Arteriovenous malformation (AVM) of the head and neck is a rare phenomenon, more so when it is an extracranial AVM like the auricle. AVMs are caused by genetic mutations. Most are probably present in the subclinical form at birth and then evolve; some may arise postnatally or during adolescence or get aggravated by precipitating factors like trauma, infection or hormonal influence like puberty or pregnancy. Once diagnosed, the feeding vessels have to be identified using radiological investigations. They are then embolised via means of percutaneous embolisation and surgical resection.
Schwannomas of the eighth nerve are common, usually found in syndromic association with neurofibromatosis-2. The occurrence of seventh nerve schwannoma, especially in its extratemporal course, is very rare. Here, we present a case report of an extratemporal facial nerve schwannoma diagnosed preoperatively with cytopathology and postoperative histopathologic confirmation. Histopathology provides the confirmatory diagnosis in such cases. An atypical diagnosis of neural schwannomas should be kept in mind when facial palsy is clinically encountered in the absence of any other aetiological factors.
The Neck is a cylindrical structure containing vital neurovascular and visceral structures tightly packed in a relatively small volume. Mortality rate increases when there is an injury to vascular structures especially the carotid artery, surrounded by other vital neurovascular structures; injuring the neck leads to devastating morbidity when compared to other injuries. With increased awareness of screening techniques and improved detection rates, there is an urge in opting for selective neck exploration and initial aggressive antithrombotic therapy for blunt carotid artery injuries. Here we report a case of a 20-year-old male, with a lacerated injury of the right side of the neck causing transection of the right internal jugular vein, grade 4 (Denver classification) blunt carotid injury, along with cervical vertebral fractures without neurological deficits. The patient underwent emergency surgical neck wound exploration, flush ligation of transacted Right Internal Jugular Vein, and conservative management for blunt carotid artery injury using anti platelets (Aspirin and Clopidogrel) avoiding any immediate neurological deficits. Whenever lacerated neck wounds are evaluated, the chance of blunt injury to the carotid is to be borne in mind and such an injury can be managed with double antiplatelet therapy, if there are no demonstrable neurological deficits.
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.
