Summary
Supratracheal partial laryngectomy (STPL) offers effective oncological and functional outcomes for intermediate/advanced laryngeal cancer with sub-glottic extension. This function-sparing surgery demonstrates good survival and organ preservation rates, particularly for earlier stages.
Area of Science:
- Otolaryngology
- Surgical Oncology
- Laryngeal Cancer Research
Background:
- Intermediate/advanced laryngeal cancer poses challenges for disease control and organ preservation.
- Supratracheal partial laryngectomy (STPL) is a function-sparing technique for laryngeal cancer with sub-glottic extension.
Purpose of the Study:
- To evaluate the indications, contraindications, and long-term oncological and functional outcomes of STPL.
- To analyze clinical results in patients with laryngeal cancer staged pT2-pT4a undergoing STPL.
Main Methods:
- Multi-institutional study analyzing clinical outcomes of 142 patients with laryngeal cancer (pT2-pT4a) who underwent STPL.
- Evaluation of five-year overall survival (OS), disease-specific survival (DSS), disease-free survival (DFS), loco-regional control (LRC), laryngeal function preservation (LFP), and laryngectomy-free survival (LFS).
Main Results:
- Five-year survival rates varied by stage: pT2 (OS 71.4%, DSS 95.2%), pT3 (OS 85.3%, DSS 91.1%), and pT4a (OS 73.2%, DSS 88.1%).
- DFS and LRC were significantly impacted by pT4a staging. LFP and LFS were affected by pT staging and age (≥65 years).
- Common sites of local failure included the tracheal passage, posterior commissure, contralateral cricoarytenoid unit, and outer larynx surface.
Conclusions:
- STPL is an effective surgical option for glottic or transglottic tumors with sub-glottic extension, offering favorable prognostic and functional results.
- Careful patient selection based on local and general factors is crucial for optimizing outcomes.
- STPL contributes to laryngeal function preservation and improved survival in selected laryngeal cancer patients.

01:30Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques
823
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

01:22Trachea
6.3K
The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of...

01:28Tracheostomy: Procedure and Tubes
5.2K
A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...

Endotracheal or ET intubation is a critical medical procedure used to secure a patient's airway, often in acute respiratory distress, apnea, upper airway obstruction, ineffective clearance of secretions, high risk for aspiration, or during general anesthesia.
The ET tube comprises various components, including a standard adaptor to attach a bag-valve-mask (BVM) or ventilator, a cuff, a pilot balloon, and radiopaque markings along its length to measure the insertion distance. The tube sizes...

A tracheostomy is a surgical technique that involves making an incision in the neck to provide access to the trachea. It is frequently used in medical conditions such as airway obstruction and prolonged mechanical ventilation. Effective nursing management is crucial for the long-term success of a tracheostomy.

2.7K
Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
