Background and Objectives：The prevalence rate of laryngeal cancer, the cancer known as good prognosis in comparison to other malignancy, accounts for 1% of all malignancy in Korea(Korea Central Cancer Registry, 2002). The purpose of this study is to review the treatment experiences of our hospital and find prognostic factors in laryngeal cancer patients. Materials and Method：A retrospective study was conducted on 244 laryngeal cancer patients between January 1987 through December 2003. Age, sex, TNM stage, 5 year survival rate, prognostic factors were analyzed. Results：The overall 5 year survival rate was 57.8%. The 5 year survival rate according to primary site and treatment method showed supraglottis 49.5%, glottis 79.2%, transglottis 28.2% and surgery only 71.4%, radiotherapy only 58.1%, post operative radiotherapy 47.2%, salvage operation 52.0%. There was no statistically significant difference among the results obtained by 4 different methods of treatment. but in supraglottis, surgery only has good 5 year survival rate(75.8%) compare to radiotherapy only(38.3%), postoperative radiotherapy(20.0%), salvage operation(43.7%) and there was statistically significant difference. The 5 year survival rate according to clinical stage and T status showed 84.1%, 37.2%, in stage I & II, III & IV respectively, 72.9%, 37.5% in stage T1 & T2, T3 & T4 respectively. The 5 year survival rate according to nodal status showed N(-)77.1%, N(+)35.6%. Conclusion：Those patient with early T stage, early clinical stage, glottic cancer, negative neck node and surgery only patient in supraglottis showed good treatment results in univariate analysis. The clinical stage and primary site of laryngeal cancer were found to be significant prognostic factors in laryngeal cancer patients in multivariate analysis.

Objectives: Despite various attempts to preserve the normal voice in advanced laryngeal cancer, it is inevitable for many advanced laryngeal cancer patients to undergo total laryngectomy and thus making a trade off between quality and quantity of life. Laryngectomees are faced with voice loss, change in physical appearance and health deterioration which hinder their efforts to rehabilitate back into their family and employment leading to poor quality of life. The objectives of this study were to evaluate the quality of life in long term surviving laryngectomees to, define the factors which are most important in determining their present quality of life and to propose a theoretical model for quality of life after laryngectomy in Korea. Materials and Methods: From 1986 to 1995, 120 laryngectomees with no evidence of disease were followed up for at least 3years were evaluated. Each of 15 quality of life domains with a total of ten points were given for a quality of life score. Results: There was no significant difference in the physical-mental adaptation index such as general health and mental health between the laryngectomees and control group(p>0.05). However, social adaptation index such as social activity, occupational status and economic status for laryngectomees were significantly lower with 2.3, 3.5, and 4.4 points compared to control group with 8.5, 7.6, and 7.1 points respectively(p<0.05). Conclusion : Vocational and social rehabilitation should be emphasized with highest priority for improving their economic status and thus improving their quality of life.

Background and Objectives : Vocal polyps are caused by inflammation induced by stress or irritation. Many patients with vocal polyps complain voice discomfort. For vocal polyps, surgery such as laryngeal microsurgery has been the mainstay of management. We analyzed the clinical features of vocal polyps, and how the size and location of vocal polyps affect the outcomes of surgery. Methods : We retrospectively reviewed 42 patients from March 2014 to December 2015, who were diagnosed as unilateral single vocal polyp. When we operated on a vocal polyp with laryngeal microscopy, we measured their size and location. The quality of voice was evaluated by GRABS scale, jitter, shimmer, NHR (noise to harmonic ratio), MPT (maximum phonation time), and VHI (voice handicap index) before operation and 4 weeks after operation. Results : When we divided the patients into large-sized vocal polyp group (the longest length >3 mm) and small-sized vocal polyp group (the longest length ${\leq}3mm$), all parameter differences tend to be greater at large sized vocal polyp. However, these differences were not statistically significant (p>0.05). When we divided into two groups depending on the volume of vocal polyp, no distinct tendency was found. When we compared the location (anterior, mid and posterior) of vocal polyp with the improvement of voice quality, more change was found at mid portion vocal polyp, except the difference of VHI. However, these differences were also not statistically significant (p>0.05). Conclusion : All parameter differences tend to be greater at large vocal polyp and polyp of the mid location.

Bilateral vocal cord palsy (BVCP) present a challenging condition which result from various etiologies including iatrogenic recurrent laryngeal nerve injury, progressive neurological disorder, intubation, trauma, tumor and idiopathic cause. Careful history taking, laryngoscopic evaluation, laryngeal EMG, and imaging studies are helpful for providing a precise diagnosis and planning appropriate treatment. BVCP causes airway restriction and not vocal dysfunction. In patients with BVFP, treatment is directed at maximizing the airway, while attempting to limit the negative effects of treatment on vocal function. A variety of surgical procedures are available for mangement of BVCP. The most conservative, limited procedure should be selected initially, and then further surgery and more extensive surgery can be tailored to the patient's airway and voice needs. This review will address the etiology, diagnosis, and managements of BVCP.

Inverted papilloma is a rare benign tumor which usually arises from sinonasal mucosa. We experienced a case of 62-year-old male who presented with foreign body sensation in throat. A round mass was found at right false vocal cord in laryngoscopic examination. It was excised in laryngeal microsurgery. The pathologic diagnosis was inverted papilloma of false vocal cord. Recurrence or complication did not occur during the follow up period of three months.

In this paper, we investigate the acoustic characteristics of sustained voices from normal subjects and patients with laryngeal pathologies. Perturbation methods (including jitter and shimmer), signal-to-noise ratio (SNR), and nonlinear dynamic methods (such as correlation dimension) are used to analyze normal and pathological voices. We find that jitter does not statistically discriminate between normal and pathological voices, but a significant difference is found for shimmer, SNR, and correlation dimension. The results suggest that nonlinear dynamic analysis may be valuable for the analysis of normal and pathological voices but perturbation analysis should be applied with caution for pathological voice analysis.

Schwannoma is a benign soft tissue tumor arising from the schwann cells of the nerve sheath. Although 25 to 45% of schwannomas arise in the head and neck region, larynx is one of the rarest sites of involvement. Recently, we experienced a case of a laryngeal schwannoma causing voice change in a 53-years-old woman. Laryngeal schwannoma is located right false vocal fold with bulging, which was completely removed by microlaryngeal surgical excision. We report a rare case with a review of literature.

기관무명동맥루는 매우 드물지만 높은 사망률을 보이는 질환으로, 장기간의 기관절개술이나 기관내 삽관후 합병증으로 발생한다. 대량 출혈로 인해 기도폐쇄 및 출혈성 쇼크로 생명의 위협이 초래되기 때문에 조기 진단과 즉각적인 치료가 반드시 필요하다. 후두 협착에 대한 수술을 위해 가능한 한 기관의 보존이 필요한 환자에 발생한 기관무명동맥루 환자에서 연골막을 포함한 늑연골을 이용한 기관성형술을 시행하였기에 보고하는 바이다.
