The role of craniotomy and trephination in the treatment of chronic subdural hematoma.
The treatment of chronic subdural hematoma by craniotomy was the procedure of choice in the early part of this century. It has since been replaced by less invasive techniques but retains a limited role in the management of this condition. A new procedure involving a small craniectomy and marsupialization of the hematoma cavity to the temporalis muscle is described. The results of this treatment compare favorably with the more commonly performed drainage methods.

An overview of chronic subdural hematoma: experience with 2300 cases.
BACKGROUND: Over a period of 30 years since 1966, 2300 cases of chronic subdural hematoma have been seen and treated. DESCRIPTION: A male preponderance among the cases was seen, in a ratio of 5:1. The condition presented with various manifestations. Nine hundred were seen in the pre-CT period (before 1980), compared to 1400 cases encountered after 1980. Since 1968, these cases have been managed by a small temporal craniotomy, with the dura left open and the subdural space communicating with the subtemporalis area. CONCLUSION: This procedure has resulted in marked reduction of recurrence, and membranectomy has not been required. There have been 11 deaths in this group of patients; the mortality rate is only 0.5%.

Giant cell reparative granuloma of the craniofacial complex: case report and review of the literature.
Giant cell reparative granuloma (GCRG) is an infrequent non-tumoural lesion affecting particularly the maxillary and mandibular bones and only rarely the cranial bones. The pathogenesis is still controversial and the differential diagnosis, especially from giant cell tumours of bone, is difficult. A case of GCRG of the sphenoid masquerading as an intracranial tumour is reported here. The relevant literature is reviewed.

Epidermoid cyst of the pineal region.
An epidermoid cyst in the pineal region is reported to underscore the feasibility of successful surgical excision of such lesions and the need to review the management of posterior third ventricular lesions. An interesting, but unexplained, feature in this patient was renal glycosuria which cleared after excision of the tumour.
Uniocular proptosis in children.
A retrospective study on 80 children with uniocular proptosis has been done. Of these 57 had orbital lesions, 19 had periorbital lesions and 4 had intracranial lesions. The clinical, radiological and pathological aspects as well as the management of these conditions are discussed.
