External auditory canal cholesteatoma is an uncommon lesion of the external auditory canal, which usually present with otorrhea and chronic dull pain. It usually eroded bony portion of external auditory canal wall extensively with progressive bony lysis, and can extends into the middle ear cavity, tegmen tympani, mastoid air cells, and/or skull base. External auditory canal cholesteatoma invading skull base is rare, and such a case is not yet reported in Korea. We experienced one case of bilateral external auditory canal cholesteatoma invading the dura of middle cranial fossa which was treated surgically by the endoaural approach in right side and the middle cranial fossa /transmeatal combined approach in left side. We present this case with a review of the literature.

This study was performed to investigate the capability of preoperative evaluations in predicting the precise anatomic origin of intracanalicular tumors. We conducted a retrospective case review of 11 patients (8 male, 3 female; 26-70 yr of age) with intracanalicular tumors that were treated surgically. Data included preoperative pure tone audiogram, auditory brainstem response, caloric test, electroneurographies and temporal MRIs. Postoperatively, facial nerve schwannomas were diagnosed pathologically in two of 11 patients (18%). There were no clues suggesting facial nerve schwannoma in preoperative evaluations: A facial nerve schwannoma may be misdiagnosed as a vestibular schwannoma, especially when the tumor is confined to the internal auditory canal. There are no useful preoperative evaluation tools to predict precisely the origins of intracanalicular tumors. These emphasize the need to fully inform the patient preoperatively.

Liposarcoma is one of the most common malignancies originating from human soft tissue. Because most of liposarcoma occur in the lower extremities or retroperitoneum, there are few reports about liposarcoma of head and neck region, including larynx and pharynx. Histologically, there are four types of liposarcoma, and prognosis and recurrence rate are different according to histologic subtype. Wide excision is the treatment of choice and liposarcoma hardly respond to primary radiotherapy. A 56-year-old man presented with voice change and foreign body sensation in laryngopharynx. Hypopharyngeal liposarcoma was diagnosed by surgical biopsy and performed totallaryngopharyngoesophagectomy and gastric pull-up. Here we report our experience on this case with review of literature.

Objectives : In this study, we classified the anatomical correlation of the facial nerve, vestibular nerve, and cochlear nerve along different locations of the internal auditory canal and analyzed the clinical outcome of hearing preservation surgery of vestibular schwannoma through the middle cranial fossa approach performed based on the anatomical study results. Methods : Cadaveric temporal bone dissection of 58 Koreans was performed and each nerve distribution pattern along the segment from the brainstem to the base of internal auditory canal was classified and schematized. Clinical application results were obtained from medical records of 14 patients who were diagnosed of tumor originating from the internal auditory canal and received mass excision via extended middle cranial fossa approach. Results : The cochlear nerve and vestibular nerve could be separated at porus of the internal auditory canal in only about 6% of our materials, but we could identify the facial nerve, vestibular nerve complex and cochlear nerve individually at the midportion in about 88%. Hearing preservation, which was achieved in 10 of 14 patients was more feasible when the tumor was of superior vestibular nerve origin with medial location in the internal auditory canal and when the patient had better preoperative hearing. Conclusion : Applying the above mentioned topographic anatomical information to the extended midcranial fossa approach, the vestibular nerve and the cochlear nerve could be separated by initiating the dissection at the mid-portion after exposing the internal auditory canal and consequently achieve favorable results of functional preservation including hearing.
