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.

Introduction: Unilateral vocal fold paralysis (UVFP) without an identifiable cause is termed idiopathic unilateral vocal fold paralysis (IUVFP). Some authors have postulated that select cases of IUVFP have a viral etiology, but the causality has not been established. We set out to review institutional cases of IUVFP and determine if there is a correlation between upper respiratory infection symptoms and presentation of IUVFP. Read More

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: Paralysis of one vocal fold leads to glottal gap and vocal fold insufficiency that has significant impact upon a patient's quality of life. Fillers have been tested to perform intracordal injections, but they do not provide perdurable results. Early data suggest that enriching fat grafts with adipose-derived regenerative cells (ADRCs) promote angiogenesis and modulate the immune response, improving graft survival. Read More

University of Kentucky, Lexington.

Purpose: The purpose of this study is to quantify the interactions of the 3 vocalization subsystems of respiration, phonation, and resonance before, during, and after a perturbation to the larynx (temporarily induced unilateral vocal fold paralysis) in 10 vocally healthy participants. Using dynamic systems theory as a guide, we hypothesized that data groupings would emerge revealing context-dependent patterns in the relationships of variables representing the 3 vocalization subsystems. We also hypothesized that group data would mask important individual variability important to understanding the relationships among the vocalization subsystems. Read More

Background: Medialisation thyroplasty is considered the 'gold standard' treatment for unilateral vocal fold paralysis, enabling improvement of voice and swallowing function, and preventing life-threatening aspiration events. The most commonly used laryngeal implants induce some degree of local tissue inflammatory response, and carry the risk of immediate or delayed implant extrusion.

Background: Extubation is a more challenging medical practice than intubation, and countermeasures against it are similar to those described in the Difficult Intubation Guidelines, but problems cannot be overcome by completely the same methods. We predicted difficult extubation in a pediatric patient with left recurrent laryngeal nerve paralysis and devised an extubation method.

Case Presentation: The patient was a 2-year-and-8-month-old boy scheduled for cleft palate repair. Read More

Objectives: Bilateral vocal fold paralysis (VFP) is a severe complication after laryngotracheal (LT) surgery. The reduced glottic opening leads to significant respiratory distress immediately after the operation and requires the placement of a tracheostomy in most cases. Patients with a pre-existing unilateral VFP or expected recurrent nerve resection are at the highest risk for glottic failure. Read More

There is a growing need for evaluation tools allowing the quantification of the outcome after voice surgeries. Since the end of the 1990s, multiple unfruitful attempts have been made to reach a consensus, including the Dejonckere protocol for the European Laryngological Society in 2001.
