[Applied anatomical study of the lingual nerve].
The lingual nerve and its adjacent structures were observed and measured on 32 adult cadavours. Its length was 69.7 mm and it was divided, bounded by the internal pterygoid muscle, into three segments and the length and diameter of them were respectively measured. According to its relationship with the lingual nerve, the submandibular ganglion can be classified into fusion type (being 46.9%) and free type (being 53.1%), and its superoinferior and transeversal diameters were separately measured to be 2.7 and 2.9 mm. The lingual nerve and its lingual branches were closely related to submandibular duct and there were two intersects. The relation and clinical significance of the third segment of lingual nerve and its neighbor structures were studied.
