Management of MACROGLOSSIA: Case Series and Suggested Algorithm

Abstract

Idiopathic macroglossia is a rare entity of true tongue enlargement without an underlying etiology. There are only a few case reports on the diagnosis and management of idiopathic macroglossia. This study's purpose was to present a series of patients with idiopathic macroglossia and suggest a treatment algorithm. This was a retrospective case series of a cohort of patients with macroglossia who were treated by the Oral and Maxillofacial Surgery service at the University of Texas Health Science Center at Houston (UTHealth)and Emory University. The patient's medical comorbidities, history of present illness, clinical presentation, radiographic findings, and disease management were studied. The outcome variables include normalization of the tongue size, dependence on parenteral nutrition, and tolerating tracheostomy decannulation. Five patients with a mean age of 45years were included in the study. All of the patients (n=5, 100%) in our cohort developed macroglossia following prolonged oral intubation, with 3.5weeks being the average length of intubation. All patients presented with difficulty feeding orally and breathing. The average tongue dimension was 12.20 x 6.25cm. All tongue enlargements were located in the anterior 2/3 of the tongue, and all patients had displaced anterior dentition. In addition, 60% of the patients (n=3) experienced altered tongue sensation (pain and/or decreased taste). These patients were surgically managed with tracheostomy and percutaneous endoscopic gastrostomy (PEG) tube placement followed by partial glossectomy (n=5, 100%). We defined successful outcomes as 1) modifying the tongue to a functional, nonprotruding form, 2) tracheostomy decannulation and 3) PEG tube removal. Tracheostomy decannulation and PEG tube removal were achieved in 80% of the patients (n=4). In this patient cohort, we were unable to identify the cause of the pathology based on existing clinical data. When the etiology is unclear or irreversible, management should involve tracheostomy and surgical feeding access for the initial stabilization, followed by modified glossectomy to improve form, function, and cosmesis thereby improving the overall quality of life.
