Long-Term Outcome Analysis of Endoscopic Sinus Surgery for Chronic Sinusitis
Bibliographic record
Abstract
BACKGROUND: The purpose of this study was to determine long-term subjective outcome of endoscopic sinus surgery (ESS) for chronic sinusitis (CS) and to evaluate prognostic indicators for surgical treatment failure. METHODS: This is a prospective study of patients who underwent ESS for CS. Symptom assessment was performed using a visual analog scale at a pretreatment interview and then at regular intervals post-ESS for up to a 3-year period. The indicators for symptom scoring were nasal obstruction, facial pain, postnasal drip, anterior discharge, and anosmia/hyposmia. RESULTS: Data analysis indicates that ESS improves symptom scoring early on, but the effects begin to dissipate over time. Anosmia/hyposmia is the most severe symptom overall for all patient subgroups and recurs to a greater degree 3 years postoperatively in Samter's Triad sufferers (p = 0.006), asthmatic patients (p = 0.002), and those with a worse CT scan at presentation (p = 0.04). In addition, Triad sufferers who complain of nasal obstruction and anterior nasal discharge have a significant recurrence of their symptoms postoperatively (p = 0.04 and 0.001, respectively). CONCLUSION: Individuals must be warned that ESS may not be a long-term solution for CS because of its chronic nature. Patients are relieved of their symptoms initially; however, these tend to recur over a 3-year period. Samter's Triad is the strongest determinant of long-term treatment failure. Asthma also is a determinant of treatment failure, which lends credence to the notion of combined airway disease. Allergy was not a strong determinant of treatment failure in our study.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
