AIM Biofilm formation on voice prostheses, which are used for voice rehabilitation in laryngectomized patients, is a main cause of device failure. The aim of this study was to assess whether the presence of periodontal pathogens in the biofilm on voice prostheses is related to that in the oral cavity and associated with the periodontal status of the(More)
Laryngeal high-speed videos are a state of the art method to investigate vocal fold vibration but the vast amount of data produced prevents it from being used in clinical applications. Segmentation of the glottal gap is important for excluding irrelevant data from video frames for subsequent analysis. We present a novel, fully automatic segmen-tation method(More)
Verbal communication plays an important role in our economy. Laryngeal high-speed videos have emerged as a state of the art method to investigate vocal fold vibrations in the context of voice disorders affecting verbal communication. Segmentation of the glottis from these videos is required to analyze vocal fold vibrations. The vast amount of data produced(More)
Auditory voice quality judgements are used intensively for the clinical assessment of pathological voice. Voice quality concepts are fuzzily defined and poorly standardized however, which hinders scientific and clinical communication. The described database documents a wide variety of pathologies and is used to investigate auditory voice quality concepts(More)
OBJECTIVES The management of paediatric airway stenosis is complex, and requires a dedicated team, consisting of thoracic surgeons, phoniatricians, logopaedics, paediatricians and anaesthetists. The majority of paediatric laryngotracheal stenosis is a sequela of prematurity and prolonged post-partal intubation/tracheostomy. Surgical correction is often(More)
OBJECTIVES Repair of laryngotracheal stenosis with pronounced side-to-side narrowing and involvement of the glottis is challenging and usually requires laryngotracheal reconstruction with rib cartilage interpositions. This technique, as first described by Couraud, needs prolonged postoperative stabilization with Montgomery T-tubes, imposing significant(More)
OBJECTIVES Diplophonia is an often misinterpreted symptom of disordered voice, and needs objectification. An audio signal processing algorithm for the detection of diplophonia is proposed. Diplophonia is produced by two distinct oscillators, which yield a profound physiological interpretation. The algorithm's performance is compared with the clinical(More)
In patients with a repaired cleft palate, nasality is typically diagnosed by speech language pathologists. In addition, there are various instruments to objectively diagnose nasalance. To explore the potential of nasalance measurements after cleft palate repair by NasalView®, we correlated perceptual nasality and instrumentally measured nasalance of eight(More)
OBJECTIVES The aims of this study are to investigate the effects of diplophonia on jitter and shimmer and to identify measurement limitations with regard to material selection and clinical interpretation. MATERIALS AND METHODS Four hundred and ninety-eight audio samples of sustained phonations were analyzed. The audio samples were assessed for the grade(More)
