Radical resection of a craniopharyngioma via the extradural anterior temporal approach with zygomatic arch osteotomy.

ABSTRACT:

Background

Though the extradural anterior temporal approach (EDATA) with zygomatic osteotomy is useful, there are only few reports of this approach being used for craniopharyngioma resection. Herein, we report our surgical case series and the technical importance of EDATA for the radical removal of a craniopharyngioma.

Methods

We report 7 cases of craniopharyngiomas treated surgically between April 1999 and October 2015. The surgical approaches, clinical presentation, pre and postoperative radiographic examination results, surgical outcomes, and morbidity were analyzed.

Results

The mean follow-up period was 89.1 months. The surgical approach was EDATA with zygomatic osteotomy in 4, combined interhemispheric translamina terminalis approach (IHTLA) and trans-sylvian anterior temporal approach (ATA) in 2, and IHTLA in 1 patient. Complete tumor resection was achieved in all cases, without any recurrence during the follow-up period. Transient morbidities were oculomotor nerve palsy in 2, and meningitis and hydrocephalus in 1 patient. There was 1 case of permanent morbidity due to hydrocephalus that needed a ventriculoperitoneal shunt, and 1 case of blindness on the operative side. Visual acuity and visual field improved in 4 cases, showed no change in 2 cases, and deteriorated in 1 case. Though the pituitary stalk was preserved in 2 cases, all 7 cases needed total hormone replacement therapy.

Conclusion

EDATA with zygomatic osteotomy ensures sufficient mobility of the internal carotid artery, and provides a good lateral and look up operative view. Hence, it can be used effectively for radical resection of craniopharyngiomas through the opticocarotid space and retrocarotid space.

Project description:Introduction The transcranial approach (TCA) has historically been used to remove craniopharyngiomas. Although the extended endoscopic endonasal approach (EEA) to these tumors has been more commonly accepted in the recent two decades, there is debate over whether this approach leads to better outcomes. The goal of this systematic review and meta-analysis was to more comprehensively understand the benefits and limitations of these two approaches in craniopharyngioma resection based on comparative studies. Methods We conducted a systematic literature search in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses recommendations using MEDLINE, EMBASE, and the Cochrane Library. A total of 448 articles were screened. Data were extracted and analyzed using proportional meta-analysis. Eight comparative studies satisfied the inclusion criteria. The extent of resection, visual outcomes, and postoperative complications such as endocrine dysfunction and cerebrospinal fluid (CSF) leakage were compared. Results and discussion Eight studies, involving 376 patients, were included. Resection by EEA led to a greater rate of gross total resection (GTR) (odds ratio [OR], 2.42; p = 0.02; seven studies) with an incidence of 61.3% vs. 50.5% and a higher likelihood of visual improvement (OR, 3.22; p < 0.0001; six studies). However, TCA resulted in a higher likelihood of visual deterioration (OR, 3.68; p = 0.002; seven studies), and was related, though not significantly, to panhypopituitarism (OR, 1.39; p = 0.34; eight studies) and diabetes insipidus (OR, 1.14; p = 0.58; seven studies). Although TCA showed significantly lower likelihoods of CSF leakage (OR, 0.26; 95% confidence interval [CI], 0.10–0.71; p = 0.008; eight studies) compared to EEA, there was no significant difference in meningitis (OR, 0.92; 95% CI, 0.20–4.25; p = 0.91; six studies) between the two approaches. When both approaches can completely resect the tumor, EEA outperforms TCA in terms of GTR rate and visual outcomes, with favorable results in complications other than CSF leakage, such as panhypopituitarism and diabetes insipidus. Although knowledge of and competence in traditional microsurgery and endoscopic surgery are essential in surgical decision-making for craniopharyngioma treatment, when both approaches are feasible, EEA is associated with favorable surgical outcomes.
