introduction: bnign laryngeal lesions are relatively commonly occurring problems which are often noted after changes in voice. since they are non-invasive and yield objective easy-to-collect data, acoustic laboratory methods are used along with perceptual assessments for evaluation of voice. studying acoustic characteristics is useful in diagnosis and treatment of voice disorders.  with regard ...

Pathologies in the larynx and trachea in the pediatric age can be characterized in 4 main groups: airway stenosis, acute infections, benign neoplasia and foreign body aspiration. In this review main diagnostic strategies and therapeutic options are presented. Laryngomalazia is the most frequent condition of supraglottic stenosis. The term supraglottoplasty summarizes all different techniques us...

the speech is an easily accessible signal which clearly represents the characteristics of larynx and vocal folds. therefore, application of some proper machine learning algorithms on a small part of a recorded speech signal may help in non-invasive diagnosing of vocal fold diseases. since there are some experimental evidences that suggest the existence of chaotic behavior in speech production s...

Background: Flexible laryngoscopy is less operator/patient dependent diagnostic procedure with magnified field and well tolerated procedure. tolerable clear visualization of interior larynx. Aim: To audit the flexible laryngoscope in outpatient department our local setting. Methods: A retrospective survey was carried out Outpatient ENT Department Akbar Niazi Teaching Hospital, Islamabad between...

With the present development of digital registration and methods for processing speech it is possible to make effective objective acoustic diagnostics for medical purposes. These methods are useful as all pathologies and diseases of the human vocal tract influence the quality of a patient's speech signal. Diagnostics of the voice organ can be defined as an unambiguous recognition of the current...

Cell techniques find increasing application in modern clinical practice. The II and III phases of clinical trials are already under way for various cellular products used for the restoration of the functions of the cornea, larynx, skin, etc. However, the obtainment of functional cell types specific to different organs and tissues still remains a subject of laboratory research. Liver is one of t...

This review highlights the possibilities of photodynamic therapy (PDT) using drugs based on chlorin e6, aluminum phthalocyanine, methylene blue as photosensitizers for bacterial and fungal pathologies. method was developed initially to treat tumor diseases, where it had shown its high efficiency safety. Now is actively used in treatment cancers skin, bronchi, stomach, cervix, larynx, or other r...

A rational approach toward the development of improved techniques for the prevention, detection, diagnosis, and correction of vocal pathologies rests on an improved understanding of voice mechanisms. To achieve these goals, we need to better understand the dimensions of phonatory performance and their dependence both on the state of laryngeal structures and on patterns of control. Because of th...

Case report The purpose of this paper is to present an atypical case of Ludwig’s angina, whose initial presentation suggested a diagnosis of a large laryngeal tumor. The patient, 62 years old, without other known pathologies, came to the Emergency Room with severe dyspnea, dysphagia, high fever, and severe hypoxemia. It enters in respiratory arrest and dies less than 24 hours after the initial ...
