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

Prolapse of supraglottic tissues produces a variable amount of airway obstruction and inspiratory stridor. A majority of infants have mild disease and are managed expectantly. [scholars.northwestern.edu]
Other characteristics of the stridor may include: The stridor changes with activity. The stridor is usually less noisy when the child is laying on his/her stomach. The stridor gets worse if the infant has an upper respiratory infection. [childrensnational.org]

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]

Eyes
- 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]
Neurologic
- Agitation
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]
It may be noticeable constantly, or only some of the time, and is often worse with feeding, agitation, and when the baby lies on his or her back (rather than on their stomach). [texaschildrens.org]
The stridor tends to be worse with agitation, eating, or lying flat on the back. Laryngomalacia is frequently associated with acid reflux. [columbiadoctors.org]

The stridor is usually aggravated by respiratory tract infections and agitation. 11 Bacterial Tracheitis. [aafp.org]
- Excitement
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]
The stridor is present during different phases of alertness - eating, sleeping, or excitement. The stridor is usually less noisy when the child is laying on his/her stomach. The stridor gets worse if the infant has an upper respiratory infection. [medcentral.org]
In addition, stridor can: Change with activity Be present during eating, sleeping, or excitement Become less noisy when the baby is lying on his or her belly Get worse if your baby has an upper respiratory infection, like a cough or cold Other symptoms [cooperhealth.org]
The stridor is present during different phases of alertness--eating, sleeping, or excitement. The stridor is usually less noisy when the child is laying on his or her stomach. The stridor gets worse if the infant has an upper respiratory infection. [nyhq.org]
- Seizure
Neurologic Disease Neurologic disease is present in 20–45% of infants with laryngomalacia and includes seizure disorder, hypotonia, developmental delay, cerebral palsy, mental retardation, microcephaly, quadriparesis, and Chiari malformation. [hindawi.com]
Workup
This innovative one-page format provides the definition, differential diagnosis, workup and diagnosis, and treatment options for nearly 170 diseases and disorders. [books.google.com]
The workup will begin with a thorough medical history. To follow, a flexible fiberoptic laryngoscopy will be performed safely at your otolaryngologist’s (ENT’s) office. [texaschildrens.org]
If the baby has normal cry, normal weight gain, normal development, and purely inspiratory noise that developed within the first 2 months of life, then no further workup may be necessary. [emedicine.medscape.com]
The findings underline the heterogeneity of childhood respiratory disease and the importance of considering early life factors when performing diagnostic workup. [adc.bmj.com]
Treatment
Supraglottoplasty is the mainstay of surgical treatment; tracheostomy is rarely needed. [scholars.northwestern.edu]
Other available treatment includes stenting the trachea open. This can be done both internally and externally. [virtualpediatrichospital.org]
Finally circulatory collapse may occur or may die of asphyxia or cardiac failure. 100 Treatment Ⅰ°:etiological treatment, antibiotics and corticosteroid. 101 Treatment Ⅱ°:etiological treatment. in case of tumors of the larynx, trauma, bilateral vocal [slideplayer.com]
What are the adverse effects associated with each treatment option? No treatment other than parental reassurance may be necessary. [cancertherapyadvisor.com]
Prognosis
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]
Etiology
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]
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. [icd10coded.com]

Epidemiology[edit] Although this is a congenital lesion, airway sounds typically begin at age 4–6 weeks. Until that age, inspiratory flow rates may not be high enough to generate the sounds. [en.wikipedia.org]
There are several interesting epidemiological points involving Asthma. It seems that inheritance is multifactorial: a child with one affected parent has a 25% risk of developing it; with both parents affected, the risk increases to 50%. [ispub.com]
Pathophysiology
The developmental and functional anatomy of the larynx will be included, with a discussion of the pathophysiology and history of the disorder. Its diagnosis and a résumé of the various treatment strategies, will be presented. [ncbi.nlm.nih.gov]
The exact pathophysiology is still not well understood. Our objective was to investigate whether laryngomalacia is an inflammatory disease, focusing on the possible role of vitamin D. Study Design Case‐control study. [onlinelibrary.wiley.com]
Pathophysiology: Redundant tissue present in the supraglottis collapses to obstruct the airway during inspiration Decreased area of the airway leads to increased resistance to air flow Airway resistance is inversely proportional to the radius of the airway [medicine.uiowa.edu]
Tracheomalacia Pathophysiology – expiratory collapse of the intrathoracic airway, due to defective cartilaginous support. [pedclerk.bsd.uchicago.edu]
Prevention
Extubation should incorporate an effective comprehensive plan to prevent cannot intubate and cannot ventilate situation. [saudija.org]
This finding may open the door to the appropriate prevention, diagnosis, and treatment, especially for moderate to severe laryngomalacia. Level of Evidence 3b Laryngoscope, 130:448–453, 2020 [onlinelibrary.wiley.com]
Prevention Adults must keep small, easily swallowed objects such as coins, beads, and hard, round candies away from young children so that they do not try to swallow them. [healthofchildren.com]
Premedication of patients with laryngomalacia is essential to prevent vagal responses and as an antisialogogue, sedation is to be used judiciously. [ijaweb.org]
While you can’t prevent laryngomalacia, you may be able to help prevent medical emergencies related to the condition. Consider the following strategies: Know what signs to look for when it comes to feeding, weight gain, and breathing. [healthline.com]
