Transorbital approach to infratemporal fossa: novel technique
Abstract
OBJECTIVE: To present a conservative surgical approach, via the transorbital route, for selected cases of infratemporal fossa involvement or inferolateral orbital tumours extending to the infratemporal fossa.
DESIGN: Case series report.
SETTING: Department of ENT, CSM Medical University (King George Medical College), Lucknow, India.
PARTICIPANTS: One patient.
MAIN OUTCOME MEASURES: Operative feasibility, intra-operative access, post-operative morbidity and cosmesis.
RESULTS: This novel and relatively conservative technique provides excellent exposure in selected cases of infratemporal fossa involvement and has minimal post-operative morbidity. Cosmesis is excellent, as osteotomy is not required and scarring is minimal. There is no risk of trismus, Vth or VIIth cranial nerve injury, or cerebrospinal fluid leakage, and haemostasis is easily achieved.
CONCLUSION: Classical, open approaches to the infratemporal fossa involve considerable morbidity, while conservative approaches have their limitations. Diagnostic uncertainty over a small infratemporal fossa mass (perhaps an extension from an inferolateral orbital tumour) is an uncommon clinical challenge. The transorbital approach described is suited to benign and early malignant tumours, and has excellent results when combined with orbital exenteration (if needed). This paper discusses this approach's technical details and feasibility in different clinical situations, and compares it with other infratemporal fossa approaches.
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
