Cost effective and fast craniotomy in Meningiomas.

Trephine craniotomy is the fastest way to open the cranium. Trephine can be made almost on any part of skull. William B Scoville was a pioneer in practicing trephine craniotomy. His visit to Vellore in India around 1964 was instrumental in introducing trephine craniotomy. Author has made trephine craniotomy very safe and cost effective with introduction of adjustable dura guard. In more than 90 percent of cases author uses trephine craniotomy.

Meningioma in a middle aged female operated by trephine craniotomy in April 2010 in Korean Hospital, Addis Ababa. 8. Picture of Karam Chand trephine with adjustable dura guard. The trephine is available in various diameters.
Even for acoustic tumours and other posterior fossa tumours author routinely uses trephine craniotomy.

Above 3 images are of a young lady who was operated for right temporal meningioma on 8/11/2010. A right temporal trephine craniotomy was made using 5.25 cm Karam Chand trephine having adjustable dura guard. A quick and safe craniotomy was done without any injury to underlying dura. The meningeal arteies were under-run with 3,0 vicryl and obliterated before opening dura. Complete excision was done, good haemostasis was achieved with surgiflo(from Johnson and Johnson), trephined bone was replaced after applying hitch sutures.

I have posted pictures of a patient operated for right temporal meningioma. A quick 5.25 cm trephine craniotomy was done. Surgiflo achieves very good haemostasis.

I tend to use Scoville's trephine in epidurals and in small tumours. I would be interested to know the diameter ot Dr Chand's trephine and where to order it from. I presume it uses a centering drill?

The trephine is available in 1.5 t0 5.25 cm diameter. My trephine has adjustable dura guard. !.5 cm and 2.0 cm trephines need central removable pin to make a groove but in my experience 4cm and 5.25 cm trephine do not need central pin, although again detachable pin is supplied with it. Special scalp retractor developed by me provides excellent exposure after straight scalp incisions. For trephine and retractor please contact and also you can search on google- avm healthcare delhi and fourbhai udyog delhi. See you sometime in Mexico.
