[Diplopia and blepharoptosis associated with orbital emphysema following thoracotomy with lung cancer; report of a case].

ABSTRACT

BACKGROUND: Orbital emphysema is a common complication of trauma and fracture of orbital bones. However, subcutaneous emphysema also can rarely lead to orbital emphysema. We reported the clinical and radiological findings in a patient with diplopia and blepharoptosis following thoracotomy for lung cancer. CASE A 76-year-old man had undergone left inferior lobectomy and ND 2 a in October 2002, based on the clinical diagnosis of stage IB lung squamous cell carcinoma. He presented with diplopia and blepharoptosis several days following thoracotomy. Chest X-ray demonstrated extensive subcutaneous emphysema, and physical examination also revealed diffuse subcutaneous emphysema including face and palpebrae. Head computed tomography (CT) revealed subcutaneous emphysema in the infratemporal fossa bilaterally. His diplopia and blepharoptosis gradually resolved, and he was discharged with no visual complaints on the fourteenth postoperative day. CONCLUSIONS: Subcutaneous emphysema can lead to diplopia and orbital emphysema in the absence of orbital trauma. Early surgical intervention for air leakage is highly recommended to avoid both the orbital emphysema and the visual complications in the event that subcutaneous emphysema should get to including face or palpebrae.
