What is another term for the piriform aperture?

Anatomical terminology The piriform aperture, pyriform aperture, or anterior nasal aperture, is a pear-shaped opening in the human skull.

What causes pyriform aperture stenosis?

Congenital nasal pyriform aperture stenosis (CNPAS) is an unusual cause of upper airway obstruction that may happen because of respiratory distress, cyclic cyanosis or feeding problems. Bony overgrowth of maxillary nasal process sounds responsible for this deformity.

What is nasal pyriform aperture stenosis?

Congenital nasal pyriform aperture stenosis is defined as a narrowing of the bilateral nasal cavity at the level of the pyriform aperture due to medial positioning or overgrowth of the maxillary process.

What is the nasal septum made of?

The Septum. The nasal septum is the key midline support structure of the nose and is composed of the quadrilateral cartilage, perpendicular plate of the ethmoid bone, and vomer bone (Figure 6-4). The anterior septal cartilage develops as the unossified portion of the perpendicular plate of the ethmoid.

What is nasal bone?

The nasal bones are two small oblong bones, varying in size and form in different individuals; they are placed side by side at the middle and upper part of the face and by their junction, form the bridge of the upper one third of the nose.

Where is the middle nasal concha?

The middle nasal concha consists of the medial surface of the labyrinth of ethmoid which is a thin basal lamella that descends from the undersurface of the cribriform plate and ends in a free, convoluted margin.

How is Choanal atresia diagnosed?

The clinical suspicion of choanal atresia can be confirmed by examination with a flexible nasal endoscope in a newborn with proper preparation, such as nasal decongestion and mucous suctioning, allowing direct visualization of the possible obstruction in the nasal passage.

What is the Pyriform?

The pyriform sinus (also spelled piriform sinus and also known as the pyriform recess, pyriform fossa, and smuggler’s fossa) is the pear-shaped subsite of the hypopharynx located posterolaterally to either side of the laryngeal opening.

What is nasal valve?

The nasal valve is the narrow, internal area of the nose located in the middle to the lower part of the nose that limits airflow. This area can be affected by collapse or narrowing that we call stenosis. When it collapses or becomes narrower it can lead to many problems affecting your breathing.

Can you fix deviated septum without surgery?

If your nasal septum is deviated, surgery provides the most lasting and effective solution. However, many people try other treatments and get sufficient relief without the need for surgery. Nasal obstruction due to a deviated septum is often made worse by allergies or infections.

How far back does your septum go?

The nasal septum is the internal tissue that separates the nose into two parts. It is a supporting structure to the lower two thirds of the nose and lies midway between the nostrils, and divides the nose into two broadly equal, symmetrical halves. It extends about 8cm back from the opening of the nostrils.

Is the piriform aperture a heart shaped opening?

Description. The anterior nasal aperture (piriform or pyriform aperture) is a heart- or pear-shaped opening it the skull. Its long axis is vertical, and narrow end upward; in the recent state it is much contracted by the lateral nasal cartilage and alar cartilages of the nose. It is bounded above by the inferior borders of the nasal bones;
