“…He also developed instruments for the endoscopic division of the sensory roots of the nerve (Doyen, 1917). In the late 1940s and early 1950s, the development of a coherent fiber optic bundles for image transmission, and an incoherent bundle for light transmission by Hopkins greatly aided the improvement of endoscopes that are used in modern surgical practice (Prott, 1974, Griffith, 1975, Mer et al 1967. Later on the endoscopic anatomy of the cerebellopontine angle via translabyrinthine end retrosigmoid approach was described in detail by Prott and Opel (Prott, 1974, Opel, 1974, 1981, O´Donough et al 1993).…”

Telescopic Examination of the mastoid Cavity

,4_bs~ctOtoendoscopy enables viewing of different angles of the tympanomastoid area and approach to them for better prognosis. A comparative study of post-operative mastoid cavities has been done using the Hopkin's rod telescope, Otoscope and microscope. Variousprocedures have also been done successfully on the mastoid cavity using the telescope on an outdoor basis.A l t h o u g h mastoidectomy operations have been done for over 200 years now, postoperative mastiod cavities still present much problem to both the patient and the surgeon. Smith M. F. N. (1981) stated that 'deafness, discharge, dizziness, and dependancy partially definethediscomfortsofpatientswith an open draining mastiod cavity' basing his report on an out-patient and surgical managemnt of more than 300 than open draining mastiod cavities.After radical and modified radi-cal mastoidectomy, the cavity must be followed to detect any recurrent or residual disease, infections etc. Modem optical technology has made available fibreoptic rigid telescopes. Exploration of the middle ear can now be accomplished by the use of endoscopic techniques. Endoscopes with small diamaters and wide fields of view provide extraordinary visualization of the middle ear which was previously accessible only by surgical means.The use of endoscopes for the middle ear was first described by Mer et al. (1967) who used a fibreoptic system delivered through existing tympanic membrane perforations in two patients. Eichner (1978) popularized rigid endoscopes for improved resolution.Endoscopy of the middle ear has been previously used as an adjunct to microscopic examination in the office (Baltany, 1990). RE Ahmad (1994) has described the successful use of 30 fibreoptic Hopkins rod telescope for the post-operative follow-up of the mastiod cavity with gratifying results. M a t e~a l a n d M e t h o d sThe present study was undertaken in the Dept. of E. N. T. S. M. S. Hospital, Jaipur on 25 cases of operated mastoidectomy. A detailed history and clinical examination of the patients were carried out.The mastoid cavity was inspected for the presence of cholesteatoma, desquamated debris, granulations, recurrent and residual disease. These were removed from the cavity under endoscopic control. Exuberant granulations were cauterized with silver nitrate. In cases of delayed epithelialization, the growth of epithelium was stimulated by the application of gentian violet. Foreign bodies were removed from the cavity under telescopic control. High buttresses and facial ridge were curetted under guidance of the telescope. R e s u l t s25 post-mastoidectomy patients constituted the case material of this study.

“…endoscopic visualization of body areas pre viously untried became routine. The urological surgeons had used endoscopy for many years, but were quickly fol lowed by their general surgical [ 19], pediatric surgical [20] and gynecological colleagues [21], Interest in endoscopy grew in orthopedics [22], otorhinolaryngology [23,24] and cardiovascular surgery [25]. Visualization of the spi nal cord, conus and cauda equina became possible through a 'myeloscope' developed by Pool [26,27], In 1976, Sayers and Kosnik [28] reported on 40 cases of percutaneous ventriculostomy.…”

The History of Ventriculoscopy: Where Do We Go from Here?

1992

View full text Add to dashboard Cite

With the availability of better endoscopes, improved lighting and increased instrumentation, the use of ventriculoscopy and ventriculostomy in the management of hydrocephalus is becoming increasingly more common. Neurosurgeons recognized the potential for endoscopic surgery early in this century, but were frustrated in many of their attempts at treatment due to the poor quality of the instruments available. Nevertheless, much progress has been made, and the stage was set for better results with modern instrument design. This paper reviews the history of endoscopes in neurosurgery and ponders the direction these instruments will take us in the near future.
