The article is devoted to the influence of pharyngolaryngeal reflux on the voice acoustic parameters in patients before and after the antireflux surgery (fundoplication). The study involved 12 patients aged 33 to 64 years with a confirmed impedance–pH monitoring diagnosis of gastroesophageal reflux disease. The control group included 10 patients aged 18 to 33 years. These subjects did not have any upper respiratory diseases (including pharyngolaryngeal reflux) and gastrointestinal tract diseases. Computer voice analysis was used to objectively evaluate the voice acoustic parameters. In patients before fundoplication, a statistically significant increase in Jitter and Shimmer parameters was observed in 100% of cases compared with the control group (p ≤ 0,05). In the late postoperative period, 6 months after surgery, the analysis of acoustic parameters of voice in the study group revealed: Jitter and Shimmer indicators in 100% of cases significantly decreased compared to the preoperative values (p ≤ 0,05), which indicates an improvement in voice function. Jitter and Shimmer were the most diagnostically significant parameters.

Proper Interpretation

Intraoperative neuromonitoring during thyroid surgery has been used to successfully prevent permanent neurological injury by early identification of anatomical variants. Proper interpretation of neuromonitoring data requires knowledge of what factors might affect the data. In this study, we examined the effect of surgical positioning on the latency and amplitude of neural recordings made from the vocalis muscle during thyroid surgery. A retrospective review was performed of 145 patients who underwent thyroid surgery. Eighty-three had open cervical procedures, and 62 had robotic-assisted transaxillary procedures. Intraoperative neuromonitoring recordings were made by stimulation of the vagus and recurrent laryngeal nerves for both groups. Ultrasound measurements were made of a subset of the transaxillary patients immediately before and after arm positioning. Groups differed only on right-sided recordings. Patients with transaxillary surgeries had significantly shorter latencies evoked from the vagus nerve. We found that vagus nerve–evoked latencies were also correlated to ultrasound measurements of the nerves. Surgical positioning during thyroid surgery is a factor that may affect intraoperative neuromonitoring data and should be taken into account by the surgeon during interpretation.

Laryngeal Nerve Injury

Background: Total thyroidectomy (TT) and completion thyroidectomy (CT) are two common surgical operations that are frequently followed by vocal symptoms despite preservation of the recurrent laryngeal nerve (RLN) and of the external branch of superior laryngeal nerve (EBSLN). The aim of this study was to analyze vocal alterations through endoscopic findings, videolaryngostroboscopy (VLS), acoustic vocal parameters and impact on patients’ quality of life after surgery in the absence of laryngeal nerve injury. Methods: We enrolled 198 patients who underwent thyroidectomy by the same surgeon. One hundred twenty-six patients underwent TT (group TT) while 72 underwent CT (group CT). All patients underwent preoperative VLS and Voice Handicap Index (VHI) assessment and postoperative VHI, VLS and Acoustic Voice Analysis with Multidimensional Voice Program Analysis 12 to 18 months after surgery. Results: We observed a statistically significant higher rate of EBSLN injury in CT compared to TT. Even in the absence of RLN and EBSLN injury, patients who underwent TT and CT presented slightly worse acoustic vocal parameters and VHI scores compared to healthy controls. Interestingly, some acoustic vocal parameters and VHI scores were significantly worse in group CT compared to group TT. Conclusions: The higher rate of EBSLN injury in CT rather than in TT suggests a higher surgical risk in CT. The vocal parameters of loudness and self-perception of voice were significantly worse after CT, suggesting a larger trauma in patients’ vocal outcome in CT if compared to TT, although these alterations were not reported as psychologically limiting daily life of patients. Nevertheless, the existence of multiple factors contributing to vocal alterations after thyroidectomy highlight the importance of a routine comprehensive functional voice analysis before and after surgery.

INTRODUCTION The aims of this study were to assess and compare vocal cord functions before and after thyroid surgery after intra-operative identification of recurrent laryngeal nerve. PATIENTS AND METHODS Recurrent laryngeal nerve (RLN) is seen intra-operatively in all cases undergoing thyroid surgeries. Vocal cord functions including any voice change were evaluated by indirect laryngoscopy (I/L) and direct laryngoscopy (D/L) before and after surgery. RESULTS Prospective study on 100 patients over 18 months with a total of 146 nerves at risk (NAR). Majority were women (n = 86) with mean age of 37.48 years (range, 13–60 years). RLN was seen in all patients and 19 patients complained of some change in quality of their voice after surgery. Evaluation by I/L and D/L at 6 weeks showed recurrent laryngeal nerve palsy (RLNP) in nine (47.36%) and five (26%) of these 19 patients respectively. Analysed according to total NAR, the incidence of voice change and temporary RLN palsy (I/L and D/L) at 6 weeks was still less at 13.01%, 6.16% and 3.42%, respectively. Voice change improved in all cases at 3 months with no RLNP palsy by I/L or D/L. All these 19 patients had undergone difficult or extensive surgery for malignancy, large gland, extratyhroidal spread or fibrosis. CONCLUSIONS Despite identification and preservation of RLN, patients can develop postoperative voice change and RLNP although all voice change cannot be attributed to damaged RLN. Proper assessment of vocal cord functions by I/L and D/L laryngoscopy is required to rule out injuries to these nerves. Risk of damage is higher in patients undergoing more difficult surgery.

Experienced thyroid surgeons are often able to identify the parathyroid glands, but sometimes it is difficult to differentiate them from other contiguous tissues. Contact endoscopy was introduced in otolaryngology for the characterization of normal and pathological epithelia. Our objective was to analyze contact endoscopy as an auxiliary method for identification of the parathyroid glands during thyroid surgery. Five total thyroidectomies and 5 hemithyroidectomies were performed in September 2001. After surgical exposure, contact endoscopy was performed. A total of 15 peritracheal regions were studied. Superior and inferior parathyroid tissues were identified on the basis of color, size, and probable location. Contact endoscopy was performed before and after use of methylene blue stain. Contact endoscopy was also used in neighboring areas. We compared the visual impression to the contact endoscopy findings. Two structures were visually supposed to be the superior and inferior parathyroid glands in each case. From 30 visually supposed glands, 25 were confirmed by telescope. Of the other 5 structures initially supposed to be parathyroid tissue, 3 were adipose tissue and 2 were thyroid parenchyma. In the 5 cases in which the identification of one of the glands was not confirmed, an additional contact examination enabled us to further identify parathyroid glands in 3 cases in which structures were initially identified as adipose tissue. Contact endoscopy is an efficient auxiliary method for the identification of the parathyroid glands during thyroid surgery that poses little risk of morbidity to the patient.

Abstract Background Neuromuscular blocking agent (NMB) dosage suggested in current intraoperative neural monitoring (IONM) clinical guideline might cause operational difficulty during thyroid surgery. This study evaluated the feasibility of sugammadex with an enhanced NMB recovery protocol. Methods Complete IONM data for 57 patients who had normal cord mobility were investigated: 32 patients received rocuronium 0.6 mg/kg at anesthesia induction and sugammadex 2 mg/kg at vagus nerve exposure (group S) and 25 received rocuronium 0.3mg/kg with 0.9% NaCl 2mL/kg instead (group R). Electromyography (EMG) signals were obtained from the vagus nerve and RLN before and after resection of the thyroid lobe and were defined as V1, V2 and R1, R2 signals, respectively. The train-of-four ratio (TOFr) was used for continuous quantitative monitoring of neuromuscular transmission. Results Mean EMG in Group S (vagus nerve: 722.728 ± 160.11μV, RLN: 1028.64 ± 180.34μV) was greater than Group R (568.884 ± 135.15, 776.66 ± 145.91μV) from first minute after administration of sugammadex (P <0.05). The time for tracheal intubation was 102.97±64.5 seconds in group S with high dose rocuronium, while 195.12±68.9 seconds in group R (p < .001). Conclusions Rocuronium 0.6 mg/kg can greatly shorten the tracheal intubation time and reduce the difficulty of surgery, and employment sugammadex can reverse residual muscle relaxation of rocuronium and optimize IONM conditions.
