Article Abstract
Background: Pyriform sinus fistula (PSF) is a rare congenital anomaly, and the preferred definitive treatment is yet to be verified. In this study, we investigated the treatment outcomes of PSF specifically comparing endoscopic-assisted surgery and endoscopic radiofrequency ablation (RA).
Methods: The medical records of patients treated for PSF at the Shanghai Children's Hospital between October 2016 and September 2019 were retrospectively evaluated.
Results: There were 93 girls and 98 boys. The median age at onset and operation was 3 years and 5 years, respectively. Endoscopic-assisted surgery was performed in 143 patients. During the same period, RA was performed in 48 patients, and 10 of them concurrently underwent incision and drainage of neck abscesses. Longer hospital stay was found in the endoscopic-assisted surgery group than in the RA group (10.50 ± 3.93 vs. 5.02 ± 3.30 days, P < 0.001). Postoperative complications were not significantly different between the two groups, except for neck infection (0 vs. 8.3%, P = 0.004). After a median follow-up period of 21 months, no significant difference was found between the two groups in terms of recurrence (1.4% vs. 0, P = 0.560).
Conclusion: Patients treated with RA had a significantly shorter hospital stay than those treated with endoscopic-assisted surgery. Outcomes of endoscopic-assisted surgery and RA were not significantly different for the management of PSF and treatment method should be tailored to the patient.
Level Of Evidence: IV.

[Transoral endoscopic-assisted submandibular gland resection with low-temperature plasma knife: clinical efficacy and literature review].

September 2025
To evaluate the feasibility and clinical efficacy of transoral endoscopic-assisted submandibular gland resection with low-temperature plasma knife technology, aiming to establish a scarless surgical approach to meet the patients aesthetic demands. A retrospective analysis was conducted on 5 consecutive patients with benign submandibular gland pathologies treated by a single surgical team between January 2021 and December 2023. All procedures employed a transoral mucosal incision in the floor of mouth, with 0-degree high-definition endoscope assistance and low-temperature plasma knife for precise dissection and hemostasis.

Background: Endoscopic-assisted transaxillary dual-plane augmentation mammaplasty is favored for its aesthetic advantages and minimal visible scarring. However, the optimal dissection tool between harmonic scalpel (HS) or monopolar electrotome (ME) remains debated due to limited comparative data.
Methods: A systematic review and meta-analysis were conducted by searching PubMed, Embase, and Cochrane Library for studies comparing HS and ME in endoscopic-assisted transaxillary dual-plane augmentation mammaplasty.
Lateral Molar Approach-Driven Transoral Endoscopic Procedure for Benign Infratemporal Fossa Tumor Resection.

Benign infratemporal fossa tumors necessitate complete resection while preserving neurovascular integrity. Conventional open approaches risk delayed bone healing, occlusal dysfunction, severe facial scarring, and iatrogenic neurovascular injury. We propose an endoscopic-assisted plasma ablation technique via a lateral molar transoral approach to address these limitations.

AUSS Assisted ACAF Technique in the Treatment of Ossification of the Posterior Longitudinal Ligament Extending to the C2 Segment.

Objective: This study aims to propose and evaluate the clinical efficacy of a novel non-coaxial endoscopic-assisted technique for establishing the "Shelter Space" in Anterior Controllable Antedisplacement and Fusion (ACAF) for treating high-level (C2-involved) cervical ossification of the posterior longitudinal ligament (COPLL).
Methods: Sixteen patients diagnosed with high-level OPLL (involving C2) who underwent AUSS (Arthroscopic-Assisted Uni-Portal Spinal Surgery) assisted ACAF treatment were enrolled, and their outcomes were analyzed. The OPLL below C2 was managed via ACAF, including discectomy at involved levels, appropriately removing the anterior part of the affected vertebrae below C2, placement of intervertebral cages, fixation with anterior cervical plates, and isolation of the vertebrae-OPLL complex (VOC).
