Clinical Manifestations and Surgical Treatment Outcomes of Paranasal Sinus Osteoma

  • 1Department of Otorhinolaryngology Haed & Neck Suregery, Yonsei University College of Medicine, Seoul, Republic of Korea


Background and Objectives
Osteomas are the most common benign tumors of the nasal cavity and paranasal sinuses (PNSs). In this study, clinical features and imaging findings were analyzed in patients with osteoma confirmed by ostiomeatal unit (OMU) computed tomography (CT) and PNS CT, and the surgical treatment performed at our hospital was introduced.
The Severance Clinical Research Analysis Portal (SCRAP) service of Severance Hospital was used to collect research data. A total of 128 cases of osteomas of the nasal cavity or PNSs confirmed by OMU CT or PNS CT was retrospectively reviewed, including the location and size of the osteoma, clinical features, accompanying findings on imaging tests, and cases of surgical treatment.
In this study, osteomas were found in about 0.55% of patients who underwent computed tomography. Osteomas were most frequently found in the ethmoid sinus, followed by the frontal sinus, fronto-ethmoid sinus, maxillary sinus, intranasal sphenoid sinus, and maxillary sinus-ethmoid sinus. Patients with osteomas complained of symptoms such as rhinorrhea, postnasal drip, nasal congestion, hyposmia, headache, visual disturbance, and lacrimal duct obstruction.
Surgical treatment was considered for patients presenting with severe headache, visual field symptoms, or accompanying rhinosinusitis. Surgery was performed by endoscopic or external approaches depending on location and size of the osteoma.

  • Fig. 1. CT scan of the 42-year-old male patient. A-C: Pre-operative CT scan. An osteoma filling the right frontal sinus and posterior ethmoid sinus was discovered. D-F: Post-operative CT scan at 15 months follow-up. A, D, E: Coronal view. B, C, F: Axial view. CT, computed tomography

  • Fig. 2. CT scan of 25-year-old female patient. A-C: Pre-operative CT scan. An osteoma of 2.48×4.18×3.22 cm in size was compressing the optic nerve and forming a sphenoid sinus mucocele. D-F: Post-operative CT scan at 13 months follow-up. A, B, D, E: Coronal view. C, F: Axial view. CT, computed tomography.

  • Fig. 3. CT scan of a 47-year-old female patient who visited outpatient clinic due to incidental finding of osteoma. An osteoma about 2 cm in size of posterior maxillary sinus was noted. A: Coronal view. B: Axial view. CT, computed tomography
