Results
Thirty-two patients (30 males, 2 females) who had undergone
robotic tongue base resection and uvulopharyngoplasty were
included in this study. The mean age of the patients was 43.2
+ 10.7. Patients included in the study had an average body
weight measurement of 94.1 + 12.6 kg, with body weight
measurements ranging from 78 to 125 kg. The mean BMI
value of the patients was 31.4 + 4.7. There was a statistically
significant difference between preoperative body weight measurements and third-/sixth-postoperative-month body weight
measurements (P < .05). However, there was no statistically
significant difference between third-postoperative month and
sixth-postoperative month body weight measurements (P >
.05; Table 1).
A statistically significant difference was found between the
preoperative BMI values and third-/sixth-postoperative month
BMI values of all patients in the study (P < .05). Once again,
there was no statistically significant difference between thirdand sixth-postoperative month BMI values (P ¼ .05; Table 1).
Preoperative respiratory function test parameters were compared with third- and sixth-postoperative month parameters.
The third- and sixth-postoperative month values were compared with the preoperative values of forced vital capacity
(FVC), forced expiratory volume 1 (FEV1), FEV1/FVC, peak
expiratory flow (PEF), and forced expiratory flow 25-75 (FEF
25-75). Statistically significant increases in these values have
been demonstrated (P < .05; Table 2).
When statistical results were evaluated, there was no
statistically significant correlation between preoperative/
third-postoperative month BMI change and preoperative/

Note. There was a statistically significant correlation between the preoperative/third postoperative month BMI change and the preoperative/third postoperative month PEF and FEF 25-75 change. Because PEF and FEF 25-75 values
give better information about large and medium airway obstruction.
