Application of modified pedicled nasal septum mucosa flap on cerebrospinal fluid leakage in transsphenoidal pituitary surgery / 中国医师进修杂志

ABSTRACT

explore the therapeutic effect of modified pedicled nasal septum mucosa flap on cerebrospinal fluid leakage in transsphenoidal pituitary surgery. Methods The clinical data of 28 patients treated with modified pedicled nasal septal mucosa flap during endoscopic transsphenoidal resection of pituitary adenoma in Dalian Central Hospital from August 2017 to December 2018 were analyzed retrospectively. Seven cases of high-flow cerebrospinal fluid leakage occurred during the operation. Skull base reconstruction was performed with modified pedicled nasal septum mucosal flap. Modified pedicled nasal septum mucosal flap was repositioned in 21 cases. Results Seven cases of modified pedicled nasal septum mucosal flap for skull base reconstruction had no postoperative cerebrospinal fluid leakage and 1 case had hypoolusia. Postoperative cerebrospinal fluid leakage occurred in One of the 21 patients with mucosal flap replacement, and stopped after 8 d of continuous lumbar drainage. One case had hypoolusia. Conclusions Modified pedicled nasal septum mucosal flap is a safe and reliable technique. It can not only achieve the effect of pedicled nasal septum mucosal flap in skull base reconstruction, but also avoid nasal complications caused by excessive application of mucosal flap.
