BACKGROUND Occupational voice disorders are characterized by rich symptomatology, which is dominated by symptoms by the vocal tract discomfort. Therefore, in the management it is important to consider these subjective complaints. The aim of the study was to assess the usefulness of using the vocal tract discomfort scale (VTD) in evaluating the effects of rehabilitation concerning occupational d...

Functional dysphonia (FD) refers to a voice problem in the absence of a physical condition. It is a multifaceted voice disorder. There is no consensus with regard to its definition and inclusion criteria for diagnosis. FD has many predisposing and precipitating factors, which may include genetic susceptibility, psychological traits, and the vocal behavior itself. The assessment of voice disorde...

This paper aims at finding suitable parameters for dysphonic voice analysis and classification. Moreover, a non-linear noise reduction scheme is proposed, for voice correction. Typical quantities from chaos theory and some conventional ones are evaluated, in order to provide entries for feature vectors in a feature space. Geometric signal separation is applied for voice classification, by means...

Patients who undergo total laryngectomy often experience difficulties with their voice, olfaction, and taste due to the lack of airflow through nasal oral cavities. While voice rehabilitation is more commonly performed, olfactory has gained importance in recent times use various techniques. Previous studies have shown that incidence hyposmia or anosmia (partial loss smell) after ranges from 25%...

Maintaining oral function in patients undergoing glossectomy boosts interventions such as prosthetic rehabilitation. However, current literature still fails in the presentation of results of prosthetic rehabilitation in relation to speech or swallowing. The objective of this research is to evaluate the effectiveness of prosthetic rehabilitation on voice, speech, and swallowing in patients under...

Cannulas and voice prostheses are mechanical aids for patients who had to undergo tracheotomy or laryngectomy for different reasons. For better understanding of the function of those artificial devices, first the indications and particularities of the previous surgical intervention are described in the context of this review. Despite the established procedure of percutaneous dilatation tracheot...

BACKGROUND The voice prosthesis inserted into a tracheoesophageal fistula has become the most widely used device for voice rehabilitation in patients with total laryngectomy. CASE PRESENTATION We describe a case of tracheoesophageal prosthesis' (TEP) aspiration in a laryngectomized patient, with permanent tracheal stoma, that appeared during standard cleaning procedure, despite a programme of...

Total laryngectomy, a surgical treatment for extensive cancer of larynx, which alters swallowing and respiration in patients, is followed up with a surgical voice restoration procedure comprising tracheoesophageal puncture techniques with insertion of a "voice prosthesis" to improve successful voice rehabilitation. However, microbial colonization is a major drawback of these devices. Antimicrob...
