Brief Summary:
Study Title: Assessing the Clinical Significance of Using Fascia Lata versus Temporalis Muscle Fascia for Skull Base Reconstruction in Sellar Region
Objective: The primary objective of this study is to investigate and compare the effectiveness and safety of using fascia lata and temporal muscle fascia in the reconstruction of the skull base in the sellar region. Specifically, the study aims to determine and compare the level of donor site pain between the two groups using Visual Analogue Scales (VAS). The study also aims to identify the optimal method and materials for skull base reconstruction that result in the lowest frequency of complications, thereby reducing perioperative morbidity and enabling earlier rehabilitation of patients.
Subjects and Methods:
Study Design: Prospective randomized controlled trial. Population: The study will enroll 68 patients who have undergone endoscopic endonasal surgery for sellar region pathology. Patients will be divided into two groups: one group will receive skull base reconstruction using fascia lata, and the other group will receive reconstruction using temporal fascia.
Interventions: In the fascia lata group, grafts will be harvested from the thigh, while in the temporal fascia group, grafts will be harvested from the temporal muscle area.
Measurements:
Primary Outcome: Donor site pain measured using Visual Analogue Scales (VAS) at various postoperative intervals (preoperative, and on the 1st, 2nd, and 3rd postoperative days, as well as 1 month and 3 months post-surgery).
Secondary Outcomes: Incidence of postoperative complications such as meningitis, cerebrospinal fluid (CSF) leak, donor site infection, and other surgical complications.
Expected Contribution: This research is expected to provide valuable insights into the comparative effectiveness and safety of using fascia lata versus temporal muscle fascia for skull base reconstruction. The findings could influence clinical decisions regarding the choice of graft material, potentially leading to reduced perioperative morbidity, faster patient rehabilitation, and improved overall outcomes for patients undergoing skull base surgeries.

Detailed Description:
Study Title: Assessing the Clinical Significance of Using Fascia Lata versus Temporalis Muscle Fascia for Skull Base Reconstruction in Sellar Region
Study Objective: The primary objective of this prospective randomized controlled study is to evaluate and compare the effectiveness and safety of using fascia lata and temporal muscle fascia for skull base reconstruction in the sellar region following endoscopic endonasal surgery. The study aims to determine the level of donor site pain using Visual Analogue Scales (VAS) and to identify the optimal reconstruction method with the lowest complication rates.
Background: Tumors in the sellar region, such as pituitary adenomas, craniopharyngiomas, meningiomas, and chordomas, present significant surgical challenges due to their location. Advances in endoscopic techniques have improved surgical outcomes for these tumors, but complications, particularly cerebrospinal fluid (CSF) leaks, remain common. Reconstruction of skull base defects is critical to prevent CSF leaks and associated infections. Autologous grafts, including fascia lata and temporal muscle fascia, are commonly used for this purpose. This study seeks to compare these two graft materials in terms of effectiveness, safety, and patient quality of life post-surgery.
Study Design:
Type: Prospective randomized controlled trial. Enrollment: 68 adult patients.
Randomization: Participants will be randomly assigned to one of two groups:
Group 1: Skull base reconstruction using fascia lata. Group 2: Skull base reconstruction using temporal muscle fascia. Blinding: Single-blind (patients will not know which type of fascia is used for their reconstruction).
Duration: The study will commence in August 2023 and is expected to last for 2-3 years.
Inclusion Criteria:
Adult patients (18 years and older) undergoing endoscopic endonasal surgery for sellar region tumors.
Patients requiring reconstruction of the sellar floor to prevent postoperative CSF leaks.
Exclusion Criteria:
Pathology at the donor site (trauma, previous surgery). Absence of intraoperative CSF leak. Use of alternative reconstruction materials. Prior radiation therapy to the operative or donor site.
Interventions:
Group 1 (Fascia Lata): Grafts harvested from the thigh. Group 2 (Temporal Fascia): Grafts harvested from the temporal muscle area. All surgeries will be performed by a standardized surgical team comprising a neurosurgeon and an otolaryngologist. The techniques for incision, hemostasis, and reconstruction will be consistent across all procedures.
Outcome Measures:
Primary Outcome:
Donor site pain assessed using Visual Analogue Scales (VAS) at the following time points: preoperative, postoperative days 1, 2, and 3, and at 1 and 3 months post-surgery.
Secondary Outcomes:
Incidence of postoperative complications such as meningitis, CSF leak, donor site infection, wound dehiscence, seroma, facial nerve palsy, hypoesthesia of the donor site skin, and diabetes insipidus (temporary or permanent).
Quality of life measured using the EQ-5D-5L questionnaire before surgery and at 1 and 3 months postoperatively.
Duration of surgical procedures. Length of hospital stay.
Statistical Analysis:
Power Analysis: A sample size of 34 participants per group is required to achieve 80% power to detect a 30% difference in the incidence of mild versus moderate/severe pain (VAS \> 3.5), with a significance level of α = 0.05. Power analysis was conducted using MedCalc® Statistical Software version 22.003.
Data Analysis: Normality of data distribution will be tested using histograms and the Kolmogorov-Smirnov test. Continuous variables will be presented as mean (95% confidence interval) or median (interquartile range), depending on distribution. Categorical variables will be presented as absolute frequencies and percentages. Differences in continuous variables between groups will be analyzed using one-way ANOVA with post-hoc tests for parametric data or Kruskal-Wallis test with Dunn's post-hoc test for non-parametric data. Differences in categorical variables will be analyzed using Fisher-Freeman-Halton test for independent samples or McNemar's test for paired samples. A significance level of p \< 0.05 will be considered statistically significant. Data analysis will be performed using IBM SPSS Statistics version 29.0.1.
Ethical Considerations:
The study has been approved by the Ethics Committee of KBC Zagreb. Informed consent will be obtained from all participants prior to their inclusion in the study.
Participant privacy will be protected by anonymizing personal data and using unique coded identifiers. Access to anonymized data will be strictly controlled, and any de-anonymization will occur only under the supervision of the Ethics Committee.
Funding: The study is funded through clinical research funds dedicated to scientific investigations at KBC Zagreb.
Expected Contributions: The study aims to provide empirical evidence on the comparative effectiveness and safety of fascia lata versus temporal muscle fascia for skull base reconstruction. Results will guide clinical decision-making, potentially reducing perioperative morbidity, enhancing patient recovery, and improving quality of life post-surgery.
