Summary
Patient-reported outcome measures (PROMs) for salivary gland dysfunction vary in validation. While some PROMs show good internal consistency, content validity is a limitation, necessitating patient and provider input for future tool development.
Area of Science:
- Otorhinolaryngology
- Health Outcomes Research
- Medical Informatics
Background:
- Numerous patient-reported outcome measures (PROMs) exist for salivary gland dysfunction, but their validation and scope vary.
- Assessing quality of life and symptom severity in patients with salivary gland dysfunction requires reliable and validated instruments.
Approach:
- A systematic review adhering to PRISMA guidelines was conducted.
- Databases searched included PubMed, Web of Science, Embase, PsycInfo, and CINAHL.
- PROMs with validated instruments assessing salivary gland symptoms were evaluated using COSMIN criteria for methodology, structure, validity, and reliability.
Key Points:
- Sixteen PROMs were identified for conditions including xerostomia, sialadenitis, Sjögren's syndrome, and Parkinson's-associated sialorrhea.
- Eleven PROMs demonstrated good internal consistency, and 10 included test-retest reliability data.
- Content validity was a limitation across all PROMs, with none rated as adequate despite some patient and physician input.
Conclusions:
- Existing PROMs for salivary gland function have variable design and validation standards.
- Significant limitations exist in the content validity of current PROMs.
- Future development of PROMs for obstructive and inflammatory salivary symptoms should prioritize patient and provider input.

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

01:23Salivary Glands and Saliva
818
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,...

Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
