Background:

Bilateral parotid enlargement presents a broad differential diagnosis.
Accurate diagnosis is crucial for effective patient management and resource allocation.

Purpose of the Study:

To categorize disease entities causing bilateral parotid enlargement.
To develop a question-based algorithm for improved diagnosis of bilateral parotid masses.

Main Methods:

A comprehensive PubMed search identified 818 studies on bilateral parotid masses.
68 relevant studies were reviewed, compiling 22 disease entities into etiological categories.
Data on incidence, history, and physical examination findings were systematically analyzed.

Main Results:

Key diagnostic factors include disease incidence, onset timing, nodularity, pain, and skin changes.
The developed algorithm effectively reduces the differential diagnosis from 28 to 7 or fewer possibilities.
The algorithm relies solely on initial patient history and physical examination data.

Conclusions:

Grouping diseases by specific history and physical findings significantly narrows the differential diagnosis.
A diagnostic algorithm based on initial clinical encounter data can expedite diagnosis.
This approach aids clinicians in selecting appropriate workup and treatment, avoiding unnecessary tests.
