“…However, most of them are iatrogenic. The detailed harvesting methods are different in each study and reviewed by Truzzi et al [ 10 ]. The injection methods are also different for each study; transcutaneous injection and transoral injection, both by suspension laryngoscopy, are the main methods for autologous fat injection laryngoplasty.…”

“…Few studies have compared fat to other materials for sustained voice outcome improvement. However, some laryngologists considered fat injection laryngoplasty a permanent effect because of adipose stem cells contained in the autologous fat during its harvesting [ 10 ]. The quality of fat is affected by harvesting technology, characteristic differences of individual fat, and tissue reaction of autologous fat to the surrounding laryngeal tissues.…”

Background: Unilateral vocal palsy (UVFP) affects the voice and swallowing function and could be treated by various materials to achieve improved mucosal wave and better closure during phonation. Injection laryngoplasty is considered an exemplary method for these patients and could be injected as early as possible. We conducted a systematic review and meta-analysis for the subjective and objective outcomes of autologous fat injection laryngoplasty (AFIL) and assessed the effects for patients with UVFP. Methods: We searched studies from PubMed and EBSCO databases with PRISMA appraisal to search for articles about the effects of AFIL on UVFP. The published articles were reviewed according to our inclusion and exclusion criteria. The short- and long-term outcomes of perceptual, acoustic analysis, and quality of life were also analyzed by meta-analysis. Results: Eleven articles were reviewed, and seven studies were selected for meta-analysis. AFIL improves the perceptual outcome and some voice parameters in short-term and long-term results, i.e., jitter, shimmer, and maximal phonation time (MPT). It also significantly improved the voice handicap index (VHI) in the long term, suggesting an increase in quality of life. Conclusions: AFIL is considered a reliable treatment method for UVFP and could even last for over 12 months.

“…Generally, permanent augmentation should only be applied when spontaneous recovery of the recurrent laryngeal nerve paralyses can no longer be expected or persistent damage of the nerve due to previous diseases or surgeries is known. Autologous fat is biocompatible, cheap to gain, and non-toxic [24]. The disadvantage is the initial resorption rate that cannot be predicted.…”

Aktive und passive Bioimplantate bei Stimmlippenlähmung

ZusammenfassungStimmlippenlähmungen gehören zu den die Lebensqualität in besonderem Maße beeinträchtigenden Erkrankungen. Während einseitige Paresen zu Glottisschlussinsuffizienz und Heiserkeit führen, gefährden beidseitige Paresen die Atmung und schränken die körperliche Belastungsfähigkeit ein. Zur Therapie persistierender Paresen werden seit über 100 Jahren Bioimplantate eingesetzt. Das Spektrum reicht vom autologen Gewebetransfer über resorbierbare bzw. permanente Injektionsmaterialen bis hin zu Komposit-Thyreoplastikimplantaten und aktiven elektrischen Implantaten für die Neurostimulation des Larynx. Bei indikationsgerechtem Einsatz der Bioimplantate kann die Lebensqualität der betroffenen Patienten heute erheblich verbessert werden.

“…Der Volumenschwund variiert stark und ist abhängig von der Entnahmetechnik, wie z. B. der Größe der Liposuktionskanüle und der Höhe des aufgewendeten Unterdrucks.Eine systematische Literatursuche von 2017 zur IGP mittels Eigenfett ergab, dass stimmbezogene Daten hinsichtlich der zu bevorzugenden Entnahmetechnik und Ergebnisse fehlen[17]. Aufgrund der eingeschränkten Vorhersagbarkeit der Resorptionsquote können multiple Injektionen, z.…”
