Subcutaneous Emphysema Following Nasal Positive Airway Pressure Therapy in a Patient With a History of Tongue Base Tumor Resection

Positive airway pressure (PAP) therapy is chosen as the primary modality for most patients with obstructive sleep apnea due to its efficacy and safety. However, PAP therapy can cause potential side effects, including barotrauma, which in most cases is benign and manageable. Nevertheless, rare but serious complications, such as subcutaneous emphysema, may also occur. Here, I present a case of a middle-aged man with a history of tongue base tumor resection who developed subcutaneous emphysema in the neck following nasal PAP therapy. This case highlights the potential risk associated with previous surgical interventions and PAP therapy.
