Sublingual hematoma is a rare complication of oral anticoagulant use. Spontaneous sublingual hematoma secondary to hypertension is even rarer and their management remains enigmatic. We present such a case that we successfully managed conservatively along with a review of relevant literatures.
Ameloblastoma is a benign yet locally invasive odontogenic neoplasm, characterised by slow growth and painless swelling. The treatment for ameloblastoma varies from curettage to en bloc resection, with recurrence commonly occurring. The safety margin of resection is hence essential to avoid recurrence. Understanding the three-dimensional anatomy for reconstruction of mandibular defects after tumour resection often poses problems for head and neck surgeons. Historically, various autografts and alloplastic materials have been used in the reconstruction of these types of defects. Over time, advances in technology with computed tomography scanners and three-dimensional images enhance the surgical planning and management of maxillofacial tumours. The development of new prototyping systems provides accurate 3D biomodels on which surgery can be simulated, especially in cases of ameloblastoma, in which the safety margin is vital for the clinical outcome. The objective of this paper was to report a clinical case of employing these methodologies for reconstruction after an extensive mandibular resection. The clinical outcomes were observed. A case of follicular ameloblastoma of the mandible is depicted in the following paper, where a 3D biomodel was used throughout the surgery. A 3D printed patient-specific titanium implant was manufactured and placed intraoperatively for reconstruction. The treatment had satisfactory postoperative results without complications. Titanium implants being bioinert, customisable and easily workable, especially with the help of 3D virtual planning techniques, can be considered as ideal alloplastic materials for mandibular reconstruction.
BACKGROUND Pseudoaneurysm is very rare in Head Neck region. Psedoaneurysm or false aneurysm develops only from adventitia, lacking one or more of the layers of the vascular wall. Correct clinical diagnosis and management is challenging. CASE REPORT 19 years old male patient presented with a swelling in the left parotid region following trauma in the same region with the sharp end of a scissor. USG and Colour Doppler were suggestive of a A-V malformation. MRI and MR Angiogram showed it to be a pseudoaneurysm arising from superficial temporal artery. Superficial parotidectomy was done followed by ligation of superficial temporal artery. Aneurysm was subsequently excised. DISCUSSION Pseudoaneurysms are relatively rare in the external carotid system. It is most commonly seen in association with superficial temporal artery in external carotid system. Several anatomical factors predispose to such propensity. Imaging studies followed by surgical excision remains the treatment of choice. CONCLUSION Penetrative trauma in the head-neck region is not uncommon. Their exterior entrance may appear benign but deeper part may have significant and dangerous injuries. Any pulsatile mass that follows trauma in the head and neck regions might be a case of pseudoaneurysm.
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.
