Inter-foraminal implant placement poses a risk to the sublingual artery as it enters the mandibular midline lingual foramen. Lack of consensus on the source of this artery poses a dilemma to surgeons during management of haemorrhagic episodes. Determination of the exact source of this artery is therefore pivotal.
This was a cross-sectional descriptive study involving 34 adult human cadavers. The facial and lingual arteries were followed from the external carotid artery to determine whether they terminated as the sublingual artery. Statistical significance tests were done using the Mann-Whitney U test and Pearson product-moment correlation.
There were 30 (88.2 %) males and 4 (11.8 %) females (male/female = 15:2) aged between 25 and 40 years. The origin of the sublingual artery was mainly from the lingual artery (73.5 %), the submental artery (17.6 %), or an anastomotic branch from the two arteries (8.9 %). The mean distance between the mandibular midline lingual foramen (MMLF) and the inferior border of the mandible was 15.58 mm (range 11.03-19.62 mm). The mean thickness of the mandible at the level of the MMLF was 10.89 mm (range 8.00-12.91 mm). No statistically significant difference was found between the two genders with regard to the morphometric measurements.
The sublingual artery that enters the MMLF was found to be the sublingual artery as either a branch of the lingual artery (73.5 %), the submental artery (17.6 %) or an anastomosis of the lingual and submental arteries (8.9 %).
椎间孔间植入物放置对舌下动脉进入下颌骨中线舌孔时构成风险。关于该动脉来源缺乏共识,这给外科医生在处理出血情况时带来了两难困境。因此,确定该动脉的确切来源至关重要。
这是一项横断面描述性研究,涉及34具成年人体尸体。从颈外动脉追踪面动脉和舌动脉,以确定它们是否作为舌下动脉终止。使用曼-惠特尼U检验和皮尔逊积矩相关进行统计学显著性检验。
有30名(88.2%)男性和4名(11.8%)女性(男/女 = 15:2),年龄在25至40岁之间。舌下动脉的起源主要来自舌动脉(73.5%)、颏下动脉(17.6%)或这两条动脉的吻合支(8.9%)。下颌骨中线舌孔(MMLF)与下颌骨下缘之间的平均距离为15.58毫米(范围为11.03 - 19.62毫米)。MMLF水平处下颌骨的平均厚度为10.89毫米(范围为8.00 - 12.91毫米)。在形态测量方面,两性之间未发现统计学显著差异。
发现进入MMLF的舌下动脉是作为舌动脉分支(73.5%)、颏下动脉分支(17.6%)或舌动脉与颏下动脉吻合支(8.9%)的舌下动脉。
