Microsurgical Resection of Pituitary Adenoma via Single-Nostril Transsphenoidal Approach

OBJECTIVE To explore the methods and experience of thesingle-nostril transsphenoidal approach for treating pituitaryadenomas.METHODS We retrospectively analyzed 46 patients whohad pituitary tumors and received surgery via the singlenostriltranssphenoidal approach and observed the effects andcomplications of surgery. The specific surgical methods are: a nasalspeculum is inserted slowly through the right nostril towards theanterior wall of the sphenoid sinus. A 1.5 cm incision is made intothe nasal mucosa in the right nasal cavity at the level of the middlenasal turbinate. By fracturing the bony septum, a space is formedbetween the bilateral nasal mucosa and the bony septum of thesphenoid sinus. Then, the inside of the sphenoid sinus is exposed.The remaining part of the bony septum, the anterior sphenoidsinus wall, and the sphenoid mucosa are gradually removed. Theanterior sphenoidotomy is less than 1.5 cm wide. After confirmingthe tumor by dural puncture, a cross incision of the dura is made,and the tumor is slowly removed by curette. The sella is usuallycollapsed and visible after the total tumor removal. When thetumor is resected satisfactorily, gelatin sponges are placed into theoperative cavity to stop bleeding.RESULTS Postoperative MRI scans revealed that among the 46cases, total resection of the tumor was achieved in 34 cases andsubtotal in 12. No deaths or disability occurred, and the hormonelevels of almost all patients improved. Signs of diabetes insipidusoccurred in 17, electrolyte disturbances in 5, and there were noreports of postoperative cerebrospinal fluid rhinorrhea.CONCLUSION The direct single nostril transsphenoidalapproach of continuous improvement has the advantages ofa convenient approach, simplified operation, safety and highefficiency.

Neuroendoscopic and microscopic transsphenoidal approach for resection of nonfunctional pituitary adenomas

BACKGROUND Nonfunctional pituitary adenoma is a common type of pituitary adenoma, which can lead to headache, visual field disturbance, and cranial nerve damage due to increased tumor volume. Neuroendoscopic and microscopic transsphenoidal approaches have been widely used in the resection of nonfunctional pituitary adenomas. However, the clinical efficacy in neuroendoscopic and microscopic surgery is still controversial. AIM To explore the clinical efficacy of neuroendoscopic and microscopic transsphenoidal approach for resection of nonfunctional pituitary adenomas. METHODS We retrospectively analyzed 251 patients with nonfunctional pituitary adenomas;138 underwent neuroendoscopic surgery via transsphenoidal approach, and 113 underwent microscopic surgery via transsphenoidal approach between July 2010 and September 2015. All patients were followed up for > 6 mo. Gender, age, course of disease, tumor diameter, tumor location, and percentage of patients with headache, visual impairment, sexual dysfunction, and menstrual disorders were contrasted between the two groups to compare the difference of preoperative data. Cure rate, symptom improvement rate, recurrence rate, the postoperative hospital stay, operating time, intraoperative blood loss, and the incidence of postoperative complications were compared in order to evaluate the advantages and disadvantages of neuroendoscopic and microscopic surgery.RESULTS There was no significant difference in cure rate, symptom improvement rate, and recurrence rate between neuroendoscopy group and microscopy group (82.6% vs 85.8%, P > 0.05;90.6% vs 93.8%, P > 0.05;5.1% vs 9.7%, P > 0.05). In the neuroendoscopy group, the postoperative hospital stay was 8.4 ± 0.6 d;operating time was 167.2 ± 9.6 min;intraoperative blood loss was 83.4 ± 9.3 mL, and the rates of diabetes insipidus and electrolyte imbalance were 4.3% and 8.0%, respectively. The corresponding results in the microscopic group were 11.2 ± 0.6 d, 199.7 ± 9.3 min, 138.8 ± 13.6 mL, and 32.7% and 20.4%, respectively. There were significant differences in postoperative hospital stay, operating time, intraoperative blood loss, and the rates of diabetes insipidus and electrolyte imbalance between the two groups (P < 0.05). CONCLUSION Neuroendoscopic and microscopic transsphenoidal approaches have similar clinical efficacy for the resection of nonfunctional pituitary adenomas. Neuroendoscopic surgery reduces operating time, intraoperative bleeding, postoperative recovery, and complications.

Trans-nasosphenoid pituitary adenoma microsurgery in 100 cases

The rhinologist participating in microsurgery of the pituitary adenomaplays an important role in relieving the patients from suffering and indecreasing the incidence of complications.This paper summarily reportsrhinological aspects in 100 cases undergoing trans-nasosphenoid intrasellarmicrosurgery,including operative routes and incisions,methods for opening andreconstructing the sellar floor and nasal comPlications.The authors suggest aseptavestibular incision to modify Hirsch’s septal incision,and outline our fivemethods to open and reconstruct the sellar floor.The operator should select themost proper method according to different situations,in operation.The most dan-gerous complications are CSF rhinorrhea with supurative meningitis and fatalhemorrhage.In our experience five such cases were cured by medical and surgicaltreatments.

The Use of Neuronavigation with Vasular Microdoppler in Transsphenoidal Pituitary Surgery

Object: To evaluate the use of neuronavigation with vascular micro-doppler in transsphenoidal pituitary surgery. Methods: 141 cases having done transsphenoidal pituitary surgery are evaluated from 2005 to 2014. Fluoroscopy was used in 69 cases and vascular micro-doppler with neuronavigation were used in 72 cases. Results: Transsphenoidal surgery has a lot of risks due to sella’s deep location, and position of the carotid artery and the optic nerve. Clasically the fluoroscopy and microscopic anatomical markers were used in order to minimize the risk of carotid artery and optic nerve damage. Additional devices such as neuronavigation and vascular micro-doppler are needed to decrease the morbidity and mortality arising from these injuries. Conclusion: Neurovascular complications such as carotid artery and optic nerve injuries owing to disorientation in transsphenoidal surgery will reduce the use of neuronavigation with vascular micro-doppler.

Transsphenoidal approach to pituitary adenoma： surgical technique of the Peking Union Medical College Hospital

The transsphenoidal approach to pituitary adenoma is still a non-universal approach used in different centers of different areas in our country. The transsphenoidal approach has a number of variations, including the endonasal rhinoseptoplastic, transnasal displacement,

Transsphenoidal microsurgical operation for pituitary adenomas with suprasellar extensions

Objective: To evaluate the feasibility and therapeutic effectiveness of the transsphenoidal microsurgical removal of pituitary adenomas with suprasellar extensions. MethodS: We reviewed the diagnosticmodes, surgical technique, and outcomes of 152 patients suffering from pituitary adenomas with suprasellarextensions who were treated by transsphenoidal microsurgery in our department. Diagnosis was confirmed byCT or MRI scanning. All tumours with diameter >10 mm were characterized by suprasellar extensions. Op.erations were performed via either sublabio-septo-sphenoidal approach or naso-vestibulo-sphenoidal approachunder microscope. A subarachnoid catheter was preoperatively inserted in the lumbar cistern, through whichsaline was slowly injected during operation to increase the intracranial pressure (ICP) so as to deliver thesuprasellar tumour into the operative field to aid the removal. Result: Of the 152 cases, the gross total removal of adenoma in 106 cases (69. 7% ) and subtotal removal in 37 cases (24. 4% ) were achieved, and partial removal was carried out in the remaining 9 cases (5. 9 % ) of fibrous or dumbbell-shaped adenomas. Therewere no deaths after operation in this group. Follow-up review (median 3. 5 years) in 137 patients revealedgood recovery in 97 patients (70. 8% ), and late recurrence in 40 patients (29. 2% ) who need reoperativemanagement, drug therapy, radiotherapy, or radiosurgery used either alone or combined. Conclusion: Microsurgical technique via transsphenoidal approach is a safe and effective way to remove the pitoitary adenomas with suprasellar extensions but not for fibrous or dumbbell-shaped ones.

Rathke Cleft Cyst with a Coexisting Gonadotropin Producing Pituitary Adenoma

Rathke cleft cyst is thought to arise from incomplete obliteration of the lumen of Rathke pouch. The cells of the anterior pituitary lobe, from which pituitary adenomas develop, are also derived from the cells of Rathke pouch. Although Rathke cleft cyst and pituitary adenoma have a shared ancestry, they rarely occur coincidentally. Rathke cleft cysts have been found incidentally in 11% - 33% of post-mortem examinations, and were associated with 1.7% - 2.1% of the pituitary adenoma cases. These coexisting lesions are difficult to diagnose pre-operatively due to the variable signal intensity and position of the Rathke cleft cysts. Treatment of these lesions involves surgical resection to decrease mass effect and medical management to normalize hormonal imbalances. To our best knowledge, only 42 cases of Rathke cleft cyst with a coexisting pituitary adenoma have been reported in the English or Japanese literatures, but none of the coexisting pituitary adenoma is gonadotropin producing. We would like to report a case of Rathke cleft cyst with a coexisting gonadotropin producing adenoma that was successfully treated by endoscopic endonasal transsphenoidal approach with the removal of the sellar lesion and temporary hormone replacement.

The Observation of Pituitary Function in Patients with Acute Pituitary Apoplexy before and after Transsphenoidal Surgery

Objective： To explore the pituitary function of acute pituitary apoplexy and its effect by transsphenoidal surgery. Methods： The clinical data and endocrine hormones level of 25 patients with acute pituitary apoplexy who underwent transsphenoidal surgery from Jan. 2002 to June 2004 were retrospectively analyzed. Results： 13 cases underwent surgery within 3 days after admission and 22 cases within 1 week. Of the 25 cases, 9 patients suffered the impairment of pituitary-thyroidal function, 14 cases of pituitary-adrenal function and 11 cases of pituitary-gonadal function before surgery. After surgery, 5/9, 8/14 and 7/11 were recovered from the corresponding hypopituitarism. Conclusion： Hypopituitarism is a major manifestation of acute pituitary apoplexy. Urgent surgery decompression contributed to the improvement of pituitary function. Patients with hypopituitarism after surgery required the corresponding hormones replacement therapy.
