Ultrasonographic biometry in normal salivary glands
1Universitäts-Hals-Nasen-Ohren-Klinik, Essen, Germany.
Summary
This study provides the first detailed ultrasonic measurements for normal submandibular and parotid salivary glands. These normal salivary gland dimensions serve as a crucial reference for diagnosing various medical conditions.
Area of Science:
- Anatomical measurements
- Ultrasonography
- Salivary gland imaging
Background:
- Normal salivary gland dimensions are not well-documented.
- Accurate reference values are needed for clinical diagnosis.
Purpose of the Study:
- To ultrasonographically determine the standard sizes of submandibular and parotid salivary glands.
- To establish reference dimensions for healthy salivary glands.
Main Methods:
- Utilized ultrasonography on 50 healthy adult volunteers.
- Ensured volunteers were free from salivary gland diseases and within a healthy weight range.
- Measured specific dimensions of submandibular and parotid glands.
Main Results:
- Submandibular gland dimensions: anterior-posterior length (35 ± 5.7 mm), paramandibular extension (14.3 ± 5.7 mm), frontal scanning extension (33.7 ± 5.4 mm).
- Parotid gland dimensions: parallel to mandibular ramus (46.3 ± 7.7 mm), transverse axis (37.4 ± 5.6 mm).
- Parotid parenchyma extensions: 7.4 ± 1.7 mm lateral and 22.8 ± 3.6 mm dorsal to the mandible.
Conclusions:
- Established normative ultrasonographic dimensions for submandibular and parotid glands.
- These measurements provide essential reference data for clinical evaluation and disease diagnosis.
- Ultrasonography is a viable method for assessing salivary gland size in healthy individuals.
