Introduction: In the surgical management of juvenile nasopharyngeal angiofibromas the possibility of recurrences and residual tumours is always there. This study was undertaken to predict the prognostic factors determining recurrence of juvenile nasopharyngeal angiofibroma and to find out the usual sites of these tumours.Material and methods: The medical records of 95 patients with histologically proven juvenile nasopharyngeal angiofibroma were reviewed retrospectively. The commonest surgical approach used was a combined transpalatal and transmaxillary approach with a lazy S incision. A conservative lateral infratemporal approach was used in three cases.Results: Complete removal of the juvenile nasopharyngeal angiofibroma was achieved in 78 (82 per cent) of the cases in a single operation. A residual tumour was found in 17 (18 per cent) cases and recurrences occurred in 13 (13.7 per cent) cases.Conclusions: Extensions into the pterygoid fossa and basisphenoid, erosion of the clivus, intracranial extensions medial to the cavernous sinus, invasion of the sphenoid diploe through a widened pterygoid canal, feeders from the internal carotid artery, a young age and a residual tumour were risk factors found associated with recurrence of juvenile nasopharyngeal angiofibroma.

Cervical Ganglia

The cranial cervical ganglia (CCG) in the heads of six adult (three male and three female) Angora goats were dissected in detail. The ganglion was located on the ventral aspect of the tympanic bulla, cranio-ventral to the atlas, medio-ventral to the jugular process and lateral to the longus capitis muscle. The branches of the ganglion were the internal and external carotid nerves, the jugular and laryngopharyngeal nerves and the connecting branches to the vagus and glossopharyngeal nerve. The internal carotid nerve arose as three branches (cranial, caudal and medial) from the cranial region of the ganglion. The cranial branch, the profound petrosal nerve, entered the pterygoid canal. The caudal branch terminated at the trigeminal ganglion. The medial branch terminated at the cavernous sinus. The other cranial branch ramifying from the cranial region of the ganglion was the jugular nerve. The internal carotid and laryngopharyngeal nerves arose from the caudal region of the ganglion. In conclusion, compared with published data on other species, we found differences in the number and courses of the branches ramifying from the CCG of Angora goats and in the branches connected to the vagus, glossopharyngeal and hypoglossal nerves.

The Mean

The whole course of the chorda tympani nerve, nerve of pterygoid canal, and facial nerves and their relationships with surrounding structures are complex. After reviewing the literature, it was found that details of the whole course of these deep nerves are rarely reported and specimens displaying these nerves are rarely seen in the dissecting room, anatomical museum, or atlases. Dissections were performed on 16 decalcified human head specimens, exposing the chorda tympani and the nerve connection between the geniculate and pterygopalatine ganglia. Measurements of nerve lengths, branching distances, and ganglia size were taken. The chorda tympani is a very fine nerve (0.44 mm in diameter within the tympanic cavity) and approximately 54 mm in length. The mean length of the facial nerve from opening of internal acoustic meatus to stylomastoid foramen was 52.5 mm. The mean length of the greater petrosal nerve was 26.1 mm and nerve of the pterygoid canal was 15.1 mm.

AbstractSeventy-two patients with juvenile angiofibroma have been investigated by computerized tomography (CT) and/or magnetic resonance imaging (MRI) over a period of 20 years. The evidence from these studies indicates that angiofibroma takes origin in the pterygo-palatine fossa at the aperture of the pterygoid (vidian) canal. An important extension of the tumour is posteriorly along the pterygoid canal with invasion of the cancellous bone of the pterygoid base, and greater wing of the sphenoid (60 per cent of patients). Distinctive features of angiofibroma are the high recurrence rate, and the rapidity with which many tumours recur. It is postulated that the principle determinant of recurrence is a high tumour growth rate at the time of surgery coupled with incomplete surgical excision. The inability to remove the tumour in toto is principally due to deep invasion of the sphenoid, as described above. In this series 93 per cent of recurrences occurred withthis type of tumour extension. A contributory cause in these patients is the use of pre-operative embolization. The treatment implications of these findings are examined.
