Đánh giá các yếu tố nguy cơ và ứng dụng thang điểm Laryngoscore trong dự báo khó khăn khi phẫu thuật nội soi thanh quản ống cứng

Abstract

Introduction: Multiple factors influence the degree of difficulty in laryngeal exposure during rigid laryngoscopic surgery. In 2024, Piazza et al developed the Laryngoscore to predict the level of difficulty based on various parameters. In Vietnam, there have been no studies addressing this issue. Subject and method: A prospective cross-sectional descriptive study was conducted on 68 patients undergoing rigid laryngoscopic surgery at the National Otorhinolaryngology Hospital from February 2025 to October 2025. Risk factors were assessed and analyzed using statistical algorithms with SPSS version 22.0. Result: Factors significantly associated with difficult laryngeal exposure during rigid laryngoscopic surgery (p<0.05) included: Male sex, age ≥ 45 years, neck circumference ≥ 33.5cm, prominent thyroid cartilage, macroglossia, BMI ≥ 23, and the need for increased tongue traction during indirect laryngoscopy (grade ≥ 2). The Laryngoscore demonstrated good predictive value with an AUC of 0.810; the optimal cutoff point was 4, yielding a sensitivity of 74% and specificity of 75%. Conclusion: The Laryngoscore is an effective tool for predicting the difficulty of laryngeal exposure in rigid laryngoscopic surgery.
