[Surgery of the Larynx - Part 2b: Transcervical Surgical Therapy of Malignant Lesions]. / Chirurgie des Larynx ­ Teil 2b: Transzervikale chirurgische Therapie maligner Läsionen.

Transoral endoscopic laryngeal surgery (TEC) is typically used as a cervical tissue-sparing and function-preserving surgical procedure. Transoral robotic surgery (TORS) in particular has been pushing the boundaries towards transoral resection in recent years. Nevertheless, there are still limitations to this approach. Transcervical surgery is then the therapy of choice. It is used in case of insufficient visibility of the entire larynx and especially the tumor-bearing region, cartilage infiltration, a lack of mobility of both arytenoid cartilages or a lack of patient compliance. Even with the transcervical approach, from an oncological point of view, the procedure must be as radical as necessary on the one hand and as function-preserving as possible on the other. In case of a transcervical appraoch, however, additional requirements, side effects and consequences must be considered during planning, implementation and follow-up treatment. In addition to our previous publications, this article is intended to provide an overview of transcervical surgery for malignancies of the larynx.

[Laryngeal Surgery - Malignant Lesions]. / Chirurgie des Larynx: Maligne Läsionen.

This article is intended to give an overview of the surgery for laryngeal malignancies and the current state of transoral endoscopic laryngeal surgery. The current therapy concepts in transoral endoscopic laryngeal surgery are presented in combination with the various possibilities of reconstruction. The adequate oncological treatment under functional aspects described plays the decisive role here: treatment goals beyond the cure of the tumor disease are the functional maintenance of the larynx with simultaneous preservation of the voice. In general, the diagnosis and treatment of (pre-) cancerous lesions of the laryngeal mucosa is demanding and requires a great deal of experience of the attending laryngologist. Updated classification systems support level-based categorization. In transoral endoscopic laryngeal surgery, resection using cold instruments and the CO2 laser are currently among the traditional methods, although newer methods such as the angiolytic laser can be used to ablate these lesions. Transoral endoscopic laryngeal surgery is a highly endoscopic-microscopic procedure in (pre-) cancerous lesions, which may presumably continue to evolve from the microlaryngoscopic approach over the next few years due to the introduction of new instruments and high-resolution imaging techniques. Robot-assisted surgery has also found its way into the transoral endoscopic treatment of laryngeal carcinoma. Only in the next few years, however, will it become clear to what extent this technique can supplement, replace or clarify surgical methods, since the individualized surgical strategy currently has a priority position for every single patient.

Population-based cross-sectional study to assess newborn hearing screening program in central Germany.

OBJECTIVES: Early diagnosis of congenital hearing loss is fundamental to minimize the negative consequences on the speech development. To lower the age at diagnosis and at intervention in hearing impaired children, not only universal newborn hearing screening (NHS) but also tracking is considered essential. The aim of the study was to evaluate the first six years after implementation of the population based newborn hearing screening program in Saxony-Anhalt, one German Federal State. METHODS: The cross-sectional cohort study consisted of three cohort samples. Overall 102,301 infants born between January 2010 and December 2015 were included. NHS protocol was developed as dual target group protocol with two sub-protocols. The screening technique included Transient Evoked Otoacoustic Emissions (TEOAE) and Automated Auditory Brainstem Response (AABR) test. Newborns were assigned to the sub-protocols according to their audiological risk factors. Additionally, to evaluate the quality of NHS and tracking (false-negative screening) we were analysing data from a cohort of hearing impaired children diagnosed up to the age of three years. We calculated quality indicators and compared them with international guidelines. RESULTS: 101,102 (98.8%) infants were screened. The prevalence of bilateral neonatal hearing loss was 2.32 per 1000 newborns. The median age was two days at first screening, three month at diagnostic testing, and four month at intervention onset. 2.6% infants were lost to follow-up. 56.3% had a final diagnosis of bilateral sensorineural hearing loss. The sensitivity of 0.85 (KI 95%: 0.76­0.91) and a specificity of 0.84 (KI 95%: 0.84­0.85) was calculated for the NHS program. CONCLUSIONS: The analysis of benchmarks and outcomes of NHS demonstrated that the program reaches its main goal to identify the hearing impaired newborns in a timely manner.

Automatic Evaluation of Voice Quality Using Text-Based Laryngograph Measurements and Prosodic Analysis.

Due to low intra- and interrater reliability, perceptual voice evaluation should be supported by objective, automatic methods. In this study, text-based, computer-aided prosodic analysis and measurements of connected speech were combined in order to model perceptual evaluation of the German Roughness-Breathiness-Hoarseness (RBH) scheme. 58 connected speech samples (43 women and 15 men; 48.7 ± 17.8 years) containing the German version of the text "The North Wind and the Sun" were evaluated perceptually by 19 speech and voice therapy students according to the RBH scale. For the human-machine correlation, Support Vector Regression with measurements of the vocal fold cycle irregularities (CFx) and the closed phases of vocal fold vibration (CQx) of the Laryngograph and 33 features from a prosodic analysis module were used to model the listeners' ratings. The best human-machine results for roughness were obtained from a combination of six prosodic features and CFx (r = 0.71, ρ = 0.57). These correlations were approximately the same as the interrater agreement among human raters (r = 0.65, ρ = 0.61). CQx was one of the substantial features of the hoarseness model. For hoarseness and breathiness, the human-machine agreement was substantially lower. Nevertheless, the automatic analysis method can serve as the basis for a meaningful objective support for perceptual analysis.

Position paper of the German Society of Oto-Rhino-Laryngology, Head and Neck Surgery and the German Society of Phoniatrics and Pediatric Audiology - Current state of clinical and endoscopic diagnostics, evaluation, and therapy of swallowing disorders in children.

Swallowing disorders are frequent. The main concern is mortality due to aspiration-induced pneumonia and malnutrition. In addition, quality of life is severely affected. The demographic trend indicates an increase of dysphagia in the future. Neurodegenerative diseases, tumors of the digestive tract, and sequelae of tumor treatment in the head and neck region are the main pathologic entities. Predominantly ENT physicians and phoniatricians are asked for diagnostics and therapy, and will coordinate the interdisciplinary treatment according to the endoscopic findings. A differentiated approach in history, diagnostics, and symptom-oriented treatment is necessary for these mostly complex disorders. Integration of non-medical staff such as speech therapists, physiotherapists, and occupational therapists in planning and executing an effective therapy expands and completes the patient-oriented care. Conservative treatment by these therapists is an important pillar in the treatment. Parts of the specific diagnostics can be taken over in close cooperation. In particular, an interdisciplinary cooperation with the staff of intensive care medicine is essential. The diagnostic procedures of specific endoscopy as described in this position paper are part of the primary and fundamental tasks of ENT specialists and phoniatrists. Endoscopy is a medical service that is basically not delegable. Consequently, substitution of the physician is excluded.

A boy with mild mental retardation, mild sensorineural hearing loss and mild facial dysmorphism caused by a 19p13.2 deletion: a case report and review of the literature.

The investigation of patients with congenital anomalies and/or intellectual disability with modern genetic methods allows the recognition of an increasing number of cases with these chromosomal rearrangements. Here, we present a mildly mentally retarded boy with mild facial dysmorphism, language development delay, mild sensorineural hearing loss due to a deletion of 1,14 Mb on chromosome 19p 13.2. The deletion was de novo and familial history negative for this disorder. To our knowledge this is the first description of a patient with symptoms mentioned above associated with a 19p13.2-p13.2 deletion.

Bamboo nodes associated with mixed connective tissue disease as a cause of hoarseness.

Vocal fold lesions related to autoimmune diseases are rheumatoid nodules and, to a lesser extent, bamboo nodes. Mostly transverse, they are located in the middle third of the vocal cord and exhibit a yellowish appearance. The characteristic shape of these lesions led to their name. These vocal fold deposits may interfere with the normal vibratory cycle during phonation and thus may be an unusual cause of hoarseness. We present a 43-year-old woman with known mixed connective tissue disease and a dysphonia. Laryngostroboscopy showed bamboo nodes as described above. We applied several laryngeal injections of cortisone as described previously in the literature. Since this treatment did not lead to a sufficient voice improvement, we attempted to surgically remove the deposits. After the surgery, the voice improved considerably. In all patients with rheumatic diseases who suffer from a rough, breathy, or unstable voice, a laryngostroboscopic examination should be done. If, however, a bamboo node lesion of the vocal folds is found by the laryngologists, an associated autoimmune disorder must be assumed, and adequate diagnostic procedures have to be initiated. Local laryngeal injections (1-3 times) with steroids should be the first line of therapy. In unsuccessful cases, subsequent surgery can be a useful treatment of bamboo nodes to stabilize and improve voice quality.
