ObjectiveTo discuss clinical significance of total endoscopic thyroidectomy (TET) via chest-breast approach. MethodsThe clinical data of 890 patients with thyroid diseases from September 2008 to September 2015 in this hospital were analyzed retrospectively. These patients were divided into TET group (received TET, n=420) and traditional group (received traditional thyroidectomy, n=470). The data of operation and postoperative recovery were compared between these two groups. ResultsThere was no significant difference between the TET group and the traditional group in the operation time [(73.571 4±28.533 9) min versus (70.212 8±27.199 8) min, t=1.80, P=0.072 7], bleeding volume [(30.714 3±14.225 1) mL versus (29.106 4±13.559 1) mL, t=1.73, P=0.084 8], postoperative drainage [(60.000 0±27.287 9) mL versus (56.595 7±27.803 5) mL, t=1.84, P=0.066 2], postoperative hospitalization time [(5.333 3±1.085 1) d versus (5.446 8± 1.089 0) d, t=1.55, P=0.120 4], postoperative 24 h pain score [(5.333 3±2.308 7) points versus (5.404 3±2.182 1) points, t=0.47, P=0.637 8] and postoperative injury rate of recurrent laryngeal nerve [0.714 2% (3/420) versus 0.851 1% (4/470), x2=0.053 2, P=0.817 6] and hypoparathyroidism rate [0.476 2% (2/420) versus 0.851 1% (4/470), x2=0.465 5, P=0.495 1]. The score of aesthetic effect of incision on day 7 after operation in the TET group was significantly higher than that in the traditional group [(7.809 5±1.296 9) points versus (3.361 7±1.391 8) points, t=49.14, P < 0.000 1]. ConclusionTET is safe and effective, and could improve cosmetic effect for patients with thyroid diseases.
ObjectiveTo compare the effect of robotic thyroidectomy and endoscopic thyroidectomy on the voice function. MethodsThe clinical data of 181 patients with differentiated thyroid cancer admitted to Panzhihua Central Hospital of Sichuan Province from March 2022 to June 2023 were analyzed retrospectively. According to the operative mode, this patients were divided into two groups: the endoscope group (n=91) and the robot group (n=90). The subjective and objective acoustic indicators were compared between the two groups at 1 day before operation and 1 week, 1 month and 3 months after operation. ResultsThere were no significant difference in voice handicap index (VHI)-10 scores between the two groups at different time points before and after operation (P>0.05). There were no significant difference of VHI-10 scores between preoperative and different postoperative phases in the robot group (P>0.05). The score of VHI-10 at different postoperative phases in the endoscopic group was higher than that at 1 d before operation (P<0.05). The incidence of voice dysfunction (VHI-10 score ≥8) was 1.1% (1/90), 1.1% (1/90) and 0.0% (0/90) in the robot group, 1.1% (1/91) , 2.2% (2/91) and 0.0% (0/91) in the endoscope group at 1 week, 1 month and 3 months after operation respectively, there were no significant difference between the two groups (P>0.05). The fundamental frequency of patients in the endoscopic group was lower than that at 1 d before operation (P<0.05), and there was no significant difference between each phase after operation and at 1 d before operation of fundamental frequency in the robot group (P>0.05). The fundamental frequency of patients in the endoscopic group was lower than that in the robot group at 1 week after operation (P<0.05). The maximum phonation time of each phase after operation in the robot group was not significantly different from that at 1 d before operation (P>0.05). The maximum phonation time of 1 week after operation in the endoscopic group was shorter than that at 1 d before operation (P<0.05) and also shorter than that in the robot group (P<0.05). There were no significant difference in fundamental frequency perturbation, amplitude perturbation, harmonic noise ratio and voice disorder severity index between the two groups at different phases before and after operation (P>0.05). ConclusionCompared with endoscopic thyroidectomy, the voice function of robotic thyroidectomy via bilateral axillary breast approach is better.
ObjectiveTo summarize the research status of mandibular sensory dysfunction after transoral endoscopic thyroidectomy vestibular approach (TOETVA), and explore its potential treatment methods and existing problems, and provide ideas and methods for future clinical treatments or research. MethodThe domestic and foreign literatures about peripheral nerve injury and its treatment after TOETVA were searched and reviewed. ResultsMental nerve injury was considered to be the main cause of mandibular sensory dysfunction after TOETVA. Due to the lack of unified definitions and assessment standards, the true incidence remained unclear. In order to reduce the risk of mental nerve injury, methods such as exposing the mental nerve and combining vestibular approaches during surgery had certain advantages. In terms of treatment, several methods promoting nerve repair were noteworthy, including B vitamins, nerve growth factors, physical therapy and so on. In addition, some auxiliary treatments of Traditional Chinese Medicine also showed effectiveness in promoting nerve regeneration. ConclusionsIt is essential to avoid damage to the mental nerve and mandibular tissues during surgery. For patients with significant complaints postoperatively, active treatment should be pursued. Establishing objective and quantifiable standards for evaluating mandibular sensory dysfunction and seeking effective clinical plans through a multidisciplinary approach may be the direction for future research.
