Surgery to relieve nasal obstruction: outcome for 366 patients operated on by one senior surgeon.

BACKGROUND: Studies of patient-rated outcome in septoplasty and turbinoplasty most frequently involve several surgeons with varying surgical skills, techniques and experience. The aim of the present study was to evaluate outcome based on one experienced surgeon. METHODS: Three hundred and sixty-six consecutive patients referred for nasal obstruction were included. All the patients were examined with nasal endoscopy before and after decongestion, they filled out a nose VAS and rated their overall general health before and three to six months after surgery. The patients underwent septoplasty, septoplasty plus turbinoplasty or turbinoplasty. RESULTS: The mean nose VAS for nasal obstruction (0-100) preoperatively was 64.7 for all patients. Patients undergoing septoplasty (n = 159) were younger than patients undergoing septoplasty + turbinoplasty (n = 79) or patients undergoing turbinoplasty alone (n = 128). The nose VAS for nasal obstruction improved significantly in all three groups and 25% had a normal nose VAS after surgery in the septoplasty and septoplasty + turbinoplasty groups compared to only 8% in the turbinoplasty alone group. There was no significant difference in the improvement in nasal obstruction between septoplasty and septoplasty + turbinoplasty, but the septoplasty + turbinoplasty group experienced a significantly greater improvement in general health. CONCLUSIONS: In 366 patients operated on by one experienced surgeon, septoplasty and septoplasty + turbinoplasty were more effective at relieving nasal obstruction than turbinoplasty alone. Septoplasty + turbinoplasty resulted in a greater improvement in general health than septoplasty alone, despite the same improvement in nasal obstruction, indicating a beneficial effect of additional turbinoplasty in septoplasty.

Proposal of a CT scoring system of the paranasal sinuses in diagnosing cystic fibrosis.

The purpose of this study was to develop a paranasal sinus CT scoring system that could be used as a diagnostic tool to discriminate cystic fibrosis (CF) patients from control patients examined for sinonasal disease. The model should include as few and easily applicable criteria as possible, supported by statistical analyses and clinical judgement. We used data from 116 CF and 136 control patients. The CF patients were grouped according to the number of confirmed CF mutations: genetically verified (CF-2), or based on sweat testing and clinical findings alone (CF-1, CF-0). Nine paranasal sinus CT criteria, including development, pneumatisation variants and inflammatory patterns, were evaluated. The final model included three criteria: (a) frontal and (b) sphenoid sinus development, and (c) absence of three pneumatisation variants. This model discriminated CF-2 from controls with overlap of summed scores in only 8 of 206 patients. When this model was applied in the CF-1 and CF-0 groups, two populations seemed to exist. A larger group with summed scores overlapping that of the CF-2 group and a smaller group with summed scores overlapping that of the control group. We conclude that this CT scoring system may support, as well as exclude, a CF diagnosis in cases of diagnostic uncertainty.

CT characterization of inflammatory paranasal sinus disease in cystic fibrosis.

PURPOSE: In patients with cystic fibrosis (CF) the prevalence of paranasal sinus affection approaches 100%. We hypothesized that the hyperviscous mucus reducing mucociliary clearance in CF patients could give sinonasal inflammatory patterns different from those in non-CF patients. We wanted to compare the extent and distribution of paranasal sinus disease and the inflammatory patterns in these two groups of patients. MATERIAL AND METHODS: One-hundred-and-eight CF patients (3-54 years old) and 79 controls (7-51 years old) with paranasal sinus disease confirmed at coronal CT were compared. The extent of disease was noted for each sinus and summed for all sinuses. Inflammatory patterns were identified and classified into: 1) routine surgery group (sporadic, infundibular and ostiomeatal complex (OMC) patterns) and 2) complex surgery group (sinonasal polyposis and sphenoethmoid recess (SER) patterns). RESULTS: CF patients had more widespread sinonasal inflammatory changes and more advanced disease for each sinus. Most CF patients displayed sinonasal polyposis and SER patterns while most controls displayed sporadic, infundibular or OMC patterns. As a result, 67% of CF patients were classified to the complex surgery group, compared to only 19% of controls. CONCLUSION: The impaired mucociliary clearance in CF causes widespread inflammatory paranasal sinus disease, with inflammatory patterns more often requiring extensive surgery, with a higher risk of cerebrospinal fluid leak or bleeding, or involving areas that are more difficult to reach with the endoscope.

CT characterization of developmental variations of the paranasal sinuses in cystic fibrosis.

PURPOSE: To describe variations of paranasal sinus development in patients with cystic fibrosis (CF) and in non-CF patients examined for inflammatory sinonasal disease. We focused on anatomic variants that predispose to orbital and cerebral penetration during functional endoscopic sinus surgery (FESS), e.g. hypoplasia of the maxillary sinus and low ethmoid roof. MATERIAL AND METHODS: One hundred and sixteen CF patients (3-54 years, median 18) and 136 control patients (7-51 years, median 31) were examined with coronal CT of the paranasal sinuses. CF patients were grouped according to number of confirmed mutations: CF-2 (n=70), CF-1 (n=32), CF-0 (n=14). CT images were evaluated with respect to paranasal sinus development, pneumatization variants and bony variants. RESULTS: Frontal sinus aplasia and maxillary, ethmoid, and sphenoid sinus hypoplasia were markedly more frequent in CF-2 than in control patients. No CF-2 patient had pneumatization variants such as Haller cells or concha bullosa. Low ethmoid roof was seen in 30% of CF-2 children, but in no control children. CF-1 and CF-0 groups had prevalences of aplasia and hypoplasia intermediate to that of CF-2 and control patients. CONCLUSION: Genetically verified CF patients had less developed sinuses, lacked pneumatization variants, and more often had anatomic variants that predispose to complications during FESS. Normally developed sinuses and pneumatization variants in some genetically unverified CF patients (CF-1, CF-0) suggest that these patients may be erroneously diagnosed.

Complementary role of MR imaging of ethmomaxillary sinus disease depicted at CT in cystic fibrosis.

PURPOSE: To assess whether MR imaging can improve characterization of ethmomaxillary opacification diagnosed at CT in patients with cystic fibrosis (CF) in order to select patients that may benefit from functional endoscopic sinus surgery (FESS). MATERIAL AND METHODS: Sixty-two CF patients (26 females and 36 males) aged 4-50 years (median 20 years) with ethmomaxillary sinus disease at CT underwent MR examination of the paranasal sinuses (coronal T1 and STIR sequences). FESS had been performed in 28 of the patients prior to this study. MR signal intensities were interpreted as mucosal thickening or infectious material, according to a previous study. RESULTS: Three major maxillary sinus MR patterns could be distinguished: Air-filled, oval-shaped pus-filled, and streaky-shaped pus-filled sinus lumen. For air-filled maxillary sinuses with mucosal thickening, CT and MR imaging were diagnostically equivalent. Where CT showed homogeneous opacification of the maxillary sinuses, MR imaging differentiated between thickened mucosa and pus-filled areas. Patients who had undergone FESS most commonly had air-filled or streaky-shaped pus-filled maxillary sinus lumen. In non-operated patients oval-shaped pus-filled sinus lumen was most common and could occur without ethmoid disease. CONCLUSION: MR imaging of the paranasal sinuses can differentiate between infectious material and thickened mucosa and should be used to select CF patients with pus-filled areas that can be eradicated with FESS.

Is homeopathic 'immunotherapy' effective? A double-blind, placebo-controlled trial with the isopathic remedy Betula 30c for patients with birch pollen allergy.

The objective of the study was to examine the effect of the homeopathic remedy Betula 30c vs. placebo for patients with birch pollen allergy. A double-blind, randomized, placebo-controlled trial was carried out. Tablets were given for 4 weeks during the birch pollen season. The setting was Oslo, Norway, May 1995. Patients were aged between 18 and 50 y; 32 patients received Betula 30c tablets and 34 patients received placebo tablets. The main outcome measure was the total score of 17 different allergy symptoms. Daily total scores were calculated, as well as differences and ratios between the run-in and the following time periods. Point estimates of the median difference between the experimental and placebo groups, with their 95% confidence intervals, were the main measure of effect. No statistically significant difference between the groups was found during the first and last period of May. However, from 8 to 18 May, a clinically interesting difference was revealed between the groups, those receiving Betula 30c having fewer and less serious symptoms. For some days these differences were statistically significant. Surprisingly, this group reported more aggravation from the tablets than did the placebo group. With a statistical power of 70% for a defined clinically interesting difference (25%), the present results indicate that treatment with Betula 30c during the pollen season deserves further attention.

CT and MR imaging of the paranasal sinuses in cystic fibrosis. Correlation with microbiological and histopathological results.

PURPOSE: To compare CT and MR findings of the paranasal sinuses in patients with cystic fibrosis (CF) with microbiology and histopathology. Further, to compare microbiology from the maxillary sinuses, nasopharynx and sputum. MATERIAL AND METHODS: CT and MR imaging of the paranasal sinuses were performed in 10 CF patients. Endoscopy and maxillary sinus aspirates were obtained (guided by the MR findings) and analyzed microbiologically and histologically. Samples from the nasopharynx and sputum were analyzed microbiologically. RESULTS: CT and MR were equal in displaying the extent of soft tissue masses, which at CT were homogeneous, while MR showed heterogeneous signals. MR images also demonstrated circumscribed areas with signal void at the STIR sequence with corresponding high to intermediate signal at the T1-weighted sequence. P. aeruginosa was frequently cultured from these areas which we named the "black hole sign". Maxillary sinus cultures revealed the same bacteria as nasopharynx and sputum cultures combined. CONCLUSION: MR images were superior to CT in differentiating soft tissue masses in the paranasal sinuses in CF patients. Bacteria with potential for specialized iron uptake mechanisms were present in areas with signal void at the STIR sequence. Our hypothesis is that the MR "black hole sign" can be explained by paramagnetic properties related to bacterial agents.

Antibiotic treatment of patients with mucosal thickening in the paranasal sinuses, and validation of cut-off points in sinus CT.

We compared the efficacy of penicillin V and amoxycillin treatment with placebo in 70 adult patients from Norwegian family practice with a clinical diagnosis of acute sinusitis and mucosal thickening on CT, but without fluid level or total opacification. The study was randomized and double-blind. Three different outcomes were evaluated; subjective status after 10 days of treatment, difference in clinical score between day 0 and day 10, and duration of the illness episode. Amoxycillin and penicillin V gave no better response to treatment than placebo, evaluated by all three outcome measures. The median duration of the sinusitis episode was 10 days in the amoxycillin- and placebo groups and 13 days in the penicillin-V group. In patients with a clinical diagnosis of acute sinusitis, fluid level and total opacification on CT are good criteria to differentiate between groups of patients that need or do not need antibiotic treatment.

CT findings in general practice patients with suspected acute sinusitis.

PURPOSE: To study CT findings in general practice patients with a clinical diagnosis of acute sinusitis, and to examine the interobserver variation between 2 radiologists with regard to their CT evaluation. MATERIAL AND METHODS: Two hundred and one patients were examined with coronal CT images of the paranasal sinuses within 2 days of the clinical diagnosis. Patients with chronic sinusitis were excluded. Fluid level or total opacification of any sinus were used as evidence of sinusitis. RESULTS: One hundred and twenty-seven (63%) patients had fluid level or total opacification in a sinus region, most in more than one region. One hundred and fifteen had CT signs of sinusitis in the ethmoid region, 84 in the maxillary, 18 in the frontal, and 10 in the sphenoid. Forty-nine patients had a negative Ct. In the evaluation of interobserver agreement, the overall assessment of the CT yielded a kappa value of 0.70. CONCLUSION: The study demonstrated great variation in the CT findings in general practice patients with suspected acute sinusitis. More than one sinus region was affected in most patients in whom sinusitis was confirmed by CT imaging; the most common combination was ethmoid and maxillary sinuses. The interobserver agreement was substantial.

[Parotid gland tumors. What not to do]. / Orespyttkjertelsvulster. Hva man ikke bør gjøre.

Patients with a tumour located anterior or inferior to the ear probably have a parotid gland tumour. These patients should be referred without further investigation to an ear, nose and throat specialist. Diagnostic measures that may be performed are fine needle aspiration cytology and ultrasonography. Biopsy or enucleation of the tumour should not be carried out. Correct treatment is parotidectomy with preservation of the facial nerve. Inadequate primary treatment may lead to a very unpleasant situation for the patient and for the physician. This is illustrated by three case histories.
