OBJECTIVE: To investigate the clinical feature, diagnose and therapeutic methods of paraglottic space primary paraganglioma. METHOD: One case of paraglottic space primary paraganglioma was reported and the relevant literatures were reviewed. RESULT: One case showed a hoarse voice, who was cured after the surgery of neck incision. NSE and CgA were positively expressed. CONCLUSION Paraganglioma of the paraglottic space is very rare. The diagnosis of paraglottic space primary paraganglioma bases on histopathology and immunohistochemistry. The immunohistochemistry and clinical character must be comprehensively analyzed to increase the diagnosis accuracy.

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.

OBJECTIVETo investigate the clinical features, minimally invasive treatment, and outcomes of subglottic hemangioma in infants.

METHODSFifteen cases of infantile subglottic hemangioma treated from January 2009 to December 2012 were retrospective analysed. Average time of onset was within 43 days-5 months of age. Seven cases had symptoms of laryngeal obstruction one week after birth, and 8 cases had symptoms within three weeks to six weeks after birth. Fourteen cases were unilateral and 1 case bilateral. No case had tracheotomy. Seven cases were hospitalised after intubation. Of which 5 cases with subglottic hemangiomas who failed to respond to pharmacologic treatment were treated by microdebrider under suspension laryngoscope. Ten cases accepted suction cutter suction.

RESULTSAfter surgery, nine cases were confirmed pathologically as capillary hemangioma. Average bleeding was 1-3 ml during operation, surgery usually lasted 10-15 minutes. No complications were found. Five cases required orotracheal intubation for 24 or 48 h after surgery, and no reintubation or tracheotomy was required in this series. Symptoms such as stridor and inspiratory retraction resolved approximately 12-72 h after surgery. Follow-up was 12-18 months after surgery, no systemic or local complications were observed, and no recurrence.

CONCLUSIONSThe treatment of subglottic hemangioma is individualised. If the tracheal stenoses ≥ 50%, with recurrent infection and acute laryngeal obstruction, removal of tumor with microdebrider is the minimally invasive, safe, simple and effective method with less complications. It is important that the anaesthetist should work well with otolaryngologist during operation.

OBJECTIVETo introduce a new surgical technique for the treatment of bilateral vocal cord paralysis.

METHODSTwenty-nine patients with bilateral vocal cord paralysis treated in Dalian Municipal Central Hospital between 2008 and 2012 were retrospectively studied. Coblation assisted arytenoidectomy was performed in all cases. The pre and postoperative glottic measurement and vocal acoustic parameters were analyzed.

RESULTSAll patients were decanulated 1 week after operation. Three months later, the mean glottic area increased from (21.9 +/- 4.7) to (40.3 +/- 5.2) mm2 (t = 5.74. P < 0.05); the width of maximal glottic chink increased from (1.47 +/- 0.37) to (4.82 +/- 0.54) mm (t = 6.24, P < 0.05). Twenty-six patients (89.7%) satisfied with the voice quality. Acoustic parameters (F0, jitter, shimmer) were no significant difference (P > 0. 05) , but there was a significant difference in maximum phonation time (P < 0.05). During three months to 3.5 years follow-up, the patients had a stable airway and effective phonation.

CONCLUSIONSEndoscopic coblation assisted arytenoidectomy is a new surgical method for the treatment of patients with bilateral vocal cord paralysis, which is efficient, minimally invasive and safe.

OBJECTIVETo evaluate the application of acellular dermal matrix (ADM) in the reconstruction of defect after head and neck tumor resection.

METHODSA total of 75 cases applied with ADM after head and neck tumor resection were reviewed. There were 47 cases of laryngeal carcinoma (glottic 41, supraglottic 3, and infraglottic 3), 5 cases of hypopharyngeal carcinoma, 11 cases of maxillary sinus carcinoma, 9 cases of oral cavity tumor, 3 cases of cervical trachea tumor. Among them 25 cases of laryngeal carcinoma, 4 cases of hypopharyngeal carcinoma, 7 cases maxillary carcinoma, 6 cases oral carcinoma, and one case of cervical trachea malignancy received postoperative adjuvant chemoradiotherapy. The patients were postoperatively followed up from 2 weeks to 3 years.

RESULTSAmong 75 cases, 65 cases, including 40 cases of laryngeal carcinoma, 4 cases of hypopharyngeal carcinoma, 9 cases of oral cavity tumor, 9 cases of maxillary carcinoma and 3 cases trachea tumor, presented with good wound healing without any complication within 3 months; the 47 patients with tracheotomy were decannulated successfully; 2 cases of laryngeal carcinoma and 1 case of hypopharyngeal carcinoma were complicated with pharyngeal fistula, which healed with dressing change, followed by decannulation; 5 cases had laryngeal stenosis and decannulation failed in these patients; and 3 cases of maxillary carcinoma had wound infection.

CONCLUSIONADM application is a easy and feasible method for the repair of the defect after head and neck tumor resection.

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.
