鼻内镜下Draf Ⅱ-Ⅲ型额窦开放手术在颅脑外伤术后反复额窦感染并窦道形成中的应用OACSTPCD

OBJECTIVE To investigate the application of endoscopic Draf Ⅱ-Ⅲ frontal sinus surgery in the treatment of recurrent frontal sinus infection and fistula formation after craniocerebral trauma.METHODS There were 8 cases of recurrent frontal sinus infection after craniocerebral trauma,the main manifestations were headache,recurrent frontal infection,discharge of pus,fistula formation.The average onset time was 43.25 months.The patients underwent DRAF Ⅱ-Ⅲ frontal sinus surgery under nasal endoscopy,including Draf Ⅱa 2,Draf Ⅱb 5,and Draf Ⅲ1,respectively.During the operation,the frontal sinus ostium was expanded.It was found that bone wax blocked the frontal sinus ostium in the frontal sinus.The bone wax was removed,and the frontal sinus drainage was smooth.No facial incision was made in all patients.RESULTS There were 8 patients with frontal infection who were cured after surgery.No cerebrospinal fluid rhinorrhea or intracranial infection occurred during or after operation.After discharge,the outpatient follow-up review was conducted in 1,3,6,and 12 months.It was found that the frontal sinus remained unobstructed.The frontal sinus did not become infected again,and the fistula gradually healed.CONCLUSION Draf Ⅱ-Ⅲ frontal sinus surgery under nasal endoscopy is an effective way to treat recurrent frontal sinus infection and fistula formation after craniocerebral trauma.
