It was suggested that the accessory neurovascular foramina of the mandible might be of significance in relation to the effectiveness of local anesthesia following the routine inferior alveolar nerve block.
To investigate the incidence of neurovascular foramina over the lingual surface of the mandible in South Indian population.
The study was conducted at the department of anatomy.
The study included 67 human adult dry mandibles, the exact ages and sexes of which were not known. The location and number of neurovascular foramina were topographically analyzed.
Descriptive statistics.
The foramina were observed in 64 mandibles (95.5%) and were often multiple in most of the cases. They were located between the two medial incisors in 8 mandibles (1.9%), between the medial and lateral incisor in 34 mandibles (50.7%; 25-bilateral; 7-right; 2-left), between the lateral incisor and canine in 7 mandibles (10.4%; 2-bilateral; 3-right; 2-left), between the canine and first premolar in 6 cases (8.9%; 3 on each side). Foramina were also present around the genial tubercle in 56 mandibles (83.6%). Among them, 52 mandibles showed a single foramen just above the genial tubercle, 34 mandibles had foramina below the tubercles, 13 mandibles had foramina on the right side of genial tubercle and 17 were having on the left side.
Since the anatomical details of these foramina are important to various fields of dentistry and oncology, the present investigation was undertaken. The clinical significance and implications are emphasized.
有人提出，下颌骨的副神经血管孔可能与常规下牙槽神经阻滞局部麻醉的效果有关。
调查南印度人群下颌骨舌面神经血管孔的发生率。
该研究在解剖学系进行。
该研究包括67具成年人类干燥下颌骨，其确切年龄和性别不详。对神经血管孔的位置和数量进行了地形学分析。
描述性统计。
在64具下颌骨（95.5%）中观察到这些孔，大多数情况下孔为多个。它们位于8具下颌骨（1.9%）的两颗中切牙之间，34具下颌骨（50.7%；25具双侧；7具右侧；2具左侧）的中切牙和侧切牙之间，7具下颌骨（10.4%；2具双侧；3具右侧；2具左侧）的侧切牙和尖牙之间，6例（8.9%；每侧3个）的尖牙和第一前磨牙之间。56具下颌骨（83.6%）的颏结节周围也有孔。其中，52具下颌骨在颏结节上方有单个孔，34具下颌骨在结节下方有孔，13具下颌骨在颏结节右侧有孔，17具下颌骨在左侧有孔。
由于这些孔的解剖细节对牙科和肿瘤学的各个领域都很重要，因此进行了本研究。强调了其临床意义和影响。
