title: Clinical value of office-based endoscopic incisional biopsy in diagnosis of nasal cavity masses.
abstract: OBJECTIVE
  To evaluate clinical features and the diagnostic accuracy of office-based endoscopic incisional biopsy in patients with nasal cavity masses.
  
  
  METHODS
  Diagnostic test assessment with chart review.
  
  
  METHODS
  Tertiary referral center.
  
  
  METHODS
  From January 1997 to August 2006, preoperative diagnosis was achieved using endoscopic incisional biopsy in 521 patients. Cytopathologic and histologic findings were categorized as malignancy, benign neoplasm, or non-neoplastic lesion. Preoperative imaging was done in 462 patients (computed tomography: 438 cases; magnetic resonance imaging: 24 cases). We investigated the accuracy of endoscopic incisional biopsy and preoperative imaging by comparing it with pathologic results from tumor resection as the "gold standard."
  
  
  RESULTS
  Most of the patients had unilateral nasal symptoms (e.g., nasal obstruction, unilateral epistaxis, unilateral facial pain), and the clinical symptoms were of little diagnostic value in the differentiation of tumor and inflammatory lesion. The sensitivity and specificity of endoscopic incisional biopsy were 43.7 and 98.9 percent, respectively, for the diagnosis of nasal cavity malignancies, and 78.2 and 96.2 percent, respectively, for the diagnosis of benign neoplasms. The sensitivity and specificity of preoperative imaging were 78.3 and 97.5 percent, respectively, for the diagnosis of nasal cavity malignancies and 66.4 and 86.3 percent, respectively, for the diagnosis of benign neoplasms. Combining the two modalities increased diagnostic accuracy in nasal cavity masses.
  
  
  CONCLUSIONS
  Endoscopic incisional biopsy alone did not ensure accurate diagnosis of nasal cavity tumors, but in combination with preoperative imaging it was helpful for the diagnosis of nasal cavity malignancies.
