[Clinical analysis of brain abscess after endoscopic repairment of cerebrospinal fluid rhinorrhea].

Objective

To explore the clinical characteristics of the complication of brain abscesses after cerebrospinal fluid rhinorrhea repairment.

Methods

A retrospective analysis was conducted on 149 patients undergone endoscopic repairment of cerebrospinal fluid rhinorrhea from October 2007 to October 2017 in Department of Otorhinolaryngology Head and Neck Surgery, Tianjin HuanHu Hospital. The clinical characteristics and treating methods of 3 brain abscess cases were analyzed.

Results

Of the 149 patients accepted the endoscopic repairment of cerebrospinal fluid rhinorrhea, 3 cases were complicated with postoperative brain abscesses, which showed as frontal lobe abscess by strengthened head MRI. The incidence of abscess was 2.0%. Abscess formation time was within 10 d after surgery. One case was treated with antibiotic and reducing intracranial pressure, while other 2 cases were treated with puncture drainage. After following-up of 1 to 24 months, these 3 cases had no recurrence of cerebrospinal fluid rhinorrhea or abscess.

Conclusions

The complication of brain abscess formation after endoscopic repairment of cerebrospinal fluid rhinorrhea is more common in frontal lobe, which may take place within 7-10 d postoperatively. Conservative treatment is the first choice. Under the condition of obvious symptoms and pus cavity fusion, puncture drainage can be performed.
