Will My Child Need Jaw Surgery or a Cleft Nose Job?

Not every child with a cleft lip and palate will need jaw surgery or a definitive cleft rhinoplasty (nose surgery) when they grow up. The need for these procedures varies widely based on individual facial growth, bite alignment, breathing, and personal goals. When recommended, these surgeries are typically planned in the late teens when facial growth is nearly complete. While they often represent major later steps in a cleft treatment plan, the journey is highly individualized, and ongoing dental or functional care may still be needed.

Why Wait Until the Late Teens?

The timing of these surgeries depends on skeletal maturity—an estimate of when the facial bones have nearly finished growing. For many, this milestone is reached between ages 16 and 20 ^[1][2], but the exact timing varies by child, sex, and the specific cleft anatomy ^[3].

Surgeons generally wait until growth is nearly complete because operating too early carries a risk: residual facial growth, particularly of the lower jaw, could create a new mismatch in the bite after the surgery ^[4]. While waiting improves the long-term stability of the results, it does not guarantee absolute permanence, and a small amount of relapse (shifting back) can still occur over time ^[5].

To estimate skeletal maturity, your cleft team will track your child’s growth over time using regular exams, serial dental records, and sometimes specific x-rays of the hand or neck ^[6].

Orthognathic (Jaw) Surgery

Note: Late-teen jaw surgery is different from an alveolar bone graft, which is typically done much earlier (around ages 8–11) to repair the gum line.

In some children with a cleft, the upper jaw (maxilla) does not grow forward enough to match the lower jaw. This condition, called maxillary hypoplasia, is caused by a complex combination of the cleft anatomy, intrinsic growth patterns, and the effects of earlier surgeries ^[7]. This can result in an underbite or crossbite.

If orthodontics alone cannot correct the bite, your team may recommend a Le Fort I maxillary advancement. (Depending on the specific bite, some patients might need different orthodontic approaches or surgery on both jaws).

• What it is: The surgeon carefully frees the upper jaw, moves it forward into alignment, and secures it with small plates and screws ^[8].
• The goals: This surgery aims to improve chewing function, align the bite, and balance the facial profile ^[8]. Some patients also experience improved airway and nasal breathing, though this is not guaranteed for everyone and depends on individual anatomy ^[9].
• Speech considerations: Moving the upper jaw forward alters the space at the back of the throat. For some patients, this can cause or worsen velopharyngeal insufficiency (VPI)—where the soft palate cannot close fully against the back of the throat, allowing too much air to escape through the nose during speech (hypernasality) ^[10][11]. Your team will require a thorough speech evaluation before surgery and will monitor speech closely afterward. Additional speech therapies or procedures are occasionally needed ^[12].
• What to expect: This is a major surgery requiring a hospital stay, a temporary soft or liquid diet, and management of swelling and possible numbness. It also requires extensive orthodontic treatment (braces) both before and after the surgery to coordinate the bite.

Definitive Cleft Rhinoplasty

Many children have adjustments made to their nose during their initial lip repair as an infant, or an “intermediate” surgery during childhood to address severe asymmetry or breathing issues ^[13][14]. However, a definitive cleft rhinoplasty—a comprehensive surgery to reshape the nose for long-term function and appearance—is usually considered near skeletal maturity ^[2][15].

• What it is: An operation that may address the septum (the internal divider of the nose), nasal airway, nostril shape, and nasal tip ^[16].
• The goals: To improve breathing and facial symmetry. Perfect symmetry or completely clear breathing is not guaranteed, and revision procedures are sometimes needed later depending on how the tissues heal.
• How it relates to jaw surgery: Because the upper jaw forms the base of the nose, moving the jaw inherently changes the nose’s foundation and appearance. If a young adult needs both surgeries, the jaw surgery is usually performed first ^[17]. The definitive rhinoplasty is often staged afterward once the jaw is stable, though some specialized surgical teams may combine the procedures depending on the patient’s specific anatomy and goals.

Preparing for the Future

You do not need to make decisions about these surgeries while your child is young. The best approach is to maintain regular visits with your craniofacial team and orthodontist. As your child reaches adolescence, they should take an active role in these conversations, helping to weigh the functional benefits, recovery burden, and aesthetic priorities.
