AbstractIntroduction:Nasal dermoid cysts are congenital lesions which are often diagnosed in infancy or childhood. However, a small number present in adulthood, and some extend intracranially. Traditional treatment for the intracranial portion of these cysts includes frontal craniotomy.Case reports:Two intracranial dermoid cysts were resected via a transnasal endoscopic approach, using 70° nasal endoscopy for complete visualisation and intracranial tumour removal. We describe our technique for the procedure itself and for reconstruction of the skull base defect.Discussion and conclusion:The endoscopic transnasal skull base approach is an excellent alternative to a traditional frontal craniotomy, to achieve complete resection of intracranial dermoid cysts.

AbstractObjective:We report the use and benefits of the ultrasonic dissector in the resection of difficult skull base lesions.Method:Five case reports are presented, and the utilisation of ultrasonic dissectors in otorhinolaryngology is reviewed.Results:The ultrasonic dissector was found to be a useful tool during the endoscopic resection of poorly accessible skull base tumours. Safe dissection and complete removal of all five lesions were achieved without any vascular injury. To our knowledge, this is the first report of the use of the ultrasonic dissector for the resection of sinonasal and skull base tumours.Conclusion:The ultrasonic dissector was found to be particularly useful during the endoscopic transnasal approach to the petrous apex. During minimally invasive endonasal surgery, benefits include the length of the instrument, speed and precision of dissection, and low risk of vascular injury.

AbstractBackground:Glomangiopericytoma is a rare sinonasal tumour of perivascular myoid phenotype, which accounts for less than 1 per cent of all sinonasal tumours.Objective:Discussion of the clinical presentation, histopathological features and advances in the management of sinonasal and skull base glomangiopericytoma.Case report:A 32-year-old woman presented with worsening nasal obstruction, anosmia, severe frontal headaches and right-sided proptosis. Radiographic and endoscopic examination revealed a right-sided, vascular mass involving the nasal cavity, paranasal sinuses and anterior skull base. Histopathological features were consistent with a glomangiopericytoma. Complete endoscopic resection with free margins was achieved.Conclusion:Glomangiopericytomas are rare, vascular, sinonasal tumours. Successful management depends on complete resection, traditionally achieved via an open approach. However, recent advances in endoscopic surgical approaches have enabled complete endoscopic resection of these tumours, minimising morbidity and facilitating subsequent surveillance of the operative site.

Cavernous Hemangiomas

Sinonasal hemangiomas, although rare, must be considered in the evaluation of intranasal masses with profuse epistaxis. Although the availability of literature discussing cavernous hemangiomas in this location is limited, there have been no case reports of exclusively soft tissue sinonasal cavernous hemangiomas extending to the anterior skull base (ASB) that were resected purely endoscopically. Here, we describe the successful endoscopic resection of an extensive right sinonasal cavernous hemangioma extending to but not invading the ASB. Although highly vascular, in select cases, these tumors can be successfully resected endoscopically without embolization by experienced endoscopic sinus and skull base surgeons.

Skull Base Defects

Object The object of this study was to assess the efficacy and complications of endoscopic management of anterior skull base defects. Method The authors reviewed the medical records of 28 children (20 boys and 8 girls) undergoing endoscopic repair of anterior skull base defects in their tertiary referral center between 2001 and 2008; 18 cases were congenital and 10 cases posttraumatic. During the endoscopic procedure, rigid telescopes—2.7 or 4 mm in diameter, with 0° or 30° lenses—were used. In 23 patients the anterior skull base defect was sealed with fragments of middle turbinate (bone and mucosa). In the remaining 5 patients it was sealed with cartilage harvested from the nasal septum (3 cases) or from the auricle (2 cases), fibrin glue, and oxidized cellulose. A combined external and endoscopic approach was required in 3 cases because of the size and extensions of the encephalocele. Outcome was primarily assessed by means of clinical examination, nasal fibroscopy, and imaging. Results The mean duration of follow-up was 26.7 months (range 9–57 months). One patient treated by a combined approach died of meningitis 2 years after surgery. In the remaining 27 patients, there was no recurrence of CSF leak, meningitis, or encephalocele. An iatrogenic frontal or ethmoidal mucocele was observed in 4 cases. Conclusions The endoscopic approach is a minimally invasive, safe, and efficient technique for removing nasal encephaloceles in children.
