Ankyloglossia with deviation of the epiglottis and larynx
Summary
Ankyloglossia, or tongue-tie, in infants can cause breathing issues and physical abnormalities. Surgical correction improved infant health and oxygen saturation levels.
Area of Science:
- Pediatrics
- Otolaryngology
- Genetics
Background:
- Ankyloglossia (tongue-tie) is often associated with epiglottis and larynx displacement in infants.
- Infants may present with dyspnea, skin and hair abnormalities, and distinctive facial features.
- These symptoms can mimic those preceding sudden infant death syndrome (SIDS).
Purpose of the Study:
- To investigate the association between ankyloglossia and related anatomical abnormalities.
- To evaluate the clinical presentation and impact on infant well-being.
- To assess the effect of surgical intervention on infant health and physiological parameters.
Main Methods:
- Clinical observation of infants with ankyloglossia and associated symptoms.
- Measurement of arterial oxygen percent saturation (SaO2) during sleep, suckling, and wakefulness.
- Evaluation of clinical outcomes following surgical correction of ankyloglossia and laryngeal/epiglottic deviation.
Main Results:
- Observed consistent displacement of the epiglottis and larynx in infants with ankyloglossia.
- Documented various symptoms including dyspnea, skin/hair issues, and specific facial characteristics.
- Measured unstable and slightly low SaO2 levels across different infant states.
- Demonstrated significant improvement in clinical signs and SaO2 stabilization post-surgery.
Conclusions:
- Ankyloglossia, coupled with epiglottis and larynx displacement, presents a distinct clinical syndrome in infants.
- Early recognition and surgical intervention can effectively resolve associated respiratory and physiological disturbances.
- This condition warrants consideration in the differential diagnosis of infants with unexplained respiratory compromise or SIDS-like symptoms.

01:12The Hyoid Bone
The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...
01:20Pharynx
The pharynx, a tubular structure framed by skeletal muscle and lined with mucous membrane, extends continuously from the nasal cavities. It is segmented into three major areas: the nasopharynx, oropharynx, and laryngopharynx.
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...

01:21Larynx
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...

01:23Chronic Pharyngitis
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

01:30Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway interventions are...
01:27Esophageal Achalasia
Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
