Can sinus anatomy predict quality of life outcomes and operative times of endoscopic frontal sinus surgery?

ABSTRACT: Endoscopic sinus surgery (ESS) can manipulate sinus anatomy, but with limitations due to skull base and orbit anatomy. These anatomical structures dictate the maximal extent of ESS in the frontal recess and may limit surgical extent or operative duration. This study investigates the impact of these anatomical constraints on operative time and quality-of-life (QOL) outcomes.Patients with medically refractory chronic rhinosinusitis undergoing Draf IIa frontal sinus surgery were prospectively enrolled. Anatomic measurements of the frontal sinus anatomy were collected during computed tomography review and included: widest distance between the frontal beak and posterior table, narrowest point in the ethmoid bed, Keros height, presence of an anterior ethmoid artery on a mesentery, and presence of inter-sinus septal cells. Primary outcomes included mean operative time and improvement in SinoNasal Outcome Test (SNOT-22) survey scores.63 adult participants were enrolled and followed 13.8 (5.2) months on average. The ethmoid bed mean width was 7.2 (1.4) mm, the mean distance from frontal beak to the posterior table at widest was 9.0 (2.7) mm, and mean Keros height was 5.1 (1.8) mm. 49/63 (83.1%) of participants had inter-sinus septal cells and 30/63(50.8%) had anterior ethmoid arteries on a mesentery. Mean operative time was 121.5 (44.0) min while SNOT-22 scores significantly (p<0.001) improved 26.1 (21.6) on average. Anatomic measurements were not predictive of operative time or mean QOL change (p>0.050).Frontal sinus surgery is an effective treatment for a range of frontal and ethmoid sinus anatomy. Further study with larger sample size and measures of more restricted anatomy might elucidate treatment limitations of ESS.

Project description:INTRODUCTION:Although significant experience has been gained in the technical nuances of endoscopic sinus surgery procedures, the patient-reported outcomes of frontal endoscopic sinus surgery procedures are still poorly understood. In this study we used the validated patient outcome measure Sino Nasal Outcome Test-22 (SNOT-22) to assess the preoperative and postoperative quality of life in patients undergoing extended endoscopic frontal sinus surgery (Draf type 2 and Draf type 3 procedures). METHODS:Out of a total of 680 patients undergoing endoscopic sinus and skull base surgery and 186 patients undergoing frontal sinus surgery, 99 chronic rhinosinusitis patients with (CRSwNP) or without (CRSnNP) nasal polyps undergoing Draf 2 or Draf 3 were assessed. RESULTS:The mean preoperative SNOT-22 was 45.6 points for patients undergoing Draf 2 and 59 for patients undergoing Draf 3, while the mean radiological Lund-Mackay Score was 14.3 and 14.5, respectively. Mean SNOT 22 improvement was 22.9 points for Draf 2 and 37 points for Draf 3 respectively and remained significant in all time intervals, including at 4 years after surgery. With the exception of loss of smell/taste, all symptoms improved by a far bigger extent in Draf 3 group, despite the considerably worse starting point. Effect size (Cohen / Standard Deviations) of Draf 3 was greatest in the following symptoms: "being frustrated/restless/irritable" (1.63), "nasal blockage" (1.43), "reduced concentration" (1.35), "fatigue" (1.29) "runny nose" (1.26) and "need to blow nose" (1.17). Frontal sinus (neo) ostium was patent (fully or partly) at last follow up in 98% of Draf 2 patients and in 88% of patients following Draf 3. Patients with non-patent frontal (neo-) ostium however had a mean postoperative SNOT 22 score of 43 compared to 20 of those with patent frontal sinus (neo-) ostium, although the difference was not statistically significant. CONCLUSION:Patients undergoing Draf 3 have a greater burden of disease, including both nasal and emotional/general symptoms compared to Draf 2 patients; surgery results in improvement in both groups, although Draf 3 patients have the greatest benefit, especially in emotional / general symptons. In this way both groups achieve similar postoperative quality of life, despite the different starting points.

Project description:OBJECTIVES:There is little consensus regarding the prognostic value of symptom duration in predicting clinical disease severity or quality-of-life (QOL) outcomes in patients with chronic rhinosinusitis (CRS). Our objectives were to: 1) determine if patients with longer symptom duration have worse preoperative disease severity and/or QOL, and 2) determine if delayed surgical intervention influences outcomes of endoscopic sinus surgery (ESS). METHODS:Patients diagnosed with CRS were prospectively enrolled into a multicenter cohort study and observed 14.7 (standard deviaton {SD}?±?4.8) months on average following primary ESS. Preoperative symptom duration was stratified into short-term (<?12 months), middle-term (12-60 months), and long-term (>?60 months). Disease severity was assessed using endoscopy and computed tomography. Disease-specific QOL was measured with the 22-item Sinonasal Outcome Test (SNOT-22) and Rhinosinusitis Disability Index. Adjusted bivariate and multivariate associations between symptom duration, disease severity, and QOL scores were evaluated. RESULTS:One hundred and thirteen patients met inclusion criteria with 35 patients lost to postoperative follow-up. No significant differences in preoperative disease severity or QOL scores were reported between symptom duration subgroups. Participants in the long-term symptom subgroup reported significantly greater mean postoperative improvement on SNOT-22 total scores (n?=?28; -36.3[±?22.2]) compared to both short-term (n?=?27; -23.4[SD?±?11.3]; P?=?0.039) and middle-term (n?=?23; -23.5[SD?±?20.1]; P?=?0.050) subgroups. Postoperative QOL improvements in the long-term symptom subgroup remained significantly greater (P???0.036) after multivariate adjustment. CONCLUSIONS:Symptom duration was not associated with mean preoperative disease severity or QOL. Patients with long-term symptom duration reported the greatest mean postoperative QOL improvement, suggesting that delayed surgical intervention may not reduce QOL improvements following ESS.

Project description:Patient-reported measures are designed to detect a true change in outcome, but they are also subject to change from biases inherent to self-reporting: changing internal standards, changing priorities, and changing interpretations of a given instrument. These biases are collectively known as "response shifts" and can obscure true change after medical interventions.To determine the presence of response shifts in patients with chronic rhinosinusitis (CRS) after endoscopic sinus surgery.Multisite, prospective, observational cohort study conducted at academic tertiary care centers between February 2011 and May 2013. Study participants comprised a population-based sample of 514 adults (age ?18 years) with CRS, who elected surgical intervention for continuing medically refractory symptoms.Endoscopic sinus surgery.Preoperative and postoperative data from the 22-item Sinonasal Outcome Test (SNOT-22) survey instrument was characterized using exploratory factor analysis. Subsequent longitudinal structural equation models were estimated to test structure, potential response shifts, and true change in the SNOT-22 scores.A total of 339 participants (66.0%) provided survey evaluations at baseline and 6-month follow-up. Factor analysis of the SNOT-22 revealed 5 correlated, yet distinguishable, underlying factors. Endoscopic sinus surgery had a differential impact across these factors, with the largest effect size in rhinologic symptoms (mean [SD] SNOT-22 scores before and after surgery, 13.18 [5.11] and 7.37 [5.48], respectively; d?=?-1.13 [P?<?.001]) and extranasal rhinologic symptoms (8.31 [3.46] and 4.83 [3.68], respectively; d?=?-1.00 [P?<?.05]) (d is an effect size measure defined as the difference in means divided by the presurgery SD). Endoscopic sinus surgery had a smaller, yet significant, effect size on the remaining 3 factors: ear/facial symptoms (7.32 [4.6]) and 3.90 [4.07], respectively; d?=?-0.74 [P?<?.001]), psychological dysfunction (11.90 [7.21] and 6.50 [6.69], respectively; d?=?-0.75 [P?<?.05]), and sleep dysfunction (10.12 [5.59] and 5.88 [5.37], respectively; d?=?-0.76 [P?<?.001]). Participants were found to undergo recalibration, reprioritization, and reconceptualization of symptoms after intervention; however, the magnitude of these response shifts was small and not clinically significant.The SNOT-22 measures 5 distinct factors, not a single construct. Reporting of individual subscale scores may improve sensitivity of this instrument in future studies. Participants undergoing endoscopic sinus surgery experience only clinically insignificant response shifts, validating assessment of change through use of presurgery and postsurgery SNOT-22 responses.clinicaltrials.gov Identifier: NCT01332136.
