Subglottic cyst is a rare cause of laryngeal tinnitus in infants and young children, and only a few cases have been reported at home and abroad. In this paper, we report the clinical characteristics and treatment experience of three cases of subglottic cysts in Children's Hospital of Nanjing Medical University. All the 3 childrem were prematurechildren, with a history of tracheal intubation, and the main symptoms were coughing and wheezing.Electronic nasopharyngolaryngoscopy revealed spherical neoplasm under the glottis. Neck computed tomography （CT） showed a slightly hypodense shadow with poorly defined borders, and no significant enhancement was observed after enhancement. Under the self-retaining laryngoscope, the new organisms were clamped and nibbled, and the cyst wall was cauterized by low temperature plasma. There was no recurrence in postoperative follow-up.

OBJECTIVE: Laryngomalacia is the most common cause for stridor in neonate and infant. Our study aims at assessing the outcome of surgical management in patients diagnosed by fibrolaryngoscope as congenital Laryngomalacia. METHOD: Retrospective study of 16 patients undergoing surgery for severe laryngomalacia. The patients' symptoms, associated medical conditions and surgical management were recorded. RESULT: Stridor and feeding difficulty were observed in 16 patients on admission, while dyspnea was found in 11 patients. Medical co-morbidities exist in 14 cases. The mean age of surgery was 23 weeks, 15 patients had follow-up records for 24 months. Fourteen cases underwent supraglortoplasty. Tracheotomy was performed on the other 2 cases complicated with tracheomalacia. Nine cases showed full recovery of stridor 48 hours post-supraglottoplasty, and 7 were free of feeding difficulties. In the 6 months follow-up, complete or partial relief was achieved in all main symptoms and signs. CONCLUSION Supraglottoplasty is effective in relieving stridor and feeding difficulty as well as respiratory insufficiency, which makes it a first line option for managing severe laryngomalacia.

OBJECTIVE: Using meta analysis to assess the local recurrence of CO2 laser surgery for patients with early glottic carcinoma (Tis, T1, N0, M0, T2 N0 M0). METHOD: The Chinese data library (like Wanfang, Weipu, Chinese Periodicals library), PubMed, EMBASE, OVII) and Proquest Medical Library were searched according to including and excluding standard. The reference was screened, quality evaluated and information extracted. Meta analysis was processed by RevMan 5.0. Data including local recurrence after CO2 laser surgery for patients with stage Tis, T1 N0 M0,T2 N0 M0 glottic carcinoma was pulled using appropriate model according to their homogeneity or heterogeneity. RESULT: A total of 27 studies were included in this meta analysis. Group Tis versus T1: P = 0.08, no statistical significance; Group T1a versus T1b: P < 0.01, great statistical significance; Group T1 versus T2: P = 0.09, no statistical significance; Group anterior commissure+ versus anterior commissure: P < 0.01, great statistical significance. CONCLUSION The local recurrence varies from different kinds of TNM classification of early glottic carcinoma after CO2 laser surgery. There is no statistical significance between group Tis versus T1 and group T1 versus T2. The local recurrence in T1a is lower than in T1b. The local recurrence in group anterior commissure+ is higher than in group anterior commissure+.

OBJECTIVE: To investigate the feasibility and clinical characteristics of small partial laryngectomy without tracheotomy for T1-2 stage glottic carcinoma. METHOD: Forty-five patients with laryngeal squamaous cell carcinoma in T1-2 stage received small partial laryngectomy without tracheotomy. RESULT: All patients were primarily healed and were hospitalized for an average of 11.5 days post-operatively. In all patients, the function of respiration and the reflection of cough were normal, and laryngeal obstruction did not happen. The only postoperative complication was subcutaneous emphysema noted in 29 patients. Among them, subcutaneous emphysema extincted after 4-6 days in 26 patiens, only 3 patiens suffered from delayed healing because the subcutaneous emphysema extincted after 2 weeks. Mild subcutaneous emphysema did not affect the function of respiration and deglutition, healing of wound, and psychology of patients. All patients had been followed-up for 1-13 years. Only 2 patients died of tumor recurrence or metastasis. The function of respiration and deglutition were normal in the living patients, and no implanting metastasis on surface of trachea were found. CONCLUSION The theoretical foundation of small partial laryngectomy without tracheotomy for T1-2 stage glottic carcinoma has been well established. This surgical technique is feasible, safe and effective. It can significantly improve clinical outcome of T1-2 stage glottic carcinoma with minimal invasiveness. Furthermore, it can obviously abate the surgical, physiological and psychological trauma on patients.

OBJECTIVE: To study clinical characteristics, diagnosis, pathological types and therapy methods of nonsquamous cell neoplasm in subglottis, in order to improve comprehension of this rare disease. METHOD: To analysis 3 patients' clinical data with noosquamous cell neoplasm in subglottis by reviewing related literature, and to generalize the symptoms, differentiation and treatment experience of nonsquamous cell neoplasm in subglottis. RESULT: Among the 3 patients, one's main complain was hoarseness and the other two's main symptom was inspiratory dyspnea. As diagnosis was definite and acute obstruction of airway was relieved, the neoplasms were removed totally. Two patients were undergone operation through oral cavity by using suspended laryngoscope, and one patient was done surgery by neck approach. Paraffin wax result showed that one patient suffered epithelial-myoepithelial carcinoma, who received radiotherapy after surgery. There is no recurrence in all patients by following up more than 1 year. CONCLUSION The occurrence of nonsquamous cell neoplasm in subglottis is relatively low, and the subglottis should be inspected carefully to avoid missed diagnosis. Operation is the preferred method to treat this kind of disease. To choose a suitable operational manner according to size, location of the neoplasm is crucial.

OBJECTIVE: To investigate the effectiveness external radiation (XRT) vs transoral laser surgery (TOL) for treatment of early glottic carcinoma. METHOD: Medline (1990-2010), Embase (1990-2010), Cochrane Library, CBM (1990-2010), CNKI (1994-2010), Wanfang Database were searched for published case-control studies investigating the effectiveness external radiation vs transoral laser surgery for treatment of early glottic carcinoma. The odds ratio was calculated. Meta-analyses were performed by RevMan5. 0. 2 Software. RESULT: In the complications of this study, there was significant heterogeneity in the literatures, so Meta analysis was given up. In the recurrence and 5-years locoregional control, XRT group was no significant difference with TOL group by eliminating the heterogeneity or using the subgroup analysis, but the results till showed there was less recurrence and more locoregional control in TOL group than those in XRT group. In death of disease, overall survival and laryngeal preservation, the differences were statistically significant. CONCLUSIONS TOL could be complete in the clinic and the cost was much more cheaper than XRT. So TOL could be used as the first choice for the treatment of early glottic carcinoma versus XRT. But for larger tumors, involving the anterior commissure, there was no clear conclusion. Based on literatures, traditional surgery was the proposed choice. We recognize that the datas included in our study are retrospective studies, for a more scientific conclusion, we need more RCTs.
