Foreign Body in the Sphenoid Sinus

Philippine Journal of Otolaryngology Head and Neck Surgery, 2014
Dear Editor, Foreign bodies in the paranasal sinuses are not so common, but are still possible.  The structures most often involved are maxillary and the frontal sinuses.1 In our case, the sphenoid sinus, which is posterior and deep, was involved ...

A case of foreign bodies self-inserted into the paranasal sinus via an oroantral fistula

SAGE Open Medical Case Reports, 2020
Foreign bodies in the nasal cavity are rarely seen in adults, and most cases are traumatic in origin. Multiple foreign bodies in adults are particularly rare. Foreign bodies induce pain, bleeding, and infection but are easily removed in most cases.

Glass Particles in the Nasal Cavity for 30 Years and Squamous Cell Carcinoma: Is There a Relationship? [PDF]

, 2022
Nasal cavity tumors constitute a very small part of head and neck malignancies. Although paranasal sinus tumors due to the presence of backward foreign bodies, neoplasms of nasal cavity associated with a foreign body are extremely rare.
