RESULTS
A total of 159 patients (70 men and 89 women) were treated in our
hospital and consisted of TVFP with 66 cases and MLS 93 cases . All
cases were retrospectively reviewed at a mean follow-up of 6 months. Age
range of cases was 24 – 75 years was mean 51.9 ± 11.6 years. Our study
found no significant differences in sex, age, disease course,
preoperative GRB and VLS(Table 1 and
Table S1).
All the surgical operations were completed successfully. For the TVFP
treatment group, the polyps were removed within 2 -10 minutes. 2
patients were cured after twice operations. There were 12 patients (5
cases with severe cardiovascular disease, 4 cases with cervical spine
disease, and 3 cases with obese oropharyngeal cavity stenosis and high
laryngeal body) underwent TVFP treatment instead of MLS treatment.
The surgical outcomes were evaluated one month after the operation, the
postoperative GRB and VLS were significantly improved (p <
0.001)(Table S2). Among the patients with edematous, gelatinous and
vascular polyps, the postoperative outcomes were satisfactory for both
TVPF and MLS treatment groups (p = 0.853 versus p = 0.786). The efficacy
of TVFP was slightly worse than MLS in the fibrous type of polyps group
(p = 0.009 versus p = 0.019) (Table 2).
The patients in the TVFP treatment group had no surgical complications,
whereas 7 patients in the MLS treatment group had loose and worn upper
incisors, 9 patients had bruising and pain in the soft palate and
lateral oropharyngeal wall, 5 patients had laceration in the lateral
oropharyngeal wall, and 3 patients had numbness in the tongue. However,
all patients recovered after symptomatic treatment without leaving
permanent damage (Table 3).
