Although moderate amounts of pneumocephalus can be easily identified on routine skull films, very small amounts of air can be easily diagnosed and its location correctly assessed only by computerized tomography. The identification of even a small air collection should alert the clinician to the likelihood of a basilar skull fracture and its potentially serious sequelae such as tension pneumocephalus or meningitis. Authors report and summarize 11 cases of traumatic peumocephalus diagnosed with CT scan.

Most posttraumatic cerebrospinal fluid (CSF) leakage is noticed by the patients with the first symptom, rhinorrhea. A 38-year-old woman presented with frequent clear continuous rhinorrhea and otorrhea for 5 years after basilar skull fracture. After this, meningitis was developed with subsequent CSF fistula. Her clinical symptom was improved by medical treatment. The dural defect and CSF leakage were not detected by computerized tomography (CT) cisternography. We report a rare case of persistent posttraumatic CSF fistula that continued for five years.

Objective: To describe a makeshift blue light filter for endoscopic visualization of a traumatic cerebrospinal fluid leak repair using intrathecal fluorescein and its application in one patient. Methods: Study Design:Surgical Instrumentation Setting:Tertiary Government Training Hospital Patient:One Results: Intra-operative endoscopic identification of fistulae sites was achieved using intrathecal injection of fluorescein that fluoresced using our makeshift blue light filter in a 43-year-old man who presented with a 3-month history of rhinorrhea due to skull base fractures along with multiple facial and upper extremity fractures he sustained after a fall from a standing height of 6 feet. He underwent transnasal endoscopic repair of cerebrospinal fluid fistulae in the planum sphenoidale, clivus and sellar floor. Post-operatively, there was complete resolution of rhinorrhea with no complications noted. Conclusion Our makeshift blue light filter made from readily available materials may be useful for endoscopic identification of CSF leaks using fluorescein in a low- to middle-income country setting like ours.

188 consecutive cases with basilar skull fractures(BSF) out of 2676 head injury patients who were treated in Chung-Ang Gil Hospital from July 1993 to June 1995, were analyzed. These fractures are difficult to diagnose by ordinary X-ray examinations, routine head computed tomography(CT) and are frequently inferred by clinical signs. Therefore, it's diagnosis is somtimes delayed or missed in initial assessment of trauma patients. They are different from cranial vault fractures in several aspects other than difficulties in the diagnosis. It involves more commonly the cranial nerves(CN), makes cerebrospinal fluid(CSF) fistulae and leads to central nervous system(CNS) infections if the CSF fistulae are not detected or treated early and properly. The authors reviewed the clinical features, radiological findings, rate of delayed diagnosis, complications and outcomes. The most common feature of BSF was otorrhea(64.4%) and followed by rhinorrhea(39.4%), raccoon eye(32.4%) and hemotympanum(24.5%). In only 6.4% of cases, the fracture lines were detected by ordinary skull radiographs and diagnosed as BSF. In contrast, the high resolution skull base CT confirmed the fractures in 62.2%. Clinical diagnoses were made in 14.9%. Commonly combined craniofacial lesions were cranial vault fractures(51.1%), intracranial hemorrhages(46.3%), and facial bone fractures(34.0%). Most of CSF leakages(89.7%) were noted within 24 hours after injury and most of the leakages (87.7%) had ceased by conservative management within 2 weeks, but 5.1% that did not respond to conservative treatment and lumbar CSF drainage, needed invasive operative repair. The incidence of meningitis was 3.2% and the prophylactic antibiotics had no benificial effect on lowering the infection rate. Facial nerve was the most frequently involved cranial nerve followed by vestibulo-cocchlear, oculomotor, and olfactory nerve in decreasing order of frequency. The onset of facial palsy was immediate in 31.8% and the remainder were delayed more than 24 hours after head injury. Of 188 patients, 21 cases(11.2%) were delayed in the diagnosis of BSF.

We report a 57-year-old man with bilateral cranial nerve IX and X palsies who presented with severe dysphagia. After a mild head injury, the patient complained of difficult swallowing. Physical examination revealed normal tongue motion and no uvular deviation. Cervical X-ray findings were negative, but a brain computed tomography revealed a skull fracture involving bilateral jugular foramen. Laryngoscopy indicated bilateral vocal cord palsy. In a videofluoroscopic swallowing study, food residue remained in the vallecula and pyriform sinus, and there was reduced motion of the pharynx and larynx. Electromyography confirmed bilateral superior and recurrent laryngeal neuropathy.
