Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

807
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...

Tracheostomy Suctioning II: Procedure

3.0K
Tracheostomy suctioning is a vital nursing procedure that involves removing secretions from the tracheostomy tube to maintain airway patency and prevent respiratory complications. Nurses need to understand the proper technique for tracheostomy suctioning to ensure patient safety and comfort. In this guide, we will outline the step-by-step process for performing tracheostomy suctioning, including preparing the sterile field, donning personal protective equipment (PPE), lubricating and connecting...

Tracheostomy Care II: Procedure

2.4K
Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.
Step 1: Perform hand hygiene, and put on personal protective equipment: gown, gloves, mask...

Summary
This summary is machine-generated.

Transoral coronoidectomy effectively treats limited mouth opening caused by Langenbeck or Jacob disease. This surgical approach, combined with physiotherapy, significantly improves mouth opening and is a safe alternative to extra-oral procedures.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Skeletal Biology
  • Surgical Techniques

Context:

  • Limited mouth opening is frequently caused by coronoid process hypertrophy (Langenbeck disease).
  • Jacob disease involves coronoid process hypertrophy with osteochondroma or coronoid-malar bone conflict.
  • Coronoidectomy is the standard treatment for both conditions.

Purpose:

  • To describe and illustrate the transoral coronoidectomy technique for Langenbeck and Jacob diseases.
  • To evaluate the efficacy and safety of the transoral approach.
  • To emphasize the importance of post-operative physiotherapy.

Summary:

  • A transoral approach was used for coronoidectomy, involving subperiosteal dissection, burr severance at the base, and removal of the coronoid process.
  • Mouth opening improved intraoperatively, with further gains observed post-surgery.
  • The procedure was followed by immediate and long-term active physiotherapy.

Impact:

  • Transoral coronoidectomy is a simple, quick, and safe procedure with a lower risk of facial nerve injury compared to extra-oral approaches.
  • Significant improvements in mouth opening were achieved, from 24 mm to 36-40 mm (bilateral) and 22 mm to 38-43 mm (unilateral).
  • Long-term post-operative physiotherapy is crucial for sustained functional recovery and optimal mouth opening outcomes.
