Vocal polyp is one of the representative chronic diseases of vocal folds, and it can be cured by voice therapy and/or laryngeal microsurgery. However, the existing therapeutic methods about vocal polyp are in great demand. The purpose of this study was to evaluate the effect of vocal improvement between laryngeal microsurgery and SKMVTT<SUP>®</SUP>(Seong-Tae Kim's Multiple Voice Therapy Technique), which was designed by the author. We identified 37 patients, who were diagnosed with unilateral vocal polyp, aged from 21 to 62 years(mean age: 46 years). 21 patients were treated by the SKMVTT<SUP>®</SUP> and the other 16 patients were only treated by the laryngeal microsurgery. All patients who were treated by the SKMVTT<SUP>®</SUP>, received 12 sessions of treatment, and were evaluated before therapy and after finishing the 12th session. The patients who were treated by laryngeal microsurgery, were evaluated prior to and at least 8 weeks after surgery. The results showed that the SKMVTT<SUP>®</SUP> produced better results compared to the laryngeal microsurgery alone. The SKMVTT<SUP>®</SUP> produced better results, especially, at the initial stage of voice therapy compared with those of laryngeal microsurgery. In this study, we can suggest that SKMVTT<SUP>®</SUP> may be useful in improving the voice qualities of vocal polyp patients. However, more data should be collected and evaluated to be widely used in other clinics.

Malignant tumors of the sinonasal tract constitute about 2% of those arising in the head and neck. Exposure to industrial fumes has been associated with an increased incidence of this malignant tumor. Early symptomatology of this cancer is identical to the symptomatology seen in benign conditions, such as swelling on forehead, headache, diplopia, and rhinorrhea. Thereby, delayed diagnosis leads to poor prognosis. Squamous cell carcinoma is the most common malignancy of the sinonasal tract, constituting about 80%, and primary carcinoma of the frontal sinus is extremely rare. Recently, authors experienced a case of primary carcinoma of the frontal sinus in a 60 year old male and performed transcranial resection. Now we report this case with brief review of literatures.
An irritable larynx syndrome is characterized by a sudden episodic dyspnea and dysphonia that is difficult to diagnose, and patients are often treated unnecessarily and/or too much. A correct diagnosis can be made by monitoring the larynx closing in the reversed direction during inhalation and posterior chink with videolaryngoscopy and by measuring a decrease in air flow volume during inhalation with a lung function test. Patients can be effectively treated with thorough differential diagnosis. Medications targeting precipitating factors, physical therapy sessions to improve abnormal larynx movement, counseling to reduce patients'anxiety rising from dyspnea, and etc. can effectively alleviate symptoms.
Background and Objectives : Surgery is considered the primary treatment for intracordal cyst. However, patients who had undergone surgery are still subject to recurrence and continued voice changes. Intracordal cysts naturally disappear in some patient population. Cyst does not always recur in patients who had received partial surgical removal, too. Contradicting results raises a question whether complete surgical removal of intracordal cyst is necessary and demonstrate need for better treatment. Herein, the author proposes novel surgical method technique intralaryngeal needle technique (INT), a technique using surgical needle for not only injection but also for aspiration and excision of cyst. This study aims to examine the potential of intralaryngeal needle technique in treating intracordal cysts. Materials and Methods : Surgical procedures were done on in-patients diagnosed with intracordal cyst. 23 patients received follow-up screening after the surgery for one year. Patients' subjective satisfaction levels, acoustic measures, aerodynamic measures, laryngeal stroboscopic results were compared before and after the treatment. Results : Overall patients were satisfied with novel surgical excision method. In terms of aerodynamic measures, maximum phonation time, mean air flow rate improved after the surgery. In terms of acoustic measures, Jitter, Shimmer, NHR, and voice pitch changes after the treatment showed statistically significant differences. Laryngeal stroboscopy results showed significant decreases in cyst sizes. Post-surgery patients had improved mucosal waves and amplitudes values. Conclusion : The results show the validity of intralaryngeal needle technique in reducing intracordal cyst size by excision, aspiration, and injection. The author believes this novel technique can be used as an alternative surgical method for intracordal cysts.
Background and Objectives:Laryngeal hyperkinetic movements of stuttering patients is similar to that of adductor spasmodic dysphonia. There has been studies on implementing botulinium toxin injections to treat stuttering. However, the opinions on the bouolinium toxin injection's effects on stuttering patients vary. In this study authors aim to figure out when the botulinium toxin injection improves stuttering patients. Materials and Methods:Stuttering patients who could receive botulinium toxin injection participated in this study. Age differences, gender differences, electroglottogrphic test, aerodynamic test in botulinium toxin injection treatment of stuttering were analyzed. Results:The botulinium toxin injection had statistically significant impact on patients who showed low mean air flow rate during aerodynamic study. Conclusion:The botulinium toxin injection could reduce stuttering of patients with low mean air flow rate in aerodynamic study.
