Results  Onodi cells were identified in 86 (42.8%) out of 201 patients. A subgroup analysis revealed that Onodi cells were present in 45 (43.3%) female and 41 (42.3%) male patients. The position of the Onodi cells was superior with respect to the sphenoid sinus in 43 (50%) of the patients, superolateral in 36 (41.9%), and lateral to the sphenoid sinus in 7 (8.1%) of the patients. Conclusion  The present study indicated a high prevalence of Onodi cells, with approximately equal distribution among males and females, and mostly superior in position in relation to the sphenoid sinus.Introduction  Historically, concerns about complications following parathyroid surgery, such as airway compromise, bleeding and hypocalcemia, have precluded its consideration as a short-stay surgical procedure. Recent advancements in perioperative care have resulted in several publications demonstrating that parathyroidectomy can be safely performed as a short-stay procedure. Objectives  The aim of the present study was to describe the process of implementing a short-stay protocol focusing on preoperative patient education and postoperative calcium management for those undergoing surgery for primary hyperparathyroidism (PHP). Method  A retrospective audit of consecutive parathyroidectomies performed for PHP over the period between 2010 and 2013 was performed. A short-stay protocol (SSP) was introduced focusing on postoperative calcium management. Results were reaudited over the period between 2013 and 2015. Results  Consecutive parathyroidectomies in 76 patients were included in the study. A total of 42 patieent without adversely affecting outcomes.Introduction  Vitamin D is known to have immunomodulatory functions and has action on chronic inflammatory processes, such as nasal polyposis. Objective  The present study assessed the levels of 25-hy
