Bony reconstruction by reposition of bony chips in suboccipital craniectomy

In suboccipital craniectomy where the bone is not repositioned, there may be a significant cosmetic defect due to lack of skull bone in the suboccipital region. It may accompanied by sensory symptoms, including pain. To prevent any cosmetic defect and sensory symptoms we repositioned the bone chips at the craniectomy site in 42 suboccipital craniectomies before the closure of the scalp. At a mean follow-up of 22 months (range: 5-44 months), two patients complained of mild discomfort in the healed wound or of occasional local pain. One patient complained of mild itching at the site. In two patients, bone chips were accumulated at the lower part of the suboccipital craniectomy and failed to form a uniform bone cover at the operated site. In one patient, all bone chips were reabsorbed and there was no bone at the operated site. There was pseudomeningocele formation in one patient. In the rest of the cases there was satisfactory bone coverage at the operated site, both clinically and radiologically. The wound sites were aesthetically acceptable in 40 cases. Our study suggests that in the majority of cases where suboccipital craniotomy is not possible or not done, repositioning of the bone chips at the craniectomy site is associated with satisfactory aesthetic and functional outcome and formation of bone coverage at the operated site
