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
Voice change is a common complaint after thyroid surgery and has significant impacts on quality of life. The Korean Society of Laryngology, Phoniatrics, and Logopedics set up a task force team to establish guideline recommendations on education, care, and management related to thyroid surgery. The guideline recommendations include preoperative voice education, management of anticipated voice change during surgery, and comprehensive voice care after thyroid surgery, including in-depth information and up-to-date knowledge based on validated literature. The committee constructed 14 key questions (KQ) in three categories: preoperative (KQ1-2), intraoperative (KQ 3-8), and postoperative (KQ 9-14) management and developed 18 evidence-based recommendations. The Delphi survey reached an agreement on each recommendation. Detailed evidence profiles are presented for each recommendation. The level of evidence for each recommendation is classified into high, moderate, and low-quality. The recommendation's strengths are adjusted to consider the level of evidence resulting in the recommendation and are divided into strong and weak. The guidelines are primarily targeted toward physicians who treat thyroid surgery patients and speech-language pathologists participating in patient care. These guidelines will also help primary care physicians, nurses, healthcare policymakers, and patients improve their understanding of voice changes and voice care after thyroid surgery.

Neuromonitoring of the Recurrent Laryngeal Nerve Reduces the Rate of Bilateral Vocal Cord Dysfunction in Planned Bilateral Thyroid Procedures. J Clin Med 2021; 10:jcm10040740. [PMID: 33673313 PMCID: PMC7918228 DOI: 10.3390/jcm10040740] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Revised: 01/24/2021] [Accepted: 01/31/2021] [Indexed: 02/07/2023] Open
Abstract
Purpose: Bilateral vocal cord dysfunction (bVCD) is a rare but feared complication of thyroid surgery. This long term retrospective study determined the effect of intraoperative neuromonitoring (IONM) of the recurrent laryngeal nerve (RLN) during thyroid surgeries with regard to the rate of bVCD and evaluated the frequency as well as the outcome of staged operations. Methods: Retrospective analysis of prospectively documented data (2000–2019) of a tertiary referral centers’ database. IONM started in 2000 and, since 2010, discontinuation of surgery was encouraged in planned bilateral surgeries to prevent bVCD, if non-transient loss of signal (ntLOS) occurred on the first side. Datasets of the most recent 40-month-period were assessed in detail to determine the clinical outcome of unilateral ntLOS in planned bilateral thyroid procedures. Results: Of 22,573 patients, 65 had bVCD (0.288%). The rate of bVCD decreased from 0.44 prior to 2010 to 0.09% after 2010 (p < 0.001, Chi2). Case reviews of the most recent 40 months period identified ntLOS in 113/3115 patients (3.6%, 2.2% NAR), of which 40 ntLOS were recorded during a planned bilateral procedure (n = 952, 2.1% NAR). Of 21 ntLOS occurring on the first side of the bilateral procedure, 15 procedures were stopped, subtotal contralateral resections were performed, and thyroidectomy was continued in 3 patients respectively, with the use of continuous vagal IONM. Eighteen cases of VCD were documented postop, and all but one patient had a full recovery. Seven patients had staged resections after 1 to 18 months (median 4) after the first procedure. Conclusion: IONM facilitates reduced postoperative bVCD rates. IONM is, therefore, recommendable in planned bilateral procedures. The rate of non-complete bilateral surgery after intraoperative non-transient LOS was 2%.

Effect of voice therapy with or without transcutaneous electrical stimulation on recovery of injured macroscopically intact recurrent laryngeal nerve after thyroid surgery. Eur Arch Otorhinolaryngol 2020; 277:933-938. [PMID: 31980883 PMCID: PMC7031404 DOI: 10.1007/s00405-020-05806-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2019] [Accepted: 01/18/2020] [Indexed: 10/28/2022]
Abstract
PURPOSE Electrical stimulation-supported therapy is an often used modality. However, it still belongs to experimental methods in the human larynx. Data are lacking with which to evaluate the real effect in recurrent laryngeal nerve injury. The aim of this study was to investigate whether transcutaneous electrical stimulation added to voice therapy has a beneficial effect compared to voice therapy alone on vocal fold movement recovery in the case of an injured macroscopically intact recurrent laryngeal nerve. METHODS Adults with unilateral vocal fold paralysis after thyroidectomy, in which the recurrent laryngeal nerve was left macroscopically intact, were included in this case-control study performed in tertiary referral hospital between September 2006 and June 2018. Among 175 eligible participants, 158 were included. Compliance with 6 months follow-up was 94.3%. INTERVENTIONS medicament therapy and voice therapy (group 1) vs. medicament therapy and voice therapy and transcutaneous electrical stimulation (group 2). MAIN OUTCOME vocal fold movement. RESULTS A total of 149 patients were included in the analysis (group 1, 89 patients; group 2, 60 patients). The groups were homogenous. In groups 1 and 2, 64% and 60% of vocal folds, respectively, were improved after 6 months (P = 0.617). No difference was found between patients who improved and patients who did not improve. CONCLUSIONS Adding transcutaneous electrical stimulation to voice therapy provided no beneficial effect on the recovery of vocal fold movement. Therefore, its indications should be re-evaluated; it is questionable whether stimulation should be routinely recommended.

Abstract
Thyroidectomy has been used for the treatment of thyroid disease for more than 100 years. In spite of the advancement of surgical techniques, there is still a risk of laryngeal nerve injury. The risk of partial or complete injury still depends on some surgical and disease-related factors. The aim of this study is to show the partial injury and to establish these risk factors via laryngeal electromyographic analysis (LEMG) in postthyroidectomy patients with normal vocal cord motion and mucosal anatomy. Patients who had undergone thyroid surgery were enrolled in this prospective study. LEMG analysis was performed to all patients with normal vocal cord mobility preoperatively and was repeated after the first and the third months of surgery. Thyroarytenoid (TA) and cricothyroid (CT) muscles were used to evaluate recurrent and external branch of superior laryngeal nerves, respectively. Four of the 32 patients had mild-to-moderate degrees of partial LEMG changes during preoperative LEMG analysis of TA and CT muscles on each side. After 3 months of surgery, there was a statistically significant worsening of LEMG findings in the right and left external branches of superior and left recurrent laryngeal nerves. Disease and surgery-related risk factors were analyzed. However, there was no significant relationship on the progression of LEMG findings according to these parameters. This is the first prospective study which supports the risk of progression of LEMG changes in patients with normal laryngoscopic examination after thyroid surgery. No reliable significant risk factor was found influencing the LEMG progression.

Abstract
BACKGROUND Unilateral vocal fold paresis (UVFP) significantly deteriorates the patient's quality of life. The leading role in the rehabilitation of the patients presenting with UVFP belongs to stimulation therapy which consists in the activation of muscle re-innervation of the larynx and the compensatory mechanisms allowing to achieve the most complete closure of the vocal folds during phonation. AIM The objective of the present study was the optimization of the conservative treatment of patients with UVFP. MATERIAL AND METHODS Fifty patients at the age varying from 18 to 70 years presenting with UVFP (the duration of the disease less than 6 months underwent the comprehensive treatment including electrostimulation of the larynx, vitamin therapy, and speech therapy. The patients were divided into two groups: A and B comprised of 25 subjects each. Those of Group A were given, in addition to the standard treatment, a 1.5 month-long course of Neuromidin therapy. The results of the treatment were evaluated with the use of laryngostroboscopy, flowmetry, the GRBAS scale, acoustic voice analysis (lingWaves), and the VHI questionnaire. RESULTS The restoration of vocal fold mobility was achieved in 20% and 8% of the patients of groups A and B respectively. The clinical effect was absent in 12% of the patients in Group A and 28% of the patients in Group B. The differences between groups were statistically significant (p<0.05). In the remaining cases, the positive dynamics of the flowmetric characteristics, GRBAS and VHI data, maximum phonation time, Jitter, DSI, frequency and dynamic ranges as well as the intensity of voice were documented in 68% of patients in Group A and 64% of patients in Group B). CONCLUSION The results of the study confirm the usefulness of the combined treatment of UVFP consisting of electrostimulation of the larynx together with speech therapy and application of cholinergic drugs. The addition of Neuromidin to the conventional scheme of conservative treatment can further improve its efficiency from 72% to 88%.

Abstract
Objectives: We present cases of transient true vocal fold (TVF) immobility caused by well-differentiated thyroid carcinoma (WDTC), and review the literature concerning management of WDTC invading the recurrent laryngeal nerve (RLN). Methods: A description of the clinical course of 2 patients with WDTC and transient TVF immobility is presented in the context of a review of the literature concerning locally advanced WDTC with extrathyroidal extension and RLN involvement. Results: Both patients had papillary thyroid carcinoma with ipsilateral TVF paralysis that resolved completely before operation. During the operation, the RLN was found to be grossly involved with disease and inseparable from the tumor, necessitating resection. Review of the literature revealed the following points that should be considered when confronting an RLN invaded by WDTC. 1) Benign disease can mimic invasive WDTC and must be ruled out. 2) RLN invasion does not carry the same prognostic implications as other categories of extrathyroidal extension of WDTC. 3) RLN sacrifice does not increase the overall survival rate. 4) There is no evidence that a paralyzed RLN will regain function when preserved. 5) The majority of RLNs that function before operation can be expected to function after the operation if preserved. Conclusions: Resolution of TVF paralysis should not reduce suspicion of RLN involvement by WDTC. When RLN involvement is discovered during operation, every attempt should be made to preserve a functioning RLN.

Abstract
Objectives To establish the incision length for thyroid surgery that optimizes access and cosmesis. Study Design and Setting Prospective study from January 2003 to June 2004. All thyroidectomies were included. Exclusion criteria were concomitant neck dissections, previous surgery, and those performed endoscopically. The first 40 cases were attempted through a 5 cm incision and the second 40 through a 4 cm incision. Methods In both groups, the size of the incision was compared with the thyroid's weight and histology. Results Two subtotal, 22 total, and 56 hemithyroidectomies were performed. In the first group, median gland weight was 39.5 gm and 62.5% of these were removed through a 5 cm incision. In the second group, median gland weight was 34 gm and 75% were removed through a 4 cm incision. Conclusion A 4 cm incision provides adequate access for the majority of thyroidectomies in our cohort. Significance The minimal incision thyroidectomy is a useful addition to the thyroid surgeon's armamentarium. EBM rating: B-3b

Abstract
Objective To estimate the patterns of use of intraoperative recurrent laryngeal nerve (RLN)-monitoring devices during thyroid surgery by otolaryngologists in the United States. Methods A questionnaire was mailed to 1685 randomly selected otolaryngologists, representing approximately half of all otolaryngologists currently practicing in the United States. Topics covered included training history and current practice setting, use and characteristics of use of RLN monitoring during thyroid surgery, as well as history of RLN injury and/or subsequent lawsuits. X 2 test was used to examine associations between monitor usage and dependent variables, and odds ratios calculated by logistic regression were used to refine the magnitude of these associations. RESULTS: A total of 685 (40.7%) of questionnaires were returned, and 81 percent (555) of respondents reported performing thyroidectomy. Of those, only 28.6 percent (159) reported using intraoperative monitoring for all cases. Respondents were 3.14 times more likely to currently use intraoperative monitoring if they used it during their training. Surgeons currently using intraoperative RLN monitoring during thyroidectomy were 41 percent less likely to report a history of permanent RLN injury. Further information about surgeon background and rationale for decisions regarding RLN monitor usage are discussed. Conclusions Presently, the majority of otolaryngologists in the United States do not report regular usage of RLN monitoring in their practices. Surgeon background and training, more so than surgical volume, significantly influenced the use of intraoperative RLN monitoring.

Abstract
Background We evaluated the efficacy of a new anesthetic technique termed ultrasound-guided capsule-sheath space block (CSSB) combined with anterior cervical cutaneous nerve block (CCNB) for thyroidectomy. Methods The study included two parts: Part one was an imaging study to determine technique feasibility. The CSSB was performed on five healthy volunteers by introducing the needle 0.5 cm lateral to the probe under in-plane needle ultrasound guidance. After puncture of the false capsule and its subsequent contraction with the true capsule of thyroid, 10 mL of contrast medium was deposited slowly in the capsule-sheath space. The CCNB was performed bilaterally as follows: Under ultrasound guidance, a subcutaneous injection was made along the sternocleidomastoid using 10 mL of contrast medium which was followed by a girdle-shaped picchu raised from the cricoid cartilage to supraclavicular region. The spreading pattern of contrast medium was imaged using computed tomographic scanning. In part two (a clinical case series) the technique efficacy was evaluated. Seventy-eight patients undergoing thyroidectomy had ultrasound-guided CSSB and CCNB with local anesthetics. The sensory onset of CCNB, intraoperative hemodynamic parameters, and analgesic effect were assessed and complications were noted. Results The distribution of contrast medium was well defined. In part two the onset time of CCNB was 2.2 ± 0.7 min, and the hemodynamic parameters remained stable intraoperatively. The recall of visual analogue scale scores during surgery was 2 [1–4] for median (range). The patients’ and surgeons’ satisfaction scores were 2 [1–4] and 1 [1–3] for median (range). No serious complications occurred. Conclusions Combining ultrasound-guided CSSB and CCNB is a feasible, effective and safe technique for thyroidectomy.

Abstract
CONCLUSION Primary intraoperative recurrent laryngeal nerve (RLN) reinnervation techniques demonstrated significant voice improvement at 24 months postoperatively and could be an effective alternative treatment for thyroidectomy-related permanent unilateral vocal fold paralysis (VFP). OBJECTIVES To assess the long-term efficacy of intraoperative RLN reinnervation techniques in the management of thyroidectomy-related unilateral VFP. METHODS A prospective study was conducted from January 2008 to June 2012 at Soonchunhyang University Bucheon Hospital. Nineteen patients who underwent RLN reinnervation with either direct reinnervation (neurorrhaphy) or ansa cervicalis to RLN (ansa-RLN) anastomosis and completed subjective and objective voice measurement over a 1-year follow-up period were included in this study. RESULTS The causes of VFP were cancer involving the RLN (68.4%, 13/19) and iatrogenic nerve transection (31.5%, 6/19). Reinnervation techniques were direct neurorrhaphy (63.2%, 12/19) and ansa-RLN anastomosis (36.8%, 7/19). Subjective parameters such as the Voice Handicap Index (VHI), posterior glottic closure, and mucosal wave demonstrated significant improvement 6 months postoperatively, and the majority of parameters remained stable up to 24 months (p < 0.05). Objective parameters, such as maximum phonation time (MPT), jitter, shimmer, and the harmonics-to-noise ration (HNR), demonstrated significant improvement at 12 months and most remained stable at 24 months (p < 0.05).

Abstract
It is well accepted that recurrent laryngeal nerve paralysis is a severe complication of esophagectomy or lymphadenectomy performed adjacent to the recurrent laryngeal nerves. Herein, determination of the effectiveness of implementing continuous recurrent laryngeal nerve monitoring to reduce the incidence of recurrent laryngeal nerve paralysis after esophagectomy was sought. A total of 115 patients diagnosed with esophageal cancer were enrolled in the thoracic section of the Tangdu Hospital of the Fourth Military Medical University from April 2008 to April 2009. Clinical parameters of patients, the morbidity, and the mortality following esophageal resection were recorded and compared. After the surgery, a 2-year follow up was completed. It was found that recurrent laryngeal nerve paralysis and postoperative pneumonia were more frequently diagnosed in the patients that did not receive continuous recurrent laryngeal nerve monitoring (6/61 vs. 0/54). Furthermore, positive mediastinal lymph nodes (P = 0.015), total mediastinal lymph nodes (P < 0.001), positive total lymph nodes (P = 0.027), and total lymph nodes (P < 0.001) were more often surgically removed in the patients with continuous recurrent laryngeal nerve monitoring. These patients also had a higher 2-year survival rate (P = 0.038) after surgery. It was concluded that continuous intraoperative recurrent laryngeal nerve monitoring is technically safe and effectively identifies the recurrent laryngeal nerves. This may be a helpful method for decreasing the incidence of recurrent laryngeal nerve paralysis and postoperative pneumonia, and for improving the efficiency of lymphadenectomy.

Abstract
BACKGROUND This prospective study investigated the efficacy of injection laryn-goplasty in the management of postthyroidectomy vocal cord paralysis (VCP). METHODS From March 2005 to December 2008, 174 consecutive injection laryngoplasties were performed in patients with unilateral glottic insufficiency. This included 34 patients with post-thyroidectomy VCP: 15 with temporary VCP and 19 with permanent VCP. Percutaneous injection was performed under local anesthesia into the vocalis muscle, using disposable 25G-long needles through the cricothyroid membrane or directly through the thyroid cartilage. Patients completed the acoustic, aerodynamic, perceptual, stroboscopic, and voice handicap index evaluations before and at 3 and 6 months after the injection. RESULTS All injection laryngoplasty could be performed under local anesthesia without morbidity. Acoustic and perceptual parameters (overall grade of hoarseness, roughness, breathiness, asthenia, and strain), maximum phonation time, jitter, and shimmer, voice handicap index, and grades of mucosal waves and glottic closure were significantly improved after the injection and they remained stable over 6 months in both the temporary VCP and permanent groups (p < 0.05). CONCLUSIONS Based on these preliminary results, injection laryngoplasty improved the voice, and voice-related quality of life in patients with post-thyroidectomy VCP. It is a simple, safe, and useful method for rehabilitating post-thyroidectomy VCP patients.

Abstract
Endocrine disease has been recognised for thousands of years, but surgical treatment of endocrine disorders has only been widely used in the past century. Surgery is an effective treatment for hyperfunctioning glands and benign and malignant tumours. Advances in surgical technique have led to the development of short and safe operations with a high cure rate, and recent studies have not only assessed the success of the operations but also have focused on how these diseases affect patient-reported quality of life before and after surgery. In this Review, we summarise current approaches to surgical treatment of thyroid and parathyroid disease, focusing on how these approaches both preserve function and improve quality of life after surgery.

Abstract
OBJETIVO: O estudo foi transversal e retrospectivo por meio dos registros fotográficos, nos transoperatórios de 53 tireoidectomias totais e parciais, realizadas entre janeiro de 2002 a agosto de 2006, em pacientes portadores de doenças benignas e malignas da tireóide. RESULTADOS: Foram obtidas imagens de 111 glândulas paratireóides. Das 67 superiores, 65 (97%) estavam envolvidas pelo fino e irregular tecido adiposo peri-glandular. Das 44 inferiores, 41 (93,1%) estavam parcial ou totalmente envoltas pela esparsa gordura aderida à cápsula tireóide. A escolha da via de acesso e o cuidado para evitar hemorragias são dois itens que evitam maiores dificuldades. Acrescem-se os rigores da técnica com a ligadura do pedículo superior, sendo realizada em primeiro lugar, seguida da mobilização do lobo tireóideo em sentido medial. Esses gestos possibilitam a melhor identificação das paratireóides. CONCLUSÃO: É indispensável conservar o tecido adiposo aderido à cápsula tireóidea, onde se alojam mais de 90% das paratireóides. O manuseio cirúrgico dessa delgada lâmina adiposa provoca a mudança da cor das paratireóides, tornando-as amarronzadas, destacando-as entre o amarelo-ouro da gordura e impondo maior atenção ao cirurgião.

Abstract
BACKGROUND The nature and indications for thyroid surgery vary and a perceived risk of haemorrhage post-surgery is one reason why wound drains are frequently inserted. However when a significant bleed occurs, wound drains may become blocked and the drain does not obviate the need for surgery or meticulous haemostasis. The evidence in support of the use of drains post-thyroid surgery is unclear therefore and a systematic review of the best available evidence was undertaken. OBJECTIVES To determine the effects of inserting a wound drain during thyroid surgery, on wound complications, respiratory complications and mortality. SEARCH STRATEGY We searched the following databases: Cochrane Wounds Group Specialised Register and the Cochrane Central Register of Controlled Trials (CENTRAL) (issue 1, 2007); MEDLINE (2005 to February 2007); EMBASE (2005 to February 2007); CINAHL (2005 to February 2007) using relevant search strategies. SELECTION CRITERIA Only randomised controlled trials were eligible for inclusion. Quasi randomised studies were excluded. Studies with participants undergoing any form of thyroid surgery, irrespective of indications, were eligible for inclusion in this review. Studies involving people undergoing parathyroid surgery and lateral neck dissections were excluded. At least 80% follow up (till discharge) was considered essential. DATA COLLECTION AND ANALYSIS Studies were assessed for eligibility and data were extracted by two authors independently, differences were resolved by discussion. Studies were assessed for validity including criteria on whether they used a robust method of random sequence generation and allocation concealment. Missing and unclear data were resolved by contacting the study authors. MAIN RESULTS 13 eligible studies were identified (1646 participants). 11 studies compared drainage with no drainage and found no significant difference in re-operation rates; incidence of respiratory distress and wound infections. Post-operative wound collections needing aspiration or drainage were significantly reduced by drains (RR 0.51, 95% CI 0.27 to 0.97), but a further analysis of the 4 high quality studies showed no significant difference (RR 1.82, 95% CI 0.51 to 6.46). Hospital stay was significantly prolonged in the drain group (WMD 1.18 days, 95% CI 0.73 to 1.63).Eleven studies compared suction drain with no drainage and found no significant difference in re-operation rates; incidence of respiratory distress and wound infection rates. The incidence of collections that required aspiration or drainage without formal re-operation was significantly less in the drained group (RR 0.48, 95% CI 0.25 to 0.92). However, further analysis of only high quality studies showed no significant difference (RR 1.78, 95% CI 0.44 to 7.17). Hospital stay was significantly prolonged in the drain group (WMD 1.20 days, 95% CI 0.77 to 1.63). One study compared open drain with no drain. No participant in either group required re-operation. No data were available regarding the incidence of respiratory distress, wound infection and pain. The incidence of collections needing aspiration or drainage without re-operation was not significantly different between the groups and there was no significant difference in length of hospital stay. One study compared suction drainage with passive closed drainage. None of the participants in the study needed re-operation and data regarding other outcomes were not available. Two studies (180 participants) compared open drainage with suction drainage. One study reported wound infections and minor wound collections, both were not significantly different. The other study reported wound collections requiring intervention and hospital stay; both were not significantly different. None of the participants in either study required re-operation. Data regarding other outcomes were not available. AUTHORS' CONCLUSIONS There is no clear evidence that using drains in patients undergoing thyroid operations significantly improves patient outcomes and drains may be associated with an increased length of hospital stay. The existing evidence is from trials involving patients having goitres without mediastinal extension, normal coagulation indices and the operation not involving any lateral neck dissection for lymphadenectomy.

Abstract
Reports in the literature suggest that the rate of transient and permanent vocal fold immobility (VFI) after thyroid surgery is 4% to 7% and 1% to 4%. The intraoperative use of nerve integrity monitors has been advocated to reduce the incidence of VFI during thyroid surgery. The purpose of this study was to compare postoperative VFI after unmonitored and monitored thyroid surgical procedures. The charts of 136 consecutive patients who underwent thyroid surgery from 1998 to 2003 were retrospectively surveyed. Fifty-four patients had total thyroidectomies, bringing the total recurrent laryngeal nerves (RLNs) dissected to 190. Three of 190 (1.6%) and 7 of 190 (3.7%) RLNs dissected had permanent and transient vocal fold dysfunction. Overall, 107 RLNs were unmonitored compared with 83 RLNs that were monitored. Unmonitored and monitored RLNs had a 4 of 83 (4.8%) versus 3 of 107 (2.8%) rate of transient VFI (P > 0.05). Unmonitored and monitored RLNs had a 1 of 107 (0.9%) versus 2 of 83 (2.4%) rate of permanent VFD (P > 0.05). Electrophysiologic RLN monitoring was not demonstrated in this study to reduce the incidence of transient or permanent VFI after thyroid surgery. Electrophysiologic RLN integrity does not always translate into clinical postoperative vocal fold mobility. Electrophysiologic RLN monitoring may support that the RLN was not severed in the patient with postoperative VFI.

Abstract
Intraoperative cranial nerve monitoring can be an effective adjunct in otolaryngology-head and neck surgery. Monitoring is not considered standard of care, despite indications of cost effectiveness and improved functional outcomes. Lessons learned performing facial nerve monitoring are applicable to upper and lower cranial motor nerves. Auditory nerve monitoring can be modified accord-ing to need for selected otologic and neurotologic surgery. Process standardization and effective communication can lead to improved patient outcomes.

Abstract
The principles of successful parathyroid surgery, regardless of the approach, demand a clear understanding of the philosophy behind the surgical exploration. A systematic approach, founded in science and refined by experience, is necessary to achieve long-term, reproducible surgical success. This article discusses the underlying logic and the advantages and disadvantages of the two basic approaches to parathyroid pathology: unilateral and bilateral cervical exploration. The authors do not to advocate a particular technique;instead, they provide a conceptual framework to surgical parathyroid disease upon which more advanced discussion can be built.
