Adenoid cystic carcinoma (ACC) is a distinct salivary gland neoplasm that predominantly occurs in the minor salivary gland. ACC is an uncommon tumor that progress slowly affecting 5% of paranasal sinuses with high distant metastasis rate in advance stages. This salivary gland tumor is difficult to diagnose both clinically and histopathologically due to its indolent presentation and diverse histopathological patterns. Hence, immunohistochemistry plays a decisive role in diagnosing this tumor. A recurrent case of ACC of paranasal sinuses in the maxillary sinus of a 41-year-old female patient without any extraoral abnormality is reported.

Objective: The goal of this study was to better understand the epidemiology, clinical characteristics, and treatment outcomes of head and neck sarcomas using real-world data from Japan.
Methods: Using the Japanese Head and Neck Cancer Registry, we identified 438 patients who were pathologically diagnosed with head and neck sarcoma between 2011 and 2020. We compared epidemiological, clinical, and prognostic data for the different histological types of sarcoma.

Background: Craniofacial mucormycosis is a highly lethal infectious disease. This study aims to assess and analyze multiple variables, including clinical, socioeconomic, and biochemical markers, to identify and examine risk factors for mortality associated with this mycotic infection.
Material And Methods: A retrospective analysis was conducted on 38 patients who sought medical attention at the Otolaryngology and Head and Neck Surgery Division of a tertiary-level hospital in Monterrey, Mexico.

Objectives: To develop a platform including a deep convolutional neural network (DCNN) for automatic segmentation of the maxillary sinus (MS) and adjacent structures, and automatic algorithms for measuring 3-dimensional (3D) clinical parameters.
Materials And Methods: 175 CBCTs containing 242 MS were used as the training, validating and testing datasets at the ratio of 7:1:2. The datasets contained healthy MS and MS with mild (2-4 mm), moderate (4-10 mm) and severe (10- mm) mucosal thickening.

Chronic rhinosinusitis (CRS) is a common inflammatory disease of the paranasal sinuses with a yet unknown etiology. As studies continue to elucidate the disease's heterogeneity inflammatory profile and presentation, there is a growing interest in the influence of the nasal microbiome on disease pathogenesis and chronicity. The sinus microbiota appear dominated by the and genera; known upper airway pathogens, such as , are present in the upper airways of healthy individuals, though at relatively lower abundances than in CRS patients.

Alveolar rhabdomyosarcoma (aRMS) is a rare pediatric malignant tumor with a poor prognosis, particularly when located in the rhinopharynx and sphenoidal floor, which complicates diagnosis and increases the risk of misclassification as benign growths. The specific genotype of aRMS is associated with a worse clinical outcome. In young children, especially those aged 4 to 12 years, rhinopharyngeal masses are often attributed to chronic adenoiditis; however, other benign (e.
