Abstract:
Objective: JNA is a histopathologically benign, highly vascular tumor and
seen exclusively in adolescent males involving the nasopharynx, anterior
skull base, pterygoid-infratemporal fossa and other areas. It comprises 0.05%
of total head and neck tumors. This paper deals with the authors experience
of 32 such cases treated between 1990–2006 and 2007-2011 in two different
institutes. Ten different approaches have been designed and adopted with
and without the use of laser.
Design: Depends exclusively on tumour extension. Advantages, disadvantages
of these approaches and its role in complete removal and prevention
of recurrences of these tumours will be discussed.
Materials & Methods: No. of cases (1990- 2006) - 31case and from (2007-
2011) - 1 case, Mean age: 16.8 yr (Youngest 12 & oldest 35 yrs). Preoperative
Embolization - 18 cases. Ten different approaches have been adopted. Transpalatal
lateral rhinotomy:2, Midfacial degloving:5, Biller’s lateral Rhinotomy:6,
Craniofacial resection:3, Frontotemporal craniotomy:3, Endoscopic transnasal
transpalatal:6, endoscopic approach with or without ECA clamping:5, Le
Fort Type 1 osteotomy:2.
Result: All the approaches has given adequate exposure for complete excision
excepting the one in craniofacial group where tumour could not be excised
completely because of involvement of cavernous sinus. Paper will also
highlights the Endoscopic and Le-Fort type 1 approach in tumours, involving
the anterior skull base where the external incision can be avoided and same
is greatly preferred by the patients.
Conclusion: Surgical excision of both nasopharyngeal, anterior skull base
and extra nasopharyngeal JNA tumors almost always requires a combination
of approaches. However, endoscopic assisted surgery with or without the use
of laser for this type of skull base tumour may be going to be the preferred
approach for many authors because of patient’s compliance.
