Sliding Genioplasty
Procedure Detail
This procedure is usually performed through an intra-oral incision. During a sliding genioplasty a small piece of the bottom part of the chin bone is cut away form the rest of the jaw using a very small saw and then repositioned to better cosmetic position before finally being fixed into its new position with very small titanium plates and screws. Unlike chin augmentations using chin implants, the surgery corrects and amends the bone structure, so the result is permanent.

A better option for more severe receding chins caused by bone loss. backward retraction or under-development of the chin; correct asymmetrical chins

FAQ 常见问答题
Genioplasty is a form of cosmetic surgery that involves repositioning or reshaping the chin to improve facial harmony. Surgeons use genioplasty or chin repositioning surgery to correct the following problems:
• receding chins, or retrogenia
• overly large or extended chins
• chins that are too short or too tall
• misaligned or asymmetrical chins
• abnormal dental bite
果下巴后缩并不十分明显,仅在突度上欠缺一点,即不够翘,那么仅使用假体填充就可以解决问题;但如果下巴同时存在短小、后缩的问题,或后缩的比较严重,侧面看嘴比较突,上下嘴唇皆超出鼻尖和下巴的连线,甚至在自然闭嘴状态下,下巴肌肉紧张,那么需要通过下巴截骨术,才能从根本上解决问题。
People may need to spend around 2 nights in the hospital after a sliding genioplasty procedure.
During this time, their surgeon and nurses will monitor their recovery, looking for signs of infection or other complications.
Before they discharge the individual, a surgeon or nurse will go over postoperative care instructions with them.
These may include:
• dosage and timing for taking oral antibiotics
• tips for managing pain and swelling
• how to rinse the mouth with water or oral antiseptic
• how to remove and replace wound dressings
• switching to liquid or soft food for the first few days
• avoiding strenuous activity for 3–4 weeks
前移量一般为7-8mm,后缩较严重的患者可达到10mm左右;如果术后出现骨性的台阶,经过后期的骨改建,可慢慢变平滑。
The recovery period after a sliding genioplasty is NO longer than chin implant placement. Expect the recovery to take between two and three weeks. Normally, patients are able to return to work seven to ten days after surgery.
一般来说,术后经过2-3周可以基本消肿,3-6个月左右基本恢复正常。
Compared to many other cosmetic surgery procedures, however, a sliding genioplasty is relatively low risk. It is important for patients to understand that every surgical procedure has its own complications and risks. However, if a patient is assessed properly before the surgery and postoperative care is given adequately these risks can be eliminated or reduced
短期内可能会有嘴唇、下巴麻木的感觉,术后会逐渐恢复,并在3-6个月左右基本恢复正常;可以在术后半年内,每日温敷下巴,以促进敏感度的恢复。
There are two types of genioplasty procedures — sliding genioplasty and implant augmentation.
The choice of which procedure to use depends on various factors, including the extent of chin augmentation a person requires, the surgeon’s training and experience, and individual preferences.
Genioplasty can offer numerous benefits for people who are concerned about the appearance of their chin.
The procedure can enhance the overall look of the face by altering the position and size of the chin to complement better the other facial features, such as the forehead, cheeks, and nose.
下巴截骨术,若操作不当,可能出现:1.嘴型或表情改变;2.暂时性下巴麻木;3.下巴线凹陷或落差;4.下唇闭合困难等;因此,手术一定要选择正规的机构进行,才能避免风险的发生。
