Roth MD Abstract Background. Primary sinonasal malignant melanoma (SNMM) is a rare clinical entity. There is neither a classification nor a staging system nor an evidence-based treatment concept established. Our objective was to find potential risk factors predicting the outcome. Methods. Twenty-five patients with histologically confirmed SNMM were consecutively included and retrospectively analyzed. Staging methods were nasal endoscopy, CT, MRI, and positron emission tomography (PET) scan. Patients were selected for a curative or palliative concept. All patients had postoperative follow-up with control-MRI at 3 and 6 months. Restaging was performed when local recurrence occurred. Results. Nineteen patients underwent primary surgery with curative intention; in 16 cases with tumor free margins. Thirteen patients (68%) had transnasal endoscopic surgery, 4 lateral rhinotomy, and 2 transfacial approach with orbital exenteration. Six patients (32%) had palliative therapy and 7 patients (37%) had adjuvant radiotherapy. Despite radical operations, 6 patients (37%) showed local recurrence and 8 patients (50%) developed distant metastasis. In 2 patients with incomplete surgery, regional metastasis was noted. The median disease-free interval was 18 months, and the median overall survival rate was 23 months. Conclusion. SNMMs of the ethmoid and maxillary sinuses have a worse prognosis than other localizations in the nasal cavity; infiltration into the skull base, orbit, or facial soft tissue correlates with a very poor outcome corresponding to the palliative situations. Furthermore, local recurrence insinuates aggressive disease with short survival rate. A main difference from its cutaneous counterpart seems to be a primary tendency to hematogenic spread. Further research is needed to confirm these findings. © 2010 Wiley Periodicals, Inc. Head Neck, 2010 [source] United airways again: high prevalence of rhinosinusitis and nasal polyps in bronchiectasisALLERGY, Issue 5 2009J. M. Guilemany Background:, Although various relationships between the lower and upper airways have been found, the association of bronchiectasis with chronic rhinosinusitis and nasal polyps has not been thoroughly evaluated. This study was undertaken to examine the association of idiopathic and postinfective bronchiectasis with chronic rhinosinusitis and nasal polyposis. Methods:, In a prospective study, 56 patients with idiopathic and 32 with postinfective bronchiectasis were evaluated for chronic rhinosinusitis and nasal polyposis by using EP3OS criteria and assessing: symptoms score, nasal endoscopy, sinonasal and chest CT scan, nasal and lung function and nasal and exhaled NO. Results:, Most bronchiectasis patients (77%) satisfied the EP3OS criteria for chronic rhinosinusitis, with anterior (98.5%) and posterior (91%) rhinorrhea and nasal congestion (90%) being the major symptoms. Patients presented maxillary, ethmoidal and ostiomeatal complex occupancy with a total CT score of 8.4 ± 0.4 (0,24). Using endoscopy, nasal polyps with a moderate score of 1.6 ± 0.1 (0,3) were found in 25% of patients. Nasal NO was significantly lower in patients with nasal polyposis (347 ± 62 ppb) than in those without them (683 ± 76 ppb; P < 0.001), and inversely correlated (R = ,0.36; P < 0.01) with the ostiomeatal complex occupancy. In the chest CT scan, patients with chronic rhinosinusitis showed a higher bronchiectasis severity score (7.2 ± 0.5; P < 0.001) than patients without (3.7 ± 0.7). The prevalence of chronic rhinosinusitis, nasal polyps and other outcomes were similar in idiopathic and postinfective bronchiectasis. Conclusions:, The frequent association of chronic rhinosinusitis and nasal polyposis with idiopathic and postinfective BQ supports the united airways concept, and it suggests that the two type of bronchiectasis share common etiopathogenic mechanisms. [source] Important research questions in allergy and related diseases: 3-chronic rhinosinusitis and nasal polyposis , a GA2LEN studyALLERGY, Issue 4 2009C. Bachert Chronic rhinosinusitis is one of the most common health care challenges, with significant direct medical costs and severe impact on lower airway disease and general health outcomes. The diagnosis of chronic rhinosinusitis (CRS) currently is based on clinical signs, nasal endoscopy and CT scanning, and therapeutic recommendations are focussing on 2 classes of drugs, corticosteroids and antibiotics. A better understanding of the pathogenesis and the factors amplifying mucosal inflammation therefore seems to be crucial for the development of new diagnostic and therapeutic tools. In an effort to extend knowledge in this area, the WP 2.7.2 of the GA2LEN network of excellence currently collects data and samples of 1000 CRS patients and 250 control subjects. The main objective of this project is to characterize patients with upper airway disease on the basis of clinical parameters, infectious agents, inflammatory mechanisms and remodeling processes. This collaborative research will result in better knowledge on patient phenotypes, pathomechanisms, and subtypes in chronic rhinosinusitis. This review summarizes the state of the art on chronic rhinosinusitis and nasal polyposis in different aspects of the disease. It defines potential gaps in the current research, and points to future research perspectives and targets. [source] Chronic rhinosinusitis and nasal polyps: the role of generic and specific questionnaires on assessing its impact on patient's quality of lifeALLERGY, Issue 10 2008I. Alobid Chronic rhinosinusitis (CRS) including nasal polyps is a chronic inflammatory disease of the nasal and paranasal sinus mucosa that, despite differing hypotheses of its cause, remains poorly understood. Primary symptoms are nasal blockage, loss of smell, rhinorrhea, and facial pain or pressure. Chronic rhinosinusitis causes significant physical symptoms, has a negative impact on quality of life (QoL), and can substantially impair daily functioning. A global evaluation of patients must include, together with nasal symptoms, nasal endoscopy, and CT scan, the measurement of QoL. To assess QoL in CRS, specific and generic questionnaires may be used. Chronic rhinosinusitis has a considerable impact on a patient's QoL but comorbidities, such as asthma and atopy, have an accumulative negative effect. Both medical and surgical treatments lead to a similar improvement on the QoL of CRS and nasal polyp patients. [source] Relationship Between Rhinitis Duration and Response to Nasal Decongestion Test,THE LARYNGOSCOPE, Issue 7 2008Giorgio Ciprandi MD Abstract Objectives/Hypothesis: Nasal obstruction depends on allergic inflammation. Decongestion tests evaluate the reversibility of nasal airflow limitation. It has been previously reported that duration of persistent allergic rhinitis (PER) may involve important functional consequences. The purpose of the study was to evaluate the impact of the duration of rhinitis on the response to nasal decongestion test in a cohort of patients with PER. Methods: A total of 312 patients with moderate-severe PER were prospectively and consecutively evaluated: 234 males and 78 females, mean age 23.6 years. A detailed clinical history was taken and complete physical examination, nasal endoscopy, skin prick test, rhinomanometry, and nasal decongestion test were performed for all patients. Results: A strong inverse correlation was observed (Pearson's r = ,0.81) between rhinitis duration (years) and posttest percentage change of nasal airflow values. Conclusions: The duration of PER may induce a progressive impairment of the response to nasal decongestion test. [source] Nasolacrimal Duct Orifice Cysts in Adults: A Previously Unrecognized, Easily Treatable Cause of EpiphoraTHE LARYNGOSCOPE, Issue 10 2007John M. DelGaudio MD Abstract Background: Epiphora is a common problem evaluated by ophthalmologists and otolaryngologists. It is typically the result of obstruction at some level of the nasolacrimal system, either the canaliculi, sac, or duct. Multiple etiologies exist, including scarring from infection or trauma, tumors, or masses. Cysts of the nasolacrimal duct orifice (dacryocystoceles) in the inferior meatus have been described in neonates, usually presenting as obstructive nasal masses shortly after birth. Nasolacrimal duct orifice cysts have not been described in the adult population in the medical literature. Patients: Three patients were identified with epiphora as a result of cysts in the inferior meatus at the opening of the nasolacrimal duct. All patients presented with constant epiphora and were referred for dacryocystorhinostomy by an ophthalmologist or an otolaryngologist. None of the patients had a previous history of nasolacrimal duct (NLD) surgery. One patient had previous endoscopic sinus surgery for nasal polyps. Cysts were identified by nasal endoscopy of the inferior meatus in all patients. Results: All patients underwent endoscopic resection of the inferior meatus cyst to relieve the obstruction of the NLD. Two procedures were performed under general anesthesia and one under intravenous sedation. All patients had complete relief of epiphora and have had no evidence of recurrence of the symptoms or the cyst in 4 to 10 months follow-up. Conclusions: NLD orifice cysts are easily correctable causes of epiphora. Routine inferior meatus endoscopy should be routinely performed in patients with epiphora to identify whether on not this pathology is present prior to performing dacryocystorhinostomy. [source] Long-Term Results after Endoscopic Sinus Surgery Involving Frontal Recess DissectionTHE LARYNGOSCOPE, Issue 4 2006Michael Friedman MD Abstract Objective: To assess long-term follow-up on a cohort of patients who underwent endoscopic frontal sinus surgery with identification and preservation of the natural frontal outflow tract. Study Design and Settings: Retrospective chart review, telephone interview, and endoscopic evaluation on a previously studied cohort of patients at a university affiliated medical center. Results: Two hundred patients who underwent endoscopic frontal sinus surgery were previously studied and reported after short-term (mean = 12.2 mo) follow-up. One hundred fifty-two (76%) patients were available for long-term (mean 72.3 mo) follow-up and assessment of subjective symptoms. Fifty-seven of 152 (37.5%) patients also had nasal endoscopy for evaluation of objective findings. The percentage of patients responding to telephone interview reporting overall improvement after surgery was 92.4%. Endoscopic assessment revealed patency of the frontal sinus in 67.6% of the patients after initial surgery. Thirteen additional patients had patent sinuses after revision procedures, bringing overall patency rate to 71.1%. We found statistically significant correlation of asthma and smoking and poor subjective and objective outcome. Conclusion: Long-term assessment of subjective and objective findings in our previously reported cohort of patients who underwent frontal sinus surgery indicates that the frontal sinus, similar to any other sinus, can be successfully treated surgically by preserving the natural frontal sinus outflow tract. [source] The Evolution of Surgery on the Maxillary Sinus for Chronic Rhinosinusitis,THE LARYNGOSCOPE, Issue 3 2002FRCS(Ed), Valerie Lund FRCS Objective To examine the management of the maxillary sinus in chronic rhinosinusitis over the last 500 years. Method A literature review was conducted. Result The maxillary sinus was first recognized in the 16th century and its role as a source of infection became the focus of attention, beginning with Nathaniel Highmore in 1651 and continuing up until the 21st century. The surgical drainage of the sinus was achieved by a variety of routes, including the alveolar margin, anterior wall, and middle and inferior meati. The rationale for these procedures, developed in a pre-antibiotic era, may be re-examined in the context of our present understanding of the pathophysiology of chronic rhinosinusitis. Conclusion The maxillary sinus has been the focus of surgical attention from the 17th century onward largely as a result of its size and accessibility, initially reinforced by plain x-ray. However, in the 20th century, the advent of computed tomography and nasal endoscopy has reaffirmed the relationship of the maxillary sinus to the ostiomeatal complex in chronic rhinosinusitis, as originally demonstrated by pioneers such as Zuckerkandl, and redirected the focus of our therapeutic approaches. [source] The Diagnosis of a Conductive Olfactory Loss,THE LARYNGOSCOPE, Issue 1 2001Allen M. Seiden MD, FACS Abstract Objectives/Hypothesis Two of the most common causes of olfactory loss include upper respiratory infection (URI) and nasal or sinus disease. The etiology of most URI-related losses is thought to be viral and, as yet, there is no available treatment. In contrast, nasal or sinus disease produces an obstructive or conductive loss that often responds dramatically to appropriate therapy. Therefore, the distinction is important but in many cases may be difficult because such patients often present with no other nasal symptoms, and routine physical findings may be nonspecific. The purpose of this report is to characterize those aspects of the history and physical examination that will help to substantiate the diagnosis of a conductive olfactory loss. Study Design A retrospective, nonrandomized study of consecutive patients presenting with a primary complaint of olfactory loss. Methods This study reviewed 428 patients seen at a university-based taste and smell clinic from July 1987 through December 1998. Of this total, 60 patients were determined to have a conductive olfactory loss. All patients were referred specifically because of a primary chemosensory complaint. The University of Pennsylvania Smell Identification Test (UPSIT; Sensonics, Inc., Haddon Heights, NJ) was administered in all cases. Results The most commonly diagnosed etiologies of olfactory loss were head injury (18%), upper respiratory infection (18%), and nasal or sinus disease (14%). Of the 60 patients with a conductive loss, only 30% complained of nasal obstruction, whereas 58% described a history of chronic sinusitis. Only 45% reported that their olfactory loss at times seemed to fluctuate in severity. Anterior rhinoscopy failed to diagnose pathology in 51% of cases, whereas nasal endoscopy missed the diagnosis in 9%. Systemic steroids elicited a temporary reversal of conductive olfactory loss in 83% of patients who received them, offering a useful diagnostic maneuver, whereas topical steroids did so in only 25%. Conclusions The etiology for olfactory loss can in many cases be difficult to determine, but it is important to establish prognosis and to predict response to therapy. Diagnosis requires a thorough history, appropriate chemosensory testing, and a physical examination that should include nasal endoscopy. A trial of systemic steroids may serve to verify that the loss is indeed conductive. [source] Evaluating budesonide efficacy in nasal polyposis and predicting the resistance to treatmentCLINICAL & EXPERIMENTAL ALLERGY, Issue 1 2009F. C. P. Valera Summary Background Cell resistance to glucocorticoids is a major problem in the treatment of nasal polyposis (NP). Objectives The objectives of this study were to observe the effect of budesonide on the expression of IL-1,, TNF-,, granulocyte macrophage-colony stimulating factor, intercellular adhesion molecule (ICAM)-1, basic fibroblast growth factor, eotaxin-2, glucocorticoid receptor (GR)-,, GR-,, c-Fos and p65 in nasal polyps and to correlate their expression to clinical response. Methods Biopsies from nasal polyps were obtained from 20 patients before and after treatment with topical budesonide. Clinical response to treatment was monitored by a questionnaire and nasal endoscopy. The mRNA levels of the studied genes were measured by real-time quantitative (RQ)-PCR. Results There was a significant decrease in the expression of TNF-, (P<0.05), eotaxin-2 (P<0.05) and p65 (P<0.05) in NP after treatment. Poor responders to glucocorticoids showed higher expression of IL-1, (3.74 vs. 0.14; P<0.005), ICAM-1 (1.91 vs. 0.29; P<0.05) and p65 (0.70 vs. 0.16; P<0.05) before treatment. Following treatment, IL-1, (4.18 vs. 0.42; P<0.005) and GR-, (0.95 vs. 0.28; P<0.05) mRNA expression was higher in this group. Conclusion Topical budesonide reduced the expression of TNF-,, eotaxin-2 and p65. Poor responders to topical budesonide exhibit higher levels of IL-1,, ICAM-1 and nuclear factor (NF)-,B at diagnosis and higher expression of both IL-1, and GR-, after treatment. These results emphasize the anti-inflammatory action of topical budesonide at the molecular level and its importance in the treatment of NP. Nevertheless, IL-1,, ICAM-1 and NF-,B may be associated with primary resistance to glucocorticoids in NP, whereas higher expression of GR-, in poor responders only after glucocorticoid treatment may represent a secondary drug resistance mechanism in this disease.
