Approximately 6 months later, the toucan was presented for the recommended sinus trephination
and sinoscopy procedure.
Rasping, shaving, trephination
, and synovial fold abrasion should be used liberally and aggressively to enhance the healing potential of the repair.

and the art of medicine in ancient Peru.
Furthermore, there have been a lopsided number of cases of trephination
for subdural hematomas.
Incision and trephination
were performed; pathologic examination after orthopedic intramedullary placement is shown in Figure 5.
Based on carbon-14 dating, the oldest example of trephination
was discovered in the Ukraine and is dated as 7300 B.C., while a carbon-14 study from France has reported skulls trephined in 5100 B.C.
of the skull to allow advancement of the vascular supply from the meninges to the granulation bed of the dorsal skull.
By pulling the torn flaps peripherally and skipping the trephination
stage of the graft preparation technique described by Melles et al., (3,4) these irregular-edged grafts can still be successfully implanted.
Chronic subdural hematoma (CSDH) is one of the most common clinical entities encountered in daily neurosurgical practice.1-5 The incidence of CSDH has been reported to be as high as 13.1 cases per 100000 inhabitants.6 The condition is treated by various surgical procedures including burr-hole trephination
, twist-drill trephination
and craniotomy.7-10 Of these procedures, burrhole evacuation is the most popular technique worldwide.1,6,7 However, considerable recurrence rates have been reported ranging from 3 to 30% following surgical management.7,9,11,12
Furthermore, needling, rasping, or trephination
to promote vessel ingrowth into damaged meniscus by puncturing healthy tissue is frequently and successfully used in meniscus surgery [75, 76].
