Objective: To investigate the clinical characteristics of infant congenital tongue base cysts. Methods: This retrospective study involved 37 infants with congenital tongue base cysts in our hospital. Results: The median age at admission was 95 (15-360) d for these babies. The main clinical manifestations were laryngeal stridor (33/37 89.2%), dyspnea (8/37 21.6%), inspiratory trisomy (6/37 16.2%), and choking and vomiting milk (14/37 37.8%). Eight cases (21.6%) were misdiagnosed as laryngomalacia in another hospital, while 4 cases (10.8%) were misdiagnosed as pneumonia. One case required emergency intubation for rescue due to dyspnea before surgery. The root of the tongue was found to occupy space during intubation. Six cases (16.2%) had cysts found through CT examination. Three cases (8%) had cysts found during bronchoscopy due to pneumonia. The remaining cysts were found in the root of the tongue through laryngoscopy. Laryngoscopy was performed in all children before the operation, and CT examination in 28 patients before the operation showed that the median diameter of the cyst was 10 mm (5-20 mm), All children underwent radiofrequency ablation of glossal root cysts through laryngoscopy. Eight patients were transferred to the intensive care unit (ICU) for treatment post-operatively. The median intubation time was 4.5 days (2-5 days). Conclusion: Infancy congenital tongue base cysts have an early onset and atypical clinical manifestations. Electronic laryngoscopy combined with neck CT should be performed promptly in patients with laryngeal stridor and feeding difficulty to facilitate accurate diagnosis, and timely surgery is needed.

Objective. To discuss the presentation, evaluation, and management of congenital laryngeal webs. Methods: The Institutional approved this retrospective review of all patients who were diagnosed with laryngeal webs at our institution within the past 10 years. Results: There were 3 type I and II webs and 7 type III and IV webs; All 3 children with type I and II laryngeal webs recovered after a single endoscopic procedure, while children with type III and IV laryngeal webs usually had a record of multiple visits to the hospital with multiple treatments. In all 7 children with type III and IV webs, a tracheotomy was performed. The average age of the patients who underwent tracheotomy was 4.86 months（range，1-11mo）. Six of the seven children (85.7%) with type III and IV webs displayed subglottic stenosis. The ultimate treatment for such patients was open laryngoplasty. Conclusions: children with type III and IV laryngeal webs were more likely to have subglottic stenosis and needed to undergo tracheotomy earlier. They usually had a record of multiple visits to the hospital with multiple treatments. Open laryngoplasty combined with the implantation of a T-tube and reconstruction of the cricoid cartilage using hyoid bone may play a crucial role in the treatment of congenital laryngeal webs with subglottic stenosis.

Objective. To discuss the presentation, evaluation, and management of congenital laryngeal web. Methods.: The Institutional Board of Ethics of shanghai Children’s Hospital approved this retrospective review of all patients who were diagnosed with laryngeal web at our institution within the past 10 years. Charts mined for age at presentation, presenting symptoms, degree/location of web, associated syndromes, number/type of surgical procedures, and postoperative outcomes. Results.: Ten patients were included (6 male, 4female). There were 3 type I、II webs, 7 type III、IV webs; Children with type I and II laryngeal web were mainly presented with hoarseness and discomfort without any obvious respiratory distress（P＜0.05）. Children were usually older when they were presented to the hospital（p<0.05）, All the 3 children with type I and II laryngeal web recovered after a single endoscopic procedure. While children with laryngeal web type III and IV usually had a record of multiple visits to the hospital with multiple treatments（p<0.05） All of these 7 type III、IV webs , the tracheotomy was performed early, The ultimate treatment required for such patients was open laryngoplasty. Conclusions：There is a need for alertness regarding the neonatus exhibiting hoarseness and weak crying. To achieve a satisfactory outcome, it is essential to perform accurate preoperative staging and assessment along with an appropriate choice of treatment and placement of the laryngeal stent.
