Joe’s pulmonologist continued with more tests. After a bronchoscopy, a procedure to look in the airway and lungs using a thin flexible tube, his doctor thought a collapsed trachea might be the cause. He was diagnosed with tracheobronchomalacia (TBM), where the walls of the airway are weak and collapse when a patient breathes or coughs. Because the condition is so rare, his pulmonologist suggested he seek surgical treatment at a specialized center and referred him to me. When Joe arrived at Temple University Hospital, I ordered a bronchoscopy to confirm TBM and determine the best course of treatment. His results showed some airway collapse but it was not severe, nor was he coughing, which is another prominent symptom of TBM. The problem runs deeper A CT scan of his chest showed his diaphragm, the main muscle that facilitates breathing, was slightly elevated on both sides. I sent him to get a sniff test to confirm my hunch. The sniff test uses x-ray video to see how your diaphragm moves when you inhale quickly. Normally when you sniff, the diaphragm moves down. If it moves upward on inhale, that signals dysfunction, which is what we saw on Joe’s test. An ultrasound ultimately revealed the true diagnosis: bilateral diaphragmatic paralysis, an uncommon condition.
Some patients can benefit from losing weight or starting a pulmonary rehab program to reduce the burden on the diaphragm. For those with an impaired quality of life like Joe, surgery can offer a long-term solution. If the cause is thought to be a viral infection, we recommend waiting six months to a year after infection as there are reports of the phrenic nerve recovering on its own. That did not happen for Joe, so in January 2023, he had surgery to correct the paralysis on his right diaphragm. Plication is a minimally invasive procedure performed robotically through small incisions to reshape the diaphragm by suturing it onto itself to make it more stiff and flat, allowing the lung more room to expand and therefore helping the patient breathe better. Following the first surgery on the right diaphragm, he could once again breathe while lying flat. He returned to some normal everyday activities with more ease. In telemedicine follow-up appointments, he noted that he still felt some resistance when drawing in a breath so we brought him back for surgery in October to correct the paralysis on his left side. He’s now breathing completely normally with no feeling of obstruction. He returned to work in January and is even running again.
