Abstract
OBJECTIVE: Description of a novel technique to surgically correct (asymmetric) pectus carinatum and other chest deformities using a metal bar without fixation to the ribs. INDICATIONS: Severe thoracic deformity, extensive psychological strain, social isolation, pain and respiratory complaints. Pseudarthrosis or insufficient correction of a thoracic deformity after prior surgery. Distinctive deformities. CONTRAINDICATIONS: Acute infections. Postoperative intrathoracic scaring in revision cases can be challenging. SURGICAL TECHNIQUE: One-lung ventilation is used. Through two 3-4 cm long bilateral incisions to the thorax, an introducer is guided into the thorax under thoracoscopic supervision and then guided through an intercostal space out of the thorax again. A 1 cm presternal incision is performed and nylon threads are attached to the introducer bilaterally. Then the preshaped metal bar can be placed following the nylon threads. Once the metal bar is placed, the deformity is instantly corrected. Bilateral stabilizers are fixed with wire cerclage. Fixation on the ribs is not necessary. POSTOPERATIVE MANAGEMENT: Postoperative thorax x‑ray. Intensive ventilation exercises. Implant removal after 2-3 years. RESULTS: The technique was used in 10 primary pectus carinatum or combined pectus carinatum and excavatum deformities as well as in 6 revision cases (3 female, 13 male, age 13-32 years). Follow-up ranged from 3-15 months postoperatively. Cosmetic results were excellent. Revision surgery required in 2 patients (one rib fracture and one local implant irritation).
