Diagnosis and management of orbital and cranial complications of pediatric acute rhinosinusitis / 中华耳鼻咽喉头颈外科杂志

Objective: To review the clinical characteristics, to illustrate diagnosis and management experience of orbital and cranial complications of pediatric acute rhinosinusitis. Methods: The clinical data of 24 children with orbital and cranial complications of acute rhinosinusitis who received endoscopic sinus surgery combined with drug treatment in Beijing Children's Hospital from January 2017 to December 2021 were retrospectively reviewed. There were 19 boys and 5 girls. The age varied from 13 to 159 months, with a median 47.5 months. The following diagnoses were obtained: 12 isolated subperiosteal orbital abscess, 2 associated with preseptal abscess, 2 associated with intraorbital abscess, 7 associated with optic neuritis, and 1 associated with septic cavernous sinus thrombosis. Clinical characteristics, organism isolated and outcomes were analyzed through descriptive methods. Results: All 24 patients presented with fever; 9 presented with nasal congestion and purulent discharge. The clinical manifestations of orbital infection included orbital edema, pain, proptosis and displacement of globe in all patients, while visual impairment was recognized in 7 children. Purulent drainage was cultured in 17 patients, among which 12 were positive. All patients underwent nasal endoscopic surgical interventions uneventfully, excluding one patient who required a second surgical procedure. Follow-up period ranged from 5 to 64 months. All patients resolved fully, with the exception of 2 children who got permanent blindness with visual loss preoperative. There was no recurrence or death. Conclusions: Orbital and cranial complications of pediatric acute rhinosinusitis could be severe with an occult onset. For patients with vison impairment, any signs of intracranial complications and a lack of response to conservative management, an urgent endoscopic intervention is needed.

Nasal endoscopic modified mucosal flap technique for repair of congenital choanal atresia in newborns and infants / 中华耳鼻咽喉头颈外科杂志

Objective: To describe and evaluate the surgical effect and prognosis of nasal endoscopic modified mucosal flap technique for repair of congenital choanal atresia in newborns and infants. Methods: The clinical data of 38 newborns and infants with congenital choanal atresia who underwent nasal endoscopic surgery in Beijing Children's Hospital between January 2016 and May 2018 were retrospectively analysed, including 13 males and 25 females. The age ranged from 5 days to 3 years old at the time of operation (15 cases were newborns). The clinical data, imaging data, treatment effect and prognosis were collected. According to the different surgical methods, the patients were divided into the conventional operation group and the modified mucosal flap technique group. The designs of the modified mucosal flap technique were designed according to the type of congenital choanal atresia. The cross-over L-shaped flaps were performed in patients with unilateral atresia, and the mirrored L-shaped flaps were performed in patients with bilateral atresia. All the patients were followed up for 2-3 years, and the follow-up parameters included the times of operations, length of hospital stay, restenosis rate and incidence of complications. Study data was analyzed using SAS version 9.4 statistical software. Results: Sixteen cases underwent conventional operation while 22 patients underwent modified mucosal flap technique under nasal endoscope. The lightest weight (2 200 g) and the youngest age (5 days) of the patients came from the modified mucosal flap technique group. Compared with the conventional operation group under nasal endoscope, the modified mucosal flap technique group had fewer times of operations (1.14±0.47 vs 2.69±1.20, t=5.552, P<0.001), shorter hospital stay ((7.70±3.22) d vs (14.37±19.16) d, t=2.960, P=0.005), lower rate of postoperative restenosis (9.1% vs 43.8%, χ²=6.156, P=0.013), and lower rate of the incidence of complications (13.6% vs 43.8%, χ²=5.955, P=0.015), the differences were statistically significant. Conclusion: The nasal endoscopic modified mucosal flap technique is feasible for repairing congenital choanal atresia in newborns and infants, which can significantly reduce the incidence of postoperative restenosis and complications.

Pediatric nasal neuroglial heterotopia: report of 13 cases / 中华耳鼻咽喉头颈外科杂志

Objective: To summarize clinical features and our experience of the diagnosis and treatment of pediatric nasal neuroglial heterotopia (NGH). Methods: Clinical data of 13 nasal NGH patients in Beijing Children's Hospital from August 2014 to October 2019 were retrospectively reviewed, including 9 boys and 4 girls, aged from 1 to 38 months with median age of 5 months. Radiological workups and excision of nasal NGH under general anesthesia were performed for all patients. B ultra-sound and MRI were performed for all external and mixed lesions, while ultra-low-dose CT scan and MRI for all intranasal type. Surgical approaches were dependent on location and extent of the lesions according to radiographic workup, including extranasal or transnasal endoscopic approach. Patients were followed up regularly after operation to evaluate the effect. Initial presentation, locations, imaging findings, surgical approaches and follow-up results were analyzed through descriptive statistical method. Results: Eight nasal NGH patients presented with an internal nasal mass and nasal obstruction, which belonged to intranasal type. Three patients presented with an external nasal mass which belonged to extranasal type and 2 patients had mixed lesions. The sites included nasal dorsum (n=5), anterior to the middle turbinate (n=5) and olfactory cleft (n=3). Surgical resections were done through median rhinotomy approach (n=5) or transnasal endoscopic approach (n=8). All the operations were successful and no complication occurred. All cases were followed up from 3 to 65 months. No recurrence was encountered. Conclusions: Nasal NGH is a rare lesion with atypical clinical presentation. Preoperative imaging including CT scan and MRI is essential for evaluation of the location, extent of the disease and for making the surgical plan. Treatment requires complete surgical excision.

Pneumomediastinum Secondary to Foreign Body Aspiration: Clinical Features and Treatment Explorement in 39 Pediatric Patients / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Pneumomediastinum (PM) secondary to foreign body aspiration (FBA) is rare in children. Although it is mainly benign, some cases may be fatal. Due to the rare nature of this clinical entity, proper assessment and management have been poorly studied so far. Here, we characterized the presentation and management of this clinical entity and provided an evaluation system for the management.</p><p><b>METHODS</b>We retrospectively reviewed children with PM secondary to FBA, who were treated in Beijing Children's Hospital from January 2010 to December 2015. All patients were stratified according to the degree of dyspnea on admission, and interventions were given accordingly. Bronchoscopic removals of airway foreign bodies (FBs) were performed on all patients. For patients in acute respiratory distress, emergent air evacuation and/or resuscitations were performed first. Admission data, interventions, and clinical outcomes were recorded.</p><p><b>RESULTS</b>A total of 39 patients were included in this study. The clinical severity was divided into three grades (Grades I, II, and III) according to the degree of dyspnea. Thirty-one patients were in Grade I dyspnea, and they simply underwent bronchoscopic FBs removals. PM resolved spontaneously and all patients recovered uneventfully. Six patients were in Grade II dyspnea, and emergent drainage preceded rigid bronchoscopy. They all recovered uneventfully under close observation. Two exhausted patients were in Grade III dyspnea. They died from large PM and bilateral pneumothorax, respectively, despite of aggressive interventions in our hospital.</p><p><b>CONCLUSIONS</b>PM secondary to FBA could be life-threatening in some patients. The degree of dyspnea should be evaluated immediately, and patients in different dyspnea should be treated accordingly. For patients in Grade I dyspnea, simple bronchoscopic FBs removals could promise a good outcome. For patients in Grade II dyspnea, emergent air evacuation and/or resuscitation should precede a bronchoscopy before the children become exhausted.</p>

Treatment of infantile subglottic hemangioma with oral propranolol / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To observe the efficacy of oral Propranolol in the treatment of infantile subglottic hemangioma.</p><p><b>METHODS</b>Eleven children (6 females and 5 males) with a median age at onset of treatment being 4 months were included in this study. Propranolol was given after laryngoscopy and a CT scan with contrast of the trachea confirming the presence of a subglottic hemangioma. The starting dose of Propranolol was 0.5 mg/kg per day, given in 2 or 3 divided doses. Heart rate and blood glucose were monitored during the treatment. If no side effects occurred, the dose was increased to 1 mg/kg per day at the third day and to 2 mg/kg per day at the sixth day. Treatment was continued at home after 10 days of inpatient treatment and the children were reevaluated monthly.</p><p><b>RESULTS</b>After 24 - 48 hours of treatment, all of the children had improvement in their airway obstruction which was confirmed by fibro-laryngoscopy. The diameter of the subglottic stenosis from the hemangioma decreased from 3.9 - 5.0 mm to 1.5 - 2.0 mm,and the color was also lighter than before. In 3 children with cutaneous hemangioma, there was also significant improvement in the cutaneous lesions after treatment, with the color becoming lighter. There were no significant ECG, blood pressure or blood biochemical changes during the treatment. Two of the children had hypoglycemia at the first dose, but improved after blood transfusion and changing their diet. In five children, the treatment was stopped after 6 to 11 months when the obstructive symptoms improved. None of the children in this group had any evidence of recurrence. In the 5 children who stopped treatment, the obstructing mass in the subglottis was less than 10% of the diameter.</p><p><b>CONCLUSION</b>Oral propranolol is a safe and effective treatment for infantile subglottic hemangioma. It may be used as a first-line therapeutic modality.</p>
