만성 부비동염 환자에서 폐색을 유발한 함기화된 구상돌기 1예

Pneumatization is common variant of the paranasal structures, especially on intranasal turbinate. Pnematized uncinate process is very rare condition and can cause nasal obstruction with underlying nasal pathology. A 11-year-old man presented with nasal obstruction. Computed tomography confirmed chronic pansinusitis with polyposis and identified left peumatization on uncinate process. The pnematized uncinate process was removed endoscopically during functional endoscopic sinus surgery. In any case of paranasal sinus pathology, anatomy should be carefully reviewed prior to performing endoscopic sinus surgery in terms of both pathologies and anatomical variants such as pneumatized uncinate process.
