OBJECTIVETo explore the significance of laryngopharyngeal reflux (LPR) and gastroesophageal reflux (GER) in patients with vocal cord leukoplakia and early glottic cancer.

METHODSPatients with vocal cord leukoplakia and early glottic cancer encountered in Nanfang Hospital between December 2012 to January 2014 were included in this study. Ambulatory 24 hour multichannel intraluminal impedance-pH monitoring (MII-pH) was applied to obtain LPR and GER events, as well as the reflux properties of substances. Tobacco and alcohol history was also evaluated. Sixteen healthy volunteers were recruited as normal controls.

RESULTSThere were 26.3% (5/19) LPR patients in glottic cancer group, 35.3% (6/17) LPR patients in vocal cord leukoplakia group and 12.5% (2/16) LPR volunteers in normal controls. There was no statistically significant difference in the positive rate of LPR between early glottic cancer patients and normal controls as well as between vocal cord leukoplakia patients and normal controls (P > 0.05). There was statistically significance in numbers of acid reflux events, time of acid exposure, and time of acid clearance between vocal cord leukoplakia patients and normal controls as well as between glottic cancer patients and normal controls (P < 0.05). GER was found in 26.3% (5/19) patients in glottic cancer group and 23.5% (4/17) patients in vocal cord leukoplakia group and 6.3% (1/16) volunteer in normal controls. There was no statistically significant difference in the positive rate of GER between early glottic cancer patients and normal controls as well as between vocal cord leukoplakia patients and normal controls (P > 0.05). However, there was statistically significance in DeMeester scores between glottic cancer patients and normal controls (P < 0.05), while no statistically significance between vocal cord leukoplakia patients and normal controls (P > 0.05). Reflux events were dominated by acid and weakly acidic reflux in upright position. Weakly alkaline reflux events in upright position, acid reflux events in supine position, and weakly alkaline reflux events in supine position in vocal cord leukoplakia patients were significantly more than those in normal controls (P < 0.05). No statistically significant difference existed in positions and contents between early glottic cancer patients and normal controls (P > 0.05). There was also no statistically significant correlation between happening LPR and GER, smoking and drinking in patients with vocal cord leukoplakia and early glottic cancer (P > 0.05).

CONCLUSIONSReflux events are more in vocal cord leukoplakia patients and early glottic cancer patients, however, the relationship between laryngopharyngeal reflux and canceration of the vocal cord is still needed to be investigated. The significance of mucosal injury induced by nonacid refluxes is needed to be further studies.

Pediatric vocal ford paralysis is a vocal cord movement disorder caused by damage to the pediatric laryngeal motor nerves.It is mainly characterized by voice, breathing,and swallowing difficulties,and in severe cases,it can lead to choking in affected children. Currently, the diagnosis and treatment of this condition pose a significant challenge for pediatric otolaryngologists, as the goal is to minimize damage to the vocal folds and laryngeal framework.In order to standardize the diagnosis and treatment of pediatric vocal cord paralysis, the Pediatric Otolaryngology Committee of the Chinese Medical Association,in collaboration with multiple children's medical centers nationwide, have formulated this consensus document.

Objective: To investigate outcomes of laryngotracheal reconstruction (LTR)with anterior and posterior costal cartilage grafts in severe pediatric subglottic stenosis (SGS) or laryngeal web (LW). Methods: A review of patients with severe subglottic stenosis or laryngeal web between January 2020 and January 2022 was performed. Demographic features including gender, age at diagnosis, age at surgery, etiology, airway support, and other comorbidities were collected preoperatively. Patients were evaluated in surgical site, breathing, swallowing, phonation and complications postoperatively.Descriptive analysis was used in this research. Results: Eight patients were included: six with grade Ⅲ SGS following Cotton-Myer grading scale, and two with type Ⅲ LW following Cohen's classification. All patients underwent LTR with anterior and posterior costal cartilage grafts. Five patients underwent single-stage LTR (ssLTR), and three patients underwent double-stage LTR (dsLTR). Seven out of eight patients were able to successfully extubate or decannulate with normal swallowing function; four patients had mild hoarseness, and three had moderate hoarseness. One patient failed in extubation, and underwent tracheotomy. Conclusions: LTR with anterior and posterior costal cartilage grafts is an effective and safe treatment for severe SGS or LW. Careful preoperative assessment of disease severity and overall medical status will help selection between ssLTR and dsLTR, thereby maximizing patient outcomes for both modalities.

OBJECTIVE: To analyze the conservative management and outcomes of pharyngocutaneous fistula after total laryngectomy. METHOD: Twenty-one patients with postoperative fistulas were identified and treated by conservative therapy. RESULT: Different treatment were given basing on the three stages of pharyngocutaneous fistula: drainage and cleaning stage, pressure bandaging stage and healing stage. Fourteen patients (66.7%) with the conservative therapy resumed oral feeding after closure of fistula, the other 7 patients had to be cured by further operation. CONCLUSION Management basing on the stages of pharyngocutaneous fistula can achieve satisfied outcome. It can provide important information for pharyngocutaneous fistula's treatment.

OBJECTIVETo investigate the anatomic variation of nonrecurrent laryngeal nerve (NRLN) and its surgical identification and prevention during thyroidectomy.

METHODSThe database of 5 NRLN cases was analyzed to investigate the difference of operative maneuvers and procedures.

RESULTSAll 5 NRLN were located in the right side. Two cases were found have vocal cord paralysis and 1 case recovered in 3 cases who have NRLN injures.

CONCLUSIONSAny transverse bond should not be cut between vascular and laryngeal except middle thyroid vein. Recurrent laryngeal nerve (RLN) should be dissected during thyroid excision. Cervical pneumogastric nerve should be systematic dissected to detect whether RNLN is exist, if RLN is not exist in the same side.
