Overview of Facial Reconstruction for Mohs Defect Repairs

Mohs micrographic surgery (MMS) is a special surgical procedure used to treat certain types of skin cancer. These include basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and, in some cases, invasive melanoma. This method is especially common in the US and other western countries due to its effectiveness.

The process of MMS involves precisely mapping out the cancer and examining all its margins under a microscope. This ensures the complete removal of the tumor while leaving as much healthy tissue as possible. Preserving normal tissue is crucial, especially on the face, to maintain function and appearance.

Despite its precision, there can be instances where removing the cancer creates a significant gap in the tissue, also known as a post-excisional defect. This article will explore how to reconstruct facial features such as the forehead, nose, cheek, and mouth area after MMS.

Anatomy and Physiology of Facial Reconstruction for Mohs Defect Repairs

The outer covering of your body, the skin, has three main parts. The epidermis is the outermost layer. The dermis is the middle layer, which contains things such as hair roots, glands, nerves, and small blood vessels. The deepest layer is the hypodermis, which is made up of looser connective tissue and fat.

Your forehead has different parts each with a specific role. The supraorbital nerve, which gives you feeling in the upper part of your nose, forehead, and eyeledis, comes from above your eye socket. Another nerve, the supratrochlear nerve, provides sensation to the middle of your forehead and eyebrow and starts just above your eye socket. Blood reaches your forehead through different arteries, the main ones being the supratrochlear and supraorbital arteries, and the superficial temporal artery. The hair on your forehead grows in a particular direction, which is important to note when having procedures done.

Your nose is structured in a specific way. It has different sections, like the nasal tip (the pointy part of your nose), the dorsum (the top surface), the columella (the part between your nostrils), and the sidewalls (the sides of your nose). Other parts of your nose include the radix (where the nose and forehead meet), and the rhinion (where the hard and soft parts of the nose meet). The skin on your nose has multiple layers and is thicker in some areas than others. There are also several muscles linked with the nose. The structure of your nose is supported by the nasal bone, the septum, and the upper and lower cartilages.

The skin on your cheeks has different sections too. It receives blood from the facial artery and its branches, the infraorbital branch of the internal maxillary artery, and the transverse facial branch of the superficial temporal artery. Ligaments attached to the skin help hold things in place. The facial nerve supplies sensation to the muscles that allow us to show different facial expressions.

Your lips and the skin around your mouth also have a defined structure. The upper lip can be divided into the center section and two side sections, bounded by the creases that run down to the corners of the mouth. The lower lip is separated from the chin by a crease. The coloured, or ‘red’, part of the lip, is known as the vermillion border. The lips composed of a skin layer, a muscle layer (including the orbicularis oris muscle), and a mucous membrane layer. The lips get their blood supply from the superior and inferior labial arteries that generally run deep to the orbicularis oris muscle.

Why do People Need Facial Reconstruction for Mohs Defect Repairs

If you’ve had a skin condition that required removal, like certain types of aggressive skin cancers, you might need a medical procedure called facial reconstruction after Mohs surgery (MMS). This would be necessary if you need a complete closure of the wound left after the skin condition was taken out. Mohs surgery is particular useful for certain aggressive types of Basal Cell Carcinoma (BCC) and Squamous Cell Carcinoma (SCC), large BCC/SCC, recurring BCC/SCC, certain types of melanoma (a serious type of skin cancer), and when lesions (a broad term for any abnormal area of skin) are on aesthetically important places like the face.

Facial reconstruction isn’t just letting the wound heal on its own. It often involves techniques like primary closure (which is sewing the wound shut), skin grafts (transferring skin from one place to another), local flaps (shifting nearby skin and tissue to cover the wound), interpolated flaps (moving skin and tissue with a blood supply from a nearby area to the wound), and free-tissue transfer (moving skin, muscle, and/or fat from one part of the body to another). In some cases, other grafts like cartilage grafts might also be used when extra support is needed for a more satisfactory reconstruction.

It’s important for you to understand your options for reconstruction. Your doctor should explain all these options, so you can decide what you’re comfortable with and what will give you the best result.

When a Person Should Avoid Facial Reconstruction for Mohs Defect Repairs

Sometimes there might be reasons why a person can’t have facial reconstruction surgery after a procedure called Mohs Micrographic Surgery (MMS). They might be too weak or ill to go through the surgery, particularly if they would need to be put to sleep with general anesthesia. Some people don’t want to have more surgery, especially if they would need several operations over time. Finally, the surgery might not be a good option if someone is expecting results that aren’t realistic.

It’s important to talk about these things before you have the MMS and during your first discussion with the doctor about the surgery. There’s not a one-size-fits-all reason why someone can’t have MMS. The best type of reconstruction after MMS might depend on other health conditions a person has and how old they are. Sometimes, the hospital or clinic might not have the right kind of expert or the right equipment to do MMS, which can make it harder for patients to have this procedure.

Equipment used for Facial Reconstruction for Mohs Defect Repairs

When a doctor performs a facial reconstruction after a skin cancer treatment known as Mohs Micrographic Surgery (MMS), they only need a small tray with specific tools. These tools might include:

1. Preparation tools: a pen for marking, local anesthesia for numbing, a cleaning solution known as povidone-iodine, sterile towels, and protection for your eyes like corneal shields.
2. Small straight scissors for careful, precise cuts.
3. Small curved scissors that are good for cutting curved lines and complex shapes.
4. Suture scissors, used to cut stitches.
5. Non-toothed forceps, a kind of tweezers for handling tissues gently.
6. Tissue forceps, like Adson forceps, another type of tweezers for handling tissues.
7. Needle driver, tool to hold and manipulate the needle in suturing or stitching.
8. Number 15 and/or 11 blade, a type of sharp scalpel blade.
9. Penetrating towel clips, which could be useful to pull the skin gently.
10. Sutures, the doctor might use either absorbable sutures (like Vicryl, PDS, or Monocryl) that naturally dissolve in the body, and small non-absorbable sutures (5-0 or 6-0 nylon or Prolene) that need to be removed later.
11. Cautery with a needle-tip, a tool for carefully stopping bleeding.

After the surgery, the doctor will use antibiotic ointment or vaseline to help the wound heal properly and they will cover it with a dressing. This usually includes non-adherent gauze (which won’t stick to your wound) and paper tape.

Who is needed to perform Facial Reconstruction for Mohs Defect Repairs?

A surgeon is a specialized doctor who performs the operation. The surgeon gets help from a surgical assistant, who also has special training in surgical procedures. Another key person during the surgery is the operating room nurse. This person, often known as the circulator, ensures that the surgical team has everything they need and that everything runs smoothly. If you’re put to sleep during the operation, that’s done by an anesthesiologist. This is a doctor who specializes in using medicine to prevent pain and help you stay comfortable during the surgery.

Preparing for Facial Reconstruction for Mohs Defect Repairs

Before any procedure, pictures are typically taken to clearly show the area that needs to be treated, including how large it is and what parts of it are affected, such as the skin, muscle, inside lining of the body (mucosa), firm connective tissue (cartilage), and so on.

It’s also very important that doctors fully explain what the procedure will involve, including its potential risks and benefits, as well as any other possible treatment options. This way, patients are fully aware and can give their permission (known as “informed consent”) for the procedure to happen.

How is Facial Reconstruction for Mohs Defect Repairs performed

Before starting facial reconstruction after Mohs micrographic surgery (MMS), it’s essential to confirm the status of the margin (whether the entire tumor has been removed) first. The reconstruction usually happens on the same day as the surgery but sometimes can take longer, especially for skin or composite grafts. The method of reconstruction depends on different factors like the surgeon’s experience, the size of the defect, the patient’s health and expectations, and the location of the defect. We will now discuss specific considerations for reconstructing areas like forehead, nose, cheek, and the mouth area.

When reconstructing defects of the forehead, it’s essential to avoid distorting the natural hairline and eyebrow. For small defects, the skin can be stitched closed in a line either horizontally or vertically. There are several flaps (ways of moving skin around) available for surgeries where the skin cannot be stitched up directly. There are also other options like tissue expanders or microsurgery for larger defects.

The nose is a prominent feature of the face. When planning a reconstruction, it’s important to keep the natural lines and shapes of the nose in mind. You can stitch up small defects right in the middle or along the side of the nose. For more considerable damage, a flap of skin from elsewhere on the body can be used. If the nose requires more structural support, other flaps, skin grafts, or tissue building can be used. For some cases, additional support or reconstruction may be necessary. Again, there are multiple techniques available, and your surgeon will help you choose the best method.

The main concern when reconstructing the cheek is to avoid pulling down the lower eyelid. There are stitches that are available to provide support to the lower eyelid along with other techniques. You also need to be careful with the side of the mouth to maintain symmetry. You can stitch up small to moderate defects, or you can use flaps of skin if it’s not possible. For large lesions, rotation flaps (a type of skin graft) can be helpful. The cut for the flap should be planned at the junction of the cheek and eyelid to minimize eyelid traction.

Finally, for the mouth area, there’s a risk of the soft tissue shrinking due to a lack of support from underlying tissues. For small defects, the skin can be stitched closed, taking care not to disturb the skin at the edge of the lips. Flaps of skin can also help to repair these defects. For full-thickness defects, the reconstruction options depend on the size and involvement of the oral commissure (corner of the mouth). For smaller defects, the skin can be stitched closed directly, while a skin flap or other advanced techniques can be considered for larger ones.

Possible Complications of Facial Reconstruction for Mohs Defect Repairs

The most typical issues after Mohs micrographic surgery (MMS) can be pain, wound breaking open or “dehiscence”, accumulation of blood outside the vessel or “hematoma”, infection, and failure of the transferred tissue or “flap”. Each area where surgery is done carries different risks in terms of how it might affect looks and function due to the rolls of the nearby structures.

There are specific factors that can make a higher risk of complications more likely after surgical reconstruction of the face for defects caused by MMS, these include:

* being a smoker
* the size of the surgical wound
* defects that are full-thickness or go through an entire body part
* having tissue (or flaps) moved from one part to another along with a cartilage graft
* using composite grafts – pieces of skin and other tissue that are transplanted.

Something to note is that delaying the reconstruction does not lead to a higher risk of infection or flap failure. In fact, it might even lower the chances of these complications occurring.

All surgeries result in some form of a scar. After the operation, attention should be given to this. If a very noticeable scar develops even after generally caring for the wound, there exist several ways to make it look better, but that goes beyond what this article covers.

What Else Should I Know About Facial Reconstruction for Mohs Defect Repairs?

Facial reconstruction is a crucial method used to mend issues with the face after the removal of skin cancer using a technique known as Mohs Micrographic Surgery (MMS). When carrying out facial reconstruction, it’s essential that the patient is properly evaluated. A well-thought-out plan, based on the individual’s anatomy, can result in safe and satisfactory results.

Facial reconstruction for Mohs defect repairs can affect different parts of your face, including your forehead, nose, cheeks, and lips. These areas have specific structures and functions that may be impacted during the reconstruction process. It is important to consider the nerves, blood supply, muscles, and other components of these facial features to ensure successful and effective reconstruction.

There are several reasons why someone might need facial reconstruction for Mohs defect repairs. Some individuals may be too weak or ill to undergo surgery, particularly if they would require general anesthesia. Others may not want to undergo additional surgeries, especially if multiple operations are needed over time. Additionally, facial reconstruction may not be a suitable option if someone has unrealistic expectations for the results. Ultimately, the decision to undergo facial reconstruction after Mohs Micrographic Surgery (MMS) depends on individual circumstances, including other health conditions and age. It is important to discuss these factors with a doctor before undergoing MMS.

You should not get facial reconstruction for Mohs defect repairs if you are too weak or ill to undergo surgery, if you do not want to have multiple surgeries over time, or if you have unrealistic expectations about the results. Additionally, if the hospital or clinic does not have the necessary expertise or equipment for the procedure, it may not be a viable option.

The recovery time for Facial Reconstruction after Mohs Defect Repairs can vary depending on the size of the defect, the location, and the specific technique used for reconstruction. In general, the recovery period can range from a few weeks to several months. It is important for patients to follow post-operative care instructions provided by their surgeon to ensure proper healing and minimize complications.

To prepare for Facial Reconstruction for Mohs Defect Repairs, it is important to have a thorough understanding of the procedure and the different options available. This includes discussing the potential risks and benefits with your doctor and giving informed consent. Additionally, it is crucial to have a comprehensive evaluation of your specific case, taking into account factors such as the size of the defect, your overall health, and your expectations for the outcome.

The complications of Facial Reconstruction for Mohs Defect Repairs include pain, wound dehiscence, hematoma, infection, and flap failure. Factors that can increase the risk of complications include smoking, the size of the surgical wound, full-thickness defects, tissue or flap movement, and the use of composite grafts. Delaying reconstruction does not increase the risk of infection or flap failure. Scarring is also a common outcome of surgery, and additional measures may be taken to improve the appearance of the scar.

There are no specific symptoms mentioned in the text that would require Facial Reconstruction for Mohs Defect Repairs. The text only states that facial reconstruction may be necessary if there is a need for complete closure of the wound left after the removal of a skin condition, such as certain types of aggressive skin cancers. The decision for facial reconstruction would be based on the location and extent of the wound, as well as the desired aesthetic outcome.
