The buccal fat pad can prevent the cheeks from collapsing when sucking milk in infancy, so children's buccal fat bodies are more developed and their faces are always chubby and round.

According to the distribution characteristics of capsule, vascular source and fixed ligament, buccal fat pad is divided into anterior, middle and posterior lobes. The posterior lobe emits buccal process, pterygopalatine process and temporal process to the surrounding space, and each lobe has an independent capsule, which is fixed to the surrounding tissue structure through buccal fat pad, maxillary ligament, posterior zygomatic ligament, medial margin ligament of infraorbital fissure, lateral margin ligament of infraorbital fissure, temporal tendon ligament and buccal muscle ligament.

Each leaf has an independent source of dimension pipe, and a dimension pipe network is formed under the capsule. Buccal fat pad has the functions of filling, sliding, protection and buffering.

The parotid duct, buccal nerve and facial nerve pass through the anterior lobe, which mainly play a protective and lubricating role; Middle lobe degeneration of adults; The posterior lobe is adjacent to the masseter and buccal muscles, which has little effect.

★ Face-lifting with cheek fat pad

The back leaf of the buccal fat pad can be slightly larger than half an egg yolk, or it can be equivalent to the size of my finger, and the sum of the two sides is slightly larger than an egg yolk. The facial contour changes slightly, which is suitable for beauty seekers with high facial requirements. How to check facial subcutaneous fat or buccal fat pad hypertrophy?

Pinch the cheek skin by hand during the examination, and let the patient bite his teeth hard, which is helpful to distinguish whether the local fullness is due to excessive subcutaneous fat or full buccal fat pad. Some doctors call this plump change of buccal fat pad congenital metabolic disorder of buccal fat. Surgical removal of part of buccal fat pad can improve the appearance of cheek. If there is a lot of subcutaneous fat on the face, liposuction can solve the problem, and partial removal of buccal fat pad is the most effective. How to choose the incision of buccal fat pad operation

After general oral surgery, there is no trace on the cheek. Generally, an incision with a length of 1 ~ 2.5 cm is made at1the mucosa opposite to the second molar. Expose the cheek, and use vascular forceps to separate it in the direction of the ear root. At this time, the buccal fat pad is easy to protrude into the incision, open the capsule, and press it under the zygomatic arch outside the mouth with your fingers, and the buccal fat will automatically come out of the incision, and then be clamped, taken out and electrocoagulated, taking care to avoid damaging the oral mucosa. Only prominent fat is removed to prevent damage to important structures and excessive fat removal. Generally, 4 ~ 6 grams of fat can be removed from one side, and both sides can be removed equally. If there is a significant difference in the filling degree between the two sides before operation, unequal length resection can be performed. Mucosal incision can be sutured without suture or with absorbable suture, and suture removal is not suitable after operation. Conservative attitude should be adopted in intraoperative resection. Sometimes only1~ 2g of fat needs to be removed to achieve satisfactory surgical results. In the case of obvious fullness, 4 ~ 5 grams of fat can be removed from one side. Step by step, don't remove all the fat from the incision. Buccal fat is similar to orbital fat. Excessive removal will cause buccal depression, which is difficult to correct. Buccal liposuction can be performed alone or simultaneously with other facial cosmetic operations, such as face and neck rhytidectomy, orthognathic and masseter hypertrophy resection, etc. In this case, buccal liposuction only plays an auxiliary role. When the preauricular incision and facial and neck flap are lifted, the buccal fat pad can be taken out through the extraoral incision. During the operation, buccal fat pad was exposed at the front edge of masseter muscle, which was nearly 65438±0cm at the horizontal line of mouth corner. Excision of buccal fat pad can make zygomatic contour prominent, but it cannot replace zygomatic filling. It is suggested that it should not be performed at the same time as cheekbone filling to avoid overcorrection. You can remove the buccal fat pad first, and then consider the cheekbone filling.
