“…Patients receiving a repeated procedure saw a signifi cantly smaller improvement in VHI-10 than those where it was the primary treatment (mean reduction: 9.8 vs 15.5, p = .018). Analysis of MPT found a signifi cant correlation between the quantity of injection material used and the degree of improvement observed (rho = 0.355, p = .004) (7).…”

The aim of the work was to evaluate the voice quality of 10 adult patients after thyroplasty type I using a silicone block. Preoperatively patients suffered from unilateral vocal fold paralysis. MATERIAL AND METHODS: We evaluated selected preoperative and postoperative patient fi ndings (RBH according to Wendler classifi cation, videolaryngostroboscopy and maximum phonation time MPT). The evaluation was performed by a phoniatrician and clinical speech therapist, using patient medical records and the Lingwaves and Glottis Analysis Tools (GAT) programs. RESULTS: Preoperatively we identifi ed R1B1H1-R3B3H3, postoperatively R0B0H0-R3B3H2. In six cases the paralysed vocal cord was preoperatively in a paramedian position, twice in intermediate position and twice in a lateral position. In the case of 6 patients presbyphonic changes were present. Motility of the healthy vocal cord was within the norm. Postoperatively, the paretic vocal cord was medialised. We assessed the MPT value: preoperatively 3-10 seconds, postoperatively 9-17 seconds. Postoperatively we measured jitter (%), shimmer (%) and closing quotient values. In comparison with healthy subjects (Inwald et al. 2011), jitter and shimmer values were higher and closing quotient values after thyroplasty type I close to normal values (Tab.1). CONCLUSIONS: The postoperative voice quality was signifi cantly better in comparison with the preoperative state; though, it never achieved the parameters of a normal voice. We confi rmed the signifi cant contribution of TPL I for the patients´ quality of life through partial rehabilitation of their voices. Text in PDF www.elis.sk.

“…With regard to vocal cord medialisation the most popular options are injection laryngoplasty (IL) and type I thyroplasty 6 (Using Sialastic or Titanium) or a combination of both techniques. With regard to injection laryngoplasty some studies have also shown a corelation between and quality and quantity of material used with improvement of maximum phonation time (MPT) 7 .…”

Vocal cord medialization and Sulcus-vocalis surgical management

Complete or partial paralysis of one or both vocal cords can significantly affect a patients phonation ability as well as risk aspiration. Sulcus vocalis is a condition where there is a groove running parallel to the edge of the vocal cord extending from the anterior commissure to the anterior edge of the vocal process of the arytenoid cartilage. Injection laryngoplasty (IL) is a minimally invasive technique which can successfully deal with both of the above-mentioned conditions directly as well as indirectly with only a slight modification in technique using autologous ‘insulinated fat’. Additionally, when treating sulcus vocalis, cold steel dissection of the sulcus through a small parallel incision was preferred without subsequent mucosal suturing. Using 2 surgeons (4 hand technique) improves precision of instrumentation when using a high-definition rigid bronchoscope through a suspension laryngoscopy setup. This is needed especially for precision injection of long-term injectables in injection laryngoplasty.

Purpose Volume injected for glottic insufficiency is paramount in achieving desired outcome. Factors that determine the required volume have not been thoroughly investigated and may correlate with outcome. The first objective of this investigation was to evaluate the association between injectable volume and various parameters, including lifestyle characteristics, pre-procedural factors, and voice measures, while the second aim assessed the correlation of volume to clinical outcomes in patients who underwent injection laryngoplasty. Methods For the first objective, a one-way ANOVA and univariate linear regression were used to analyze data from 124 patients (injected material, pre-operative diagnosis, previous voice therapy, age etc.). One-sample t-tests and Pearson correlational coefficients were employed for statistical analysis of aim 2 in a subgroup of 28 patients that had pre- and post-injection voice evaluations (e.g., acoustic and aerodynamic analysis, perceptual assessment, questionnaires). Results Average injection volume was 0.39 ± 0.062 mL (range: 0.1–1.6mL). No pre-procedural or lifestyle factor significantly affected injection volume (p > 0.05). There was no relationship between pre-procedural voice outcomes and injection volume (p > 0.05). Of the factors that were significantly improved post-injection laryngoplasty (GFI, VHI, and GRBAS), there were no significant correlations between the magnitude of improvement in these measures and injection volume (p > 0.05). Conclusion Injection volume does not appear to be affected by pre-procedural or lifestyle factors. In addition, injection volume does not significantly impact clinical outcomes assessed through voice analysis or patient-reported questionnaires. Our results underscore the complexity of factors at play in injection laryngoplasty for glottic insufficiency.
