Abstract

OBJECTIVE

To investigate the relationship between anatomic characteristics of lingual artery and midline glossectomy, for the purpose of increasing operative safety.

METHODS

(1) 16 extraoral dissections of the submandibular region were performed on 8 human cadavers and to observe the origin and distribution of lingual artery. (3) The lingual artery was divided into three segments, and the length and adjacent organs were observed and measured.

RESULTS

The whole length of lingual artery was (92.88 +/- 13.53) mm; At points of foramen cecum of the tongue, 5 mm and 10 mm prior to foramen cecum, 10 mm behind foramen cecum, and at adjacent part between root of the tongue and epiglotic vallecula, the distances between lingual artery and midline of the tongue were separately measured. The distances were (11.00 +/- 4.95) mm, (8.56 +/- 3.51) mm, (7.78 +/- 3.15) mm, (13.00 +/- 3.28) mm, (15.22 +/- 3.11) mm. The distances between lingual artery and the surface of tongue were (21.4 +/- 5.59) mm, (22.11 +/- 6.74) mm, (22.56 +/- 7.81) mm, (16.56 +/- 5.57) mm, (2.56 +/- 0.73) mm respectively.

CONCLUSION

During the midline glossectomy, the lingual artery is easier to be damaged at the position where the root of tongue adjoining epiglottic vallecala. The operation should be done within 10 mm below the surface, 7 mm lateral to the midline, to avoid the damage of lingual artery.

摘要

目的

探讨舌动脉的解剖学特点与中线舌切除术之间的关系，以提高手术安全性。

方法

（1）对8具尸体进行16次下颌下区的口外解剖，观察舌动脉的起源和分布。（3）将舌动脉分为三段，观察并测量其长度及毗邻器官。

结果

舌动脉全长为（92.88±13.53）mm；分别在舌盲孔处、舌盲孔前5mm和10mm处、舌盲孔后10mm处以及舌根与会厌谷相邻处，测量舌动脉与舌中线的距离，分别为（11.00±4.95）mm、（8.56±3.51）mm、（7.78±3.15）mm、（13.00±3.28）mm、（15.22±3.11）mm。舌动脉与舌表面的距离分别为（21.4±5.59）mm、（22.11±6.74）mm、（22.56±7.81）mm、（16.56±5.57）mm、（2.56±0.73）mm。
