Residency programs have reported development of curriculums to increase safety and effciency . During periods of inactiv- ity, biweekly practice of 1 h has been shown to retain robotic surgical skills . Tooth guards can be helpful in protecting the maxillary dentition from damage as well as protecting the tongue from being lacerated by the lower incisor teeth during suspension laryngoscopy (Fig. In a sur- vey taken by 45 surgeons, exposed arterial vessels in the oropharynx are most commonly managed intraoperatively with surgical clips (93. The use of different forms of energy for cut- ting and ablating tissue is usually dependent on the surgeon and institution. The radiofrequency needle had the most favorable cutting width and smaller coagulation defects in that study. So the larger vessels such as the dorsal lingual artery importance of careful, layer-by-layer dissection require vascular clip application. Any exposed artery should be clipped and/or covered with adjacent soft tis- sue when possible. The group with concurrent surgery tumor resection, then re-resection can be per- had a 9.

Fibrosis or scarring of lung results in a combi- nation of the de-stabilizing forces resulting in Pulmonary collapse or atelectasis is defined as fibrotic or cicatrical collapse. Atelectasis may be present at birth (atelectasis neonatorum) due to failure of the lung • Obstructive (resorption collapse): Occurs due to to expand, or may occur anytime during life resorption of air distal to the obstruction in the (acquired atelectasis), which occurs due to absorp- bronchi. The site of obstruction could be central tion of air secondary to obstruction, compression, or peripheral. The factors maintaining normal lung expansion are Central obstructive collapse (Collapse due to the balance of mechanical and surface forces. The obstruction of a major bronchus) chest wall, physico-mechanically coupled by surface Peripheral Obstructive Collapse (Collapse forces through the pleurae, is essential for normal with a patent bronchus) lung expansion. The normal refractile properties of • Fibrotic collapse (contraction collapse or cicatrical the lung will cause them to collapse if dissociated collapse): Occurs due to fibrosis or scarring of the from the chest wall. Disruption of these properties can lead to lung • Relaxation or compressive collapse: Occurs from instability and collapse. Thus, the following factors, alone or in combination relaxation of the lung due to pleural disease like will result in collapse. Usual radiological signs of collapse result from Expansion of a collapsed lobe can occur after the airlessness of the lung causing opacification and obstruction is resolved and ventilation restored. However, the lung may never expand even after the Each segment or lobe of the lung, when collapsed obstruction is relieved. Upper lobe collapse may obli- clinical situations such as postoperative or critically terate the superior mediastinal border. However, in ill cases, inflammatory secretions, mucous or blood complete upper lobe collapse, prolapse of the apical may pool in the central bronchi. These are not segment of the lower lobe can restore the silhouette cleared due to a diminished cough reflex, reduced diaphragmatic motion and pain, resulting in absorp- tion of air distal to the obstruction. Negative pressure beyond this obstruction may pull the secretions peripherally occluding the smaller bronchi and absorption of the remaining air. Collapses in the postoperative period and in the critically ill patients thus occur due to mucus plugging of the central or peripheral bronchi and often reverse rapidly. Scott (1925) therefore postulated bronchial obstruction due to a reflex nervous stimulus to explain the dramatic re- expansion. The degrees of compensatory • Shift of fissure mechanisms vary to a great extent and depend on • Shift of hilum the degree of collapse, partial or complete.

Note the right paratracheal lucency, Luftsichel sign due to lower lobe hyperinflation interposing between mediastinum and collapse upper lobe Fig. Lower lobe collapse does not obliterate the cardiac borders (negative silhouette sign), and causes a retro-cardiac triangular opacity when collapsed completely (Fig. Lower lobe collapse sometimes results in an additional para-tracheal opacity due to displacement of superior mediastinal structures ("superior triangle" sign of lower lobe collapse). Collapse of whole lung results in opacification of hemithorax with shift of mediastinal structures to the same side (Fig. The "double lesion " sign results from collapse of two segments or lobes of the lung, which cannot be explained by one obstructive lesion, and is useful to exclude a malignant lesion. The reduction in breath sounds and voice sounds is due to obstruction of the bronchial lumen.
