Postoperative nasal symptoms associated with an endoscopic endonasal transsphenoidal approach.

Summary of "Postoperative nasal symptoms associated with an endoscopic endonasal transsphenoidal approach."

Recent studies have indicated the usefulness of endoscopic endonasal transsphenoidal approach (EETSA). A few studies have reported on the postoperative nasal symptoms of patients who have undergone EETSA. Therefore, we adopted a rhinologic perspective to compare preoperative and postoperative nasal symptoms after performing a binostril, four-hand EETSA. Patients who were scheduled to undergo binostril, four-hand EETSA underwent preoperative nasal evaluation using the Nasal Obstruction Symptom Evaluation (NOSE), Sino-Nasal Outcome Test-20 (SNOT-20), and a visual analogue scale (VAS) to assess several nasal symptoms. Repeat testing was performed 6 months postoperatively. Paired Student's t tests were used to compare preoperative and postoperative scores. A total of 142 patients who underwent a binostril, four-hand EETSA were included in this study. We found no statistically significant differences between preoperative and postoperative NOSE, total SNOT-20 scores, or scores on the VAS for nasal obstruction, sneezing, rhinorrhea, snoring, or facial pain. However, VAS of olfactory change increased significantly after EETSA (p < 0.05). The binostril, four-hand EETSA would be a useful method because it permits operative manipulability and a wide visual field for skull base lesions. However, rhinologists must consider postoperative nasal symptoms and perform a proper preoperative examination, especially with regard to the olfactory function, and inform patients scheduled for EETSA of potential postoperative changes.

Abdominal symptoms after removal of the GALLBLADDER. The common postoperative symptoms are often the same as those present before the operation, such as COLIC, bloating, NAUSEA, and VOMITING. There is pain on palpation of the right upper quadrant and sometimes JAUNDICE. The term is often used, inaccurately, to describe such postoperative symptoms not due to gallbladder removal.
