A cleft palate is a midline opening in the roof of the mouth that ranges from a narrow groove behind the teeth to a wide gap that exposes the nasal cavity. The split forms when the palatal shelves fail to fuse between the sixth and ninth weeks of embryonic development.
Some clefts are visible at a glance, while submucous clefts hide beneath an apparently normal surface and reveal themselves only through clues like a split uvula, nasal regurgitation during feeds, or chronic ear fluid.
This guide gives parents a clear visual handle on what a cleft palate actually looks like, from obvious gaps to subtle submucous clues, while walking through the forms, severity levels, and confirmation steps clinicians use.
A Quick Look at Cleft Lip and Cleft Palate
Two related but distinct birth differences,cleft lip and cleft palate,fall under the broader umbrella known as orofacial cleft. A cleft palate is an opening along the midline of the roof of the mouth that forms when the palatal shelves fail to fuse during early development. The split can involve the hard palate at the front, the soft palate at the back, or both.
How a Cleft Lip Differs From a Cleft Palate
An opening in the upper lip, sometimes extending into the gumline (the alveolar ridge), characterizes a cleft lip. It results from incomplete fusion of the tissue that forms the lip between the fourth and seventh weeks of pregnancy. The opening may be a small notch or a wide gap that runs from the lip into the nostril.
They Can Appear Together or Independently
Cleft lip and cleft palate frequently occur together, forming what clinicians call a cleft lip and palate. Either can also appear on its own. A baby may have a cleft lip with an intact palate, or a cleft palate with no visible lip involvement at all. The CDC tracks cleft lip with cleft palate and cleft palate alone as separate categories for exactly this reason.
How the Cleft Appears in the Mouth of a Newborn
Inside a newborn’s mouth, examiners frequently spot a cleft palate as a longitudinal split stretching from behind the front teeth back toward the soft palate. In the most common presentation, you can see straight down through the gap into the pink mucosal lining of the nasal cavity above. That single finding signals the diagnosis to anyone examining the baby.
From the Alveolar Ridge to the Soft Palate
The opening typically begins at the alveolar ridge, the bony arch where the teeth will eventually erupt, and extends backward along the midline. In some babies the cleft stops partway through the hard palate. In others it continues all the way through the soft palate and even splits the uvula, the small fleshy structure that hangs at the back of the throat.
Narrow Groove or Wide Gap
Some clefts measure just a few millimeters across, appearing as little more than a narrow groove. Others look like a yawning chasm, wide enough that the tongue can pass upward into the nasal passage during feeding. Wider clefts cause more obvious feeding and breathing issues right away, while narrower ones may go unnoticed until a feeding specialist or pediatrician looks closely.
Most cleft palates are identified during the very first physical examination after birth. The clinician tilts the baby’s head back, shines a light into the mouth, and runs a finger along the palate to feel for any break in the tissue. The exam is brief, but remarkably reliable for catching visible clefts.
Tip: A newborn’s mouth is easiest to examine during a strong cry, when the palate lifts and any gap stretches open clearly.
Forms and Severity You Might See
Not all cleft palates look alike. They vary by location, by how far they extend, and by whether they affect one side or both. The table below summarizes the most common forms, though individual presentations can blend categories.
| Type | What It Looks Like | Typical Extent |
|---|---|---|
| Unilateral cleft lip | Single opening on one side of the upper lip, often extending into the nostril | One side of the lip and possibly the gum |
| Bilateral cleft lip | Openings on both sides of the lip, with a central segment of tissue projecting forward | Both sides of the lip and the gum |
| Incomplete cleft palate | Partial split that stops partway through the hard or soft palate | Any portion of the palate, uvula usually intact |
| Complete cleft palate | Full-length split from alveolar ridge to uvula | Entire palate, often with nasal cavity exposed |
| Submucous cleft palate | Surface looks intact but underlying muscle is separated | Midline of soft palate, often hidden |
One Side or Both
A unilateral cleft affects only the left or right side of the lip and gum. A bilateral cleft affects both sides, leaving a central piece of tissue, sometimes called the premaxilla, that projects forward from the gum. Bilateral clefts tend to look more dramatic and usually involve a wider separation across the upper jaw.
Partial or Complete
An incomplete cleft stops somewhere along the palate without reaching its full length. A complete cleft extends all the way from the gumline back through the uvula, exposing the nasal floor. Complete clefts are easier to spot at birth because the nasal cavity is clearly visible through the opening.
Submucous Cleft Palate
The submucous variant slips past detection more often than any other form. The surface mucosa looks smooth and intact, but the underlying muscle has failed to fuse. The palate appears normal from the outside, yet the baby may still struggle to feed, produce nasal-sounding speech later on, or develop chronic ear fluid. Submucous clefts account for roughly 1 in 4 cleft palate diagnoses and usually surface only when a feeding or speech concern prompts a closer look.
Yet the more overt forms often mask subtler variants hiding just beneath the surface.
Subtle Signs That Are Easy to Miss
When the palate surface looks normal, a few subtle clues can point toward a hidden cleft. These signs matter because an unrecognized submucous cleft can delay feeding milestones, speech development, and middle-ear health.
- Bifid uvula: A uvula that appears split into two small tips rather than one rounded structure can indicate underlying muscle separation.
- Bluish midline stripe: A pale or bluish discoloration running along the midline of the soft palate often reflects thin mucosa covering separated muscle beneath.
- Notched back edge: A V-shaped notch where the hard palate meets the soft palate can signal a submucous cleft.
- Feeding difficulties: Milk leaking from the nose during feeds, long feeding times, or poor weight gain can all point to a palate that isn’t sealing properly.
- Nasal regurgitation: Food or liquid that comes back through the nostrils during feeding suggests the soft palate can’t separate the mouth from the nose.
- Chronic ear fluid: The same muscles that close off the nasal passage also open the Eustachian tube. When those muscles don’t work right, fluid builds behind the eardrum.
Note: A bifid uvula alone doesn’t confirm a submucous cleft, but it raises the index of suspicion enough to warrant a careful exam.
How Doctors Visually Confirm the Diagnosis
Diagnosis starts with the eyes and the fingertips. During the newborn exam, the pediatrician tilts the baby’s head back, opens the mouth gently, and inspects the full length of the palate under good light. A gloved finger then sweeps along the midline to feel for any break or notch in the tissue.
The Visual Inspection
The clinician looks for a visible split in the hard or soft palate, an asymmetric or split uvula, and any exposed nasal lining. A cleft lip is almost always visible from across the room, but a cleft palate requires looking directly inside the mouth.
The Feel Test
Running a finger along the palate catches what the eyes sometimes miss. A notched back edge of the hard palate, called a bony notch, is one of the classic findings in a submucous cleft. The clinician may also press gently on the soft palate to feel whether the underlying muscle is continuous or gapped.
Referral to a Craniofacial Team
Suspected cases usually trigger a referral to a specialized craniofacial team shortly after birth. These specialists, often coordinated through the American Cleft Palate-Craniofacial Association, include plastic surgeons, pediatric dentists, audiologists, speech-language pathologists, and feeding therapists. Imaging, hearing tests, and feeding assessments help the team plan palate repair surgery and follow-up care.
Confirmation then shifts the focus toward assembling the right team and timing each step.
What to Keep in Mind Once a Cleft Is Identified
Seeing a cleft palate for the first time can feel overwhelming. A few grounding facts help most parents move from shock into action.
Appearance Does Not Predict Outcome
The visual severity of a cleft has very little to do with how well a child will do long-term. Wide clefts and narrow clefts alike respond to modern surgical repair, and most children go on to speak clearly, eat normally, and thrive. The quality of the team providing care matters far more than the size of the gap.
Standard Care Covers the Whole Picture
Repair surgery, typically performed between 9 and 18 months of age, closes the palatal split. Before surgery, feeding support with specialized bottles or nipples keeps the baby growing. After surgery, speech follow-up and hearing monitoring catch any velopharyngeal insufficiency, a condition in which the soft palate can’t fully close off the nose during speech.
Specialized Teams Make a Real Difference
Connecting early with a craniofacial team helps parents understand exactly what they’re looking at and what comes next. These teams walk families through feeding techniques, surgical timing, orthodontic planning, and speech therapy. Coordinated, multidisciplinary care is the backbone of good outcomes, a point emphasized by groups such as Smile Train and aligned with WHO guidance on comprehensive cleft care.
Bottom Line
A cleft palate is a midline opening in the roof of the mouth that ranges from a narrow groove to a wide gap exposing the nasal cavity. Submucous clefts can hide beneath a normal-looking surface and reveal themselves only through subtle clues like a split uvula, feeding trouble, or chronic ear fluid. Diagnosis relies on a careful visual and tactile exam, and outcomes are strong when a craniofacial team guides feeding, surgery, and speech support from the start.
FAQ
Can a cleft palate be seen on an ultrasound?
Some cleft lips and a portion of cleft palates can be visualized during a mid-pregnancy anatomy scan, typically around 18 to 22 weeks. Clefts that involve only the soft palate are harder to detect prenatally and may not show up until after birth.
What does a cleft palate look like in a baby?
In a newborn, a cleft palate appears as a midline split running from behind the front teeth back toward the throat. Some babies show only a narrow groove, while others have a wide gap that exposes the nasal cavity above.
What are the different types of cleft palate?
Cleft palates are generally grouped into incomplete clefts that stop partway through the palate, complete clefts that span its full length, and submucous clefts where the surface looks intact but the underlying muscle is separated. They may occur with or without a cleft lip.
How is a cleft palate diagnosed at birth?
A pediatrician inspects the newborn’s mouth and runs a gloved finger along the palate during the first physical exam. Any visible gap, notch, or split uvula prompts referral to a craniofacial team for further evaluation.
Does a cleft palate change the way the face looks?
When a cleft palate occurs without a cleft lip, the outward appearance of the face is usually normal. Clefts that involve the lip or gum do change the look of the upper lip and nose, and modern surgical repair addresses both form and function.
What does a submucous cleft palate look like?
At first glance, a submucous cleft palate can resemble a normal roof of the mouth,until a careful exam reveals a bluish midline stripe, a bifid or split uvula, or a notched back edge of the hard palate. Feeding difficulties and nasal-sounding speech later in infancy are common tip-offs.
