Postoperative vertigo after tympanomastoidectomy can be attributed to several causes such as inner ear damage due to excessive ossicle handling, labyrinthitis, BPPV resulting from vibration of drilling, iatrogenic lateral semicircular canal damage, and perilymphtic fistula. Differential diagnosis is critical for the proper management and prognosis of accompanied sensorineural hearing loss, but it may be difficult in some cases. Especially it is quite difficult to distinguish between the serous and suppurative labyrinthitis. In this article we present a case with simultaneous serous labyrinthitis and BPPV. The patient developed whirling vertigo and hearing loss on the 5th day after tympanomastoidectomy. After conservative treatment with steroid and antibiotics, his hearing recovered to preoperative level. We retrospectively reviewed the pitfalls to make a correct diagnosis in this patient and the serial change in nystagmus during the treatment period. The usefullness of the rotation chair test to predict the prognosis of sensorineural hearing loss in labyrinthitis was also discussed.

In today's international society, growth and prosperity of a company can be achieved by enhancing international competitiveness. Evaluation technique for international competitiveness between companies is an important part of the methodology for enhancing international competitiveness within a company. Since it is not reasonable to evaluate the entire entity of competitiveness by considering only few aspects of the company, techniques must be developed for competitiveness evaluation by simultaneously considering many aspects of the company. In this article, two such techniques are presented. One select representative competitiveness indices, and the other evaluates competitiveness by utilizing the ranking method.

Neurofibroma arises in the Schwann cells or in the peripheral tissue of nerve sheaths. It usually occurs as a part of neurofibromatosis and occasionally as a solitary lesion, but rarely occurs in the nasal cavity or in the paranasal sinuses. Organized hematoma is a rare solitary benign lesion with locally destructive behavior. It can be formed by the organizing process of hematoma in the unaerated environment. Organized hematoma by intratumoral bleeding has not yet been reported in the sinonasal tract. We recently experienced a case of neurofibroma accompanied by an organized hematoma extending into the maxillary sinus. It was treated successfully by a combination of endoscopic and Caldwell-Luc approach. It was finally confirmed as a neurofibroma containing an organized hematoma by histological and immunohistochemical examinations. Therefore, we present this rare case with a review of the literature.
