Cleft Lip & Palate Repair
Surgical correction of congenital cleft deformities
Cleft lip and palate repair encompasses a series of reconstructive surgical procedures designed to correct congenital facial deformities that occur when the tissues of the lip and roof of the mouth fail to fuse properly during fetal development. These conditions affect approximately one in every 700 births worldwide, making them among the most common congenital anomalies [2]. Without surgical intervention, cleft deformities can significantly impair feeding, speech development, hearing, and dental health.
The surgical approach to cleft repair is typically staged, beginning in infancy and potentially continuing through adolescence. Cleft lip repair (cheiloplasty) is usually performed between three and six months of age, while cleft palate repair (palatoplasty) is typically scheduled between nine and eighteen months [1]. Additional procedures, including alveolar bone grafting, rhinoplasty, and orthognathic surgery, may be required as the child grows to address ongoing functional and aesthetic concerns.
Modern cleft surgery has advanced significantly, with techniques that achieve excellent functional and aesthetic outcomes. A comprehensive cleft care team typically includes a plastic surgeon, oral and maxillofacial surgeon, otolaryngologist, speech-language pathologist, orthodontist, and pediatric dentist, all working collaboratively to ensure optimal long-term results for the patient.
Overview
Cleft lip and palate are among the most common congenital birth defects, resulting from incomplete fusion of facial structures during early embryonic development. A cleft lip involves a split or opening in the upper lip, which can range from a small notch to a complete separation extending into the nose. A cleft palate occurs when the roof of the mouth has an opening that connects to the nasal cavity. These conditions can occur independently or together, and may be unilateral (one-sided) or bilateral (affecting both sides).
The impact of untreated cleft deformities extends far beyond cosmetic concerns. Infants with cleft palate often have significant difficulty with feeding, as they cannot create adequate suction. As children develop, speech difficulties become apparent, with characteristic hypernasality and articulation errors. Chronic ear infections and hearing loss are common due to eustachian tube dysfunction [2]. Dental abnormalities, including missing or malformed teeth, frequently accompany the condition.
Surgical repair follows a carefully planned timeline aligned with the child's growth and developmental milestones. The initial cleft lip repair is typically performed around three to six months of age, once the infant has demonstrated adequate weight gain and overall health. This procedure reconstructs the lip anatomy, creating a functional and aesthetically natural-appearing lip. Cleft palate repair follows between nine and eighteen months, timed to precede the onset of meaningful speech development.
As the child grows, additional procedures may be necessary. Alveolar bone grafting, typically performed between ages seven and eleven when the permanent canine teeth are developing, fills the bony gap in the upper jaw with bone harvested from the hip or another donor site [1]. Secondary rhinoplasty may be performed in adolescence to refine the nasal appearance, which is frequently affected by the underlying cleft. Orthognathic surgery to correct jaw alignment may also be required once facial growth is complete.
The multidisciplinary team approach is essential to achieving optimal outcomes. Regular assessments from birth through adolescence ensure that each stage of treatment is appropriately timed and that developing issues are identified and addressed promptly. With comprehensive care, children born with cleft lip and palate can achieve excellent functional outcomes and lead normal, healthy lives.
Techniques & Approaches
The Millard rotation-advancement technique is the most widely used method for unilateral cleft lip repair [1]. This approach involves rotating the medial lip element downward while advancing a lateral lip flap into the resulting gap. The technique preserves the natural curvature of the Cupid's bow and philtral column, producing results that closely mimic normal lip anatomy. For bilateral cleft lip, the surgeon must address both sides, often using a modification of the Millard technique or a straight-line closure with careful attention to prolabial design.
Cleft palate repair employs several well-established techniques depending on the extent of the cleft. The two-flap palatoplasty (Bardach technique) involves raising mucoperiosteal flaps from both sides of the palate and bringing them to the midline for closure. The Furlow double-opposing Z-plasty is particularly effective for reorienting and lengthening the muscles of the soft palate, which is critical for achieving velopharyngeal competence and normal speech. The intravelar veloplasty reconstructs the levator veli palatini muscle sling, restoring the functional anatomy of the soft palate.
Alveolar bone grafting involves harvesting cancellous bone, most commonly from the iliac crest (hip bone), and packing it into the alveolar cleft. This provides a bony bridge that supports the eruption of permanent teeth, stabilizes the dental arch, and provides support for the nasal base. Some centers now use bone morphogenetic protein (BMP) or other bone substitutes to reduce donor-site morbidity, though autogenous bone remains the gold standard.
Secondary procedures may include columellar lengthening, alar cartilage repositioning, and septoplasty to improve nasal form and function. Velopharyngeal surgery, such as pharyngeal flap or sphincter pharyngoplasty, may be required if speech remains hypernasal after palate repair. Orthognathic surgery, typically Le Fort I osteotomy, corrects midface retrusion that commonly develops due to the effects of palatal scarring on maxillary growth.
Who Is a Good Candidate?
Ideal Candidates
The ideal candidates for cleft lip and palate repair are infants and children born with cleft deformities who are otherwise healthy enough to undergo general anesthesia. For initial cleft lip repair, infants should typically be at least ten weeks old, weigh at least ten pounds, and have a hemoglobin level of at least ten grams per deciliter, following the traditional "rule of tens" [1]. Patients should be free of active infections and any other medical conditions that would increase surgical risk.
Children being considered for palate repair should have adequate growth and nutritional status, be between nine and eighteen months of age, and have completed any necessary presurgical orthopedic treatment. Candidates for alveolar bone grafting are typically between seven and eleven years of age, with mixed dentition and the permanent canine tooth positioned to erupt into the grafted site. Adolescents and young adults are candidates for secondary procedures once facial growth is complete or nearly complete.
Not Suitable For
Surgery may need to be postponed for infants who are significantly underweight, have failure to thrive, or have active respiratory infections or other acute illnesses. Children with uncontrolled cardiac conditions, bleeding disorders, or other serious systemic diseases may require medical optimization before proceeding with surgery. Patients with Pierre Robin sequence or other syndromic conditions may require modified surgical timing and techniques.
Orthognathic surgery and definitive rhinoplasty should not be performed until facial growth is substantially complete, typically around age sixteen for females and eighteen for males. Performing these procedures prematurely can result in relapse and the need for additional surgery. Patients or families who are unable to commit to the extended, multiyear treatment plan and regular follow-up appointments may not achieve optimal outcomes, as cleft care requires consistent engagement with the multidisciplinary team across childhood and adolescence.
Risks & Benefits
Benefits
The primary benefit of cleft lip and palate repair is the restoration of normal facial anatomy, enabling proper feeding, speech development, and dental health. Early lip repair allows infants to feed more effectively and promotes bonding between the child and caregivers by creating a more typical facial appearance. Palate repair before the onset of meaningful speech gives children the anatomical foundation needed for normal language development.
Surgical correction dramatically improves quality of life for affected children and their families. Children who receive timely, comprehensive cleft care can participate fully in school and social activities without the functional limitations and social stigma that untreated clefts impose. The psychological benefits of surgical correction extend to the entire family, reducing parental anxiety and facilitating normal parent-child interactions.
Alveolar bone grafting supports proper dental development and eliminates the gap in the upper jaw, enabling orthodontic treatment to achieve a functional and aesthetically pleasing dental arch. Secondary procedures performed in adolescence, including rhinoplasty and orthognathic surgery, refine facial aesthetics and function at an age when self-image becomes increasingly important. The cumulative effect of comprehensive staged care is a young adult with near-normal facial appearance and full functional capability.
Risks & Considerations
As with any surgical procedure performed under general anesthesia, cleft repair carries risks of adverse anesthetic reactions, bleeding, infection, and poor wound healing. Fistula formation, where a small opening develops along the palate repair, occurs in approximately 5 to 15 percent of palate repairs and may require secondary surgery to close [3]. Wound dehiscence, or separation of the surgical repair, is uncommon but can occur, particularly if the repair is under excessive tension.
Velopharyngeal insufficiency, where the palate does not adequately close off the nasal cavity during speech, is the most significant functional complication of palate repair, affecting 15 to 25 percent of patients [1]. This condition produces hypernasal speech and may require secondary surgery such as pharyngeal flap or sphincter pharyngoplasty. Maxillary growth restriction is a long-term concern, as palatal surgery can create scar tissue that impedes normal midface development, potentially necessitating orthognathic surgery in adolescence.
Scarring at the lip repair site varies in severity and may require scar revision. Nasal asymmetry is common and often requires secondary rhinoplasty. Dental complications, including missing teeth, enamel defects, and malocclusion, are inherent to the cleft condition and require ongoing orthodontic management. Psychological impacts, including issues with self-esteem and social integration, should be monitored and addressed with appropriate support throughout childhood and adolescence.
Alternative Procedures
For cleft lip and palate, surgery is the definitive and necessary treatment; there are no non-surgical alternatives that can achieve functional correction. However, presurgical interventions can optimize outcomes before the primary surgical repair. Nasoalveolar molding (NAM) is an orthopedic technique used in the first months of life to gradually reshape the gum, lip, and nostril before surgery [3]. By approximating the cleft segments and improving nasal cartilage symmetry, NAM can reduce the complexity of the initial surgery and improve aesthetic outcomes.
Lip taping and other passive appliances represent simpler presurgical approaches that can help narrow a wide cleft lip before surgical repair. These are less labor-intensive than NAM but may be less effective in cases of wide or bilateral clefts. Palatal obturators, custom prosthetic devices that cover the palatal opening, can be used to assist with feeding in infancy before palate repair, though they do not replace the need for surgical closure.
Speech therapy is an essential adjunct to surgical treatment, not an alternative. While surgery creates the anatomical foundation for normal speech, skilled speech-language pathology is almost always necessary to help children develop proper articulation patterns. In some cases, intensive speech therapy can reduce or eliminate the need for secondary velopharyngeal surgery. Orthodontic treatment works alongside surgical care to guide dental development and jaw alignment throughout childhood and adolescence.
Preparation & Recovery
Pre-Surgery Preparation
Preparation for cleft lip repair begins with a thorough evaluation by the cleft team, including assessment of the infant's overall health, nutritional status, and airway. If nasoalveolar molding is planned, the process begins within the first few weeks of life and continues until the time of lip repair. Parents receive extensive education about the surgical procedure, expected outcomes, and postoperative care requirements. Specialized feeding bottles and techniques may be introduced to optimize nutrition before surgery.
Before each surgical procedure, standard preoperative testing is performed, including blood work and any additional studies indicated by the child's medical history. Patients must follow nothing-by-mouth guidelines appropriate for their age, typically clear liquids up to two hours before anesthesia and breast milk or formula up to four hours before. Parents should inform the surgical team of any recent illnesses, medication use, or changes in the child's health. Photography is taken preoperatively to document the deformity and plan the surgical repair.
For older children undergoing secondary procedures such as bone grafting or rhinoplasty, preparation includes orthodontic treatment to align the dental segments, dental imaging to assess the position of developing teeth, and age-appropriate discussion of the surgical plan and recovery expectations.
Post-Surgery Care
Following cleft lip repair, the infant is typically monitored in the hospital for one to two days. Arm restraints (no-nos) are applied to prevent the baby from touching the surgical site. Feeding is resumed with a special bottle or syringe, and breast-feeding may be carefully reintroduced after the initial healing period. The surgical site is kept clean and moist with antibiotic ointment, and parents are instructed to avoid allowing anything hard to contact the lip repair.
After palate repair, the child is monitored for airway swelling and adequate oral intake before discharge, typically after one to two nights. A liquid diet progresses to soft foods over two to three weeks, and hard foods and utensils are restricted for approximately six weeks to protect the repair. Pain is managed with age-appropriate analgesics, and antibiotics may be prescribed. Follow-up appointments are scheduled at one week, one month, and three months post-surgery.
Long-term aftercare involves regular visits with the cleft team, typically every six to twelve months during childhood. Speech therapy assessments begin around eighteen months to two years of age, with active intervention as needed. Audiological monitoring continues throughout childhood due to the increased risk of middle ear disease. Orthodontic care begins in the mixed dentition phase and continues through adolescence. Psychological screening and support are provided at key developmental stages.

Expected Results
Modern cleft lip repair achieves excellent aesthetic outcomes in the vast majority of cases. Parents can expect a well-defined Cupid's bow, symmetric lip height, and a natural-appearing scar that continues to improve over the first one to two years. Minor lip asymmetries or scar irregularities may be present and can often be refined with secondary procedures during childhood or adolescence. The nose, which is invariably affected by the underlying cleft, will be improved but may not achieve perfect symmetry, and secondary rhinoplasty is commonly planned for the teenage years.
Functional outcomes following cleft palate repair are generally very favorable. Approximately 75 to 85 percent of children achieve adequate velopharyngeal function for normal speech after initial palatoplasty [1]. The remaining 15 to 25 percent may require secondary speech surgery to correct persistent hypernasality. With comprehensive speech therapy, the large majority of cleft-affected children develop intelligible, socially acceptable speech. Hearing outcomes improve significantly after palate repair, though ongoing monitoring and management of middle ear disease remain important throughout childhood.
Long-term outcomes depend significantly on the severity of the original cleft, the quality of initial surgical repair, adherence to the recommended treatment timeline, and consistent follow-up with the multidisciplinary team. Children who receive comprehensive, well-coordinated care from an experienced cleft team achieve outcomes that allow them to function normally in school, social settings, and eventually the workplace. Psychological support for the child and family is an important component of care, as the visible nature of the condition and the extended treatment timeline can present emotional challenges.

Factors affecting cost:
The cost of cleft lip and palate repair is influenced by the number and complexity of staged procedures required over the course of treatment. Initial lip and palate repairs represent distinct surgical events, each with associated hospital, anesthesia, and surgeon fees. The geographic location of the treatment center, the experience of the surgical team, and whether the procedure is performed at an academic medical center or community hospital all affect pricing. Additional costs include presurgical orthopedics such as nasoalveolar molding, orthodontic treatment spanning many years, speech therapy, audiological services, and secondary surgical procedures. The total cost of comprehensive cleft care from birth through adolescence can be substantial, but insurance coverage significantly offsets out-of-pocket expenses for most families.
