Postviral olfactory loss.

A viral upper respiratory infection is one of the most commonly identified causes of olfactory loss, accounting for 20% to 30% of patients in most series. Given the ubiquitous nature of upper respiratory infections, it is not clear what predisposes some patients to develop this complication. Studies have demonstrated degenerative changes within the olfactory epithelium, the severity of which seems to correlate with the severity of olfactory loss. Although no available therapy has proved effective, long-term follow-up data have found that approximately two thirds of these patients eventually experience a significant improvement in their olfactory function.

The clinical effects of hyaluronic acid ester nasal dressing (Merogel) on intranasal wound healing after functional endoscopic sinus surgery.

OBJECTIVES: We sought to determine the efficacy of MeroGel, an absorbable hyaluronic acid nasal dressing (HA) in reducing synechia after functional endoscopic sinus surgery (FESS) compared with Merocel, a nonabsorbable packing (NAP) requiring removal. METHODS: We conducted a blinded, randomized, controlled trial of 37 patients requiring bilateral FESS for chronic sinusitis. Patients were randomized to placement of HA within the right or left middle meatus and NAP on the other side. Patients were evaluated at 2, 4, 6, and 8 weeks postoperatively. RESULTS: Blinded evaluation revealed 5 patients (14%) with synechia at last follow-up: 3 sides (8%) with HA and 3 (8%) with NAP. Thirteen patients (35%) had synechia at any visit, 10 sides (27%) with HA and 9 (24%) with NAP. Seven patients (19%) required lysis of synechia, 5 sides (14%) with HA and 3 (8%) with NAP. CONCLUSION: We found no statistically significant difference between HA and NAP dressings.

Evidence supporting endoscopic sinus surgery in the management of adult chronic rhinosinusitis: a systematic review.

BACKGROUND: Evidence-based medicine calls for a critical evaluation of the scientific evidence for treatments of disease. This report synthesizes the available evidence on the use of endoscopic sinus surgery (ESS) in the management of adult chronic rhinosinusitis (CRS) examining the clinical question: "In adults with CRS who have failed medical management, does ESS improve symptoms and/or quality of life (QOL)?" METHODS: The American Rhinologic Society and the American Academy of Otolaryngology-Head and Neck Surgery convened a steering committee composed of the authors. Primary research articles evaluated for this report were identified using appropriate search terms and a Medline search. Two authors independently reviewed each article. Articles were assigned an evidence level based on accepted guidelines (level 1 = randomized trials; level 2 = prospective cohort studies with comparison group; level 3 = case-control studies; level 4 = retrospective case series; level 5 = expert opinion). RESULTS: We identified 886 abstracts to review, retrieved 75 articles for full review, and included 45 articles in our report. The vast majority of articles represented level 4 evidence (n = 42) and two articles represented level 5 evidence. One article was identified that qualified for level 2 evidence. All of these articles generally supported the finding that ESS improves symptoms and/or QOL in adult patients with CRS. CONCLUSION: There is substantial level 4 evidence with supporting level 2 evidence that ESS is effective in improving symptoms and/or QOL in adult patients with CRS. Future research efforts should focus on prospective studies that include appropriate comparison groups in their design.
