Maxillary Artery: Anatomical Landmarks and Relationship with the Mandibular Subcondyle

Abstract

The maxillary artery can be injured during surgical procedures performed in the temporomandibular region. Its relationship with the subcondylar portion of the mandible varies.

Anquilosis de ATM: Riesgos Anatómicos y Potencialidad del Sistema Piezoeléctrico

“…Topográficamente, las estructuras vasculares asociadas a la ATM están representadas por la arteria temporal superficial y la arteria facial transversa en el aspecto lateral del cuello condilar y también por la arteria maxilar y el plexo pterigoide en el aspecto medial (Orbay et al, 2007). La masa anquilótica impide un reconocimiento normal de las estructuras debido al crecimiento de tejido óseo y fibroso junto a la base de cráneo, de forma que otras estructuras vasculares y nerviosas pueden estar próximas al área de la masa óseo, de forma que extensas masas son capaces de comprometer forámenes y estructuras vasculares mediales como la arteria carótida interna (Eller et al, 2012).…”

Divided and reunited maxillary artery: developmental and clinical considerations

“…An anomalous or unpredictable course of the maxillary artery or one of its many branches may increase that risk of iatrogenic injury. As described by Orbay et al (2007), accidental arterial puncture can occur during procedures to the subcondylar portion of the mandible, such as internal fixation of mandibular fracture, mandibular osteotomy, and temporomandibular joint arthroplasty. It is also placed at risk during percutaneous blocks of the pterygopalatine ganglion and branches of the trigeminal nerve for both routine dental procedures and ablative treatment of intractable craniofacial pain syndromes (e.g., trigeminal neuralgia and cluster headache).…”

An extensive retropharyngeal haematoma associated with pyramidal fracture: A case report

“…7 However, facial artery injuries have also been reported in trauma cases with an incidence ranging from 1 to 11%. 5 Oronasal bleeding is a common physical finding following injury to the maxillary artery and its branches.…”

“…2 Maxillary artery injury can result in uncontrollable bleeding because it branches from the external carotid artery (ECA), an easily damaged artery following facial trauma. 7 If pressure packing and haemostatic agents do not effectively control bleeding, ECA ligation or transcatheter arterial embolization (TAE) may be employed. 2,5,7 We report herein a case of maxillary artery injury with a rare underlying mechanism.…”

“…7 If pressure packing and haemostatic agents do not effectively control bleeding, ECA ligation or transcatheter arterial embolization (TAE) may be employed. 2,5,7 We report herein a case of maxillary artery injury with a rare underlying mechanism. We believe that this type of injury may present diagnostic challenges for physicians in emergency settings.…”
