What Is Cleft Lip and Palate? Causes and Treatment
Cleft lip and palate is a congenital condition caused by the incomplete fusion of lip and palate tissues during facial development. With a multidisciplinary treatment process that begins early, function and appearance can be greatly improved; corrective surgery can also be performed in adulthood.
What Is Cleft Lip and Palate?
Cleft lip and palate originates from a disruption in the fusion of facial tissues between the 4th and 12th weeks of embryonic development. During this process, the lip, the palate, or both may be affected. The resulting structural difference has both functional and aesthetic dimensions; feeding, speech, and hearing may all be impacted.

What is the difference between a cleft lip and a cleft palate?
A cleft lip affects only the upper lip and presents as a visible split or notch. A cleft palate involves the roof of the mouth — the hard and soft palate — and is not always visible from the outside. These two conditions can occur independently or together in the same patient. In clinical practice, the most commonly encountered presentation is the combined form, in which both a cleft lip and a cleft palate are present.
How common is this condition?
Worldwide, cleft lip and palate occurs in approximately one in every 700 live births, making it one of the most common congenital anomalies. A similar frequency is observed in Turkey, although regional and ethnic differences are known to influence statistics.
Which types are more prevalent?
| Type | Description |
|---|---|
| Unilateral cleft lip | Affects only one side of the lip; the most common form |
| Bilateral cleft lip | Affects both sides of the lip; requires a more complex surgical process |
| Incomplete (partial) cleft | The tissue separation is not complete; a partial opening is present in the lip or palate |
| Complete cleft | The tissue separation encompasses all layers and may extend to the base of the nose |
| Combined cleft lip and palate | Both structures are affected together; a multidisciplinary approach is essential |
Why Does Cleft Lip and Palate Occur?
The question families ask most often after a diagnosis is "why did this happen?" The answer usually cannot be attributed to a single cause; genetic predisposition and environmental factors both play a role.
How significant are genetic factors?
A family history of cleft lip and palate increases the risk; however, this does not necessarily mean the condition is hereditary. A significant proportion of cases have no known family history. Genetic predisposition may create a background susceptibility, but it is not sufficient on its own. There is therefore no medical basis for parents to hold themselves responsible.
What environmental factors during pregnancy play a role?
Folic acid deficiency, certain antiepileptic medications, and tobacco use during the first trimester of pregnancy have been associated with the development of cleft lip and palate. Alcohol consumption and certain infections are also cited among risk factors. The presence of these factors does not definitively indicate that a cleft will occur; they are only known to increase the likelihood.
Information: Adequate folic acid intake before and during the first trimester of pregnancy is among the recommendations aimed at reducing the risk of both neural tube defects and cleft lip and palate. It is advisable to consult your obstetrician on this matter.
Can it be detected prenatally?
A cleft lip can be seen on a detailed ultrasound examination at approximately 18 to 20 weeks of gestation. However, a cleft palate cannot always be clearly identified on ultrasound; the baby's position and image quality directly affect the outcome. While prenatal diagnosis is valuable in terms of giving the family time to prepare, a definitive diagnosis is made after birth.
How Does the Treatment Process Progress?
The treatment of cleft lip and palate is not a matter of a single operation. It is a process spanning from infancy to adulthood that encompasses multiple areas of specialization. Each phase of this process is built upon the one before it.
What steps are taken during infancy?
Immediately after birth, the priority is feeding support. In the presence of a cleft palate, difficulty with suckling may arise; specialized bottles and feeding techniques come into play during this period. In some centers, an orthodontic preparatory procedure called NAM (nasoalveolar molding) is applied prior to surgery. With this method, the nasal and gum tissues are shaped before the operation.
How many stages does the surgical intervention involve?
Lip repair is generally planned between 3 and 6 months of age. Palate repair is targeted between 9 and 18 months. These timeframes are shaped by the baby's general health condition and the surgeon's assessment; definitive dates are determined according to individual circumstances.
Is corrective surgery possible in adulthood?
After growth is complete, secondary corrections can be made, particularly in the nasal and lip regions. In adult patients, nasal shape, lip symmetry, and scar appearance can be addressed at this stage. Detailed information about this procedure, known as cleft lip nose surgery, is available on our cleft lip nose surgery page.
Which specialties beyond surgery are involved in the process?
- Orthodontics: Monitoring dental and jaw development; plate and bracket treatments
- Speech therapy: Supporting the development of voice and articulation
- Ear, nose, and throat: Management of middle ear fluid and hearing problems
- Child psychiatry and psychology: Supporting the emotional process of the child and the family
- Pediatrics: Monitoring overall growth and development
How is speech development supported?
Because a cleft palate affects the function of the soft palate, it can cause air to escape through the nose during speech. This is described as hypernasality (nasal speech). It has been observed that this presentation can be largely corrected through speech therapy begun after palate repair. Therapy started early supports the child in reaching a level of speech comparable to that of peers before the school years.
How Does the Process Work for International Patients?
How is planning carried out for patients coming from abroad?
For patients or parents living abroad, the process begins with sharing imaging results and medical documents digitally. Current photographs, ultrasound reports, and any previous surgical records provide a sufficient starting point for remote evaluation. An initial consultation can be conducted via video call; the treatment plan is then established following this meeting.
What logistical information is needed for treatment in Istanbul?
The clinic is located in the Ataşehir district of Istanbul. This location, at a reasonable distance from both Sabiha Gökçen and Istanbul airports, offers a practical option for international travel. The post-operative follow-up process can be managed through remote communication and periodic check-up visits; details are planned according to the patient's condition.
Information: International patients are advised to contact the clinic directly to schedule a preliminary evaluation appointment and to initiate the document-sharing process.
Frequently Asked Questions
Is cleft lip and palate hereditary?
While genetic predisposition is a risk factor, not every case is hereditary. Cleft lip and palate can also occur in many children with no family history. Genetic counseling can be a valuable resource for couples with a family history of the condition.
Will there be scarring after surgery?
The formation of a fine scar following surgical repair is an expected part of the process. This scar fades over time and becomes less noticeable. Options such as silicone gel, laser treatment, or additional minor corrections may be considered for scar management. The outcome varies depending on the patient's skin type and healing process.
Can a child with cleft lip and palate speak normally?
It has been observed that the vast majority of children show normal speech development with palate repair performed at an early stage followed by speech therapy. Starting treatment early is a decisive factor in supporting the development of speech skills.
Is it too late for an adult patient to seek treatment?
Corrective surgery can be performed in adulthood as well. Once growth is complete, nasal shape, lip symmetry, and scar appearance can all be addressed. Age alone does not constitute a barrier; the patient's overall health and expectations are the determining factors in the evaluation process.
