Objectives:
Careful assessment of tumor extension is required before partial laryngectomy in order to ensure optimal carcinological safety. Laryngoscopy and CT-scan constitute the explorations of reference. We investigated the value of these two examinations and their association for the evaluation of glottic and supraglottic tumors.
Method:
We compared laryngoscopy and CT findings with those of the pathologic examination of the surgical specimen in a retrospective study of 57 patients.
Results:
The results were presented by T-staging, then as a function of the laryngeal floor of the tumor and the anatomic localization. The laryngoscopy findings were most contributive for small tumors. Large spaces are better examined with the scanner.
Conclusion:
This study showed that the performance of laryngoscopy and CT-scan for the assessment of glottic and supraglottic tumors can be improved by a better knowledge of the limitations of each type of explorations for this type of assessment. CT-scan currently provides a better topographic assessment of the tumor than endoscopy; even higher performance can be expected with the advent of technological advances.
