Results
The study included 40 patients (90% males),
mean age 60.1 ± 7.3 years,
range 49–70 years.
In 28 patients (70%) the tumor was glottic an in 12 patients (30%) supraglottic.
All patients had hoarseness,
20 (50%) were coughing,
30 (75%) experienced swallowing problems,
and 22 patients (55%) complained of neck pain.
Infiltration of the paraglottic spaces was seen in 24 (60%) patients on MRI and in 16 (40%) patients at the surgery,
which was statistically significant difference (z = −0.4; p < 0.05),
with sensitivity of 78% and specificity 65%.
(Fig. 1).
Preepiglottic space was invaded by tumor in 9 (23%) patients on MRI and in 8 (20%) patients at the surgery,
which has not been shown to be of statistically significance difference (z = −0.4; p > 0.05) (Fig.
2).
Sensitivity for infiltration of preepiglottic space is 90% and specificity 80% (Figure 3).
In all the patients squamocellular carcinoma was confirmed on preoperative biopsy.
Using TNM classification [2],
based on pathohistological analysis of the surgical specimen,
on MRI 26 (65%) patients were classified as T3,
14 (35%) patients as T2,
while on pathohystological specimens after surgery,
19 patients were classified as T3 (48%) and 21 as T2 (52%)
