Abstract There is at present, very little information on congenital laryngomalacia in the anaesthetic literature. [ncbi.nlm.nih.gov]

• Crying

  What causes abnormal cry in newborns? An abnormal cry in newborns has many possible causes. They can be broadly grouped into congenital or neurologic causes. [voicefoundation.org]

  The stridor is of variable intensity and is aggravated with crying, feeding, or other periods of excitement or activity. Stridor is also worse when patients lie on their back with their head flexed. Patients are acyanotic with a normal cry. [radiologykey.com]

  In unilateral vocal cord paralysis, the infant's cry is weak and feeble; however, there is usually no respiratory distress. [aafp.org]

• Feeding Difficulties

  Parents may report that the stridor is increased when the child is: Supine Feeding Agitated Crying Infants may present with feeding difficulties such as: Regurgitation, coughing, choking, and slow feedings. [medicine.uiowa.edu]

  This severe form presents as persistent sternal recession, feeding difficulties, and failure to thrive, progressing to apnoeic attacks, cor pulmonale and eventually death. [ncbi.nlm.nih.gov]

  difficulties, swallowing dysfunction, failure to thrive, and respiratory distress. [orpha.net]

  There is no significant airway obstruction, no feeding difficulties, or other symptoms associated with laryngomalacia. The noisy breathing is annoying to caregivers, but does not cause other health care problems. [childrenshospital.vanderbilt.org]

• Surgical Procedure

  If the baby is having moderate-severe stridor, and is having difficulties with feeding and/or sleep, a surgical procedure called supraglottoplasty may be recommended. [stanfordchildrens.org]

  Supraglottoplasty ( Fig. 31.2A, B ) encompasses any surgical procedure to modify flaccid obstructing supraglottic structures. The position and extent of the surgical excision is adapted to fit the individual patient’s anomaly. [entokey.com]

• Weight Loss

  loss, especially in infants. [nationwidechildrens.org]

• Developmental Delay

  Severe laryngomalacia also has continual stridor and increased work of breathing, accompanied by respiratory failure requiring oxygen or airway support, developmental delay and/or failure to thrive. [pedclerk.bsd.uchicago.edu]

  In more severe forms, upper airway obstruction, cyanotic spells, feeding difficulties, failure to thrive, cor pulmonale and developmental delay occur. [ijaweb.org]

  Other causes may be related to weak muscle tone or developmental delays. [chw.org]

  Treatment beyond 12-18 months is rare and primarily associated with other congenital anomalies or developmental delays. What is the evidence? Gandhi, S, Thekedar, P, Mishra, P. [cancertherapyadvisor.com]

  LM is rarely associated with dyspnea or difficulty swallowing. Pathology LM appears to be related to flaccidity and incoordination of the soft tissue and cartilages of the supraglottic larynx. The exact cause of LM is currently under debate. [radiologykey.com]

  Presenting symptoms of dyspnea or accessory muscle use, feeding difficulties, apnea, cyanosis, oxygen desaturation, and failure to thrive were significantly associated with the requirement for operative intervention (all p values less than 0.02). [ncbi.nlm.nih.gov]

  The patient had respiratory distress and difficulties in breast-feeding and dyspnea. New fiberoptic laryngoscopy was performed confirming moderate laryngomalacia and supraglottic cyst. [thieme-connect.com]

• Prolapse

  Laryngomalacia is due to the dynamic prolapse of supraglottic tissues into the airway during inspiration. Prolapse of supraglottic tissues produces a variable amount of airway obstruction and inspiratory stridor. [scholars.northwestern.edu]

  OBJECTIVES/HYPOTHESIS: Laryngomalacia is an enigmatic disease in which laryngeal tone is weak, resulting in dynamic prolapse of tissue into the larynx. [ncbi.nlm.nih.gov]

  Some authors feel certain anatomic abnormalities predispose patients to develop LM, including (1) an elongated epiglottis that curls upon itself (omega-shaped epiglottis), (2) fore-shortened aryepiglottic folds, and (3) bulky arytenoids, which tend to prolapse [radiologykey.com]

  The severity of the physical findings are classified as: Mild – Prolapse of the arytenoid and cuneiform cartilages and/or overlying mucosa during inspiration Moderate – Prolapse of the arytenoids and aryepiglottic folds during inspiration Severe – Prolapse [cancertherapyadvisor.com]

  However, prolapse of supraglottic tissues into the laryngeal inlet during inspiration may also be the cause. The epiglottis, aryepiglottic folds and corniculate mounds of the arytenoids may be involved 1. [radiopaedia.org]

• Agitation

Conclusion: In most children, the prognosis is favorable, as airway obstruction is not severe, and the symptoms improve in patients younger than 2 years. [thieme-connect.com]

Treatment and prognosis Treatment is largely supportive since most children show spontaneous resolution after 12-24 months. When associated gastro-esophageal reflux disease is present, that should be treated. [radiopaedia.org]

Aim: The aim of this study was to assess clinical presentation, management and prognosis of infants and children suffering from laryngomalacia presented to our department in the period of 5 years. [nature.com]

The long-term prognosis is good as these children outgrow their problem. [virtualpediatrichospital.org]

The goal of this study was to elucidate the etiology of decreased laryngeal tone through evaluating the sensorimotor integrative function of the larynx. [ncbi.nlm.nih.gov]
