[Chronic obstructive parotitis: a report of 92 cases]
1School of Stomatology, Beijing Medical University.
Summary
Chronic obstructive parotitis involves saliva flow obstruction causing recurrent parotid swelling. Sialography reveals duct dilation, with treatment varying by type, including surgery and methyl violet injection.
Area of Science:
- Otolaryngology
- Sialology
- Surgical Pathology
Background:
- Chronic obstructive parotitis is characterized by saliva flow obstruction leading to recurrent parotid gland swelling.
- Sialography is crucial for diagnosis, revealing irregular dilatation of parotid ducts, classifiable into four types.
Purpose of the Study:
- To present findings on 92 cases of chronic obstructive parotitis.
- To evaluate the efficacy of various treatment modalities, including conservative therapy, surgery, and 1% methyl violet injection.
Main Methods:
- Clinical examination
- Sialography
- Sequential quantitative scintigraphy
- Surgical intervention
- 1% methyl violet gland injection
Main Results:
- Sialographic findings were categorized into four types.
- Type I cases responded well to conservative treatment.
- Other types required alternative treatments like parotidectomy.
- 1% methyl violet injection proved effective for persistent swelling and post-parotidectomy purulent discharge.
Conclusions:
- Treatment for chronic obstructive parotitis should be tailored to sialographic findings.
- Conservative methods suffice for Type I, while other types necessitate surgical or interventional approaches.
- 1% methyl violet injection offers a safe and effective treatment option for specific complications.

01:26Methods of Documentation II: POMR
The Problem-Oriented Medical Record (POMR) revolutionized medical record-keeping by introducing a systematic approach focusing on the patient's problems rather than merely listing symptoms. Dr. Lawrence Weed's introduction of this method in the 1960s marked a significant advancement in medical documentation. The POMR framework consists of four key components: the database, problem list, plan of care, and progress notes.
01:24Chronic Obstructive Pulmonary Disease
COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

01:23Chronic Pharyngitis
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

01:20Chronic Obstructive Pulmonary Disease-I: Introduction
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.
01:23Chronic Obstructive Pulmonary Disease I: Introduction
Chronic obstructive pulmonary disease is a common, preventable, and treatable respiratory disorder characterized by persistent symptoms and progressive airflow limitation. This limitation results from a combination of small-airway disease (obstructive bronchiolitis) and parenchymal destruction (emphysema), both driven by chronic inflammation from exposure to harmful particles or gases.The disease includes two main pathological entities: emphysema, marked by destruction of alveolar walls and...
01:23Chronic Obstructive Pulmonary Disease II: Emphysema
Emphysema, a major phenotype of chronic obstructive pulmonary disease (COPD), is characterized by irreversible destruction of alveolar walls and permanent enlargement of distal airspaces. Unlike chronic bronchitis, which primarily affects the airways, emphysema predominantly involves the lung parenchyma, where structural damage leads to airflow limitation.PathophysiologyIt most commonly results from prolonged exposure to cigarette smoke and other toxic gases, particularly cigarette smoke.
