Here’s What It Means If You Have A Cavity Between Your Nose And Upper Lip
#1 Cavity between Nose and Upper Lip
The cavity between the nose and upper lip is known as Philtrum. This cavity is formed as it is the connecting point for three different formation points on the human face. This formation phase usually happens during the third or fourth month of pregnancy.
In humans, the Philtrum is bordered by ridges and is also known as inferonasal depression. It is formed at the place where maxillary processes and Naso medial process meets. They usually meet during the embryonic development process. As these processes fail to fuse in any human being, it results in the formation of a cleft lip and often creates a cavity between nose and lip region.
