February 15, 2025 updated by: Dr. Birat Thapa Magar, University of Health Sciences Lahore

Comparison Between Surgical Outcomes of Craniotomy and Craniectomy Among Patients with Posterior Fossa Lesion

The purpose of this randomized controlled trial is to compare the surgical outcomes of craniotomy and craniectomy among patients with posterior fossa lesions. The study aims to determine differences in post-operative complications, hospital stay duration, and patient recovery between the two surgical techniques.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Patients diagnosed with posterior fossa lesions will be randomly assigned into two groups. Group A will undergo craniotomy, where the bone flap is replaced after dural closure, while Group B will undergo craniectomy, where the bone is permanently removed. Outcomes will be assessed based on post-operative complications such as CSF leakage, pseudomeningocele formation, post-operative headache, and length of hospital stay. The study aims to provide evidence to determine the superior surgical approach in terms of patient outcomes and healthcare cost reduction.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Group A: Craniotomy
This procedure involves creating a single free bone flap using high-speed drills. The bone is repositioned and secured using mini plates or sutures after the surgical intervention is completed. Post-operative monitoring will include assessment for CSF leakage, wound healing, and neurological recovery.
Procedure: Craniotomy
Intervention: Bone flap replaced after dural closure Additional Information: This procedure involves creating a single free bone flap using high-speed drills. The bone is repositioned and secured using mini plates or sutures after the surgical intervention is completed. Post-operative monitoring will include assessment for CSF leakage, wound healing, and neurological recovery.
Active Comparator: Group B: Craniectomy
In this approach, the bone is removed in pieces using rongeurs, leaving an open dural surface without replacement of the bone. The dura is closed with sutures, and dural augmentation may be performed as needed. Post-operative assessment will focus on complications such as pseudomeningocele, CSF leakage, and extended hospital stays.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Incidence of CSF leakage
Time Frame: Up to 6 months post-surgery

Definition: CSF leakage is defined as the presence of clear fluid discharge from the surgical site, confirmed via clinical examination and biochemical analysis of β-2 transferrin.

Measurement: Evaluated by clinical assessment at routine follow-ups and imaging studies when indicated.
Up to 6 months post-surgery
Occurrence of pseudomeningocele
Time Frame: Up to 6 months post-surgery

Definition: Pseudomeningocele is defined as an abnormal collection of cerebrospinal fluid in the surgical site, detected through physical examination and confirmed by imaging techniques such as MRI or CT scan.

Measurement: Follow-up visits at 1, 3, and 6 months post-surgery.
Up to 6 months post-surgery
Severity of post-operative headache
Time Frame: Immediately post-surgery, at 3 months, and at 6 months post-surgery

Definition: Post-operative headache will be assessed using the Catalano grading system, categorizing severity from 0 (no headache) to 4 (severe, refractory to medication).

Measurement: Self-reported patient evaluations at each follow-up visit.
Immediately post-surgery, at 3 months, and at 6 months post-surgery
Length of hospital stay
Time Frame: From immediate post-surgery until hospital discharge, assessed up to 4 weeks

Definition: The total number of days a patient remains hospitalized post-surgery, including any extended stay due to complications.

Measurement: Recorded from hospital admission to discharge.
From immediate post-surgery until hospital discharge, assessed up to 4 weeks
