Abstract

Objective: To evaluate the diagnostic performance of magnetic resonance (MR) with surface coils in assessing cartilage invasion in recurrent laryngeal carcinoma after carbon dioxide transoral laser microsurgery (CO₂ TOLMS).

Methods: Two expert head and neck radiologists assessed cartilage invasion (infiltrated or non-infiltrated) in submucosal recurrences of laryngeal carcinoma after CO₂ TOLMS: results were compared with histopathological report after salvage laryngectomy.

Results: Thirty patients met the inclusion criteria and 90 cartilages were assessed. Overall sensitivity, specificity, and positive and negative predictive values for cartilage infiltration were 76, 93, 72 and 94%, respectively; for thyroid cartilage, the values were 82, 79, 69 and 88% respectively; for cricoid cartilage, all values were 100%; and for arytenoids, the values were 33, 96, 56 and 93% respectively.

Conclusions: MR with surface coils was able to detect most thyroid and cricoid infiltration in the complex setting of post-CO₂ TOLMS laryngeal carcinoma recurrence. In particular, the optimal performance in assessing cricoid invasion can be valuable in choosing the most appropriate treatment among total laryngectomy, open partial horizontal laryngectomies and non-surgical strategies.

磁共振成像评估经口激光显微手术后喉癌软骨浸润。

目的:探讨表面线圈磁共振(MR)对喉复发癌经口激光显微手术(CO2 TOLMS)后软骨侵犯的诊断价值。方法:两名头颈放射科专家评估喉癌CO2 TOLMS术后粘膜下复发的软骨浸润(浸润性或非浸润性)，并将结果与喉切除术后的组织病理学报告进行比较。结果:30例患者符合纳入标准，评估了90个软骨。软骨浸润的总体敏感性、特异性和阳性、阴性预测值分别为76%、93%、72%和94%;甲状软骨分别为82%、79%、69%和88%;环状软骨均为100%;芳萜类化合物的回收率分别为33%、96%、56%和93%。结论:在复杂的co2后TOLMS喉癌复发情况下，表面线圈MR能检测到大多数甲状腺和环状膜浸润。特别是，评估环状侵犯的最佳性能可以在全喉切除术、部分水平喉切除术和非手术策略中选择最合适的治疗方法。

期刊介绍： Acta Otorhinolaryngologica Italica first appeared as “Annali di Laringologia Otologia e Faringologia” and was founded in 1901 by Giulio Masini. It is the official publication of the Italian Hospital Otology Association (A.O.O.I.) and, since 1976, also of the Società Italiana di Otorinolaringoiatria e Chirurgia Cervico-Facciale (S.I.O.Ch.C.-F.). The journal publishes original articles (clinical trials, cohort studies, case-control studies, cross-sectional surveys, and diagnostic test assessments) of interest in the field of otorhinolaryngology as well as clinical techniques and technology (a short report of unique or original methods for surgical techniques, medical management or new devices or technology), editorials (including editorial guests – special contribution) and letters to the Editor-in-Chief. Articles concerning science investigations and well prepared systematic reviews (including meta-analyses) on themes related to basic science, clinical otorhinolaryngology and head and neck surgery have high priority.
