Phonosurgery Training in Human Larynx Preserved with Thiel's Embalming Method.

Background: To describe the suitability of larynges preserved with Thiel's embalming method for phonosurgery training.

Methods: A training model for phonosurgery techniques simulating vocal pathology and glottal insufficiency is developed to compare and evaluate the perception of embalmed vocal cords through a voluntary and anonymous survey rated on a scale of 1-5. A total of 10 residents and young otolaryngologists participated in the surgical training in phonosurgery.

[Papillomas & laryngeal papillomatosis. Treatment with CO₂ laser surgery. Our experience over 15 years].

Objectives: The study goal was to evaluate the efficacy of CO₂ laser surgery in the treatment of laryngeal papillomatosis. We analysed several parameters such as gender, average age, relapse rate and viral serotype.

Material And Methods: A total of 26 diagnosed patients were included in this retrospective descriptive review.

Comparison of the Radiation Therapy Oncology Group recursive partitioning classification and Union Internationale Contre le Cancer TNM classification for patients with head and neck carcinoma.

Background: Prognostic models need to be tested in external validation studies to assess generalizability. Recursive partitioning analysis (RPA), a prognostic system based on the creation of a classification tree, has been proposed as a classification method in patients with head and neck carcinoma. The aim of this study was to compare the RPA and Union Internationale Contre le Cancer (UICC) TNM classification systems in patients with head and neck carcinoma treated consecutively in a single center.

Hypothyroidism in patients treated with total laryngectomy. A multivariate study.

One of the complications of the treatment of head and neck carcinoma patients is hypothyroidism. The objective of our study was to quantify the prevalence of hypothyroidism in patients with laryngeal or hypopharyngeal cancer treated with a total laryngectomy and to evaluate the importance of different variables in the appearance of hypothyroidism in this group of patients. A transversal study in 182 patients treated with total laryngectomy between 1986 and 1998 was carried out.
