What does decortication mean?
Decortication is the removal of an outer layer — literally a stripping away of bark, husk, or cortex. Its dominant modern use is surgical: decortication describes an operation in which a restrictive layer of fibrous tissue is peeled off an organ, classically the lung, where thickened scar tissue from infection or inflammation can trap the organ and prevent it from expanding. By freeing the lung from this rigid shell, the procedure restores breathing function. The word also appears in agriculture and materials processing for the husking or peeling of seeds, grains, and plant fibres, though this sense is less common today. Formal and technical in register, decortication derives from Latin cortex, meaning bark or rind, via the verb decorticare, to strip of bark. It should not be confused with decoration, which despite a similar appearance means nearly the opposite — adding ornament rather than removing a surface layer.
The surgical removal of the cortex or fibrous outer layer of an organ, especially the removal of scar tissue enclosing the lung.
"Decortication allowed the collapsed lung to re-expand against the chest wall."
Most frequently encountered as 'pleural decortication' in thoracic surgery.
The stripping or husking of bark, seed coats, or other outer coverings, especially in the processing of plants and fibres.
"Mechanical decortication separates the valuable bast fibre from the flax stem."
Usually uncountable when referring to the procedure in general; the plural appears mainly when discussing multiple distinct operations or cases.
"The registry recorded all decortications performed at the hospital over the decade."
Despite sounding like 'decoration,' decortication is the exact opposite — it's surgery that strips away, freeing a lung literally trapped in scar tissue.

Etymology of decortication
Decortication comes from the Latin verb decorticare, meaning to strip off bark, formed from de- ('away from') and cortex ('bark' or 'outer shell'). The term entered English in the early modern period, initially in botanical and agricultural contexts describing husking and barking, before acquiring its principal medical sense as surgery advanced in the nineteenth century. It shares its Latin root cortex with cognates such as cortical and corticosteroid.
