expand the medical history. Careful review of previous nasal surgery provides invaluable information to assess the patient’s candidacy for rhinoplasty.
Attention should be paid to the number of previous rhinoplasties, whether an open or closed approach was used, and the dates when these procedures were performed. It should also be noted whether or not the procedure was successful, along with reasons for failure if that is the case, and any perioperative complica­tions that may have occurred. Previous nasal traumas or nasal operations can alert the surgeon to potential structural abnormalities, such as septal fracture or depletion or exhaustion of local or distant gra material, so that these potential problems can be factored into the planning process.
Nasal obstruction is frequently caused by abnormalities of the nasal septum, na­sal valves, or inferior turbinates, which normally regulate nasal airow.
All nasal and upper respiratory symptoms or complaints should be thoroughly investigated; these problems are usually related to some anatomic structure or associated deformity. In patients who complain of frequent nasal obstruction, the cause is usually signicant septal deviations, dysfunction of the internal and/or external valves, and/or hypertrophied inferior turbinates. e latter, which are oen associated with a long history of allergic rhinitis, produce symptoms that are worse at night when the inferior turbinates become engorged. ese patients generally use antihistamines, local decongestants, and/or short courses of corti­costeroids once or twice a year. Such patients must be told that their symptoms of allergic rhinitis may persist for a long time and may even be exacerbated dur­ing the postoperative period.
Patients with a history of nasal surgery may have obstructions as a result of syn­echiae or scar contracture involving the internal structures of the nose.

Dysfunction of the nasal airway is frequently seen in secondary rhinoplasty pa­tients and should be carefully investigated.
Patients should also be questioned about other factors that could complicate the operative procedure, such as sinusitis, asthma, bronchitis, tobacco and alco­hol consumption, and illicit and prescription drug use. For example, medicines containing acetylsalicylic acid tend to increase the bruising and bleeding asso­ciated with surgery, whereas certain antidepressants may lead to perioperative hypertension. Smoking may increase the risk of postoperative wound healing complications and may prolong postoperative nasal obstruction, with persistent irritation of the respiratory tract.
PHYSICAL EXAMINATION
e physical examination identies correctable nasal deformities and is used to determine whether the patient’s goals and expectations are realistic. e surface anatomy of the nose directly reects the underlying framework. A systematic, detailed examination provides the surgeon with a list of problems from which to formulate the operative plan. Examination should begin with a full facial analysis to assess facial balance and the potential benet of adjunctive procedures. Next, the nasal structures are observed. Skin thickness and texture, nasal deviation, shape and width, alar rim morphology, tip denition, projection and rotation, nasal base width, and nostril shape should be thoroughly analyzed and docu­mented (see Chapters  and ).

e internal nasal examination includes speculum examination and dynamic maneuvers. Adequate lighting and instrumentation are requisite. In some in­stances, it may be necessary to perform this before and aer vasoconstriction of the nasal mucosa. It is essential for assessing and documenting the preoperative status of the functional airway and for discussing the potential strategies for al­tering nasal appearance and the potential benecial eects these changes may have on improving nasal airow (for example, spreader gras and dorsal width; alar contour gras and alar rim appearance).
Nasal obstruction at the internal valve may be evident by analysis of the external nose. Some patients may note improvement of nasal airow by pulling laterally on the cheek, mimicking the Cottle test.

e Cottle test is performed by applying lateral traction on the medial cheek at the level of the internal valve. Subjective improvement of nasal airow on the side tested may indicate nasal obstruction at the internal valve. Alternatively, a cotton-tipped applicator can be used to open the internal or external valve to evaluate for nasal obstruction at these sites.
With normal respiration, external valve collapse may not be present, but dynamic external valve collapse can be elicited by having the patient inspire forcefully.

Nasal strip test Cottle test
Gruber et al described the use of nasal strips to evaluate inspiratory function at the internal and/or external nasal valve. e nasal strip is applied to the middle third or lower third of the nose, and the patient reports whether this improves, worsens, or has no eect on nasal airow. is test can help predict whether sur­gical correction of nasal valvular dysfunction will improve airow.

Septal
perforation
Identication of preexisting synechiae, septal deformities, or perforations should be reported to the patient preoperatively to avoid mistaken blame later. Abnor­malities of the septum or turbinates are presented to the patient to allow discus­sion of surgical correction. (For a detailed description of the complete physical examination, see Chapter .)
Nasal obstruction is common among patients presenting for rhinoplasty. How­ever, many patients are unaware that they have this problem and may become more aware of symptoms postoperatively if these are le untreated.
Potential cartilage donor sites (especially in secondary rhinoplasty patients) are evaluated when necessary to allow preoperative discussion and justication of distant gra sites. In patients presenting for secondary rhinoplasty or who have undergone a previous septoplasty, it is important to assess for the presence of
Chapter  Preoperative Concepts for Rhinoplasty 71
https://t.me/medicina_free
septal cartilage. If septal surgery has been performed previously, a cotton-tipped applicator can be used to palpate the septum to assess for rigidity if septal carti­lage is still present or accidity if it has been harvested. Where septal cartilage has been harvested, it is important to estimate the width of the anterior septum or L-strut. is can be performed by using a cotton-tipped applicator in the domi­nant hand to sweep across the septum in a posterior to anterior direction toward the dorsum. e distance between the dorsal edge of the septum and where the posterior edge of the L-strut is encountered can be estimated.
Physical examination should focus on the skin envelope, the osteocartilaginous framework, internal nasal structures, and identication of potential cartilage donor sites. Evaluation of nasal airway function is included in the physical ex­amination.
PATIENT SELECTION
Aer a detailed history is obtained and physical examination is completed, the surgeon should be better able to render judgment as to whether the patient is a good candidate based on the patient’s goals and expectations, in conjunction with the deformities noted during physical examination. Emotional factors elicited in the history are also considered at this time. Patients presenting for aesthetic surgery during periods of signicant upheaval or emotional strain should not undergo surgery, even if they possess correctable anatomic deformities. Surgery should be delayed until the other aspects of their lives are stabilized.
Congruency between the patient’s and surgeon’s goals and expectations is critical to successful and satisfying outcomes from aesthetic surgery.
Ideal patients are secure, emotionally stable, well informed, and understanding of the limitations of rhinoplasty, and realistic in their expectations. e acro­nym SYLVIA describes the appropriate female rhinoplasty patient who is secure, young, listens, and is verbal, intelligent, and attractive.

Red Flags When Assessing Patients Suitability for Rhinoplasty
1. Minimum disgurement
2. Delusional distortion of the body image
3. An identity problem or sexual ambivalence
4. Confused or vague motives for wanting the surgery
5. Unrealistic expectations of change in life situations as a result of the surgery
6. A history of poorly established social and emotional relationships
7. Unresolved grief or a crisis situation
8. Present misfortunes blamed on physical appearance
9. Older neurotic man overly concerned about aging
10. A sudden anatomic dislike, especially in older men
11. A hostile, blaming attitude toward authority
12. A history of seeing physicians and being dissatised with them
13. e indication of paranoid thoughts
Conversely, patients who have unrealistic expectations, insecurities, and/or exces­sive concerns about minimal deformities will most likely be disappointed regard­less of the postoperative aesthetic improvement. Listed above are some red ags that may indicate that a patient has underlying psychological issues. Examples of these patients are categorized by the acronym SIMON, which refers to an indi­vidual who is single, immature, male, overly expectant, with narcissistic traits.
,
An emotionally unstable patient adversely inuences the relationship between the surgeon and the patient and constitutes the general basis of poor results.
Secondary rhinoplasty patients who express anger toward their previous surgeon or are actively involved in litigation, those desiring a result that is beyond the realm of the aesthetic norm (for example, wanting a dorsal hump created), and those with a controlling or confrontational personality should be approached with extreme caution and should not be operated on in most cases. e decision to proceed with or end the doctor-patient relationship should be made at the
Chapter  Preoperative Concepts for Rhinoplasty 73
https://t.me/medicina_free
completion of the assessment. Patients who are not good candidates should be told early in the process. Proceeding with imaging or further appointments will only make the process of ending the relationship more dicult and problematic.
Patients who express anger toward previous surgeons or who have personalities that are confrontational or controlling should not be operated on.
DIGITAL PHOTOGRAPHIC ANALYSIS
Standardized photography should be obtained for all patients preoperatively (see Chapter ). Photographic analysis is a key component of the secondary exami­nation. Subtle asymmetries and deformities are more easily identied on qual­ity photographs and with simultaneous evaluation of the deformity in multiple views. Photographs also serve as useful visual aids in the communication pro­cess between patient and surgeon. Multiple-view photographs allow patients a chance to more accurately demonstrate their concerns, improving the surgeon’s comprehension of the patient’s goals and expectations.
Photographs also provide a signicant contribution to the medical record by doc­umenting the preoperative and postoperative status of the patient. Good-quality photographs depend on proper positioning, cameras, lenses, and ashes. Every eort should be made to standardize techniques for the purpose of comparison between visits. Digital photography has made obtaining photographs of the pa­tient relatively easy, ecient, and cost eective. Additionally, it allows for easy storage and retrieval. We use a digital single-lens reex system with a minimum resolution of  3  pixels at  dpi, a  mm lens, and dual lighting with a blue background. e images are then stored in a database to allow high-quality printing, image manipulation, and retrieval.
