In the early stage after the operation on the nasal floor, it is true that the expression will be stiff because of swelling, but this situation will gradually improve with recovery. Generally, after 1 month, you can try to restore normal expression according to your personal situation, and you can realize freedom of expression after 3~6 months.
Of course, the premise is that the operation is completed by an experienced doctor under the correct operation, otherwise you may become a "plastic beauty" who can only maintain beauty with a straight face.
1. Expression muscle injury
This situation is common in implanting nasal basal prosthesis through oral incision. If the doctor is rude or unfamiliar with the anatomy of this area, it may damage the orbicularis oris muscle.
The orbicularis oris muscle is one of the important facial muscles in the lower part, and its main function is to maintain the normal shape and movement of the upper and lower lips. Its structure is complex and consists of multiple layers of muscle fibers. The orbicularis oris muscle in the middle layer also includes zygomatic major muscle, zygomatic minor muscle, levator muscle, levator muscle, levator muscle, levator muscle and some muscle bundles of levator muscle.
If the orbicularis oris muscle is seriously damaged, you will not only be unable to laugh freely, pout and whistle, or even suck, chew and talk.
2. Changes of facial expression muscle trajectory
Our facial tissues are hierarchical, from top to bottom are skin, subcutaneous tissue, superficial muscle aponeurosis-expression muscle system, deep muscle and bone. There is a natural gap between periosteum and deep muscle. Here, the holiday body has little influence on the soft tissue structure, and basically does not hinder the normal contraction and stretching of the expression muscles.
However, if the placement level is too shallow or the prosthesis is carved too thick, the prosthesis may spread the soft tissue covering it, change the position and original motion track of the expression muscle, and affect the expression.
There is a risk of injury to orbicularis oris muscle by filling the nasal floor with an intraoral incision, so I usually make a through incision on the lateral edge of the nostril, make a subperiosteal separation on the surface of the upper alveolar bone, and then implant a prosthesis. On the one hand, intranasal incision can effectively prevent the prosthesis from shifting (see: Will the prosthesis shift after nasal bottom filling? Can titanium nails be avoided? How to choose a surgical incision); On the other hand, the operation of intranasal incision does not need to peel off the orbicularis oris muscle, which can protect the integrity of the orbicularis oris muscle system and fundamentally avoid the problem of stiff expression caused by the injury of orbicularis oris muscle.
In addition, in order to reduce the influence on the expression muscles, I pay great attention to controlling the thickness of the prosthesis. I may be a "conservative" compared with doctors who are easy to pad 8 or 9mm thick.
You may ask, if the prosthesis is thin, will the Lamian Noodles effect be compromised? Will you be lonely?
number
As a rhinoplasty surgeon, I usually do nasal basal filling and rhinoplasty together. Nasal bottom filling can provide a natural transition for the connection between nose and face, and avoid the abrupt "rising from the ground" after rhinoplasty.
This is because, in the process of constructing the nasal tip bracket, I lifted the soft tissue around the nasal ridge, the base of the nasal columella and the soft tissue of the upper lip, which raised the base of the nasal columella, that is to say, I shaped the tip of the nose and made the base of the alar fuller.
Therefore, the three-dimensional plane is not only determined by the nasal bottom filling, but the result of the joint action of nasal columella support+nasal tip elevation+nasal bottom filling. Therefore, Lamian Noodles can be effectively centered without placing an excessively thick nasal prosthesis.
