Objective: To study the influence of cervical settling method on marginal accuracy of wax patters.
Methods: 24 wax patterns were made on the standard cast specimens and round capsules of which twelve patters were made with the method of cervical settling (experiment group), twelve patters were made with the method of wax dripping (control group). Marginal accuracy of patterns were measured before sublation, sublation half an hour and twenty-four hours.
Results: The results revealed that marginal accuracy had significant difference between the cervical settling methods and wax dripping methods (P < 0.05). There was significant difference between the cervical settling methods measured after half an hour and twenty-four hours (P < 0.01). There was also significant difference between the wax dripping methods measured after half an hour and twenty-four hours (P < 0.01).
Conclusion: Wax patterns with the method of cervical settling can improve marginal accuracy of patterns. The marginal accuracy of wax patters are influenced by the existing time.

Background: Giant prolactinoma (size > 4 cm) is a rare condition and accounts for less than 1% of pituitary adenomas. In even rarer cases, these lesions may involve craniocervical structures requiring surgical intervention. The present case is the largest reported giant prolactinoma (99 × 72 × 57 mm).

Introduction: Death is the most common outcome of longitudinal atlanto-occipital dissociation (L-AOD). Even though rare, survival is commonly seen in the pediatric population. This study reports a successful outcome of a pediatric patient with an L-AOD without neurodeficits, immobilized in a visor (head-neck-chest) orthosis.
