Treatment outcomes in patients with laryngotracheal lesions and compromised airway during and prior to the coronovirus disease 2019 pandemic: a tertiary institution's experience.

OBJECTIVE: This study aimed to compare treatment outcomes in patients with laryngeal and tracheal stenosis treated during and prior to the coronavirus disease 2019 pandemic period. METHOD: Patients treated for laryngotracheal lesions with impending airway compromise during the active pandemic period were matched with those treated for similar lesions in the preceding years in a monocentric tertiary hospital setting. RESULTS: During the pandemic period of 55 days, 31 patients underwent 47 procedures. Seven patients (2 children, 5 adults) had open airway surgery, and one had an operation-specific complication. Twenty-four patients (10 children, 14 adults) underwent 40 endoscopic interventions without any complications. Operation specific results during and prior to the pandemic were comparable. CONCLUSION: The management strategy in patients with laryngotracheal lesions and impending airway compromise should not be altered during periods of risk from coronavirus disease 2019. Avoiding a tracheostomy by performing primary corrective surgery or proceeding with a definitive decannulation would be beneficial in these patients to reduce the risk of contagion.

A new dimension of success in the management of airway disease in children with neurological deficit.

OBJECTIVES: Anomalies of the larynx and trachea can cause respiratory distress in infants and older children. Depending on its nature, degree and extent of the disease invasive open surgery is indicated. Non-airway-related co-morbidities increase the challenges in its treatment. Neurological deficit poses a great challenge as it is associated with hypotonia and causes diminished laryngeal coordination. The definition of success in treatment of laryngotracheal disease has always focused on the post-operative functional outcomes: breathing, voice swallowing. The aim of this study is to describe a new dimension of success in the management of laryngotracheal disease in children with moderate neurological deficit, where the expected functional gain is less than in otherwise healthy children. METHODS: This retrospective observational study includes all patients who have undergone open reconstructive airway surgery between 2012 and 2017. Control patients without neurological deficit and cases with moderate neurological deficit were included. Functional outcome data was obtained from clinical records and two questionnaires were filled in by the parents of the children: one the pediatric voice-handicap index (pVHI) and a quality of life questionnaire. RESULTS: Thirty-two children were included of which ten had moderate neurological deficit. Both groups revealed post-operatively an improvement in the functional outcomes: breathing, voice and swallowing, however, as expected, a trend was observed towards less functional improvement in children with neurological deficit. Both groups reveal a remarkable gain in quality of life (QoL). CONCLUSION: Indicating the QoL to be an unidentified, dimension of success in the management of laryngotracheal disease in children with moderate neurological deficit.

Surgical options in suprastomal collapse-induced severe airway obstruction.

PURPOSE: A single institutions experience with various surgical options in the treatment of severe suprastomal collapse (SSC). METHODS: The study included 18 tracheostomized children with SSC treated between January 2012 and December 2018. Data included: patient demography, initial airway lesions, comorbidities, indication and age at tracheostomy, prior airway surgery, stomal demography, type of surgery, postoperative management, complications and treatment outcomes. RESULTS: Four techniques were used to correct SSC. The surgical choice was dependent on stoma demography and associated airway lesions. Excision was done in eight patients and rib cartilage augmentation in five. Three patients had single stage tracheal resection and anastomosis. Two patients received stomal rigidification and temporary placement of Montgomery T tube. Three patients with anterior rib graft augmentation required additional lateral tracheal wall rigidification. Three patients (two with cartilage augmentation, and one with stomal rigidification) developed minimal granulation tissue in the postoperative period. Complete SSC resolution was seen in all except two patients who had a partial response to the treatment. All patients were successful decannulated and are currently asymptomatic. CONCLUSION: Decannulation failures may be due to severe suprastomal collapse that could be either unique or associated with obstructing laryngotracheal lesions. Therefore, it is essential to select the most appropriate surgical treatment to obtain overall favorable outcomes.

Claviculotracheopexy for complex airway reconstructions.

PURPOSE: Revision surgery for correcting benign laryngotracheal stenosis is challenging and it gets complicated in patients with comorbidities. To improve results in such cases, we describe a new technique of stabilizing the trachea by splinting it to the clavicle on both sides. METHODS: Retrospective case series. RESULTS: Three patients received claviculotracheopexy to maintain their tracheal static. The surgery offers an immediate and optimal support to an unstable trachea. CONCLUSION: Claviculotracheopexy can be used as a complementary procedure in complex airway reconstructions.

Decoding supraglottic stenosis.

OBJECTIVE: Supraglottic stenosis (SPGS) is a rare condition and little is known about its optimal management. Its etiologies are varied and depend on the age group. Here, we review our institution's series of patients and propose treatment strategies for SPGS. METHODS: SPGS patients between 2013 and 2019 were retrospectively reviewed. We recorded their demography, clinical data and endoscopy. The patients were treated with either an endoscopic, open or a combined approach. Subsequently, we reviewed photo and video documents, medical sheets and long-term follow-up charts. RESULTS: The report includes 14 children having a mean age of 5.7 years (range 2 months-13 years). Seven children had undergone prior supraglottoplasty for laryngomalacia, three children had blunt neck trauma and four had iatrogenic plus post-intubation etiology. Five children received endoscopic treatment and are currently symptom free. Four patients received a combined repair with satisfactory results. Five children received an open repair, four of which are decannulated and feed orally without aspiration. Most children in this group required additional endoscopic interventions. CONCLUSION: Post supraglottoplasty stenosis can be treated optimally by an endoscopic approach. More severe supraglottic cicatrical sequelae with posterior glottic involvement may require a combined endoscopic and open approach. Transglottic stenoses with severe grades of multi-level stenoses require an extended cricotracheal resection.

Criticality in tailoring the treatment for tracheoesophageal fistulas in children.

OBJECTIVE: Tracheo-oesophageal fistula (TOF) is a rare pathology. It can be congenital and concurrent with other congenital anomalies such as oesophageal atresia, laryngeal and tracheal agenesis, or it can be acquired. The purpose of this study was to analyse various management strategies and their outcomes in infants and children with TOF and identify potential areas for standardisation of the fistula repair procedures. METHODS: At a single institution, a retrospective analysis of infants and children with congenital or acquired TOF between 2013 and 2019 was performed. Thirteen patients were identified. Data collection included: patient demography, associated congenital anomalies, details of fistula at the time of endoscopy, surgical approach and intra-operative findings, need for additional intervention(s), and outcomes. RESULTS: Thirteen patients underwent endoscopic or open surgeries for correction of TOF. The TOF was congenital in ten patients and acquired in three patients. Eight patients had associated aero-digestive comorbidities, and six patients had systemic comorbidities. Three patients underwent endoscopic procedures and nine patients underwent an open TOF repair. One patient had tracheal agenesis and was not offered any treatment. Two patients required multiple endoscopic interventions for recurrent TOFs. Among four patients with prior tracheostomy, three were decannulated and one awaits decannulation. Conclusion Appropriate case selection and surgical ergonomics are essential for patients with TOF to avoid recurrences. Preoperative endoscopy to obtain precise details regarding associated laryngotracheal lesions and demographics of the fistula is crucial.

Management of severe congenital laryngeal webs - a 12 year review.

OBJECTIVE: The aim of this study was to investigate respiratory and voice outcomes after open surgery for severe congenital laryngeal web. METHODS: Included were all patients treated for severe congenital glottic web (Cohen type 3 and 4) between 2002 and 2014. Demographic data, symptoms, endoscopic findings, type of operation, outcome and complications were analyzed. Open surgery was performed with division of the web and enlargement of the subglottis by a laryngotracheal reconstruction or an extended partial cricotracheal resection. RESULTS: Fourteen patients were included. Information on the pre-operative voice was available in 11 patients. Aphonia was present in 6 patients (55%), dysphonia was severe in 1 (9%), moderate in 2 (18%) and mild in 2 (18%). Median age at operation was 19.3 months. As a first line treatment, laryngotracheal reconstruction was performed in 12 patients, and an extended partial cricotracheal resection in 2. Median follow-up was 9.5 months. All patients were successfully decannulated in a median time of 4 months after first surgery. Voice was improved in 10/11 (91%). Post-operatively, 3 patients (27%) had good voice. Dysphonia was severe in 2 (18%), moderate in 3 (27%) and mild in 3 patients (27%). CONCLUSION: Open surgery for Cohen type 3 and 4 glottic web allowed establishing a patent airway with successful decannulation in all cases. Quality of voice was improved in 91%, however, voice results were variable. In our opinion a delicate operative technique described in the paper is important for optimal voice results.

[Laryngomalacia: principal cause of stridor in infants and small children]. / Laryngomalacie: cause principale de stridor chez le nourrisson et le petit enfant.

Laryngomalacia (LM) is the most common cause of congenital stridor. It is caused by obstruction of the upper airway by collapse of redundant supraglottic tissues during inspiration. In the management of a child with congenital stridor, it is important to rule out other malformations of the upper airway that could mimic or be synchronous with LM. Symptoms of LM are usually mild and disappear spontaneously by 2 years. About 20% of patients with LM may have extreme symptoms (severe stridor, feeding difficulties and growth retardation) requiring treatment by endoscopic surgery (supraglottoplasty), which has an excellent success rate with little risk of recurrence and complications.

Paralyzed neonatal larynx in adduction. Case series, systematic review and analysis.

OBJECTIVE: Bilateral vocal cord abductor paralysis (BVCAbP) is considered a rare cause of stridor in the newborn. The goal of this work is to present a case series and to review systematically the literature on bilateral vocal cord abductor paralysis in the newborn to better characterize the current knowledge on this entity. METHODS: We performed a systematic literature review with Medline (1950-2011). The authors screened all cases of BVCAbP reported and selected those affecting newborns. RESULTS: Out of the 129 articles screened, 16 were included. A total of 69 cases could be retrieved and analyzed. Associated co-morbidities were found in 54% of the patients, most notably malformative conditions (intracranial or other), or a positive perinatal history (trauma/asphyxia, prematurity). Tracheostomy placement was required in 59% of children, and of these 44% were successfully decannulated. In terms of functional outcome full recovery or improvement were seen in 61% of patients. Major underlying co-morbidities affected negatively the functional outcome (p=.004), but not the need for tracheostomy (p=.604) or the decannulation success rate (p=.063). CONCLUSION: BVCAbP in the newborn is a serious cause of airway obstruction. It can be seen either in a context of multisystem anomalies or as an isolated finding. Newborns with major co-morbidities affecting their normal development are more likely to have poor functional outcomes and to remain tracheostomy-dependant.

Tympanosclerosis-how we look at it.

Tympanosclerosis (TS) is a common sequelae of chronic otitis media found in all age groups. Over a period of 3 years, out of 520 surgical cases, 68 (13%) were found to have varying amounts of Tympanosclerotic plaques (TSP) warranting surgical removal. 60% had extension of TSP over the ossicular chain thus affecting its mobility. Deliberate surgical removal of TSP was undertaken for hearing improvement.Systematic and meticulous removal of TSP rather than en-bloc removal has been found to improve the hearing as close to as in, non-tympanosclerotic ear surgery.
