  • Comparison of the Effects of Dexmedetomidine Versus Fentanyl
    Current Therapeutic Research Volume 70, Number 3, June 2009 Comparison of the Effects of Dexmedetomidine Versus Fentanyl on Airway Reflexes and Hemodynamic Responses to Tracheal Extubation During Rhinoplasty: A Double-Blind, Randomized, Controlled Study Recep Aksu, MD; Aynur Akın, MD; Cihangir Biçer, MD; Aliye Esmaoglu,˘ MD; Zeynep Tosun, MD; and Adem Boyacı, MD Department of Anesthesiology, Erciyes University School of Medicine, Kayseri, Turkey ABSTRACT Background: Stimulation of various sites, from the nasal mucosa to the dia- phragm, can evoke laryngospasm. To reduce airway reflexes, tracheal extubation should be performed while the patient is deeply anesthetized or with drugs that do not depress ventilation. However, tracheal extubation during rhinoplasty may be dif- ficult because of the aspiration of blood and the possibility of laryngospasm. Dexmede- tomidine and fentanyl both have sedative and analgesic effects, but dexmedetomidine has been reported to induce sedation without affecting respiratory status. Objective: The aim of this study was to compare the effects of dexmedetomi- dine and fentanyl on airway reflexes and hemodynamic responses to tracheal extuba- tion in patients undergoing rhinoplasty. Methods: This double-blind, randomized, controlled study was conducted at the Erciyes University Medical Center, Kayseri, Turkey. Patients classified as Ameri- can Society of Anesthesiologists physical status I or II who were undergoing elective rhinoplasty between January 2007 and June 2007 with general anesthesia were eli- gible for study entry. Using a sealed-envelope method, the patients were randomly divided into 2 groups (20 patients per group). Five minutes before extubation, pa- tients received either dexmedetomidine 0.5 μg/kg in 100 mL of isotonic saline or fentanyl 1 μg/kg in 100 mL of isotonic saline intravenously.

  • Rhinoplasty and Septorhinoplasty These Services May Or May Not Be Covered by Your Healthpartners Plan
    Rhinoplasty and septorhinoplasty These services may or may not be covered by your HealthPartners plan. Please see your plan documents for your specific coverage information. If there is a difference between this general information and your plan documents, your plan documents will be used to determine your coverage. Administrative Process Prior authorization is not required for: • Septoplasty • Surgical repair of vestibular stenosis • Rhinoplasty, when it is done to repair a nasal deformity caused by cleft lip/ cleft palate Prior authorization is required for: • Rhinoplasty for any indication other than cleft lip/ cleft palate • Septorhinoplasty Coverage Rhinoplasty is not covered for cosmetic reasons to improve the appearance of the member, but may be covered subject to the criteria listed below and per your plan documents. The service and all related charges for cosmetic services are member responsibility. Indications that are covered 1. Primary rhinoplasty (30400, 30410) may be considered medically necessary when all of the following are met: A. There is anatomical displacement of the nasal bone(s), septum, or other structural abnormality resulting in mechanical nasal airway obstruction, and B. Documentation shows that the obstructive symptoms have not responded to at least 3 months of conservative medical management, including but not limited to nasal steroids or immunotherapy, and C. Photos clearly document the structural abnormality as the primary cause of the nasal airway obstruction, and D. Documentation includes a physician statement regarding why a septoplasty would not resolve the airway obstruction. 2. Secondary rhinoplasty (30430, 30435, 30450) may be considered medically necessary when: A. The secondary rhinoplasty is needed to treat a complication/defect that was caused by a previous surgery (when the previous surgery was not cosmetic), and B.

  • Surgical Management of Nasal Airway Obstruction
    Surgical Management of Nasal Airway Obstruction John F. Teichgraeber, MDa, Ronald P. Gruber, MDb, Neil Tanna, MD, MBAc,* KEYWORDS Nasal obstruction Nasal breathing Septal deviation Nasal valve narrowing Turbinate hypertrophy KEY POINTS The management and diagnosis of nasal airway obstruction requires an understanding of the form and function of the nose. Nasal airway obstruction can be structural, physiologic, or a combination of both. Anatomic causes of airway obstruction include septal deviation, internal nasal valve narrowing, external nasal valve collapse, and inferior turbinate hypertrophy. Thus, the management of nasal air obstruction must be selective and carefully considered. The goal of surgery is to address the deformity and not just enlarge the nasal cavity.
