We can’t do anything about the length of your scar but sometimes scars are too wide. There are certain areas of the body in certain situations where scars continue to stretch.
If there has been a problem with the healing particularly if some of the scar opened up or in locations such as the back, there is a tendency for the scar to stretch over time. This means that whilst the scar was initially a hairline over time it can widen and this is particularly true in areas where the scar is under tension.
We would need to look at whether there was a reason for the scar to stretch in the first place to see whether we could do anything differently to prevent stretching happening a second time.
Some areas of the body such as the back are so prone to stretching that we would sometimes advise you not to have a scar revision because there is a good likelihood that it could stretch again. However if there is a reason such as the wound not healing properly or dehiscence (the wound opening up), it is more likely that we would recommend a scar revision.
The scar could be excised and a fresh scar created in the same area and we would often use layers of sutures to increase the strength of the closure and reduce the risk of stretching again. However, there is always a risk of recurrence of the stretching.
