    Although acupuncture has existed for over 2000 years, its application as an anesthetic aid began in the 1950s in China. The first surgical procedure performed under acupuncture anesthesia was a tonsillectomy. Soon thereafter, major and minor surgical procedures took place with electroacupuncture alone providing the anesthesia. The procedures performed were diverse, ranging from cardiothoracic surgery to dental extractions. Usage of acupuncture anesthesia, specifically in neurosurgery, has been well documented in hospitals across China, especially in Beijing, dating back to the 1970s. We present a case of a 65-year-old man who presented with right-sided body weakness. He had a past medical history of uncontrolled diabetes mellitus, hypertension, and obstructive sleep apnea requiring use of a nasal continuous positive airway pressure device during sleep. We performed a computed tomography brain scan, which revealed a left-sided acute on chronic subdural hemorrhage. Due to his multiple comorbidities, we decided to perform the surgical procedure under electroacupuncture anesthesia. The aim of this case report is to describe a craniotomy performed under electroacupuncture on an elderly patient with multiple comorbidities who was awake during the procedure and in whom this procedure, if it had been performed under general anesthesia, would have carried high risk.

    Intra-axial dermoid cysts are rare intracranial space occupying lesions, more so in the pediatric age group. Dermoid cysts account for about 0.2 to 1.8% of all intracranial tumors and are commonly located in the cisternal spaces, mainly in the cerebellopontine angle and parasellar cisterns. A purely intra-axial position as reported in this paper is quite exceptional.

    Awake craniotomy is a brain surgery in patients who are kept awake when it is indicated for certain intracranial pathologies. The anaesthetic management strategy is very important to achieve the goals of the surgery. We describe a series of our first four cases performed under a combination of scalp block and conscious sedation. Scalp block was performed using a mixture of ropivacaine 0.7% and adrenaline 5 5µg/ ml administered to the nerves that innervate the scalp. Conscious sedation was achieved with a combination of two recently available drugs in our country, dexmedetomidine (selective α 2-agonist) and remifentanil (ultra-short acting opioid). Remifentanil was delivered in a target controlled infusion (TCI) mode.

    We report a case of a 59 year old man who developed venous air embolism (VAE) during an elective craniotomy for parasagittal meningioma resection. The surgery was done in the supine position with slightly elevated head position. VAE was provisionally diagnosed by sudden decreased in the end tidal carbon dioxide pressure from 34 to 18 mmHg, followed by marked hypotension and atrial fibrillation. Prompt central venous blood aspiration, aggressive resuscitation and inotropic support managed to stabilize the patient. Post operatively, he was admitted in neuro intensive care unit and made a good recovery without serious complications.

    Barbiturate coma therapy (BCT) is a choice treatment for refractory intracranial hypertension after all surgical or medical managements have failed to control the intracranial pressure (ICP). It helps to reduce cerebral blood flow, cerebral metabolic rate of oxygen consumption and ICP. However, this therapy can also cause many complications. One of the underreported, but life-threatening complications is refractory hypokalemia, which can lead to subsequent rebound hyperkalemia after sudden cessation. We report our experience of managing unusual complication of refractory hypokalemia during BCT with thiopentone in postdecompressive craniectomy patient.

    Awake craniotomy is a brain surgery performed on awake patients and is indicated for certain intracranial pathologies. These include procedures that require an awake patient for electrocorticographic mapping or precise electrophysiological recordings, resection of lesions located close to or in the motor and speech of the brain, or minor intracranial procedures that aim to avoid general anaesthesia for faster recovery and earlier discharge. This type of brain surgery is quite new and has only recently begun to be performed in a few neurosurgical centres in Malaysia. The success of the surgery requires exceptional teamwork from the neurosurgeon, neuroanaesthesiologist, and neurologist. The aim of this article is to briefly describe the history of awake craniotomy procedures at our institution.

    Intracranial nail gun injury is a rare subset of penetrating head injury. Here we report a case of intracranial nail gun injury in a Vietnamese patient who attempted suicide with no neurological deficit. Three nails were launched. Because the nail head acted as a brake, the launched nail could make a hole into the skull but could not entirely pass it. A rational management strategy should permit these patients to be discharged with no additional injury. Some medical and surgical management in penetrating head injury are discussed. The use of antibiotics and antiepileptic drugs and the retraction of the nail aided by the performance of a craniotomy surrounding the entry point are recommended.

    A 47-year-old lady, presented with progressive proptosis of left eye with deterioration of vision. She had a history of left solitary fibrous tumour and had undergone left frontal craniotomy and orbitotomy in 2004. Surveillance Magnetic resonance imaging (MRI) six years later showed tumour recurrence with intracranial extension. However, she did not follow-up and only presented again 3 years, later. Tumour resection and left exenteration was performed. Histology showed ‘patternless’ pattern of neoplastic cells, and CD34 staining was diffusely positive. Diagnosis of recurrent solitary fibrous tumour with intracranial extension was made.

    Objective: This case report highlights psychosis post craniopharyngioma surgery.

    Methods: We report a case of a young Malay lady who presented with psychotic symptoms after she underwent craniotomy for craniopharyngioma.

    Results: Presence of prominent hallucinations and delusions after removal of the tumour and the symptoms lasted more than a month. The psychosis subsided with antipsychotic.

    Conclusion: Psychosis post craniopharyngioma surgery is still possible whether possibly due to the residual tumour or as a result of treatment sequealae.

    Metastatic tumors are the most common mass lesions in the brain. This case reports a rare form of sarcoma with metastasis to the brain. The appropriate management of a patient with metastatic alveolar soft part sarcoma to the brain is discussed. Author describes a 32-year-old gentleman diagnosed with primary tumor at gluteus and distant metastases at lower lobe of right lung and the brain. Histopathology proves diagnosis as alveolar soft part sarcoma. Craniotomy with excision of brain lesion was done. Repeated magnetic resonance imaging of the brain after 2 months showed rapidly growing new lesions. The next step of management was made by the oncology team as recurrence rate was high and due to multi-systemic involvement. Patient was planned for palliative chemotherapy and to be reassessed later. This case report discusses the appropriate approach to any form of brain metastases and the role of early follow-up especially after surgery for better outcome and choice of post operative management such as radiotherapy or chemotherapy or both for malignant tumors. Based on this report, it was concluded that every brain tumor patient should be frequently monitored even in the outpatient setting as most of them are metastatic and rapidly spreading. The patient should be considered for radiotherapy or chemotherapy or both after surgery if the histopathology result is suggestive of malignancy.

    Chronic granulomatous mastitis is known as a benign and relatively rare disorder that is often difficult to differentiate from breast carcinoma. We highlight the case of a 34-year-old woman who had recurrent episodes of right breast swelling and abscess for 8 years. These were proven to be chronic granulomatous mastitis by tissue biopsies on 3 different occasions. Her condition improved on similar courses of antibiotics and high-dose prednisolone. However, she subsequently developed progressive loss of vision due to an orbital tumour. She then underwent a craniotomy and left orbital decompression with excision of the tumour, which proved to be a metastatic carcinoma. A trucut biopsy of the right breast was then done and showed features consistent with an infiltrating ductal carcinoma. This case illustrates the possibility that chronic granulomatous mastitis could be a precursor for malignancy and the difficulty in differentiating one from the other. The possible mechanisms of development and the implications for future management are also discussed.

    We studied the efficacy of two surgical methods used for the treatment of intracranial subdural empyema (ISDE) at our centre. A cross-sectional study (1999-2005) of 90 patients with non-traumatic supratentorial ISDE revealed that the two surgical methods used for empyema removal were burr hole/s and drainage (50 patients, 55.6%) and a cranial bone opening procedure (CBOP) (40 patients, 44.4%). Patients in the CBOP group had a better result in terms of clinical improvement (chi-squared analysis, p=0.006) and clearance of empyema on brain CT scan (chi-squared analysis, p<0.001). Reoperation was more frequent among patients who had undergone burr hole surgery (multiple logistic regression, p<0.001). The outcome and morbidity of ISDE survivors were not related to the surgical method used (p>0.05). The only factor that significantly affected the morbidity of ISDE was level of consciousness at the time of surgery (multiple logistic regression, p<0.001). We conclude that CBOP and evacuation of the empyema is a better surgical method for ISDE than burr hole/s and drainage. Wide cranial opening and empyema evacuation improves neurological status, gives better clearance of the empyema and reduces the need for reoperation. Level of consciousness at the time of presentation is a predictor of the morbidity of ISDE. Thus, aggressive surgical treatment should occur as early as possible, before the patient deteriorates.

    Craniofacial resection is commonly performed in the surgical resection of sinonasal tumours involving anterior skull base. It entails a bicoronal scalp flap with lateral rhinotomy or an extended lateral rhinotomy to expose the anterior skull base. Transfacial approach is necessary in the resection of the nasal part of the tumour. The choice of surgical approach is based heavily on the surgeon's experience and training. The results of endoscopic-assisted craniofacial resection for sinonasal tumours performed in our center in eight patients from 1998 to 2005 were reviewed. There were seven males and one female with age ranging from 18 to 62 years (mean 42.4 years). There was each a case of mature teratoma, poorly differentiated squamous cell carcinoma, undifferentiated squamous cell carcinoma, olfactory neuroblastoma, fibrous dysplasia, inverted papilloma and two cases of sinonasal neuroendocrine carcinoma. The mean follow up duration for these eight patients post surgery was 21.4 months. Out of eight patients, five underwent surgery with no adverse complications. The complications encountered were a cerebrospinal leak and a postoperative transient V and VI cranial nerve palsy. One patient with sinonasal undifferentiated carcinoma died of lung metastasis at 11 months post-surgery. The endoscopic-assisted craniofacial resection is a highly useful surgical technique to avoid the unsightly facial scar of the lateral rhinotomy or the Weber-Ferguson incision, postoperative paranasal sinuses infection and avoidance of tracheostomy in selected cases. We found that this approach has lower morbidity rate in selected cases.

    A 27-year-old patient presented with severe headache and seizures about a month after the initial head trauma. Computed tomography (CT) brain scan revealed acute subdural bleed continuous into the interhemispheric region, with no subarachnoid haemorrhage. This was due to rupture of a traumatic pericallosal artery aneurysm. This represents a rare case of traumatic pericallosal artery aneurysm presenting with subdural haematoma without subarachnoid haemorrhage.

    Surgical site infection (SSI) after craniotomy even though rare, poses a real risk of surgery and represents a substantial burden of disease for both patients and healthcare services in terms of morbidity, mortality and economic cost. The knowledge of risk factor for surgical site infection after craniotomy will allow the authority to implement specific preventive measures to reduce the infection rate. Therefore, the objectives of this study are to determine the incidence and the risk factors of surgical site infection after craniotomy.

    BACKGROUND: Replacing the skull defect with synthetic materials for hyperostotic bone secondary to meningioma is recommended owing to the possibility of tumor invasion. In our institution, neurosurgeons have been putting back the refashioned hyperostotic bone flap after meningioma excision because of budget constraints. The aim of this study was to review the long-term meningioma recurrence rate in these patients.

    METHODS: This was a nonrandomized, prospective observational study conducted from September 2011 to January 2015 on patients with intracranial convexity and parasagittal meningiomas. Preoperative computed tomography brain scans were obtained in all patients to confirm bony hyperostosis. Intraoperatively, part of the hyperostotic bone was sent for histopathologic examination. The rest of the bone flap was refashioned by drilling off the hyperostotic part. The bone flap was put back over the craniotomy site after soaking in distilled water. All patients were followed up for tumor recurrence.

    RESULTS: The study included 34 patients with convexity or parasagittal meningioma World Health Organization grade I-II who underwent Simpson grade Ia and IIa excision. Median follow-up was 63.5 months (mean 64.9 ± 9.4 months). The hyperostotic bone flap showed presence of tumor in 35% of patients. There were 2 patients with parasagittal meningiomas after Simpson grade IIa resections who developed tumor recurrences.

    CONCLUSIONS: Our study found that meningioma recurrence was unlikely when autologous cranioplasty was done with refashioned hyperostotic bone. This could be done in the same setting with meningioma excision. There was no recurrence in convexity meningiomas at mean 5-year follow-up.

    BACKGROUND: Magnetoencephalography (MEG) is a method of functional neuroimaging. The concomitant use of MEG and electrocorticography has been found to be useful in elucidating neural oscillation and network, and to localize epileptogenic zone and functional cortex. We describe our early experience using MEG in neurosurgical patients, emphasizing on its impact on patient management as well as the enrichment of our knowledge in neurosciences.
    MATERIALS AND METHODS: A total of 10 subjects were included; five patients had intraaxial tumors, one with an extraaxial tumor and brain compression, two with arteriovenous malformations, one with cerebral peduncle hemorrhage and one with sensorimotor cortical dysplasia. All patients underwent evoked and spontaneous MEG recordings. MEG data was processed at band-pass filtering frequency of between 0.1 and 300 Hz with a sampling rate of 1 kHz. MEG source localization was performed using either overdetermined equivalent current dipoles or underdetermined inversed solution. Neuromag collection of events software was used to study brain network and epileptogenic zone. The studied data were analyzed for neural oscillation in three patients; brain network and clinical manifestation in five patients; and for the location of epileptogenic zone and eloquent cortex in two patients.
    RESULTS: We elucidated neural oscillation in three patients. One demonstrated oscillatory phenomenon on stimulation of the motor-cortex during awake surgery, and two had improvement in neural oscillatory parameters after surgery. Brain networks corresponding to clinico-anatomical relationships were depicted in five patients, and two networks were illustrated here. Finally, we demonstrated epilepsy cases in which MEG data was found to be useful in localizing the epileptogenic zones and functional cortices.
    CONCLUSION: The application of MEG while enhancing our knowledge in neurosciences also has a useful role in epilepsy and awake surgery.
