ABSTRACT
Traditional surgery to remove foreign bodies in the face carries a risk of postoperative morbidity with an injury to various anatomical structures, particularly the facial nerve and parotid duct and gland. Endoscopy can be a great aid in the removal of foreign bodies in the maxillofacial region. Surgical intervention using endoscope and/,or intraoperative images can be minimized, allowing the safe and precise removal of foreign bodies, and saving operating time. We report a case of the use of an endoscope and C-arm fluoroscopy guidance system to remove a very small foreign body.

Schwannomas are tumors which originate from the neuroectodermal Schwann cell of cranial, intraspinal, peripheral and autonomic nerve sheaths, and they are solitary, benign, slow growing and well encapsulated neoplasm. Schwannomas are usually asymptomatic. No strong gender or age predominance exists. The incidence of extracranial schwannomas in the head and the neck region varies from 25~45%. In addition, schwannomas are rare in the maxillary sinus or buccal space. In this paper, it diagnosed and treated a 54-years old female patient, who had schwannoma in the maxillary sinus derived from infraorbital nerves, the branch of the left trigeminal nerve, and a 19-years old male patient, who had schwannoma arose in the buccal space derived from the buccal branch of the right facial nerve. There was no particular complication except sensory extinction of the nerve in the female patient and paralysis by the nerve in the male patient. It is determined those two cases of schwannoma in the rare portion is valuable and herein, it reports those with literature discussions.
