Superselective embolization for active colonic diverticular hemorrhage is safe and effective and should be considered as a first line treatment if possible and available. The procedure could act as a bridge to a subsequent more definitive elective surgery or be definitive as seen in over 50% of our patients over a period of 40 months.
Mandible fractures are a common occurrence in patients who have sustained blunt facial trauma. The commonest unilateral fracture of the mandible involves the subcondylar region, while the most common bilateral fractures occur at the condylar heads. Previous epidemiological studies have shown that fractures in and around the condylar region to be the most frequent. The shape of the mandible neck predisposes to intrinsic biomechanical weakness and makes this area particularly vulnerable to breaking. 1 The maxillary artery lies in close relation to the medial cortex at the subcondylar portion Keywords ► subcondylar fractures ► maxillary artery injury ► maxillary artery pseudoaneurysm ► mandible artery hemorrhage in mandible fractures
AbstractMandible fractures commonly occur in patients who have sustained blunt facial trauma, and the subcondylar region is the most frequently fractured due to its intrinsic biomechanical weakness. The maxillary artery lies in close relation to the medial cortex of the subcondyle and is vulnerable to injury by the sharp edges of the fracture fragments during the initial trauma or during operative fracture reduction. Maxillary artery injuries and subcondylar fractures may be an underdiagnosed phenomenon. Yet, this is of clinical significance as the maxillary artery caliber is usually of significant caliber and may lead to substantial hemorrhage. Surgical access to the artery for hemostasis is challenging and is further compounded by small surgical incisions usually undertaken for fracture fixation, obscuring of the artery by the overlying fracture fragments, and vessel retraction following its transection. In cases where maxillary artery injury is suspected, an open surgical approach may be favored over an endoscopic one. The authors illustrate a case in which brisk hemorrhage from the maxillary artery encountered during a preauricular approach to fixation of the mandible subcondyle was successfully controlled with temporary pressure on the external carotid artery through a neck incision and direct ligation of the lacerated maxillary artery. The authors then discuss diagnosis and treatment of such maxillary artery injuries and propose a novel diagnostic and treatment algorithm.
Only 9 cases of infraorbital nerve schwannoma have been described in literature, and the sublabial intraoral incision was attempted in only 1 case. The authors describe a rare case of an extraosseous schwannoma arising from the infraorbital nerve that presented as a cheek lump, its workup, its differentials, its treatment, and a review of literature. The use of a preoperative computed tomographic scan permitted the use of a sublabial intraoral incision with good visual access to the lesion and facilitated its complete extirpation without incurring external scars.
Concomitant maxillofacial, laryngeal and cervical spine injuries may occur after high-energy accidents. Although this presentation is uncommon, the multiple injuries may compromise airway, breathing, circulation, and neurologic function. We identified 8 adult trauma patients admitted to the National University Hospital with the concomitant injuries. We reviewed the patient data and existing literature to identify the important factors that must be considered for management. Seven resulted from high velocity accidents, whereas 1 was assaulted. An algorithm that prioritizes in-tandem diagnosis and acute management of the adult trauma patient with maxillofacial, laryngeal, and cervical spine trauma was developed. The first priority is to assess airway, breathing, and circulation with cervical spine immobilization. Early diagnosis of patients with severe laryngeal injury, confirmation by video endoscopy, and establishing a surgical airway prevents airway obstruction or even a laryngotracheal dissociation. Urgent computed tomography scans of the head and neck are essential for definitive diagnosis and surgical planning for the 3 injuries. Prudent sequencing of surgery is important to avoid complications and to achieve better functional outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
