To describe the clinical and radiological features of the vascular anomaly aberrant internal carotid artery (ICA) in the temporal bone and to discuss management strategies. Design: Retrospective study. Patients: Sixteen cases of aberrant ICA were diagnosed between 1982 and 2003. Results: Of 16 cases, 11 were recognized by imaging assessment, 4 were recognized during middle ear surgery, and 1 was recognized clinically. Among the 11 cases, 8 malformations were diagnosed because of otologic symptoms related to the abnormal ICA or chronic otitis, while the other 3 were identified incidentally because of an underlying accompanying disease. In 4 cases, the diagnosis was made during surgery related to chronic otitis media (n=2) or conductive hearing loss (n=2). In these 4 cases, massive bleeding resulted from surgical injury to the vessel. Packing the external auditory canal and the middle ear

The aim of this retrospective study was to compare clinical and radiological findings and discuss optimal surgical approach in patients with juvenile nasopharyngeal angiofibroma (JNA). Forty-three cases of JNA were treated at our institution from 1975 to 1999. Thirty-three male patients aged between 8 and 25 years (mean 15.3) were included. Twenty-nine patients underwent primary surgical treatment at our institution and four were treated for recurrence following primary surgery elsewhere. Tumors were staged according to Fisch's staging. Preoperative embolization was performed in 22 cases. Surgical techniques consisted of the transantral approach, lateral rhinotomy approach, transmaxillary via midfacial degloving approach, and the subtemporal preauricular infratemporal fossa approach. Tumors were classified stage I in seven cases, stage II in 11, stage III in 13 and stage IV in two. The mean delay between the initial symptom and surgery was 14 months overall, 18 months for stage I, 14 for stage II, 13 for stage III and 12 for stage IV. The transantral approach was used in 11 patients, lateral rhinotomy approach in 11 cases, transmaxillary via midfacial degloving approach in three patients, and pre-auricular infra-temporal approach in eight patients. Mean follow-up after surgery was 56 months. Six patients had recurrent tumors. Surgery is the gold standard for treatment of JNA. Modern imaging techniques allow accurate diagnosis and staging of JNA. Our experience and a review of the literature shows that the surgical approach should be selected according to tumor stage.

Extensive juvenile nasopharyngeal angiofibromas are efficiently managed with a multimodal protocol in which preoperative embolization is followed by optimal surgical removal using various transcranial or transfacial approaches. Adjunctive gamma knife radiosurgery is a valuable option for intracavernous residual tumor. Our protocol offers long-term cure with acceptable morbidity.
