Rhinoplasty – Development Of The Human Nose

August 16, 2012 - admin

Comments are off for this post.

The British Association Of Aesthetic Plastic Surgeons has said that more than 4,000 rhinoplasty procedures are performed every year in the UK, making it the fifth most popular cosmetic surgery. While the majority of these rhinoplasty procedures are performed for aesthetic reasons, nose surgery may also be advised to correct functional problems, or restore noses damaged due to injuries. Rhinoplasty can be performed either by cosmetic surgeons, or appropriately trained ENT surgeons.

The shape and size of the nose that an individual is born with, depends on various factors, some of which include heredity, ethnicity and embryologic development.

Embriologic Growth Of The Nose

After about four weeks of gestational development, the neural crest cells (from which the nose develops), begin to migrate from the posterior to the middle of the face. Two symmetrical nasal placodes (from which the olfactory epithelium will develop) begin to grow inferiorly. They are divided by the nasal pits into the medial and the lateral nasal processes. The medial nasal processes then develop into the septum, the philtrum, and the premaxilla, while the lateral processes become the sides of the nose.

A small membrane divides the nose and mouth, into the inferior oral cavity and the superior nasal cavity. As the olfactory pits begin to get deeper, more organs are formed. This includes the choanae, the two holes connecting the nasal cavity, and the nasopharynx. At first, primitive-form choanae are formed, which keep growing to form the secondary, permanent choanae. Generally, after around ten weeks of gestation, the cells separate into muscle, cartilage, and bone.

The normal embryologic development of the nose is extremely vital, as newborn children breathe solely through their nose, for the first six weeks of life. In cases where this early facial embryogenesis does not occur normally, the infant may be born with nasal anomalies, such as nasal clefts, choanal atresia, and polyrrhinia (double nose). Such birth defects can usually be corrected with rhinoplasty. In cases where the child suffers from problems like bilateral choanal atresia, during which abnormal tissue growth blocks the nasal passages, emergency nose surgery may be required to ensure that the child can breathe properly.

In other cases of nasal birth defects, nose surgery may be performed within a few months or years, depending on the case. It is important to note that in cases where functional or reconstructive rhinoplasty is needed, the nose surgery is performed as soon as possible. This is different from aesthetic rhinoplasty, for which the child may be advised to wait until their mid-teens, for their nose to first grow into its final shape.
