Introduction: The aim of this work was to analyze the occurrence and type of neoplasm in unilateral pathological lesions within the nose and paranasal sinuses in patients who underwent endoscopic surgery, in own material.
Material And Methods: Between 2006 and 2012 2295 patients, including 1006 women aged 15-84 and 1289 men aged 17-87, were operated on due to diseases of paranasal sinuses in the Department of Otolaryngology and Laryngological Oncology. The patients underwent surgery after a medical interview, physical examination, 3D CT of paranasal sinuses and laboratory tests. The removed lesions were histopathologically investigated. The studied group included the patients with only unilateral lesions and histopathologically recognized neoplastic lesion.
Results: In the studied material, neoplastic lesions occurred in 9.8% cases, out of which 5.4% were inverted papillomas, 3.1% osteomas, and 1.5% malignant tumors. However, in the patients who were operated due to hypertrophic changes within paranasal sinuses, neoplasm was found in 1.3% cases, while inverted papilloma in 0.7%, osteoma in 0.4% and malignant tumors in 0.1%, which altogether amounts to 8 times higher occurrence of neoplastic lesions in unilateral changes.
Results: Unilateral changes within paranasal sinuses require highly inquisitive pre-operative diagnostics, peri-operative analysis and histopathological evaluation.

The aim was to measure sphenoid sinus volume on the basis of computed tomography data post processing and to investigate the possible relationship with age, gender and mastoid pneumatization. Sphenoid sinus volume was measured using the semi-automatic post processing algorithm of MSCT DICOM datasets of 66 patients. There were 35 female and 31 male subjects.

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.

State Key Laboratory of Oral Diseases & National Center for Stomatology & National Clinical Research Center for Oral Diseases, West China Hospital of Stomatology, Sichuan University, Chengdu, Sichuan, 610041, China.
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.
