nasal surgery, it is essential for practitioners to have detailed knowledges of the anatomical structures for the successful surgery. This study was undertaken to provide morphological information of the nasal turbinates as anatomical reference during endoscopic nasal surgery. A total of 43 adult cadaver heads were bisected midsagitally and evaluated morphometrically. The results were as follows: The highest nasal turbinatee were observed in 66.7% of the case. After removal of the mucosa, the distances from the akanthion to the anterior end of superior, middle, inferior nasal turbinate were 46.75 mm, 38.23 mm, 18.51 mm respectively. The distances from the akanthion to the posterior end of superior, middle, inferior nasal turbinate were 55.11 mm, 54.72 mm, 50.26 mm respectively. The lengths of the superior, middle, inferior nasal turbinate were 22.20 mm, 40.14 mm, 40.97 mm respectively. The detailed measurements of the nasal turbinates performed in this study may provide useful anatomical landmarks for the endonasal endoscopic surgery.
