OBJECTIVE: The objective of this study was to investigate the diagnosis and management of skull base osteoradionecrosis (ORN) after radiotherapy for nasopharyngeal carcinoma (NPC). METHODS: The general information, clinical manifestations, and treatment outcomes were retrospectively evaluated in 15 patients with skull base ORN after radiotherapy for NPC. RESULTS: The common symptoms of skull base ORN included foul odor, headache, and epistaxis. Endoscopic examination showed exposed bone or sequestration in the nasopharynx. The characteristic findings according to computed tomography included the following: bone was destroyed extensively and symmetrically or regionally; bone was exposed to the air cavity; sequestration can be observed; and small air bladder was present in the parenchyma. There were nine patients regional skull base ORN receiving surgery, two of whom died of postradiation temporal lobe necrosis and seven of whom survived for 2 to 7 years. Conservative treatments were provided to six patients, including five patients with extensive skull base ORN and one patient with regional ORN, among which three patients died of nasopharyngeal bleeding, one patient died of exhaustion, and two patients survived for 3 to 5 years. CONCLUSIONS: Clinical diagnosis of skull base ORN was based on symptoms, computed tomography, or magnetic resonance imaging and endoscopy. The final confirmation was according to pathologic examination. Surgery had the best effect. Extensive ORN accompanied by radiation brain damage or cranial nerves damage had poor prognosis. Nasopharyngeal bleeding and exhaustion were the main causes of death. 相似文献

OBJECTIVE: To evaluate the results of salvage surgery for patients with primary recurrence of nasopharyngeal carcinoma after radiotherapy. DESIGN: Cohort study. SETTING: Academic tertiary referral center. PATIENTS: Eighteen consecutive patients with primary recurrence of nasopharyngeal carcinoma after radiation failure underwent nasopharyngectomy for cure via a facial translocation approach from July 1, 1993, to December 31, 1999. Follow-up ranged from 3 to 71 months. Five patients with skull base invasion required a combined neurosurgical approach to treatment. Seven patients had additional postoperative radiotherapy. RESULTS: The actuarial 3-year survival was 57%, while the local control was 78%. Four of 5 patients who had skull base invasion achieved local control. There was no surgical mortality, and the morbidity was 22%. CONCLUSION: Advances in skull base surgery make possible the effective control of primary recurrence of nasopharyngeal carcinoma, with acceptable mortality and morbidity. 相似文献

Objectives: Osteoradionecrosis is one of the most serious and devastating complications of radiotherapy. The proper management of osteoradionecrosis is currently undetermined. The objective of this study is to evaluate the treatment results of a systematic approach to osteoradionecrosis. Study Design: A prospective study of a systematic approach to osteoradionecrosis in the head and neck area was undertaken. Methods: From July 1993 to June 1998, 33 cases of osteoradionecrosis in the head and neck area were treated using a systematic approach that combined sequestrectomy and hyperbaric oxygen therapy. Results: Seven (21%) had recurrent cancer. The control rate of the other 26 osteoradionecrosis cases was 77% (20/26). Conclusions: Persistent osteoradionecrosis, despite diligent radical treatment, raises the suspicion of recurrent cancer. Extensive osteoradionecrosis with a multiple discharging fistula, a large area of exposed necrotic bone, or a coexistent fracture should be treated primarily with radical sequestrectomy and microvascular free flap reconstruction. Surgery still plays a major role in controlling osteoradionecrosis, and hyperbaric oxygen therapy is adjuvant. 相似文献

Objectives In patients with nasopharyngeal carcinoma (NPC), the differentiation between recurrent primary cancer and osteoradionecrosis (ORN) is clinically difficult. Epstein‐Barr virus (EBV)‐derived latent membrane protein‐1 (LMP‐1) has been demonstrated to be highly associated with NPC. The objective of this study is to define the role of the LMP‐1 gene in the differential diagnosis of recurrent NPC and ORN. Study Design Prospective. Methods From July 1998 to June 2000, 15 postirradiated patients with NPC who were initially diagnosed to have skull base ORN underwent endoscopic sequestrectomy. The sequestra were examined for the presence of the LMP‐1 gene and cancer. Results Two of 15 patients had recurrent cancer and only these two patients demonstrated a positive LMP‐1 gene in their surgically removed sequestra. The presence of the LMP‐1 gene in the sequestrum coincided with biopsy‐proven local recurrence. Conclusions The LMP‐1 gene is a potential marker to differentiate between recurrent NPC and ORN. The presence of the LMP‐1 gene in patients with ORN may indicate local recurrence. 相似文献

OBJECTIVE: The objective of this study was to examine the role of endoscopic approaches to the resection of anterior skull base and paranasal sinus malignancies at one tertiary care medical center. STUDY DESIGN: The authors conducted a retrospective chart review over a period of 17 years. METHODS: Patients undergoing anterior skull base resections for malignancies over a 17-year period were reviewed. Data were collected on each patient with respect to the pathology of the tumor and approach used as well as demographic and follow-up information. RESULTS: A total of 78 patients were treated at a tertiary care medical center for malignancies of the paranasal sinuses and anterior skull base. The most common diagnosis was squamous cell carcinoma occurring in 33% of the cases. The remaining pathologies included esthesioneuroblastoma (23%), adenoid cystic carcinoma (15%), melanoma (3%), sinonasal undifferentiated carcinoma (3%), lymphoma (5%), nasopharyngeal carcinoma (4%), and other tumor types (14%). Endoscopic techniques were used extensively in this population of patients. Combined approaches using a sublabial/transmaxillary approach and coronal approaches were used when indicated and complemented the endoscopic approach. A majority of patients were without evidence of disease at the end of this review. Using endoscopic techniques allowed for acceptable cosmetic results and facial incisions were used minimally. CONCLUSION: With complete endoscopic surgical resection followed by radiation therapy, local recurrence, morbidity, and cosmetic deformity have been minimized. The microscopic view provided by endoscopic techniques, with or without complementary approaches, allows for complete tumor removal. 相似文献

INTRODUCTION: The increasing expertise of transnasal endoscopic surgery has recently expanded its indications to include the management of tumours affecting the skull base. We report our experience with endoscopic management of these tumours, emphasising the indications and surgical technique used. MATERIAL AND METHOD: A retrospective analysis was performed of patients treated by an endoscopic endonasal approach (EEA) in our department from 2004 until 2011. RESULTS: Sixty-three patients were analysed. We performed an endoscopic craniofacial resection in 32 patients (51%), an expanded EEA in 22 (35%), a transclival approach in 6 (9%) and a transpterygoid approach in 3 (5%). The most frequent benign tumour was nasopharyngeal angiofibroma (24%), while adenocarcinoma (30%) was the most common among malignancies. Mean follow-up was 26 months (range: 6 to 84 months). The complication rate was 5% and resection was complete in 56 cases (89%). The 5-year overall-survival was 71% in patients with malignant tumours and the effectiveness was 100% in benign tumours. CONCLUSION: Our results support that endoscopic surgery, when properly planned, represents a valid alternative to standard surgical approaches for the management of skull base tumours. 相似文献

Malignant external otitis or skull base osteomyelitis and osteoradionecrosis of the skull base and the skull are potentially life-threatening conditions. The standard methods of treatment involve the use of antibiotics, local treatment and, where necessary, surgical excision of necrotic tissue. These approaches do not provide a complete cure in many cases. Severe functional deficits and even death can occur in advanced stages. We conducted a long-term retrospective follow-up study and report on a multimodal approach that we have been using with great success since 1987. The four cornerstones of this treatment are surgical debridement, combinations of antibiotics, specific immunoglobulins, and adjunctive hyperbaric oxygen therapy. This multimodal treatment approach has proved to be highly effective in improving the survival and quality of life of the patients concerned. These excellent outcomes justify the high costs that this therapy admittedly involves. 相似文献

BACKGROUND: Juvenile nasopharyngeal angiofibromas (JNAs) are highly vascular tumors that originate in the nasopharynx of young males. The primary treatment is surgical excision. Traditional surgical approaches are associated with significant morbidity and facial deformity. We introduce and outline the clinical advantages of an endoscopic surgical approach to JNAs using the Nd:YAG laser with image-guided surgery. DESIGN: Case series. SETTING: Tertiary care medical center. PATIENTS AND METHODS: Our study included 5 male patients (age range, 8-21 years) with extensive JNAs. Their tumors were large and ranged from Fisch stage IIA to IIIA. Embolization of tumor-feeding vessels was performed before surgery. The tumors were photocoagulated via a transnasal endoscopic approach using a Nd:YAG laser. Devascularized, lased tumor was removed with a microdebrider. Image-guided navigation systems were used to assist skull base tumor removal, and sublabial and buccolabial incisions were used as needed to gain lateral endoscopic tumor access. Endoscopic tumor margins were obtained for frozen section. RESULTS: All patients achieved symptomatic remission, with no complications. No blood transfusions were necessary. The patients were ready for discharge 1 to 2 days after surgery. Postoperative and magnetic resonance imaging scans showed 2 skull base recurrences, which were removed endoscopically. Follow-up ranged between 2 and 3 years. CONCLUSIONS: Traditional external surgical approaches to large JNAs may result in significant morbidity. Laser-assisted image-guided endoscopic excision of JNAs is a safe and effective minimally invasive surgical treatment. Its distinct advantages include (1) diminished blood loss, (2) superior cosmesis without observed altered facial growth, (3) direct access of skull base with minimal morbidity, and (4) ease of endoscopic follow-up. 相似文献

OBJECTIVES: To evaluate the potential use of contact endoscopy for the diagnosis of nasopharyngeal carcinoma (NPC). STUDY DESIGN: Prospective study to examine the nasopharynx of 30 patients with nasopharyngeal carcinoma and 18 subjects with normal nasopharynx in a clinic setting using contact rhinoscopes (Karl Storz, Tuttlingen, Germany, 7215 AA, 00 and 7215 BA, 300; 23 cm long; 4 mm in diameter). METHODS: The superficial cells of the normal nasopharynx and the nasopharyngeal tumors were stained with 1% methylene blue and examined with contact rhinoscopes at high magnifications (x 60 and x 150). The areas under examination were then biopsied. The contact endoscopic images were compared with the corresponding hematoxylin and eosin-stained histologic sections of the biopsied tissues. RESULTS: Sixty-six procedures were performed in 48 patients. The images of normal pseudostratified ciliated epithelium and squamous epithelium were readily recognized by contact endoscopy in all subjects with normal nasopharynx (10 men and 8 women; mean age, 51.9 y). Twenty-six of 30 patients with NPC (86.6%; 18 men and 8 women; mean age, 50.6 y) were successfully examined by contact endoscopy under local anesthesia. In these 26 patients, two patterns of malignant cells were identified with contact endoscopy. The patterns of contact endoscopic images corresponded well with the histologic findings. CONCLUSION: Contact endoscopy is an accurate and reliable office-based procedure, which allows for in-vivo diagnosis of nasopharyngeal carcinoma. 相似文献
