(b) The lung fields show multiple
atelectatic changes (red arrows) and bilateral pleural effusion.
Generally, cartilage is used as a graft material in case of
atelectatic ears, high risk perforation and cholesteatoma.

atelectatic ear," Operative Techniques in Otolaryngology--Head and Neck Surgery, vol.
Furthermore, the intense postoperative pain often leads to the use of narcotics to be controlled, reducing the respiratory function (by suppressing the respiratory drive) causing the reduction of pulmonary hygiene and an increased number of
atelectatic areas.
An alternate hypothesis has been proposed where reperfusion injury results in reexpansion pulmonary edema.[6] Absent ventilation and hypoperfusion owing to atelectasis leads to severe hypoxia of the
atelectatic lung.
IS group patient tried to achieve their pre-operative level of inspiratory effort and hence resulted in good expansion of lungs, decreased cases of
atelectatic respiratory complications and pulmonary oedema.
Recruitment of
atelectatic lung units is an integral goal of mechanical ventilation, but human lungs are not balloons--they are fractal branches and cannot be perfectly inflated with a constant volume at a constant rate.
Some histological sections exhibited catarrhal bronchitis and
atelectatic changes in association with pronounced eosinophilic granulomatous alveolitis.
Round Atelectasis.--Specimens showing
atelectatic lung with apparent fibrosis and overlying pleural fibrosis, especially in patients with a history of pleural effusions, should prompt consideration of round atelectasis.
PET/CT enabled better differentiation between hypermetabolic tumors and
atelectatic lung parenchyma or areas of adjacent pneumonitis, as previously reported [27] (Figures 6(a) and 6(b)).
Atelectatic lungs have been shown to be re-opened using high inspiratory pressures and kept open with high levels of PEEP.
In 1(6.6%) of the patients, the
atelectatic area was clearly seen both in MRI and CT.
