The benefits of this new material, as demonstrated in animal studies and preliminary studies in man, could provide the answer to problems encountered by surgeons in the field of phonatory implants. This novel application is a step towards resolving the very real problems which still exist in the field today. The functional concept, which will allow better control over integrating implants in tissue, should also, it is hoped, favour cellular colonization, thereby fulfilling a currently unmet medical need. The aim is to avoid well-identified potential complications linked to the use of silicone-only implants (with or without a surface coating), like leakage around the prosthesis (by cellular colonization), and so reduce the risk of protrusion/extrusion of the prosthesis as far as possible, and to avoid trauma to the peri-prosthetic tissues by repeated interventions

Concurrent Chemoradiation Versus Surgery With Adjuvant Therapy in Advanced Laryngopharyngeal Cancers

Surgery with post operative radiotherapy (PORT) had been the mainstay of treatment for advanced laryngeal-pharyngeal cancers (ALHC) until the eighth decade of the past century. Total laryn...

Clinical Feasibility of New Tracheoesophageal Puncture Set

During a total laryngectomy a puncture is created in the tracheoesophageal wall and a voice prosthesis is inserted. With this voice prosthesis the patient learns to speak again. During thi...

Laryngectomy Education

Patients undergoing total laryngectomy are at high risk for 30-day unplanned readmission. Many of these readmissions are related to stomal care, and it is thought that the readmissions cou...

The Korean Version of the Voice Symptom Scale for Patients with Thyroid Operation, and Its Use in a Validation and Reliability Study.

The Voice Symptom Scale (VoiSS) questionnaire is a self-reported measure of voice function. Compared with previous voice-rating tools, the VoiSS focuses more on communication difficulties, pharyngeal ...

A pneumatic Bionic Voice prosthesis-Pre-clinical trials of controlling the voice onset and offset.

Despite emergent progress in many fields of bionics, a functional Bionic Voice prosthesis for laryngectomy patients (larynx amputees) has not yet been achieved, leading to a lifetime of vocal disabili...

Efficacy of Laryngectomy alone for Treatment of Locally Advanced Laryngeal Cancer: A Stage and Subsite Specific Survival Analysis.

Total laryngectomy is a well-established treatment for locally advanced laryngeal cancer. Evidence for the benefit of post-operative radiotherapy after laryngectomy in patients with locally advanced p...

Association of a Perioperative Education Program With Unplanned Readmission Following Total Laryngectomy.

Patients undergoing total laryngectomy (TL) are at high risk for 30-day hospital readmission. Strategies to decrease the readmission rate remain unknown.

Bocca's hemipharyngo-total laryngectomy for hypopharyngeal carcinoma to avoid reconstruction with a pedicled flap.

Major pharyngeal defects after total pharyngolaryngectomy for hypopharyngeal squamous cell carcinoma (SCC) frequently demand reconstruction strategies that include myocutaneous pedicled flaps, such as...

Medical and Biotech [MESH] Definitions

Total or partial excision of the larynx.

Pathological processes that affect voice production, usually involving VOCAL CORDS and the LARYNGEAL MUCOSA. Voice disorders can be caused by organic (anatomical), or functional (emotional or psychological) factors leading to DYSPHONIA; APHONIA; and defects in VOICE QUALITY, loudness, and pitch.

That component of SPEECH which gives the primary distinction to a given speaker's VOICE when pitch and loudness are excluded. It involves both phonatory and resonatory characteristics. Some of the descriptions of voice quality are harshness, breathiness and nasality.

Tumors or cancer of the PHARYNX.

A variety of techniques used to help individuals utilize their voice for various purposes and with minimal use of muscle energy.
