Objectives: The gold standard treatments for advanced laryngotracheal stenosis (LTS) are represented by partial crico‐tracheal (PCTRA) or tracheal resection and anastomosis (TRA). These procedures are potentially burdened by high postoperative complication rates. We investigated the impact of the most common stenosis and patient‐related characteristics on the onset of complications in a multicentric cohort. Methods: We retrospectively analyzed patients who underwent PCTRA or TRA for LTS of different etiologies in three referral centers. We tested the effectiveness of these procedures, the impact of complications on the outcomes, and identified factors causing postoperative complications. Results: A total of 267 patients were included in the study (130 females; mean age, 51.46 ± 17.64 years). The overall decannulation rate was 96.4%. Altogether, 102 (38.2%) patients presented at least one complication, whereas 12 (4.5%) had two or more. The only independent predictor of post‐surgical complications was the presence of systemic comorbidities (p = 0.043). Patients experiencing complications needed additional surgery more frequently (70.1% vs. 29.9%, p < 0.001), and had a longer duration of hospitalization (20 ± 10.9 vs. 11.3 ± 4.1 days, p < 0.001). Six of 102 (5.9%) patients with complications had restenosis, although this event did not occur among patients without complications. Conclusion: PCTRA and TRA have an excellent success rate even when performed for high‐grade LTS. However, a significant percentage of patients may experience complications associated with a longer duration of hospitalization or the need for additional surgeries. The presence of medical comorbidities was independently related to an increased risk of complications. Level of evidence: 4 Laryngoscope, 133:2910–2919, 2023 [ABSTRACT FROM AUTHOR]

Objectives/Hypothesis: Laryngeal chondrosarcoma (LC) is a rare, slowly growing malignancy. The preferred treatment is laryngeal preservation surgery (LPS). Some patients may require multiple interventions or total laryngectomy (TL). We investigated risk factors for retreatment and TL, and assessed the impact of LPS on oncological and functional outcomes. Study Design: Case series Methods: We searched our institution database for LC. Tumor grading, localization, and margin status were tested as predictors of recurrence and organ preservation. Results: We included 21 patients (seven females, mean age 58 ± 12 years). LPS was applied in 20 (95.2%) of them as a primary procedure. Six patients were treated by transoral approach and 14 received "open‐neck" LPS. Fifteen (71.4%) were operated only once, while six patients underwent a total of 15 adjunctive procedures. Additional operations were always performed for recurrence of tumors localized within the cricoid plate. The histological grading was G1 in 81% and G2 in 19%. However, two patients with a primary G1 LC showed a G2 recurrence. Reoperations for recurrence were more frequent among patients with G2 in respect to G1 histology (83% vs. 7%, P <.001). Fifty percent of G2 LC and 8% of G1 underwent TL (P <.05). Margin status had no influence on recurrence rate. Conclusions: Patients with G2 LC have more recurrences requiring surgery and a higher incidence of TL. Cricoid plate localization is relevant for organ preservation. Margin status signals possible disease persistence, without influencing the need for future surgeries. Need for reoperation entails a risk of not being able to maintain organ functionality.

Objectives/hypothesis: Introduction and widespread use of cricotracheal resection and anastomosis (CTRA) as routine treatment for high-grade benign laryngotracheal stenosis (LTS) led to the need for a new classification system that could accurately predict surgical outcomes by integrating crucial stenosis and patient-related information. In 2015, the European Laryngological Society (ELS) proposed a new classification for benign LTS. We retrospectively tested it in adults treated at three referral centers to assess its reliability in predicting surgical outcomes.Study Design: Retrospective cohort study.Methods: We included 166 adults treated by open tracheal resection and anastomosis (TRA) and CTRA procedures, restaged according to the ELS classification evaluating grade of stenosis (I-IV, Myer-Cotton), number of subsites involved, and presence of systemic comorbidities. We correlated these parameters with decannulation, number of retreatments, and complications.Results: Final decannulation was predicted by a proposed ELS score ≥ IIIb, history of previous treatment, and length of resection (P < .05). Decannulation was achieved in 99% of patients without and in 88% of patients with surgical complications (P < .01). The incidence of surgical complications was related to the proposed ELS score (P < .01); an ELS score < IIIb showed a lower complication rate compared to patients with a ≥ IIIb score (32.8% vs. 57.7%, P < .01). Additional treatment was required in 73 (44%) patients (mean = 2.7 ± 2.2, range = 1-11). ELS score ≥ IIIb, length of resection, and occurrence of surgical complications predicted the number of such treatments (P < .05, P < .05, and P < .001, respectively).Conclusions: ELS classification of benign LTS is able to accurately predict success in adult TRA/CTRA procedures and may be helpful in choice of therapy and patient counseling.Level Of Evidence: 2b Laryngoscope, 130:1640-1645, 2020.

Objective: Idiopathic subglottic stenosis predominantly affects fertile and perimenopausal women. Estrogens and/or progesterone have been proposed as mediators of its pathogenesis by stimulating collagen deposition within the upper airway. We evaluated the presence and expression of estrogen-alpha (ER-α), estrogen-beta (ER-β), and progesterone receptors (PR) in idiopathic stenotic patients.Study Design: A retrospective analysis on 42 surgical specimens from idiopathic stenosis female patients (mean age, 52.4; age range, 31-79) and 28 gender- and age-matched controls.Methods: Immunoreactivity of ER-α, ER-β, and PR was calculated as the product of intensity (1 = weak, 2 = moderate, 3 = strong) and positive cell percentage (1-4, for < 10/10-50/50-80/ > 80%). This score was calculated on the stenotic and peristenotic tissues. Influence of menopausal status on hormonal expression and stenotic grade was tested.Results: Stenosis showed ER-α overexpression versus peristenotic tissue and controls (score 6.6 ± 4.4, 0.3 ± 0.5, and 2.2 ± 1.5, respectively; P < 0.001). Overexpression was even more marked for progesterone receptors (score 8.3 ± 3.6, 0.8 ± 0.6, and 1.0 ± 0.7, respectively; P < 0.001). There was no expression of ER-β in stenosis (score 0), whereas it was normally expressed in peristenotic tissue and controls (score 0.7 ± 0.5 and 0.5 ± 0.5; P < 0.001 vs. stenosis). Expression of ER-α was higher in postmenopausal stenotic patients (P < 0.01). This subgroup included a higher proportion of Cotton-Myer grade III stenosis than in premenopausal subjects (P < 0.001).Conclusion: An imbalance between ER-α, ER-β, and PR is present in idiopathic stenosis patients. The hormonal background may be involved in inappropriate inflammation and increased stenosis susceptibility. Menopausal changes seem to play a role in both stenosis grade and receptor patterns.Level Of Evidence: NA. Laryngoscope, 128:E72-E77, 2018. [ABSTRACT FROM AUTHOR]
