OBJECTIVE: To locate the recurrent laryngeal nerve fascicles in vagus and investigate the effect of the split-vagus nerve procedure to repair the paralyzed vocal cord in rats. METHOD: The method of dissection and acetylcholinesterase histochemical staining of neural fibers were used to locate the recurrent laryngeal nerve fascicles in vagus. Then 60 SD rats were divided into three groups. In experimental group right recurrent laryngeal nerve were incised and anastomosed to recurrent laryngeal nerve fascicles in vagus by means of the split-vagus nerve procedure...

The objective of the present work was to study the structure of voice disorders in children depending on the methods chosen to diagnose dysphonia. Medical histories of 1,451 children at the age varying from 2 months to 16 years were analysed. All of them were patients hospitalized for the first time between 1997 and 2007 to treat hoarseness caused by vocal cord nodules, functional or mutational dysphonia, chronic laryngitis, vocal cord paresis/palsy, recurring respiratory papillomatosis, vocal cord cystitis, and cicatrical laryngeal stenosis...

OBJECTIVE: To study the clinical effect of heterogeneity (cattle) acellular dunal matrix in repairing mucosa defect in laryngeal surgery. METHODS: Eighteen cancer patients with mucosa defect in central vocal area accepted treatment with heterogeneity acellular dunal matrix after surgery. There were two methods to repair mucosa defect. One was simple use of acellular dunal matrix, the second was combined use of acellular dunal matrix and muscle lamella or muscle and tendon film lamella...

OBJECTIVE: To study and evaluate the feasibility and effect of the treatment for juvenile recurrent laryngeal papilloma by nasal endoscopy electric suction cutting and laser surgery. METHOD: The clinical data of 26 cases with juvenile recurrent laryngeal papilloma from 2002-2007 years were retrospectively analyzed. Six cases were treated by electric suction cutting under nasal endoscopy, 20 cases were treated by electric suction cutting under nasal endoscopy and synergizing laser, and postoperative wound with sodium hyaluronate gel treatment...

OBJECTIVE: To analyze the clinical manifestations and the cause of misdiagnosis of congenital vallecular cyst. METHOD: Nineteen cases of congenital vallecular cysts were collected and reviewed retrospectively. Their clinical manifestations and diagnosis were analyzed. RESULT: Their clinical manifestations included inspiratory stridor, respiratory distress, inspiratory dyspnea, feeding difficulty etc. Among 19 cases, 15 cases were misdiagnosed as neonate pneumonia (9 cases), bronchial pneumonia (5 cases), and laryngitis (1 case), respectively...

Myasthenia gravis (MG) is an autoimmune disorder of neuromuscular transmission, usually recognized with ocular complaints or generalized muscle weakness. However, among the 1520 MG cases that had been diagnosed and treated in our hospital in the last 15 years (1990-2005), we have identified 7 MG patients whose initial and prominent complaint was dysphonia and all had been misdiagnosed elsewhere. The diagnoses were confirmed with fibrolaryngoscope and voice analysis employed before and after a positive neostigmine (anticholinesterase) test...

OBJECTIVE: To evaluate the clinical manifestations of laryngeal tuberculosis and its laryngoscopic characteristics. METHOD: Clinical analysis of 36 laryngeal tuberculosis cases confirmed pathologically was carried out retrospectively. RESULTS: The patients' ages ranged from 19 to 78 years old (median 39.5 years old). The male to female ratio was 1.8 to 1. The most frequent chief complaint was hoarseness (83.3%). The true vocal cord and the false vocal cord were usually found involved by fibrolaryngoscope observations...

OBJECTIVE: To summarize the clinical manifestation, operative method and therapeutic effect of various type of laryngeal web in infants. METHODS: The clinical data of 12 cases were analyzed, 5 cases of which were congenital laryngeal web (4 cases, glottic type; 1 case, subglottic type), 7 cases of which were secondary laryngeal web (1 case, tuberculous laryngeal web; 6 cases, traumatic laryngeal web). Diagnosis was mainly depended on history and clinical manifestation...

OBJECTIVE: To observe the relation between dermatomyositis/polymyositis and head-neck malignancy. METHOD: All 136 cases of dermatomyositis/polymyositis admitted to PUMCH during 10 years (1994-2003) were studied. The clinical features of 6 patients with an associated head-neck malignancy were analyzed. RESULT: There were 17 cases of malignancy in 136 patients with dermatomyositis/polymyositis, of which, 6 cases (6/17, 35.29%) were found to have head-neck malignancy: 4 cases of nasopharyngeal carcinoma, 1 case of non-Hodgkin lymphoma and 1 case of hypopharynx carcinoma...

OBJECTIVE: To study the safety and the immunogenicity of HPV6b virus-like particles (VLP) in children with juvenile laryngeal papilloma (JLP). The result of therapy is observed. METHOD: HPV6b VLP were expressed with HPV6b L1 recombinant baculovirus in sf-9 insect cells. Ten case of recurrent JLP were immunized with HPV6b VLP in 5, 10, 25 microg doses progressively and any local or systemic adverse events were recorded. By ELISA was used to detect the serum HPV6b VLP antibody (Ab) of JLPs samples in therapy different stage...

An analysis of a 121-day of intensive-care therapy of peritonitis and concomitant complications in a patient with Pickwick syndrome and somnolent apnea syndrome is reported. Right hemicolectomy was implemented in the patient for peritonitis, which developed on the 2nd day as a result of perforation of the blind gut at a place of tumor removed in a scheduled colonofibroscopy (CFS). The attempts of intubation of the trachea for as long as one hour failed due to the anatomic peculiarities. Tracheostomy was made...

Cricoarytenoid involvement in rheumatoid arthritis has been assessed in 32 patients by combining clinical evaluation, direct fiberoptic laryngoscopy (DFL), and high resolution computerized tomography (CT). Symptoms were inconstant, variable, and rarely prominent. Absence of symptoms does not exclude an involvement. One case presented as an acute respiratory distress. The study showed an unexpected frequency of involvement with 75% of abnormal DFL and 72% of abnormal CT. Semiology of laryngoscopy and CT are described...
