| Young prostatic tractor | A short, straight tubular instrument with blades at its tip, which can be rotated open and closed; it is passed into the prostatic urethra, through a prostatotomy incision made during the later stages of open perineal prostatectomy, with its tip into the bladder; direct traction on the instrument brings the prostate gland down into the operative field where enucleation can be more easily performed. (05 Mar 2000) |
| Lowsley tractor | A slender curved instrument with flexible blades at its tip, which can be opened or closed by rotation at the proximal end of the tractor; it is passed per urethram into the bladder and used to retract the prostate gland downward into the operative field in the initial stages of perineal prostatectomy.

| basal skull fracture | <orthopaedics> A fracture involving the base of the cranium. This fracture is often difficult to detect clinically. Findings may include raccoon eyes, Battle's sign, haemotympanum and cerebrospinal fluid rhinorrhoea. Plain skull X-ray will often not reveal the basal skull fracture, making a CT scan or MRI the most reliable diagnostic investigation. (15 Nov 1997) |
| base of skull | The sloping floor of the cranial cavity. It comprises both the external base of skull (external view) and the internal base of skull (internal view). See: internal base of skull. Synonym: basis cranii, cranial base. (05 Mar 2000) |
| bones of skull | The paired inferior nasal concha, lacrimal, maxilla, nasal, palatine, parietal, temporal, and zygomatic; and the unpaired ethmoid, frontal, occipital, sphenoid, and vomer. Synonym: ossa cranii, cranial bones. (05 Mar 2000) |

| closed skull fracture | Fracture with intact overlying scalp and/or mucous membranes. Synonym: simple skull fracture. (05 Mar 2000) |
| cloverleaf skull | <syndrome> Intrauterine bone dysplasia and synostosis of the coronal and lambdoid sutures producing a trilobar head shape, due to premature fusion (craniosynostosis) of all sutures. This produces various craniofacial and long-bone anomalies. The condition is sporadic; no evidence to suggest a genetic cause although there may be some hereditary in Crouzon syndrome.
