OBJECTIVE: To investigate the effect of the anteroposterior cricoid split on cartilage growth. METHOD: The rabbits were killed 8 months after the surgery of anteroposterior cricoid split. The larynxes were harvested and the cross-sectional area of the cricoid cartilage were calculated. RESULT: There was no significant difference in the cross-sectional area of the cricoid cartilage of these three groups. CONCLUSION The anteroposterior cricoid split might have no adverse effect on subsequent growth of cricoid cartilage.

OBJECTIVE: To study the treatment effect of CO2 laser and self-made laryngeal dilator on the laryngeal stenosis. METHOD: Twenty-five patients with laryngeal stenosis were treated with CO2 laser and self-made laryngeal dilator. The laryngeal cavity scar was resected as much as possible by using CO2 laser and the laryngeal cavity was exposed by placing laryngeal dilator under general anesthesia. RESULT: The 24 cases of all were successfully decanulated 1 to 12 months after operation and could breathe freely. One case had second operation and was successfully decanulated 9 months after operation. The follow-up for 1 to 2 years showed all cases speaking well and 3 cases recurrence. CONCLUSION The method for treating laryngeal stenosis using CO2 laser and self-mande laryngeal dilator is effective, fewer complication, less invasive, and faster recovery. The laryngeal dilator is made simply and conveniently.

This patient suffered from severe subglottic stenosis(grade Ⅳb). During partial cricotracheal resection, we cut through the cricothyroid membrane and the cricoid arch along the line from the lower edge of the thyroid cartilage to 5 mm of the inferior thyroid cartilage corner anteromedially. This can protect the cricothyroid joint, effectively protect the recurrent laryngeal nerve, and also support the airway. Strictly adhere to airway separation, avoid excessive separation of scars, and combine with reasonable postoperative management to achieve a safe extubation.

OBJECTIVE: To evaluate the clinical etiopathogenesis, the diagnose and the treatment of laryngotracheal stenosis in children. METHOD: Six patients with laryngotracheal stenosis who had been surgically were reviewed. RESULT: Three cases of congenital laryngeal cyst, among 2 cases were treated by undertaken endoscopic, one case was treated by laryngofissure. One case with congenital laryngeal web was treated by undertaken endoscopic with CO2 laser resection. One case with congenital tongue base cyst was treated by direct laryngoscope with puncture. One case with congenital cricoiddysplasty was treated by laryngotracheotomy with stent. One case of traumatic granuloma of trachea was treated by fence-form tracheotomy and inserting T-shape tube. Four patients were successfully decannulated, one patient was cured, one patient were followed-up. CONCLUSION The early diagnosis of laryngotracheal stenosis in children was important. The different methods of surgical used here for the laryngotracheal stenosis proved to be effective. The functions of laryngotracheal would been recovered with good voices and satisfactory airway.

Infants with laryngotracheal anomalies are clinically manifested as stridor or noisy breathing, choking, hoarseness, feeding difficulties, and cyanotic spells, followed by developmental and growth retardation and other health issues; in severe cases, patients may present with severe dyspnea, which is associated with high mortality. A timely diagnosis as well as appropriate strategy for laryngotracheal anomalies is still challenging for pediatric otolaryngologists. This consensus statement, evolved from expert opinion by the members of the Pediatric Otorhinolaryngology Professional Committee of the Pediatrician Branch of the Chinese Medical Doctor Association, provides comprehensive recommendations and standardized guidance for otolaryngologists who manage infants and young children with laryngotracheal anomalies in evaluation and treatment based on symptomatology, physical and laboratory examinations.

OBJECTIVETo study the effect of laryngotracheal reconstruction (LTR) in children with subglottic stenosis (SGS), and to discuss the indications and the risks of intraoperative and postoperative treatment of LTR.

METHODSFrom September 2008 to February 2010, 5 children (4 girls and 1 boy, aged 4 to 6 years) were treated by LTR. Among the 5 children, there were 2 congenital SGS and 3 acquired SGS. One had mild grade III SGS, 3 had severe grade III SGS, and one had grade IV SGS. One child with mild III SGS was treated by single-stage LTR, and the rest four children were treated by double-stage LTR. The surgical technique consisted of cricoid lamina midline vertical incision, rib cartilage graft interposition and endotracheal tube (ETT) stenting for 2 to 3 weeks.

RESULTSFour children with grade III SGS were de-cannulated 3 months after operation, and the child with grade IV SGS got de-cannulated 6 months after operation. Of all children, rib cartilage graft grower well, and the size of subglottis were amplified by grade III SGS to grade I SGS, and grade IV SGS to grade II SGS. All children obtained stable airway. One child with grade IV SGS who had hoarseness got effective phonation during follow-up 2 years after operation.

CONCLUSIONSLTR is a safe and effective treatment for pediatric subglottic stenosis. The important factors of successful operation are correct assessment and evaluation of the severity and overall medical status and selection of suitable surgical techniques.
