Background: We have in a retrospective design used laryngotracheal stenosis (LTS) classification to describe stenotic subsites and through international classification of disease (ICD-10) codes its diagnostic origins. The diagnostic challenge posed by varied etiologies can lead to treatment delays, in potentially life-threatening conditions.

Aims/objectives: The purpose of this study is to explore and ascertain the etiological and anatomical distribution of LTS to reduce misdiagnosis and as such delayed access to adequate treatment.

Material and methods: The included cases were consecutively recruited between 1999 and 2019, all labeled with relevant ICD-10 codes for the research question in combination with medical records for evaluation of its accuracy. The primary outcome was the causes, and anatomical locations of LTS.

Results: A total of 1441 records were screened, with 1071 cases meeting the inclusion criteria. The most common cause was unilateral vocal fold immobility, followed by glottic cancer. Benign causes were more prevalent than malignant ones, with glottic-level stenoses being most frequent.

Conclusion and significance: Unilateral vocal fold immobility is the most prevalent cause of LTS in our material. These findings can enhance diagnostic efficiency by increasing clinical awareness of common etiologies.

Purpose: An accurate diagnosis and proper treatment plan are required to restore an adequate patent airway in fibrotic subglottic stenosis (SGS). Currently, the definitive treatment entails single-stage balloon dilatation with steroid injections. The primary aim was to evaluate successful airway restoration and general quality of life in cases with SGS in northern Sweden using robust patient reported outcomes.

Methods: All participants with need of surgical treatment due to SGS that had been referred to the department of otorhinolaryngology, University Hospital of Umeå from September 2020 to August 2023 was included. Exclusion criteria included malignant, extrathoracic or cartilaginous cause, age < 18 years, or incompetent to sign consent documents. We assessed the patient-reported outcome measures pre- as well as 3 months postoperatively.

Results: Of the 40 cases fulfilling the eligibility criteria’s, 33 cases completed the Dyspnea index (DI) and the short form health survey (SF-36) pre- as well as 3 months post-operatively. Receiver operating characteristics showed significant improvement in DI as well as in SF 36 scores post-operatively.

Conclusions: Evaluation of balloon dilatation in SGS in this cohort follow-up analysis shows clear improvement in patient quality of life using robust PROM 3 months postoperatively, ensuring the use of a safe and well-tolerated procedure.

Background: Subglottic stenosis (SGS) is a narrowing of the airway just below the vocal folds. The cause of SGS and the optimal care for these patients, have remained elusive. Endoscopic surgery of SGS using either balloon or CO2 laser is associated with recurrence.

Aims and objectives: Our aim is to compare surgery free intervals (SFI) between these two methods applied in two different timeframes. The knowledge gained from this project can support decision-making regarding surgical method choice.

Material and methods: Participants were retrospectively identified using medical records between 1999–2021. We used pre-defined broad inclusion criteria to identify cases using the International Classification of Disease (ICD-10). Primary outcome was surgery free intervals.

Results: 141 patients were identified, 63 met the criteria for SGS, and were included in the analysis. Results show no significant difference in SFI, comparing balloon dilatation and CO2 laser.

Conclusion: These findings demonstrate no detected difference in treatment intervals (SFI) when comparing these two commonly used surgical alternatives for SGS.

Significance: The outcome of this report supports surgical freedom of choice based on the surgeon’s experience and skill and ushes for further studies on patient experience regarding these two therapeutic approaches.
