Modern people has been increased interest about health care and maintenance as emerging well-being and social issues. In particular, the smoking is not good for the recognition much greater importance is the massive spread of the smoking is low. The smoking has much adverse effects body's respiratory and circulatory organ many and it is recognized as a serious danger to our health the smoking as well as secondhand smoking. In this paper, we were carried out study analysis comparison to apply though voice analytical elements techniques have a influence vocal cords and formants in the environment smoking and secondhand smoking. For this purpose, we organized subjects group smoker and nonsmoker in 20's man and to collect voice of the smoke and Secondhand Smoking before after then we carried out study analysis experimental results Pitch, Jitter, Shimmer, 5~8 Formant Frequency.

IgG4-related disease is a fibroinflammatory condition by infiltration of IgG4-positive plasma cells that often presents as a tumorous lesion. This disease can affect nearly every organ system. After the pancreas, the head and neck region is second most common site for presentation of IgG4-related disease such as Mikulicz's disease, Küttner tumor. The involvement of IgG4-related disease in laryngeal lesions is extremely rare. We have experienced a case of IgG4-related disease with pseudotumor formation in the larynx that is suggestive of malignancy in radiologic findings. But the pathology findings was finally confirmed as IgG4-related disease. Oral treatment with prednisolone was initiated, and the edematous mass reduced in size without permanent functional impairment of vocal fold mobility. We report our experience with a literature review.

The larynx has three major functions such as protective reflex, respiration and phonation, and is richly innervated by sensory, sympathetic and parasympathetic nerves. The sensory innervation of the laryngeal mucosa, which is involved in the perception of pain, mechanical and chemical irritation, prtects the airway via various laryngeal reflexes. We studied the distribution of Substance P (SP) and Calcitonin Gene-Related Peptide (CGRP) sensory fibers in the rat's larynx using the immuno-histochemical methods. Many SP and CGRP immunoreactive fibers were found in all regions of the laryngeal mucosa except the vocal cords. SP immunoreactive fibers showed a very similar distribution to the CGRP fibers in the epithelium and submucosa. But SP immunoreactive fibers were sparser than CGRP immunoreactive fibers in distribution density. Both reactive fibers were denser in the supraglottic region than subglottic region. Especially, intraepithelial fibers displayed the densest innervation to the laryngeal surface of the epiglottis. h the subepithelium, SP and CGRP immunoreactive fibers were distributed along the wall of vessels and around the glands. The present results suggest that the regional distribution of SP and CGRP immunoreactivity may be responsible for the protective reflex function of the laryngeal inlet.

The early pulmonary consequences of inhalation injury are well documented; however, little is known about delayed pulmonary complications following thermal inhalation injury. Although thermal injury below the vocal cords is rare because of effective heat dissipation in the upper airway, inflammatory endobronchial polyps have previously been reported as a delayed complication associated with inhalation injury. We report an extraordinary case of tracheobronchial polyps in patients with smoke inhalation injury. This report shows the delayed development and natural course of tracheobronchial polyps following thermal injury.

Tremor is a rhythmic, involuntary muscular contraction characterized by oscillations(to-and-fro movements) of a part of the body. The most common of all involuntary movements, tremor can affect various body parts such as the hands, head, facial structures, vocal cords, trunk, and legs; most tremors, however, occur in the hands. Tremor often accompanies neurological disorders associated with aging. Although the disorder is not life-threatening, it can be responsible for functional disability and social embarrassment. The clinical study was carried out the 4 patients with tremor who were treated in Dong Seo Medical Center from 1 January 2005 to 31 August. The results were summarized as follows. Tremor has relation to liver according to Jangbu theory. So we performed acupuncture treatment(Ganseonggyeok) and Herbal medication on tremor. After our treatments, tremor and some other symptoms were improved.

Awake fiberoptic nasotracheal intubation is a useful technique, especially in patients with airway obstruction. It must not only provide sufficient anesthesia, but also maintain spontaneous breathing. We introduce a method to achieve this using a small dose of fentanyl and midazolam in combination with topical anesthesia. The cases of 2 patients (1 male, 1 female) who underwent oral maxillofacial surgery are reported. They received $50{\mu}g$ of fentanyl 2-3 times (total $2.2-2.3{\mu}g/kg$) at intervals of approximately 2 min. Oxygen was administered via a mask at 6 L/min, and 0.5 mg of midazolam was administered 1-4 times (total 0.02-0.05 mg/kg) at intervals of approximately 2 min. A tracheal tube was inserted through the nasal cavity after topical anesthesia was applied to the epiglottis, vocal cords, and into the trachea through the fiberscope channel. All patients were successfully intubated. This is a useful and safe method for awake fiberoptic nasotracheal intubation.

Tracheal invasion is an uncommon complication of thyroid cancer, but it can cause respiratory failure. A rigid bronchoscope may be used to help relieve airway obstruction, but general anesthesia is usually required. Tracheal balloon dilatation and stent insertion can be performed without general anesthesia, but complete airway obstruction during balloon inflation may be dangerous in some patients. Additionally, placement of the stent adjacent to the vocal cords can be technically challenging. An 86-year-old female patient with tracheal invasion resulting from thyroid cancer was admitted to our hospital because of worsening dyspnea. Due to the patient's refusal of general anesthesia and the interventional radiologist's difficulty in completing endotracheal stenting, we performed endotracheal tube balloon dilatation and argon plasma coagulation. We have successfully treated tracheal obstruction in the patient with thyroid cancer by using endotracheal tube balloon inflation and a flexible bronchoscope without general anesthesia or airway obstruction during balloon inflation.

Laryngeal web is formed from various causes, and it is a scar tissue covered with epithelium on both sides. The purpose of the laryngeal web surgery is to cover the vocal cords with healthy epithelium and to achieve the normal or near normal function of respiration and phonation. Until now, a lot of surgical procedures were introduced, but have some merits and disadvantages. Recently authors tried this new surgical technique on 6 patients using the suspension laryngomicroscope under the intubation general anesthesia, which was to suture the upper and lower edges of the severed web. This new approach has several advantages; 1) familiar instruments and visual field 2) no unnecessary surgical trauma beyond the operation field 3) one stage operation 4) shorter operation time 5) no serious complications 6) short hospitalization, etc.

Thyrotomy is very useful surgical procedure for laryngeal lesions; however, the web-formation at the anterior part of vocal cords is a frequent troublesome sequel of this procedure. Since the anterior commissure is not injured in Hayashi's hemithyrotomy, a web never results from this procedure. But the intralaryngeal exposure is too small to perform the surgery in this method. Partial thyrotomy was deviced as a new surgical technique to the glottic subglottic lesion. In partial thyrotomy, surgical procedure can be easily carried out under local anesthesia, in a wide field. This procedure has no side effects such as the web-formation at the anterior commissure, nor dyspnea after the surgery.

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.
