Wide Access

The transsphenoid approach to cystic lesions of the petrous tip has been made possible by the advances in techniques for diagnosis. These include polytomography, improved angiography, and computer tomographic (CT) brain scanning. The results of these studies can determine the size, shape, and thickness of the cystic lesion, as well as its exact relationship to the sphenoid sinus. A number of surgical approaches have been used to reach the cystic lesion of the petrous apex. Most notably, these include the middle fossa extradural craniotomy and posterior fossa craniotomy. These surgical techniques allow the cyst to be biopsied but do not establish permanent drainage. The translabyrinthine approach accomplishes wide access to the petrous apex, but cochlear and vestibular functions are sacrificed. The transsphenoid approach to cystic lesions of the petrous apex should be the ideal operation provided that the anterior aspect of the cyst abuts against the posterior wall of the sphenoid sinus. The cyst can be completely evacuated and permanent fistulization established into the sphenoid sinus using a septal mucosal flap and a silicone drainage device. The operation is accomplished without destruction to the inner ear.

Review Of The Literature

AbstractObjective:We report a case of cholesterol granuloma of the petrous apex which was surgically treated via an endoscopic trans-sphenoidal approach.Methods:Case report and review of the literature concerning cholesterol granulomas of the petrous apex and their management.Results:The lesion was approached endoscopically via a bilateral sphenoidotomy with removal of the vomer. A large cholesterol granuloma was evacuated and marsupialised. The patient made an uneventful recovery.Conclusion:Trans-sphenoidal access to the petrous apex represents an alternative route for the drainage and ventilation of cholesterol granulomas. This approach is the technique of choice when the cholesterol granuloma abuts the posterior wall of the sphenoid sinus. The trans-sphenoid approach, unlike other lateral approaches to the petrous apex, spares cochlear and vestibular function and allows post-operative endoscopic follow up.

AbstractThe first case of a primary mucocele of the petrous apex is presented and the differential diagnosis is briefly discussed. Since this area is unavailable for direct examination, a thorough radiographic evaluation is essential. A mucocele should be suspected when a lytic lesion has a multiloculated appearance and when the contralateral petrous apex is highly pneumatized. Even then, a biopsy may still be needed to make a definitive diagnosis. The appropriate treatment for these cystic lesions is fistulization into a radical mastoid cavity or an exteriorized sphenoid sinus.

Surgical Approaches

The authors describe biopsy of a petrous apex lesion via a transnasal, transsphenoidal endoscopic approach. Various surgical approaches to the petrous apex are discussed as well as our experience using the endoscopic approach. We propose that this approach can be refined for future use as a method for biopsy and permanent fistulization of cystic petrous apex lesions that encroach on the sphenoid sinus.

First Time

The transsphenoid approach to the petrous apex, a surgical procedure described for the first time by Montgomery in 1977, is a rarely performed approach for the drainage and ventilation of cholesterol granuloma. We consider this approach to be the technique of choice when the cholesterol granuloma is located in the medial section of the petrous apex abutting and/or prolapsing into the posterior wall of the sphenoid sinus. The transsphenoid approach, unlike other lateral approaches to the petrous apex, is highly conservative and spares cochlear and vestibular function; moreover, it allows simple and adequate post-operative endoscopic follow up as an out-patient, with easier treatment in the case of recurrence.

Selection Of

The treatment of metastatic spinal cord compression is complex. The three treatment modalities that are currently applied (in a histologically non-specific manner) are surgery, radiotherapy and the administration of steroids. The development of new spinal instrumentations and surgical approaches considerably changed the extent of therapeutic options in this field. These new surgical techniques have made it possible to resect these tumours totally, with subsequent vertebral reconstruction and spinal stabilization. In this respect, it is important to clearly identify those patients who can benefit from such an extensive surgery. We present our management algorithm to help select patients for surgery and at the same time identifying those for whom primary non-surgical therapy would be indicated. The retrospective review of surgically treated patients in our department in the last four years reveals a meagre application of conventional guidelines for the selection of the appropriate operative approach in the surgical management of these patients. The reasons for this discrepancy are discussed.

Abstract Background There are few articles about the surgical techniques of thalamic glioma and the lesions in the basal ganglia area. According to three existing cases and the literature review (Twelve articles were summarized which mainly described the surgical techniques), we discuss the surgical characteristics of lesions of the thalamus and basal ganglia area and summarize the relevant surgical skills. Case presentation Of the three cases, two were thalamic gliomas and one was brain abscess in basal ganglia. According to the three-dimensional concept of the “Four Walls, Two Poles”, lesions of the thalamus and basal ganglia were surgically removed, and the operative effect was analysed by relevant surgical techniques. Surgical resection of the lesions of the thalamus and basal ganglia area according to the three-dimensional concept of the “Four Walls, Two Poles” has achieved good surgical results. Relevant surgical techniques, such as the use of retractors, the use of aspirators, the choice of surgical approaches, and the haemostasis strategy, also played an important role in the operation process. Conclusions In the presented three cases the three-dimensional concept of the “Four Walls, Two Poles” allowed for safe surgical resection of lesions of the thalamus and basal ganglia.

Abstract Objective Primary orbital malignancy is rare. Awareness of the characteristic clinical and imaging features is imperative for timely identification and management. Surgery remains an important diagnostic and treatment modality for primary orbital malignancy, but determining the optimal surgical approach can be challenging. The purpose of this article is to explore recent advances in the diagnosis, management, and surgical approaches for primary orbital malignancies. Design In this review, the clinical presentation, imaging features, and medical and surgical management of primary orbital malignancies with representative cases will be discussed. Setting Outpatient and inpatient hospital settings. Participants Patients with diagnosed primary orbital malignancies. Main Outcome Measures Descriptive outcomes. Results Advancements in orbital imaging, microsurgical techniques, and multimodal therapy have improved the diagnosis and management of primary orbital malignancies. Special considerations for biopsy or resection are made based on the tumor's location, characteristics, nearby orbital structures, and goals of surgery. Minimally invasive techniques are supplanting traditional approaches to orbital surgery with less morbidity. Conclusions Advances in imaging technologies and surgical techniques have facilitated the diagnosis and management of primary orbital malignancies. Evolution toward less invasive orbital surgery with focus on preservation and restoration of function is underway.

Abstract Background Endometriosis of the uterine body can be manifested as diffuse solid lesions or cystic lesions. The former is common, while the latter is rare, especially for cystic adenomyosis larger than 5 cm. Case presentation A 30-year-old woman was admitted for severe and worsening dysmenorrhea. Ultrasound examination revealed a rare well-circumscribed cystic lesion about 5.5 × 4 × 5.0 cm. CA-125 level was slightly elevated. She accepted laparoscopic surgery and the adenomyotic tissues were excised. The histopathology of the specimen demonstrated the endometrial glands in the walls of cysts and an area of extensive hemorrhage can be seen in the inner wall of cyst. The patient made a good recovery after surgery and her symptoms complete resoluted. Conclusions This is a rare case of a cystic adenomyotic lesion that was treated by laparoscopic surgery.

Petrous Temporal Bone

AbstractSporadic case reports and the few published series of expanding lesions of the deep petrous temporal bone propose a variety of surgical approaches to ensure excision. All such surgery represents a compromise between exposure adequate for total removal and avoidance of further neurological deficit. Unfortunately pathology in the petrous apex evolves relatively silently and diagnosis is delayed. In many cases total excision is impossible. We present a series of patients presenting with advanced tumours of the deep petrous temporal bone in order to illustrate the spectrum of disease encountered, the limited role of surgery and the natural history of irresectable pathology in this remote and inaccessible area.

Objectives: We identified the optimal approaches for treating the diverse tumor subtypes of petroclival meningioma (PM) by analyzing the clinical benefits of various surgical approaches adopted for each subtype.Methods: Tumors in 102 PM patients from a single center who underwent surgical treatment were classified as upper clivus (UC), cavernous sinus (CS), tentorium (TE), or petrous apex (PA) types based on the attachment site of the tumor base and the displacement of the trigeminal nerve. The therapeutic effects of different surgical approaches among the subtypes were evaluated according to the patient outcomes.Results: The subtemporal (33.33%), retrosigmoid (16.67%), and Kawase approaches (50%) were used for the UC type. Simpson I/II resection was achieved in 46.66% of patients with the Kawase approach. Significant differences were found between the other two approaches (P = 0.044) and in the follow-up Karnofsky performance scale (KPS) scores (P = 0.008). The subtemporal (60%) and Kawase approaches (40%) were used for the CS type; neither approach achieved Simpson I/II resection. The retrosigmoid (25.81%) and Kawase approaches (74.19%) were used for the TE type. The Simpson I/II resection rates of the two approaches were 55.55 and 86.95%, respectively, and a significant difference was observed between them (P = 0.039). The retrosigmoid (43.75%) and Kawase approaches (56.25%) were used for the PA type. The Simpson I/II resection rates of the two approaches were 31.25 and 50%, respectively. The resection degrees of the two approaches and the KPS scores at follow-up were significantly different (P = 0.034).Conclusion: The individual microsurgical approaches adopted for the various PM tumor subtypes can provide maximal safe resection and good KPS scores. The Kawase approach is more suitable for PM, especially for UC- and PA-type PM tumors.
