Foreign body sensation is a nonspecific symptom of aerodigestrive tract diseases. Symptoms may be the result of gastroesophagealreflux, esophageal motility disorder, psychological factor and malignant lesion. Rarely, a unilateral bulging of the hypopharynx asa result of medial displaced superior cornu of the thyroid cartilage can be a reason. The appropriate diagnosis is made by fiberopticlaryngoscopy and CT scanning. Surgical removal of the portion of the superior cornu bulging toward the hypopharynx improvesthe foreign body sensation. We experienced two cases of medially displaced superior cornu of the thyroid cartilage without laryngealinjury. This unusual presentation is discussed with a review of the literature.

Company's growth is the development(or growth) of the connected industry and is closely affected by its development. The lower the entrance barrier of the relevant industry is , the easier this phenomenon comes. Because the change and the evolution is more speedy in the related industry, and the rivalry between the companies deepens rapidly, the industry that the entrance barrier is low has to change continuously for survival with its company's growth policy. In this article, with considered the natural-history paradigm on the development of the online transaction environment that has already been made a research, we divide the development stage of the internet business company and study the impulsive method with its result.

Isolated sphenoid sinusitis is a rare disorder. There are some difficulties in its diagnosis; therefore the first presentation of this disorder might be with complications. These complications are essentially due to the anatomical location of the sinus and its proximity to the intra-cranial and orbital contents, to which infection may easily spread. A case of isolated sphenoid fungal sinusitis with unilateral abducent nerve palsy is being reported which was successfully treated by parenteral antibiotic therapy and endonasal endoscopic sphenoidotomy.

Background and Objectives:This study investigates the effect of patient controlled analgesia (PCA) on post-tonsillectomy pain for the first two weeks of operation, and its effects on the postoperative bleeding and the pain duration. Subjects and Method:In a prospective group study, 43 patients with tonsillectomy were studied. PCA was applied for 48 hours after surgery. Pain scores, postoperative bleeding, and pain duration were compared. Results:PCA reduced postoperative pain during the time it was appled but pain was worse after disconnection. There were no differences between the groups regarding postoperative bleeding and recovery time. Conclusion:PCA could effectively control the post-tonsillectomy pain only during its application period. It was not helpful for long term pain control, pain duration, or post-tonsillectomy bleeding. Other long lasting and effective pain control method should be administered to reduce post-tonsillectomy pain during the recovery period.
