Abstract
Objective
Sialocele that develops after parotid surgery often prolongs the treatment period
and stresses both the surgeon and patient. The extent of surgery and tumor size are
known to be associated with sialocele occurrence. We investigated the incidence of
post-parotidectomy sialocele and the associated risk factors, with a focus on tumor
size.
Methods
We retrospectively reviewed the medical records of 172 patients who underwent parotidectomy
between January 2013 and May 2020 at Haeundae Paik Hospital, Inje University of Korea.
We stratified patients into those with and without sialocele (fluid collection in
the operative bed). We compared clinical data, patient demographics, and surgical
details; we identified risk factors for sialocele development after parotid surgery.
Results
Seventeen patients were diagnosed with post-parotidectomy sialocele (9.88%; 17/172).
Univariate logistic regression revealed that the male sex, deep lobe tumor location,
and large tumor size were significantly associated with postoperative sialocele (p = 0.015,
0.009, and 0.016, respectively). We subjected these parameters to multivariate analyses;
the odds ratios were 3.70, 3.58, and 2.34, respectively. Receiver operating characteristic
curve analyses showed that a tumor size > 2.50 cm was the optimal cutoff in terms
of predicting post-parotidectomy sialocele.
Conclusion
Male sex, a tumor in the deep lobe, and large tumor size were strongly associated
with increased risk for sialocele after parotidectomy. Tumor size > 2.50 cm serves
as the cutoff identifying patients likely to experience sialocele after parotid surgery.
