Endoscopic Management of Sinonasal Hemangiopericytoma

Objective. Sinonasal hemangiopericytomas (SNHPCs) are rare perivascular tumors with low-grade malignant potential. Traditionally, these tumors have been treated with open approaches such as lateral rhinotomy, Caldwell-Luc, or transfacial approaches. Increased experience with endoscopic management of benign and malignant sinonasal tumors has led to a shift in management of SNHPC. The authors present their experience in the largest series of patients with SNHPC managed endoscopically. Study Design and Setting. Case series at a tertiary care medical center. Subjects and Method. A retrospective chart review of all patients undergoing endoscopic management of SNHPC at the University of Miami between 1999 and 2008 was conducted. All endoscopic resections were performed with curative intent. Results. Twelve patients with the diagnosis of SNHPC were treated endoscopically. Mean age was 62.5 years (range, 51-83 years). There were 6 men and 6 women. The mean follow-up was 41 months (range, 15-91 months). Seven (58.3%) presented with nasal obstruction, whereas 4 (41.6%) had epistaxis as their initial presenting symptom. Preoperative angiography or embolization was not performed in any case. Mean estimated blood loss was 630 mL (range, 100-1500 mL). Six patients underwent endonasal endoscopic anterior skull base resection; 4 had complete endoscopic resection all with negative margins. None underwent postoperative adjuvant treatment. No recurrence or metastatic disease was observed in this patient population. Conclusion. Endoscopic management of SNHPC is a feasible approach and did not compromise outcomes in this experience. In this series, familiarity with advance endoscopic sinus surgery was necessary to manage these patients. Postoperative adjuvant therapy was not necessary in this cohort.

Modified subtotal lothrop procedure for extended frontal sinus and anterior skull base access: A cadaveric feasibility study with clinical correlates

Objective The endoscopic modified Lothrop procedure (EMLP) is an established approach for recalcitrant frontal sinus disease and anterior skull base exposure. However, in select cases, this technique may involve unnecessary resection of sinonasal structures. In this study, we propose a modification of the EMLP, termed the modified subtotal-Lothrop procedure (MSLP), to access the anterior skull base and complex frontal sinus disease for which access to the bilateral frontal sinus posterior table is required. Methods A cadaveric dissection with photo documentation was performed at an academic medical center on four cadaver heads using standard endoscopic techniques to demonstrate the MSLP and its feasibility. Results The endoscopic MSLP allowed ample access for instrumentation in each of the dissections using a 30- or 70-degree endoscope. Adequate bilateral access to the posterior table of the frontal sinus was gained in all cases without the need for dissection of the contralateral frontal sinus recess (FSR). Conclusion The MSLP appears to be a feasible technique for exposure of the anterior skull base and accessing complex frontal sinus pathology. This modification provides similar anterior skull base exposure and surgical maneuverability as the EMLP while limiting surgical dissection to one FSR, thereby preserving as much of the natural mucociliary drainage pathways as possible.

The Role of Alternative Medicine in Rhinology

Complementary and alternative medicine (CAM) includes treatments from traditional Chinese medicine, homeopathy, naturopathy, herbal medicine, Ayurvedic medicine, mind-body medicine, chiropractic or osteopathic manipulations, and massage. More than 40% of patients in the United States use CAM, with 17% of CAM use related to otolaryngology diagnoses, but nearly half of CAM users do not communicate their use of these medications to their physicians. Perioperative risk of bleeding is a particular concern in surgical specialties, and knowledge of these therapies and their potential adverse effects is critical.

Community‐acquired methicillin‐resistant Staphylococcus aureus in nasal vestibular abscess

Community‐acquired methicillin‐resistant Staphylococcus aureus (MRSA) is a recognized entity that is increasingly responsible for skin and soft tissue infections. However, it is not the usual pathogen isolated in nasal vestibular abscess.

Biomaterials in Rhinology

Introduction Many different kinds of rhinologic biomaterials, both nonabsorbable and absorbable, have been developed over the years to improve outcomes following endoscopic sinus surgery (ESS) for patients with chronic rhinosinusitis. In particular, these products have been designed to prevent postoperative bleeding, optimize the wound healing process, and reduce inflammation. This review evaluates the most recent evidence on biomaterials used in rhinology, focusing on these outcomes after ESS. Data Sources MEDLINE, Scopus, Google Scholar, and Clinicaltrials.gov. Review Methods A primary literature search based on the listed databases was performed with combinatorial search terms. Studies were considered for review if they met a set of inclusion and exclusion criteria. Conclusions Some products have performed better than others in clinical trials, although significant heterogeneity among studies does not allow for selection of a clearly superior biomaterial. While nonabsorbable biomaterials are still effective in achieving certain outcomes, newer, absorbable substances may be just as effective and avoid the morbidity associated with nasal packing removal. Steroid-eluting biomaterials have shown promising early results in reducing inflammation and promoting wound healing. Implications for Practice Certain absorbable biomaterials, such as chitosan gel and fibrin glue, have performed well with respect to postoperative hemostasis and wound healing, although they do not address mucosal inflammation. Steroid delivery systems may play an increasingly important role in reducing disease recurrence after ESS, although more studies are needed to assess long-term outcomes.

Complementary and Integrative Treatments: Allergy

Allergic rhinitis (AR) is a global disease affecting hundreds of millions internationally. Substantial pharmacologic gains have been made in the treatment of allergy, including antihistamines, steroids, and leukotriene inhibitors. Pharmacology and immunotherapy are the 2 primary choices in an otolaryngologists armamentarium of allergy treatment. Outside of these options lie complementary and integrative medicine, including various herbs and supplementation along with acupuncture. Some of these methods have shown great efficacy in treating AR and others have failed to show any improvement. This article reviews AR and some of the more common therapies used to care for the disease.

Medical Management of Frontal Sinusitis

Rhinosinusitis is a term that has long been used to describe a diverse disease entity that encompasses several related but distinct conditions involving the paranasal sinuses. Frontal sinusitis represents one such entity with its own unique treatment considerations. Like rhinosinusitis as a whole, the role of medical management in the treatment of frontal sinusitis cannot be overlooked. Contemporary medical management of frontal sinusitis requires recognition of the unique disease process with implementation of targeted therapies aimed at addressing the specific pathophysiology.

Complementary and integrative treatments: upper respiratory infection.

The combination of nasal congestion, rhinorrhea, sore throat, cough, and malaise is the symptomatic profile that constitutes an uncomplicated upper respiratory tract infection (URI), also known as the common cold. Because no known cure exists for a URI, numerous products are available, each marketed with the promise of alleviating the associated symptoms and/or shortening the duration of illness. The evidence supporting these claims is variable and is the focus of this article, with an emphasis on complementary and integrative therapies.

Chronic rhinosinusitis osteoblasts differ in cellular properties from normal bone

Osteitis, characterized by bony thickening and remodeling, is often considered a hallmark of recalcitrant rhinosinusitis. However, there is limited literature examining the bone in chronic rhinosinusitis (CRS) pathology. In this study we cultured osteoblasts from bone harvested during sinus surgery as well as from nondiseased controls to compare their cellular properties.
