The thoracic muscles and breasts are separated by sheets of connective tissue known as fascia.<\/div><\/p>\n\n\n\n

Fascia is a sheet of connective tissue, containing mostly collagen and its function is to attach, stabilize, enclose, and separates muscles and other internal organs.<\/p>\n\n\n\n

Deep to the skin, there are several layers of fascia and space we need to know about (from superficial to deep):<\/p>\n\n\n\n

  1. Superficial fascia<\/strong>. Consisting primarily of loose connective tissue, attaching the skin and overlying the breasts.<\/li>
  2. Submammary <\/strong>(or retromammary<\/strong>) space<\/strong>. A space filled by loose areolar tissue, separating the breast from the pectoralis major muscle and pectoral fascia<\/strong> (see below).<\/li>
  3. Pectoral fascia<\/strong>. Covering pectoralis major muscle.<\/li>
  4. Clavipectoral fascia<\/strong>. Covering pectoralis minor muscle.<\/li>
  5. Endothoracic fascia<\/strong>. Situated between the lungs and the thoracic wall, attaching it to the parietal pleura of the lung.
    • The suprapleural membrane <\/strong>is the superior continuation of the endothoracic fascia as it becomes more fibrous over the apices of the lungs (cupula).<\/li><\/ul><\/li><\/ol>\n\n\n<\/span>\n

      Breast implants can be inserted in different layers between the fasciae or muscles. <\/p>\n\n\n\n

      There are four surgical approaches to emplacing a breast implant:<\/p>\n\n\n\n

      1. Subglandular<\/strong>. Within the retromammary space<\/li>
      2. Subfascial<\/strong>. Within the pectoral fascia<\/li>
      3. Subpectoral<\/strong> (dual plane). Underneath the pectoralis major muscle, while releasing the inferior attachment of the muscle<\/li>
      4. Submuscular<\/strong>. Underneath the pectoralis major muscle, without releasing the inferior attachment of the muscle.<\/li><\/ol>\n<\/span>
