Objectives/hypothesis: Given the complex pathology underlying unilateral vocal fold paralysis (UVFP), there has been limited systematic exploration of curative treatments in humans. Central to the investigation of experimental therapies includes establishing a reliable and analogous large animal model. The study goal was to create a standardized porcine model of UVFP by establishing characteristic pathophysiology and functional outcomes.

Objectives/hypothesis: Assess the impact of the infraglottal medialization technique on acoustics and the vertical stiffness gradient of the vocal fold using excised canine larynges.
Methods: Seven ex vivo canine larynges were tested in three states: 1) no implant, 2) medialized using a glottal implant, and 3) medialized fold using an infraglottal implant. Outcome measures were vocal efficiency and stiffness of the fold.

Purpose: To search, evaluate, and summarize the relevant evidence of voice rehabilitation training in adults with unilateral vocal fold paralysis (UVFP).
Methods: Using the '6S' model, the database of UpToDate, BMJ Best Practice, domestic and foreign guidelines, and voice rehabilitation training for adults with UVFP were systematically searched. The search includes clinical decisions, guidelines, systematic reviews, randomized controlled trials, and expert consensus.
Delayed complications of arytenoid adduction and medialization laryngoplasty are rarely reported in the literature. Clinicians should be aware that performing an AA alongside an ML may seed oral cavity bacteria into the paralaryngeal space. This may result in delayed infection-especially in immunocompromised patients-necessitating implant removal and antibiotics.

Objective: Unilateral vocal fold paralysis (UVFP) following open thoracic aortic surgery increases pulmonary complications and hospital stays. An intervention protocol with early injection laryngoplasty (IL) and swallowing maneuvers was developed for acute UVFP following thoracic aortic surgery. This study aimed to compare the incidence of complications and length of medical care between the non-VFP and the IL-UVFP group managed under this protocol.

Objective: Vocal fold immobility (VFI) is a cause of significant morbidity and mortality in the paediatric population. Laryngoscopy is the current first-line investigation for patients with suspected VFI. Laryngeal ultrasound (LUS) has recently emerged as an alternative method of identifying VFI.

Objective: The aim of this study is to report on experience acquired during the laryngeal electrophysiological assessment with Co-MEP and L-EMG in pediatric patients with acquired, congenital, and syndromic vocal fold paralysis (VFP), and correlate our findings with patients' characteristics, their comorbidities, and VFP etiology.
Methods: Pediatric patients with suspected or previously diagnosed unilateral or bilateral VFP underwent electrophysiological records under general anesthesia; corticobulbar motor-evoked potentials (Co-MEPs) and laryngeal electromyography (L-EMG) of thyroarytenoid (TA) and posterior cricoarytenoid (PCA) muscles were recorded.
Results: Statistical analysis revealed a statistically significant correlation between early gestational age at childbirth and TA muscle intensity (p = 0.
Although laryngeal high-speed videoendoscopy (HSV) is crucial for studying vocal fold vibrations, its translation to clinical practice has been hindered by the large volume of data it produces and the difficulty in interpreting current analysis methods. Although image processing techniques have been developed to map spatial-temporal data into two-dimensional representations, they alter the geometrical construction of the glottis and do not provide standard quantitative features, thus challenging clinical interpretation. In response, we propose a new visualization and analysis framework for assessing the dynamics of vocal folds based on the empirical distribution of the glottal edge using HSV.

Background: Unilateral vocal fold pseudocysts have been hypothesized to result from vocal fold paresis, but no explanation has been proposed for bilateral lesions. This study compares patients with unilateral to those with bilateral pseudocysts for insights into pathogenesis.
Methods: Adults with unilateral and bilateral pseudocysts evaluated between 2018 and 2023 were retrospectively studied.

Objectives: Injection laryngoplasty (IL) has been widely used as an initial treatment option for unilateral vocal fold paralysis (UVFP). An additional (second) IL is considered a salvage treatment for unsatisfactory outcomes of initial IL resulting from inadequate injection or early resorption of the injection material. This study aims to evaluate the efficacy of additional IL, distinguishing between "salvage" (within 4 months) and "repeated" injections (beyond 4 months), and to analyze prognostic factors for successful outcomes.

Office-based laryngology procedures evolved in the recent years with all the technology advances and have gained popularity among laryngologists. The indications enlarged, making it a valid surgical option for almost all voice disorders. This emerging technique raise the question of the place left for traditional phonosurgeries in the operating room under general anesthesia.

Many voice disorders are linked to imbalanced muscle activity and known to exhibit asymmetric vocal fold vibration. However, the relation between imbalanced muscle activation and asymmetric vocal fold vibration is not well understood. This study introduces an asymmetric triangular body-cover model of the vocal folds, controlled by the activation of bilateral intrinsic laryngeal muscles, to investigate the effects of muscle imbalance on vocal fold oscillation.

Unilateral vocal fold paralysis (UVFP) has a known impact on patients' quality of life. One of the potentially affected domains that has not been studied yet is emotional prosody. To produce and transmit an efficient emotional prosody, several vocal parameters are modulated by the speaker, principally the fundamental frequency, the speech rate, and the voice intensity.

Objectives: Unilateral vocal fold paralysis (UVFP) can be idiopathic or a result of surgery, cancer, or neurological disease. The most common presentation is dysphonia, which causes problems with communication, and can lead to anxiety and depression. Injection laryngoplasty (IL) is a current means of treatment, but there have been few studies to determine the optimal material to use.

Background: Unilateral vocal fold paralysis (UVFP), characterized by immobility of one vocal fold, results from injuries of recurrent laryngeal nerves. Voice therapy is a conservative intervention aiming to address these symptoms, but standard protocols are lacking. In this study, we provided an updated review of voice therapy for UVFP over the past 3 years and analyzed the effect of voice therapy from the perspective of voice assessment recommended by the guidelines of the European Laryngological Society and the Union of the European Phoniatricians in 2023.

Objective: Current laryngeal injection models rely on the transoral route and are suboptimal due to limited view, narrowed working space, and the need to sacrifice animals for investigation of the injectables. In the present study, a novel surgical model for laryngeal intervention therapy utilizing an ultra-high frequency ultrasound imaging system was proposed. Based on this system, we developed a systemic evaluation approach, from guidance of the injection process, documentation of the injection site of the material, to in vivo longitudinal follow-up on the augmentation and medialization effect by analyzing the ultrasonography data.
