When Your Baby Arrives with a Cleft Lip and Palate

When Your Baby Arrives with a Cleft Lip and Palate


When a baby’s lip and palate do not properly form before birth, this condition is known as cleft lip and palate. It is possible for a baby could be born with one, or both of these variations.

Cleft lip occurs when the tissue that normally comprises the lip doesn’t completely form before birth. There will be a curve in the lip where it does not fully meet. Cleft lip ranges from a very small defect to one that goes up toward the nose. This condition develops somewhere in the fourth to seventh weeks of pregnancy when the lips develop.

Cleft palate develops some time between the sixth and ninth weeks of pregnancy. It occurs when the roof of the mouth (known as the palate) does not join completely. According to the Centers for Disease Control and Prevention, an estimated 2,650 babies are born with a cleft palate in the United States and another 4.440 are born with a cleft lip.

What Causes Cleft Lip and Palate?  

In most instances, a doctor doesn’t know what causes a child to be born with a cleft lip/palate while another is not. However, there are some risk factors that are known to increase a child’s risk for being born with a cleft lip/palate. These include:

  • Smoking: Women who smoke during pregnancy are more likely to give birth to a baby with cleft lip/palate.
  • Diabetes: Women with gestational diabetes or pre-existing diabetes prior to getting pregnant are more likely to have a child with cleft lip than those who do not.
  • Medications Taken: Taking the epilepsy medications topiramate or valproic acid during the first trimester of pregnancy are at greater risk for cleft clip than those who do not.

Sometimes a doctor can diagnose these conditions during pregnancy via an ultrasound. However, some forms of cleft palate may be especially hard to diagnose.

What Are the Treatments for Cleft Lip/Palate?

The presence of a cleft lip and/or palate can create feeding difficulties for a baby as well as present trouble speaking, dental problems, and eating later in life. As a result, doctors will often recommend surgery to repair a cleft lip and/or palate. Because both the lip and palate are integral to eating, doctors usually perform these surgeries early in life, sometimes within the first 12 to 18 months of life, depending on the severity of the condition and other abnormalities a child may have experienced. In the meantime, there are special bottles that can help a baby feed until the cleft lip and/or palate are repaired.

Sometimes surgical repair requires several surgeries for a baby to have the gap in the lip and hole in the roof of the mouth to repair. A child with cleft lip and palate will also often see a hearing specialist known as an audiologist because children with cleft lip/palate may also experience hearing problems due to excess fluid buildup in the ears that may require ear tubes to promote drainage.

As a child grows, it’s possible they may need a bone graft to repair the gum and jaw area. This will help a child’s permanent teeth to be more firmly implanted. While not all children with cleft palate require this procedure, it is a possibility.

Twin-to-Twin Transfusion Syndrome

What is Twin-to-Twin Transfusion Syndrome?

Twin-to-twin transfusion syndrome or TTTS, a rare condition affecting identical twins, causes the two fetuses to get unequal blood supply. It can occur at any stage of pregnancy [1], leading to various congenital defects and even death of one or both twins.

Other Names: Twin Oligohydramnios-Polyhydramnios Sequence (TOPS) and Feto-Fetal Transfusion Syndrome (FFTS).

Does Twin-to-Twin Transfusion Syndrome Occur in Fraternal Twins?

It only affects monochorionic twins (twins sharing a single placenta), meaning they have to be monozygotic (derived from the same egg) and identical to be affected by TTTS. Identical twins having separate placentas (dichorionic twins) do not have this condition, even if their placentas implant so close to each other that they may seem to have fused together [2].

Twin-to-Twin Transfusion Syndrome Mechanism

Identical twins or higher multiples sharing the same placenta have blood vessels within the placenta connecting their blood supplies. In TTTS, one twin (the donor) pumps too much blood to the other twin (the recipient), causing the second twin to have excessive blood while the first one has too little. As a result, the recipient twin produces higher than normal amounts of urine [3], which may lead to an enlarged bladder, excessive amniotic fluid (polyhydramnios), hydrops, cardiac strain, heart enlargement and prenatal heart failure. On the other hand, the donor twin produces extremely low amounts of urine which may result in dehydration [4], low amniotic fluid levels (oligohydramnios) and constriction or absence of bladder.

What are the Stages of Twin-to-Twin Transfusion Syndrome?

Fetal surgeon Dr. Ruben Quintero proposed the following staging system, based on the ultrasound and clinical criteria [5], for classifying the severity of TTTS:


Oligohydramnios (donor)/ Polyhydramnios (reciever)

Absence of bladder in donor (on ultrasound)

Doppler ultrasound showing blood flow abnormalities in both twins

Ascites (fluid accumulation in peritoneal cavity), scalp edema [21], pericardial or pleural effusion, excessive hydrops

Death of one or both fetuses





















Other staging systems have also been proposed as the Quintero one does not provide any information about the prognosis. Depending on the time of occurrence and nature of progression, twin-twin transfusion syndrome is sometimes classified as:

  • Acute TTTS [1]: Progresses quickly, generally after the 30th week of pregnancy, without significant warning signs. It may even occur during labor (in vaginal birth) or after clamping the umbilical cord of one baby.
  • Chronic TTTS: The common form of transfusion, occurring gradually over time with distinct signs and symptoms visible on ultrasound findings. These cases are generally diagnosed between the 15th and 20th week of pregnancy.

What Causes Twin-to-Twin Transfusion Syndrome?

Researchers are still trying to find the exact causes responsible for this condition as no genetic or environmental factors are known to play any role in its occurrence [2]. The complication does not occur from anything the mother did or did not do before or after conception. It is believed to result from a random placental abnormality as no hereditary or maternal condition has been found to be responsible either.

What are the Symptoms of Twin-to-Twin Transfusion Syndrome?

Maternal Symptoms

  • Braxton Hicks contractions
  • Rapid weight gain
  • Abdominal and back pain
  • Enlarged belly for a certain gestational age [6]
  • Abdominal tightness
  • Feeling of excessive abdominal pressure
  • Breathlessness
  • High blood pressure [8]
  • Vomiting

Donor Twin

  • Smaller size compared to the other twin [7]
  • Paleness
  • Anemia

Recipient Twin

  • Large size compared to the other twin [9]
  • Redness due to excessive blood
  • Increased blood pressure

Inequality between the sizes of identical twins is known as discordant twins [7].

How to Prevent Twin-to-Twin Transfusion Syndrome?

It is not possible to prevent TTTS due to its unknown etiology. Experts recommend following certain measures that may reduce the risk of the complication:

  • Maintaining a proper healthy diet prior to and during pregnancy [10]
  • Taking prenatal supplements recommended by one’s doctor
  • Attending prenatal appointments regularly for monitoring the procession of pregnancy

How is Twin-to-Twin Transfusion Syndrome Diagnosed?

The most essential step for evaluating a twin or triplet (or higher) pregnancy for TTTS is to find out if the twins are sharing a single placenta [3]. Determining the fetal sizes and amniotic fluid levels around each baby also helps with the diagnosis.

Fetal Ultrasound – Ultrasound imaging is the best diagnostic method for detecting the syndrome, especially between the 14th and 22nd week of pregnancy [11]. Its purposes include:

  • Evaluating the amniotic fluid levels around each twin
  • Eliminating any structural deformities in the twins
  • Confirming the location of the placenta
  • Assessing the insertion of the umbilical cord into the placenta
  • Assessing the membrane separating the twins

Fetal Echocardiogram (ECHO) – It is used for:

  • Assessing the development and functioning of the hearts of both the twins
  • Detecting any cardiac abnormalities in the recipient twin

Amniocentesis – Involves collecting an amniotic fluid sample from the mother for:

  • Assessing the development of various internal organs
  • Ruling out chromosomal abnormalities in the twins (genetic amniocentesis)

It is not used unless the above tests fail to confirm the diagnosis.

Other diagnostic tests performed for assessing the condition in the infants after birth [9]:

  • Complete blood count
  • Comprehensive metabolic panel for determining electrolyte balance
  • Blood clotting studies such as partial thromboplastin time (PTT) and prothrombin time (PT)
  • Chest x-ray

Twin-to-Twin Transfusion Syndrome Differential Diagnosis

  • Uteroplacental insufficiency
  • Abnormalities in cord insertion causing growth disturbances
  • Preterm premature rupture of membranes (PROM) of one twin
  • Discordant structural or chromosomal abnormalities of one twin
  • Intrauterine infection [12]
  • Hydrops Fetalis
  • Polycythemia (increased RBC count)
  • Oligohydramnios or Polyhydramnios [13]
  • Anemia of the newborn

Twin-to-Twin Transfusion Syndrome Treatment and Management

The treatment depends on the severity of the condition and the time of diagnosis.

Management of Mild TTTS

Mild cases do not usually require surgical intervention. Management of such cases involves close monitoring of the fetal development using fetal ultrasound and echocardiography [3]. Regular monitoring allows doctors to address any sign of aggravation of the disorder as soon as possible. Complete bed rest along with proper nutritional therapy is often prescribed to the mother for managing the condition and preventing it from worsening.

Amnioreduction (Removal of Excess Amniotic Fluid)

Draining the excess amniotic fluid from the amniotic sac of the recipient twin may help to improve the blood flow. It may also provide temporary relief to the mother [14].

Fetoscopic Laser Treatment

One of the most common treatment options for severe TTTS, the invasive surgery involves making a small incision in the mother’s belly for monitoring and permanently disconnecting some of the blood vessels connecting the twins. This helps to halt the progression of the disorder by stopping the blood transfusion from the donor twin to the recipient twin [3].


It involves making a small hole in the intervening amniotic membranes of the twins (with an amnioreduction needle) to equalize the fluid levels in the two amniotic sacs [14].

Selective Feticide

In extremely severe cases, doctors may recommend an invasive surgery to stop the blood supply to the dying twin so that the other twin may be better provided for [14]. Selective feticide is not considered unless doctors find it to be the only way for avoiding losing both twins. It helps to reduce the risk of neurologic impairment and death in the remaining twin.

Delivery of the Twins

The doctor may recommend inducing labor or a c-section delivery as soon as the organs of the babies are developed enough to function on their own [20]. This may help to reduce the chances of various complications.

Twin-to-Twin Transfusion Syndrome Prognosis

Untreated cases of severe TTTS often have a poor outcome as it is associated with 90% mortality rate. The surviving twins run a 15% to 50 % risk of various long-term neurologic complications (e.g. cerebral palsy, mental retardation, hearing loss and vision loss) [15]. However, modern treatment procedures have improved the survival rate significantly, lowering the risks of neurological handicaps. The outcome of laser surgery varies greatly with the survival rate for one/both twins being around 91%.

Twin-to-Twin Transfusion Syndrome Complications

Maternal Complications

  • Premature labor due to induction or ruptured membranes
  • Premature rupture of the membranes [16]
  • Placental abruption
  • Maternal mirror syndrome (mother having the same symptoms as the sick fetus) [17]

Fetal Complications

  • Anemia in donor twin
  • Neurologic sequelae in the surviving twin due to death of the other twin [18]
  • Brain damage in the receiver twin
  • Respiratory, heart and digestive defects in the receiver twin due to high amniotic fluid levels [19]
  • Fetal death

Twin-to-Twin Transfusion Syndrome Incidence

Statistics show it to occur in around 15% of identical twin pregnancies [19].

What is anencephaly?

Anencephaly is a form of neural tube defect (NTD) that hampers the normal brain and skull development [1]. Babies affected by this condition are often stillborn or die within a few hours or days of birth. (more…)

Fetal Alcohol Syndrome (FAS)

Fetal Alcohol Syndrome (FAS)

What is fetal alcohol syndrome?

Fetal alcohol spectrum disorders (FASDs) are a group of potentially disabling congenital conditions that occur due to alcohol consumption by the mother during pregnancy, with fetal alcohol syndrome or FAS being the most severe among them [1]. Problems and complications associated with it include mental retardation, physical and facial deformities and learning difficulties [2]. (more…)

Hydrops Fetalis

Hydrops Fetalis Definition

Hydrops fetalis (also referred to as fetal hydrops or simply hydrops) is a serious complication characterized by severe edema (fluid buildup) in multiple body areas of a fetus or a newborn infant. [1] In most cases, it is first observed during the second trimester (week 13 to 28) [2], but can also occur during the first (week 1 to 12) and third trimesters (week 29 to 40). Hydrops is not a condition itself but is triggered by various other factors during pregnancy, which lead to serious developmental problems and even death. (more…)

Amniotic Band Syndrome

Amniotic Band Syndrome

What Is Amniotic Band Syndrome?

Amniotic band syndrome or ABS occurs due to a pregnancy complication in which the fetus gets entangled with string-like amniotic bands. It hampers the growth and development of the baby by restricting the blood supply to certain body parts. ABS often leads to physical disabilities as well as congenital deformities – facial (eye, nose), head, arm, finger, foot and toe . [1] (more…)
