Potential Risks and Complications of Plastic Surgery

Dr Michael Kernohan will cover your plastic surgery risks and possible complications of surgery in detail during your consultation as part of your informed consent process. He will also do everything possible to manage and reduce your risks, however, surgical complications can still occur.

Surgery is a partnership effort between a surgeon and a patient – please do everything you can to get a great result. Follow instructions, rest, heal and allow plenty of time for recovery.

Risks and complications of surgery

Dr Michael Kernohan will discuss the risks and potential complications associated with plastic surgery as part of the informed consent process.

Surgery is a collaborative effort between the surgeon and the patient. To achieve the best possible outcome, it’s crucial that you actively participate by following Dr Kernohan’s instructions closely. This includes getting ample rest, maintaining a healthy diet, and allowing sufficient time for recovery to promote optimal healing. Above all, refrain from smoking, as it significantly increases the risks.

9 things you can do to minimise your risks and potential complications of surgery

  1. Quit smoking entirely throughout the entire surgical journey, with special emphasis on the periods before and after surgery.
  2. Thoroughly read all your surgical documents and strictly adhere to your surgeon’s instructions. Rest and give yourself ample time to heal. Wear compression garments as directed and avoid removing bandages or touching the incision site until it has properly healed.
  3. Provide accurate and honest information about all medications, supplements, vitamins, and even illicit drugs you are currently taking. Inform both Dr Kernohan and your anesthetist about these substances.
  4. When providing your medical history, be specific about any past difficulties you’ve had with surgery, anesthesia, hospital visits, or healing. It’s crucial to be honest and detailed, particularly regarding any allergic reactions.
  5. Prior to surgery, ensure you thoroughly wash your body to minimise skin bacteria and reduce the risk of infection.
  6. Being in good physical health before surgery can contribute to smoother recovery and improve the final results.
  7. Achieving successful surgical outcomes requires realistic surgical goals, reasonable patient expectations, and a comprehensive understanding of the potential risks of plastic surgery.
  8. Prepare in advance for a restful recovery by shopping for necessities, arranging for support, and avoiding stress and strain.
  9. Follow all medical instructions diligently, especially during the recovery period.

Risks of surgery and potential complications that may apply to any surgical procedure:

General Risks Associated with Surgery:

  • Postoperative infection
  • Bleeding or hematoma
  • Poor scarring, including keloid scars
  • Blood clots in legs or lungs
  • Revision surgery needed to correct or improve the outcome

Specific Risks of Surgery:

  1. General Anesthesia: While anesthesia is generally safe, complications can occur. These range from minor issues like bruising at the injection site or a sore throat from the anesthesia tube to more serious problems like allergic reactions, which may necessitate stopping the surgery and extended hospital stays. If you have had any previous difficulties with surgery, anesthesia, or heart problems, inform your anesthetist.
  2. Pain: Minor post-operative pain may occur, and pain medication will be provided. In case of severe pain, contact Dr Kernohan’s office or the hospital immediately.
  3. Numbness/Nerve Damage: Sensory nerves may be damaged during surgery, leading to temporary numbness in the surgical area. Normal sensory feelings should return after a short period, but there is a risk of more permanent nerve damage.
  4. Internal Bleeding – Hematoma: While all known bleeding points are controlled during surgery, there is a possibility that a blood vessel starts bleeding after wound closure. Severe cases may require a return to the operating theatre for correction.
  5. Fluid Build-Up – Seroma: Following surgery, fluid may accumulate near the surgical site. If this occurs, a visit to the operating theatre or procedure room may be necessary to remove it.
  1. Infection: Infections can occur after surgery, despite precautions taken to maintain a sterile environment. Symptoms of infection include increased pain, redness, swelling, and discharge from the surgical site. Antibiotics may be prescribed to treat the infection, and in severe cases, additional procedures may be required to drain the infected area.
  2. Poor Wound Healing: Some individuals may experience delayed wound healing or poor scar formation. Factors that can contribute to this include poor blood circulation, smoking, certain medical conditions, and inadequate post-operative care. Following Dr Kernohan’s instructions for wound care and maintaining a healthy lifestyle can help promote optimal healing.
  3. Scarring: Scarring is an inherent part of any surgical procedure. While efforts are made to minimise visible scarring and place incisions in inconspicuous locations, individual healing and skin characteristics can influence the final appearance of scars. In some cases, scar revision procedures may be necessary to improve the appearance of scars.
  4. Unsatisfactory Results: Despite the best efforts of the surgeon, there is a possibility that the surgical results may not meet your expectations. It’s important to have realistic expectations and communicate openly with Dr Kernohan about your desired outcomes. In some cases, additional procedures or revisions may be necessary to achieve the desired results.
  5. Blood Clots: Surgery can increase the risk of blood clot formation, particularly in the legs (deep vein thrombosis) or lungs (pulmonary embolism). Steps are taken to minimise this risk, such as early mobilisation, compression stockings, and blood-thinning medications in some cases. Inform Dr Kernohan if you have a history of blood clots or if you are taking any medications that affect blood clotting.
  6. Anesthesia-related Complications: Although rare, complications related to anesthesia can occur, including allergic reactions, respiratory problems, and adverse reactions to medications. Your anesthesiologist will evaluate your medical history and take appropriate measures to minimise these risks.

  1. Nerve Damage: During surgery, there is a risk of damage to surrounding nerves, which can lead to temporary or permanent numbness, tingling, or loss of sensation in the treated area. Nerve damage can affect both motor and sensory functions and may require additional treatment or rehabilitation.
  2. Hematoma: A hematoma is a collection of blood that can accumulate under the skin following surgery. It can cause swelling, pain, and bruising. Small hematomas may resolve on their own, but larger ones may require drainage to prevent infection and promote healing.
  3. Seroma: Similar to a hematoma, a seroma is a collection of fluid that can accumulate under the skin after surgery. It may cause swelling, pain, and a sensation of fluid movement. Small seromas may resolve spontaneously, but larger ones may need to be drained to aid in healing.
  4. Adverse Reaction to Implants: If you are undergoing a procedure that involves the use of implants, such as breast augmentation or buttock augmentation, there is a risk of adverse reactions to the implants. This can include infection, implant rupture or leakage, capsular contracture (scar tissue around the implant), and changes in the shape or position of the implant.
  5. Changes in Sensation or Function: Depending on the type and extent of the surgery, there may be temporary or permanent changes in sensation, function, or range of motion in the treated area. This can include limitations in movement, muscle weakness, or altered sensory perception. Physical therapy or rehabilitation may be necessary to aid in recovery.
  6. Psychological Impact: Undergoing plastic surgery can have psychological effects, especially if the results do not meet your expectations or if you have unrealistic expectations. It’s important to have a thorough discussion with Dr Kernohan about your motivations, goals, and expected outcomes to ensure that you have a realistic understanding of what can be achieved.
  7. Allergic Reactions: Some individuals may have allergic reactions to certain medications, anesthesia, or materials used during surgery, such as sutures or implant materials. It’s crucial to inform Dr Kernohan about any known allergies or previous adverse reactions to minimise the risk of allergic complications.

  1. Scarring: Plastic surgery involves incisions, and as a result, scarring is a common outcome. While surgeons try to minimise carring by placing incisions strategically and using techniques to promote better healing, individual factors such as genetics and the body’s response to surgery can affect the appearance of scars. Some people may develop thick, raised, or keloid scars, which may require additional treatments like scar revision or laser therapy.
  2. Skin Discoloration: In some cases, changes in skin pigmentation can occur after plastic surgery. This can manifest as hyperpigmentation (darkening of the skin) or hypopigmentation (lightening of the skin). Skin discolouration can be temporary or permanent and may require additional treatments to address.
  3. Unsatisfactory Results: There is a possibility that the outcome of the surgery may not meet your expectations. Plastic surgery results can be influenced by various factors, including individual anatomy, healing processes, and surgical techniques. It’s important to have realistic expectations and to communicate openly with your surgeon about your desired outcomes to ensure you have a clear understanding of what can be achieved.
  4. Revision Surgery: In some cases, additional procedures may be necessary to achieve the desired results or address complications. Revision surgery can be more complex and may involve additional risks compared to the initial surgery. It’s important to discuss the potential need for revision surgery with your surgeon and understand the associated risks.
  5. Emotional and Psychological Effects: Undergoing plastic surgery can have emotional and psychological impacts, both positive and negative. While it can enhance self-confidence and improve body image for many individuals, it’s essential to consider the psychological aspects of the procedure. Unrealistic expectations, body dysmorphic disorder, or dissatisfaction with the results can lead to emotional distress. It’s crucial to have a support system in place and consider counselling or therapy if needed.
  6. Anesthesia Complications: Plastic surgery often requires the use of anesthesia, which carries its own set of risks. These can include adverse reactions, medication interactions, breathing difficulties, or complications related to anesthesia administration. An anesthesiologist or a qualified healthcare professional will monitor you closely during the procedure to ensure your safety.
  7. Infection: As with any surgical procedure, there is a risk of developing an infection. Surgeons take precautions, such as using sterile techniques and prescribing antibiotics, but infections can still occur. Signs of infection include increased pain, redness, swelling, warmth, or discharge from the surgical site. Prompt treatment with antibiotics is essential to prevent complications.
