Comparison of Outcomes of Conventional Septoplasty vs Conservative Endoscopic Septoplasty
Comparison of Outcomes of Conventional Septoplasty vs Conservative Endoscopic Septoplasty
OBJECTIVE To compare the outcome of conventional septoplasty and conservative endoscopic septoplasty for symptomatic deviated nasal septum.
DATA COLLECTION PROCEDURE This randomized control study will be conducted in the ENT department at Shaikh Zayed Hospital, Lahore, over six months. Ethical approval will be obtained and informed consent forms will be completed by all participants. A sample of 210 cases will be selected using a non-probability consecutive sampling technique, with patients randomized into two groups based on the lottery method: 105 will undergo conventional septoplasty (Group A), and 105 will undergo conservative endoscopic septoplasty (Group B). Detailed patient history and clinical examination will be recorded, and each case will be evaluated subjectively and objectively preoperatively. Nasal septal deviation will be classified based on the side (right, left, or S-shaped) and anatomical involvement (anterior, posterior, or both), with posterior rhinoscopy and diagnostic nasal endoscopy will be performed as needed to rule out other pathologies. For patients in the conventional septoplasty group, the traditional surgical technique for septoplasty will be applied in which bilateral flap elevation will be done. In the conservative endoscopic septoplasty group, an incision will be made 2 mm posterior to the caudal end of the septum (hemitransfixation) on the concave side to access the bony-cartilaginous junction abnormality. The initial mucoperichondrial flap will be elevated. Proper plane elevation will be performed to minimize bleeding, and exposure will be limited to the targeted area.
OPERATIONAL DEFINITIONS Conventional Septoplasty: A surgical procedure performed to correct a deviated nasal septum through bilateral mucoperichondrial flap elevation, removal or correction of the deviated septal segment, and repositioning of the septal cartilage and bone to improve nasal airflow. Assessment of outcome will be done through subjective (symptom relief) and objective (endoscopic findings) measures postoperatively.
Conservative Endoscopic Septoplasty: A minimally invasive septal correction technique performed under general anesthesia using a nasal endoscope. The surgeon elevates a single mucoperichondrial flap near the site of maximum deviation, visualizes the area directly, and precisely removes or repositions the deviated portion of the septum while preserving as much normal tissue as possible. Outcomes will be evaluated by comparing symptom improvement and endoscopic findings postoperatively.
Nasal Obstruction: Evaluated subjectively using a patient self-reported improvement scale and objectively by endoscopic assessment of nasal patency at follow-up visits.
Nasal Discharge: Assessed based on the patient's report of reduction or absence of discharge and confirmed through anterior rhinoscopic examination.
Headache: Monitored through patient-reported symptom relief using a standardized pain rating scale during postoperative follow-ups.
Residual Septal Deviation : Residual septal deviation is defined as the persistent deviation of the nasal septum from the midline, as observed after surgical intervention (e.g., septoplasty), and confirmed through endoscopic examination.
Septal Perforation: Septal perforation is defined as a full-thickness defect in the nasal septum-extending through the mucoperichondrium and/or mucoperiosteum and underlying cartilage or bone-creating an abnormal communication between the two nasal cavities. A visible hole or defect in the nasal septum confirmed by anterior rhinoscopy or nasal endoscopy.
Synechiae: Synechiae are defined as abnormal adhesions between the nasal septum and the lateral nasal wall or turbinates, resulting from healing after trauma, surgery, infection, or inflammation, and confirmed by clinical examination via nasal endoscopy Operative Parameters: Operative time from start of surgery till end of surgery in mins and intraoperative blood loss in ml, recorded during surgery.
HYPOTHESIS There is a significant difference between the outcomes of conservative endoscopic septoplasty and conventional septoplasty.
