Rare but Real: Severe Unilateral Macroglossia and Submandibular Sialoadenitis After Skull Base Surgery.

We present a 43-year-old patient with a left-sided cerebellopontine angle meningioma with extension to the internal acoustic meatus and jugular foramen. The patient underwent a resection using a retrosigmoid approach, which resulted in near-complete tumor removal. Postoperatively, the patient experienced tongue swelling, swallowing difficulties and right-sided subcutaneous swelling, caused by patient positioning and endotracheal tube placement. Imaging showed phlegmonous infiltration of subcutaneous fat tissue with submandibular gland enlargement. The patient's condition gradually improved with conservative management. This case highlights the rare occurrence of combined macroglossia and sialoadenitis after posterior fossa surgery, emphasizing the importance of patient positioning and tube placement.
