Lingual Perimandibular Vessels Associated with Life-Threatening Bleeding: an Anatomic Study
Mardinger.qxd 1/25/07 2:55 PM Page 127 Lingual Perimandibular Vessels Associated with Life-Threatening Bleeding: An Anatomic Study Ofer Mardinger, DMD1/Yifat Manor, DMD2/Eitan Mijiritsky, DMD3/Abraham Hirshberg, MD, DMD4 Purpose: To describe the anatomy of the lingual perimandibular vessels and emphasize the distance to the bone. Materials and Methods: The hemifacial lower third was dissected in 12 human cadavers. The blood vessels in the floor of the mouth were exposed using sagittal incisions at the canine, mental foramen, and second molar areas. Results: The diameter of the dissected vessels ranged from 0.5 to 3 mm (mean, 1.5 mm). Most vessels were found superior to the mylohyoid muscle in the canine area and beneath the muscle in the mental and second molar areas. The smallest median vertical distance from blood vessel to bone was in the canine area (14.5 mm), followed by the mental foramen area (15.5 mm) and the second premolar area (19 mm). The median horizontal distance of the vessels from the lingual plate was 2 mm at the canine and second molar areas and 4 mm at the mental area. Discussion: Lingual plate perforation, especially anterior to the canine area, can easily injure blood vessels in the floor of the mouth and cause life-threatening hemorrhage following implant placement. Bleeding can occur when the mandibular lingual plate is perforated. Care should be taken to recognize situations where this complication may occur. Conclusions: Based on the study of human cadavers, it appears that vessels in the floor of the mouth are sometimes in close proximity to the site of implant placement. -
Branches of the External Carotid Artery of the Dromedary, Camelus Dromedarius Artery Origin Course Distribution
Table 3.4: Branches of the External Carotid Artery of the Dromedary, Camelus dromedarius Artery Origin Course Distribution Originates at the bifurcatio of the occipital artery from the common carotid artery. Superficial Occipital region, lateral face, pharynx, Common Carotid External Carotid course is throughout occipital and posteroinferior tongue, hyoid musculature, and Artery facial regions; deeper course is throughout sublingual glands. pharyngeal, lingual, and hyoid regions. The proper occipital artery is the first dorsal branch of the ECA. It arises near the caudal border of the wing of the atlas, traverses the atlantal fossa, and then splits into: 1. Multitude External Carotid of muscular branches; 2. Anastomosis with Collateral circulation with vertebral Occipital Artery vertebral artery (through alar foramen); 3. arteries; neck and occipital muscles Superior termination continues to course toward the external occipital protuberance, supplying the parenchyma of the occipital region inferior to and surrounding the foramen magnum. Variable origin: from the ECA or the "ascending pharyngeal." Condylar and ascending pharyngeal External Carotid may share a short common trunk. An anterior Artery (var: branch of the condylar artery follows the Inferior meninges and inferolateral Condylar Ascending hypoglossal nerve into the hypoglossal canal to occipital region. Pharyngeal) supply the inferior meninges. A posterior branch of the condylar provides collateral circulation to the occipital region.

Hanai) (With one table, two textfigures and 16 figures in 4 plates) -Received for Publication, November 1, 1978- Key Words : Floor of mouth, Artery, Corrosion cast, Comparative anatomy Summary. The arterial distributions in the region of the floor of the mouth in the rat were studied by means of the acryl plastic injection method. 1. The region and its related tissues were supplied mainly by branches of the sub- lingual artery of the facial, and partly by branches of the tonsillar of the facial and branches of the ascending palatine of the lingual. 2. Branches of the sublingual artery were the submandibular lymph node branch, the muscular branches, the submental branch, the mandibular transversal branches, the mucous branch, the genioglossal branches, the preincisive branch, the retroincisive branch and the alveolar branch. 3. Branches of the tonsillar artery were the mucous branch and the mylohyoid branches. 4. A forward branch and small twigs of the ascending palatine were distributed to the posterior small part of the region. 5. Between the above-mentioned branches and the lingual artery, any marked anastomoses were not observed. Preface structed, and that, therefore, the sufficient observation has been difficult by using It is very important to survey the the common dissection method. arterial distribution in the oral region in This paper was undertaken to reveal the rat since this animal is the most the detailed arterial distribution and commonly used in many kinds of ramification of the distributing arteries medico-dental research. -

An Investigation of Virgin Variation of Branching Pattern of ECA and CCA: a Case Report
Case report http://dx.doi.org/10.4322/jms.096715 An investigation of virgin variation of branching pattern of ECA and CCA: a case report RAJANI, S.* Department of Anatomy, All India Institute of Medical Sciences, Rishikesh, Uttrakhand, India *E-mail: [email protected] Abstract Introduction: Common carotid and its two major branches, external and internal carotid arteries form arterial network for blood supply in the head and neck region. Variations in configuration and branching pattern of these arteries change the irrigation pattern and complicate the identification of specific arteries during surgical intervention coupled with imagery interpretation for diagnosis. Though handful variations have been documented yet there is strong need to report unusual, new and virgin organization of configuration and branching pattern in these arteries. Case Report: During dissection of head and neck region, anomalous branching pattern consisting of bilateral trifurcation/quadrification of common and external carotid arteries and abnormal trifurcation of distal external carotid artery was observed. Conclusion: Lack of knowledge of these variants in branching configuration may lead to unfortunate differential diagnosis and iatrogenic complications. Keywords: common carotid, external carotid artery, quadrification, trifurcation, branching pattern. 1 Introduction The common carotid artery (CCA) bifurcating into CCA bifurcated into ECA, ICA and also gave off superior external and internal carotid arteries at the level of superior thyroid artery bilaterally in this cadaver at 2 cm above thyroid border of thyroid cartilage in carotid triangle (STANDRING, cartilage in right (Figure 1R) and just below the level of angle 2008) plays major role for blood supply to the head and neck of mandible at 2.5 cm above the upper border of thyroid region. -
Percutaneous Puncture of the External Carotid Artery Or Its Branches After Surgical Ligation
Percutaneous Puncture of the External Carotid Artery or Its Branches After Surgical Ligation Y. Pierre Gobin, Anne Pasco, Jean-Jacques Merland, Armand A . Aymard, Alfredo Casasco, and Emmanuel Houdart PURPOSE: To describe the technique and results of percutaneous puncture of the external carotid artery or one of its branches distal to a surgical arterial ligation. METHODS: Forty-three patients underwent 64 embolization attempts by percutaneous arterial puncture distal to an external carotid artery ligation. The punctured arteries were the trunk of the external carotid artery in 31 patients, the internal maxillary artery in nine, the facial artery in nine, the lingual artery in eight, the occipital artery in four, and the superficial temporal artery in three. RESULTS: In 64 attempts 57 were successful in one session, six were successful in two sessions, and one failed. Puncture-related complications were eight spontaneously resolving hematomas and six asymptomatic punctures of the internal carotid artery. CONCLUSION: After surgical ligation of the external carotid artery or its branches, arterial puncture above the ligation allowed selective catheterization and endovascular occlusion of vascular lesions.

The variations in the branching pattern are also essential to avoid complications with catheter insertion of carotid arteries in various procedures and pre-operative angiography. The external carotid artery is an important route for administration of anticancer drugs for head and neck cancer, so the knowledge of anatomy of branching pattern of external carotid artery is clinically important. Materials and Methods: Total 30 external carotid arteries were included in the present study. The dissection of the external carotid artery was carried in the dissection hall of the Anatomy Department, Manipal College of Medical Sciences. When all the branches and course of the external carotid artery was visible, variations was noted. The length of artery was measured with the help of thread, scale and vernier calliper. All the data were analyzed with Microsoft Excel 2007 software and represented as mean and standard deviation. -
