Abstract :

BACKGROUND

Staging of primary carcinoma of the larynx play an important role in surgical management of the disease .This staging depends on the clinical finding and radiological examination, supported by pathological assessment of the excised tumor.

METHOD

A total of 20 patients were studied retrospectively. Preoperative staging protocol included indirect laryngoscopy, direct microlaryngoscopy and contrast enhanced CT scan. The histologic findings were compared with the clinical findings and the CT scan MR images. The impact of each diagnostic method on pretherapeutic staging was analyzed.

RESULTS

The CT staging of laryngeal carcinoma showed very high accuracy in staging subglottic and supraglottic tumours (100%), (77.7%) respectively in comparison to clinical staging and lower accuracy (66.66%) in staging glottic tumours. Underestimation of all tumours was 15% of cases (especially small and superficial lesions).

CONCLUSION

The accuracy of clinical staging decreased from glottic to supraglottic to subglottic tumours. Conversely, the staging accuracy of sectional imaging is best in subglottic tumours and supraglottic tumours and lower in glottic tumours.
