Surgery 2024; 176:713-720. [PMID: 38890101 DOI: 10.1016/j.surg.2024.05.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 05/03/2024] [Accepted: 05/13/2024] [Indexed: 06/20/2024]
Abstract
BACKGROUND This study aimed to observe the occurrence of recurrent laryngeal nerve injury after McKeown esophagectomy for esophageal squamous cell carcinoma, as well as its recovery and influencing factors within 7 months after surgery. METHODS From July 2020 to July 2021, among all patients who underwent minimally invasive McKeown esophagectomy, 90 patients who developed vocal cord paralysis after surgery were included in the study. These patients underwent endoscopic vocal cord function assessment every 1 to 2 months and continued until 7 months postoperatively. RESULTS Among all 388 patients undergoing esophagectomy, 23.2% (90/388) of patients suffered postoperative vocal cord paralysis. Left, right, and bilateral injuries were confirmed in 73 (81.1%), 12 (13.3%), and 5 patients (5.6%), respectively. With a median recovery time being 183 days, the cumulative overall recovery rate was 65.4% at 7 months, 68.6% for the left side, 55.6% for the right, and 20.0% for bilateral injuries. In multivariable analysis, cervical paraoesophageal lymph node dissection and conventional thoracoscopic-assisted esophagectomy were demonstrated to be independent risk factors associated with non-recovery of vocal cord paralysis. CONCLUSIONS After intensive endoscopic follow-up, a cumulative vocal cord paralysis recovery rate of 65.4% within 7 months was observed in patients after minimally invasive McKeown esophagectomy. Cervical paraoesophageal lymph node dissection and conventional thoracoscopic-assisted esophagectomy were demonstrated to be risk factors hindering vocal cord paralysis recovery.

Is There Any Reliable Predictor of Functional Recovery Following Post-thyroidectomy Vocal Fold Paralysis? World J Surg 2023; 47:429-436.

Abstract
BACKGROUND Predicting definitive outcomes of post-thyroidectomy vocal fold paralysis (VFP) is challenging. We aimed to identify reliable predictors based on intraoperative neuromonitoring (IONM) and flexible fiberoptic laryngostroboscopy (FFL) findings. METHODS Among 1172 thyroid operations performed from April to December 2021, all patients who exhibited vocal fold paralysis (VFP) at post-operative laryngoscopy were included. IONM data, including type of loss of signal (LOS), were collected. Patients underwent FFL, with arytenoid motility assessment, at 15, 45 and 120 days post-operatively. Patients were divided into two groups: those who recovered vocal fold motility (VFM) by the 120th post-operative day (recovery group) and those who did not (non-recovery group). RESULTS Fifty-nine VFP cases (5.0% of total patients) met the inclusion criteria. Eight patients were lost at follow-up and were excluded. Overall, 9 patients were included in the non-recovery group (0.8% of total patients) and 42 in the recovery group. Among various predictive factors, only arytenoid fixation (AF) at the 15th post-operative day and Type I LOS were significant predictors for no VFM recovery (p = 0.007, RR = 9.739, CI:1.3-72.3 and p = 0.001, RR = 9.25, CI:2.2-39.3 for AF and Type I injury, respectively). The combination of type of LOS and arytenoid motility at the 15th post-op day yielded satisfactory predictive values for the progression of transient VFP to permanent. CONCLUSIONS Arytenoid motility at the 15th post-op day and type II LOS are associated with recovery of VFM. Type of LOS and FFL could be included in the follow-up protocols of patients with VFP to reliably predict clinical outcomes.

Abstract
OBJECTIVE The aim of the study was to evaluate voice and swallowing function following thyroid surgery, to identify dynamic changes during the follow-up period of 12-18 month and to find possible indicative signs of permanent or temporary vocal fold palsy. METHODS All participants (N = 110) were prospectively enrolled from the preoperative thyroid surgery patients between September 2013 and December 2016. All subjects underwent preoperatively, first week and 12-18 month postoperatively videolaryngostroboscopy, filled in subjective evaluation of voice (voice handicap index, [VHI]) and swallowing (swallowing impairment score) complaints. Acoustic voice analysis (AVA), maximum phonation time (MPT) measurement and perceptual voice evaluation were conducted. In the presence of laryngeal damage, additional first and sixth-month follow-up visits were planned. Patients, whom we suspected laryngeal nerve damage, underwent laryngeal electromyography 4 weeks after the operation. RESULTS On first postoperative week evaluation, no objective voice changes within patients with postoperatively intact laryngeal nerves were found. Subjective evaluations showed decline in VHI physical domain and increased strain in postoperative voice. Patients with postoperative nerve damage had a drastic decline in subjective voice quality (VHI all subscales and total score), AVA parameter jitter, MPT and perceptual voice quality. Subjective evaluation of swallowing revealed disturbances in all patients regardless of the nerve damage. We noticed remarkable differences in first week and first month visits between patients with permanent and temporary palsy in VHI total score and physical domain, MPT and perceptual breathiness and asthenia in voice. Regardless of the nerve injury, by the end of the follow-up period all changes had become statistically insignificant with the exception of perceptual evaluation of voice quality. CONCLUSIONS Patients with postoperative laryngeal nerve damage experience substantial deterioration of both subjective and objective voice quality with more extensive impairment in patients with permanent paralysis. Thyroid surgery causes subjective swallowing changes irrespective of laryngeal nerve damage. In patients without laryngeal nerve damage, swallowing function improves following thyroidectomy. Possible indicators for permanent paralysis are delayed recovery in the values of MPT and jitter and persistent perceptual breathiness and asthenia.

Abstract
OBJECTIVES Paralysis of the recurrent laryngeal nerves (RLNs), albeit decreased over the years, leaves the surgeon helpless as there is not much that can be done once it occurs. Nimodipine has been suggested as a remedy that could accelerate the recovery of the nerve. Our study aimed to examine the factors that affect the recovery rate (RR) and time to recovery (TTR) of post-thyroidectomy RLN paralysis, with an emphasis on the use of nimodipine. METHODS A total of 197 patients who had undergone thyroid and parathyroid surgeries were retrospectively reviewed from October 2016 to August 2019. Patients who had RLN paralysis following surgery were assessed. The medical records were retrospectively analyzed to look for possible factors that may influence RLN recovery. RESULTS A total of 289 nerves were at risk. Temporary RLN paralysis rate was 7.9% while 1.7% was permanent. Age (odds ratio [OR] = 4.8) and intra-operative extra-thyroid extension (OR = 9.0) were independent risk factors for RLN paralysis. The rate of recovery was 82.1%. Loss of signal (LOS; P = .066) was a factor trending for an impact on RR but not nimodipine (P > .05). The mean TTR was 32 days. LOS, nimodipine, and steroid use, among others, were factors trending for an impact on the TTR. CONCLUSION Although not reaching statistical significance, nimodipine and steroids might influence TTR but not the RR. Larger studies are warranted to address the effect of nimodipine on the outcome of RLN paralysis. LEVEL OF EVIDENCE 4 Laryngoscope, 2022.

Abstract
Importance Total thyroidectomy is associated with risks related to temporary hypocalcemia and vocal quality dysfunction. Dexamethasone has been proposed to have a physiological effect on hypocalcemia and voice quality. Objective To assess the effect of preoperative dexamethasone used to improve hypocalcemia and postthyroidectomy voice dysfunction. Design, Setting, and Participants This double-blind, parallel-group, placebo-controlled randomized clinical trial was conducted from January 15, 2014, to December 31, 2019, at the Department of Surgery, Holy Family Hospital in Rawalpindi, Pakistan. All patients with a benign thyroid condition and no preoperative corrected hypocalcemia and voice or vocal quality dysfunction were included. Patients were excluded if they had previous thyroid or neck surgery, known vocal cord dysfunction on laryngoscopy, hearing or voice problems, a history of gastroesophageal reflux, stomach ulcer disease, or contraindications to steroid use. Interventions Corrected serum calcium levels and Voice Analog Score defined and measured preoperatively. The dexamethasone group received a 2-mL intravenous dose of 8 mg of dexamethasone 60 minutes before the induction of anesthesia. In contrast, the placebo group received 2 mL of intravenous normal saline (0.9%) 60 minutes before the induction of anesthesia. Main Outcomes and Measures Evidence of hypocalcemia and voice dysfunction. Voice dysfunction was defined as a subjective score of less than 50 on a Voice Analog Score scale of 0 to 100 points. Results A total of 192 patients (mean [SD] age, 38.9 [12.4] years; 156 women [81.2%]) were included in the study, with 96 patients randomized to each study group (dexamethasone group, mean [SD] age, 39.2 [12.1] years; 75 women [78.1%]; placebo group, mean [SD] age, 38.5 [12.9] years; 81 women [84.5%]). In the first 24 hours after undergoing thyroidectomy, 47 patients (24.4%) developed hypocalcemia and 18 (9.4%) were symptomatic. At 3 days postthyroidectomy, 4 of 96 patients (4.2%) in the placebo group had hypocalcemia compared with no patients in the dexamethasone group. At 24 hours postthyroidectomy, 8 of 96 patients (8.3%) in the dexamethasone group had voice dysfunction compared with 32 of 96 patients (33.3%) in the placebo group. A total of 40 patients (20.8%) reported voice dysfunction. The absolute reduction in the rate of hypocalcemia at 24 hours was 24% (95% CI, 11.9%-35.2%) and at 3 days was 4.2% (-0.44% to 10.0%). The rate of symptomatic hypocalcemia was 19% lower in the dexamethasone group than in the placebo group (95% CI, 11.1%-27.7%). The rate of voice dysfunction was 25% lower in the dexamethasone group than in the placebo group (95% CI, 13.7%-35.7%). Conclusions and Relevance In this randomized clinical trial, a single preoperative dose of dexamethasone was safe and effective in reducing postoperative hypocalcemia and voice dysfunction rates in patients undergoing thyroidectomy.

Abstract
ABSTRACT Purpose: to estimate the prevalence of voice- and swallowing-related symptoms in women submitted to total thyroidectomy. Methods: a population-based, observational, cross-sectional, analytical study, based on a Brazilian national survey. A total of 252 women, aged 18 to 58 years, submitted to total thyroidectomy, residing in the five geographical regions of the country participated in the study. All of them answered the version of the Thyroidectomy-Related Voice Questionnaire translated and adapted into Brazilian Portuguese, besides questions on demographic and clinical issues. A descriptive analysis of the categorical and quantitative variables was conducted. The relationship between the total TVQ score and the independent variables was analyzed with the Mann-Whitney and Kruskal-Wallis tests. The significance level used was 5%. Results: the most prevalent symptoms were, tired voice, after talking for a long time (50%), and dry mouth/thirst (43.3%). The voice-related symptoms were more prevalent than those related to swallowing. The total TVQ score was not related to age group (p=0.141), profession (p=0.213), region of residence (p=0.303), time since surgery (p=0.955), and radiotherapy/radioiodine therapy (p=0.666). Conclusion: Brazilian women submitted to total thyroidectomy have a high prevalence of voice- and swallowing-related symptoms, the former being predominant.

Abstract
Objectives: This study is set to analyze clinicopathological factors predicting the recovery of unilateral vocal fold paralysis (UVP) in patients after thyroid gland surgery. The quality of voice was additionally assessed in these patients. Methods: The charts and videolaryngostroboscopy (VLS) examinations of 84 consecutive patients with a complete UVP after surgery of the thyroid gland were retrospectively reviewed. Patients were divided into 2 groups: patients who fully recovered from vocal fold paralysis and those who failed to recover after a follow-up of 12 months. The quality of voice was analyzed among other things by determining the Voice Handicap Index (VHI). Results: The UVP fully recovered in 52 of 84 (61.9%) patients. Positive mucosal waves (pMWs) on the paralyzed side, a minimal glottic gap <3 mm seen at the first postoperative VLS, age ≤50 years, and surgery duration ≤120 minutes were associated factors for a complete recovery of nerve function. The voice parameters improved independently from recovery of the paralysis in 90% of the patients. Conclusions: For patients with a poor prognosis of a UVP, early intervention may be beneficial. Thus, predicting factors for a full recovery of vocal fold motion would be a valuable tool. In our cohort, about 60% of recoveries could have been predicted using the above-mentioned parameters. Good quality of voice was independently reached in 90% of the cases.

Abstract
Thyroid cancer (TC) is the most common type of cancer in the endocrine system, and thyroidectomy is the preferred treatment. Complications associated are still common and 80% of patients complain of posterior neck pain. The aim of this study was to analyse the long-term musculoskeletal disorders in TC patients who had undergone thyroidectomy. An observational case-control study was carried out. Twenty-eight patients who had undergone thyroidectomy and 28 healthy control patients were included. Outcomes were collected 6 months after surgery and included: musculoskeletal neck disorders (neck range of movement, trigger points) and functional variables (pain intensity and disability). Significant differences were found between groups in flexion (p = 0.002) and extension (p = 0.005), with lower values in the thyroidectomy group. The number of trigger points was higher in the thyroidectomy group in both scalenes (p < 0.001), both sternocleidomastoids (p < 0.001), both upper trapezius (p = 0.005 and p = 0.008), right levator scapulae (p = 0.002) and both suboccipitalis (p = 0.002). Pain intensity (p < 0.001) and the Neck Outcome Scale subscales (p < 0.05) also presented significant differences. Thyroidectomy patients, 6 months after surgery, show a significant decrease in neck range of movement and an increase in the number of trigger points. They also show greater pain intensity and more disability.
