Time is the only treatment necessary in more than 90% of infant cases. In other cases, surgery may be necessary. Most commonly, this involves cutting the aryepiglottic folds to let the supraglottic airway spring open. Trimming of the arytenoid cartilages or the mucosa/ tissue over the arytenoid cartilages can also be performed as part of the supraglottoplasty. Supraglottoplasty can be performed bilaterally (on both the left and right sides at the same time), or be staged where only one side is operated on at a time.

Treatment of gastroesophageal reflux disease can also help in the treatment of laryngomalacia, since gastric contents can cause the back part of the larynx to swell and collapse even further into the airway.

In some cases, a temporary tracheostomy may be necessary.

Laryngomalacia becomes symptomatic after the first few months of life (2–3 months), and the stridor may get louder over the first year, as the child moves air more vigorously. Most of the cases resolve spontaneously and less than 15% of the cases will need surgical intervention. Parents need to be supported and educated about the condition.

If the symptoms are severe enough, treatment may be needed. These range from medical management over mechanical ventilation (both continuous positive airway pressure (CPAP), or bi-level positive airway pressure (BiPAP) to tracheal stenting and surgery.

Surgical techniques include aortopexy, tracheopexy, tracheobronchoplasty, and tracheostomy. The role of the nebulised recombinant human deoxyribonuclease (rhDNase) remains inconclusive.

Management of symptoms for patients within this subgroup of the GERD spectrum is difficult. Once these patients are identified, behavioural and dietary changes are advised. Dietary modifications may include limiting the intake of chocolate, caffeine, acidic food and liquids, gaseous beverages and foods high in fat. Behavioral changes may include weight loss, cessation of smoking, limiting alcohol consumption and avoiding the ingestion of food shortly before bed. Lifestyle changes in children diagnosed with LPR include dietary modifications to avoid foods that will aggravate reflux (e.g., chocolate or acidic and spicy food), altering positioning (e.g., sleeping on your side), modifying the textures of foods (e.g., thickening feeds to heighten awareness of the passing bolus), and eliminating the intake of food before bed.

Proton pump inhibitors (PPIs) are the leading pharmaceutical intervention chosen for the relief and reduction of LPR and are typically recommended for ongoing use twice a day for a period of 3–6 months. PPIs have been shown to be ineffective in very young children and are of uncertain efficacy in older children, for whom their use has been discouraged. While PPIs may provide limited clinical benefits in some adults, there is insufficient evidence to support routine use. Many studies show that PPIs are not more effective than placebos in treating LPR.

When medical management fails, Nissen fundoplication can be offered. However, patients should be advised that surgery may not result in complete elimination of LPR symptoms and even with immediate success, recurrence of symptoms later on is still possible.

One way to assess treatment outcomes for LPR is through the use of voice quality measures. Both subjective and objective measures of voice quality can be used to assess treatment outcomes. Subjective measures include scales such as the Grade, Roughness, Breathiness, Asthenia, Strain Scale (GRBAS); the Reflux Symptom Index; the Voice Handicap Index (VHI); and a voice symptom scale. Objective measures often rely on acoustic parameters such as jitter, shimmer, signal-to-noise ratio, and fundamental frequency, among others. Aerodynamic measures such as vital capacity and maximum phonation time (MPT) have also been used as an objective measure. However, there is not yet a consensus on how best to use the measures or which measures are best to assess treatment outcomes for LPR.

Tracheomalacia is a condition where the cartilage that keeps the airway (trachea) open is soft such that the trachea partly collapses especially during increased airflow. The usual symptom is stridor when a person breathes out.

The trachea normally opens slightly during breathing in and narrows slightly during breathing out. These processes are exaggerated in tracheomalacia, leading to airway collapse on breathing out.

If the condition extends further to the large airways (bronchi) (if there is also bronchomalacia), it is termed tracheobronchomalacia. The same condition can also affect the larynx, which is called laryngomalacia. The term is from "trachea" and the Greek μαλακία, "softening"

There are no treatment to return to its normal functions. However, there are treatments for the different symptoms.

For the Developmental symptoms, Educational intervention and speech therapy beginning in infancy could help to reduce the high risk for motor, cognitive, speech, and language delay

For theSkeletal features, referral to an orthopedist for consideration of surgical release of contractures. In addition,early referral to physical therapy could help increase joint mobility.

Lastly, Thyroid hormone replacement could help out the thyroid dysfunction

Subglottic stenosis is a congenital or acquired narrowing of the subglottic airway. Although it is relatively rare, it is the third most common congenital airway problem (after laryngomalacia and vocal cord paralysis). Subglottic stenosis can present as a life-threatening airway emergency. It is imperative that the otolaryngologist be an expert at dealing with the diagnosis and management of this disorder. Subglottic stenosis can affect both children and adults.

Subglottic stenosis can be of three forms, namely congenital subglottic stenosis, idiopathic subglottic stenosis (ISS) and acquired subglottic stenosis. As the name suggests, congenital subglottic stenosis is a birth defect. Idiopathic subglottic stenosis is a narrowing of the airway due to an unknown cause. Acquired subglottic stenosis generally follows as an after-effect of airway intubation, and in extremely rare cases as a result of gastroesophageal reflux disease (GERD).

Subglottic stenosis is graded according to the Cotton-Meyer classification system from one to four based on the severity of the blockage.

Grade 1 – <50% obstruction

Grade 2 – 51–70% obstruction

Grade 3 – 71–99% obstruction

Grade 4 – no detectable lumen

Treatments to alleviate the symptoms of subglottic stenosis includes a daily dose of steroids such as prednisone, which reduces the inflammation of the area for better breathing. Other medications such as Methotrexate is also being tested by patients but results are pending.

Extraesophageal symptoms result from exposure of the upper aerodigestive tract to gastric contents. This causes a variety of symptoms, including hoarseness, postnasal drip, sore throat, difficulty swallowing, indigestion, chronic cough, wheezing, globus pharyngeus, and chronic throat-clearing. Some people with LPR have heartburn, while others have little to no heartburn as refluxed stomach contents do not remain in the esophagus long enough to irritate the surrounding tissue. Individuals with more severe forms of LPR may experience abrasion of tooth enamel due to intermittent presence of gastric contents in the oral cavity.

Additionally, LPR can cause inflammation in the vocal tract which results in the symptom of dysphonia or hoarseness. Hoarseness is considered to be one of the primary symptoms of LPR and is associated with complaints such as strain, vocal fatigue, muskuloskeletal tension, and hard glottal attacks, all of which can reduce a person's ability to communicate effectively. Moreover, LPR patients may try to compensate for their hoarseness by increasing muscular tension in their vocal tract. This hyper-functional technique adopted in response to the inflammation caused by LPR can lead to a condition called muscle tension dysphonia and may persist even after the hoarseness and inflammation has disappeared. A speech-language pathologist will often need to be involved to help resolve this maladaptive, compensatory pattern through the implementation of voice therapy.

LPR presents as a chronic and intermittent disease in children. LPR in children and infants tends to manifest with a unique set of symptoms. Symptoms seen in children with LPR include a cough, hoarseness, stridor, sore throat, asthma, vomiting, globus sensation, wheezing, aspiration and recurrent pneumonia. Common symptoms of LPR in infants include wheezing, stridor, persistent or recurrent cough, apnea, feeding difficulties, aspiration, regurgitation, and failure to thrive. Moreover, LPR in children is commonly concomitant with laryngeal disorders such as laryngomalacia, subglottic stenosis, and laryngeal papillomatosis.

There are no prospective randomized controlled trials studying therapies for relapsing polychondritis. Evidence for efficacy of treatments is based on case reports and series of small groups of patients.

For mild cases limited to joint pain or arthritis, oral nonsteroidal anti-inflammatory drugs (NSAIDs) may be used. Other treatments typically involve medications to suppress the immune system. Corticosteroids are frequently used for more serious disease. Steroid-sparing medications such as azathioprine or methotrexate may be used to minimize steroid doses and limit the side effects of steroids. For severe disease cyclophosphamide is often given in addition to high dose intravenous steroids.

A vascular ring is a congenital defect in which there is an abnormal formation of the aorta and/or its surrounding blood vessels. The trachea and esophagus are completely encircled and sometimes compressed by a "ring" formed by these vessels, which can lead to breathing and digestive difficulties.

Most often this is because of persistence of the double aortic arch after the second month of fetal life.

Infants with vascular rings typically present before 12 months with respiratory or esophageal symptoms like stridor, wheezing, cough, dysphagia, or difficulty feeding. The stridor improves with neck extension, differentiating from laryngomalacia which is relieved by prone or upright positioning, and will not be relieved with corticosteroids or epinephrine, unlike croup. Diagnosis requires a high degree of clinical suspicion and can be confirmed with barium contrast esophagogram for those with esophageal symptoms, bronchoscopy, or CT or MRI.

Many individuals have mild symptoms, which recur infrequently, while others may have persistent problems that become debilitating or life-threatening.

Genitopatellar syndrome is a rare disorder with characteristic craniofacial features, congenital flexion contractures of the lower limbs, absent or abnormal patellae, urogenital anomalies, and severe psychomotor retardation.

In 2012, it was shown that mutations in the gene KAT6B cause the syndrome.

Fetal warfarin syndrome (dysmorphism due to warfarin, warfarin embryopathy) is a condition associated with administration of warfarin during pregnancy.

Associated conditions include hypoplasia of nasal bridge, laryngomalacia, pectus carinatum, congenital heart defects, ventriculomegaly, agenesis of the corpus callosum, stippled epiphyses, telebrachydactyly, and growth retardation.

It is also known as "DiSaia syndrome". The symptoms are nasal hypoplasia, depressed nasal bridge, deep groove between nostril and nasal tip, stippling of uncalcified epiphyses during first year, mild hypoplasia of nails, shortened fingers, low birth weight, significant intellectual disability, seizures, reduced muscle tone, widely spaced nipples, deafness and feeding difficulty.
