SNOT-22 scores after 6 months of aspirin therapy are predictive of long-term quality of life in AERD.

Background: Aspirin exacerbated respiratory disease (AERD) is an inflammatory condition that consists of eosinophilic asthma, chronic rhinosinusitis with nasal polyps, and respiratory reactions to cyclooxygenase-1 inhibitors. Aspirin therapy after aspirin desensitization (ATAD) is the most extensively studied treatment paradigm for AERD. Objective: The objective was to identify which time point of ATAD was most predictive of long-term outcomes as measured by the 22-item Sino-Nasal Outcome Test (SNOT-22). Methods: A retrospective chart review was conducted of patients at a single institution who underwent endoscopic sinus surgery, followed by ATAD, and had remained on ATAD for 2 consecutive years. SNOT-22 scores were recorded at predesensitization as well as at the 3-, 6-, 12-, and 24-month postdesensitization time points. The patients were separated into two cohorts at each of the data collection time points based on whether their SNOT-22 scores were < 20 (responders) or ≥ 20 (nonresponders). Responder status was compared between each time point and at 24-month postdesensitization. The odds ratios (OR) were then calculated between the two groups at each of the following time points: postsurgery/predesensitization, and 3-, 6-, and 12-month postdesensitization. Results: There were 70 patients who met the inclusion criteria of having 24-month postdesensitization SNOT-22 scores available. Responder status at 6 months after surgery had the most predictive OR 16.5 (95% confidence interval, 3.71-73.44) for long-term outcomes at 24 months. Conclusion: The SNOT-22 scores after 6 months of ATAD showed the greatest predictive value for long-term quality-of-life outcomes and, therefore, poor 6-month SNOT-22 scores could serve as a basis for consideration of alternative therapies.

Usefulness of bilateral mucoplasty plus reboot surgery in severe type-2 chronic rhinosinusitis with nasal polyps.

BACKGROUND: Although extended endoscopic sinus surgery (ESS) constitutes an alternative approach in patients with Chronic Rhinosinusitis with Nasal Polyps (CRSwNP), the surgical techniques proposed so far do not allow for an optimal control of the disease. This study introduces bilateral mucoplasty as a complementary technique to extended ESS such as reboot surgery, analyzing its benefits in healing and quality of life (QoL). METHODS: Patients diagnosed with severe Type-2 CRSwNP were selected for a prospective cohort study in two surgery groups: reboot surgery plus bilateral mucoplasty versus reboot surgery only. In the first group, an autologous endonasal mucosal graft from the nostril floor was placed bilaterally onto the ethmoidal roof. Endoscopic, radiological and QoL outcomes were compared before and one year after surgery between the two groups using Modified Lund Kennedy (LKM), Meltzer and Lund Mackay (LM) scores, and the Sino-Nasal Outcome Test 22 (SNOT-22). RESULTS: 64 patients with homogeneous baseline characteristics were included: 17 patients underwent a reboot surgery plus a bilateral mucoplasty and 47 a reboot surgery only. LKM, Meltzer and SNOT-22 scores showed significant differences before and after surgery in both groups, with higher improvement in the mucoplasty group. A greater mean improvement of 20.5 ± 6.4 points in SNOT-22 change was associated with bilateral mucoplasty. CONCLUSION: Bilateral mucoplasty plus reboot surgery constitutes a useful surgical resource in Type-2 CRSwNP patients, showing improved endoscopic, radiological and QoL outcomes one year after surgery. Further studies are needed to determine their long-term benefits.

Open, prospective, multicenter study on postoperative intranasal phototherapy in nasal polyposis.

BACKGROUND: The therapeutic effect of ultraviolet (UV) light is generally attributed to its immunosuppressive and immunomodulatory effects. Since chronic inflammation is the major factor in the development of nasal polyposis, we have previously used mixed ultraviolet-visible light (mUV-VIS, Rhinolight®) phototherapy for the treatment of nasal polyps. AIMS: In the present open, multicenter study, our aim was to delineate whether mUV-VIS applied postoperatively in vivo together with intranasal steroid treatment could reduce the recurrence of nasal polyps. METHODS: After functional endoscopic sinus surgery, one group of patients received mUV-VIS light together with standard intranasal steroid (mometason furoate 2 × 200 µg) application for a 12-week treatment period, whereas the other patient group obtained only intranasal steroid for the same duration. We recorded nasal endoscopy images and obtained demographical and clinical data, total nasal score (TNS), and nasal obstruction symptom evaluation (NOSE). We performed acoustic rhinometry and measured nasal inspiratory peak flow. Follow-up was 12 months. RESULTS: We found that the recurrence of nasal polyps was significantly diminished, and based on video-endoscopic measurements, the size and grade of recurrent polyps were significantly smaller in the phototherapy-receiving group. Nasal obstruction values and NOSE were significantly better throughout the follow-up period in the mUV-VIS light-treated group than in the intranasal steroid monotreatment group. CONCLUSIONS: Rhinophototherapy together with standard nasal steroid application may have a supportive role in the treatment of recurrent bilateral nasal polyps.

Benefits of biologic therapy administered for asthma on co-existent chronic rhinosinusitis: A real-world study.

BACKGROUND: Asthma and some chronic rhinosinusitis (CRS) subtypes are mediated by similar pathophysiologic mechanisms. The purpose of this study was to evaluate the effects of biologic therapy for asthma on co-existent CRS in the "real-world" setting. METHODS: A review of electronic health records (2016-2019) at Mayo Clinic was conducted to identify asthma patients treated with biologics who had co-existent CRS. Matched-pair analyses compared pretherapy and posttherapy Lund-Mackay computed tomography (CT) scores and 22-item Sino-Nasal Outcome Test (SNOT-22) scores. Performance of endoscopic sinus surgery (ESS) after initiating biologics was studied. RESULTS: We identified 247 patients who received anti-asthma biologic therapy and had co-existent CRS. Of these, 181 patients (73.3%) had CRS with nasal polyposis (CRSwNP) and 66 (26.7%) had CRS without nasal polyposis (CRSsNP). The biologics utilized were omalizumab (51.0%), mepolizumab (46.6%), benralizumab (10.5%), reslizumab (1.6%), and dupilumab (2.4%). Anti-interleukin-5 (anti-IL-5) intervention was associated with significant improvement in CT scores (CRS overall, CRSwNP subgroup, CRSsNP subgroup) and SNOT-22 scores (CRS overall, CRSwNP subgroup). Patients on omalizumab had a decrease in CT scores, but not SNOT-22 scores. ESS was performed in 206 patients (84.1%); 55 (22.3%) underwent surgery post-biologic intervention (anti-IL-5: 16.5%; omalizumab 27.8% of patients). CONCLUSION: Anti-IL-5 agents were associated with improved CT and SNOT-22 scores in the overall CRS group and in CRSwNP subgroup; CRSsNP patients showed improved CT scores only. Omalizumab improved CT but not SNOT-22 scores. ESS was performed in 22% of patients after initiating biologics. These real-world results may influence future trial designs and clinical applications of biologics for CRS. ©2021 ARSAAOA, LLC.

Latest developments on topical therapies in chronic rhinosinusitis.

PURPOSE OF REVIEW: Topical therapies play an important role in the management of chronic rhinosinusitis (CRS). A detailed literature review was undertaken to appraise recent evidence surrounding current topical therapies and novel treatments used in the setting of recalcitrant CRS. RECENT FINDINGS: Effective sinus surgery aids in the delivery of topical therapies. Budesonide nasal rinses delivered by saline irrigation offer clinical and symptomatic improvements pre and postoperatively with a well-proven safety profile. Topical steroids may additionally offer direct antibacterial effects as per in-vitro testing. Topical antibiotics are not recommended in routine practice; however, they may be of benefit for short-term eradication therapy. Novel treatments are under keen investigation and include bacteriophage, colloidal silver and manuka honey. The evidence base for these treatments is not robust enough to recommend their routine use at present. SUMMARY: Topical steroids delivered in conjunction with saline nasal irrigation offer the best combination of treatments in CRS and should be considered a standard of care. Wide surgical access and aggressive surgical debridement of polyposis facilitates the delivery of steroid irrigations to sinonasal mucosa and is associated with improved long-term outcomes following endoscopic sinus surgery. The use of novel treatments remains within the research setting alone.

Role of Amphotericin B in Nasal Irrigation for Chronic Rhinosinusitis with Nasal Polyps.

OBJECTIVE: To determine the effect of topical antifungal irrigation fluid containing amphotericin B on nasal polyp and their recurrence pattern, and to study the association of serum IgE in predicting the presence of fungus along with the nasal polyps. STUDY DESIGN: An interventional study. PLACE AND DURATION OF STUDY: Dow University Hospital, Dow International Medical College, DUHS, Karachi, from June 2015 to June 2017. METHODOLOGY: All adult patients having nasal polyps, who had not undergone any previous nasal surgery, were included in the study. Patients aged under 18 years, history of granulomatous diseases, immunosuppression, invasive fungal sinusitis, and pregnant ladies were excluded from the study. The ratio was kept as 1:2; one receiving irrigation with amphotericin B and the other only saline nasal irrigation without the medicine. After surgery, the patients were divided into two groups; 58 patients were in the placebo group and 29 in the amphotericin group. Serum IgE levels were documented before and one month postoperative treatment. Serum IgE level of more than 250 ng/ml was taken as a high value. All the patients were followed for six months. Recurrence was defined as the recurrence of nasal symptoms and recurrence of mucosal thickening based on repeat CT scan. Frequency tables and cross tabulations using Chi-square test were performed with p-values of 0.05 taken as significant were performed on different variables. RESULTS: A total of 87 patients were inducted. Overall 22 (25.3%) patients had recurrence of symptoms at six-month followup visit. Twelve (13.7%) of these were in the placebo group and 10 (11.5%) were in the amphotericin B nasal irrigation group. Serum IgE level preoperatively ranged between 52 - 9344 ng/dl; postoperatively it ranged from 13-1050 ng/dl. When pre and postoperative serum IgE level were compared with each other and CT scan scores, using Chi-square test, the difference was significant (p<0.001). CONCLUSION: Amphotericin B improved the CT scan score of the patients. The nasal irrigation of amphotericin B did not show significant change in the recurrence pattern of chronic sinuses with polyps. Serum IgE can be used as marker for the presence and response to treatment for non-invasive fungal sinusitis.

Impact of saline irrigation and topical corticosteroids on the postsurgical sinonasal microbiota.

BACKGROUND: Topical treatments with nasal saline irrigation, topical steroid sprays, or corticosteroid rinses can improve sinonasal symptoms in chronic rhinosinusitis (CRS). However, the impact of these therapies on commensals (Corynebacterium) and on biofilm pathogens associated with CRS (Staphylococcus aureus and Pseudomonas) is not well characterized. METHODS: Paired nasal and sinus swabs were collected endoscopically from 28 controls and 14 CRS patients with nasal polyposis (CRSwNP) who had not received systemic antibiotics or corticosteroids in the previous 8 weeks. Total DNA from swab eluents were extracted and analyzed by 16S rRNA gene-based pyrosequencing. A total of 359,077 reads were obtained and classified taxonomically. The association of use of topical therapies with sinonasal microbiota composition was assessed by factor/vector-fitting. The proportional abundances of sinonasal bacteria between topical therapy users and nonusers were further compared by 2-tailed Kolmogorov-Smirnov test among controls and among CRSwNP participants. RESULTS: Nasal saline irrigation, with or without added budesonide, was not associated with significantly distinct sinonasal microbiota composition or significantly decreased Pseudomonas or S. aureus abundances among either controls or CRSwNP participants. Corynebacterium was slightly lower in controls that reported using saline irrigation than those who did not. No significant association was found between nasal saline irrigation and the proportional abundances of Pseudomonas, S. aureus, and Corynebacterium in CRSwNP participants. However, male CRSwNP patients were noted to have significantly higher Corynebacterium proportional abundances than their female counterparts. The use of topical steroid sprays was associated with a distinct microbiota in control subjects, characterized by higher proportional abundances of Dolosigranulum and Simonsiella and a lower proportional abundance of Campylobacter. CONCLUSION: Nasal saline irrigation is not associated with a distinct alteration in the proportional abundance of commensal bacteria or biofilm-forming pathogens in CRSwNP patients. However, use of topical intranasal corticosteroid sprays in control subjects is associated with a distinct sinonasal microbiota.

Hemostatic effect of hot saline irrigation during functional endoscopic sinus surgery: a randomized controlled trial.

BACKGROUND: The endoscopically magnified operative field in functional endoscopic sinus surgery (FESS) makes even a small amount of bleeding a potentially significant hindrance. It is thought that irrigation with hot saline during surgery may improve surgical field of view by producing a hemostatic effect. Our objective was to assess the effectiveness of hot saline irrigation (HSI) compared to room temperature saline irrigation (RTSI) in the control of intraoperative bleeding during FESS. METHODS: Sixty-two chronic rhinosinusitis (CRS) patients undergoing FESS were randomized to 2 treatment arms in an equal ratio. Subjects received either HSI (49°C) or RTSI (18°C), 20 mL every 10 minutes, for the duration of FESS. The Boezaart endoscopic field of view grading system was the primary outcome measure. Boezaart score, heart rate, and mean arterial blood pressure (MABP) were recorded at 10-minute intervals between irrigations. RESULTS: Mean endoscopic surgical field of view (Boezaart score) did not significantly differ between the HSI and RTSI groups (1.5 ± 0.6 vs 1.3 ± 0.5; p = 0.23). However, when FESS was longer than 2 hours in duration, the Boezaart scores were significantly better in the HSI group (1.6 ± 0.6 vs 1.2 ± 0.4; p = 0.04). We found that blood loss per minute was significantly reduced (p = 0.02) in all cases in which HSI was used (2.3 ± 1.0) compared to RTSI (1.7 ± 1.1). Despite this, heart rate (p = 0.32) and MABP (p = 0.14) did not significantly differ between treatment groups. CONCLUSION: HSI may be beneficial in improving surgical field of view in FESS after 2 hours of operating time. A significant reduction in rate of blood loss may be attained with HSI.

Effect of greater palatine canal injection on estimated blood loss during endoscopic sinus surgery.

PURPOSE: We compare estimated blood loss (EBL) during endoscopic sinus surgery (ESS) between patients receiving transoral greater palatine canal (GPC) and transnasal infiltration (combined group) to patients receiving only transnasal infiltration (control group). CT stage, endoscopic stage, revision surgery, presence of polyps, degree of resident involvement, and operative time (OT) are also evaluated. METHODS: Injection with 1% lidocaine with 1:100,000 epinephrine was performed through the GPC and transnasally in the "combined" study group (20 patients) and only transnasally in the control group (22 patients). Charts, operative reports, and CT scans were reviewed and demographic data as well as pertinent information collected. Data analysis was performed using SPSS Version 16 (SPSS Inc., Chicago, Illinois). RESULTS: Twelve females and 8 males underwent combined injections and 16 males and 6 females received transnasal injections only. Average ratio of EBL to OT was 2.9 mL/min for the combined group and 4.1 mL/min for the control group (p=0.05). Presence of polyps and revision surgery lead to a statistically significantly higher EBL (p<0.05). Increased EBL and OT were noted with higher endoscopic and CT stages. No complications were reported. CONCLUSIONS: Increased endoscopic and CT stages, presence of polyps, and revision surgery may all lead to greater EBL in ESS. Although there was a trend towards decreased EBL in the combined group, this however did not reach statistical significance. Combined injection through the GPC and nasal cavity appears to be a safe method to decrease EBL during ESS.

Impact of mitomycin C on the mRNA expression signatures of immunological biomarkers in eosinophilic nasal polyposis.

BACKGROUND: The topical application of mitomycin C has been evaluated as a complementary therapy for eosinophilic nasal polyposis (ENP). However, the mechanism underlying the additional benefits of mitomycin C for the control of eosinophilic inflammation and prevention of posttherapeutic relapse remains to be elucidated. In this work, the aim was to characterize the gene expression profile by quantitative real-time polymerase chain reaction (qPCR) of proinflammatory and regulatory biomarkers that are typically associated with ENP and to assess the impact of the topical application of mitomycin C on the nasal mucosal tissue immunologic milieu after ENP surgery. METHODS: We have selected 20 patients with ENP that were recommended to undergo surgical intervention. Normal mucosal tissue was obtained from healthy nasal mucosa from six patients with absence of eosinophilic infiltration. To test the effect of mitomycin C, one side of the maxillary sinus mucosa was selected for topical application of this drug and the other received no further treatment and acted as the control. The genes interleukin-4 (IL-4), IL-5, IL-10, IL-13, chemokine (C-C motif) ligand 5 (CCL5), CCL24, colony-stimulating factor 2 (CSF2), transforming growth factor beta 1 (TGFB1), tumor necrosis factor alpha (TNF-alpha), and beta actin (ACTB) were selected for gene expression analysis by qPCR. RESULTS: The data showed higher expression of proinflammatory biomarkers and lower levels of regulatory TGFB1 transcripts in ENP mucosal tissue. Surgery with topical application of mitomycin C induced a prominent transcriptional down-regulation of the immunologic biomarkers, CCL24, TNF-alpha, CSF2, and IL-5, in ENP mucosal tissue. Additionally, this treatment restored the levels of chemokines and cytokines to those observed in the nasal mucosal tissue of control subjects, except for TGFB1, which remained below the reference pattern. Moreover, CSF2 was identified as a putative biomarker with significant predictive value for complementary prophylactic purposes after surgery in ENP patients. CONCLUSION: After the characterization of the expression signatures of immunologic biomarkers in ENP, we observed that the topical use of mitomycin C is important for the reestablishment of the immunologic microenvironment of a normal expression profile of biomarkers involved in ENP mucosal tissue.

Trace elements in nasal polyps.

The aim of our study is to evaluate the status of selenium and zinc in nasal polyp tissues and to investigate the possible role of trace elements and antioxidants including superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in nasal polyps. In this study, the antioxidant enzyme and trace element levels measured in polyp tissues of 37 patients were compared with the levels measured in conchal mucosa of 27 control cases. The antioxidant enzyme and trace element levels in tissues were measured with graphite and flame spectrophotometry methods using Shimatsu UV.1601 spectrophotometer and Perkin Elmer atomic spectrometer. The mean tissue zinc and selenium levels were, respectively, 2.55 µg/g and 30.03 pg/g in patient group, 4.37 µg/g and 44.95 pg/g in control group. The mean tissue SOD and GSH-Px levels were, respectively, 4.27 and 0.69 U/mg protein in patient group, 7.09 and 0.77 U/mg protein in control group. When the measured levels in patients and control cases were compared, there were statistically significant differences between zinc, selenium, and SOD levels (P = 0.001). There was no significant difference between GSH-Px levels (P = 0.465). In conclusion, it has been revealed that the levels of zinc, selenium, and SOD in nasal polyps were significantly lower, and it may be concluded that this may have a role in the development of nasal polyps.

Evaluation of bacterial adherence and biofilm arrangements as new targets in treatment of chronic rhinosinusitis.

Several promising candidate drugs that target bacterial adherence and biofilm formation are being developed. Such hopeful drugs cannot be studied in chronic rhinosinusitis (CRS) without the evaluation of such virulence criteria in different forms of the disease with and without nasal polyposis (CRSwNP and CRSsNP). The aim of this study was to evaluate bacterial adherence, response to antibiotics and degree of accumulation of bacterial biofilms as new targets of treatment in CRSwNP and CRSsNP. Twenty CRS patients and 10 normal subjects with airway obstructing concha bullosa were prospectively enrolled in the present study. Scanning electron microscopy and cultures were performed on paranasal sinus tissue samples. Bacterial adherence tests using the tissue culture plate method were measured quantitatively. Strongly adherent bacteria were identified significantly in 6/9 (77%) cases of CRSsNP in comparison to 1/7 (14%) cases of CRSwNP. Strongly adherent bacteria that were sensitive to ciprofloxacin, vancomycin, and impenim were identified in 75% of the cultured coagulase positive staphylococci. A significant difference (P = 0.007) in the degree of accumulation of bacterial biofilms existed between the two groups. In CRSsNP, a more advanced stage of bacterial biofilms with strong bacterial adherence was observed which make them attractive targets for new drugs. In CRSwNP, lower stage bacterial biofilms with low bacterial adhesion were identified, which may help explain the low bacterial virulence in an environment of suboptimal, organizational arrangements.

Epinephrine/Lidocaine injection vs. saline during endoscopic sinus surgery.

OBJECTIVES: To assess the safety and effectiveness of an epinephrine/lidocaine mixture administered by injection versus epinephrine administered topically and to learn its pharmacokinetics following administration to the nasal mucosa. DESIGN: A double-blind randomized controlled trial. METHODS: Patients were assigned into two groups and were injected with either epinephrine 1:100,000 and lidocaine 1% or saline alone during endoscopic nasal surgery under general anesthesia. Pledgets soaked in epinephrine 1:1,000 were used throughout the procedure in both groups. Hemodynamic measurements and catecholamine blood levels were obtained. RESULTS: Ten patients were randomized to the epinephrine group and 12 to the saline group. We were able to measure epinephrine and norepinephrine levels following injection in all patients. Epinephrine levels were similar in both groups immediately after injection; however, 15 minutes following injection, epinephrine was significantly higher in saline-injected patients. Mean arterial pressure and heart rate were affected by epinephrine and norepinephrine levels immediately after injection but were never elevated over the normal range. Heart rate was higher (P < .05) in the saline injected group than in the epinephrine group throughout the measurement period. The surgeons believed that the surgical field was bloodier in saline-injected patients (P < .05) however objective estimation of blood loss showed no difference. CONCLUSIONS: Injection of epinephrine/lidocaine mixture does not produce higher blood levels of epinephrine when compared to saline injection and did not induce any harmful side effects. We postulate that the combination with lidocaine 1% may reduce the patients' stress and thus prevent higher catecholamine levels.

Microscopic endonasal surgery of nasal and paranasal cavities.

OBJECTIVE: To present the experience of our department on microscopic surgery of the nose and sinuses and compare our results with those of other standard approaches. Furthermore we attempt to specify the main indications for the use of the method. METHODS: During the period between January 1990 and December 2002, the prementioned technique was performed in a total of 250 patients. The preoperative evaluation, surgical technique and postoperative management of all patients are described in detail. RESULTS: Most common diagnoses included nasal polyps and chronic rhinosinusitis. The average age of patients was 42 years. Males accounted for 48%. No major postoperative complications were noted. Minor complications such as epistaxis and midfacial pain were observed in 24% of cases. While the majority of patients reported severe symptomatology preoperatively, 91% reported substantial improvement of their clinical condition within 3 months after surgery. CONCLUSION: Microscopic surgery is a technique which can be used alternatively to traditional procedures. It provides an excellent, clear, stereoscopic vision and allows the surgeon to work bimanually. Complications are rare and easily controlled. Our experience favors the use of microscopic technique compared to common endoscopic approaches, especially in cases of nasal polyps and chronic rhinosinusitis.

Effects of dexmedetomidine infusion in patients undergoing functional endoscopic sinus surgery under local anaesthesia.

BACKGROUND AND OBJECTIVES: Functional endoscopic sinus surgery can be performed under either local or general anaesthesia. The objective of this study was to investigate the haemodynamic effects of perioperatively administered dexmedetomidine, a new generation alpha-2-agonist, in patients for functional endoscopic sinus surgery. METHODS: Sixty-two patients who were planned to undergo functional endoscopic sinus surgery under local anaesthesia were included in the study. Following meperidine premedication, both groups were monitored in a standard manner with electrocardiogram, non-invasive blood pressure and percentages of peripheral saturation of oxygen. Saline intravenous infusion was started in the placebo group, and dexmedetomidine bolus intravenous infusion (an initial loading dose of 1 microg kg-1 given for a 10-min period followed by 0.7 microg kg-1 h-1) was administered to the treatment group. Maintenance dose infusion was stopped 15 min before the end of the surgical procedure. RESULTS: Systolic, diastolic and mean arterial pressures, and heart rate markedly decreased in the dexmedetomidine group. However, dexmedetomidine had no effect on serum nitric oxide levels, measured by a nitric oxide/ozone chemiluminescence method. No significant difference was found in oxygen saturation levels of the two groups. Postoperative nausea and vomiting rates were significantly lower in the dexmedetomidine group. No adverse effects were observed with this alpha-2-agonist. Dexmedetomidine provided appropriate levels of sedation. CONCLUSION: These results suggest that dexmedetomidine provides analgesia, adequate sedation and surgical comfort without adverse effects for patients undergoing functional endoscopic sinus surgery under local anaesthesia.

Ibuprofen therapy and nasal polyposis in cystic fibrosis patients.

OBJECTIVE: To assess the effects on nasal polyposis from high-dose ibuprofen therapy used in children with cystic fibrosis (CF) pulmonary disease. DESIGN: Retrospective case series. MAIN OUTCOME MEASURE: Presence or absence of nasal polyps. RESULTS: Twenty-two patients treated with high-dose ibuprofen therapy to benefit pulmonary function were identified from 235 patients with CF. Sinonasal disease was present in 19 patients, of whom 12 had nasal polyposis. All 12 patients had observed absence of nasal polyps at some point during their ibuprofen course. Nasal polyps were present in five patients during ibuprofen therapy, and all resolved with increased ibuprofen doses. Polyps occurred in six of eight patients after ibuprofen therapy ceased. Five of the 12 patients required endoscopic sinus surgery for polyposis. CONCLUSION: High-dose ibuprofen therapy chronically administered at appropriate weight-based dosing is a possible treatment option for children and young adults with CF polyposis. More testing is indicated.

Radiofrequency-induced thermotherapy on nasal polyps: preliminary results.

BACKGROUND: The aim of this study was to determine the effects of radiofrequency-induced thermotherapy (RFITT) in patients with nasal polyps. METHODS: A retrospective analysis was performed of prospectively collected data from 17 consecutive patients (11 men and 6 women; mean age, 51.7 +/- 16.9 years) treated with RFITT from 2002 to 2003. The postoperative outcome was assessed using active anterior rhinomanometry, "sniffin' stick" test, and endoscopic nasal examination preoperatively and 4 weeks postoperatively. Subjective complaints were assessed with Likert scales. RESULTS: Transnasal airflow increased by 40.3% 4 weeks postoperatively (p = 0.029). Endoscopic appearance of nasal polyps indicated a nonsignificant reduction of 37.1%. Subjective complaints such as impaired nasal ventilation (p = 0.014), nasal discharge (p = 0.0007), postnasal drip (p = 0.0002), and hyposmia (p = 0.048) improved significantly 4 weeks after surgery. CONCLUSION: RFITT is well tolerated as a day case procedure under local anesthesia and might be a procedure for treating recurrence of NP after sinus surgery. It remains unclear at this point whether RFITT for nasal polyps results in a permanent reduction.

[The use of the BrainLAB Kolibri navigation system in endoscopic paranasal sinus surgery under local anaesthesia. An analysis of 35 cases]. / Einsatz des Brainlab-Kolibri-Navigationssystems bei der endoskopischen Nasennebenhöhlenchirurgie in Lokalanästhesie. Erfahrung an 35 Patienten.

BACKGROUND: As a result of technological advances, 3D-navigation systems are playing an increasingly important role in paranasal sinus and anterior skull base surgery. PATIENTS AND METHODS: The BrainLAB Kolibri navigation system (BrainLAB, Heimstetten, Germany) was used in the surgical management of chronic sinusitis and nasal polyposis in 35 patients. Surgery was performed under local anaesthesia. In order to compare this technique with traditional methods, 35 additional patients underwent conventional surgery. A clinical plausibility test using specific anatomical landmarks was performed to evaluate intraoperative navigation accuracy. In addition, a standardised questionnaire was used to document setup and registration times. Standardised rating scales helped assess whether the system can make surgery safer. RESULTS: It took approximately 5.8 min to set up the navigation system. The time required for system and patient positioning, including the attachment of the headband, was 4.2 min on average. Patient registration with the z-touch system was completed after an average of 4.2 min. It took an average of approximately 8.1 min to register a patient using the soft-touch system. The use of the navigation system increased the total time for preparation and surgery by approximately 50% in comparison to the conventional technique. An average accuracy of 1.5-2.3 mm in all three planes was measured. Participating surgeons felt that the system made surgery considerably safer. CONCLUSIONS: The BrainLAB Kolibri navigation system offers good accuracy, a short setup time and an easy registration technique. The combination of these qualities and intuitive operation make this system a suitable option for routine use in paranasal sinus surgery. As a result of its compactness, the BrainLAB Kolibri navigation system can be moved easily between different operating rooms and can also be used in small facilities (e.g. container operating theatres in field hospitals).

Office-based procedures in rhinosinusitis.

The availability of nasal endoscopes enables the rhinologist to visualize pathology in the posterior nasal cavity and middle meatus. With limited surgical equipment, the surgeon skilled in local anesthesia can perform biopsies, debridements, polypectomies, and turbinate reductions successfully in the office. With more specialized equipment and powered instrumentation,endoscopic maxillary antrostomies and other limited sinus surgeries become possible. On occasion, the surgeon might perform a limited ethmoidectomy,revise a sphenoidotomy, or remove polyps from within the maxillary sinus. For the properly selected patient, office surgery provides convenience and cost savings by eliminating hospital fees, anesthesia charges and preanesthesia testing. For the busy surgeon, office surgery allows improved efficiency by eliminating travel and anesthesia time.
