Surgical intervention has been offered to patients with Meniere's disease who have failed medical treatment and have disabling symptoms. Surgical options have included labyrinthectomy (mechanical and chemical), vestibular neurectomy, and endolymphatic sac surgery with or without shunting. We present a modification of endolymphatic sac decompression surgery that includes wide decompression of th...

Since the first article introducing doubleballoon endoscopy (DBE) was published in 2001 [1], the technique has proven effective for deep intubation of the small bowel and is used in clinical practice worldwide. However, the intubation depth is sometimes limited by the distension of the small bowel due to air insufflation during the procedure. In a recent report [2], the total success rate using...

This research explores any potential for an on-chip cache compression which can reduce not only cache miss ratio but also miss penalty, if main memory is also managed in compressed form. However, decompression time causes a critical effect on the memory access time and variable-sized compressed blocks tend to increase the design complexity of the compressed cache architecture. This paper sugges...

OBJECTIVE To discover design principles underlying the optimal waveforms for external chest and abdominal compression and decompression during cardiac arrest and cardiopulmonary resuscitation (CPR). METHOD A 14-compartment mathematical model of the human cardiopulmonary system is used to test successive generations of randomly mutated external compression waveforms during cardiac arrest and r...

We present a 52-year-old gentleman with an unusual cause of progressive dysphagia, namely due to extrinsic lower oesophageal compression from a cystic mass of the posterior mediastinum. Cystic masses in adults are uncommon, and there is a wide differential diagnosis. This includes neoplastic, such as germ cell tumour (cystic teratoma), and non-neoplastic aetiologies. The later include foregut d...

The purpose of the present study was to describe a new minimally invasive surgical technique for decompression of the ulnar nerve at the elbow for treatment of cubital tunnel syndrome. Four patients underwent surgical treatment for cubital tunnel syndrome. Preoperative clinical states were classified by using the McGowan grading system and the postoperative states were recorded by using the Wil...

A consecutive series of 75 patients with syringomyelia is presented, all of whom were treated by cranio-vertebral operations. Attention is drawn to the difficulty in assessing the results of treatment but 56 stabilised or showed modest improvement after surgery. Occluding the central canal appeared to have no greater influence on the progression of the disease than did simple decompression and ...

objective: an assessment of  nonoperative and operative intervention in regards  to  neurological  improvement  following  traumatic  closed  cervical spinal cord injury (csci). method: a retrospective evaluation of a cohort of patients with a csci from c3 to t1 was reviewed. the analysis included a total of 13 eligible patients. the  neurologic  and  functional outcomes  were  recorded  from  ...

A Chiari malformation Type I may remain asymptomatic until the patient has reached adulthood and acute presentation of symptoms occurs. In several clinical and experimental studies it has been shown that essential hypertension is associated with vascular compression of the brainstem, particularly of the rostral ventrolateral medulla oblongata. Nevertheless, two cases of Chiari malformation and ...

Reported are a total of 81 microsurgical operations for cranial nerve root decompression comprising of 66 trigeminal, 10 facial, one vestibular, one vagus and three accessory nerve dysfunction syndromes from 1983 to 1990. Almost all cases of trigeminal neuralgia (TNG) secondary to vascular (59 cases) and minute mass (10 cases) compression, and those with hemifacial spasm (HFS) (nine out o...
