What is Poland Syndrome?
Poland Syndrome is a congenital condition of underdeveloped breasts, nipples, and/or chest muscles. The cause of Poland Syndrome is unknown, and it affects more men than women. Poland Syndrome is not the same in all patients. Some individuals have absent breast tissue, while others do not have part or complete absence of the chest muscle.
Am I a Candidate for Poland Syndrome Surgery?
Poland Syndrome most commonly affects men and sometimes affects women. In mild cases, the male’s chest may appear to be concave. In more severe cases, the breast, nipples, and even pectoralis muscles may be completely absent. Patients may also have a nipple or breast asymmetry.
Although these are discomforting characteristics for most individuals, Poland Syndrome is not likely to cause any functional disabilities. However, some patients describe that the non-Poland side is stronger for activities like pushups or pull-ups. Dr. Schwartz has extensive experience treating patients who have Poland Syndrome in Dallas. Some men will also have contralateral gynecomastia, which can promote more asymmetry between both breasts. Women will often need a breast augmentation (breast implants), fat grafting with or without liposuction to correct Poland Syndrome.
What to Expect During Your Examination for Poland Syndrome?
When you come into Dr. Schwartz’s office, he will want to go over a few things with you during this consultation appointment. Dr. Schwartz will examine the chest wall, chest contours, and skin elasticity. This will help him to create the treatment plan. He will also go over your medical history, lifestyle, and current health to make sure that you can safely undergo Poland Syndrome surgery.
Poland Syndrome can be treated at any age; however, it is usually addressed after puberty. Surgery might be performed at that time or delayed depending on the case.
Poland Syndrome Surgery Benefits
- Rebuild the wall chest or breast deformity, improve the contour of the chest, and gain self-esteem.
- Your surgery typically performed under sedation and may take about an hour to complete.
- Dr. Schwartz often employs multiple liposuction modalities such as high definition liposuction, power-assisted liposuction, and tumescent liposuction further to sculpt the chest in the correction of Poland syndrome.
- No drains are used during the surgery, which means your recovery period is often associated with minimal pain or discomfort, which can be managed with analgesics.
- The sutures used during your procedure are typically absorbable.
- Dr. Schwartz serves patients in the Greater Los Angeles area. He also sees patients from throughout California and out of the state/country. Dr. Schwartz’s staff assists patients out of Beverly Hills to arrange everything needed for the surgery.

How is a Poland Syndrome surgery performed?
The technique to correct Poland Syndrome will vary depending on various factors, including the severity of your condition. Such techniques include tissue expanders, implants, fat grafting, and muscle flaps. Most commonly, Dr. Schwartz uses a pectoral implant (pec implant) to correct Poland syndrome’s asymmetry. This implant replaces and fills up the pectoralis major muscle space and ensures that the chest area provides better symmetry. The surgery is typically set up through a mid-axillary approach so that your scars are concealed.
Traditionally, men are treated with customized chest implants and muscle flaps. Dr. Schwartz will provide a specific, individualized procedure plan to achieve the best cosmetic results. As with any surgical breast procedure, Dr. Schwartz provides specific aftercare instructions and close follow-up care to ensure the best results with a safe and healthy recovery.
Anesthesia for Poland Syndrome surgery
For your Poland Syndrome surgery, Dr. Schwartz will make sure that you are comfortable during the procedure. For this surgery, he will most commonly use local anesthesia with sedation to minimize discomfort, bleeding, and relieve anxiety related to undergoing a Poland Syndrome surgery.
Poland Syndrome surgery recovery
Dr. Schwartz will provide complete after-care instructions for the recovery period. Depending on the type of Poland Syndrome treatment you get, recovery time will vary. Most recovery takes between 2-6 weeks in total. Refraining from strenuous activity during recovery is important while the chest is healing.
Dr. Schwartz advises wearing compression garments after the surgery to avoid swelling or the buildup of fluid. This keeps the swelling in check and helps your skin conform to the new shape. At a follow-up appointment with Dr. Schwartz, he will let you know when all normal activities can be resumed.

- Unilateral Defect of Pectoralis Muscle and Syndactyly of the Hand
Signs & Symptoms
Associated symptoms and findings are extremely variable, including in rare cases in which more than one family member has been affected. For example, in some reported cases, one sibling has had all major features of the condition, while the other sibling has had only absence of pectoral muscle or hand involvement.
However, as noted above, Poland Syndrome is most commonly characterized by absence of chest wall muscles on one side of the body (unilateral) as well as involvement of the hand on the same side (ipsilateral). In approximately 75 percent of cases, such abnormalities affect the right side of the body.
In most affected individuals, there is absence of the sternal portion of the pectoralis major as well as absence of the pectoralis minor. The pectoralis major, a large muscle of the upper chest wall, arises from the breastbone (sternum), the collarbone (clavicle), and cartilages of the second to the sixth ribs; it acts on the joint of the shoulder, functioning to move the arm across the body. The pectoralis minor is a thin, triangular muscle beneath the pectoralis major. This muscle arises from the third to fifth ribs and functions to rotate the shoulder blade (scapula) and move it forward and down.
In some individuals with Poland Syndrome, there may also be unilateral absence of other regional muscles, such as certain large muscles of the back (latissimus dorsi) and/or a thin muscle of the chest wall that extends from ribs under the arm to the scapula (serratus anterior).
In some cases, associated abnormalities may include underdevelopment or absence of the darkened area around the nipple (areola) and the nipple and/or abnormal patchy hair growth under the arm (axilla). In addition, in affected females, there may be underdevelopment or absence of the breast and subcutaneous tissues.
Additional, variable bone defects may also be present in some individuals with Poland Syndrome. These may include underdevelopment or absence of certain upper ribs and the bars of cartilage (costal cartilages) by which the ribs are attached to the sternum. In addition, in some cases, there may be abnormal elevation and/or underdevelopment of the shoulder blade (scapula), limited movement of the arm on the affected side, and the development of a lump at the base of the neck due to elevation of the scapula (a condition known as Sprengel deformity). (For more information, please choose “Sprengel” as your search term in the Rare Disease Database.)
As noted above, most individuals with Poland Syndrome also have involvement of the hand on the affected side of the body. Certain bones of the fingers (phalanges) are underdeveloped or absent, resulting in abnormally short fingers (brachydactyly). In addition, in most cases, there is webbing (syndactyly) of certain fingers, particularly the index and middle fingers. In addition, in some cases, affected individuals may have abnormal shortening of the arm, with underdevelopment of the bones on the thumb and pinky sides of the forearm (i.e., radius and ulna).
Poland Syndrome
Poland Syndrome is a rare condition that is evident at birth (congenital). Associated features may be extremely variable from case to case. However, it is classically characterized by absence (aplasia) of chest wall muscles on one side of the body (unilateral) and abnormally short, webbed fingers (symbrachydactyly) of the hand on the same side (ipsilateral). In those with the condition, there is typically unilateral absence of the pectoralis minor and the sternal or breastbone portion of the pectoralis major. The pectoralis minor is a thin, triangular muscle of the upper chest wall; the pectoralis major is a large, fanlike muscle that covers most of the upper, front part of the chest. Affected individuals may have variable associated features, such as underdevelopment or absence of one nipple (including the darkened area around the nipple [areola]) and/or patchy absence of hair under the arm (axilla). In females, there may be underdevelopment or absence (aplasia) of one breast and underlying (subcutaneous) tissues. In some cases, associated skeletal abnormalities may also be present, such as underdevelopment or absence of upper ribs; elevation of the shoulder blade (Sprengel deformity); and/or shortening of the arm, with underdevelopment of the forearm bones (i.e., ulna and radius). Poland Syndrome affects males more commonly than females and most frequently involves the right side of the body. The exact cause of the condition is unknown.

According to reports in the medical literature, an overwhelming majority of cases appear to occur randomly for unknown reasons (sporadically) in the absence of a family history. However, in some very rare cases, familial patterns have been reported, including occurrence of the condition in a parent and child and in siblings born to unaffected parents. Some researchers suggest that apparently familial cases may result from inherited susceptibility to a certain event or anomaly (such as early interruption of blood flow) that may predispose to the syndrome (see directly below).
Poland Syndrome is sometimes referred to as Poland sequence. A “sequence” (or anomalad) refers to a pattern of malformations derived from a single anomaly. According to some investigators, the primary defect in Poland Syndrome may be impaired development of a certain artery or other mechanical factors that may result in diminished or interrupted blood flow during early embryonic growth. The term “Subclavian Artery Supply Disruption Sequence” has been suggested for a group of conditions that may occur due to disruption of blood flow through particular arteries (i.e., subclavian artery, vertebral artery, and/or their branches) at or around the sixth week of embryonic development. Such conditions include Poland Syndrome, Moebius Syndrome, Klippel-Feil Syndrome, and Sprengel deformity. The specific pattern of defects that results is thought to depend on the particular site and degree of the diminished blood flow. (For further information on Moebius Syndrome, see the “Related Disorders” section below. For more on Klippel-Feil Syndrome and Sprengel deformity, choose “Klippel” or “Sprengel” as your search term in the Rare Disease Database.)
Poland Syndrome was named for the investigator (Poland A) who initially described the condition in 1841. According to reports in the medical literature, Poland Syndrome appears to be three times as common in males as females. Estimates of its incidence have ranged from approximately one in 10,000 to one in 100,000 individuals. (Incidence refers to the number of new cases in a particular period.)
As noted above, Poland Syndrome affects the right side of the body in approximately 75 percent of cases. In 1998, investigators reported what was thought to be the first known case in which both sides of the body have been affected (bilateral). Researchers described a young girl with bilateral absence of pectoralis muscle, symmetric chest wall deformity, and bilateral hand involvement.
Symptoms of the following disorders may be similar to those of Poland Syndrome. Comparisons may be useful for a differential diagnosis:
Several investigators have reported cases in which the features of Poland Syndrome occur in association with Moebius Syndrome. Known as “Poland-Moebius Syndrome,” such cases are characterized by facial paralysis due to impairment of the sixth and seventh cranial nerves (i.e., Moebius Syndrome) associated with the chest wall defects and/or hand malformations (symbrachydactyly) typically seen in Poland Syndrome. Moebius Syndrome may be characterized by a “masklike”, expressionless face; inability to conduct certain eye movements; drooping of the upper eyelids (ptosis); underdevelopment and/or limited mobility of the tongue; poor sucking and swallowing; and speech impairment. Additional features may include a deformity in which the foot is twisted out of shape or position (clubfoot); various other limb defects; mild mental retardation; and/or other abnormalities. Moebius Syndrome typically appears to occur randomly for unknown reasons (sporadically). As mentioned above (see “Causes”), some investigators suggest that the condition may result from early disruption of blood flow through particular arteries during embryonic development (i.e., Subclavian Artery Supply Disruption Sequence). (For more information on this condition, choose “Moebius” as your search term in the Rare Disease Database.)
Oromandibular-Limb Hypogenesis Syndromes is a term sometimes used to describe a group of rare conditions characterized by underdevelopment (hypogenesis) of the mouth and jaw (oromandibular) areas; parts of the embryo that eventually develop into the arms, legs, hands, and feet (the limb buds); and possibly other areas in the developing embryo. This “community” of so-called face-limb malformation syndromes includes Moebius Syndrome, Charlie M Syndrome (see below), Hanhart Syndrome, and others. (For more on Hanhart Syndrome, use “Hanhart” as your search term in the Rare Disease Database.) Such conditions typically appear to occur randomly for unknown reasons (sporadically) and may be characterized by extremely variable clinical features. Some researchers believe that these are overlapping syndromes or disease variants representing a spectrum of malformations caused by environmental and/or other factors. As noted earlier, some experts suggest that certain Oromandibular-Limb Hypogenesis Syndromes, such as Moebius Syndrome, may be due to early disruption of blood flow in certain arteries due to various mechanical factors (i.e., Subclavian Artery Supply Disruption Sequence).
Charlie M Syndrome is a rare condition characterized by certain distinctive facial and limb malformations. According to reports in the medical literature, there may be disagreement differentiating between Charlie M Syndrome and various other face-limb malformation syndromes. The syndrome is characterized by widely spaced eyes (ocular hypertelorism); a broad nose and small mouth; incomplete closure of the roof of the mouth (cleft palate); an abnormally small jaw (micrognathia); facial nerve paralysis in some cases; absent or cone-shaped front teeth (incisors); and variable, asymmetric abnormalities of the fingers and toes. The condition typically appears to occur randomly for unknown reasons.
A number of other conditions may be characterized by certain chest wall defects, hand malformations, and/or other findings similar to those associated with Poland Syndrome. (For further information on such disorders, use the exact disease name in question as your search term in the Rare Disease Database.)
The diagnosis of Poland Syndrome is usually made at birth based upon characteristic physical findings, a thorough clinical evaluation, and a variety of specialized tests. Such tests may include advanced imaging techniques, such as a CT scan that can determine the extent to which the muscles may be affected. During CT scanning, a computer and X-rays are used to create a film showing cross-sectional images particular organs or structures within the body. X-ray studies may be used to help identify and characterize specific abnormalities in the hands, forearms, ribs, and/or shoulder blades.
The treatment of Poland Syndrome is directed toward the specific symptoms that are apparent in each individual. Treatment may require the coordinated efforts of a team of specialists. Plastic surgery may be performed to rebuild the chest wall and to graft ribs into their proper places. In females, plastic surgery may also be performed to construct a breast mound. In some cases, surgery may also be performed to help correct skeletal abnormalities affecting other areas of the body such as the hands. Physical therapy may also be prescribed to help improve any limitations of motion.
Genetic counseling will be of benefit for affected individuals and their families. Other treatment for this disorder is symptomatic and supportive.

Population, symptoms and causes
Most often, the Poland Syndrome’s malformation is limited to the pectoralis major muscle, but in some cases, it can be associated to other types of deformations. In 20% of cases, it is associated with atrophy of the hand and upper arm on the same side. The chest and ribcage may also present associated abnormality (atrophy, fibrosis, Pectus).
Poland Syndrome’s origin is poorly known. A hypothesis is that this syndrome is due to an abnormality of formation of the subclavicular artery at the embryonic stage, which would induce a partial development, or lack of development, of the pectoralis major muscle during pregnancy.
Type 1
The subcutaneous plan is correct (fat and skin thickness hide part of the ribs, in women the breast remains fully or partially developed).

Type 2
The subcutaneous plane is more atrophic (ribs more visible, partial or total absence of breasts in women).

TYPE 3
Atrophy of the subcutaneous plane associated with deformity of the thoracic cage.

Functional Impact
Its functional impact is low, even in the case of atrophy of the hand, but the psychological impact, due to the aesthetic appearance, may be very damaging in terms of self-esteem and social relationships.
