Endoscopic CO 2 Laser Excision of Internal Pyolaryngocele: A Rare Airway Emergency Case Report With Review of the Literature

ABSTRACT A pyolaryngocele is a rare, potentially life‐threatening complication of laryngocele, resulting from secondary infection and obstruction of the saccular neck. Clinical severity ranges from mild dysphonia to acute airway compromise. We report a 51‐year‐old man with a sore throat, dysphagia, and dyspnea. Flexible laryngoscopy and contrast‐enhanced CT revealed an internal pyolaryngocele. After emergency tracheostomy and intravenous antibiotics, the patient underwent CO 2 laser microlaryngoscopic excision and marsupialization. Postoperative recovery was uneventful, with complete healing and no recurrence at follow‐up. This case underscores the importance of early diagnosis and highlights CO 2 laser surgery as an effective, minimally invasive option. Internal pyolaryngocele is a rare airway emergency that requires prompt management. CO 2 laser excision appears to be a safe and effective first‐line approach in selected internal cases.
