BACKGROUND: Gland-sparing surgical procedures for managing obstructive sialadenitis have significantly reduced the rate of sialoadenectomies with associated morbidities and provided a better alternative for sialolithotomy while successfully restoring gland function.
PURPOSE: The study purpose was to evaluate the recovery of salivary gland function and the improvement in patient quality of life (QOL) following gland-sparing sialolithotomy in individuals with sialolithiasis obstructive sialadenitis (SOS).
STUDY DESIGN, SETTING, AND SAMPLE: This is a prospective cohort study comprising patients who presented with SOS at a tertiary referral center between January 2021 and February 2023. Patients were excluded if they had acute sialadenitis, a history of salivary gland excision, or radiographic signs of gland atrophy.
PREDICTOR VARIABLE: The predictor variable was the time of assessing therapeutic effect after sialolithotomy which was measured at 3, 6, and 12 months postoperatively.
MAIN OUTCOME VARIABLES: The outcome variable was the therapeutic effect on salivary gland function (primary outcome) as measured by sialometry and QOL (secondary outcome), measured using the Multidisciplinary Salivary Gland Society questionnaire.
COVARIATES: The covariates were age, sex, salivary stone characteristics (size, number, and location), gland affected, and surgical approach used. Data were collected and analyzed.
ANALYSES: The Mann-Whitney test was used to compare 2 categories of different covariates. The Friedman test was used to compare repeated measures across follow-up periods. Pairwise comparisons were performed with Bonferroni correction. The adjusted P values were calculated automatically using SPSS. Statistical significance was set at P < .05 for all tests.
RESULTS: The studied sample included 41 subjects (56.1% males) with mean age 37.88 ± 12.79 years. Primary outcome showed mean overall sialometry score improvement from 2.21 ± 1.02 g preoperatively to 3.42 ± 1.23 for submandibular and from 1.87 ± 1.48 g to 2.92 ± 1.28 for parotid at 12 months postoperatively (P < .001). Similarly, secondary outcome showed significant subjective improvement, from total Multidisciplinary Salivary Gland Society score 65.92 ± 28.63 to 3.84 ± 9.59 for submandibular and 72.42 ± 38.27 to 7.11 ± 12.13 for parotid (P < .001).
CONCLUSION AND RELEVANCE: Gland-sparing surgical procedures represent an excellent option for managing SOS. Successful sialolithotomy resulted in significant improvement in gland function, and QOL.
