Etiology of inspiratory laryngeal stridor in children / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>Retrospective 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.</p><p><b>METHODS</b>All 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.</p><p><b>RESULTS</b>The 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).</p><p><b>CONCLUSIONS</b>The 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.</p>

Endoscopic surgery for nasopharyngeal angiofibroma / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To investigate the efficacy and the surgical techniques of transnasal endoscopic procedure for juvenile nasopharyngeal angiofibroma (JNA).</p><p><b>METHODS</b>Twenty-one nasopharyngeal angiofibroma patients were treated using transnasal endoscopic approach. They were divided into group A (without intracranial extension) and group B (minimal intracranial extension) according to the staging of Sessions. The patients were treated mostly with endoscopic surgery. In two midfacial operations cases, endoscopy was also used. The staging, average blood loss during surgery, tumor residual, and (or) recurrent tumor were evaluated.</p><p><b>RESULTS</b>Group A (19 cases) had an average blood loss of 1000 ml. Nineteen patients had no residual or recurrent tumor over a follow-up of 8-24 months. Group B (2 cases) had an average blood loss of 1500 ml. One of the patients had minimal residual tumor around the cavernous sinus, but showed no progression over a follow-up of 2 years. Another patient had no residual or recurrent tumor over a follow-up of 8 months.</p><p><b>CONCLUSIONS</b>The data suggests that transnasal endoscopic surgical techniques can be used to treat JNA which either limited to nasal and nasopharyngeal cavities or and the tumor with sphenoid and ethmoid invasions and even minimal intracranial extension.</p>
