“…A series of modifications were related to the traction direction of the thread to a fixation point that is located even more anterior-medio-caudally below the insertion of the vocal fold at the inferior edge of the thyroid cartilage 76 . Other modifications concerned the position and size of the additional cartilage window at the posterior edge of the thyroid 77 and less invasive approaches to position the thread, e. g., the sling or string pull technique described by Hess 78 79 . AA is technically more complex, and the combination of ML with AA is associated with a clearly higher risk of hospital re-admission within 30 days 80 .…”

“…Eine Reihe von Modifikationen betreffen die Zugrichtung des Fadens hin zu einer noch weiter anterior-medio-kaudalen Fixierung unterhalb der Insertion der Stimmlippe am Schildknorpelunterrand 76 , die Lage und Größe des zusätzlichen Knorpelfenster am Schildknorpelhinterrand 77 und weniger invasive Zugänge zur Platzierung des Zugfadens, z. B. mit der von Hess angegebenen Sling oder String pull Technik 78 79 . Die AA ist technisch schwieriger und die Kombination der ML mit einer AA ist mit einem deutlich höheren Risiko einer Krankenhauswiederaufnahme innerhalb von 30 Tagen behaftet 80 .…”

“…Initially, the cartilage of the thyroplasty window was further used with its perichondrium as stamp; and foreign material was applied for locking and later also for V-shaped adaptation of the medialization effect under auditive control in surgeries performed in local anesthesia [52,53]. Most widely used are medical silicone blocks that are individually cut during surgery [54]. The advantage consists of the individual shaping with consideration of the sex-specific thyroid angle [55], the length of the thyroid ala, and the malposition of the paralyzed vocal fold that shall be corrected (see ▶Fig.…”

“…Dabei wurde zunächst weiter der Knorpel des Thyreoplastikfensters mit seinem Perichondrium als Stempel verwendet und Fremdmaterial anfangs zur Verriegelung und später keilförmig auch zur Anpassung der Medialisationswirkung unter auditiver Kontrolle, bei in Lokalanästhesie durchgeführter Operation, verwendet [52,53]. Die größte Verbreitung als Biomaterial haben bis heute Blöcke aus medizinischem Silikon, die vom Chirurgen während der Operation individuell zugeschnitten werden, gefunden [54]. Der Vorteil liegt in der individuellen Formung unter Berücksichtigung des geschlechtsspezifischen Schildknorpelwinkels [55], der Länge des Schildknorpelflügels und der zu korrigierenden Fehlstellung der gelähmten Stimmlippe (siehe ▶Abb.…”

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.

“…Phonatory shape and stiffness are also targeted by many phonosurgical interventions. These include adduction procedures, such as injection laryngoplasty, medialization thyroplasty, and arytenoid adduction, 1 and length-changing procedures such as thyroplasty types 3-4, 2 and glottoplasty. 3 Current interventions use a superior endoscopic view to assess the vocal fold antero-posterior length and the degree of adduction.…”

Control of Pre‐phonatory Glottal Shape by Intrinsic Laryngeal Muscles

et al. 2022

Objectives Surgical manipulations to treat glottic insufficiency aim to restore the physiologic pre‐phonatory glottal shape. However, the physiologic pre‐phonatory glottal shape as a function of interactions between all intrinsic laryngeal muscles (ILMs) has not been described. Vocal fold posture and medial surface shape were investigated across concurrent activation and interactions of thyroarytenoid (TA), cricothyroid (CT), and lateral cricoarytenoid/interarytenoid (LCA/IA) muscles. Study Design In vivo canine hemilarynx model. Methods The ILMs were stimulated across combinations of four graded levels each from low‐to‐high activation. A total of 64 distinct medial surface postures (4 TA × 4 CT × 4 LCA/IA levels) were captured using high‐speed video. Using a custom 3D interpolation algorithm, the medial surface shape was reconstructed. Results Combined activation of ILMs yielded a range of unique pre‐phonatory postures. Both LCA/IA and TA activation adducted the vocal fold but with greater contribution from TA. The transition from a convergent to a rectangular glottal shape was primarily mediated by TA muscle activation but LCA/IA and TA together resulted in a smooth rectangular glottis compared to TA alone, which caused rectangular glottis with inferomedial bulging. CT activation resulted in a lengthened but slightly abducted glottis. Conclusions TA was primarily responsible for the rectangular shape of the adducted glottis with synergistic contribution from the LCA/IA. CT contributed minimally to vocal fold medial shape but elongated the glottis. These findings further refine laryngeal posture goals in surgical correction of glottic insufficiency.

The laryngeal framework surgery (LFS) is an operation to correct the position and tension of the vocal cords by changing the laryngeal cartilage and muscles. LFS such as type 1 thyroplasty, arytenoid adduction, and arytenopexy is performed to improve the voice of patients with unilateral vocal cord paralysis. It is known that the voice improvement effect of LFS in patients with unilateral vocal cord paralysis is excellent and lasts for a long time. LFS can also be operated under local anesthesia. Complications are not common, however, severe complications like airway obstruction could occur after the operation. Recently, several other attempts to modify the traditional surgical method have been reported. This review is intended to be helpful in understanding the characteristics and changes in laryngeal framework surgery.
