If you do double jaw surgery does your septal cartilage gets damaged?
Hello, this is EU Oral& Maxillofacial Surgery. Today we will talk about double jaw surgery affects the nose. A subscriber has left a precious comment!
The question was “When you do double jaw surgery, does your septal cartilage get damaged? If you already used the septal cartilage for rhinoplasty, and the septal cartilage collapses after double jaw surgery, is revision surgery possible?”
The answer to this question goes like this! The area in which double jaw surgery takes place is very close to the nose. The upper jaw will be moved during double jaw surgery, but the upper jaw is connected to the nose. So double haw surgery and the nose have a very close relationship, regarding the direction and how much we moved the upper jaw. And it’s possible that the nose can look different after the surgery.
To start off, the septal cartilage is one of the cartilages that make up the nose. The body consists of hard bones and soft bones. We call soft bones “Cartilage” For example, the ear has a bone but if you touch it, it’s squishy. That means that there are no hard bones, just cartilage. This applies to the nose as well. There is cartilage in the middle of the inside of the nose, that is the septum. And there is some more cartilage on the outer side of the nose as well. So, while doing double jaw surgery, can the septal cartilage inside the nose be protected, and how we can do so?
There are two factors to consider:
Firstly, if you decide to do rhinoplasty later, they will use this septal cartilage. This septal cartilage needs to be well protected in order for it to be used during rhinoplasty later. So when we do upper jaw surgery, we separate the upper jaw and the septal cartilage. In the process of separation, there is a possibility that the septal cartilage will be damaged. If the separation is not done carefully, the septal cartilage can be cut, or torn those are the ways they can become damaged. It needs to be done carefully so that the septal cartilage is not damaged.
Secondly, the reason the septal cartilage can become damaged
depends on the movement of the upper jaw. The upper jaw is advanced or set back
but also moved up or down. If patients have a gummy smile, it’s caused because the upper jaw
bone is too long. When we reduce the length of the overgrown bone, the whole
jaw moves up as a whole. The upper jaw bone and the septal cartilage are touching.
So when the upper jaw moves up, the area of overlap between the upper jaw bone
and septal cartilage is increased. In these cases, if you do not reduce the
length of the septal cartilage to the amount that the upper jaw bone has been
reduced, the septal cartilage can become bent later. Because the space is now
smaller and the septal cartilage has nowhere to go. So in this case, the septal
cartilage is cut, but as that is done, it can be damaged. At our clinic, when the
upper jaw length has been reduced, we retain the septal cartilage without damaging
it, and we file the area in which the septal cartilage makes contact with the upper
jaw. When you do that, even if the upper jaw bone and the septal cartilage touch,
there is some space that was reserved for the septal cartilage, and we can
prevent the septal cartilage from bending.
Today, we spoke about double jaw surgery and the septal cartilage, double jaw surgery, and the nose, but there are certain instances when the septal cartilage cannot be preserved. However, if the surgeon performing double jaw surgery has a good understanding of the anatomy of the nose, the importance of the septal cartilage, and how the septal cartilage may be used later, then they will perform the surgery to maintain the septal cartilage’s integrity as much as possible.
So if you gave questions regarding the septal cartilage, or
if you plan on getting rhinoplasty later, it’s a good idea to bring it up
during your consultation with your doctor at EU Oral & Maxillofacial
surgery.
