The study was done on 82 eyes having nasolacrimal duct obstruction and lacrimal stenosis or stenosis-obstruction. All were treated with dacryorhinostomy (DCR) and silicone intubation. The successful prevalence is 94.4%. Among them, the prevalence of functional success is 49.9%. The successful prevalence is increasing during the follow-up time. The intra-and post-operative complications are rare and mild. The causes and the form of obstruction are prognostic factors. The recurrent obstruction may occur when the silicone tube is still inside the canalcular

The acutely obstructed airway is a medical emergency that can potentially result in serious morbidity and mortality. Apart from the latest advancements in anaesthetic techniques, equipment and drugs, publications relevant to our topic, including the United Kingdom's 4th National Audit Project on major airway complications in 2011 and the updated American Society of Anesthesiologists' difficult airway algorithm of 2013, have recently been published. The former contained many reports of adverse events associated with the management of acute airway obstruction. By analysing the data and concepts from these two publications, this review article provides an update on management techniques for the acutely obstructed airway. We discuss the principles and factors relevant to the decision-making process in formulating a logical management plan.

The impact of respiratory function on children's craniofacial growth has received increasing attention from orthodontists and parents. There is a higher pediatric sleep-disordered breathing risk prevalence in the orthodontic population compared with a general population sample, and orthodontic practitioners need to pay close attention to the respiratory function of their pediatric patients. For children with upper airway obstruction and related dentofacial and functional abnormalities, clinicians should comprehensively consider the site and severity of upper airway obstruction, the clinical feature of malocclusion and other factors to develop an individual, multidisciplinary treatment plan, providing favorable conditions for the development of the children's craniofacial morphology and the whole body.

Tracheal papillomatosis is rare. When the disease starts during childhood, it usually appears to be self-limiting if properly managed. In adults, however, the disease sometimes rims a more protracted course with a higher risk of developing cancer. The tumors are derived from the tracheal surface epithelium and tracheal mucous glands and usually grow exophytically. Treatment has traditionally been with repeated endoscopic resection. However, in view of its viral origin, attempts have been made to control the disease with interferon. A67 years-old man was presented with exertional dyspnea. He was treated for bronchial asthma at another hospital. There was no improvement in his symptom. lie was referred to this hospital, and a bronchoscopic biopsy showed tracheal papillomatosis. lie was undergone bronchoscopic laser therapy with symptomatic improvement.

Objectives: To analyze the clinical characteristics and outcomes of neonates with upper airway obstruction (UAO) who were admitted via transportation, hence to provide more evidence-based information for the clinical management of UAO. Methods: This was a single center retrospective study. Patients were hospitalized in Beijing Children's Hospital from January 1, 2016 to May 31, 2021 with age <28 days or postmenstrual age (PMA) ≤44 weeks, and UAO as the first diagnosis. The general information of patients, obstructed sites in the upper airway, treatment, complications and prognosis were analyzed. The outcomes of surgical UAO vs. non-surgical UAO were analyzed by 2 by 2 χ² test. Results: A total of 111 cases were analyzed (2.3% of the total NICU hospitalized 4 826 infants in the same period), in which 62 (55.9%) were boys and 101 (91.0%) were term infants, and their gestational age was (38.7±2.0) weeks, birth weight (3 207±585) g, PMA on admission (40.8±2.5) weeks and weight on admission was (3 221±478) g. There were 92 cases (82.9%) with symptoms of UAO presenting on postnatal day 1, and 35 cases (31.5%) had extra-uterine growth retardation on admission. The diagnosis of UAO and the obstructive site was confirmed in 25 cases (22.5%) before transportation. There were 24 cases (21.6%), 71 cases (64.0%), and 16 cases (14.4%) who had UAO due to nasal, throat, and neck problems, respectively. The top 5 diagnosis of UAO were vocal cord paralysis (28 cases), bilateral choanal atresia (20 cases), laryngomalacia (15 cases), pharynx and larynx cysts (7 cases), and subglottic hemangioma (6 cases). The diagnosis and treatment of all the patients followed a multidisciplinary approach consisted of neonatal intensive care unit, ear-nose-throat department and medical image departments. A total of 102 cases (91.9%) underwent both bronchofiberscope and fiber nasopharyngoscope investigation. Seventy cases (63.1%) required ventilation. Among the 58 cases (52.3%) who required surgical intervention, 16 had tracheotomy. For cases with vs. without surgical intervention, the rate of cure and (or) improvement were 94.8% (55/58) vs. 54.7% (29/53), and the rate of being discharged against medical arrangement were 1.7% (1/58) vs. 45.3% (24/53) (χ²=24.21 and 30.11, both P<0.01). Conclusions: Neonatal UAO may locate at various sites of the upper airway. The overall prognosis of neonatal UAO is favorable. A multidisciplinary approach is necessary for efficient evaluation and appropriate surgical intervention.

OBJECTIVE: To investigate the therapeutic effects of 894 coblation-assisted treatment in adult with obstructive sleep apnea-hypopnea syndrome. METHOD: A review of 894 coblation-assisted treatment in adult with obstructive sleep apnea-hypopnea syndrome was presented with respect to the sleep monitoring results, SF-36 health questionnaire survey, therapeutic effects and complications. RESULT: After operation for 6 months, the patients' sleep Monitoring results were improved remarkably (P<0. 01) and their symptoms of snore or choke got improved. SF-36 health questionnaire survey showed that social function, energy and mental health dimension scores were significantly higher than the preoperative (P<0. 05). There were 18 patients suffered Secondarily bleeding within 2 weeks and 23 patients recrudesced within 1 year. CONCLUSION Radio frequency coblation is an applicable method of therapy for patients with obstructive sleep apnea-hypopnea. The treatments differ with the obstructive location and character of upper airway.

OBJECTIVETo summarize the clinical features of vascular malformations complicated with airway obstruction and to evaluate the therapeutic methods of these disease.

METHODSForty-seven children with airway obstruction and dyspnea (25 males, 22 females) were treated from Jun 1985 to Dec 2007, and their clinical data were retrospectively analyzed. Among 47 patients, there were 27 cases of venous malformations, 17 cases of macrocystic lymphatic malformations, and 3 cases of microcystic lymphatic malformations. Injection with absolute alcohol were performed in 20 patients with venous malformations, whereas both surgery and injection were performed in 7 patients with extensive or multiple lesions. Seventeen patients with macrocystic lymphatic malformations were treated with pingyangmycin injection. While surgery combined with pingyangmycin injection were used in other 3 patients with microcystic lymphatic malformations. According to the degree of airway obstruction and therapeutic conditions, tracheal intubation was performed in 27 patients, urgent preoperative tracheotomy was performed in 3 patients, prophylactic tracheotomy was performed in 2 patients, and postoperative tracheotomy was performed in 1 patient.

RESULTSTracheal intubation was remained for 24 to 48 hours in 30 patients, whose intubation was removed successfully in 29 patients except 1 patient who occurred dyspnea after removal of tracheal intubation resulting in tracheotomy. Tracheal cannula was successfully removed in all 6 patients 3 weeks to 4 months after the tracheotomy. There were 9 patients treated once, whereas injections were repeated 2 to 5 times in 38 patients. Necrosis of mucosa occurred in 2 cases after the injection with absolute alcohol, while temporary hemoglobinuria one occurred in 1. There were 5 cases of light or mediate fever after the pingyangmycin injection who recovered well after the symptomatic treatment. Follow-up lasted 1 to 23 years, 38 patients cured, 9 patients valid, and no patient invalid.

CONCLUSIONSIt is suggested that sclerotherapy should be the first choice in the treatment of vascular malformations complicated with airway obstruction, in which absolute alcohol should be used in venous malformations compared to pingyangmycin in lymphatic malformations. Combined therapy should be carried out in patients with extensive lesions in order to shorten the course of treatment and to get good therapeutic result.

OBJECTIVES: To study the clinical and bronchoscopic characteristics of tracheobronchial tuberculosis (TBTB) in children and to identify factors influencing residual airway obstruction or stenosis. METHODS: The clinical data of children with TBTB were retrospectively collected. The children were divided into two groups based on the last bronchoscopic result within one year of follow-up: a group with residual airway obstruction or stenosis (n=34) and a group without residual airway obstruction or stenosis (n=58). A multivariate logistic regression analysis was used to identify the factors influencing residual airway obstruction or stenosis in children with TBTB. Receiver operating characteristic (ROC) curves were used to analyze the predictive value of the factors influencing residual airway obstruction or stenosis in children with TBTB. RESULTS: A total of 92 children with TBTB were included, and the main symptoms were cough (90%) and fever (68%). In children under 1 year old, the incidence rates of dyspnea and wheezing were significantly higher than in other age groups (P<0.008). Chest CT findings included mediastinal or hilar lymph node enlargement (90%) and tracheobronchial stenosis or obstruction (61%). The lymphatic fistula type was the main type of TBTB observed bronchoscopically (77%). All children received interventional treatment, and the effective rate was 84%. During one year of follow-up, 34 children had residual airway obstruction or stenosis. The TBTB diagnostic time and the initiation of interventional treatment were significantly delayed in the group with residual airway obstruction or stenosis compared with the group without residual airway obstruction or stenosis (P<0.05). The multivariate logistic regression analysis showed that the TBTB diagnostic time was closely related to residual airway obstruction or stenosis in children (P<0.05). ROC curve analysis showed that at the cut-off value of 92 days of TBTB diagnostic time, the area under the curve for predicting residual airway obstruction or stenosis in children with TBTB was 0.707, with a sensitivity of 58.8% and a specificity of 75.9%. CONCLUSIONS The clinical manifestations of TBTB are nonspecific, and symptoms are more severe in children under 1 year old. TBTB should be suspected in children with tuberculosis and chest imaging indicating airway involvement. Delayed diagnosis of TBTB is associated with the development of residual airway obstruction or stenosis.
