Recalcitrant chronic rhinosinusitis: investigation and management

Comprehensive review on endonasal endoscopic sinus surgery

Endonasal endoscopic sinus surgery is the standard procedure for surgery of most paranasal sinus diseases. Appropriate frame conditions provided, the respective procedures are safe and successful. These prerequisites encompass appropriate technical equipment, anatomical oriented surgical technique, proper patient selection, and individually adapted extent of surgery. The range of endonasal sinus operations has dramatically increased during the last 20 years and reaches from partial uncinectomy to pansinus surgery with extended surgery of the frontal (Draf type III), maxillary (grade 3-4, medial maxillectomy, prelacrimal approach) and sphenoid sinus. In addition there are operations outside and beyond the paranasal sinuses. The development of surgical technique is still constantly evolving. This article gives a comprehensive review on the most recent state of the art in endoscopic sinus surgery according to the literature with the following aspects: principles and fundamentals, surgical techniques, indications, outcome, postoperative care, nasal packing and stents, technical equipment.

Sinus penetration of saline solution irrigation and atomizer in a cadaveric polyp and allergic fungal sinusitis model

Allergic fungal sinusitis (AFS) is a stubborn disease requiring surgical and medical management. Delivery of topical medication is paramount in these patients, but the most difficult to accomplish. We investigated heavy irrigation (nasal douche) and atomized medication delivery potential in a cadaveric sinus model of polypoid AFS disease. Three disease models were created: a control that involved unoperated sinuses and no simulated disease; an unoperated AFS with type II polyposis mode; and an operated model with recurrent allergic fungal sinusitis with type II polyposis. The maxillary sinus showed the best irrigation and overall the heavy irrigator was more efficient than the atomizer.

Supraesophageal Reflux: Correlation of Position and Occurrence of Acid Reflux-Effect of Head-of-Bed Elevation on Supine Reflux

BACKGROUND

Supraesophageal reflux of gastric contents can contribute to perennial nasopharyngitis, cough, and asthma. However, effective treatment strategies for supraesophageal reflux disease (SERD) remain inadequately defined.

OBJECTIVE

The purpose of this study is to assess the prevalence and timing of SERD and to investigate the efficacy of head-of-bed elevation in its treatment.

METHODS

A retrospective chart review of patients seen at Scripps Clinic Division of Allergy, Asthma and Immunology was performed who had undergone overnight nasopharyngeal pH monitoring with a commercially available nasopharyngeal pH-monitoring device, Dx-pH Measurement System from Restech, San Diego, Calif. Subjects with reflux were classified based on the position of reflux as either supine only, upright only, or both supine and upright. In a subset of subjects with supine-only reflux, pH monitoring was compared before and after elevating the head of bed 6 inches.

RESULTS

Adequate nasopharyngeal pH-monitoring data were obtained for 235 patients. Reflux was detected in 113 (48%) patients. The pattern of reflux observed was 62 (55%) supine only, 4 (4%) upright only, and 47 (42%) upright and supine. Sequential overnight nasopharyngeal pH monitoring before and after head-of-bed elevation was obtained in 13 individuals with supine-only reflux. Ten subjects demonstrated significant improvement, 8 of whom demonstrated complete resolution of supine reflux with 6 inches of head-of-bed elevation.

CONCLUSION

This study provides new evidence that SERD frequently occurs in the supine position and that 6 inches of head-of-bed elevation is effective in reducing supine SERD.

Complementary and integrative treatments: rhinosinusitis

Rhinosinusitis is characterized by inflammation of the mucosa involving the paranasal sinuses and the nasal cavity and is one of the most common health care problems, with significant impairment of quality of life. There is a growing amount of interest in the use of complementary and integrative medicine for the treatment of rhinosinusitis. This article focuses on an integrative approach to rhinosinusitis.

Gastroesophageal reflux and chronic rhinosinusitis

PURPOSE OF REVIEW

Chronic rhinosinusitis (CRS) and gastroesophageal reflux disease (GERD) are two common conditions which have been reported to occur together more frequently than expected. It has, therefore, been proposed that GERD may have an aetiologic role in CRS. This study reviews the results of research into the possible reflux and reflex mechanisms that may link CRS and GERD.

RECENT FINDINGS

Robust assessment of gastric reflux into the nasopharynx using circumferential pH probes which are less subject to artefact have demonstrated that direct reflux into the nasopharynx is a rare event. Pepsinogen has only been found in the nasal cavity in one study which had unexpected results, raising doubts about the validity of the methodology. A reflex increase in nasal congestion and mucus secretion has been demonstrated experimentally, but in a small number of patients, which precluded statistical significance. The relationship between reflux and mucus secretion is supported, though, by randomized controlled trials showing decreased postnasal drip with proton-pump inhibitor therapy.

SUMMARY

Recent evidence suggests that GERD does not play a causative role in CRS. However, there is evidence of an oesophageal-nasal reflex, particularly in regard to mucus secretion and symptoms of postnasal drip. The presence of GERD would, therefore, be expected to worsen nasal symptom scores.

Managing upper respiratory tract complications of primary ciliary dyskinesia in children

PURPOSE OF REVIEW

Primary ciliary dyskinesia (PCD) is a rare and heterogeneous disease that is often misdiagnosed or diagnosed late with more advanced sequelae. PCD primarily effects the respiratory tract, yet most research focuses on the lower respiratory tract manifestations, most of which is derived from research on cystic fibrosis. Little is known about the management of the upper respiratory tract sequelae of PCD. This review summarizes the available evidence for the management of otologic and sinonasal manifestations of PCD.

RECENT FINDINGS

The natural history of otitis media with effusion and hearing loss in PCD appears to fluctuate into adulthood and does not resolve by the age of 9 years, regardless of treatment, as previously assumed. Ventilation tube insertion improves hearing in PCD, but may lead to a higher rate of otorrhoea when compared with the general population. Sinonasal disease in PCD is poorly studied; however, it appears that patients with chronic rhinosinusitis (CRS) may benefit from long-term macrolide therapy and endoscopic sinus surgery (ESS) in recalcitrant disease. Therapies targeted at improving mucociliary clearance have not been tested specifically in PCD. Pharmacogenetic therapy is currently under investigation to target the primary defect in PCD.

SUMMARY

Otologic sequeale in PCD should undergo lifelong evaluation and monitoring and ventilation tube insertion should be considered to avoid complications of chronic hearing loss. Sinonasal disease benefits from macrolide therapy and ESS. Randomized controlled trials of treatment efficacy of the upper respiratory tract manifestations of PCD are lacking.

Sinonasal outcome under aspirin desensitization following functional endoscopic sinus surgery in patients with aspirin triad

Recalcitrant forms of recurrent nasal polyposis are problematic for patients as for rhinosurgeons. In aspirin-sensitive patients, aspirin desensitization is supposed to prevent recurrence by targeting the metabolism of arachidonic acid. Aspirin-sensitive patients (n = 65) following aspirin desensitization after functional endoscopic sinus surgery (FESS) for recurrent nasal polyposis under daily intake of 500-mg aspirin were compared to a post-FESS group (n = 81) of aspirin-sensitive individuals using exclusively topical mometasone. Quality of life (QoL) scores including sinonasal, pulmonal and general QoL items as well as endoscopic endonasal examination findings were evaluated during the postoperative follow-up period. After a follow-up period of minimum 18 months, a significant improvement in nasal obstruction, rhinorrhea, post nasal drip, sense of smell, facial pain, sleep quality and further general QoL items in desensitized patients was found compared to aspirin-sensitive controls. Improvement in sinonasal symptoms was evident, whereas the severity of asthmatic symptoms showed no significant changes. Although the pathophysiology of aspirin sensitivity is still not fully understood and the therapy is not sufficiently investigated, aspirin desensitization seems to have a positive effect on QoL scores concerning sinonasal symptoms and should be regarded as a possible postoperative treatment modality for recurrent nasal polyposis in aspirin-sensitive individuals.
