Hyaluronic acid injection for medialization laryngoplasty is a safe procedure performed on patients with glottic incompetence. Laryngeal abscess formation as a complication of injection laryngoplasty is a very rare complication, and, as we know from the literature, there has been only one case of laryngeal abscess after injection laryngoplasty in a patient with a type-I laryngeal cleft. We document for the first time a laryngeal abscess resulting from hyaluronic acid injection laryngoplasty for unilateral vocal fold paralysis. Read More

Objectives: Neuromuscular control, glottal conformation, and aerodynamics are the major factors affecting voice performance. We aimed to characterize the degree to which voice improvements following office-based intracordal hyaluronate injection laryngoplasty (HIL) depend on changes in voice aerodynamics in patients with unilateral vocal fold paralysis (UVFP), by assessing the correlations between these parameters.

Design: Prospective case series. Read More

Tapia's syndrome is an infrequent complication of airway manipulation. It is usually due to an extra-cranial ipsilateral injury to the hypoglossal nerve and the recurrent laryngeal branch of the vagal nerve, which can happen after any surgery. It is usually characterized by unilateral paralysis of the muscle of the tongue and vocal cords although it can also occur bilaterally. Read More

Objectives:: Liuzijue Qigong (LQG), a kind of traditional Chinese health exercise (TCHE), is not only widely used to strengthen physical fitness and maintain psychological well-being in the elderly but has also been utilized to help improve respiratory function. As respiratory support is an important driving force for speech production, it is logical to postulate that the LQG training method with 6 monosyllabic speech sounds, xū, hē, hū, sī, chuī, and xī, can help individuals (1) experience a relaxing and natural state of speech production, (2) eliminate voice symptoms, and (3) improve their overall body function and mood. In the current study, we hypothesized that the LQG method with these 6 sounds can be effective in improving vocal function in subjects with unilateral vocal fold paralysis (UVFP) in comparison with a conventional voice therapy method.

Department of Otolaryngology-Head and Neck Surgery, Massachusetts Eye and Ear Infirmary, Boston, MA, USA.

Objectives: Unilateral vocal fold paralysis (UVFP) impairs communication and reduces academic performance and social interactions in children. Deciding between temporary, permanent, or potentially destructive surgical interventions can be challenging, as there currently exists no reliable means of predicting vocal fold recovery or assessing the presence of vocal fold atrophy. Regarding vocal fold atrophy, optical coherence tomography (OCT) has been shown to be an appealing non-invasive alternative for accessing vocal fold structures. Read More

Objectives/hypothesis: Unilateral vocal fold paralysis is a structural abnormality that often occurs secondary to dysfunction of the recurrent laryngeal nerve and typically presents as a breathy voice. Medialization laryngoplasty is a constellation of procedures that improves apposition of the vocal cords. Many patients, however, fail to experience sufficient improvement in vocal quality postoperatively despite apparent glottic closure on stroboscopy. Read More

Objective: Recent advances in preoperative imaging techniques and intraoperative parathyroid hormone (ioPTH) assays have made single-gland, minimally invasive parathyroidectomy (MIP) the preferred treatment option for most patients with primary hyperparathyroidism (pHPT). Despite this evolution, a recommendation for bilateral neck exploration (BNE) with four-gland dissection in all patients has recently been advocated by a parathyroid surgical group. The current study compares the long-term outcomes of MIP with those of conventional BNE with four-gland dissection in patients with pHPT. Read More

While the impact of injection laryngoplasty on voice outcomes in unilateral vocal fold immobility has been well characterized, there is a relative paucity of literature investigating its influence on swallow function and outcomes. We performed a retrospective chart review of patients presenting to an academic cancer center between January 2014 and January 2016 to evaluate the clinical impact of percutaneous injection laryngoplasty on reduction of aspiration risk, patient perception of swallowing, and recommended safe diet in patients with vocal fold immobility after head and neck and thoracic surgery. A consecutive sample of patients diagnosed with unilateral vocal fold immobility with patient- or clinician-identified abnormal swallow function who underwent bedside or in-office vocal fold injection was included in the study.

In this study, laryngeal flow fields are investigated and compared in normal larynx and models of larynx with unilateral vocal fold paralysis (UVFP). In paralytic models, three fixed initial glottal gaps are considered to understand the positive or probable negative impacts of surgical operation on unilaterally paralytic larynx, by which the paralyzed vocal fold is brought closer to the mid-plane. Various features of the flow fields have been discussed in detail including glottal gap width, glottal flow rate, glottal exit pressure pattern and glottal jet evolution. Read More

Background: Laryngeal re-innervation in paediatric unilateral vocal fold paralysis is a relatively new treatment option, of which there has been little reported experience in Europe.

Methods: In this European case report of a 13-year-old boy with dysphonia secondary to left-sided unilateral vocal fold paralysis after cardiac surgery, the patient underwent re-innervation using an ansa cervicalis to recurrent laryngeal nerve transfer, in combination with fat augmentation, after 12 years of nerve denervation. Perceptual analysis data, and acoustic and laryngoscopy recordings were acquired pre-operatively, and at one and two years post-operatively. Read More
