BACKGROUND AND OBJECTIVES: The survival rate of laryngeal cancer has improved in recent day. But in case of advanced cancer, radical destructive surgery is required for survival. So early detection of laryngeal cancer prevent from this disastrous condition. In this point of view, mass screening test for early detection of laryngeal cancer is necessary. Screening tests using voice has many advantages of being simple, non invasive, and requiring less space. In this system, the most important factor is the selection of acoustic parameters to be used in voice analysis. Thus authors studied the acoustic parameters that can differentiate normal, benign, malignant laryngeal diseases by an acoustic analyzing system and we also checked the availability of parameters. MATERIALS AND METHODS: We evaluated the voice analyzed data from 25 laryngeal malignancy patients, 33 benign laryngeal disease patients, 35 normal control who visited PNUH otolaryngology department from October 1996 to May 1998. A computerized speech lab. 4300B (CSL) was used to carry out the analysis of each voice sample and statistical analysis, ANOVA. Canonical analysis and cumulative frequency curve were used. RESULTS: The statistically significant parameters that can differentiate normal and malignant laryngeal disease groups were 15 parameters and can differentiate normal and benign laryngeal disease group were 9 parameters and that can differentiate benign and malignant laryngeal disease group were 7 parameters. CONCLUSION: We consider that these parameters and detection programs may be effective in development of a screening system using voice only. Developing diagnostic tools and programs would need further study of phonetics and voice engineering.

BACKGROUND AND OBJECTIVES: Some objective and quantitative diagnositc methods are introduced to evaluate vocal cord paralysis, such as electro glottography (EGG) and laryngeal electromyography (LEMG). LEMG is an invasive and highly technical method requiring patient's cooperation. It records action potential generated when intrinsic laryngeal musculature contracts. EGG, on the other hand, records changes of impedence between both vocal cords when theses vibrate and represents many information of vocal cord movements. This method is non-invasive and very simple offering some valuable information about voice function of laryngeal diseases. MATERIALS AND METHODS: From January 1998 through May 2000, we evaluated 15 vocal cord paralysis patients by LEMG and EGG and compared the usefulness of these two methods by determining the lesions of vagal nerve injury. RESULTS: For patients who had severe recurrent laryngeal nerve injuries, EGG and dEGG showed no plateau phase but a loss of two-mass movements. Some showed very irregular saw-tooth shaped wave patterns. Patients with vagal nerve injury, EGG and dEGG showed relatively well maintained plateau phases because they had paralyzed cricothyroid muscles which are counteract to abductor of vocal cord. CONCLUSION: Although EGG did not provide information about such diseases as laryngeal myopathy and arthropathy, it is simple and non-invasive, and may he much valuable as a topodiagnostic method of vocal cord paralysis.

In some specific measurement, observations, and analyses of certain aspects of the voice and voice production used in phoniatrics, signs of various laryngeal disorders were identified, indicating that these tools can be used as aids in the diagnosis of laryngeal disorders.

OBJECTIVE:
To discuss the diagnosis and treatment method in children with mass in subglottic.
METHOD:
There were totally 35 patients with subglottic mass who complained with dyspnea in our department. All the patients got electronic laryngoscopy examination in order to get the preliminary judgment of the mass' property. Then they accepted ultrasound and CT scan to make the definite diagnosis. The patients with subglottic hemangioma accepted oral propranolol or intralesional Pingyangmycin injection. The other type of masses got the laryngoscope CO2 laser tumor resection.
RESULT:
There were 31 patients with subglottic hemangiomas, 2 patients with subglottic cysts, 1 patient with subglottic fibroma, 1 patient with subglottic granuloma. The substantial follow-up time was from 1 month to 3 years. 25 patients with subglottic hemangiomas were cured, 6 patients got improvement. The patients with non-hemangiomas were all cured.
CONCLUSION
There was a high incidence of hemangioma in children with subglottic mass. We suggested making a diagnosis by doing electronic laryngoscopy, ultrasound and CT scan step by step. Oral propranolol was a safe and effective method in treating subglottic hemangioma. For the patients with non-hemangiomas, we considered the laryngoscope CO2 laser tumor resection as the first choice of treatment.

The ex utero intrapartum treatment (EXIT) procedure was introduced to reduce fetal hypoxic damage while establishing an airway in fetuses with upper and lower airway obstruction. Delivery of the fetal head and shoulders while maintaining the uteroplacental circulation offers time to secure the fetal airway. Here, we report two cases of EXIT procedure for fetal airway obstruction, which were successfully managed with extensive preoperative planning by a professional multidisciplinary team.

Paradoxical vocal fold movement (PVFM) is a rare disease characterized by the adduction of vocal folds during inspiration. Since patients with PVFM may suffer from acute airway distress or inappropriate treatment for a long period of time, proper diagnosis by the otolaryngologist is critical to proper management. Case 1 was treated with voice therapy which involved self-awarness about what was happening inside his larynx during inspiration, the use of diaphragmatic breathing and laryngeal muscle tension reduction. Case 2 could not be treated with the initial voice therapy but the botulium toxin injection which was used as the second treatment option proved be successful.
