Salivary Glands and Saliva01:23

Salivary Glands and Saliva

The salivary glands, of which there are three pairs known as the parotid, submandibular, and sublingual glands, play a crucial role in maintaining oral health and initiating the digestive process. Positioned near the ears, beneath the masseter muscle, the parotid glands secrete saliva into the oral cavity through the parotid duct of Stensen. Meanwhile, the submandibular glands, located on the floor of the mouth, secrete saliva through channels named submandibular ducts. The sublingual glands,...

Tracheostomy Suctioning II: Procedure

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...

Area of Science:

  • Interventional Radiology
  • Otolaryngology
  • Sialendoscopy

Background:

  • Salivary gland stones and strictures can cause significant discomfort and dysfunction.
  • Traditional treatments may be invasive or less effective for certain stone locations.

Purpose of the Study:

  • To evaluate the efficacy of interventional sialography for stone removal and stricture dilation.
  • To identify optimal techniques and limitations for percutaneous extraction and balloon dilation.

Main Methods:

  • Utilized short-tipped, wire-retrievable baskets for salivary stone extraction.
  • Employed percutaneous extraction for distal stones and guidewire/balloon systems for ductal strictures.
  • Described the use of access sheaths to facilitate stone retrieval.

Main Results:

  • Percutaneous extraction is effective for distal stones, but stones >20% duct diameter are challenging.
  • Intraglandular and proximal duct stones present significant removal difficulties.
  • Balloon dilation of strictures achieved 80-92% technical success.

Conclusions:

  • Interventional sialography offers a viable minimally invasive approach for managing salivary duct stones and strictures.
  • Careful patient selection and technique are crucial for successful percutaneous stone extraction.
  • Balloon dilation (siloplasty) demonstrates high efficacy for treating salivary duct strictures.
