A spinal extradural arachnoid cyst (SEAC) results from a rare small defect of the dura matter that leads to cerebrospinal fluid accumulation and communication defects between the cyst and the subarachnoid space. There is consensus for the treatment of the dural defect, but not for the treatment of the cyst. Some advocate a total resection of the cysts and repair of the communication site to prevent the recurrence of a SEAC, while others recommended more conservative therapy. Here we report the outcomes of selective laminectomy and closure of the dural defect for a 72-year-old and a 33-year-old woman. Magnetic resonance imaging of these patients showed an extradural cyst from T12 to L4 and an arachnoid cyst at the posterior epidural space of T12 to L2. For both patients, we surgically fenestrated the cyst and repaired the dural defect using a partial hemi-laminectomy. The patient’s symptoms dramatically subsided, and follow-up radiological images show a complete disappearance of the cyst in both patients. Our results suggest that fenestration of the cyst can be a safe and effective approach in treating SEACs compared to a classical complete resection of the cyst wall with multilevel laminectomy.

OBJECTIVETo compare the effect of small fenestra stapedotomy and total stapedectomy in patients with otosclerosis.

METHODSTwenty-seven patients (30 ears) undergoing small fenestra stapedotomy and 36 patients (43 ears) receiving total stapedectomy were compared for hearing results and complication rates.

RESULTSNo statistically significant differences were seen in postoperative speech pure tone average in closing air-bone gap between the two groups. The ears treated by small fenestra stapedotomy showed statistically better air-bone gap closure at high frequencies with lower rates of sensorineural hearing loss at high frequencies and milder dizziness.

CONCLUSIONIn spite of the successful hearing outcomes in both groups, small fenestra stapedotomy can achieve better results at high frequencies and reduce the incidence of complications.

OBJECTIVETo compare the effects of small fenestra stapedotomy with semiconductor diode laser and microdrill in patients with otosclerosis.

METHODSTwenty-six patients (29 ears) undergoing stapedotomy with semiconductor diode laser and 19 patients (21 ears) with microdrill were compared for the hearing results and complication rates.

RESULTSNo statistically significant differences were found in postoperative speech frequency and high frequency pure tone average in closing the air-bone gap between the two groups. The ears treated by stapedotomy with semiconductor diode laser showed significantly better preoperative minus the postoperative air-bone gap and milder dizziness.

CONCLUSIONIn spite of the good hearing outcomes in both groups, small fenestra stapedotomy with semiconductor diodelaser can achieve better results and reduce the incidence of complications.
