    초록

    The rate of symptomatic improvement of visual symptoms associated with hematogenous metastases to the sella and pituitary was evaluated retrospectively in seven patients (five men, two women; mean age, 52.3 years) with primarily visual symptoms (diplopia alone in three, diplopia with blurred vision in one, blurred vision alone in one, loss of peripheral vision in one, and unilateral complete blindness in one). Symptom duration ranged from 0.5 to 2 months. The primary diseases were non-small cell lung cancer in two patients, renal cell carcinoma in two patients, prostate cancer in two patients, and medullary thyroid carcinoma in one patient. All patients had widespread metastatic disease. Three patients had a suprasellar tumoral component. One patient had a clival extension, and one patient had extension into the cavernous sinus. All underwent trans-sphenoidal surgery to correct visual symptoms. Gross total resection was achieved in three patients. Subtotal resections and a partial resection were performed in three patients and one patient, respectively. Surgical blood loss averaged 282 mL. One patient died from sepsis. Five patients developed complications (cerebrospinal fluid leakage in three, diabetes insipidus in two, anterior pituitary dysfunction in two, and colitis in one). At a mean follow-up of 15 months, three patients were alive. Visual symptoms improved in five patients and were unchanged in two. Trans-sphenoidal surgery helped improve visual symptoms in most patients. The morbidity rate was high and likely related to the locally destructive and extensive nature of the lesions in overall morbid patients with widespread metastatic disease. Unless nonoperative measures can provide equal results, however, this approach provides reasonable palliation.

  4. [해외논문]   Has management of epidermoid tumors of the cerebellopontine angle improved? A surgical synopsis of the past and present.

    Skull base : the official journal of North American Skull Base Society ... [et al.] v.18 no.2 ,pp. 85 - 98 , 2008 , 1531-5010 ,

    초록

    We compared the surgical outcomes of recent patients with cerebellopontine angle (CPA) epidermoids treated with advanced surgical tools with those of patients treated in earlier series. From November 2000 to June 2004, we treated 12 patients with epidermoid tumors. One patient had a strict CPA lesion. Tumors extended into the prepontine region in seven cases and supratentorially in two. In two cases the CPA was involved bilaterally. All patients but one underwent a lateral suboccipital approach in a semi-sitting position with microsurgical technique. Endoscopic assistance was used in cases with extensions beyond the CPA. In one case, a subtemporal route was used. The mean follow-up was 27 months (range, 8 to 50 months). There were no deaths. Total removal was achieved in 7 of the 10 patients with unilateral CPA epidermoids. Preoperative status improved in eight (80%) patients, particularly the function of cranial nerves (CNs) V and VII. Only two patients had permanent CN deficits. Complete excision with preservation of CN function should be the goals of management of epidermoids of the CPA. In some cases, these goals can be difficult to achieve, even with contemporary surgical equipment. Bilateral and extensive tumors should be removed in staged procedures. The function of CN V and CN VII may recover after decompression, but the outcome of symptoms related to CN VIII is less certain. The endoscope is a reliable tool for assessing the extension of epidermoids, but it cannot be used for tumor removal.

  5. [해외논문]   Benign extracranial nerve sheath tumors of the skull base: postoperative morbidity and management.  

    Biswas, Deb ; Marnane, Conor ; Mal, Ranjit ; Baldwin, David
    Skull base : the official journal of North American Skull Base Society ... [et al.] v.18 no.2 ,pp. 99 - 106 , 2008 , 1531-5010 ,

    초록

    The purposes of this retrospective case series study were to examine the outcome of the operative treatment of extracranial nerve sheath tumors (NSTs) of the skull base and to learn the optimal management. The study was conducted at a university teaching hospital and a regional referral center. A total of 19 cases of benign extracranial NSTs of the skull base who presented to the otolaryngology department over a period of 10 years were studied regarding the clinical, radiological, and pathological features and the operative and postoperative management. In the majority, these tumors originated from cranial nerves; postoperative complications were frequent and depended on the nerve of origin. Postoperative nerve deficit was apparent in 10 cases, and a second operation was necessary in 8 cases. The greatest postoperative morbidity was associated with the parapharyngeal NSTs (i.e., dysphagia in 30%, dysphonia in 30%, and Horner's syndrome in 20% of cases). The conclusion from this study is that high postoperative morbidity resulting from surgery on skull base NSTs demands an integrated approach between the otolaryngologist, plastic surgeon, neurosurgeon, speech therapist, physiotherapist, dietician, and occupational therapist and a clear strategy of long-term follow-up.

  6. [해외논문]   Petrous temporal bone cholesteatoma: a new classification and long-term surgical outcomes.  

    Moffat, David ; Jones, Stephen ; Smith, Wendy
    Skull base : the official journal of North American Skull Base Society ... [et al.] v.18 no.2 ,pp. 107 - 115 , 2008 , 1531-5010 ,

    초록

    The goals of this retrospective case review were to analyze the long-term results of surgery for petrous temporal bone cholesteatomas and to propose a new classification system for these lesions. Patients with a surgically confirmed petrous temporal bone cholesteatoma were treated at Addenbrooke's Hospital, a tertiary referral center. Postoperative facial function, hearing, residual/recurrent cholesteatoma, and other complications were assessed in relation to preoperative signs, intraoperative findings, and surgical approach. Between 1983 and 2004, 43 patients were treated. There were no perioperative deaths. There was no long-term recurrence in 95.4% of the patients, possibly because of meticulous surgical technique, bipolar diathermy, and use of the laser to denature the cholesteatoma matrix that was adherent to the dura. At presentation, 95% of the patients had no socially useful hearing in the affected ear. Facial nerve function, however, was usually preserved. Both direct anastomosis and nerve grafting can improve facial nerve function from House-Brackmann grade VI to grade III if the palsy is not longstanding. Four patients had cerebrospinal fluid leakage; other complications were rare. The proposed classification facilitates surgical planning and predicts the postoperative outcome with regards to hearing.

  8. [해외논문]   Vascular Decompression of Trigeminal and Facial Nerves in the Posterior Fossa under Endoscope-Assisted Keyhole Conditions.  

    Charalampaki, P ; Kafadar, A M ; Grunert, P ; Ayyad, A ; Perneczky, A
    Skull base : the official journal of North American Skull Base Society ... [et al.] v.18 no.2 ,pp. 117 - 128 , 2008 , 1531-5010 ,

    초록

    Objective: The aim of this study was to determine the use and safety of the endoscope as an adjunct during trigeminal and facial nerve decompression procedures performed under keyhole conditions in the posterior fossa. Method: We performed 67 surgeries in 65 patients with symptomatic trigeminal and facial nerve compression syndromes. The diagnosis was made mainly on the basis of clinical history, examination, and magnetic resonance imaging scans. Surgery was performed in all cases under endoscope-assisted keyhole conditions. The follow-up was 1 week postoperatively, 6 months, and then yearly up to 7 years. All 34 patients with trigeminal neuralgia received preoperative medication treatment and experienced failure with it. Eighteen patients out of 30 with hemifacial spasm had been previously treated with botulinum toxin injections. One patient suffered from both trigeminal neuralgia and facial spasm, because of a megadolichobasilar and vertebral artery with compression of both cranial nerves. Results: Sixty-four of the 65 patients became symptom free after surgical treatment; one revision surgery was necessary because of disappearance of the decompression muscle piece. No mortalities or minor morbidities were observed in this series. Conclusion: A precise planned keyhole craniotomy and the simultaneous use of the microscope and the endoscope render the procedure of the decompression less traumatic.

  9. [해외논문]   Postoperative acute sialadenitis after skull base surgery.  

    Kim, Louis J ; Klopfenstein, Jeffrey D ; Feiz-Erfan, Iman ; Zubay, Geoffrey P ; Spetzler, Robert F
    Skull base : the official journal of North American Skull Base Society ... [et al.] v.18 no.2 ,pp. 129 - 134 , 2008 , 1531-5010 ,

    초록

    During retrosigmoid and far-lateral skull base surgical approaches, the head may be positioned at the extreme limits of rotation and flexion. In rare instances, patients may develop acute sialadenitis after surgery as a result of this positioning technique. Over a 4-year period, five patients developed postoperative sialadenitis after undergoing either a retrosigmoid craniotomy in the supine position (n = 4) or a far-lateral craniotomy in the park-bench position. Based on all the retrosigmoid and far-lateral approaches performed by the senior author (RFS), the incidence of sialadenitis was 0.84%. In all five patients, the acute sialadenitis was not clinically apparent at the conclusion of the operation. However, the diagnosis was evident within 4 hours of surgery. In each case, the neck swelling in the vicinity of the submandibular gland was contralateral to the craniotomy site. All patients were treated with intravenous hydration and antibiotic therapy. One patient was extubated immediately after surgery with no obvious evidence of sialadenitis. However, she required emergent reintubation due to airway compromise. The mechanism of acute sialadenitis in these patients was obstruction of the salivary duct caused by surgical positioning. This previously unreported observation in patients undergoing skull base surgery deserves consideration during perioperative and postoperative management.
