INTRODUCTION: Unilateral vocal fold paresis may significantly impair the vocal quality and laryngeal competence of a child. Relatively little literature relates to injection medialisation laryngoplasty (IML) in children and previous reports have involved small numbers of heterogenous cases. METHODS: A retrospective review was conducted of paediatric patients managed by our multidisciplinary specialist voice clinic undergoing IML for unilateral vocal fold paresis...

OBJECTIVE: To assess voice outcomes in patients undergoing vocal fold injection (VFI) augmentation laryngoplasty in a clinic-based setting. METHODS: A prospective study of patients with unilateral vocal cord palsy undergoing Radiesse(®) vocal cord augmentation. We used the ten-item voice handicap index (VHI-10) as a postal survey before and after the intervention. RESULTS: A total of 43 patients were referred to our ENT clinic from June 2011 to October 2014 with unilateral vocal cord palsy...

PURPOSE: To compare the inflammatory reaction caused by the injection of a sugarcane biopolymer (SCB) into the vocal fold of rabbits with that caused by calcium hydroxyapatite (CaH). METHODS: CaH (Radiesse(r)) and SCB gel were injected respectively into the right and left vocal cords of thirty rabbits. The rabbits were distributed into two equal groups and sacrificed at three and twelve weeks after injection. We then evaluated the intensity of the inflammatory reaction, plus levels of neovascularization, fibrogenesis and inflammatory changes in the vocal mucosa...

OBJECTIVES/HYPOTHESIS: To evaluate the short-term voice outcomes of vocal fold augmentation using fat compared to calcium hydroxylapatite product Radiesse Voice (Merz Aesthetics). STUDY DESIGN: Retrospective study design. METHODS: Sixty-six consecutive patients with vocal fold insufficiency were recruited, including the final 33 patients treated with fat and all 33 patients treated with calcium hydroxylapatite product. Before April 2011, fat augmentation was the standard treatment; from April 2011, only calcium hydroxylapatite product was used...

OBJECTIVES/HYPOTHESIS: This study examined changes in voluntary cough airflow measures immediately following in-office injection of Radiesse in patients diagnosed with glottic insufficiency. Due to significant comorbidities, these patients were poor candidates for medialization under general anesthesia. Each patient presented with dysphonia and dysphagia and ineffective voluntary cough, resulting in a poor clearing of secretions and a presence of ingested fluids on examination. STUDY DESIGN: Prospective cohort and case series study...

OBJECTIVES/HYPOTHESIS: The purposes of this preclinical study were to investigate histologic and rheologic outcomes of Microendoscopy of Reinke's space (MERS)-guided minithyrotomy and to assess its instrumentation. STUDY DESIGN: Human cadaveric and in vivo animal study. METHODS: Three human cadaveric larynges were treated with MERS-guided placement of Radiesse VoiceGel and immediately evaluated histologically for biomaterial location. In the second part of this investigation, two scarred porcine larynges were treated with MERS-guided placement of HyStem-VF and rheologically evaluated 6 weeks later...

OBJECTIVES/HYPOTHESIS: The purpose of this study was to explore a novel strategy to restore vocal gap by using polycaprolactone (PCL) spheres with thermosensitive Pluronic F127 in a paralyzed rabbit vocal fold. STUDY DESIGN: In vivo study using a rabbit model. METHODS: The PCL spheres were fabricated by an isolated particle-melting method. The PCL spheres/Pluronic F127 gel mixture was prepared by a simple mixture of PCL and Pluronic F127 solution...

COMPARATIVE STUDY

CONCLUSION: The choice of technique will depend on the glottic gap observed by stroboscopy, the alteration of the Voice Handicap Index (VHI) and the recorded values of harmonics-to-noise ratio (HNR), jitter and shimmer, and the general health, age and underlying pathology. There are statistically significant differences between the values of VHI, shimmer and jitter in favour of those cases operated on within 6 months of diagnosis. Alternatives are discussed. OBJECTIVES: This study analysed and compared the functional, morphological and acoustic results, after surgery, through the techniques of medialization thyroplasty and infiltration of biomaterials to correct incomplete closure of the glottis...

REVIEW
Patricio F Jacovella
Radiesse (Bioform Inc, USA) is a sterile, latex-free, non-pyrogenic, semi-solid, cohesive subdermal, injectable implant, whose principal component is synthetic calcium hydroxylapatite, a biocompatible material with over 20 years of use in medicine. The semi-solid nature of the product is created by suspending calcium hydroxylapatite microspheres of 25-45 microns diameter in a gel carrier of carboxymethylcellulose. The product has FDA approval for esthetic facial augmentation in the US. Such approval includes the long-lasting correction of moderate to severe facial wrinkles and folds and the treatment of facial fat loss due to immunodeficiency virus infection...

OBJECTIVES: The purpose of this study was to measure and compare biomechanical properties of commonly used vocal fold injectates Cymetra, Radiesse, Restylane, Hylaform, and one investigational injectate, Carbylan-GSX 5%, to determine suitability for mucosal injection. STUDY DESIGN: Rheologic investigation. METHODS: Oscillatory shear stress was applied to five samples of each injectate using a parallel plate controlled stress rheometer. Shear stress, shear strain, and strain rate associated with the oscillatory shear deformation were computed from the prescribed torque and measured angular velocity; viscoelastic data were obtained on the basis of these functions...
