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

: 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 CO2 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 CO2 laser surgery as an effective, minimally invasive option. Internal pyolaryngocele is a rare airway emergency that requires prompt management. CO2 laser excision appears to be a safe and effective first-line approach in selected internal cases.
