Paranasal Schwannomas: A Comprehensive Study of 2 Cases.

ABSTRACT

Paranasal sinus tumors are a heterogeneous group of neoplasms (with paranasal schwannomas being a rare subtype) that are often present with non-specific symptoms, such as nasal obstruction and epistaxis. Thus, early diagnosis is crucial for optimal management. This study presents 2 cases of paranasal schwannomas, detailing their clinical presentation, diagnostic methods, and treatment approaches. Both patients underwent endoscopic sinus surgery with successful tumor excision and had no significant complications or recurrences during follow-up. Diagnosis was based on a combination of clinical examination, radiological imaging (computed tomography and magnetic resonance imaging), and histopathological confirmation with immunohistochemical staining. Treatment consisted primarily of endonasal resection, with consideration of frontal craniotomy if necessary. This study aims to contribute to the understanding of paranasal schwannomas and emphasizes the importance of early detection and treatment to improve patient outcomes.
