Transformation of a maxillary paranasal sinus fungal ball into a mass-like form of invasive fungal sinusitis in the immunocompromised host

Proceedings of Singapore Healthcare
Background Paranasal sinus fungal balls are typically non-invasive and can be managed conservatively in the immunocompetent. In the immunocompromised, life-threatening invasive transformation is possible. The temporal relationship between onset of fungal

Outcomes in Orbit‐Sparing Versus Orbit‐Sacrificing Surgery for Sinonasal Malignancies With Orbital Involvement: A Systematic Review and Meta‐Analysis

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Background Sinonasal malignancies with orbital involvement may be managed with orbit‐sacrificing or orbit‐preserving surgical approaches, with a recent shift towards orbital preservation to reduce postoperative morbidity while maintaining oncological success.

Obesity and Its Impact on Endoscopic Sinus Surgery Outcomes in Patients With Chronic Rhinosinusitis With Nasal Polyps

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Purpose The rising prevalence of obesity introduces challenges in surgical contexts, including endoscopic sinus surgery (ESS) for chronic rhinosinusitis with nasal polyps (CRSwNP). However, the impact of obesity on ESS outcomes remains underexplored. This study aims to evaluate the association between obesity and surgical complexity, operative

Diagnostic accuracy and influencing factors of preoperative biopsies in sinonasal malignancy

American Journal of Otolaryngology
Objectives: The nasal cavity's cytological diversity necessitates pathological confirmation for treatment planning, especially in malignancies. However, the accuracy of preoperative biopsies and their influencing factors are still unclear.

Periocular Myxoma in a Child

Case Reports in Ophthalmological Medicine, 2012
Myxomas are locally invasive, benign mesenchymal neoplasms with odontogenic, osteogenic, or soft tissue origin. Facial myxomas probably account for less than 0.5% of all paranasal sinus and nasal tumors.

Decreased Production of Tissue Plasminogen Activator in Endothelial Cells From Nasal Polyps

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Introduction Previous studies have demonstrated that chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by excessive fibrin deposition which is related to impaired production of tissue plasminogen activator(t‐PA) by epithelial cells.

Morphological Sinus Features and Chronic Rhinosinusitis Risk: A Radiomics Study

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objectives Anatomical factors of the sinuses significantly impact the progression of chronic rhinosinusitis (CRS). This study aims to investigate the correlation between morphological sinus features and the risk of CRS onset to provide evidence‐based support for clinical management.
