Small cell carcinoma (SmCC) is a type of neuroendocrine tumor commonly originating in the lung, with only about 2-4% of cases arising at extrapulmonary sites. Extrapulmonary SmCC of the head and neck has a poor prognosis and a high rate of distant metastasis. The paranasal sinus is a rare location for extrapulmonary SmCC and only a few related papers have been published to date. We report a rare case of SmCC originating from the sphenoid sinus in a patient with a recurrent pituitary tumor with a literature review. [ABSTRACT FROM AUTHOR]

Background and Objectives: Endoscopic sinus surgery (ESS) has become the standard treatment modality in chronic rhinosinusitis. However there is no uniform treatment protocol regarding preoperative, intraoperative, and postoperative care. The objectives of this study are to identify and report the practice patterns of ESS in South Korea. Materials and Method: A series of eight surveys were sent to the board members of the Korean Rhinologic Society via email between August 2013 and September 2014. Responses to questions regarding detailed practice patterns were recorded anonymously. Results: The average number of replies to each survey was 41.5. Routine antibiotics were prescribed just before computed tomography by 46.9% of the respondents, and the mean duration of antibiotics treatment was 1.90 weeks. A routine preoperative olfactory test was conducted by 64.3% of respondents, and allergy tests were conducted by 82.2%. General anesthesia was preferred by 76.8%, and the mean hospitalization period was 3.12 days. The mean rotation speed used for a microdebrider was 3,054 rpm, and 3,000 rpm was selected by 51.6% of the respondents. In addition, 74.2% of respondents reported that they operate the foot switch themselves. Finally, an absorbable pack was preferred after ESS. Conclusion: The current study was the first nationwide survey on practice patterns in endoscopic sinus surgery in Korea, and the data reflects the opinions of expert sinus surgeons.

The basic principles of surgery for chronic rhinosinusitis are ventilation of the sinus ostia and conservation of the sinonasal mucosa. Since its introduction in 2006, balloon sinuplasty has been considered controversial by rhinologists. Balloon sinuplasty is a minimally invasive procedure for the treatment of chronic rhinosinusitis. However, some criticism has originated from the familiarity and preference many sinus surgeons have for conventional sinus surgery. Independent of this controversy, the current evidence supports the feasibility, safety, and efficacy of balloon sinuplasty. Furthermore, there has been increased interest in this procedure among physicians as well as patients. The objective of this review is to present and discuss the surgical technique, treatment outcomes and controversy associated with balloon sinuplasty. [ABSTRACT FROM AUTHOR]
