Abstract

Objective

Endoscopic endonasal transsphenoidal surgery (EETS) is still rarely used in pediatric subjects compared with adults. Reports on EETS in children appeared only recently in the literature, usually regarding small series. The aim of the study is to assess the actual role and the limits of EETS in children with sellar tumors by reporting a two-centers experience.

Methods

Twenty-seven children (mean age: 12.2 years) were operated on during the last decade. Seventeen patients harbored a sellar mass, 7 a suprasellar tumor, and 3 a clival mass. Laboratory investigations revealed hypopituitarism in 6 children and hormone hypersecretion in 9. All the operations were carried out by a team including both ENT surgeon and neurosurgeon using a dedicated 18-cm long rigid endoscope (2.7 mm and 4 mm diameter) through the direct paraseptal or the transethmoidal or the transpterygoid route.

Results

Overall, 29 operations were performed. Gross total tumor resection was obtained in 22 children (81.5%) while a subtotal and a partial removal in 2 (7.5%) and 3 cases (11%), respectively. Pituitary adenoma was the most common histotype (12 cases), followed by craniopharyngioma (5) and Rathke's cleft cyst (4). No surgical mortality or neurological morbidity or late nasal complications were observed. Postoperative CSF fistula occurred in 3 patients. All children are alive at current follow-up (average: 8.6 years). Preoperative hypopituitarism disappeared or improved in 4 cases and was stable in the remaining 2 (no new hormone deficits appeared).

Conclusion

EETS is a safe and effective surgical option also in children. As for adults, it allows to manage most of the tumor lesions of the sellar region with stable long-term results.

Introduction

In the last two decades, neuroendoscopy underwent an impressive development in terms of techniques and sophisticated surgical tools that currently permits to treat a wide range of diseases. Endoscopic endonasal transsphenoidal surgery (EETS) has become a relatively common surgical procedure to treat the anterior skull base tumors, especially in adult patients. EETS is less utilized in the pediatric population mainly because of the higher prevalence of such tumors in adults (namely pituitary adenomas and meningiomas) and the less favorable anatomical conditions in children (minute nostrils, narrow nasal cavities, reduced/absent pneumatization of the sphenoid sinus). However, some studies concerning EETS in small series of children have recently appeared, showing an effectiveness of the procedure comparable to that of the older counterpart [1], [2], [3], [4].

We describe the results obtained with EETS in the largest series of children with tumors of the sellar and clival region reported so far. The goal of this report is to evaluate whether EETS is a suitable surgical option in pediatric subjects.

Series

The series is composed by 27 pediatric patients (11 boys and 16 girls) operated on at the Neurosurgical Unit of the San Matteo Hospital, Pavia, Italy, and at the Pediatric Neurosurgery of the A. Gemelli Hospital, Rome, Italy, during the last decade. The mean age at surgery was 12.2 years, ranging from 4 to 18 years. Seventeen patients harbored a purely sellar mass, 7 a sellar/supra- and para-sellar tumor, and 3 a clival mass. The conchal variant of the sphenoid sinus was found in one case.

Results

Overall, 29 surgical procedures were performed (2 children required a second EETS; see below). The approach was carried out through a direct paraseptal route in 24 cases (bilateral in 18 and monolateral in 6), through a transethmoidal approach in 4 and through a transpterygoid approach in the remaining one. Two children underwent EETS as secondary procedure following a previous transcranial approach.

Based on MRI, a gross total resection of the tumor was obtained in 81.5% of the cases (22

Discussion

In spite of the increasing application of EETS in the pediatric population, only a few studies concerning this subject are currently available in the literature. Most of them consider small pediatric series, alone or as part of mixed cohorts, or series where the young patients are treated by combined approaches (e.g. transnasal and/or transcranial endoscopically assisted surgery) [1], [3], [4], [8], [9]. Among the series of 22 children with craniopharyngioma operated on by transsphenoidal route

      Nonetheless, although the EETA associated with a lesser risk of complications, the incidence of endocrine dysfunction is high in both (transcranial and endonasal) approaches [9]. Therefore, patients subjected to craniopharyngioma resection are later followed by an endocrinologist [10]. To increase the chances for optimal results using the EETA for craniopharyngioma resection, it is important that the anatomy (spatial relationship of the posterior wall of the sphenoid sinus and the anterior/posterior walls of the sella turcica) and pneumatization of the sphenoid sinus are studied preoperatively.

      Similar to those in adults, the main limits of this approach are asymmetric extension of the tumor, the pure intraventricular location, and encasement of the major vessels.2-18 Children present with some particular age-related limitations.18 Specifically, the anatomic features of the nose and paranasal sinuses are an absolute contraindication to treating children younger than 3 years.
