Summary
Brief summary (as posted)
This study retrospectively analyzed patients who underwent tracheal intubation under general anesthesia at the First Affiliated Hospital of Zhejiang University School of Medicine between October 1, 2015, and September 30, 2025, with a focus on issues related to postoperativelaryngopharyngeal complaints. Patients requiring otolaryngological consultation due to postoperative laryngopharyngeal complaints were identified via the case consultation system. Relevant patient data were collected through the Medison Anesthesia Information Management System and electronic medical record system, and telephone follow-up was conducted to assess patient prognosis. The primary outcome measures were the risk factors of postoperative hoarseness, while the secondary outcome measures included the incidence of postoperative hoarseness, the severity of vocal fold injury and its related risk factors. Additionally, the prognosis of patients and its related risk factors were evaluated. This study aims to reduce the incidence of perioperative laryngopharyngeal injury and provide a reference for the optimization of perioperative anesthetic regimens.

Arms and outcomes
Arms (1)
- label
- hoarseness
- description
- We collected perioperative clinical data from the cohort, analyzed the associated risk factors for the occurrence of relevant symptoms, and investigated the prognosis.
Primary outcomes (1)
- measure
- Postoperative hoarseness
- timeFrame
- Perioperative,up to150 days
- description
- The patients underwent general anesthesia with tracheal intubation and required otolaryngological consultation for hoarseness between October 1, 2015, and September 30, 2025.Hoarseness is characterized by alterations in voice quality, pitch (how high or low the voice is), volume (loudness), or vocal effort that impair effective communication, as judged by a healthcare provider, and may adversely affect quality of life.
Secondary outcomes (4)
- measure
- Incidence of Hoarseness
- timeFrame
- Perioperative,up to150 days

Inclusion Criteria: * Patients who underwent general anesthesia with tracheal intubation at the First Affiliated Hospital of Zhejiang University School of Medicine between October 2015 and September 2025 * Patients who required otolaryngological consultation due to laryngopharyngeal complaints (including hoarseness, sore throat, cough, choking on drinking water, etc.) postoperatively * The surgical type was non-otolaryngological surgery Exclusion Criteria: * Patients with a history of laryngopharyngeal lesions (e.g., granuloma, polyp, tumour, vocal cord paralysis * Patients with a preexisting tracheotomy * Patients requiring postoperative tracheotomy * Patients with incomplete medical records * Patients who underwent multiple surgeries but for whom the specific surgical episode responsible for the laryngopharyngeal complaints could not be identified
