Summary
This study introduces an improved surgical environment for transoral minimally invasive surgery in oropharyngeal cancer patients. The new approach achieved excellent oncologic outcomes and functional results with no mortality.
Area of Science:
- Otolaryngology
- Surgical Oncology
- Minimally Invasive Surgery
Background:
- Transoral minimally invasive surgery for oropharyngeal cancer has limitations.
- Development of novel surgical environments is crucial for improving outcomes.
Purpose of the Study:
- To evaluate a new surgical environment for endoscopic transoral resection of oropharyngeal cancer.
- To assess the safety, efficacy, and functional outcomes of the novel approach.
Main Methods:
- 17 patients with oropharyngeal squamous cell carcinoma underwent endoscopic transoral resection.
- Utilized a pharyngeal retractor or distending laryngoscope, rigid videoendoscope, and laparoscopic instruments.
- Documented oncologic and functional outcomes, as well as complications.
Main Results:
- Achieved a 2-year relapse-free survival rate of 100%.
- Demonstrated satisfactory postoperative swallowing (94.1% scored ≤1 on FOSS) and speech function.
- Reported no perioperative mortality.
Conclusions:
- The enhanced surgical environment facilitates safe, reliable en bloc resection with improved visualization and working space.
- This system shows promise for oropharyngeal cancer treatment, warranting further investigation.
- Further studies are needed to validate these findings in a larger patient cohort.

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

01:25Suctioning the Oropharyngeal Airway
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...
