ABSTRACT
OBJECTIVE: To study the prevalence and patterns of contrecoup injury in traumatic temporal bone fracture cases. METHOD: A prospective, cohort study was undertaken of all patients with traumatic head injury admitted to a tertiary referral hospital in Malaysia within an 18-month period. High resolution computed tomography scans of the brain and skull base were performed in indicated cases, based on clinical findings and Glasgow coma score. Patients with a one-sided temporal bone fracture were selected and subsequent magnetic resonance imaging performed in all cases. Contrecoup injury incidence, type, severity and outcome were recorded. RESULTS: Of 1579 head injury cases, 81 (5.1 per cent) met the inclusion criteria and were enrolled in the study. Temporal bone fractures were significantly associated with intracranial injuries (p < 0.001). The incidence of a contrecoup injury in cases with temporal bone fracture was 13.6 per cent. Contrecoup injury was significantly associated with petrous temporal bone fracture (p < 0.01). The commonest contrecoup injury was cerebral contusion, followed by extradural haematoma and subdural haematoma. CONCLUSION: Contrecoup injury is not uncommon in cases of temporal bone fracture, and is significantly associated with petrous temporal bone fracture.

Tonsillectomy is the single most common operation performed in Ear Nose and Throat Department. Various methods of tonsillectomy have been practiced over the century aimed at reducing or eliminating intraoperative and postoperative morbidity. Due to various blood supplies received, intraoperative bleeding is the most difficult problem and securing it is time-consuming. The time taken to control the bleeding would invariably determine the length of operation. Common postoperative complications are bleeding and pain. This study evaluated the operative time, intraoperative blood loss, postoperative pain and other postoperative complications of tonsillectomy performed by laser as compared to conventional dissection technique. This is a prospective randomized study whereby sixty patients were divided into two groups of equal number. In one group, the tonsillectomy performed by laser and in the other group the tonsillectomy performed by conventional dissection technique. Operative time and amount of blood loss is significantly reduced in the laser group. Total postoperative pain and post operative complications were not significantly different between the two groups. Tonsillectomy by using laser have shown less intraoperative bleeding and shortened the operative time. In the hospital where laser machine and expertise are available, it is justifiable to use this technique as effective method of performing tonsillectomy.
