1. Is surgery for polydactyly simply the removal of extra fingers (toes)? This view is wrong. In order to make the hand (foot) function better and reduce post-operative complications, according to the severity of polydactyly, we will remove the extra fingers (toes) and at the same time perform some work on the adjacent fingers (toes) such as joint capsule shaping, tendon reconstruction, joint shaping, osteotomy and orthopedic work to prevent the development of the adjacent fingers (toes) due to abnormal force lines, scar contracture or longitudinal instability. Secondary bending and lateral deviation deformity. 2.Can I have my fingers and toes surgically removed if they are deformed bilaterally or if there are multiple deformities in the fingers and toes at the same time? Whether multiple deformities of the fingers and toes can be removed at the same time depends on the location of the deformity, the severity of the deformity, and the skill of the surgeon. Each finger (toe) has an intrinsic finger (toe) artery on both sides. In principle, both sides of the same finger (toe) cannot be operated on at the same time to avoid postoperative finger (toe) necrosis due to cutting and pulling and simultaneous destruction of bilateral intrinsic finger (toe) arteries. If the hand and foot have multi-part, complex multi-finger (toe) deformity at the same time, the operation time is too long, it is easy to increase the risk of anesthesia and wound infection; the tourniquet time is too long, it is easy to develop osteo-fascial compartment syndrome, etc.; the main surgeon is not experienced enough to perform multi-part multi-finger (toe) deformity surgery at the same time, it is easy to lead to poor surgical results, long operation time and increased surgical risk; simultaneous operation of multiple limb deformities (such as The anesthesia monitoring will be affected if multiple limbs are operated at the same time (such as all four limbs have deformities). 3.Do I have to have general anesthesia for multi-finger (toe) deformity surgery? Why can’t I choose local anesthesia for surgery on the fingers (toes)? First of all, different types of polydactyly require different surgical methods. For example, a redundant finger with a small tip can be surgically removed without anesthesia at full term, while a crab-pincer-like polydactyly requires not only the removal of the polydactyly, but also the restoration of abnormal bone structure force lines, balancing the longitudinal instability of soft tissues, and the appearance of the finger plastic surgery. Anesthesia is divided into general anesthesia and local anesthesia, and general anesthesia is divided into intravenous general anesthesia, static inhalation compound general anesthesia, and intubation general anesthesia. Intravenous general anesthesia and static inhalation compound general anesthesia are used to induce the child to sleep by intravenous drip or (and) inhalation, because this type of anesthesia is shallow and the drug is metabolized quickly, so this type of anesthesia is only suitable for inducing the child to sleep during intubation general anesthesia or for simple surgery of shorter duration. For more complex polydactyly, the surgery involves a wide range of surgical operations, complex surgical operations, and long surgical time, deeper general anesthesia with intubation is required. Children are often fearful when entering the unfamiliar environment of the operating room, and most of them cry under the serious atmosphere of the operating room and are unable to cooperate with the surgery, so general anesthesia is needed to induce the child to sleep before the surgical operation can be performed. The broad sense of local anesthesia (local anesthesia as the people think of it) includes nerve block anesthesia and local anesthesia (referred to as local anesthesia in medical terminology). Local anesthetic is injected near the peripheral nerve trunk, and by blocking the conduction of nerve impulses, the area innervated by that nerve is anesthetized. Nerve block anesthesia is often added intraoperatively in order to relieve postoperative pain in the affected limb, to help deepen the depth of local surgical anesthesia in children under intravenous general anesthesia, and to prevent the child from moving the limb due to surgical pain during surgery because the anesthesia is too shallow, resulting in accidental finger injury or obstructing surgical operations. Local anesthesia (also called local anesthesia in medical terminology) refers to the application of local anesthetics to a part of the body to temporarily block the sensory nerve conduction function. The advantages of local anesthesia include simplicity, safety, the patient can be awake, fewer complications and less impact on the patient’s physiological function. Compared with general anesthesia, local anesthesia has unique advantages in some aspects. Firstly, local anesthesia has no effect on the mind; secondly, local anesthesia can also play the role of postoperative analgesia to a certain extent; in addition, local anesthesia has the advantages of easy operation, safety, less complications, less impact on the patient’s physiological function, blocking various adverse neurological reactions, reducing the stress reaction caused by surgical trauma and quick recovery. However, local anesthesia, with its small anesthetic range and shallow anesthesia, is particularly ineffective for bone and arthroplasty surgery. Local anesthesia and general anesthesia often complement each other in clinical practice, and the two types of anesthesia should not be completely isolated, but should be considered as part of an individualized anesthetic plan for a specific patient. For example, for pediatric, psychiatric or confused patients, local anesthesia alone should not be used to complete the surgery, but must be supplemented with basic anesthesia or general anesthesia; and local anesthesia can also be used as an adjunct to general anesthesia to enhance the anesthetic effect and reduce the amount of general anesthetics. 4.What is the effect of anesthesia on the child? Will it affect the baby’s development? At present, there is no international report on the adverse effects of anesthesia on the child’s body after surgery. However, it is not recommended to carry out deep anesthesia for a long time or several times in a short period of time, because anesthesia itself is an invasive operation and has certain damage to the airway and lungs, and the accumulation of anesthetic drugs in large quantities for a short period of time will also have certain side effects on the body organs. 5.Is the swelling after polydactyly surgery because the surgery was not done properly? What should I do? Swelling is due to local inflammation and poor venous return after surgery, and local or even general swelling can occur in any trauma. According to the different degrees of swelling, we can treat the swelling accordingly. Mild swelling: the local skin of the finger (toe) is less elastic than the surrounding soft tissue and the circumference increases; moderate swelling: the local skin is shiny and the tension is obviously increased; severe swelling: local tension blisters appear. For mild to moderate swelling, the affected limb can be elevated (the height of the affected limb is higher than the position of the heart), while severe swelling requires elevation of the affected limb, moving the fingers, laser physical therapy, and medication according to the actual situation. 6.Can the appearance and function of the fingers (toes) be restored to the same level as those of ordinary people after surgery? Will there be a significant difference in the size of the affected fingers? Whether the appearance and function of the fingers (toes) can be restored to the same level as those of ordinary people after surgery depends mainly on the development of the fingers (toes) and the level of the surgeon. The surgery can improve the growth environment of the affected finger (toe), promote the appearance and functional development, and the gap between the affected finger (toe) and the normal finger (toe) will become smaller and smaller. In addition, surgery can immediately correct the size of the affected finger (toe) through flap design and fascial flap filling. If the size of the affected finger (toe) and the healthy side have a significant difference, one year after surgery can be adjusted again plastic surgery. 7.Is the scar obvious after polydactyly surgery? When should I start using scar removal medication? Surgical trauma will leave scars, which is an inevitable natural law, but scar formation is inversely proportional to age, the younger the age, the smaller the scar, pay attention to cosmetic sutures and tight sutures during surgery, and at the same time, prevent wound infection by strict disinfection before surgery, attention to sterility during surgery, and changing medication after surgery, all of which can effectively reduce scars. In the early stage of scarring (after the wound has healed for two weeks after surgery), the scar can be faded through pressure bandaging, use of scar removal materials and laser treatment.
