Treatment of delayed Chiari malformation and syringomyelia after lumboperitoneal shunt placement: Case report and treatment recommendations.

Background: Delayed Chiari malformation with syringomyelia is an uncommon and sparsely reported complication after lumbar cisternal shunting. A number of treatments have been implemented with varying degrees of success. After review of these modalities, a treatment plan was devised and implemented.

The treatment of chronic incisional pain and headache after retromastoid craniectomy.

Background: A seldom emphasized complication of retromastoid craniectomy is chronic postcraniectomy incisional pain or headache. Although hypotheses have been proposed to explain this problem, there have been few attempts to treat patients in a delayed fashion. The results of postoperative treatments for chronic postretromastoid craniectomy pain and their rationales are discussed in a preliminary number of patients.

The surgical management of chronic cluster headache.

Objective: Chronic cluster headache occurs in less than 10% of cluster headache sufferers, but remains an intractable medical problem. Surgical treatments have also been limited in their effectiveness. The authors describe their experience with attempted surgical amelioration of chronic cluster headache.

Cutaneous-evoked tinnitus. II. Review Of neuroanatomical, physiological and functional imaging studies.

Cutaneous-evoked tinnitus is a clinical entity that has not been reported previously in the neurootological literature. Herein, a neuroscience framework that encompasses several distinct areas of research is used to conceptualize and help understand this phenomenon. We review normal neuroanatomical and physiological interactions between auditory and somatosensory systems in mammals.

Cutaneous-evoked tinnitus. I. Phenomenology, psychophysics and functional imaging.

DC00166e and acute unilateral deafferentation of the auditory periphery (auditory and vestibular afferents) can induce changes in the central nervous system that may result in unique forms of tinnitus. These tinnitus perceptions can be controlled (turned on and off) or modulated (changed in pitch or loudness) by performing certain overt behaviors in other sensory/motor systems. Clinical reports from our laboratory and several other independent sources indicate that static change in eye gaze, from a neutral head-referenced position, is one such behavior that can evoke, modulate and/or suppress these phantom auditory events.
