Congenital upper airway obstruction is a relatively rare but important cause of major respiratory problems in the neonatal period. Vocal cord paralysis is the second most common cause of congenital airway obstruction presenting with neonatal stridor. It is often the reason for the failure of neonates to wean from the respiratory support. A retrospective analysis of medical record review was conducted. There were seven paediatric patients diagnosed with bilateral vocal fold paralysis in the past three years, of which five were recently diagnosed. All patients underwent flexible with/without rigid bronchoscopes to confirm the diagnosis. This case series highlight our experience in managing the problem of bilateral vocal cord paralysis in the paediatric population, with particular emphasis on their clinical presentations, associated complications and both upper and lower airway abnormalities. The management options and outcome of these patients will also be discussed.

PMID: 16898303 MyJurnal

Many studies have shown that tracheobronchial stenting is effective in relieving respiratory distress secondary to major airway obstruction due to lung or oesophageal cancer. A retrospective review on the benefits and complications of self-expandable metallic stent (SEMS) insertion through flexible bronchoscopy for the palliative treatment of upper airway obstruction in University Malaya Medical Centre was performed. Ten patients underwent this procedure. Relief of dyspnoea was immediate following stent insertion in all patients. Stent migration occurred in one patient and three patients had restenosis of the central airway. We conclude that tracheobronchial stenting via flexible bronchoscopy is feasible and safe.

Fulltext The dilemma of a lateral pharyngeal mass causing stridor in a neonate

Dipak RN, Kailesh P, Sherry MJ, Anindya C

Med J Malaysia, 2005 Oct;60(4):520-2.

PMID: 16570723

Neonatal stridor resulting from intrinsic or extrinsic aberration in the upper respiratory tract often poses not only a diagnostic problem, but also a difficult airway and a dilemma as to the necessity / timing of surgical intervention. A 45 day old female child with increasing stridor since birth was managed by emergency intubation and CT scan followed by excision biopsy of the cystic left sided parapharyngeal mass via a transcervical approach. On histopathology, the excised specimen was reported as cystic salivary choristoma.

PMID: 16898313

Indication for pediatric tracheostomy has changed. Upper airway obstruction secondary to infectious disorders is no longer the commonest indication. The aim of this study was to establish data on indications, outcome and complications of pediatric tracheostomy. A retrospective analysis of pediatric tracheostomies carried out between March 2002 to March 2004 was done. Eighteen patients were identified. The commonest indication was prolonged ventilation (94.5%) followed by pulmonary toilet (5.5%). None was performed for upper airway obstruction. Postoperative complications were encountered in six patients (33.3%), the commonest being accidental decannulation notably in children less than six years of age. Twelve patients (66.6%) were successfully decannulated. The mortality rate was 16.6%. All death were non tracheostomy related. The commonest indication for tracheostomy was prolonged ventilation and tracheostomy in children is relatively safe despite complications.

Mandibular distraction osteogenesis for the management of upper airway obstruction in children with micrognathia: a systematic review

Breik O, Tivey D, Umapathysivam K, Anderson P

Int J Oral Maxillofac Surg, 2016 Jun;45(6):769-82.

PMID: 26867668 DOI: 10.1016/j.ijom.2016.01.009

Mandibular distraction osteogenesis (MDO) is increasingly used for neonates and infants with upper airway obstruction secondary to micrognathia. This systematic review was conducted to determine the effectiveness of MDO in the treatment of airway obstruction. The databases searched included PubMed, Embase, Scopus, and grey literature sources. The inclusion criteria were applied to identify studies in children with clinical evidence of micrognathia/Pierre Robin sequence (PRS) who had failed conservative treatments, including both syndromic and non-syndromic patients. Overall 66 studies were included in this review. Primary MDO for the relief of upper airway obstruction was found to be successful at preventing tracheostomy in 95% of cases. Syndromic patients were found to have a four times greater odds of failure compared to those with isolated PRS. The most common causes of failure were previously undiagnosed lower airway obstruction, central apnoea, undiagnosed neurological abnormalities, and the presence of additional cardiovascular co-morbidities. MDO was less effective (81% success rate) at facilitating decannulation of tracheostomy-dependent children (P<0.0001). Failure in these patients was most commonly due to severe preoperative gastro-oesophageal reflux disease, swallowing dysfunction, and tracheostomy-related complications. The failure rate was higher when MDO was performed at an age of ≥24 months. More studies are needed to evaluate the long-term implications of MDO on facial development and long-term complications.

Tracheostomy in patients with cervical rib: a note of caution

Prepageran N, Raman R

Ear Nose Throat J, 2003 Aug;82(8):626-7.

PMID: 14503102

Cervical rib is a congenital phenomenon that usually occurs in association with upper-limb neurovascular symptoms. The presence of a cervical rib displaces the great vessels that cross the thoracic outlet superiorly and proceed into the neck. We report an unusual case of iatrogenic hemorrhage during a tracheostomy in a patient whose right subclavian artery had been displaced by a cervical rib. Our aim is to alert surgeons to the hidden risks of this phenomenon.

Feeding and reflux in children after mandibular distraction osteogenesis for micrognathia: A systematic review

Breik O, Umapathysivam K, Tivey D, Anderson P

Int J Pediatr Otorhinolaryngol, 2016 Jun;85:128-35.

PMID: 27240511 DOI: 10.1016/j.ijporl.2016.03.033

Mandibular distraction osteogenesis (MDO) is becoming increasingly more commonly used as in neonates and infants with upper airway obstruction secondary to micrognathia. A significant number of these children are dependent on nasoenteric feeding or gastrostomies after birth for adequate nutrition and often suffer from gastro-esophageal reflux (GERD).

OBJECTIVE: This analysis is a subset of a larger systematic review. The objective of this study is to determine the effects of MDO on feeding and GERD.

DATA SOURCES: The databases searched included PubMed, Embase, Scopus, Web of Knowledge and grey literature sources.

STUDY SELECTION: The inclusion criterion included studies in children with clinical evidence of micrognathia/Pierre Robin Sequence (PRS) who have failed conservative treatments, including both syndromic (sMicro) and non-syndromic (iPRS) patients. 21 studies relevant to feeding and 4 studies relevant to GERD outcomes were included. All studies included were case series and case reports.

RESULTS: MDO leads to a significant improvement in feeding, with 82% of children feeding exclusively orally after surgery. The overall percentage of children with iPRS who were feeding orally was 93.7% compared with only 72.9% in the sMicro group (p<0.004). A growth decline within the first six weeks after surgery was observed in multiple studies. Overall, out of 70 patients with pre-operative GERD, only four had evidence of GERD after surgery.

CONCLUSIONS: Considering the limitations of this systematic review, this study found that successful relief of airway obstruction by MDO leads to improvement of feeding and improvement in symptoms of GERD in children with upper airway obstruction secondary to micrognathia. Clinicians need to be aware of the risk of growth decline in the initial post-operative period.

Spontaneous sublingual hematoma as a complication of severe hypertension: first report of a case

Prepageran N, Raman R, Ismail SM, Rahman ZA

Ear Nose Throat J, 2002 Aug;81(8):576-8.

PMID: 12199178

We describe what we believe is the first reported case of a sublingual hematoma secondary to severe hypertension. The patient, a 77-year-old woman, experienced a spontaneous hematoma of the floor of the mouth, tongue, and sublingual space that eventually caused an airway obstruction. We performed an emergency tracheostomy under local anesthesia and then evacuated the hematoma through an incision along the floor of the mouth. The patient recovered uneventfully.

Fulltext Nasopharyngeal diffuse large B-cells lymphoma causing acute airway obstruction amid COVID-19 crisis: an anaesthetist's nightmare

Yeap TB, Teah MK, Quay YJJ, Wong MTF

BMJ Case Rep, 2021 Jan 28;14(1).

PMID: 33509897 DOI: 10.1136/bcr-2020-241008

Acute stridor is often an airway emergency. We present a valuable experience handling an elderly woman who was initially treated as COVID-19 positive during the pandemic in November 2020. She needed an urgent tracheostomy due to nasopharyngeal (NP) diffuse large B-cell lymphoma causing acute airway obstruction. Fortunately, 1 hour later, her NP swab real-time PCR test result returned as SARS-CoV-2 negative. This interesting article depicts the importance of adequate preparations when handling potentially infectious patients with anticipated difficult airway and the perioperative issues associated with it.
