Lingual Abscess: Predisposing Factors, Pathophysiology, Clinical Manifestations, Diagnosis, and Management

Lingual abscess is a rare disorder, and current knowledge regarding clinical manifestations and treatment modalities has not been well established. This study presented 6 cases of lingual abscess patients between January 2012 and December 2017. There were three men and three women. Median age was 54 years. Odynophagia and local pain were the common presenting symptoms. Local trauma was the main predisposing factor of anterior abscess, while lingual tonsillitis or infected thyroglossal cyst was the predisposing factor of posterior abscess. An impending airway obstruction was identified in two patients, requiring tracheostomy. All patients achieved an excellent outcome with a combination of surgical drainage and proper antibiotics as well as using proper investigation for detecting unusual areas of lingual abscess. According to the data from the study's results and review of the relevant literature, an abscess located at the anterior two-thirds of the tongue is easy to diagnose while the posterior one-third of the tongue abscess is relative difficulty. Using contrast-enhanced computed tomography increases diagnostic accuracy, especially on the tongue base and deep space infection. The management strategies include (1) protecting the airway, (2) draining the abscess by needle aspiration or surgery, and (3) administering antibiotics early. Our series showed a superiority of surgical drainage when the patients present with marked tissue edema, deep loculated infection, and airway obstruction.
