Background:
The aesthetic reconstruction of disfiguring cranio-facial defects after tumour excision can be quite challenging to the neurosurgeon with limited resources. The choice of cranioplasty implant, intraoperative technicalities and the patients' postoperative appearance are critical considerations in management. There are a number of synthetic materials available for cranioplasty, however, the customised implants are not readily available in our practice setup. They are also mostly constructed and contoured after the bony defect has been created or require sophisticated software construction pre-operatively.
Methods:
Eight patients with cranio-facial tumour pathologies who presented to our neurosurgical service, and had titanium mesh cranioplasty for the correction of cosmetically disfiguring cranio-facial tumours.
Results:
There were 6 females, and 2 male patients respectively, with an age range between 28 and 74years. The histological diagnoses were meningioma, frontal squamous cell carcinoma, fibrous dysplasia, frontal mucocoele, cemeto-ossifying fibroma, osteoma, and naso-ethmoidal squamous cell carcinoma. The patient with naso-ethmoidal squamous cell carcinoma had post-operative subgaleal empyema which was amenable to incision and drainage procedure. The patient with a frontal cemento-ossifyng fibroma had a transient immediate post-operative mechanical ptosis, which resolved completely in 3months. All of the total eight patients (100%) had satisfactory cosmetic outlook at a minimum follow up period of 1month post-operatively (Numeric Rating Scale of at least 7/10). One of the patients required a revision surgery on account of implant displacement.
Conclusion:
Cranioplasty is a common reconstructive neurosurgical procedure. It is important to the neurosurgeon for its neuro-protective function, and in the restoration of intra-cranial CSF dynamics. However, the cosmetic outlook appears to be more important to patients in the absence of pain and/or neurological deficits. Titanium mesh reconstruction is commonly used globally, and is becoming the preferred choice in low resource settings.
