Obstructive sialadenitis is a common salivary gland disorder. This retrospective study evaluated the outcomes of sialendoscopy in 90 patients treated between July 2018 and December 2023.
OBJECTIVE:
To evaluate the success rate, complications, and predictors of treatment outcomes of sialendoscopy in patients with obstructive sialadenitis.
DESIGN:
Retrospective cohort study
SETTING:
Security Forces Hospital, Saudi Arabia
PATIENTS AND METHODS:
A retrospective cohort study was conducted using patient medical records. Patients with obstructive sialadenitis were included.
MAIN OUTCOME MEASURES:
Success of sialendoscopy, defined as complete endoscopic stone retrieval with confirmed ductal patency on post-retrieval irrigation. Four procedures in which no sialolith was identified intraoperatively were excluded from the stone-retrieval success denominator (n=94 stone-confirmed procedures).
SAMPLE SIZE:
Ninety patients
RESULTS:
Submandibular glands accounted for 74% (67/90) of cases. Success rates for complete stone retrieval were 79% (19/24 parotid) and 79% (55/70 submandibular). Key predictors of success included stone size, location, and number: stones >10 mm (OR=0.17, 95% CI: 0.04–0.67;
CONCLUSION:
In this one of the larger reported single-centre Saudi series, sialendoscopy demonstrated high success for obstructive sialadenitis, with stone size >10 mm, intraglandular location, and multiplicity as independent failure predictors. These findings support tailored approaches in Middle Eastern populations.
LIMITATIONS:
Retrospective single-center design, lack of long-term follow-up data, and absence of patient-reported outcome measures.
