Clinical study and literature review of nasal irrigation.

OBJECTIVES/HYPOTHESIS: Nasal disease, including chronic rhinosinusitis and allergic rhinitis, is a significant source of morbidity. Nasal irrigation has been used as an adjunctive treatment of sinonasal disease. However, despite an abundance of anecdotal reports, there has been little statistical evidence to support its efficacy. The objective of this study was to determine the efficacy of the use of pulsatile hypertonic saline nasal irrigation in the treatment of sinonasal disease. STUDY DESIGN: A prospective controlled clinical study. METHODS: Two hundred eleven patients from the University of California, San Diego (San Diego, CA) Nasal Dysfunction Clinic with sinonasal disease (including allergic rhinitis, aging rhinitis, atrophic rhinitis, and postnasal drip) and 20 disease-free control subjects were enrolled. Patients irrigated their nasal cavities using hypertonic saline delivered by a Water Pik device using a commercially available nasal adapter twice daily for 3 to 6 weeks. Patients rated nasal disease-specific symptoms and completed a self-administered quality of well-being questionnaire before intervention and at follow-up. RESULTS: Patients who used nasal irrigation for the treatment of sinonasal disease experienced statistically significant improvements in 23 of the 30 nasal symptoms queried. Improvement was also measured in the global assessment of health status using the Quality of Well-Being scale. CONCLUSIONS: Nasal irrigation is effective in improving symptoms and the health status of patients with sinonasal disease.

Local hyperthermia and nasal irrigation for perennial allergic rhinitis: effect on symptoms and nasal airflow.

Local hyperthermia or inhalation of heated water vapor is often recommended as a home remedy for various nasal disorders such as the common cold and allergic rhinitis. With technical advances in vapor generation, water can be heated to a range of 41 degrees C to 43 degrees C with variation in particle size. The effect of inhaled heated vapor treatments was studied in patients with perennial rhinitis for changes in nasal airflow and patient perception of symptoms. Thirty symptomatic patients underwent three treatments at weekly intervals: (1) a large particle heated water vapor at 43 degrees C for 20 minutes with a particle size of 4 to 8 microns, (2) a molecular water vapor at 41 degrees C for 20 minutes which is a vapor phase, and (3) nasal irrigation. Nasal airflow increased after both vapor treatments at four and six hours (P < .05) whereas airflow decreased after simple nasal irrigation treatment. Rhinitis symptoms improved after vapor treatments but not with nasal irrigation. Patients preferred the molecular water vapor treatment over the large particle vapor treatment and nasal irrigation by 2:1 margin. This study demonstrated the usefulness of heated vapor treatments in improving rhinitis symptoms and nasal airflow.

Nasal irrigations: good or bad?

PURPOSE OF REVIEW: Nasal irrigations are often mentioned as adjunctive measures in treating many sinonasal conditions. Despite their widespread use, much mystique and uncertainty exist about the indications and therapeutic mechanisms of nasal irrigations. Anecdotal evidence and poorly controlled studies add to the confusion. Recent evidence challenges some of the assumptions underlying the use of nasal irrigations. RECENT FINDINGS: Studies of nasal irrigations continue to report the benefits in managing sinonasal complaints. Apart from improved patient symptomatology, prescription medication use is often decreased. When nasal irrigations are combined with other medical modalities, patients with chronic sinusitis may not require surgical intervention as often. In particular, patients using hypertonic saline nasal irrigations reported better outcomes. Different devices and techniques exist. Positive-pressure and negative-pressure methods are probably more effective than nebulizers. Furthermore, the popular belief that nasal irrigations need to be sterile is in question. SUMMARY: Nasal irrigations should no longer be considered merely adjunctive measures in managing sinonasal conditions. They are effective and underutilized. Some of the persisting unanswered questions will only be answered by further research.

[Nasal irrigation in case of rhinosinusitis].

Nasal irrigation has proven in several recently published articles its clinical effectiveness and its neglectable rate of side effects even in children and during pregnancy. In most guidelines for the treatment of various nasal pathological conditions nasal irrigation is recommended as stand alone or as additional therapy. Although no common treatment protocol exists, a isotonic (0.9 %) or slightly hypertonic solution (3 - 5 %) is suggested because of its positive influence upon mucociliary clearance. Buffered solutions bring a more pleasant feeling during rinsing, which explains also the beneficial effect of natural brine solutions. In children, nasal irrigation can save antibiotics and reduce decongestant to nil. Important is the hygienic application in order not to introduce additional pathogenic germs into the nasal system.

Systemic absorption of gentamicin nasal irrigations.

OBJECTIVE: To determine if gentamicin nasal irrigation is systemically absorbed, and to identify any ototoxic side effects related to its use. DESIGN: Retrospective review of 12 patients treated with gentamicin nasal irrigations (30 cc of 80 mg/L solution used bilaterally twice daily). METHODS: Serum gentamicin levels were assayed after the course treatment. Pure tone audiometry (250-8000 Hz) and distortion product otoacoustic emissions (DP-OAEs) at 7280, 5133, 3640 and 2560 Hz were obtained before and after therapy. RESULTS: Twelve patients (age 4 to 74, mean 43) with chronic rhinosinusitis were treated for 3-15 weeks (mean 7 weeks). All patients had undergone previous endoscopic sinus surgery. Ten patients had pretreatment cultures that grew organisms sensitive to gentamicin (Pseudomonas, Proteus, or methacillin resistant Staphylococcus aureus), and three patients had cystic fibrosis. Ten of 12 patients (83%) had detectable posttreatment levels of gentamicin, with a mean serum level of 0.42 mcg/mL (range 0.3 to 0.7 mcg/mL). Four of 12 patients (33%) had serum gentamicin levels within the normal range for gentamicin trough (0.5 to 2 mcg/mL). Comparison of pre- and posttreatment audiologic data revealed no significant change in PTA or DP-OAE, except for the right ear at 8000 Hz on PTA (p = 0.035) where a mean of 7 dB loss was observed. No patient reported hearing loss or vertigo during treatment. CONCLUSION: Gentamicin nasal irrigation may be systemically absorbed. Although the otologic consequences of this finding are questionable, patients receiving gentamicin nasal irrigations should be counseled regarding this hypothetical possibility.

Nasal irrigation for the alleviation of sinonasal symptoms.

OBJECTIVE: To determine the effect of nasal irrigation on sinonasal symptoms. STUDY DESIGN AND SETTING: A total of 150 adult subjects with chronic sinusitis symptoms were recruited from the community and assigned to 1 of 3 treatment groups: nasal irrigation with bulb syringe, nasal irrigation with nasal irrigation pot, or control treatment with reflexology massage. Groups 1 and 2 performed daily hypertonic saline irrigation with 1 device for 2 weeks and then with the other device for 2 weeks. Group 3 performed reflexology massage daily for 2 weeks. Prospective data collected included pretreatment Medical Outcomes Study Short Form, pretreatment and posttreatment Rhinosinusitis Outcomes Measure, daily medication use, subjective treatment efficacy, and preference of irrigation method. RESULTS: There was a significant and equivalent improvement in Rhinosinusitis Outcomes Measure 31 score after 2 weeks of intervention in each treatment group; 35% of subjects reported decreased use of sinus medication. CONCLUSION: Daily nasal irrigation using either a bulb syringe, nasal irrigation pot, and daily reflexology massage were equally efficacious and resulted in improvement in the symptoms of chronic sinusitis in over 70% of subjects. Medication usage was decreased in approximately one third of participants regardless of intervention.

A comparative study of three methods of nasal irrigation.

OBJECTIVE: To assess the effectiveness of three methods of nasal irrigation on distributing saline to the nasal cavity and paranasal sinuses. DESIGN: : A prospective, cross-over study. MATERIALS AND METHODS: Twelve subjects (9 patients with chronic sinusitis after functional endoscopic sinus surgery and 3 healthy controls) underwent nasal irrigation with normal saline containing Technetium 99m sulfur colloid. The distribution of radioactivity was assessed on each subject after three different irrigation techniques: metered nasal spray, nebulization with RinoFlow, and nasal douching while kneeling with the head on the floor. RESULTS: The nasal cavity was well irrigated by all three techniques. Compared with the other two methods, douching was significantly more effective in penetrating the maxillary sinus (P = .036) and frontal recess (P = .003). The sphenoid and frontal sinuses were poorly irrigated by all three techniques. CONCLUSION: Nasal douches are more effective in distributing irrigation solution to the maxillary sinus and frontal recess. This should be the method of choice for irrigating these areas.

Hypersaline nasal irrigation in children with symptomatic seasonal allergic rhinitis: a randomized study.

Recent evidence suggests that nasal irrigation with hypertonic saline may be useful as an adjunctive treatment modality in the management of many sinonasal diseases. However, no previous studies have investigated the efficacy of this regimen in the prevention of seasonal allergic rhinitis-related symptoms in the pediatric patient. Twenty children with seasonal allergic rhinitis to Parietaria were enrolled in the study. Ten children were randomized to receive three-times daily nasal irrigation with hypertonic saline for the entire pollen season, which had lasted 6 weeks. Ten patients were allocated to receive no nasal irrigation and were used as controls. A mean daily rhinitis score based on the presence of nasal itching, rhinorrea, nasal obstruction and sneezing was calculated for each week of the pollen season. Moreover, patients were allowed to use oral antihistamines when required and the mean number of drug assumption per week was also calculated. In patients allocated to nasal irrigation, the mean daily rhinitis score was reduced during 5 weeks of the study period. This reduction was statistically significantly different in the 3th, 4th and 5th week of therapy. Moreover, a decreased consumption of oral antihistamines was observed in these patients. This effect became evident after the second week of treatment and resulted in statistically significant differences during the 3th, 4th and 6th week. This study supports the use of nasal irrigation with hypertonic saline in the pediatric patient with seasonal allergic rhinitis during the pollen season. This treatment was tolerable, inexpensive and effective.

Saline nasal irrigation: Its role as an adjunct treatment.

OBJECTIVE: To review clinical evidence on the efficacy of saline nasal irrigation for treatment of sinonasal conditions and to explore its potential benefits. QUALITY OF EVIDENCE: Clinical trials, reviews, and treatment guidelines discussing nasal irrigation were obtained through a MEDLINE search from January 1980 to December 2001. Most trials were small and some were not controlled; evidence, therefore, is level II, or fair. MAIN MESSAGE: Flushing the nasal cavity with saline solution promotes mucociliary clearance by moisturizing the nasal cavity and by removing encrusted material. The procedure has been used safely for both adults and children, and has no documented serious adverse effects. Patients treated with nasal irrigation rely less on other medications and make fewer visits to physicians. Treatment guidelines in both Canada and the United States now advocate use of nasal irrigation for all causes of rhinosinusitis and for postoperative cleaning of the nasal cavity. CONCLUSION: Nasal irrigation is a simple, inexpensive treatment that relieves the symptoms of a variety of sinus and nasal conditions, reduces use of medical resources, and could help minimize antibiotic resistance.

Efficacy of daily hypertonic saline nasal irrigation among patients with sinusitis: a randomized controlled trial.

OBJECTIVES: To test whether daily hypertonic saline nasal irrigation improves sinus symptoms and quality of life and decreases medication use in adult subjects with a history of sinusitis. STUDY DESIGN: Randomized controlled trial. Experimental subjects used nasal irrigation daily for 6 months. POPULATION: Seventy-six subjects from primary care (n=70) and otolaryngology (n=6) clinics with histories of frequent sinusitis were randomized to experimental (n=52) and control (n=24) groups. OUTCOMES MEASURED: Primary outcome measures included the Medical Outcomes Survey Short Form (SF-12), the Rhinosinusitis Disability Index (RSDI), and a Single-Item Sinus-Symptom Severity Assessment (SIA); all 3 were completed at baseline, 1.5, 3, and 6 months. Secondary outcomes included daily assessment of compliance and biweekly assessment of symptoms and medication use. At 6 months, subjects reported on side effects, satisfaction with nasal irrigation, and the percentage of change in their sinus-related quality of life. RESULTS: No significant baseline differences existed between the 2 groups. Sixty-nine subjects (90.8%) completed the study. Compliance averaged 87%. Experimental group RSDI scores improved from 58.4 -/+ 2.0 to 72.8 -/+ 2.2 (P < or =.05) compared with those of the control group (from 59.6 -/+ 3.0 to 60.4 -/+ 1.1); experimental group SIA scores improved from 3.9 -/+ 0.1 to 2.4 -/+ 0.1 (P < or =.05) compared with those of the control group (from 4.08 -/+ 0.15 to 4.07 -/+ 0.27). The number needed to treat to achieve 10% improvement on RSDI at 6 months was 2.0. Experimental subjects reported fewer 2-week periods with sinus-related symptoms (P <.05), used less antibiotics (P <.05), and used less nasal spray (P =.06). On the exit questionnaire 93% of experimental subjects reported overall improvement of sinus-related quality of life, and none reported worsening (P <.001); on average, experimental subjects reported 57 -/+ 4.5% improvement. Side effects were minor and infrequent. Satisfaction was high. We found no statistically significant improvement on the SF-12. CONCLUSIONS: Daily hypertonic saline nasal irrigation improves sinus-related quality of life, decreases symptoms, and decreases medication use in patients with frequent sinusitis. Primary care physicians can feel comfortable recommending this therapy.

Clinical and nasal irrigation fluid findings in perennial allergic rhinitis.

Ten patients with perennial allergic rhinitis and 10 healthy subjects were studied to determine most discriminative nasal irrigation fluid marker(s) and to compare samples that were collected at baseline and over a 1-hour period, every 15 minutes. The latter were pooled and designated 1-hour sample. In the nasal irrigation we investigated the following inflammatory cells and soluble mediators: eosinophils, neutrophils, granulocyte-macrophage colony-stimulating factor, interleukin-4, interleukin-6, interleukin-8, ECP, EPX, MPO, leukotriene C4, leukotriene B4, prostaglandin E2, tryptase and fibrinogen. Patients with PAR were then treated for 2 weeks with the topical nasal steroid. The only marker that discriminated patients with perennial allergic rhinitis and healthy subjects was eosinophil count (EO%): correspondingly 14.01 +/- 5.8 and 0.18 +/- 0.09, (M +/- SD). Difference between the studied groups did not depend on the time of irrigation, baseline or 1-hour. EO% was also the only marker of a clinically successful treatment with the nasal steroid, 14.01 +/- 5.8 and 0.87 +/- 0.4, before and after treatment respectively. We conclude that EO% is the most sensitive inflammatory marker of perennial allergic rhinitis, and that baseline nasal irrigation can be used to study nasal mucosal inflammation.

A randomized, prospective, double-blind study on the efficacy of dead sea salt nasal irrigations.

OBJECTIVE: The objective of this randomized, prospective, double-blind study was to compare nasal irrigation using hypertonic Dead Sea salt (DSS) solution with hypertonic saline in the treatment of chronic rhinosinusitis and improvement of quality of life (QOL). METHODS: With Institutional Review Board approval, 42 adults seeking treatment for chronic rhinosinusitis in a tertiary university-affiliated medical center were studied. After history and endonasal examination, computed tomography imaging, and QOL survey (Standardized Rhinoconjunctivitis Quality of Life Questionnaire [RQLQ(S)]), patients were randomized to self-administered hypertonic saline spray and irrigation twice daily or hypertonic DSS spray and irrigation. Patients were reassessed weekly and at 1 month. RESULTS: Both groups had similar symptoms and RQLQ(S) scores before treatment and had significant improvement after treatment. However, the DSS patients had significantly better symptom relief and only the DSS group showed improved RQLQ(S) scores. CONCLUSIONS: We present a short-term study providing level I evidence on the superiority of DSS over saline nasal irrigation for treatment of chronic rhinosinusitis.

Qualitative aspects of nasal irrigation use by patients with chronic sinus disease in a multimethod study.

PURPOSE: We qualitatively assessed attitudes regarding use of hypertonic saline nasal irrigation (HSNI) for frequent rhinosinusitis and chronic sinonasal symptoms in a 3-part, multimethod study. METHODS: We conducted semistructured, in-depth interviews with 28 participants who recently used nasal irrigation in studies assessing HSNI. RESULTS: Four themes emerged: (1) HSNI improved self-management of sinus symptoms, creating a sense of empowerment; (2) HSNI produced rapid and long-term improvement in quality of life; (3) participants identified discomfort, time, and mild side effects as barriers to HSNI use; and (4) participants identified aspects of training and at-home use that overcame these barriers. CONCLUSION: HSNI is a safe, well-tolerated, inexpensive, effective, long-term therapy that patients with chronic sinonasal symptoms can and will use at home with minimal training and follow-up. Success with HSNI will likely be improved by patient education.

The Statistical Fragility of Saline Nasal Irrigation for Rhinosinusitis: A Systematic Review.

OBJECTIVE: To assess the statistical fragility of randomized controlled trials (RCTs) evaluating high-volume saline nasal irrigation (SNI) for rhinosinusitis using fragility analysis. DATA SOURCES: PubMed, MEDLINE, and Embase were searched for RCTs published between May 1976 and January 2026. REVIEW METHODS: This study was reported as per PRISMA guidelines. RCTs that compared high-volume SNI to non-irrigation standard care for acute, recurrent, or chronic rhinosinusitis, and reported &#x2265;&#x2009;1 dichotomous outcome, were included. Fragility index (FI), the minimum number of event reversals needed to alter statistical significance, and fragility quotient (FQ), FI normalized to sample size, were calculated for statistically significant dichotomous outcomes. Reverse FI (rFI) and reverse FQ (rFQ) were calculated for non-significant outcomes. RESULTS: Eight RCTs were included, yielding 38 dichotomous outcomes. Eight outcomes (21.1%) were statistically significant. The overall combined median FI was 5 (FQ 0.062), with similar FI values between significant and non-significant outcomes. In over one-fifth of outcomes, loss to follow-up exceeded FI. Analysis of principal dichotomous outcomes from studies demonstrated a median FI of 6 (FQ 0.092), with five of eight (62.5%) outcomes non-significant. CONCLUSION: RCTs evaluating SNI for rhinosinusitis exhibit moderate-to-high statistical fragility, with small outcome changes capable of reversing study conclusions. Because fragility analysis was limited to dichotomous outcomes while many primary endpoints were continuous, our findings should be interpreted as complementary rather than comprehensive appraisals of RCTs. Future RCTs with larger sample sizes, reduced bias, and pre-specified fragility considerations are needed to better define the clinical role of SNI.

Immunohistochemical studies of the cellular changes in the peripheral olfactory system after zinc sulfate nasal irrigation.

The peripheral olfactory system has a remarkable capacity for repair. We have performed an immunohistochemical study of the cellular changes that occur after zinc sulfate irrigation of the nasal cavity. The rapid loss of epithelial cells was followed by the proliferation of basal cells and the restoration of the epithelium with olfactory tissue. Horizontal basal cell markers, anti-cytokeratin 5/6 (CK5/6), and the Bandeiraea simplicifolia (BS-1) lectin initially co-localized on day 1 after treatment but rapidly displayed a disparity in their staining profile, with CK5/6 immunoreactive cells having a profile more akin to cells expressing the sustentacular marker cytokeratin 18 (CK18). This suggests CK5/6 and BS-1 label a different subset of horizontal basal cells. Axonal degeneration and regeneration was studied with a panel of markers to olfactory receptor neurons, their terminals, and olfactory bulb dendrites. The glial cells of the peripheral olfactory system, olfactory ensheathing cells, remained in position, with little change in immunoreactivity to laminin, although an increase in the expression of glial fibrillary acidic protein was observed. The events and the extent of reconstitution of the olfactory system after degeneration serves as a foundation for future studies designed to understand the unique regenerative capacity of the olfactory system.

The efficacy of hypertonic saline nasal irrigation for chronic sinonasal symptoms.

OBJECTIVE: To assess quality of life (QOL) in patients with sinonasal symptoms in response to hypertonic saline nasal irrigation (HSNI), and to assess HSNI use patterns. STUDY DESIGN AND SETTING: The study was an uncontrolled 12-month follow-up to a randomized controlled trial (RCT) and used HSNI in a community setting. We included 54 participants with recurrent or chronic sinonasal symptoms. Forty participants had been in the intervention group of a previous study; 14 had been control participants. Primary outcome measures were the Rhinosinusitis Disability Index (RSDI), a sinus-symptom severity assessment (SIA), and the Sino-Nasal Outcomes Test (SNOT-20). Secondary outcome measures were frequency and pattern of HSNI use, side effects and satisfaction. RESULTS: Among participants using HSNI in the prior RCT, RSDI scores continued to improve, from 73.2 +/- 2.6 points to 80.6 +/- 2.4 points (P < 0.001). SIA and SNOT-20 scores remained stable. Former control participants reported QOL improvement similar to that of HSNI users in the prior RCT. RSDI scores improved from 62.0 +/- 3.9 points to 79.7 +/- 3.7 points (P < 0.05), SNOT-20 scores improved from 43.5 +/- 5.7 points to 28.4 +/- 4.8 points, and SIA scores improved from 4.2 +/- 0.3 points to 2.6 +/- 0.3 points (P < 0.01). Mean HSNI use for all participants was 2.4 irrigations per week; 33% of participants used HSNI regularly, 55% when symptomatic. Side effects were minor; satisfaction was high. CONCLUSIONS: Participants with chronic sinonasal symptoms reported improved QOL and frequent, satisfying use of HSNI. SIGNIFICANCE: HSNI is an effective adjunctive treatment of chronic sinonasal symptoms.
