Abstract
Objective Bilateral selective reinnervation of the larynx aims to restore both vocal cord tone and abductor movements in patients with bilateral vocal cord palsy. Methods Four females and one male treated by bilateral selective reinnervation of the larynx were included in the present study. In all cases, both posterior cricoarytenoid muscles were reinnervated using the C3 right phrenic nerve root through the great auricular nerve graft, while adductor muscle tone was bilaterally restored using the thyrohyoid branches of the hypoglossal nerve through transverse cervical nerve grafts. Results After a minimum follow-up of 48 months, all patients were successfully tracheostomy free and had recovered normal swallowing. At laryngoscopy, the first patient recovered a left unilateral partial abductor movement, the second had complete bilateral abductor movements, the third did not show improvements of abductor movements, but symptomatology was improved, the fourth recovered partial bilateral abductor movements and the fifth case did not show improvements and needed posterior cordotomy. Conclusions Bilateral selective laryngeal reinnervation, although a complex surgical procedure, offers a more physiologic recovery in the treatment of bilateral vocal fold paralysis. Selection criteria still needs to be precisely defined to avoid unexpected failures.

Abstract
Objectives To determine the decannulation rate (DR) and revision surgery rate after surgery for bilateral vocal fold paralysis (BVFP). Data Sources Five databases (MEDLINE, PubMed, Embase, Web of Science, Scopus) were searched for the period 1908-2020. Methods The systematic literature review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Data were pooled using a random-mixed-effects model. Randomized controlled trials and non-randomized studies (case-control, cohort, and case series) were included to assess DR and revision surgery rate after different surgical techniques for treatment of BVFP. Results The search yielded 857 publications, of which 102 with 2802 patients were included. DR after different types of surgery was: arytenoid abduction (DR 0.93, 95%-confidence interval [CI], 0.86-0.97), endolaryngeal arytenoidectomy (DR 0.92, 95%-CI, 0.86-0.96), external arytenoidectomy (DR 0.94; 95%-CI, 0.71-0.99), external arytenoidectomy and lateralisation (DR 0.87; 95%-CI, 0.73-0.94), laterofixation (DR 0.95; 95%-CI, 0.91-0.97), posterior cordectomy (DR 0.97, 95%-CI, 0.94-0.99), posterior cordectomy and arytenoidectomy (DR 0.98, 95%-CI, 0.93-0.99), posterior cordectomy and subtotal arytenoidectomy (DR 0.98, 95%-CI, 0.88-1.00), posterior cordotomy (DR 0.96, 95%-CI, 0.84-0.99), reinnervation (0.69, 95%-CI, 0.12-0.97), subtotal arytenoidectomy (DR 1.00, 95%-CI, 0.00-1.00) and transverse cordotomy (DR 1.0, 95%-CI, 0.00-1.00). No significant difference between subgroups for DR could be found (Q = 15.67, df = 11, p = 0.1540). The between-study heterogeneity was low (τ2 = 2.2627; τ = 1.5042; I2 = 0.0%). Studies were at high risk of bias. Conclusion BLVP is a rare disease and the study quality is insufficient. The existing studies suggest a publication bias and the literature review revealed that there is a lack of prospective controlled studies. There is a lack of standardized measures that takes into account both speech quality and respiratory function and allows adequate comparison of surgical methods.

Abstract
The objective of the present study was to consider the currently available methods for the diagnostics and treatment of the patients presenting with bilateral paralysis of the larynx of various etiologies. We undertook the analysis of the publications in the domestic and foreign scientific literature concerning diagnosis and treatment of bilateral paralysis of the larynx. It was found that despite the existing modern high-tech diagnostic technologies and the variety of surgical methods for the treatment of this condition, the problem of diagnostics, management, and rehabilitation of the patients suffering from bilateral paralysis of the larynx remains a serious challenge for the researchers and clinicians that requires further investigation of this pathology. For the correct and timely diagnosis of bilateral paralysis of the larynx, the comprehensive evaluation of the functional state of the neuromuscular apparatus of the larynx is necessary. The key prerequisites for the success of the surgical intervention are its timeliness and the choice of the optimal surgical modalities.

Abstract
Sixty-nine patients underwent subtotal carbon dioxide laser arytenoidectomy for treatment of bilateral vocal fold immobility between 1985 and 2000. The population included 69 patients whose mean age was 56 years (SD, 16 years; range, 11 to 82 years). The mean follow-up was 50 months (SD, 44 months; range, 1 to 181 months). The overall postoperative peak expiratory/peak inspiratory flow ratio (normal value, 1) significantly improved (closer to 1; p = .0036). Voice analyses were also undertaken for 27 patients, almost exclusively after operation, given the context of initial emergency. The maximum phonation time averaged 6.57 seconds (median, 6 seconds). The phonation quotient remained high, with a mean of 503 (median, 440), and the mean conversational voice intensity remained around 59 dB. The median frequency analysis type was 3. The advantage of subtotal arytenoidectomy lies in the fact that it maintains a certain degree of rigidity along the posterior limit of the arytenoid frame, preventing inward collapse of the mucosa and thus lowering the risk of aspiration.

Abstract
OBJECTIVES To perform a systematic literature review to evaluate the type and timing of therapy for vocal fold paresis/paralysis after thyroidectomy and develop a primary decision-making pathway. STUDY DESIGN Meta-analysis. METHODS Four databases and one journal were searched using the key words of "thyroidectomy," "vocal cord paresis/paralysis," and "therapy." Study quality was evaluated using the Cochrane Collaboration's risk of bias tools. Data regarding type and timing of therapy were extracted from 39 articles. Odds ratios (ORs), relative risk (RR), 95% confidence interval, and heterogeneity were recorded. Logistic regression analysis was performed to determine the relationships between timing and OR/RR. RESULTS Among the 13 studies investigating unilateral paresis/paralysis, five focused on early therapy (0-6 months). In these studies, the OR for clinical heterogeneity was significantly higher after neurolysis than after injection laryngoplasty and voice training (Q = 17.002, I(2) = 78%, P = 0.000), and the RR for heterogeneity was significantly higher after injection laryngoplasty at ≥12 months than <12 months (Q = 9.984, I(2) = 89.9%, P = 0.002). In the 26 studies that investigated bilateral paresis/paralysis, the OR for heterogeneity was significantly higher for bilateral posterior cordectomy than for endolaryngeal laterofixation (Q = 3.510, I(2) = 71.5%, P = 0.061) and laser arytenoidectomy with posterior cordectomy (Q = 2.90, I(2) = 65.6%, P = 0.088). CONCLUSIONS For unilateral vocal fold paresis/paralysis after thyroidectomy, we recommend absorbable mass injection laryngoplasty, voice training, and neurolysis during the first 12 months but laryngeal reinnervation after 12 months. For bilateral vocal fold paresis/paralysis, we recommend early laterofixation and combined laser arytenoidectomy with posterior cordectomy after 12 months.

Abstract
INTRODUCTION Bilateral vocal cord paralysis is caused by the damage of both recurrent laryngeal nerves. Such a pathology is not commonplace in the ordinary medical practice. It most often occurs as a complication after the thyroid gland surgery or thyroid re-surgery. In the case of bilateral vocal cord paralysis the treatment of the patient includes performing immediate tracheotomy or one of the surgeries aiming at widening the glottis because of dyspnea caused by the upper respiratory tract obstruction on the glottis level. AIM The comparison of efficacy and usefulness of two surgical techniques performed to widen the glottis – laser arytenoidectomy with posterior cordectomy and laterofixation. MATERIAL AND METHODS The research was carried out on the group of 57 patients suffering from bilateral vocal cord paralysis who, in the period of 1997–2009, underwent treatment in ENT Department in Zabrze Medical University of Silesia in Katowice. The first group included 36 patients who underwent laser arytenoidectomy with posterior chordectomy. The second group included 21 patients who underwent laterofixation. All of the patients treated with the laser arytenoidectomy with posterior cordectomy and laterofixation were subjected to respiratory system ventilation examinations before the procedure of widening the glottis and after the healing, at least 4 months after the surgery. Making self-evaluation, each of the patients answered a question concerning the improvement of their breathing comfort after the surgery. The patients from both groups underwent the vocal apparatus examination which included: subjective perceptive voice analysis according to GRBAS scale, videolaryngostroboscopy, evaluation of the maximum phonation time, self-evaluation survey of the post-surgical voice quality. RESULTS Among 57 patients suffering from bilateral vocal cord paralysis and operated by arytenoidectomy with posterior cordectomy (group I) and laterofixation (group II), a subjective improvement of the comfort of living was achieved which resulted in the possibility of making more physical activities. From the first group, 35 out of 36 patients were decannulated. In the second group, both patients who had previously undergone tracheotomy were successfully decannulated. There were no statistically significant differences in the increase of selected ventilation markers between the patients who underwent laser arytenoidectomy and those who underwent laterofixation. There were no substantial discrepancies in the perceptive voice analysis in GRBAS scale between the patients after laser arytenoidectomy and those treated with the technique of laterofixation. When asked about their post-surgical voice quality, the patients of the first and the second group rated their voice as worse than before the surgery. CONCLUSION Both surgical techniques, laser arytenoidectomy with posterior cordectomy and laterofixation, are efficient and useful in widening the glottis in the case of bilateral vocal cord paralysis. The improvement of the ventilation markers allows the growth in the comfort of living, restoration of the physiological respiratory tract and decannulation of the patients who had undergone tracheotomy. The deterioration of the voice quality is characteristic of both surgical techniques.

Abstract
Unilateral recurrent nerve paralysis leads to glottic insufficiency, significantly reducing vocal ability. Due to its unusually long course, the recurrent laryngeal nerve is prone to iatrogenic lesions involves many medical fields generally with little expertise in voice disorders. Whenever the etiology is uncertain, a complete diagnostic work-up is mandatory. Indirect laryngoscopy confirms the diagnosis. Laryngeal electromyography is of great value because it differentiates between paralysis and ankylosis of the cricoarytenoid joint. Moreover in many cases laryngeal electromyography yields a reliable prognosis of clinical outcome. While unfavorable results can be predicted with high accuracy, correct prognosis of complete recovery is more difficult. Speech therapy is the treatment of choice in cases of unilateral recurrent nerve palsy. Patients with persistent glottal gap may express the wish for surgical voice rehabilitation. Nowadays a broad spectrum of endoscopic and open approaches are available for this purpose. This review describes advanced techniques of voice-improving surgery available in specialized centers today.

Abstract
Ordinary clinical manifestation of the patient with bilateral vocal fold paralysis is inability of abducting the cords with a result of narrowing the glottic space, causing inspiratory stridor and mild dysphonia. Such patients can be life threatened due to narrowing airway. Some kind of surgery has to be performed on these patients in order to enlarge the airway. When we treat patients with OPG, the most reasonable way is to gradually enlarge airway at glotic level and there are several surgical methods for achieving this. The least agresive and the safest procedures are posterior transversal cordectomy (PTC) or medial arytenoidectomy (MA), after which we can perform extended versions of some of these methods or combination of both. Bilateral vocal fold paralysis has to be diagnostically different from stenosis of posterior commissure, even though the procedures such as medial arytenoidectomy, posterior transversal cordectomy and total arytenoidectomy can be performed in both cases. The patients have to be explained that the aim of the procedure is to enlarge airway to the detriment of voice quality and voice capabilities.

Abstract
OBJECTIVES We performed a prospective study to assess respiratory function and voice quality before and after laser microsurgical bilateral posterior cordectomy performed for chronic airway obstruction in patients with bilateral vocal fold paralysis. METHODS In 17 patients a laser microsurgical posterior cordectomy was performed as an immediate bilateral approach. Roughness, breathiness, hoarseness, and dyspnea were evaluated both subjectively (on a scale from 0 to 3) and objectively (body plethysmography, computerized voice analysis: Göttingen Hoarseness Diagram). RESULTS After laser surgery, the patients' respiratory function was significantly increased and was sufficient for all activities of daily living. The body plethysmographic measure of airway resistance had superior descriptive power and correlated significantly with the clinical degree of dyspnea (scale 0 to 3). Pretreatment and posttreatment impairment of voice quality was objectively documented with the Göttingen Hoarseness Diagram; the phonatory results measured with it correlated significantly with the subjective clinical evaluation of hoarseness. Aphonia did not occur. CONCLUSIONS A bilateral approach for laser microsurgical posterior cordectomy combines excellent airway improvement and satisfactory voice preservation. In bilateral vocal fold paralysis, pretreatment and posttreatment clinical data should be evaluated by objective measures.

Abstract
Bilateral arytenoid cartilage fixation (ACF) closely resembles vocal cord immobility due to recurrent laryngeal nerve paralysis (RLNP). This study sought to determine the etiologic differences between these two entities and to derive conclusions about treatment. The charts of 218 consecutive adult patients with immobility of both vocal cords requiring surgery for airway restoration were reviewed. The results of laryngeal electromyography and laryngotracheoscopy were used to distinguish ACF from RLNP. In 186 patients (85.3%), RLNP was identified. Of these, 154 paralyses (82.8%) were caused by surgical interventions, 5 (2.7%) were caused by previous intubation, 16 (8.6%) were caused by various malignancies, and 7 (3.8%) were neurogenic. In 4 patients (2.2%), the cause remained unclear. We identified ACF in 32 patients. The etiologic factors included previous long-term intubation in 22 patients (68.8%), short-term intubation in 3 patients (9.4%), Wegener's granulomatosis in 3 patients (9.4%), rheumatoid arthritis in 2 patients (6.3%), previous laryngeal surgery in 1 patient (3.1%), and caustic ingestion in 1 patient (3.1%). Additional second-site airway stenosis was found in 10 of the RLNP patients (5.4%) and in 15 of the ACF patients (46.9%). All RLNP patients had endoscopic surgery without temporary tracheotomy. Eighteen ACF patients required open surgery, and 4 were managed endoscopically but required temporary tracheotomy. The etiologic factors were significantly different for the two entities under study. Additional sites of stenosis were more frequent in ACF patients. Stenosis due to RLNP could be managed endoscopically without preliminary tracheotomy, while ACF frequently required open surgery and temporary tracheotomy.

Abstract
Derived from arytenoidectomy, different surgical techniques have been developed for widening the glottis in cases of bilateral vocal cord paralysis. Their anatomical bases were reinvestigated in plastinated serial sections of 25 adult human larynges. At the anterolateral surface of the arytenoid cartilage, blood vessels crossing the crista arcuata may cause bleeding complications. The arytenoid cartilage is related to three major histologic complexes which must be taken into account during surgery. The dense connective tissue complex consists of the cricoarytenoid ligament and the conus elasticus, which are connected ventrocaudally. The cricoarytenoid ligament and the vocal cord are separated by the cartilaginous inscription of the vocal process. The muscular complex consists of the transverse arytenoid muscle, which is the posterior wall of the glottis, and the thyroarytenoid muscle, which is intimately fixed to the conus elasticus near the arytenoid cartilage. The loose connective tissue complex is represented by the vestibular fold, containing adipose tissue, mucous glands, few collagenous fiber septa, and at its posterior end, a small cranial extension of the vocal cord. For glottic widening surgery, the arytenoid cartilage must be regarded as an integrated component of an extended fibro-cartilaginous framework supporting the laryngeal airway. Shrinking processes of the dense connective tissue elements may complicate surgical interventions. Iatrogenic lesions of the posterior glottis should be avoided to prevent the development of synechia or insufficient closure of the larynx during swallowing.

Abstract
Despite many operative procedures focused on vocal fold lateralization, none has achieved an acceptable level of dependability. Bilateral vocal fold abductor paralysis is treated by arytenoidectomy, cordotomy, suture lateralization, or partial cordectomy. Tracheotomy remains the gold standard for maximizing the airway and preserving phonatory function. We have developed a device that is minimally invasive, tunable, and reversible, with the potential for lateralization or medialization of the vocal process. The device consists of a polyethylene collar, a Vitallium cam, and a double-helix core for engaging soft tissue. It is introduced through a circular opening in the thyroid cartilage by a modified thyroplasty approach. Both the first and second iterations of this device have been evaluated for clinical effectiveness in 9 sheep by means of photographic and video documentation. Effectiveness in humans is currently being assessed. The results of the animal study permit us to have substantial optimism with respect to the clinical application of this device.

Abstract
Our objective was to assess the effectiveness of transoral laser cordectomy and laser arytenoidectomy and to compare the results with a view to respiratory and phonatory function and deglutition. Twenty-eight patients with bilateral vocal cord paralysis were included in a prospective study. Eighteen patients had cordectomy, and 10, arytenoidectomy. Lung function tests and voice analysis were performed preoperatively and postoperatively. Subclinical aspiration was determined by endoscopic evaluation of the larynx during deglutition. The results were compared to determine the relative effectiveness of both surgical methods. Flow volume spirograms documented equally improved flow rates in both groups. The final voice evaluation revealed that maximum phonation time, peak sound pressure levels, and frequency range were reduced in all 28 patients, but the phonatory results varied considerably in each group. Subclinical aspiration was noticed in 5 of 10 patients after arytenoidectomy, but in none of 18 patients after cordectomy. Four of 6 previously tracheostomized patients were decannulated within 2 weeks after surgery, while the other 22 patients had no perioperative tracheostomies. We conclude that transoral laser cordectomy and arytenoidectomy are equally effective and reliable in the management of the restricted airway. Phonatory outcome is not predictable with either surgical procedure. Cordectomy is easier and faster to perform, and subclinical aspiration is not encountered with this procedure.

Abstract
Using the mongrel dog as an animal model, we studied the effectiveness of botulinum toxin (Oculinum) to lateralize the true vocal cord. This experiment was undertaken in order to determine whether the toxin can improve the airway in subjects with bilateral abductor vocal cord paralysis. The toxin was injected into the cricothyroid muscle to block neuromuscular transmission at the motor end-plate. Paralysis of the cricothyroid muscle was achieved and documented by electromyography and videotaped endoscopy. Paralysis of the cricothyroid muscle decreases the tension of the true vocal cord and allows the cord to take a more lateral position. In this preliminary report, the literature is reviewed, the effect of and action of the toxin are discussed, and the results of the experimental protocol, establishment of dose-response curves, and techniques of injection are presented. Preliminary data suggest that there is an increase in the airway by lateralizing the true vocal cord with this biologic substance, and that this method may have many applications in clinical medicine for the otolaryngologist-head and neck surgeon.
