Object. Closure of the sella turcica after transsphenoidal surgery is mainly accomplished with autologous muscle fascia and fat or muscle; this requires a second surgical incision. The authors review the results of using resorbable vicryl patches, gelatin foam, and fibrin glue for sellar reconstruction.Methods. A review was conducted of 376 consecutive patients who underwent surgery for pituitary adenomas, cysts, or subdiaphragmatic craniopharyngiomas in the sella turcica that the senior author (R.W.S.) had performed or directly supervised over the last 10 years. The sellar reconstruction was performed with a commercially available, synthetic absorbable patch composed of polyglactin 910/poly-p-dioxanone, gelatin foam, and fibrin glue. The patch is essentially resorbed in 2 to 3 months and replaced by fibrous collagen tissue. There were 117 small, 112 medium-sized, and 147 large lesions. The overall nonendocrine postoperative morbidity rate was 2.8%, and included visual deterioration, meningitis, secondary epistaxis, nasal septum complication, and cerebrospinal fluid (CSF) leakage. Two patients with macroadenomas needed reoperation for persistent CSF leakage, which comprised 0.5% of the whole series or 0.8% of the 259 patients with medium-sized or large lesions. There was no mortality and no morbidity related to the implanted material, and in particular no delayed empty sella syndrome.Conclusions. Closure of the sella turcica with a synthetic absorbable vicryl patch, gelatin foam, and fibrin glue after transsphenoidal surgery is safe and very effective in preventing postoperative CSF fistulas. The use of this technique obviates the need for a second surgical incision and shortens the operating time. Because of the progressive resorption of the substitute material, the interpretation of postoperative magnetic resonance studies was not significantly hindered.

✓ The authors treated two patients with pituitary apoplexy in whom magnetic resonance (MR) images were obtained before and after the episode. Two days after the apoplectic episodes, MR imaging demonstrated marked thickening of the mucosa of the sphenoid sinus that was absent in the previous studies. The relevance of this change in the sphenoid sinus was investigated. Retrospective evaluations were performed using MR images obtained in 14 consecutive patients with classic pituitary apoplexy characterized by acute onset of severe headache. The mucosa of the sphenoid sinus had thickened predominantly in the compartment just beneath the sella turcica, in nine of 11 patients, as ascertained on MR images obtained within 7 days after the onset of apoplectic symptoms. This condition improved spontaneously in all four patients who did not undergo transsphenoidal surgery. The sphenoid sinus mucosa appeared to be normal on MR images obtained from three patients at the chronic stage (> 3 months after onset). The incidence of sphenoid sinus mucosal thickening during the acute stage was significantly higher in the patients with apoplexy than that in the 100 patients without apoplexy. A histological study conducted in four patients who underwent transsphenoidal surgery during the early stage showed that the subepithelial layer of the sphenoid sinus mucous membrane was obviously swollen. The sphenoid sinus mucosa thickens during the acute stage of pituitary apoplexy. This thickening neither indicates infectious sinusitis nor rules out the choice of the transsphenoidal route for surgery.

Object. The authors have used a silicone plate for reconstruction of the sellar floor during rhinoseptoplastic transsphenoidal surgery because it has greater elasticity and is easier to carve than nasal septal cartilage and sphenoid sinus bone. This study was designed to evaluate the usefulness of this technique based on the authors' experience during the past 7.6 years. Methods. A silicone plate was used to reconstruct the sellar floor in 69 consecutive patients with sellar tumors that included 60 pituitary adenomas and nine Rathke's cleft cysts. The patients ranged in age from 16 to 82 years (mean 52 years). The postoperative position of the silicone plate could be clearly identified on sagittal or coronal magnetic resonance (MR) imaging as a very low intensity plate (void signal). No displacement or migration of the implanted silicone plate was observed on follow-up MR imaging in any patient. Infections of the lesion such as a pituitary abscess were not observed clinically or radiologically in any patient. Of the 16 patients with intraoperative cerebrospinal fluid (CSF) leakage, only one patient who had a ghost sella developed postoperative CSF rhinorrhea. In all seven patients who underwent repeated surgery for residual or recurrent tumor, the silicone plate that had been placed at the initial procedure was covered with a relatively thin fibrous capsule and the plate was well preserved. The silicone plate was easily removed at reoperation and was useful for detection of the sellar floor window made previously. Conclusions. These results indicate that a silicone plate can be useful for reconstruction of the sellar floor in rhinoseptoplastic transsphenoidal surgery.

✓ Pituitary abscess is an unusual cause of sella turcica enlargement. Because its presentation closely mimics that of a pituitary tumor, the condition is seldom recognized preoperatively. Most cases have been of bacterial etiology; however, a single patient with a primary mycotic pituitary abscess secondary to Aspergillus species has been reported. That patient died of diffuse Aspergillus meningoencephalitis following a transfrontal craniotomy. In the present case, a woman with primary pituitary aspergillosis survived her infection with virtually intact pituitary function following a transsphenoidal approach which avoided contamination of cerebrospinal fluid. Postoperative amphotericin-B and 5-fluorocytosine therapy probably contributed greatly to her survival. Factors that should alert the clinician to the presence of a pituitary abscess in a patient with sella turcica enlargement are prior episodes of meningitis, sinusitis, or cerebrospinal fluid abnormalities, including pleocytosis, depressed glucose, and elevated protein.

✓ Despite diagnostic advances, it remains difficult to identify intrasellar and ectopic parasellar adrenocorticotropic hormone (ACTH)—secreting microadenomas. The authors present the case of a 61-year-old woman with Cushing disease in whom a significant central-to-peripheral and lateralized right-sided ACTH gradient was demonstrated on inferior petrosal sinus sampling; no discernible abnormality was seen on magnetic resonance imaging. She underwent transnasal transsphenoidal surgery. No tumor was found on sellar exploration and a total hypophysectomy was performed, yet her hypercortisolemia persisted. The patient died of cardiac events 17 days postsurgery. Autopsy revealed an isolated, right-sided, intracavernous ACTH-secreting adenoma with no intrasellar communication. This case represents the first failed transsphenoidal surgery for Cushing disease in which there is postmortem confirmation of a suspected intracavernous sinus lesion. It supports the hypothesis that Cushing disease associated with nondiagnostic imaging studies, a strong ACTH gradient on venography, and negative findings on sellar exploration may be caused by an ectopic intracavernous ACTH-secreting adenoma. There are no premortem means of confirming the presence of such lesions, but these tumors could underlie similar cases of failed surgery. Radiation therapy targeting the sella turcica and both cavernous sinuses, possibly supplemented with medical treatment, is suggested for similar patients in whom transsphenoidal hypophysectomy has failed. Adrenalectomy may also be appropriate if a rapid reduction in ACTH is necessary.

✓ Two patients with diabetes insipidus, hypopituitarism, and an enlarged sella turcica underwent a transsphenoidal operation for the treatment of intrasellar germinomas. Successful transsphenoidal treatment of such neoplasms has not been reported previously. The cases indicate that the diagnostic possibility of intrasellar germinoma should be considered in young patients with combined diabetes insipidus and hypopituitarism, even when the sella is markedly expanded.

✓ A review of recent experience with transsphenoidal surgery for lesions in and about the sella turcica establishes the value of this approach for the management of patients with visual loss. The lesions encountered consisted of pituitary adenoma in 45 cases, craniopharyngioma in 10 cases, and miscellaneous tumors involving the sella in the remaining seven cases. Sixty of the 62 patients in this series had quantitative determination of preoperative and postoperative visual status; after surgery, vision was improved in 81%, unchanged in 11%, and worse in 5%. Two patients (3%) died during the immediate postoperative period before their visual status could be evaluated.

✓ Reconstruction of the sellar floor after pituitary tumor removal is sometimes difficult because the repair graft is difficult to handle in the narrow space. This is especially problematic if the endonasal endoscopic approach is used. The authors devised a technique to facilitate this procedure by placing a suture knot on the repair splint. This allows the material to be grasped securely with forceps and improves manipulation even within the narrow nasal cavity. This technique has proved useful when performing the endonasal endoscopic approach, and it is also expected to be useful when conducting the conventional sublabial transsphenoidal approach.

✓ The transnasal transsphenoidal approach is the preferred route for removal of most lesions of the sella turcica. The concept of transnasal surgery traversing the sphenoid sinus to reach the sella has existed for nearly a century. A comprehensive historical overview of the evolution of transsphenoidal surgery has been reported previously. In the present vignette, the authors focus on transsphenoidal surgery in the early 1900s, particularly on the methods advocated by Harvey Cushing and Oskar Hirsch, two prominent pituitary surgeons who pioneered the transsphenoidal technique. Cushing championed the sublabial approach, whereas Hirsch was the master of the endonasal route. Coincidentally, both surgeons independently performed the submucous septal resection for the first time on June 4, 1910. Although Cushing's and Hirsch's approaches were predicated on the work of their predecessors, their transsphenoidal procedures became the two most popular techniques and, for future generations of pituitary surgeons, laid the foundation for modern transsphenoidal surgery. In this comparative analysis, the authors compare the operative nuances of the approaches of Cushing and Hirsch and describe the contributions of these pioneers to modern transsphenoidal surgery.

✓ The authors describe a method of preventing cerebrospinal fluid (CSF) rhinorrhea following surgery for acoustic neurinoma. Mastoid air cells exposed during craniectomy are skeletonized and packed with bone dust, then covered with Surgicel soaked with Tisseel fibrin glue. The use of this technique has reduced the number of acoustic neurinoma cases requiring secondary mastoidectomy for CSF leakage from 16% to 5%.

Object. The optimal approach for the surgical treatment of craniopharyngiomas is still debated. In all cases involving the sella turcica, the authors have exclusively used transsphenoidal surgery (TSS), assuming that this approach is less traumatic than an intracranial one. Moreover, TSS was also performed in some cases of purely suprasellar craniopharyngiomas. In this study the surgical indications and the results obtained in all patients who had undergone TSS were analyzed. Methods. In a series of 92 patients who underwent surgery for craniopharyngiomas, TSS was the first choice of approach in 57 cases (62%) consisting of 29 female and 28 male patients with ages ranging from 12 to 79 years (mean 35 years). The follow-up duration ranged from 2 to 20 years. A standard transsphenoidal approach was used in patients with an exclusively intrasellar (11 patients) or an intrasellar and suprasellar tumor (37 patients); in nine cases of tumors located exclusively above the sella turcica, a transsphenoidal presellar approach (seven patients) or a transsellar—transdiaphragmatic approach (two patients) was used. Total removal was performed in 36 patients (63%). All patients had good clinical results. Postoperative cerebrospinal fluid leakage occurred in 10 cases, but only one case required a surgical repair of the sella. Two patients died of late complications (3.5%). There were eight cases (14%) of tumor regrowth. Conclusions. The authors assert that, when used in appropriately located craniopharyngiomas and by neurosurgeons with extensive experience in pituitary surgery, TSS offers excellent results with minor risks.
