Abstract

Objective: Lingual abscesses are rare but potentially serious infections of the tongue, with limited data in the literature. This study aimed to compare clinical, radiological, and laboratory features of anterior and posterior lingual abscesses and evaluate the impact of drainage on outcomes.
Methods: This retrospective case series included 17 patients diagnosed with lingual abscess between February 2019 and March 2025. Patients were categorized based on anatomical localization (anterior vs. posterior). Demographic data, symptoms, laboratory values (WBC, CRP, etc.), CT findings, treatment modalities, and outcomes were analyzed. Subgroup comparisons were performed based on abscess location, drainage status, and presence of rim enhancement.
Results: Of the 17 patients, 10 had anterior and 7 had posterior abscesses. Posterior abscesses were larger in size and associated with significantly longer hospital stays (p = 0.004). Drainage was associated with significantly shorter hospitalization (p = 0.005) and greater reduction in WBC counts by day 5 (p = 0.046). Rim enhancement on CT was not significantly associated with clinical or laboratory outcomes. Streptococcus species were the most commonly isolated pathogens. No major complications or airway interventions were required.
Conclusion: Posterior lingual abscesses demonstrate a more severe clinical course compared to anterior ones. Surgical drainage is associated with improved inflammatory markers and faster clinical recovery. Rim enhancement alone may not reliably reflect disease severity. These findings support the importance of early diagnosis and individualized management based on anatomical location and clinical progression.
