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.

Objective:To investigate the prognostic impact of different tumor invasion patterns in the surgical treatment of T3 glottic laryngeal cancer. Methods:A retrospective analysis was conducted on the clinical data of 91 patients with T3 glottic laryngeal cancer. Results:Among the 91 patients, 58 cases （63.7%） had anterior invasion and 33 cases （36.3%） had posterior invasion. The posterior invasion was significantly correlated with invasions of the dorsal plate of cricoid cartilage （P<0.001）, arytenoid cartilage （P= 0.001）, and subglottic region（P = 0.001）. There was no statistical difference in survival outcomes between the total laryngectomy group and the partial laryngectomy group. But in the partial laryngectomy group, the 5-year disease-free survival（DFS） of patients with anterior invasive tumors was better than that of patients with posterior invasion tumors （HR: 4.681, 95%CI 1.337-16.393, P=0.016）, and subglottic invasion was associated with worse loco-regional recurrence-free survival（LRRFS）（HR: 3.931, 95%CI 1.054-14.658, P=0.041）. At the same time, we found that involvement of the dorsal plate of cricoid cartilage was an independent risk factor for postoperative laryngeal stenosis in partial laryngectomy patients （HR:11.67, 95%CI 1.89-71.98,P=0.008）. Conclusion:Compared with total laryngectomy, selected partial laryngectomy can also achieve favorable oncological outcomes. Posterior invasion and subglottic extension are independent prognostic factors for recurrence of partial laryngectomy in T3 glottic laryngeal cancer, and the involvement of the dorsal plate of cricoid cartilage is associated with postoperative laryngeal stenosis. The tumor invasion pattern of laryngeal cancer should be further subdivided in order to select a more individualized treatment plan.
