Management of pseudoaneurysms of the internal maxillary artery derived from orthognathic surgery based on one case.

Purpose: The purpose of this article is to highlight the risk of pseudoaneurysms formation after orthognathic surgery, their clinical features and management.

Methods: A case report of a 24-year-old man who suffered a pseudoaneurysm of the internal maxillary artery after sagittal osteotomy during orthognathic is reported. After three bleeding episodes, a pseudoaneurysm was diagnosed with a computed tomography angiogram (CTA) and treated with an embolization of the internal maxillary artery with polyvinyl alcohol (PVA) successfully.

Accessory submaxillary gland: Two new case reports and a literature review.

Background: The accessory submaxillary gland is a very uncommon anatomical variant, and incidence in the general population has not yet been quantified. The presence of pathology in these glands is rarer still, thus often going unnoticed.

Material And Methods: We describe two accessory submaxillary gland cases, one asymptomatic and the other with chronic sialadenitis in the main and accessory gland caused by sialolithiasis.

Caliber-persistent Artery: A Case Report.

Unlabelled: The caliber-persistent labial artery (CPLA) is a vascular anomaly in which a main branch of the artery penetrates the submucosal area of the lip without loss of caliber. It commonly presents as an elevated soft tissue mass and is often pulsatile on manual palpation. Clinical suspicion is important, given the risk of bleeding, either from slight trauma or accidentally if lack of awareness leads to excision of the lesion owing to an incorrect diagnosis.

Transoral (transvestibular-paramandibular) endoscopic approach for benign tumours in the infratemporal fossa.

We describe a minimally invasive transoral approach to the infratemporal fossa, by means of endoscopy, which facilitates examination and resection of lesions in this area. Furthermore, we outline the technique employed and a case treated with this approach, which permits a rapid access with very low patient morbidity, due to the use of endoscopy and of transoral access, instead of traditional transfacial approaches.

Platelet-Rich Plasma: A Study of the Variables that May Influence Its Effect on Bone Regeneration.

Background: Currently, the use of platelet-rich plasma in bone regeneration is a real option, although more than one opinion has alerted us to the absence of clinical benefits.

Purpose: Analysis of the factors able to modify the characteristics of the platelet preparation obtained by Curasan, Plasma Rich in Growth Factors (PRGF), Platelet Concentrate Collection System (PCCS) and SmartPrep systems, relating them to the type of clinical application and the final bone regeneration achieved.

Materials And Methods: A search was conducted in PubMed using the keywords "platelet-rich plasma," "PRP," "platelet rich growth factors," and "oral bone regeneration.

Autologous fat transfer to the cranio-maxillofacial region: updates and controversies.

Background: Autologous fat grafts have gained popularity among Cranio-Maxillofacial surgeons within the past years. Most publications report favourable outcomes but lack quantifiable evidence of graft survival.

Objectives: To assess autologous fat transfer for facial asymmetry, and review the literature focusing on current indications, techniques, complications, fat survival and patient satisfaction.

Bilateral synovial chondromatosis of the temporomandibular joint.

Purpose: To report an exceptional case of bilateral synovial chondromatosis (SC) of the temporomandibular joint (TMJ) and discuss diagnostic approaches, treatment options and follow-up data.

Patients And Methods: A 38-year-old woman presented with left preauricular swelling. Initial imaging studies revealed TMJ effusion only.

The meridian incision: a technical modification in the conservative surgery of the impacted maxillary canine.

We describe a technical modification of the apical repositioning flap in the conservative surgical treatment of the impacted canine in buccal position. This amendment improves the tooth's eventual visualization, thus permitting a better evolutive follow-up of its eruption process and, most importantly, providing the tooth with buccal attached gingiva that will accompany it in its downward progression, procuring a cervical contour without retraction, a satisfactory esthetic outcome and a physiologically correct periodontal ridge. The traditional apical repositioning flap also bestows the canine with attached gingiva; however, since the flap is sutured apically and its width is significantly smaller than the remaining surgical defect, the wound's closure is compromised at one of its edges and often requires healing by second intention at an undesired location next to the buccal sulcus.

Primary mandibular bone xanthoma. A case report.

We describe a case of a xanthoma located in the mandible of an 11-year-old boy. The lesion, apparently benign, did not produce pain. It did, however, produce mandibular expansion by infiltration.
