Objective: To explore the feasibility of laryngeal function preservation in surgical treatment of hypopharyngeal carcinoma with restrained vocal cord motility.
Methods: Twenty-six cases of hypopharyngeal carcinoma treated with conservative hypopharyngectomy were retrospectively analyzed. Partial resection of pyriform sinus and partial laryngectomy were performed. Suturing the remaining hypopharyngeal mucosa was used to cove the wound of hypopharynx in 5 cases, epiglottis complex flap in 21 cases. All patients received postoperative radiotherapy.
Results: The overall 3- and 5-year survival rates were 61.4% and 50.8% respectively. 76.9% (20/26) patients have laryngeal functions (voice, respiration and deglutition) completely restored and 23.1% (6/26) partially restored (voice and deglutition).
Conclusions: To improve the quality of life of the cases, the preservative surgery is feasible for the selected hypopharyngeal carcinoma cases with restrained vocal cord motility.

Background: We here investigated the value of imaging examination in evaluating tumor remission-based surgery in patients with head and neck squamous cell carcinoma (HNSCC), who had undergone neoadjuvant immunotherapy combined with chemotherapy (NICC).
Methods: HNSCC patients who underwent NICC and surgery from May 2021 to September 2023 were retrospectively analyzed. All patients had to undergo imaging examination evaluation, including enhanced computed tomography (CT) and enhanced magnetic resonance (MR) imaging before and after NICC.

To investigate the changes in the narrow band imaging (NBI) phenotypes of oropharyngeal, hypopharyngeal, and laryngeal squamous cell carcinoma after neoadjuvant immunochemotherapy, and to explore the clinical value of NBI endoscopy in re-evaluation and follow-up of pharyngeal and laryngeal squamous cell carcinoma after neoadjuvant immunochemotherapy. Twenty-nine patients diagnosed with locally advanced pharyngeal or laryngeal squamous cell carcinoma in the First Affiliated Hospital of Xiamen University from November 2021 to January 2024 and receiving 2 cycles of neoadjuvant immunochemotherapy were selected, including 26 males and 3 females, aged 43-80 years. Regular NBI and white light (WL) endoscopy examinations, as well as imaging examinations such as CT scans, were performed.

Objective: To assess the efficacy of computed tomography (CT)-based radiomics nomogram in predicting perineural invasion (PNI) in patients with hypopharyngeal squamous cell carcinoma (HPSCC).
Materials And Methods: Overall, 146 patients were retrospectively recruited and divided into training and test cohorts at a 7:3 ratio. Radiomics features were extracted and delta and absolute delta radiomics features were calculated.

Tracheal adenoid cystic carcinoma is a rare malignancy. We report the case of a 65-year-old male who presented to our department due to a 3-month history of mild dysphagia without other associated symptoms. The neck, laryngeal, and hypopharyngeal examinations were normal.
