Comparison of radical (nasalisation) and functional ethmoidectomy in patients with severe sinonasal polyposis. A retrospective study.

OBJECTIVE: To compare the 5-year outcomes of two endoscopic surgical approaches for diffuse and severe nasal polyposis. STUDY DESIGN: A natural experimental situation gave us the opportunity to compare the results 5 years after radical ethmoidectomy (nasalisation) (n= 39), and functional ethmoidectomy (n= 37). The two surgical procedures were performed by two different surgeons on 76 consecutive patients. There was no random assignment for this retrospective study. METHODS: Five years after surgery, the criteria for comparison were 1) functional results based on a questionnaire using visual analogue scales in patients free of revision surgery; 2) endoscopic and CT-scan assessments of anatomical results. The CT-scans were blinded and randomized, and opacities were measured using a computerized model; 3) the recurrence rate of nasal polyps. RESULTS: Five years after surgery, the overall nasal functional benefit was scored 8.41 +/- 0.40 (mean +/- SEM) after nasalisation, and 5.69 +/- 0.83 after ethmoidectomy P= 0.002) in patients free of revision surgery. The endoscopic appearance of the mucosa was methodically scored according to a pre-defined scale. Results were significantly better in the nasalisation group (6.03 +/- 0.7 versus 3.27 +/- 1.0, P= 0.02). A good correlation was found between the endoscopic and CT-scan scores (r= -0.78, P= 0.0001 for nasalisation, and r= -0.65, P= 0.001 for ethmoidectomy). The total recurrence rate was 22.7% in the nasalisation group, and 58.3% in the ethmoidectomy group (chi2= 10.41, P< 0.01). CONCLUSION: Our study suggests that in the treatment of nasal polyposis complete ethmoidectomy leads to better long term results than incomplete ethmoidectomy.

[Community-acquired acute maxillary sinusitis or rhinosinusitis in adults in France: current management].

Sinus infections, often viral, are a common reason for physician visits. The multiplicity of clinical presentations makes its diagnosis difficult. The problem is to recognize bacterial infection without additional testing, except in cases of treatment failures, complications or relapse. Patients with signs suggestive of rhinosinusitis fall into one of four basic clinical situations: common colds, 'doubtful' rhinosinusitis, apparent acute maxillary bacterial rhinosinusitis, and complications. Anterior rhinoscopy may help confirm diagnosis. Current bacterial epidemiology is based on the results of clinical studies, microbial ecology, and samples taken in cases of treatment failure. The two bacteria isolated most frequently are Streptococcus pneumoniae and Haemophilus influenzae, both of which pose resistance problems. Moraxella catarrhalis, Streptococcus pyogenes and Staphylococcus aureus are isolated less often. The dominant issue in management of acute rhinosinusitis is whether to use antibiotic or symptomatic treatment. For viral infections, antibiotic therapy is useless and highly inadvisable. For 'doubtful' infections, symptomatic treatment is likely to lead to recovery. The use of non-recommended antibiotics also increases the risk of selection of resistant bacteria. When bacterial rhinosinusitis is strongly suspected, recourse to antibiotic treatment is recommended in view of the benefits in this situation (AFSSAPS 2005). This treatment is probabilistic, should be decided at the end of the consultation, and follows the AFSSAPS guidelines.

Prevalence of nasal polyposis in France: a cross-sectional, case-control study.

BACKGROUND: The prevalence of nasal polyposis (NP) has never been established in France due to the lack of diagnostic tools for population-based studies. METHODS: Using a recently validated questionnaire/algorithm (90% specificity and sensitivity) in a population-based random sample, the present cross-sectional, case-control study allowed to determine NP prevalence and describe the principal aspects of NP epidemiology. A total of 10 033 subjects (>/=18 years) were screened. After identification of subjects with NP and those without, another questionnaire was submitted to NP patients only for further data collection. Controls were individuals without NP, matched by gender and age to NP patients. RESULTS: Nasal polyposis prevalence was 2.11% (95% CI 1.83-2.39). NP patients (n = 212, 45% males) were aged 49.4 +/- 17.6 years. No gender preponderance was observed, but NP tended to increase with age. Mean duration of nasal symptoms was 22.4 +/- 15.7 years. Among the 145 patients having already seen a doctor for their symptoms, 77.2% have been referred to a specialist, and 18.6% had a diagnosis of NP. Rhinorrhoea was reported by 39.9% of NP patients, blocked nose by 30.8%, and anosmia by 28.9%. Only 6.9% reported facial discomfort while 24.6% complained about general discomfort. Most NP patients (61.3%) had a pharmacological treatment, a nasal spray for the major part (76.9%). CONCLUSION: The present study provides valuable and reliable information on NP epidemiology in France; the collected information are in accordance with most published international data.

[Treatments of hereditary hemorrhagic telangiectasia of the nasal mucosa].

UNLABELLED: Hereditary Hemorrhagic Telangiectasia is a systemic autosomal dominant disorder involving blood vessels. The most common symptom is recurrent epistaxis. The treatments of these epistaxis are numerous but such treatments are often symptomatic and their effects are often not sustained. Some of these treatments may be complicated by visceral vascular malformations. The aim of this study is to propose a treatment plan for these patients with hierarchical organisation of therapeutic options taking into account of their previous therapy. METHOD: H. Plauchu organized in Paris, december 2002 a meeting with any medical specialists of this disease. They have analysed variety of therapies that have been proposed for epistaxis control in Hereditary Haemorrhagic Télangiectasia. RESULTS: Most common use packing of nasal fossa and then hyperselective embolization of the internal maxillary and facial arteries for severe epistaxis. For chronic epistaxis, best treatment use sclerotics products (Ethibloc) and laser. After discussion, primary embolization could be useful to reduce vascularization of nasal fossa. CONCLUSION: Treatment of epistaxis in Hereditary Haemorrhagic Telangiectasia could increase in few years. Use of an index card of for epistaxis in the disease of Rendu-Osler could help to find treatment of choice.

[Treatment of functional signs of acute maxillary rhinosinusitis in adults. Efficacy and tolerance of administration of oral prednisone for 3 days].

OBJECTIVE: Acute maxillary rhinosinusitis (AMRS) is a pathology in which the pain is often severe and requires appropriate treatment. Although the use of antibiotics is widely documented, the interest of short cycles of corticosteroids in the treatment of the functional manifestations of AMRS is based on professional experience. The aim of this study was to assess the efficacy and tolerance to prednisone administered for 3 days in addition to antibiotherapy in patients presenting with an AMRS. METHOD: This was a double blind, randomised study in parallel groups and controlled versus a placebo, involving patients aged over 18, presenting with an AMRS confirmed by X-ray and endoscopy, having developed less than 5 days and complaining of spontaneous pain assessed as >or=50 millimetres on a visual analog scale (VAS). Together with cefpodoxime, the patients received either prednisone (0.8 to 1.2 mg/kg) for 3 days or a placebo. The primary efficacy endpoint was the mean of the differences versus the baseline value of pain (MPID - mean pain intensity difference) assessed on the VAS from Day 1 to Day 3. The secondary endpoints assessed were the mean of the differences in intensity of nasal obstruction, assessed in the same way as the MPID, the time lapse before the orally expressed relief of the pain (PRID - pain reflief intensity difference) and the administration of paracetamol during the first 3 days. RESULTS: 289 patients (placebo 147, prednisone 142) were assessable for analysis in intent-to-treat (ITT). The global spontaneous pain on inclusion, measured by a VAS was of 73.0 +/- 14.1 mm. The assessments made during the first 3 days of treatment showed a statistically significant difference in favour of the prednisone group regarding MPID: - 4.82 mm (CI 95% -9.25; -0.40) (p=0.03), nasal obstruction - 5.0 mm (CI 95% -9.1; -0.8) (p=0.02) and consumption of paracetamol (p=0.03). There was no difference between the two groups after the end of the antibiotherapy. The tolerance measured throughout the study was comparable between the two groups. CONCLUSION: This study clearly showed the efficacy of a short course of oral prednisone (3 days), versus a placebo, in the treatment of the functional signs of acute maxillary rhinosinusitis with severe pain in adults in addition to an appropriate antibiotic treatment.

[Endoscopic closure of septal perforations by mucosal rotation flaps].

OBJECTIVES: We present a technique of endoscopic endonasal closure of average sized (0.5 - 2 cm) to large (>2 cm) septal perforations. MATERIAL AND METHODS: The surgical technique involves a mucosal rotation flap on a unilateral posterior pedicle without interposition material. We reviewed our experience with eleven patients with average sized and large septal perforations treated over an 8-year period. RESULTS: We based our evaluation on the model proposed by Younger and Blokmanis. Our results were comparable with earlier publications. One-phase closure was achieved in 75% of patients (55% to 90% in the literature reporting all techniques, including external septorhinoplasty and midfacial degloving). CONCLUSION: Our preliminary series provides a basis for a new approach to this condition. The technique is promising for large perforations. This technique could also be considered for other nasal fossae in the event of failed closure. It also offers a way to obtain excellent closure of the anterior portion of the perforation, relieving the patient of the most annoying symptoms. The technique does not contraindicate other procedures which may be performed during the same operation or later.

Surgical anatomy of the turbinal wall of the ethmoidal labyrinth.

The upper part of the lateral nasal wall is formed by a common structure or conchal lamina that is attached all along the junction between the ethmoidal roof and the cribriform plate. From this continuous conchal lamina, the different ethmoidal turbinates take their origin. All these structures form a well defined wall that encloses the ethmoidal cells medially and that deserves the name of "turbinal wall of the ethmoidal labyrinth". The objectives of this paper were: 1) to precisely define the anatomical landmarks of the turbinal wall of the ethmoidal labyrinth, and 2) to study, from an anatomical point of view, the consequences of the surgical resection of the middle turbinate. We performed an anatomic study on 12 frozen human heads, cut in a median-sagittal plane, and then photographed with a millimetre scale in order to perform several measurements. The surface of the turbinal wall of the ethmoidal labyrinth can range from 6.1 to 11.3 cm2. The resection of the middle turbinate preserves approximately half of the turbinal wall, this being around 4.3 cm2 (range 2.6 to 6.3 cm2). The conchal lamina appears as the noble sensorial element of the turbinal wall. It can be described as a continuous bone plate, grossly rectangular in shape, measuring approximately 1 cm in height and 3.5 cm in length that forms the lateral wall of the olfactory groove. The anatomic study shows that its dimensions can vary from simple to double in different individuals. It seems to us that instead of considering the difference of height between the cribriform plate and the ethmoidal roof (Keros classification), we should consider the vertical height of the conchal lamina as a potential risk factor in ethmoidal surgery.

Anosmia following superior turbinate resection.

Nasal polyposis is a chronic inflammatory disease of the sinus mucosa responsible for, among other symptoms, alteration of the sense of smell in a considerable percentage of patients. One of the aims of surgical treatment is the recuperation of the sense of smell, especially in patients with good preoperative indicators suggesting a possible favorable outcome. The purposes of this brief clinical report are to present the case of a patient with nasal polyposis who developed anosmia after a bilateral endoscopic functional ethmoidectomy with inadvertent resection of both superior turbinates, and to discuss briefly the possible physiopathological mechanisms that could explain it.

Evolution of symptoms associated to nasal polyposis following oral steroid treatment and nasalization of the ethmoid--radical ethmoidectomy is functional surgery for NPS.

PURPOSE: The effects on the symptoms of nasal polyposis (NPS) of 1) a 7-day systemic steroid treatment and 2) radical ethmoidectomy (nasalisation) were compared. PATIENTS AND METHODS: Twenty-four patients with NPS whose symptoms failed to respond to medical treatment were included in the study. Symptoms were recorded on Visual Analog Scales (VAS) before (Q1) and the day (Q2) after a 7-day treatment of oral prednisolone (60 mg/day), and a few weeks later the day before surgery (Q3). All patients were operated on bilaterally according to the nasalization principles, i.e. endoscopic radical ethmoidectomy without mucosal preservation, with middle turbinate resection, antrostomy, sphenoidotomy and frontal ostium exposure, and a depot injection of triamcinolone 80 mg the day after surgery. The fourth questionnaire (Q4) was fulfilled one month after surgery, the day of the first postop visit. The following questionnaires were returned by mail at 3 months (Q5), 6 months (Q6), 9 months (Q7), and 12 months (Q8) post-operatively. Patients stayed on topical steroids throughout the study. RESULTS: Nasal obstruction was a major complaint at entry in the study. Following the short-systemic steroid course the obstruction score improved significantly. However, at 2 months after the oral steroid treatment the obstruction score had deteriorated again. Following surgery, obstruction scores ameliorated again and remained stable over the full year of follow-up. Similar results were observed for anterior and posterior rhinorrhea, sneezing and itching. None of the patients reported any intake of systemic steroids during follow-up. CONCLUSION: These data show that 'nasalization' i.e. radical ethmoidectomy with middle turbinate resection and mucosa removal is effective functional surgery for patients with nasal polyposis if medical treatment fails. The subjective effects on the sense of smell are reported in a separate paper published in this issue.

Olfaction in patients with nasal polyposis: effects of systemic steroids and radical ethmoidectomy with middle turbinate resection (nasalization).

AIM: In this prospective study the effect of medical and surgical treatment on subjective olfaction was studied in patients with nasal polyposis (NPS). The effects on nasal obstruction, anterior and posterior rhinorrhea, sneezing and itching are reported in another article in this issue. PATIENTS AND METHODS: Protocol 1. Twenty-four patients with NPS who complained about anosmia were treated with a 7-days course of systemic steroids. Their subjective overall sense of smell was determined with a visual analog scale (VAS) before treatment, immediately after treatment, and two months later. Subsequently all patients underwent surgery bilaterally according to the nasalization principles. The sense of smell was re-evaluated at 1, 3, 6, 9, and 12 months postoperatively. Protocol 2. Thirty-two patients with NPS not responding to medical therapy who, for different reasons, did not receive oral steroid treatment, received surgery only and were followed up during one year after nasalization. Of these patients, 25 were anosmic and 7 normosmic. RESULTS: Protocol 1. Following the 7-day treatment with systemic steroids the olfactory score increased significantly. During the waiting time for surgery (64 +/- 39 days) this score deteriorated again in a significant way. One month after nasalization which included a depot injection of triamcinolone 80 mg the day after surgery, the olfactory score ameliorated again and remained stable at 3, 6, 9, and 12 months. None of the patients reported any intake of systemic steroids during the one-year of follow-up. Statistically, there was a trend suggesting that the 12 month post-nasalization score was better than the immediate post-oral steroid score. A good correlation between the improvement of the sense of smell after 7 days of systemic steroids and one year after nasalization was found. Protocol 2 One month after the nasalization protocol, olfaction in patients of the hypo-anosmic group had improved considerably. Scores at 3, 6, 9, and 12 remained very stable. The sense of smell in the normosmic group did not change after surgery and remained stable during the year of follow-up. In total, 49 patients with a severe loss of smell showed a significant improvement at 12 months after surgery. CONCLUSION: The present study shows that 1) long-lasting correction of olfactory dysfunction produced by nasal polyposis can be achieved through the combination of nasalization and low dose of nasal steroids, 2) middle turbinate resection does not alter the possibilities to restore the sense of smell.

[ENT inflammation and importance of fenspiride].

PERSISTENT INFLAMMATION: Inflammation may persist despite the eviction of the aggressive agent because of the disruption of the regulator mechanisms. In such patients, drugs such as fenspiride can be effective at several levels, from onset of inflammation, in an attempt to control its progression. INHIBITION OF NEUROPHIL MIGRATION: Could be a very interesting propriety for controlling inflammation of the human respiratory mucosa. CONTROL OF FREE RADICALS: In certain cases, clearance of free oxygen radicals by cells implicated in the inflammatory process may be overrun. Fenespiride can limit the production of free radicals, probably at the level of the producing cells. ACTION ON THE ARACHIDONIC ACID CASCADE: The mechanism and site of action of fenspiride remains to be clarified. It does not act like conventional antiinflammatory drugs by inhibiting cyclo-oxygenase. ANTIHISTAMINE ACTIVITY: Fenspiride has a certain antihistamine activity, basically by blocking H1 receptors. This action should be tested in subjects with nonspecific nasal hyperreactivity. OTHER PROPERTIES: Fenspiride also has an alpha-1-adrenolytic activity and an inhibitor effect on cyclic AMP, two properties which could have an impact on inflammatory diseases of the upper airways.

Clinical factors influencing the eosinophil infiltration of nasal polyps.

AIMS AND METHODS: Our study, based on a retrospective chart analysis, was aimed 1) to describe the varying degree of eosinophil infiltration in a series of 263 adult patients operated on diffuse and bilateral nasal polyposis (NPS) after failure of medical treatment, in 15 cystic fibrosis patients with bilateral nasal polyps, and in 31 patients with chronic sinusitis without polyps (18 bilateral, 13 unilateral) 2) to search for clinical factors that might influence the degree of eosinophil infiltration. Eosinophil infiltration was expressed semi-quantativity as a percentage of inflammatory cells. RESULTS: Our study confirms that eosinophil infiltration is a striking feature of nasal polyposis. All patients with chronic sinusitis showed less than 10% eosinophils (mean +/- SEM = 2 +/- 2%) whereas 88% of patients with NPS showed more than 10% eosinophils (50 +/- 2%). Cystic fibrosis lied in between with 40% of patients showing more than 10% eosinophils. In idiopathic bilateral NPS the number of eosinophils was increased in patients with asthma (58 +/- 3%) and even more in Widal's triad (75 +/- 4%). Atopic patients did not have more eosinophils (52 +/- 5%). Patients treated with systemic steroids within two months before surgery showed decreased eosinophil infiltration (22 +/- 3% vs 50 +/- 2 for treated versus untreated) whereas patients treated with topical steroids did not (47 +/- 2%). CONCLUSIONS: Thus, a link might exist between clinical presentation and eosinophil infiltration. Chronic sinusitis and nasal polyps are probably not the same disease. Eosinophils appear as a link between nasal polyps, asthma and aspirin intolerance. Atopic status does not modify eosinophil infiltration of nasal polyps. Systemic steroids appear significantly more effective to reduce the eosinophil infiltrate than topical steroids in our selected group of operated patients.
