Temporomandibular joint arthrocentesis guided by ultrasonography: An anatomical study
The temporomandibular joint (TMJ) arthrocentesis is a common procedure in maxillofacial surgery departments for the treatment of TMJ dysfunction. The use of ultrasonography in this area is rare, and in the vast majority of cases only as a diagnostic, and non-therapeutic use. Through this study we propose the equipment and ultrasound parameters necessary to obtain detailed and practical images when using ultrasonography as a therapeutic guide in arthrocentesis of TMJ. In addition, we provide data regarding the placement and working angulations of both the ultrasound probe and the needle that are ideal for facilitating image-guided puncture. It is a simple technique, with a relatively short l…
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. Although our diagnosis was by computerized tomography, magnetic resonance sialography is helpful to understand and describe this entity with greater precision. Results The first case report is an incidental finding and no intervention was required. However, case report num…
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.” Four widely accepted protocols for the ob…
Temporomandibular chronic dislocation : the long-standing condition
Background The temporomandibular joint (TMJ) dislocation can be categorised into three groups: acute, habitual or recurrent and long-standing. The long-standing or protracted lower jaw dislocation refers to a condition that persists for more than one month without reduction. There are a great variety of methods for its treatment, from the manual or non-surgical, to surgical ones like the indirect approach (conservative surgical approach) and direct approach (open joint). Additional procedures in unsuccessful cases may include extra-articular orthognathic techniques to correct a malocclusion until joint replacement. Material and Methods We report four new cases with a minimum of 6 weeks disl…
Caliber-persistent Artery: A Case Report
ABSTRACT 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. CPLA should be considered in the differential diagnosis of any lesion affecting the lip, especially to differentiate from mucocele or squamous cell carcinoma. This particular case of CPLA in the upper lip of a girl presents a both unu…
