Background and Objectives : Proton pump inhibitors(PPIs) improve the symptoms of laryngopharyngeal reflux(LPR). But there is little reports about the changes of each items in reflux symptom index (RSI) and reflux finding score (RFS) after PPIstreatment. The purpose of this study is to analyze the changes of pre- and post-treatment score in each RSI and RFS items after 8 weeks medication with proton pump inhibitors in laryngopharyngeal reflux patients. Methods : Prospective study. Among the patients who had visited the department of otolaryngology from January 2007 to December 2008, 91 patients who had shown scores greater than 13 on the RSI and/or 7 on the RFS were studied. All patients received PPIs once daily before breakfast for 8 weeks. RSI and RFS were assessed at initial, four weeks and eight weeks after medication. Result: All RSI items were improved (p < 0.05). The globus sense followed by throat clearing, heartburns and hoarseness showed high initial RSI score than other items. And globus sense, throat clearing, hoarseness and heartburn were improved significantly more than others items. But only posterior commissure hypertrophy of RFS was improved significantly more than others items. Conclusion: Empiric PPIs therapy reduced the RSI scores and more effective for symptoms such as globus sense, throat clearing, hoarseness and heartburn among suspected LPR patients. In RFS, only posterior commissure hypertrophy has improved significantly. However, the changes of each categories of RFS were minimal (average: 0.16), therefore clinical significance is restricted in RFS.

Background and Objectives： Complications arising from endotracheal intubation are uncommon but, when they do occur, can be significant. Placement of an endotracheal tube frequently results in trauma to the underlying laryngeal and tracheal tissue, although the trauma is usually reversible. Occasionally, these changes can be of a more permanent nature and result in severe impairment of the airway and/or voice. It is proposed that a common factor-gastroesophageal reflux-might be responsible. This study was performed in order to develop the animal model of LPRD using rats and investigated that LPRD could produce significant damage to larynx especially vocal cords. Materials and Methods : The each four rats were used in the experiment and control study. Each was anesthetized and larynx was exposed and injured in the unilateral aritenoid. Injured site was contact with normal saline(control group) and synthetic gastric juice(experimental group). The larynx was examined after 7days in normal environment. Results : All was survived in the control group and two was survived in the experimental group. In the control group, some inflammation cells was found but in the experimental group, granulation was found. Conclusion : We developed animal model of LPRD using rat and thought LPRD may Play an important role in the development of permanent laryngeal injury.

Background : LPRD(Laryngopharyngeal reflux disease) gives rise to inflammatory change in the pharyngolaryngeal tissue with various otolaryngologic symptoms. Ranitidine, histamine H2receptor antagonists, are currently used as therapeutic medications. However, the efficacy of Ranitidine on LPRD has not been proven yet. Objectives : We intended to analyze the efficacy of the Ranitidine on LPRD. Materials :md Methods : In 20 multicenter, 607 patients with LPR(laryngopharyngeal reflux) symptom were observed to evaluate their symptoms and laryngoscopic findings after 4 weeks, 8 weeks, and 12 weeks of treatment of Ranitidine. Results : The symptom of LPR including globus sensation, sore throat hoarseness, regurgitatioin are improved after 4 weeks $86.2\%,\;8 weeks\;91.5\%,\;12 weeks\;92.9\%$ of Ranitidine treatment and improved after 4 weeks $91.5\%,\;8 weeks\;94.5\%,\;12 weeks\; 97.2\%$ of Ranitidine combined with prokinetics. The rates of sore throat, chronic cough, globus sensation improvement at 8 weeks after treatment are $26.7\%,\;16.7\%,\;16\%$. Conclusion : In patient with LPR, Ranitidine treatment reduces LPR symptoms very effectively.

Background and Objectives: Although laryngopharyngeal reflux disease (LPRD) is a widely recognized disease in the field of otolaryngology, controversies still exist regarding the diagnosis and treatment for it. The purpose of this survey was to find out current trends in diagnosis and management of LPRD among Korean otolaryngologists. Materials and Method: Questionnaires were obtained from 26 Korean otolaryngology specialists by electronic balloting, and 46 members of the Korean Society of Head and Neck Surgery (KSHNS) bye-mail. Survey participants were asked about their preferences in diagnostic policy, duration/dosage of antireflux treatment, and their familiarity to the reflux symptom index (RST) and the reflux finding scores (RFS). Results: The majority of the survey participants (64%) preferred empiric therapy trial with proton pump inhibitors (PPIs) based on patients' symptoms and their laryngeal findings. PPIs alone (27%) or PPIs with prokinetics (32%) were usually prescribed as a first line treatment mostly with once daily schedule in the morning before meal and for less than 4 months of duration (86%). More than 90% of participants were aware of the RSI and RFS, but less than 50% of them were actually using those items in the clinics. Conclusion: Most of Korean otolaryngologists who participated in this survey answered that they prefer starting empirical treatments with proton pump inhibitors mainly based on the patient's symptoms and their laryngeal findings.

Background and Objectives : To determine the changes of reflux symptoms and laryngoscopic findings of patients with laryngopharyngeal reflux (LPR) on the duration of proton pump inhibitor medication. Materials and Methods : From Feb 2003 to Nov 2004, 58 patients who were diagnosed with LPR by 24-hour double-probe pH monitoring were enrolled. All patients were treated with proton pump inhibitor and followed up for 8 weeks at least. The response of symptoms and laryngoscopic findings of patients were assessed with reflux symptom index (RSI) and reflux finding score (RFS) before treatment and 2, 4, 8, 12, 16, 20 weeks after treatment. Results : The symptoms of patients with LPR were improved significantly at 2, 4, 8 weeks of treatment. The laryngoscopic findings of patients with LPR were improved significantly at 4 and 12 weeks of treatment. There was no correlation between improvement of reflux symptoms and laryngoscopic findings. Conclusions : The laryngoscopic findings of LPR patients were improved more slowly than reflux symptoms. Based on our results, anti-reflux therapy might be continued at least for 3 months until the improvement of laryngoscopic findings.

Background and Objectives : Laryngopharyngeal reflux disease (LPRD) is relatively common disease. N-acetyl cysteine (NAC) has both mucolytic and antioxidant effect, also may be beneficial in inflammatory airway diseases. The purpose of this study was to evaluate the efficacy and safety of inhaled NAC therapy in LPRD. Materials and Method : We retrospectively reviewed the medical records of 525 LPRD patients at 12 medical centers. Finally 401 patients subjected to inhaled NAC therapy for 2 months were enrolled in the study. We analyzed the change of Reflux Symptom Index (RSI) and Reflux Finding Score (RFS) after use of NAC for 4 weeks and 8 weeks in addition to the patient's compliance of the treatment. Results : The RSI score significantly decreased from $19.87{\pm}6.34$ to $12.78{\pm}6.93$ after 4 weeks and to $10.65{\pm}7.47$ after 8 weeks. The RFS score also significantly decreased from $9.29{\pm}3.4$ to $7.17{\pm}3.41$ after 4 weeks and to $6.1{\pm}3.73$ after 8 weeks (p<0.05). During the treatment periods, 42 patients (10.4%) reported to have 80 episodes of discomfort. Throat discomfort (33%) and nausea (28%) were most common complaints, but the duration of discomfort was usually less than 4 weeks. Conclusion : Inhaled NAC treatment is highly effective for the reduction of both subjective and objective findings in LPRD patients. This study will provide the evidence of new treatment option for patients with LPRD. However, further studies will be needs to assess the real effect of inhaled NAC therapy as a standard treatment regimen of LPRD.

Dysphonia is a medical terminology for voice disorders characterized by hoarseness, harshness, weakness, or even loss of voice ; any impairment in ability to produce voice sounds using the vocal organs, larynx, The causes of dysphonia can be classified into two groups, organic and functional. Functional dysphonia includes spasmodic dysphonia, muscle tension dysphonia, mutational dysphonia and conversion dysphonia, etc, The findings of laryngoscopy in these dysphonia are almost normal. Therefore, physicians should diagnosis these diseases from careful history taking and abundant understandings about the phonation pattern, Organic dysphonia is caused by anatomical problems in the larynx, especially on the vocal fold, Some lesions, however, are not easily found because these lesions are too small, or located on the lower lip of vibrating vocal fold. Laryngopharyngeal reflux induced laryngitis, vascular lesions, sulcus vocalis, vocal atropy including presbylaryngis, and mucosal tears are common lesions easily missed in laryngoscopy, Therefore, a high index of suspicion is necessary to avoid missing vocal fold mucosal lesions, and the strobovideolaryngoscopy is indispensable in making the diagnosis,

Granuloma is an uncommon benign disease that develops in the process of wound healing. Pharyngeal or laryngeal granuloma can be associated with gastric reflux, mechanical injury or trauma including intubation, voice abuse, or foreign body. 50-year-old female was transferred to our institute with a huge mass occupying the upper aerodigestive tract causing dysphagia. The patient has been suffering from a brain hemorrhage for several months and was kept in bed due to the quadriplegia with stuporous mental status, and was tracheotomized. On examination, the whole oropharynx and hypopharynx was covered by a smooth-surfaced soft big diffuse granular mass, which extended down to the upper trachea through the larynx. The huge granuloma was successfully removed with surgery and was found to have a pedunculating stalk on the oropharyngeal posterior wall with a small mucosal defect, suggestive of the origin of the mass. The defect was closed primarily after the cauterization. The patient is now followed up regularly without any recurrence of the disease.

연구배경 : 구개수구개인두성형술(uvulopalatopharyngoplasty : UPPP) 은 폐쇄성 수면 무호흡 증후군 환자에서 가장 보편적으로 시행되고 있는 외과적 치료법이지만 치료 효과에 대하여는 논란의 여지가 많으며, 국내 연구 자료는 매우 부족한 실정이다. 방 법 : UPPP를 시행한 폐쇄성 수면 무호흡 증후군 환자들 중에서 일차 추적 수면다원검사가 가능했던 26명을 대상으로 단기 치료 효과를 관찰하였다. 치료 효과는 두가지 기준에 의해 평가하였다. 첫 번째는 일반적인 평가 기준으로써, UPPP 시행으로 무호흡지수(apnea index : AI) 혹은 무호흡-저호흡지수(apnea-hypopnea index : AHI)가 50% 이상 감소한 경우 혹은 UPPP 시행 후의 AI가 10 미만이거나 AHI가 20 미만인 환자들을 효과가 있는 경우 즉 반응군으로 정의하였고, 두 번째는 저자들이 설정한 평가 기준으로써, UPPP 시행 전의 AI 혹은 AHI와 관계없이 UPPP 시행 후의 AI가 5 미만이거나 AHI가 10 미만인 환자들을 단기적으로 폐쇄성 수면 무호흡 증후군이 치유된 경우 즉 치유군으로 간주하였다. 비만도, AI 및 AHI와 UPPP 시행에 의한 AI 및 AHI 감소율과의 관련성을 관찰하였고, 수면 구조를 비교함으로써 UPPP의 시행으로 수면의 질이 개선될 수 있는지 여부를 분석하였다. UPPP 시행 후 10일 이내에 발생한 문제점을 조기 합병증으로 정의 하였고, 10일 이후에 발생한 부작용은 후기 합병증으로 분류하였다. 결 과 : 26명의 환자 중에서 반웅군은 18명(69.2%) 이었고, 10명(38.5%)은 단기적으로 폐쇄성 수면 무호흡 증후군이 치유된 소견을 보였으며 5명(19.2%)은 UPPP 시행 후에 AI 혹은 AHI가 오히려 증가되었다. UPPP 시행 전의 비만도는 AI 감소용 및 AHI 감소율과 상호 관련성이 없었고, UPPP 시행 전의 AI는 AI 감소율과 상관관계가 없었으며, AHI 역시 AHI 감소율과 관련성이 없었다. 전체 대상 환자, 반웅군 및 비반웅군, 치유군 및 비치유군 각각에서 UPPP 시행 전후 수면 구조의 유의한 변화는 없었다. UPPP 시행에 따른 조기 합병증으로 비교적 심한 수술 부위의 통증, 음식물의 비역류, 기침이나 호흡곤란 등의 호흡기 증상, 수술 부위의 출혈, 연하곤란, 귀의 통증 혹은 봉합 부위 파열 등이 전체 환자(100%)에서 발생하였고, 후기 합병증으로 인후의 건조감, 비역류, 음성의 변화, 연하곤란, 인후의 이물감 혹은 미각변화 등이 22명(84.6%)의 환자에서 관찰되었으나, 합병증은 모두 경미한 것이었다. 결 론 : 폐쇄성 수면 무호흡 증후군 환자의 약 70%가 UPPP의 시행으로 호전을 보이지만, 치료 효과가 충분한 경우는 약 40%에 불과하였다. 치료 효과를 높이기 위해서는 엄격한 기준에 의한 적응증의 결정과 더불어 적절한 수술 방법이 필요할 것으로 생각한다.

Background and Objectives: Gastric acid reflux is known to be the most important cause of contact granuloma. Therefore, anti-gastric acid reflux medication has been used as the first line treatment although there are other treatment methods such as surgery or steroid injections. Actually, the role of surgery in the treatment of contact granuloma has not been established clearly. The purpose of this study was to evaluate the effectiveness of surgical treatment for contact granuloma. Materials and Methods: We retrospectively reviewed the medical records of 14 patients who were diagnosed with contact granuloma and treated with surgery from 2011 to July 2016 at Hanyang University hospital. Results: Of 14 patients, 9 (64.3%) were male and 5 (27.4%) were female. The mean age was 53.8 (${\pm}6.1$) years. The main symptoms were voice change followed by globus, dyspnea, and asymptomatic. Mean Reflux Finding Score (RFS) before surgery was 13.5 and mead Reflux Symptom Index (RSI) was 10.4. The causes of surgery were inadequate response to proton pump inhibitor (PPI) in 4 cases, airway obstruction with large granuloma in 8 cases, and differential diagnosis in 2 cases. Of 14 patients, recurrence occurred in 8 (53.3%) patients after surgery. In 8 recurrent cases, 5 patients showed complete remission and 3 patients showed partial remission with PPI medication. Conclusion: The role of surgery in the treatment of contact granuloma might be limited due to high recurrence rate.
