[Malignant tumors of the oropharynx].

Data on 31 patient suffering from malignant tumors of oropharynx were analyzed during a 5 year period at the Clinic for otorhinolaryngologic diseases. Oropharynx carcinoma was pathohistologically diagnosed in all patients. It is an illness which occurs in older people, in 87% in patients older than 60 years of age, and mostly in males (9:1). 77.4% were smokers, 83.8% consumed alcohol while 38.7% were treated for alcoholism. The first and most frequent symptoms are odynophagia (58.1%) and dysphagia (38.7%). Metastases of lymph nodes of the neck were present in 64.5% of the sick at the time when sickness was diagnosed and all were ipsilateral. 25.8% of patients were surgically treated and 6 of them were also treated by radiation. 54.8% of patients were primarily treated with telecobalt therapy. Three year survival in 3 patients points to extremely negative localization of the malignant process with a bad course and outcome.

[Classification of dysphonias based on the primary etiologic factor (part I)].

INTRODUCTION: Phonation is a complex integral function of the organism. Regular phonation is characterized by: clarity and adequate pitch. Dysphonia is a disorder of phonation. It may have many acoustic forms, but hoarseness is the best known symptom of dysphonia. Acoustic phenomena are caused by: aperiodicity of vocal vibration, turbulent air flow in the glottis and incomplete glottis closure. PREVIOUS CLASSIFICATIONS OF DYSPHONIAS: The best known classification of dysphonias was introduced by Perello. There are two groups: organic dysphonias and functional dysphonias. On the 8th Congress of Union of European Phoniatricians, in Koszeg (Hungary, 1979), Majdevac proposed a new classification. CLASSIFICATION OF DYSPHONIAS: We are proposing a new classification, made according to the primary etiologic factor in dysphonias. In this paper, we shall consider the first four. I DYSPHONIAS CAUSED BY PRIMARY FUNCTIONAL DISORDERS: This group includes: 1. Hyperkinetic dysphonia grade I 2. Hyperkinetic dysphonia grade II 3. Hypokinetic dysphonia 4. Contact hyperplastic dysphonia 5. Dysodic dysphonia II DYSPHONIAS CAUSED BY PRIMARY NEUROGENIC DISORDERS: This group includes: 1. Central dysphonias 2. Spasmodic (spastic) dysphonia 3. Dysphonia caused by myasthenia gravis 4. Dysphonia within skull base syndromes 5. Dysphonia caused by unilateral palsy of the inferior laryngeal nerve 6. Dysphonia caused by bilateral palsy of the inferior laryngeal nerve 7. Dysphonia caused by palsy of the superior laryngeal nerve III DYSPHONIAS CAUSED BY PRIMARY PSYCHOGENIC DISORDERS: This group includes: 1. Psychogenic aphonia 2. Psychogenic dysphonia 3. False mutation IV DYSPHONIAS CAUSED BY PRIMARY SOMATIC DISORDERS: This group includes: 1. Dysphonia caused by insufficiency of vocal cords 2. Dysphonia caused by oedema of vocal cords 3. Dysphonia caused by laryngitis (secondary functional) 4. Cord-ventricular voice 5. Posttraumatic dysphonia 6. Arthrogenic dysphonia 7. Presbyphonia CONCLUSION: Dysphonia is a disorder of phonation which originates at the glottis level. When disorders of phonation are concerned it is necessary to study the organism as a whole as well as all mechanisms which take part in voice production. In that case the damaged part of the phonation system can be diagnosed, which enables efficient medical treatment of the disorder.

[Classification of dysphonias based on the primary etiologic factor (part II)].

INTRODUCTION: Phonation is a complex integral function of an organism. Regular phonation is characterized by: clearness and adequate pitch. Dysphonia is a disorder of phonation. It can have many acoustic forms, but hoarseness is the best known symptom of dysphonia. Acoustic phenomena in regard to voice are caused by: irregularities in vocal cord vibration, turbulent airflow in the glottis and obstruction of glottis. PREVIOUS CLASSIFICATIONS OF DYSPHONIAS: The best known classification of dysphonias was introduced by Perello. There are two groups: 1. organic dysphonias and 2. functional dysphonias. On the 8th Congress of the Union of European Phoniatrists, in Köszeg (Hungary, 1979), Majdevac proposed a new classification. CLASSIFICATION OF DYSPHONIAS: We are proposing a new classification according to the primary etiologic factor of dysphonias. In this paper, we shall consider four gropus: from the fifth to eighth. V DYSPHONIAS CAUSED BY PRIMARY ENDOCRINE DISORDERS: This group includes: 1. Dysphonia caused by pituitary disorders 2. Dysphonia caused by thyroid gland disorders 3. Dysphonia caused by parathyroid glands disorders 4. Dysphonia caused by pancreatic function disorders 5. Dysphonia caused by suprarenal function disorders 6. Dysphonias caused by sexual glands function disorders 7. Intersexuality. VI DYSPHONIAS CAUSED BY COMPLEX PROFESSIONAL REASONS: This group includes: 1. Permanent hyperkinetic dysphonia 2. Permanent hyperkinetic dysphonia with vocal cord nodules 3. Dysphonia caused by myogenic imperfect closure of vocal cords 4. Phonastenia. VII DYSPHONIAS CAUSED BY PRIMARY DISPLASTIC DISORDERS: This group includes: 1. Dysphonia caused by laryngeal hypoplasia 2. Dysphonia caused by laryngeal asymmetry 3. Dysphonia caused by epiglottal anomalies 4. Dysphonia caused by laryngeal diaphragm. VIII DYSPHONIAS CAUSED BY LARYNGEAL TUMORS: This group includes: 1. Dysphonia caused by benign tumors 2. Dysphonia caused by malignant tumors. CONCLUSION: Dysphonia is a disorder of phonation which originates from glottal level. Disorders of phonation require observation of an organism as a whole and studying all mechanisms which take part in voice production. This provides examination of voice disorders, their establishment and adequate treatment.

[Partial laryngectomies].

After introduction of partial laryngectomies into the treatment of malignant larynx tumors, within a research project we analyzed symptoms, occurrence and the type of partial larynx resections for the two year period (October 1990 to September 1992). During this period of time 111 patients with malignant tumors were operated, while total laryngectomy was performed in 50 (45.0%). Laryngomicroscopy was performed in 14 patients (12.6%), and in 47 patients (42.3%) one of the partial resections of larynx was performed. Horizontal laryngectomy was performed in 25 patients (22.5%), while one of the vertical laryngectomies in 22 patients (19.8%). Concerning horizontal laryngectomies the following were performed: horizontal glossectomy, horizontal supraglottic laryngectomy and horizontal supraglottic laryngectomy spread to the tongue base, arytenoid and vocal cord. Concerning vertical laryngectomies the following were performed: hordectomy, frontal, frontolateral laryngectomy, vertical laryngectomy and hemilaryngectomy.
