후두 미세 수술 후 발생한 경부 피하기종 1예

Laryngomicrosurgery (LMS) has been commonly used for benign laryngeal lesion, especially in phonosurgery. LMS has relatively low incidence of complications. Some complications are related to the process of approaching laryngeal lesion, referred to as mechanical complication. Among these mechanical complications, cervical subcutaneous emphysema occurs rarely. Subcutaneous emphysema is the state of existence of gas or air in the layer under the skin. In most cases, it is self-limited, but it may sometimes extend to mediastinum and axilla. We present a case of cervical subcutaneous emphysema following laryngomicrosurgery in a 61-year old male who have the intracordal cyst. The day after surgery, we found right side cervical subcutaneous emphysema, and did conservative management. Two days after surgery, the symptom resolved and the patient was discharged from the hospital. We report this case regarding the diagnosis and treatment with review of literatures.
