Aggressive juvenile fibromatosis of the paranasal sinuses: case report and brief review

open access: yesJournal of Hematology & Oncology, 2008
Desmoid fibromatoses are benign, slow growing fibroblastic neoplasms, arising from musculoaponeurotic stromal elements. Desmoids are characterized by local invasion, with a high rate of local recurrence and a tendency to destroy adjacent structures and ...

Supervised Contrastive Learning to Classify Paranasal Anomalies in the Maxillary Sinus [PDF]

open access: yesarXiv, 2022
Using deep learning techniques, anomalies in the paranasal sinus system can be detected automatically in MRI images and can be further analyzed and classified based on their volume, shape and other parameters like local contrast. However due to limited training data, traditional supervised learning methods often fail to generalize.

Nasopharyngeal Melanoma [PDF]

open access: yes, 2018
Mucosal nasopharyngeal melanoma is a rare head and neck melanoma. Prognosis is poor (5-year overall survival rate of 10–30%) with high rates of metastases and local recurrence. Head and neck mucosal melanoma represents 0.8–3.7% of all melanomas and 0.03%

Imaging in Sinonasal Disorders [PDF]

open access: yes, 2020
Computed tomography (CT) is the “working horse” in sinonasal imaging and should always be the first choice. Magnetic resonance imaging (MRI) is complementary to CT when complications to rhinosinusitis or neoplasm are suspected.

Malignant Versus Benign Tumors of the Sinonasal Cavity: A Case-Control Study on Occupational Etiology [PDF]

open access: yes, 2018
Case-control studies on malignant sinonasal tumors and occupational risk factors are generally weakened by non-occupational confounders and the selection of suitable controls. This study aimed to confirm the association between sinonasal malignant tumors

Unsupervised Anomaly Detection of Paranasal Anomalies in the Maxillary Sinus [PDF]

open access: yesarXiv, 2022
Deep learning (DL) algorithms can be used to automate paranasal anomaly detection from Magnetic Resonance Imaging (MRI). However, previous works relied on supervised learning techniques to distinguish between normal and abnormal samples. This method limits the type of anomalies that can be classified as the anomalies need to be present in the training ...

Histo-Morphological Spectrum of Paranasal Sinus TumoursA Three Year Study

open access: yesAnnals of Pathology and Laboratory Medicine, 2018
Background: Maxillary, Ethmoid, Sphenoid and Frontal sinuses constitute the paranasal sinuses. Paranasal sinus tumours are highly diverse and uncommon tumours of all head and neck neoplasms.

Trans-nasal endoscopic and intra-oral combined approach for odontogenic cysts [PDF]

open access: yes, 2018
Maxillary cysts are a common finding in maxillofacial surgery, dentistry and otolaryngology. Treatment is surgical; a traditional approach includes Caldwell-Luc and other intra-oral approaches.
