Treatment for Paralyzed Diaphragm
Treatment for a paralyzed diaphragm depends on the cause of the paralysis, the severity of symptoms, whether one or both sides of the diaphragm are affected, and whether nerve function may recover over time. Some patients need only monitoring or treatment of an underlying condition, while others with persistent shortness of breath and functional limitation may benefit from surgery.
At Providence Saint John’s Health Center, treatment is individualized after confirming that diaphragm dysfunction is contributing to a patient’s symptoms and breathing limitations.
When Does a Paralyzed Diaphragm Need Treatment?
Not every patient with an elevated or paralyzed diaphragm requires treatment. The decision to intervene is based on symptoms, breathing function, imaging findings and the likelihood that diaphragm or phrenic nerve function may improve. Treatment becomes more important when diaphragm dysfunction causes persistent shortness of breath, limits activity, affects sleep or significantly interferes with daily life.
Observation and Treating the Underlying Cause
Patients with mild symptoms or a potentially reversible phrenic nerve injury may be monitored because diaphragm function can sometimes improve over time. When an underlying condition, injury or recent surgery has affected the phrenic nerve, treatment may initially focus on recovery and management of the underlying cause before surgery is considered.
Breathing and Supportive Therapy
Supportive treatment may include respiratory therapy, treatment of associated lung disease, physical conditioning and strategies to improve breathing efficiency. Selected patients with more extensive diaphragm weakness or breathing difficulty during sleep may also benefit from noninvasive ventilatory support. These approaches can improve breathing and daily function, although they do not restore contraction to a diaphragm that remains paralyzed.
Diaphragm Plication
Diaphragm plication is the primary surgical treatment for selected patients with persistent symptomatic diaphragm paralysis. The procedure stabilizes the weakened diaphragm in a lower, flatter position so that it no longer rises excessively into the chest or moves abnormally during breathing. This creates more room for the lung to expand and can improve the mechanical efficiency of breathing. Minimally invasive techniques, such as robotic surgery using the da Vinci Surgical System, improves patient recovery with less time required to sray in the hospital after the surgery.
What Does Diaphragm Plication Do?
During plication, the surgeon folds and secures the weakened portion of the diaphragm with sutures, placing it under tension and preventing excessive upward movement. The operation does not repair the phrenic nerve or cause the paralyzed diaphragm to contract again. Instead, it stabilizes the diaphragm so that the lung and the remaining respiratory muscles can function more efficiently.
Who May Benefit From Diaphragm Plication?
Diaphragm plication may be considered when persistent diaphragm paralysis causes significant shortness of breath, difficulty with exertion, symptoms when lying flat or measurable loss of respiratory function. Before recommending surgery, physicians evaluate whether the diaphragm is truly responsible for the patient’s symptoms and whether other heart, lung or neuromuscular conditions may be contributing. Imaging findings alone are not usually enough to determine whether surgery is appropriate.
Minimally Invasive and Robotic Diaphragm Plication
Diaphragm plication can be performed using traditional or minimally invasive surgical approaches. When appropriate, thoracoscopic or robotic techniques allow the surgeon to reach the diaphragm through small incisions in the chest and precisely place sutures that flatten and stabilize the weakened muscle. The surgical approach is selected based on the patient’s anatomy, previous operations, severity of dysfunction and other individual factors.
Minimally invasive thoracic surgery can reduce the amount of disruption to the chest wall compared with a traditional open operation while allowing the surgeon to directly address the mechanical problem caused by diaphragm paralysis. The goal remains the same regardless of approach: improve breathing mechanics by returning the diaphragm to a more favorable position.
What to Expect With Diaphragm Plication
Patients undergo a thorough evaluation before surgery to confirm the diagnosis, measure respiratory function and determine whether diaphragm plication is likely to improve symptoms. Testing may include pulmonary function studies, imaging and evaluation of diaphragm movement. The surgical and pulmonary teams also review the patient’s overall health and any other conditions that could affect breathing or recovery.
During Surgery
Diaphragm plication is performed under general anesthesia. The surgeon accesses the diaphragm, places the weakened muscle under appropriate tension and folds or secures it with sutures so that it remains in a lower, more stable position. This helps prevent the diaphragm from moving upward into the chest and allows the affected lung more room to expand.
Hospital Recovery
After surgery, patients are monitored while breathing and activity gradually increase. Recovery typically includes pain management, walking, breathing exercises and respiratory monitoring. A temporary chest drain may be used depending on the surgical approach and the individual patient.
Recovery After Diaphragm Plication
Recovery is gradual and varies depending on the surgical approach, a patient’s overall health and the severity of diaphragm dysfunction before treatment. Patients generally increase walking and daily activity over time while following temporary restrictions on strenuous activity or lifting. Breathing exercises and pulmonary rehabilitation may also be recommended to help maximize respiratory function.
Improvement is not always immediate. As surgical discomfort decreases and activity increases, patients may notice progressive improvement in shortness of breath, exercise tolerance and the ability to perform everyday activities. Follow-up allows the care team to assess symptoms, breathing function and recovery.
How Effective Is Diaphragm Plication?
Studies of appropriately selected patients have shown that diaphragm plication can provide meaningful and lasting improvements in shortness of breath, pulmonary function, and exercise tolerance. A recent systematic review involving more than 1,800 patients found that more than 70% returned to normal breathing after surgery, with a low rate of recurrent diaphragm dysfunction during follow-up. Other long-term studies have reported meaningful symptomatic or functional improvement in approximately 80% to 90% of patients. The degree of improvement varies and can depend on the duration and cause of paralysis, the patient’s overall lung function, and whether other medical conditions contribute to breathing difficulty.
Careful patient selection is important because diaphragm plication addresses the mechanical effects of paralysis rather than the underlying nerve injury. The greatest benefit is generally expected when symptoms and functional limitations can be clearly linked to the abnormal position and movement of the diaphragm.
What About Phrenic Nerve Repair or Diaphragm Pacing?
Some patients researching diaphragm paralysis may encounter treatments such as phrenic nerve reconstruction or diaphragm pacing. These highly specialized approaches are appropriate only for selected patients and are not routine alternatives to diaphragm plication for unilateral diaphragm paralysis.
Phrenic nerve reconstruction may be considered in selected injuries where restoring nerve function is technically possible. Diaphragm pacing is generally used in specific situations involving more complex neuromuscular or bilateral diaphragm dysfunction and requires an intact pathway between the nerve and diaphragm muscle. The most appropriate treatment depends on the cause and pattern of diaphragm dysfunction and the patient’s overall condition.
At Providence Saint John’s Health Center, patients with paralyzed diaphragm can be evaluated by pulmonary and thoracic specialists who consider symptoms, breathing function, diaphragm movement and the underlying cause of paralysis before recommending treatment. When surgery is appropriate, minimally invasive thoracic techniques may be used to stabilize the diaphragm and improve respiratory mechanics.
Our goal is not simply to correct an abnormal imaging finding, but to determine whether treatment can meaningfully improve breathing, activity and quality of life. Care is tailored to the individual patient, from observation and supportive management through advanced surgical treatment when needed.
