Endoscopically assisted removal of ectopic teeth in the floor of the orbit. Case report and latest literature review.

Ectopic sinonasal third molar is a rare condition characterized by the aberrant position of the third molar in the maxillar sinus. The etiology of the teeth in the maxillary sinus is commonly associated to trauma and iatrogenic dental procedures. We present the clinical case of a 33-year-old man who presents an ectopic tooth in the right maxillary sinus, located in the orbital floor, who requires endoscopic control through a maxillary approach when performing the extraction.

Submental Flap Versus Radial Forearm Free Flap for the Reconstruction of Medium Size Soft Tissue Defect in the Oral Cavity.

The aim of this work is to compare the functional and esthetic outcome of the submental flap and radial forearm free flap for the reconstruction of medium-sized soft tissue defect in the oral cavity. Patients diagnosed with squamous cell carcinoma of the oral cavity and reconstructed with a submental flap or radial forearm free flap between 2015 and 2020 were reviewed and analyzed. Tumor site, complication at the donor site, complication at the recipient site, duration of the hospital stay, local or cervical recurrence, and esthetic results were also analyzed to compare the difference in outcomes between the two groups.

An exchange technique in temporomandibular joint (TMJ) arthroscopy to insert a larger operative cannula to facilitate advanced procedures.

The paper describes a modification of the surgical technique for temporomandibular joint arthroscopy, using an exchange guide to replace the 2.2 mm cannula with one of 2.9 mm to better facilitate osteoplasty of the medial wall.

Tips and Tricks to Avoid Complications With Scapula Tip-Free Flap.

Purpose: Create a practical step-by-step guide to harvesting this flap, highlighting the critical points that can create problems during surgery and the postoperative period.

Methods: The tips and tricks to harvesting the scapula tip-free flap are described in different points, describing the patient preparation and skin incision, identification of the anterior border of the latissimus dorsi, dissection of the pedicle, bone osteotomy, flap inset, and closure.

Results: As the scapula tip-free flap provides skin, muscle, and bone tissue, it is a valid option for the reconstruction of the defects maxillary and mandibular region for facial reconstruction.

Innovative histological and histochemical characterization of tongue biopsies from patients with burning mouth syndrome.

Objectives: The present pilot study aims to perform an innovative histological and histochemical characterization of samples from patients with burning mouth syndrome (BMS) to correlate these findings with the clinical scenario.

Methods: To carry out this objective, the study samples were stained with the hematoxylin-eosin stain and later, an histochemical study was carried out to determine the composition of the extracellular matrix (ECM) using the stains of Alcian Blue, Picrosirius, Reticulin from Gomori and Verhoeff.

Results: The results of this study revealed histological patterns compatible with cellular hypertrophy in different layers of the epithelium as well as a greater keratinization in BMS cases.
