Patients usually present with a slowly enlarging asymptomatic swelling. Diagnosis is usually made in the early stages because of the esthetic effects. Histologically, the lesion is lined with non-keratinized squamous epithelium or, more frequently, pseudostratified columnar epithelium with goblet cells. These cysts are most often diagnosed in the fourth decade of life. However, we report a case of nasolabial cyst in an 80-year-old woman, and discuss the diagnosis, differential diagnosis, and treatment with reference to the literature.展开更多

Hypoglossal schwannomas usually occur between the third and fifth decades of life, with no sex predilection, commonly presenting as a painless, slow-growing, and lateral neck mass. The best treatment is complete surgical excision with preservation of the neural pathway, if possible. In fact, since these tumors are almost always benign, a conservative surgical approach is emphasized by most authors. We report a case of a large schwannoma of hypoglossal nerve origin in the upper neck in a 31-year-old male. Magnetic resonance imaging of the area demonstrated a 43 × 39 × 36 mm well-circumscribed mass with high and nonhomogeneous signal intensity on the right side of the upper neck. The lesion was successfully treated by extirpation, with no recurrence. The extracranial hypoglossal nerve sheath was as the origin of this tumor because the patient experienced remarkable disturbance of tongue motility after surgery.展开更多

Abnormal airway anatomy may complicate the perioperative management of SGBS. However, there have been few reports regarding the anesthetic management of children with SGBS. We present the preoperative evalua-tion and intraoperative management of a 1.5-year-old child with SGBS undergoing plastic surgery for cleft palate. Sevoflurane-fentanyl anesthesia without a neuromuscular blocker was planned, due to the preoperative evaluation that airway management would be complicated by the macroglossia and short neck characteristic of SGBS. Fortunately, there was no difficulty in endotracheal intubation in the present patient due to careful planning of general anesthesia and meticulous airway management. Appropriate preoperative preparation for a difficult airway by the anesthe-siologist can ameliorate the difficulties inherent to the anesthetic management of patients with SGBS.展开更多
