Spring Removal Surgery Recovery: What to Expect

The thought of your baby needing a second surgery is often the biggest concern for parents considering spring-mediated cranioplasty (SMC) for craniosynostosis (a condition where the bones of the skull fuse too early). The good news is that the second surgery to remove the springs is vastly different from the first. It is a very short, minor outpatient procedure requiring minimal recovery time ^[1][2]. While it does mean your baby will need a second round of anesthesia, the removal itself is minimally invasive and much less traumatic than the initial placement ^[1].

What Happens on Surgery Day?

Your baby’s surgical team will typically schedule the removal about three to five months after the springs were first put in, giving the skull enough time to expand and the bone gaps to begin healing ^[1][3].

Because general anesthesia is required, standard pre-surgery fasting rules will apply, which means your baby will not be able to eat or drink for several hours before the procedure ^[1]. During the surgery, the surgeon will reopen the exact same small incisions that were made during the first surgery, which means no new scars are created ^[1]. The surgical team carefully divides the spring in the middle to release any leftover tension and extracts the pieces ^[1][4].

Because the heavy lifting of reshaping the skull has already been done, the actual time your baby spends in the operating room is remarkably short—typically taking only 15 to 25 minutes ^[1][3].

Recovery at Home

Unlike the first surgery, which usually requires a hospital stay and significant monitoring, the spring removal is an outpatient procedure ^[1][2]. This means you can expect to take your baby home the exact same day, usually just a few hours after they wake up from anesthesia.

The recovery at home is much easier than the initial surgery. Blood loss during this second procedure is minimal ^[1]. Most babies bounce back very quickly, and pain management is generally handled with non-opioid medications like acetaminophen (or ibuprofen if your baby is at least 6 months old and cleared by your doctor) ^[5].

While you will receive specific instructions on when you can wash your baby’s hair, you will generally need to keep the incision sites clean and monitor them for a few days ^[2].

When to Call the Doctor

While complications are rare, you should contact your surgical team or seek emergency medical care if you notice signs of an issue, such as:

• A fever over 100.4°F (38°C) or vomiting ^[6]
• Increasing redness or unexpected swelling around the incisions ^[2]
• Pus or fluid leaking from the incision sites ^[2]

Understanding the Risks

While the idea of a second surgery is daunting, it is generally very safe. The major risks sometimes associated with craniosynostosis surgery—such as significant blood loss, dural tears (tears in the protective covering of the brain), or the need for blood transfusions—are primarily linked to the first surgery when the bone is cut ^[7][2].

For the removal procedure, the main consideration is the need for the second round of general anesthesia ^[1]. The most common (though still infrequent) risks are minor wound healing issues, such as a superficial infection at the incision site ^[2].

What Happens Next?

Once the springs are removed, the active expansion phase of treatment is over. However, your child’s journey isn’t entirely finished. Your baby will continue to have structured, long-term follow-up appointments with a multidisciplinary team to monitor their ongoing skull development, brain growth, and aesthetic outcomes as they get older ^[8][9]. While secondary cranial surgery is rare after spring-assisted cranioplasty, these check-ups ensure your child’s head shape remains stable and healthy as they grow ^[8][10].
