Effect of Craniotomy on Temporalis Function

No results posted yet for this study

Summary

The scientific objectives of this study are to systematically study the problems that are created by incising the attachment of the temporalis muscle in a randomized group of patients, and to determine whether another approach that does not detach the temporalis muscle results in less post-operative morbidity. Cutting through the attachment of the temporalis muscle to the skull is a widely-accepted procedure used to gain access to the skull prior to the drilling used for a pterional craniotomy (one of the most frequent types of surgeries used in neurosurgical practice). Despite the frequent use of this maneuver and the known sequelae of temporalis mobilization (e.g. post-operative myofascial pain, temporalis weakness, and pain with mastication), very little is known about the true incidence of these post-operative symptoms. Furthermore, there is very little objective evidence at the present time to support the claim that the incidence and severity of these post-operative phenomena can be decreased with use of an osteoplastic craniotomy (a procedure where the temporalis is left attached to the bony calvarium). The investigators would like to evaluate whether this slightly more time-consuming and technically demanding approach is less morbid in this respect than the contemporary pterional approach. Special note is made that the osteoplastic approach has been used in standard neurosurgical practice for quite some time.

Conditions

  • Pterional Craniotomy

Interventions

PROCEDURE

Traditional pterional craniotomy

In the standard pterional craniotomy group, the attachment of the temporalis will be cut and the temporalis will be mobilized prior to exposure of the underlying bony calvarium. This maneuver is currently accepted for use by the majority of neurosurgeons nationwide.

PROCEDURE

Osteoplastic craniotomy

In the osteoplastic group, the temporalis will be left attached to the bony calvarium prior to exposure of the tumor. There are ways to turn a bone flap with the temporalis still attached (i.e., an "osteoplastic craniotomy"). However, this method is thought to be slightly more time-consuming and is used less often in many centers. Aside from the extra time involved, we do not feel that leaving the temporalis attached to the bony calvarium disadvantages the patient in any fashion and may--in fact--result in less post-operative morbidity.
