The cephaloceles: A clinical, epidemiological and therapeutic study of 50 cases

INTRODUCTION

Cephaloceles are congenital malformations characterized by externalization of the meninges and/or brain tissue through a congenital skull bone defect. In developed countries, this malformation is rare but in our developing countries, this pathology remains one of our concerns.

OBJECTIVE

To describe the epidemiological, clinical and therapeutic aspects of the cephaloceles.

MATERIALS AND METHOD

A retrospective study was conducted from 2007 to 2013 on all cases of cephalocele supported in the department of neurosurgery of the Yalgado Ouédraogo University Teaching Hospital of Ouagadougou. The malformations were supplemented by CT scan. All patients were operated. The surgical procedure in cephaloceles of the convexity consisted of a direct approach. Sincipital cephaloceles were operated by transcranial approach or combined approach associating transcranial and transnasal approaches.

RESULTS

Fifty patients were gathered during the 7-year period. There were 18 boys and 32 girls. The ages ranged from 1 day to 11 years. The cephaloceles were located on the vault of the skull in 78%; the lesion was sincipital in 22%. The malformation was covered with normal skin in 92%; it was pediculated in 78%. CT scan allowed the classification of cases as meningo-encephaloceles in 31 cases (62%) and meningoceles in 18 cases (36%) and one pure encephalocele. The immediate postoperative course was uneventful in 42 cases (84%); 8 postoperative deaths were recorded. At medium and long term, 4 patients (8%) developed complications of psychomotor deficiency in 3 cases and hydrocephalus in 1 case. The main reasons for the poor prognosis were superinfection, hydrocephalus and/or other brain malformations.

CONCLUSION

Cephaloceles remain relatively frequent in our practice. After surgery, mental failure and hydrocephalus can occur impairing the prognosis. The most suitable solution is a policy of prevention with folic acid treatment before and during pregnancy and following up adequate pregnancies.

Frontoethmoidal cephalocele: our experience of eleven cases managed surgically

INTRODUCTION

Frontoethmoidal or sincipital cephaloceles are congenital malformations characterized by externalization of the meninges and/or brain tissue through a congenital bone defect between the frontal and ethmoid bones. These sincipital cephaloceles are very infrequent. While in developed countries the measures taken have brought about virtually zero frequency of this pathology, in our work environment these measures are virtually nonexistent, so that frontoethmoidal cephaloceles remain one of our concerns.

AIM

To describe the particularity of the management of frontoethmoidal cephaloceles in our country.

METHODS

This was a retrospective study carried out between January 1, 2007 and June 30, 2013. It concerned all cases of frontoethmoidal cephaloceles managed in the Neurosurgery Department of the University Hospital of Ouagadougou.

RESULTS

A total of 11 patients (6 females and 5 males) were attended to in 6.5 years. The age of the patients ranged from 1 day to 12 years, and 8 patients (72.72%) were less than 4 months old; 1 case was diagnosed at antenatal ultrasound. Clinically, all cases consisted of congenital cephalic swelling of gradual increase. A CT scan was performed in all cases and an ultrasound of the associated mass was carried out in 2 cases. Transcranial approach was done for all patients with 3 patients having had an incision of the mass to reduce redundant skin. The immediate postoperative course was favorable in 10 cases; 1 death was observed by cerebrospinal meningitis. We noted 1 case of recurrence.

CONCLUSION

The surgical treatment of frontoethmoidal cephaloceles is complex, sometimes requiring a multidisciplinary team. However, early closing of the malformation before the appearance of important bone deformities can prevent maxillofacial surgery. The results of the surgery are satisfactory as regards the vital prognosis. However, the fear of a more or less long-term occurrence of psychomotor retardation and the complications of early surgery make the recommendation and emphasis of prevention our main concern.
