OBJECTIVETo investigate the risk factors that may relate with benign vocal fold lesions including vocal fold nodule, vocal fold polyp, chronic laryngitis and Reinke's edema

METHODSIn present series, 321 cases who were performed laryngoscope were invited to participate the survey. Among them 168 cases with benign vocal fold lesions composed the case group. Another 153 cases with normal larynx composed the control group. Each case were undertook the same questionnaire. Logistic regression analysis was preformed to investigate the possible risk factors.

RESULTSThe result demonstrated the occurring of benign vocal fold lesions positively correlated to five factors, including occupation, work or residence environment noise, alcohol-consuming, voice-using hours per day and abuse of voice. Occupations with intensive voice-use were more vulnerable to developing these disorders. Occurring risk of occupations type II with moderate voice-use was 1.934 times than that of occupations type I with lesser voice-use (OR = 1.934). And risk of occupations type III with upper voice-use was 2.633 times than that of type I. Risk raised 1.302 times with each more hour of voice use per day. OR of the following factors of voice abuse, environment noise, alcohol-consuming was 4.744, 2.115 and 2.177, respectively.

CONCLUSIONSThe result suggested that people should abstain from alcohol, lowering the environment noise, prevent overuse and abuse of voice in order to decrease the prevalence of these disorders, which is especially important for the professional voice users, e. g. teachers or managers. The essential therapy for these disorders is to correct bad phonation habits.

OBJECTIVERetrospective analysis was performed on the etiology of inspiratory laryngeal stridor in children. The purpose is to raise the diagnosis and cure rate of the disease.

METHODSAll patients were hospitalized in Children's Hospital from Jan, 2005 to Jan, 2007. Among of them, 245 cases were male and 133 cases were female. The median age was 4 months (range from 12 hours to 30 months). All the patients had chest X-ray examination. Two hundred and eighteen cases received chest CT scan, video laryngoscope, direct laryngoscope and bronchofibroscopy.

RESULTSThe diagnosis were as follows: acute laryngitis (140 cases), laryngomalacia (117 cases), acute laryngotracheal bronchitis (54 cases), vocal cord paralysis (18 cases), congenital tracheomalacia (9 cases), congenital laryngeal webs (8 cases), congenital cleft of larynx (6 cases), laryngeal cyst (6 cases), laryngeal papilloma (6 cases), acute epiglottitis (4 cases), congenital infraglottic stenosis (3 cases), tracheobronchial foreign body (3 cases), cysts thyrolinguals (1 case). All cases were cured except congenital tracheomalacia (9 cases), congenital cleft of larynx (6 cases), laryngeal papilloma (6 cases), congenital infraglottic (3 cases).

CONCLUSIONSThe etiology of inspiratory laryngeal stridor in children are very complicated. Video laryngoscope is recommended for all cases except for the acute inflammation disease. Chest CT scan and bronchofibroscopy may be necessary for some cases.

OBJECTIVEFor the purpose of improving the surgical effect of contact granuloma of larynx, a new surgical method was used and its effect observed.

METHODSUnder suspension laryngoscope, a part of cartilage of vocal process of arytenoid cartilage was removed until the cartilage was covered by local soft tissue after the granuloma was excised. Among 8 patients in this group, 7 were male, 1 female. Their ages ranged from 29 to 51(median 45 years old). The courses were 1 to 9 months (median 7 months). All patients experienced 1 to 5 times operations (median 2 times).

RESULTSUsing the new operative method, all 8 patients were cured for only 1 time, without recurrence followed- up for 1.5 years.

CONCLUSIONSThe granuloma were very easily recurred after the operation. The reason might be related to the exposure and inflammation of the local vocal process cartilage. The difficult key of the operation is exposure of granuloma and cartilage of vocal process because of intratracheal anesthetic tube.
