Purpose
To determine the incidence and risk factors of postoperative infection after cranioplasty in patients with traumatic brain injury (TBI).
Methods
Data of 289 adult patients who underwent cranioplasty after TBI at a single regional trauma center between year 2018 and 2021 were reviewed retrospectively. Patient characteristics and various procedural variables, such as interval between craniectomy and cranioplasty, estimated blood loss, laterality and materials of the bone flap, and duration and classification of perioperative antibiotics usage were analyzed.
Results
Postoperative infection occurred in 17 patients (5.9%). Onset time of infectious symptom ranged from 9 days to 174 days (median, 24 days) after cranioplasty. The most common cultured organism was Staphylococcus aureus (47.1%), followed by Klebsiella pneumoniae (17.6%) and Enterococcus faecalis (17.6%). Patients with postoperative infection were more likely to have diabetes (odds ratio [OR], 6.96; 95% confidence interval [CI], 1.92–25.21; P=0.003), lower body mass index (OR, 0.81; 95% CI, 0.66–0.98; P=0.029), and shorter duration of perioperative antibiotics (OR, 0.83; 95% CI, 0.71–0.98; P=0.026).
Conclusions
For TBI patients with diabetes, poor nutritional status should be managed cautiously for increased risk of infection after cranioplasty. Further studies and discussions are needed to determine an appropriate antibiotics protocol in cranioplasty.

AbstractAbstract PDF
Craniocerebral gunshot injuries is gradually increasing in the civilian population with a worse prognosis than closed head trauma. We experienced a case of craniocerebral gunshot injury which a bullet penetrating from the submandibular area into the clivus of a patient. The patient did not show any symptom. However, serial laboratory findings showed an increase in blood lead level. We removed foreign bodies without any problems using an endoscopic transnasal transclival approach. Due to the extremely low frequency, guidelines for definitive management of gunshot injuries have not been presented in Korea yet. We introduce our surgical experience of a craniocerebral gunshot injury with an unusual approach for removing intracranial foreign bodies.

Purpose

Trauma incidence and hospitalizations of trauma patients are generally believed to be affected by season and weather. The objective of this study was to explore possible associations of the hospitalization rate of trauma patients with weather and time variables at a single regional trauma center in South Korea.

Methods

Trauma hospitalization data were obtained from a regional trauma center in South Korea from January 1, 2017 to December 31, 2019. In total, from 6,788 patients with trauma, data of 3,667 patients were analyzed, excluding those from outside the city where the trauma center was located. Hourly weather service data were obtained from the Korea Meteorological Administration.

Results

The hospitalization rate showed positive correlations with temperature (r=0.635) and wind speed (r=0.501), but a negative correlation with humidity (r=−0.620). It showed no significant correlation (r=0.036) with precipitation. The hospitalization rate also showed significant correlations with time of day (p=0.033) and month (p=0.22).

Conclusions

Weather and time affected the number of hospitalizations at a trauma center. The findings of this study could be used to determine care delivery, staffing, and resource allocation plans at trauma centers and emergency departments.

AbstractAbstract PDF
Purpose

Cranioplasty itself is believed to have therapeutic effects on hydrocephalus. The goal of this study was to evaluate the hypothesis that not every patient with hydrocephalus after decompressive craniectomy needs cerebrospinal fluid diversion, and that cranioplasty should be performed before considering cerebrospinal fluid diversion.

Methods

Data were collected from 67 individual traumatic brain injury patients who underwent cranioplasty between January 1, 2019 and December 31, 2019. Patients’ clinical and radiographic progression was reviewed retrospectively based on their medical records.

Results

Twenty-two of the 67 patients (32.8%) had ventriculomegaly on computed tomography scans before cranioplasty. Furthermore, 38 patients showed progressive ventriculomegaly after cranioplasty. Of these 38 patients, only six (15.7%) showed worsening neurologic symptoms, which were improved by the tap test; these patients eventually underwent ventriculoperitoneal shunt placement.

Conclusions

Cerebrospinal fluid diversion is not always required for radiologically diagnosed ventriculomegaly in traumatic brain injury patients after decompressive craniectomy. A careful clinical and neurologic evaluation should be conducted before placing a shunt.

AbstractAbstract PDF
Purpose

The purpose of this study was to determine the incidence and characteristics of associated injuries in patients with spine trauma.

Methods

Data of 3,920 consecutive patients admitted to a regional trauma center during a 3-year period were analyzed retrospectively.

Results

Of the 3,920 patients who were admitted to the trauma center during the 3-year study period, 389 (9.9%) had major spinal injuries. Among these 389 patients, 303 (77.9%) had associated injuries outside the spine. The most common body region of associated injuries was the extremities or pelvis (194 cases, 49.4%), followed by the chest (154 cases, 39.6%) and face (127 cases, 32.6%). Of these 303 patients, 149 (64%) had associated injuries that required surgical treatment such as laparotomy or internal fixation. Associated injuries were more common in patients with lumbar injuries (93.3%) or multiple spinal injuries (100%) than in those with lower cervical injuries (67.4%). There was a significant correlation between the location of the spinal injury and the body region of the associated injury. However, distant associated injuries were also common.

Conclusions

Associated injuries were very common in spinal injury patients. Based on demographic groups, the trauma mechanism, and the location of spinal injury, an associated injury should be suspected until proven otherwise. Using a multidisciplinary and integrated approach to treat trauma victims is of the paramount importance.
