Practical insights for paediatric otolaryngology surgical cases and performing microlaryngobronchoscopy during the COVID-19 pandemic.

Paediatric otolaryngology practice involves examining and operating in anatomical locations with high levels of aerosol generation and transmission of COVID-19 to treating clinicians, especially from the asymptomatic patient populations including children. During the COVID-19 pandemic all emergent otolaryngological conditions affecting the airway, oral, and nasal cavities should be managed medically where possible and any operating deferred. We present guidelines for operating on paediatric otolaryngological patients when necessary during the COVID-19 pandemic, and incorporate experience gathered during microlaryngobronchoscopy on a COVID-19 positive infant at our institution.

Surgical aspects of cochlear implantation in syndromic children.

OBJECTIVE: The objective of this study was to report surgical results and outcomes of cochlear implantation in a large series of children with syndromes from one centre. PATIENTS AND METHODS: All syndromic children who underwent cochlear implantation at Great Ormond Street Hospital, from January 2000 to December 2010 were included in this study. The surgical technique was analysed and audiological outcomes were collected. RESULTS: Over the 10-year period of this study, a total of 88 cochleas in 67 children with syndromes were implanted. The common syndromes implanted in this study were Ushers syndrome (23 patients, 33 cochleas), Wardenburgs syndrome (8 patients, 9 cochleas), Pendreds syndrome (4 patients, 4 cochleas), Jervell-Lange-Neilsen syndrome (3 patients, 4 cochleas), Enlarged vestibular aqueduct syndrome (4 patients, 7 cochleas), Cogans syndrome (3 patients, 4 cochleas), CHARGE (5 patients, 6 cochleas), and Branchio Oto Renal syndrome (3 patients, 4 cochleas). Pre-operative radiological inner ear anatomy was found to be abnormal in 28.4% (25/88) cochleas in this study group. Full insertion of the electrode was achieved in 93.1% (82/88) of cochleas, partial insertion in three cochleas, and insertion was abandoned in three cochleas. Early complications were seen in 6.8% (6/88) of implantations. All the 64/67 children who were implanted are still using the implant. CONCLUSION: Cochlear implantation in syndromic children is challenging in both its audiological and surgical aspects. Good surgical results and good audiological and speech outcomes were achieved in this study, and subjective improvement in quality of life was achieved in these patients.

Sodium tetradecyl sulphate sclerotherapy for treating venous malformations of the oral and pharyngeal regions in children.

OBJECTIVE: Venous vascular malformations in the head and neck region present a difficult management challenge. We describe our experience of using sodium tetradecyl sulphate injection sclerotherapy to treat children presenting with venous malformations of the oral and pharyngeal region. METHODS: We performed a retrospective case note review of consecutive children treated at our institution between 2004 and 2011. Patient notes were analysed for demographic details, site and size of lesion, number and duration of treatments, treatment response and complications. RESULTS: Twelve patients were included (7 boys and 5 girls, mean age 7 years). Sites of lesions included tongue, floor of mouth, pharynx, tonsillar fossae, parapharyngeal space and soft palate. All patients were treated with 3% sodium tetradecyl sulphate (STS) foam injected trans-orally or percutaneously under ultrasound or fluoroscopic guidance. The lesions had a mean volume of 4 ml (range 2-14 ml). An average of 3 treatments was required (range 1-9). In 4 patients a single treatment was sufficient. For those patients requiring multiple treatments, a mean of 4 treatments were required over an average period of 28 months. The overall response rate was 83% (10/12). Complete resolution was achieved in 4 cases (33%) with a significant reduction in size in a further 6 cases (50%). Larger lesions generally require more treatments than low volume lesions. Two cases recurred despite treatment. One patient suffered minor bleeding following transcutaneous injection. CONCLUSIONS: Injection sclerotherapy using STS foam offers an effective treatment option when managing children presenting with venous malformations in the oral and pharyngeal. A single treatment may be adequate for small lesions but the procedure may be safely repeated until a satisfactory result is obtained.

Successful treatment of isolated subglottic haemangioma with propranolol alone.

Subglottic haemangioma is a rare but potentially life threatening condition which requires intervention. Many different treatments have been described with varying degrees of success and complications. Recently, successful treatment with propranolol has been reported in 11 cases of cutaneous haemangiomas and then in two cases of subglottic haemangiomas with extensive cutaneous lesions in conjunction with other treatment modalities. We describe the successful treatment with propranolol, of a stridulous four-month-old child with a 95% obstructing subglottic haemangioma. This was achieved without the need for tracheostomy or any other surgical intervention, and with no reported side effects. We now believe the new discovery of a dramatic response to propranolol allows treatment in the acute setting and following further study may render surgical treatment of subglottic haemangioma obsolete.

Techniques and outcomes of laryngeal cleft repair: an update to the Great Ormond Street Hospital series.

We present an update to the Great Ormond Street Hospital series of laryngeal clefts, describing a further 35 clefts of Benjamin-Inglis types 1 through 3 treated between 1992 and 2003. Associated congenital anomalies were common. Most type 1 and smaller type 2 clefts were repaired endoscopically, whereas larger clefts were repaired through an anterior approach. Increasing use was made recently of a 3-layer repair with an interposition graft of temporalis fascia. The rates of complication, revision surgery, and death were 54%, 26%, and 6%, respectively. Most of the children are now orally fed, and 9 still have a tracheotomy.

Intrafamilial correlates of overweight and obesity in African-American and Native-American grandparents, parents, and children in rural Oklahoma.

Study objectives were to describe overweight in Native-American and African-American three-generation families and to examine relationships among the individual variables of body mass index (BMI), television hours, and activity levels. Forty-four Native-American and 40 African-American families were recruited from 10 sites through community contacts at health, senior, community, and tribal centers. Ninety percent of parents and grandparents had BMIs above 25.0. Forty-two percent of African-American and 61% of Native-American children had a BMI above the 85th percentile. More than 35% of total energy was from fat. Significant correlations were observed between parent and child BMI and television hours, grandparent and child BMI, and grandparent and parent activity with child television hours. Sedentary caretakers facilitate more television viewing and less activity in children. Dietetics professionals should plan family-friendly daily physical activities, like walking, and diets lower in fat, sugar, and total energy, with higher intakes of fresh fruits and vegetables, whole grains, and low-fat dairy products for children and caretakers.

Long-segment tracheal stenosis: slide tracheoplasty and a multidisciplinary approach improve outcomes and reduce costs.

OBJECTIVE: Long-segment tracheal stenosis is rare, life-threatening, difficult, and expensive to treat. Management remains controversial. A multidisciplinary tracheal team was formed in 2000 to deal with a large number of children with airway problems referred for management. We review the effect of that service, comparing the era before and after the establishment of the multidisciplinary tracheal team. METHODS: From January 1998 through January 2004, 34 patients with long-segment tracheal stenosis (21 patients with cardiovascular anomalies) underwent surgical intervention. Cardiopulmonary bypass was used in all operations. Before the multidisciplinary tracheal team, pericardial patch tracheoplasty with or without an autograft technique was the preferred method of repair. After the multidisciplinary tracheal team, an integrated care plan preferring slide tracheoplasty was initiated, correcting cardiac lesions simultaneously. RESULTS: Before the establishment of the multidisciplinary tracheal team, pericardial patch tracheoplasty was performed in 15 of 19 patients. Twelve patients had a suspended pericardial patch tracheoplasty, 2 (17%) of whom died late after the operation. Of 3 patients who had had a simple unsuspended patch, 2 (67%) died early after the operation. Four patients were operated on with the tracheal autograft technique, 2 (50%) dying early in the postoperative period. After multidisciplinary tracheal team formation, in the era between 2001 and 2004, 15 patients were operated on with slide tracheoplasty, and there were 2 (13%) early postoperative deaths. A significant reduction in cost and duration of stay has been shown both in the intensive care unit and the hospital. CONCLUSION: Our data suggest that a formalized multidisciplinary team approach and a policy of primary slide tracheoplasty are beneficial in the management of children with long-segment tracheal stenosis.

Can we develop a protocol for the safe decannulation of tracheostomies in children less than 18 months old?

Expanding indications for airway and head and neck surgery have led to a number of children under 18 months of age being deemed suitable for decannulation of their tracheostomies. We present four cases to illustrate the particular problems encountered in this age group and suggest modifications to our previously-published decannulation protocol.

The management of congenital tracheal stenosis.

This paper reviews current concepts and results in the management of congenital tracheal stenosis (CTS). Diagnostic options are considered and the requirements for successful management defined. Chief amongst these is a multi-disciplinary approach with individualised patient management. Severe long-segment CTS represents the biggest challenge to clinicians and the worst problems for affected families. Near-death episodes are frequent in affected infants and some cannot be ventilated and require ECMO. Associated cardiovascular anomalies are frequent. Patients require immediate resuscitation and transfer to a specialist unit. After careful assessment, accurate diagnosis and discussion, primary resection and end-to-end repair with a slide technique should always be the first option, with concomitant repair of associated cardiac anomalies. If this is impossible because of the severity of the lesion, some form of patch tracheoplasty will be indicated. Cardiopulmonary bypass is often required. Patches include pericardium, autograft trachea, carotid artery, cartilage, and allograft trachea. Mortality ranges from 0 to 30% in the literature, which largely comprises single-centre long-term experience. Recurrence is common and can be managed by stenting and tracheal homograft implantation. Long-term quality of life of survivors is little reported but seems good. Physiological data are lacking. To improve results, we suggest a treatment algorithm to rationalise care.
