Greater losses in tip projection using the lage excision and postsurgical nasal tip deformities, the use of open approach were attributed to the greater disruption of 663 Complications in Rhinoplasty secondary support mechanisms associated with external rhino- 83. The authors concluded that the septum likely plays a far more significant role in nasal tip support than previously Deformity believed and is likely equal in importance to the lower lateral cartilages and their soft tissue attachments in providing nasal For decades, rhinoplasty surgeons relied upon aggressive exci- tip support. The excisional technique, ondary support from the septal cartilage-upper lateral carti- commonly called the “cephalic trim,” removes nearly the entire lage complex and various soft tissue attachments, the paired cephalic border of the lateral crus and is still widely practiced alar cartilages themselves are the ultimate determinants of today. It is the mirror-image alar cartilages, sepa- delayed tip deformities, many cosmetic surgeons still regard rated anatomically into lateral and medial aura by the nasal the cephalic trim as a mandatory step in practically any cos- domes, which determine lobular shape as governed by their metic nasal surgery. In theory, surgically narrowing the lateral spacing, angulation, projection, symmetry, alignment, and crus should flatten a convex (bulbous or wide) crural cartilage size. By definition, any surgical procedure designed to and produce a desirable reduction in tip fullness. In addition, enhance tip contour must also alter the shape and/or spatial modest scar contracture between the lateral crural remnant relationships between the nasal tip cartilages.

However, when partial crural excision mary or secondary tip support if the cosmetic outcome is to leaves a remnant that is too weak to meet structural demands remain predictable, stable, and reproducible. Moreover, the or too pliable to resist deformation by the forces of wound heal- surgical plan should also anticipate future losses in tip sup- ing, an uncontrolled collapse is initiated and a plethora of tip port resulting from both age-related deterioration and pro- deformities ultimately arise, particularly when septal support is gressive “shrink-wrap” contracture.

When these susceptible Perhaps, the most common nasal tip deformity resulting from noses are also subjected to further structural compromise with the cephalic trim technique is excessive narrowing or pinching cartilage excision, the cosmetic and functional consequences of the nasal tip lobule. The anatomic hallmark of can be devastating, particularly when progressive “shrink- lobular pinching is excessive concavity of the lateral crus. Likewise, surgically sion of the convex cephalic margin leads to a loss of longitudi- mediated fibrotic thickening of the skin-soft tissue envelope, nal rigidity, a flail and concave crural remnant, and eventual which obscures tip definition and adds additional structural collapse of the lower nasal sidewall.

Know that the pregnant woman is predisposed to deep venous thrombosis due to venous obstruction and a hypercoagulable state order 100mg danazol amex. Co n s i d e r a t i o n s T his 19-year-old woman at 20 weeks’ gestation complains of the acute onset of severe dyspnea and pleurit ic chest pain. The physical examinat ion confirms respira- tory distress due to tachycardia and tachypnea. The lungs are clear on auscultation, and the patient does not complain of cough or fever, which rules out reactive airway disease or significant pneumonia. The patient has significant hypoxia with oxygen saturation of 89%, which translates to a partial pressure of 58 mm H g (life-threatening). The test has been shown to have a good negative predictive value, making it useful in ruling out pulmonary embolism if negative. H owever, since an elevated D -dimer level is normally found in pregnant patients, the assay would have limited value in this case. If the imaging confirms pulmonary embolism, then the patient should receive ant icoagulat ion to help st abilize t he clot and decrease the likelihood of fur- ther venous thromboembolism. Oxygen is the most important substrate for the human body, an d even 5 or 10 minutes of severe hypoxemia can lead to devastating consequences.

Pulse oximetry and arterial blood gas studies should be ordered while informat ion is gat hered during t he hist ory and physical. Meanwhile, t he physical examinat ion should be directed at t he heart and lung evaluat ion. The lungs should be auscultated for wheezes, rhonchi, rales, or absent breath sounds. An arterial blood gas should be obtained to assess for hypoxemia, carbon dioxide retention, and acid– base status. These findings should be evaluated in the context of the physiological changes in pregnancy (see Table 15– 1). A chest radiograph should be performed rather expedi- tiously to differentiate cardiac versus pulmonary causes of hypoxemia. A large car- diac silhouette may indicate peripartum cardiomyopathy, which is treated by diuretic and inotropic therapy; pulmonary infiltrates may indicate pneumonia or pulmonary edema. A clear chest radiograph in the face of hypoxemia suggests pulmonary embo- lism, although early in the course of pneumonia, the chest x-ray may appear normal. The diagnosis of pulmonary embolism may be made presumptively on the basis of high clinical suspicion, hypoxemia, and a clear chest x-ray.
