A Case of Treatment of Traumatic Recurrent Frontal Sinusitis with T-tube / 대한이비인후과학회지

The most common disease process involving the frontal sinus is infection secondary to inadequate drainage through the frontal recess. Obstruction of the frontal recess may result from rhinosinusitis, allergic rhinitis, nasal polyposis, tumor and traumatic injury. The principle treatments are not only ventilation and drainage but also removal of predisposing factors. If there is no response to conservative treatment, surgical treatment is considered. To prevent closure of the frontal recess, external approach, endoscopic approach, grafts, indwelling tubes and mucoperiosteal flaps have been used. Insertion of silicone tube in frontal recess is a simple and easy method of drainage through frontal recess. We report a case of traumatic recurrent frontal sinusitis which was treated by endoscopic sinus surgery with silicone T-tube insertion.

Schwannomas of the Sinonasal Tract: Three Case Reports

Schwannomas are benign tumors derived from the Schwann cells of the nerve sheath. These are rare tumors that can be found in any part of the body although fewer than 4% of these tumors involve the nasal cavity and paranasal sinuses. Here, we present three cases of sinonasal schwannoma. The tumor masses were removed by endoscopic excision under general anesthesia. Pathological examination of the excised specimens confirmed schwannoma and the tumor cells were immunoreactive for S-100 protein. The patients are doing well with no evidence of recurrence.
