Planning elective operations on patients who smoke: survey of North American plastic surgeons.

Patient smoking status affects many aspects of plastic surgery, including patient selection, counseling, management, and outcomes. No specific recommendations for performing elective procedures on patients who smoke are available. The goal of this study was to determine the current practice standards and attitudes toward this often controversial topic. In September of 2000, 1600 members of the American Society for Aesthetic Plastic Surgery were sent questionnaires, 955 of which were returned. Questions elicited categorical answers, either dichotomous or multiple choice. Data were evaluated using logistic regression and the chi-square and binomial tests. Our results show that 60 percent (p < 0.01) of plastic surgeons routinely perform a less than optimal procedure on their patients who smoke. The survey measured willingness to perform various operative procedures on patients who smoke and types of smoking cessation aids offered. Of those physicians who require patients to quit smoking before surgery, only 16.7 percent (p < 0.01) would perform a nicotine test if they suspected noncompliance. Interestingly, 28.6 percent (p < 0.01) of the physicians responding admit to a smoking history, whereas only 1.5 percent (p < 0.01) continue to smoke, compared with the national smoking rate of almost 25 percent. Physicians who are previous smokers are less likely to offer smoking cessation aids than those who have never smoked, and the proportion not offering aids increases as the amount of previous smoking increases (p = 0.02). This study shows that a wide range of opinions exists on which elective surgical procedures should be performed on patients who smoke. Furthermore, the physician's prior smoking history influences this decision. No clear consensus exists on how best to treat patients who smoke who request elective surgeries. Although surgeons would prefer to operate on nonsmokers, they are faced with a significant population of patients who use tobacco. No clear consensus exists on how best to treat these individuals. Advancements in wound healing research and smoking cessation aids will provide more insight into this treatment dilemma.

Understanding the nasal airway: principles and practice.

LEARNING OBJECTIVES: After studying this article, the reader should be able to: 1. Describe the soft-tissue, cartilaginous, and bony anatomy of the nose. 2. Describe the anatomy and function of the nasal valves. 3. Discuss the governing physiologic principles responsible for airflow dynamics. 4. Discuss the various functions of the nose. 5. Demonstrate an appropriate evaluation of the nasal airway. 6. Discuss the differential diagnosis of nasal obstruction. 7. Discuss appropriate management options for nasal airway obstruction. The nose is a complex, multifunctional organ that requires respect and understanding from the rhinoplasty surgeon. The etiologic and pathologic characteristics of each patient's nasal airway problem determine the treatment of the nasal airway. Frequently, medical management is sufficient without operative intervention. Recent advances have shown that nasal valves in airway patency may play a more important role than the septum. The rhinoplasty surgeon's understanding of the anatomy and physiology of the nasal airway, along with the causes of obstruction, can pave the way for a proper evaluation and appropriate management of nasal airway problems. Lack of understanding can result in misdiagnosis and mismanagement. This article outlines current concepts of medical and surgical management of nasal airway problems and discusses in detail the key concepts and principles in the practical management of the nasal airway.

The alar contour graft: correction and prevention of alar rim deformities in rhinoplasty.

One of the most common problems affecting both the primary and secondary rhinoplasty patient is deformity of the alar rim. Typically, this deformity is caused by congenital malpositioning, hypoplasia, or surgical weakening of the lateral crura, with the potential for both functional and aesthetic ramifications. Successful correction and prevention of alar rim deformities requires precise preoperative diagnosis and planning. Multiple techniques of varying complexity have been described to treat this common and challenging problem. Over the past 6 years (1994 through 2000), the authors have employed a simple technique in 123 patients for alar retraction that involves the nonanatomic insertion of an autogenous cartilage buttress into an alar-vestibular pocket. Among the 53 patients who underwent primary rhinoplasty in this study, 91 percent experienced correction or prevention of alar notching or collapse. However, correction was achieved for only 73 percent of the patients who underwent secondary rhinoplasty; many of whom had alar retraction secondary to scarring or lining loss. In patients with moderate or significant lining loss or scarring, a lateral crural strut graft is recommended. The alar contour graft provides the foundation in the patient undergoing primary or secondary rhinoplasty for the reestablishment of a normally functioning external nasal valve and an aesthetically pleasing alar contour. This article discusses the anatomic and aesthetic considerations of alar rim deformities and the indications and the surgical technique for the alar contour graft.

Endoscopic transnasal approach for the treatment of medial orbital blow-out fracture: a technique for controlling the fractured wall with a balloon catheter and Merocel.

The authors repaired a medial blow-out fracture by using an endoscopic transnasal technique with a balloon catheter and Merocel packing in 17 subjects. The follow-up periods were from 6 weeks to 2 years, and averaged 6 months. The length of the operation was 50 minutes on average. The enophthalmos was corrected in seven of the eight patients. Supporting material for the fractured medial orbital wall was kept in place for 1 to 3 weeks. The mean volume of balloon inflation was 2 cc. The result was satisfactory. No complications resulted from the transnasal endoscopic technique. This endoscopic transnasal approach allows for a better aesthetic result because it eliminates external scarring and permits a direct approach to the medial orbital wall and has a superior visualization. A balloon catheter was used to support the fractured medial orbital fracture, which was adapted, ballooned, and then visualized using a radiopaque dye (Visipaque) in 11 cases. A postoperative computed tomographic scan revealed that this is a very useful method for controlling the status of the reduced orbital wall and eliminates the possibility of complications resulting from infection. A resected uncinate process was used as a bone graft material to repair the large defect in five cases. This method provides several advantages including a mucoperiosteal attached bone graft, working in the same operative field, and cost-effective surgical time. A transnasal endoscopic technique for medial orbital fracture is also very useful for releasing entrapment of the medial rectus muscle, because it directly pushes against the fractured wall and gives good exposure of the medial orbital wall.

Xanthelasma palpebrarum: a review and current management principles.

LEARNING OBJECTIVES: After studying this article, the participant should be able to: 1. Describe the differential diagnosis of xanthelasma palpebrarum. 2. Discuss the various nonsurgical and surgical treatment options and their advantages and disadvantages. 3. Describe the circumstances in which recurrence is most likely after treatment. Xanthelasma palpebrarum is the most common cutaneous xanthoma. It typically presents in middle-aged and older adults, most often around the eyelids. The diagnosis can often be made on clinical grounds alone. For the plastic surgeon, it is important to apply an algorithmic approach to the treatment of these lesions. Depending on the size and location, several different methods can be used to address this problem, ranging from simple excision, to laser treatment, to chemical peeling. This article addresses the underlying pathophysiology of xanthelasma and the currently accepted modes of treatment.

The deviated nose: optimizing results using a simplified classification and algorithmic approach.

The deviated nose presents a particular challenge to the rhinoplasty surgeon because, frequently, both a functional problem (airway obstruction) and an aesthetic problem must be addressed. An approach to the deviated nose is presented that relies on accurate preoperative planning and precise intraoperative execution of corrective measures to return the nasal dorsum to midline, restore dorsal aesthetic lines, and maintain airway patency. The principles of correction include wide exposure through the open approach, release of all deforming forces to the septum, straightening of the septum while maintaining an adequate dorsal and caudal strut, restoring long-term support, reducing the hypertrophied turbinates, and performing controlled stable percutaneous osteotomies. An operative algorithm is described that emphasizes simplicity and reproducibility, and case studies demonstrate the results that can be achieved with this approach.
