Practical management recommendations for incidental otolaryngologic findings on cone beam computed tomography.

Cone beam computed tomography (CBCT) frequently captures unexpected structural abnormalities unrelated to the original intent of the diagnostic test. Once identified by dentists, these findings often require appropriate clinical referral for further investigation. This study reviewed recent literature using a comprehensive search to identify and curate common CBCT incidental findings (IFs).

Adenoidal-Nasopharyngeal Ratio in Healthy Adults on Cone Beam Computed Tomography.

Objective: This study aimed to quantify the adenoidal-nasopharyngeal ratio (ANR) in a cohort of healthy adults on cone beam computed tomography (CT) using the Fujioka method, which is a reproducible measure of adenoid size and nasopharyngeal patency.

Methods: Electronic health records and maxillofacial cone beam CT in 202 consecutive patients aged 16 years and older were retrospectively reviewed. Patients with a history of adenoidectomy, sinonasal disease, lymphoproliferative disorders, and cleft palate were excluded from the study.

Targeting the endothelin axis as a therapeutic strategy for oral cancer metastasis and pain.

Metastasis reduces survival in oral cancer patients and pain is their greatest complaint. We have shown previously that oral cancer metastasis and pain are controlled by the endothelin axis, which is a pathway comprised of the endothelin A and B receptors (ETR and ETR). In this study we focus on individual genes of the pathway, demonstrating that the endothelin axis genes are methylated and dysregulated in cancer tissue.

A radiographic study of permanent molar development in wild Virunga mountain gorillas of known chronological age from Rwanda.

Objectives: While dental development is important to life history investigations, data from wild known-aged great apes are scarce. We report on the first radiographic examination of dental development in wild Virunga mountain gorillas, using known-age skeletal samples recovered in Rwanda.

Materials And Methods: In 43 individuals (0.

Radiographic Evaluation of Maxillary Sinus Lateral Wall and Posterior Superior Alveolar Artery Anatomy: A Cone-Beam Computed Tomographic Study.

Objective: The purpose of the current study is to assess the thickness of the maxillary sinus lateral wall in dentate and edentulous patients using cone beam computed tomography (CBCT). This study also provides information about the diameter, prevalence, and course of the posterior superior alveolar artery (PSAA), and its relation to the maxillary sinus floor.

Materials And Methods: Four hundred and thirty CBCT scans of the maxillofacial complex (860 maxillary sinuses) were reviewed.

Mandibular changes on panoramic imaging after head and neck radiotherapy.

Objectives: Changes to the radiographic appearance of the jaws after head and neck radiotherapy have not been thoroughly characterized. This retrospective study examines changes to the appearance of the mandible on panoramic images following intensity-modulated radiotherapy (IMRT) and relates these changes to medical co-morbidities and radiation dose.

Study Design: The medical and dental charts, and panoramic images of 126 patients who received IMRT at the Princess Margaret Hospital between January 1, 2005, and December 31, 2008, were analyzed independently by three observers.

Does Fluorodeoxyglucose Positron Emission Tomography With Computed Tomography Facilitate Treatment of Medication-Related Osteonecrosis of the Jaw?

Purpose: There is considerable controversy over the treatment of medication-related osteonecrosis of the jaw (MRONJ) and growing interest and debate related to the timing, type, technique, and goals of surgical intervention. The specific aim was to evaluate the predictive value of fluorodeoxyglucose (FDG) positron emission tomography (PET) with computed tomography (CT) on healing outcomes in patients undergoing surgery for MRONJ of the mandible.

Materials And Methods: A retrospective cohort study of 31 patients with 33 MRONJ lesions of the mandible who had undergone surgery using FDG PET-CT was conducted.

Salivary duct carcinoma ex pleomorphic adenoma of the palate: a case report.

Carcinoma ex pleomorphic adenoma is a rare malignancy of the head and neck, particularly in the minor salivary glands. Most cases arise in the major salivary glands, most commonly in the parotid gland, followed by the submandibular gland. The malignant component of the tumor varies, but can be salivary duct carcinoma, adenoid cystic carcinoma, mucoepidermoid carcinoma, squamous cell carcinoma, or adenocarcinoma, not otherwise specified.

Fluorodeoxyglucose positron emission tomography with computed tomography detects greater metabolic changes that are not represented by plain radiography for patients with osteonecrosis of the jaw.

Purpose: Imaging is important to identify subclinical changes and for treatment planning in patients with osteonecrosis of the jaw (ONJ) exposed to antiresorptive therapy. The aim of this study was to compare the findings at radiography with those at fluorodeoxyglucose (FDG) positron emission tomography (PET) with computed tomography (CT) for patients with ONJ related to antiresorptive therapy.

Materials And Methods: A cross-sectional retrospective analysis of patients with clinically identified ONJ lesions of the mandible was performed.

Labial salivary gland involvement in neonatal hemochromatosis: a report of 2 cases and review of literature.

Neonatal hemochromatosis (NH) is a severe disease of fetal or perinatal onset, in which iron deposition occurs within hepatic and extrahepatic sites without involving the reticuloendothelial system. Labial minor salivary gland biopsy has been suggested as a diagnostic adjunct in patients suspected of having NH, as hemosiderin accumulates in acinar epithelial cells. Prior to this salivary gland pathology, a diagnosis of NH was often delayed, rendered only after the usual causes of neonatal liver failure had been excluded.
