[Laryngeal framework surgery].

Laryngeal framework surgery is an umbrella term for all phonosurgical procedures by which the cartilaginous structure of the larynx and thereby the position and tension of the vocal folds are changed. The aim is to improve the voice. By far the best known and most frequently performed operation is thyroplasty type 1 according to Isshiki, also known as medialization thyroplasty, which is indicated for treatment of glottic insufficiency.

[Photoangiolytic Lasers in Laryngology].

With photoangiolytic lasers like KTP (Potassium-Titanyl-Phosphate, 532 nm) lasers or the new "blue" laser (445 nm), even the smallest vessels and capillaries within the vocal fold can be treated without destroying the covering epithelium. This enables effective treatment of benign and malignant sub- and intraepithelial lesions of the vocal folds such as papilloma, edema, polyps, leukoplakia, dysplasia and capillary vessels while preserving the vibratory properties of the different layers of the lamina propria. Because photoangiolytic laser light can be routed through tiny glass fibers, office-based surgery with channelled flexible endoscopes are feasible as well as phonomicrosurgical operations under general anesthesia.

Dipping and rotating: two maneuvers to achieve maximum magnification during indirect transnasal laryngoscopy.

Background: Since many years, office-based flexible transnasal laryngoscopy is a common routine procedure. The development of new technical equipment such as high-definition cameras and flexible tip-chip endoscopes nowadays allows for much more precise examination than a few years ago. In contrast to rigid laryngoscopy, it is possible to move the tip of the endoscope close to the vocal folds and to other structures of interest.

New 445 nm blue laser for laryngeal surgery combines photoangiolytic and cutting properties.

Background: Photoangiolytic lasers have broadened the surgical armamentarium for many phonosurgical interventions. However, the pulse dye laser and potassium titanyl phosphate (KTP) laser have technical drawbacks and a smaller spectrum of indications.

Methods And Results: The new 445 nm wavelength laser, the so-called 'blue laser', proves to show tissue effects comparable to the KTP laser and is also capable of treating subepithelial vessels due to its photoangiolytic properties, it can coagulate and carbonize at higher energy levels, and can be used via glass fibers in non-contact and contact mode for in-office procedures.

Narrow Band Imaging Enhances the Detection Rate of Penetration and Aspiration in FEES.

Narrow band imaging (NBI) is widely used in gastrointestinal, laryngeal, and urological endoscopy. Its original purpose was to visualize vessels and epithelial irregularities. Based on our observation that adding NBI to common white light (WL) improves the contrast of the test bolus in fiberoptic endoscopic evaluation of swallowing (FEES), we now investigated the potential value of NBI in swallowing disorders.

Laryngeal framework surgery: current strategies.

Purpose Of Review: Laryngeal framework surgery (LFS) is an indispensable surgical approach for the treatment of voice problems. The purpose of this review is to single out some relevant articles published on the topic of LFS from 2015 to mid-2016. Articles referring to injection laryngoplasty (augmentation) are entirely left aside.

Office-based laryngoscopic observations of recurrent laryngeal nerve paresis and paralysis.

Objectives: To evaluate the endoscopic criteria of recurrent laryngeal nerve disorders, we performed a retrospective evaluation of videolaryngoscopic recordings from 50 patients with recurrent laryngeal nerve disorders.

Methods: The videolaryngoscopic examination was performed with rigid and flexible endoscopes. The range of motion of three laryngeal structures was assessed: the vocal ligament, the vocal process, and the arytenoid "hump" (mainly the corniculate region).
