Transsphenoidal pituitary surgery has evolved over the past several decades, because advances in technology have been the catalyst for minimally invasive surgeries. Less invasive approaches, such as the transnasal approach with endoscopic resection of tumor and the completely endoscopic .technique have less morbidity and a shorter hospital stay than traditional sublabial approaches. Continued follow-up is needed to confirm long-term benefits and similar recurrence rates.

Although endoscopic repair of SB defect remains largely successful, certain factors should alert the surgeon to the potential for failure of repair or need for secondary SB defect repair.

Lacrimal canaliculitis is an infection of the lacrimal duct system. The classic features of lacrimal canaliculitis are mild to severe swelling of the canaliculus, mucopurulent discharge from the punctum, and a red, pouting punctum. Canaliculotomy with systemic or topical antibiotics is the most appropriate treatment for this disorder.

The influence of irrigation on bone cutting was determined by measuring the biomechanical performance of a bone cutting saw during irrigation with various solutions. Solutions of 0.9% saline and 10, 20, and 30% poloxamer-188 were used as the irrigant. A 10% solution of poloxamer-188 was judged to be the superior irrigant because it successfully maintained bone temperature at a controlled level without interfering with the rate of bone removal.
