Accessory muscles of the anterior thoracic wall and axilla. Cadaveric, surgical and radiological incidence and clinical significance during breast and axillary surgery
Summary:
The present study aims to summarize the accessory muscles of the anterior thoracic wall
and axilla that can be encountered during breast and axillary surgery and record their
incidence and clinical significance. Moreover, the laterality of the atypical muscles is
highlighted and possible gender dimorphism is referred. Accessory anterior thoracic wall
muscles include: Langer’s axillary arch, sternalis muscle, chondrocoracoideus muscle,
chondroepitrochlearis, chondrofascialis, pectoralis minimus, pectoralis quartus and
pectoralis intermedius.
The anatomical, surgical and radiological literature has been reviewed and an anatomical
study on 48 Greek adult cadavers was performed. Literature review revealed that there are
accessory muscles of the anterior thoracic wall and axilla that have a significant incidence
that can be considered high and may, therefore, have clinical significance. For the most
common of these muscles, which are Langer’s axillary arch and sternalis muscle, the
cadaveric incidence is 10.30% and 7.67%, respectively. In the current cadaveric study,
accessory thoracic wall muscles were identified in two cadavers; namely a bilateral sternalis
muscle (incidence 2.08%) extending both to the anterior and posterior surface of the
sternum and a left-sided chondrocoracoideus muscle (of Wood) (incidence 2.08%).
Despite the fact that accessory anterior thoracic wall and axillary muscles are considered to
be rare, it is evident that the incidence of at least some of them is high enough to encounter
them in clinical practice. Thus, clinicians’ awareness of these anatomical structures is
advisable.
