Material and Method: In this study, 251 patients’ nasal cavities and paranasal sinuses were evaluated using CBCT (Newtom 5G, Verona Italy) images in terms of anatomical variations. The high-resolution (voxel and slice thickness: 0.2 mm) multiplanar reformatting images (MPR) were used for the evaluation of the variations. Results: The most common anatomical variation of nasal cavity and paranasa...

A unilateral tumour in the nasal cavity or paranasal sinuses is commonly caused by polyps, cysts, and mucoceles, as well as invasive tumours such as papillomas and squamous cell carcinomas. Schwannomas, in contrast, are rare lesions in this area (Minhas et al., 2013). We present a case of a 52-year-old female who presented with a 4-year progressive history of mucous hypersecretion, nasal obstru...

Malignant peripheral nerve sheath tumors of the nose and paranasal sinuses are extremely uncommon. We report the case of a 65-year-old woman who presented with a rapid emergence of "nasal polyps" that completely obstructed her nasal passages. Six years earlier she had been assessed elsewhere for nasal polyps. At presentation, the patient exhibited gross polyposis, with lesions protruding from b...

Allergic mucin is described as thick, peanut butter-like mucus impacted in the paranasal sinuses of patients with allergic fungal rhinosinusitis. The presence of allergic mucin in the middle ear has never been reported. We encountered a 65-year-old female with allergic mucin found impacted in her left middle ear and mastoid cavity during revised tympanoplasty surgery at our institute. Bilateral...

Rhinocerebral mycosis is an invasive fungal infection which occurs primarily in the paranasal sinuses and progresses to involve the brain and/or the orbit. It is commonly seen in immunocompromised individuals and can be most effectively treated if diagnosed early, when it is limited to the nasal cavity and the paranasal sinuses. Even though it is acceptable that surgical debridement in combinat...

Particle beam therapy has been rapidly developed in these several decades. Proton and carbon ion beams are most frequently used in particle beam therapy. Proton and carbon ion beam radiotherapy have physical and biological advantage to the conventional photon radiotherapy. Cancers of the skull base, nasal cavity, and paranasal sinus are rare; however these diseases can receive the benefits of p...
