Lateral Crural Strut Graft vs Bone-Anchored Suspension for Treatment of Lateral Nasal Wall Insufficiency

Stanford University

Overview

Lateral nasal wall insufficiency is a source of nasal obstruction which plagues many people as the sidewall of the nose collapses due to negative pressure and structural weaknesses of the nose. Bone anchored suture suspension is used by many surgeons to treat it, and involves anchoring the nasal sidewall to the bony rim below the eye. Lateral crura strut graft is another well described and universally used technique involves strengthening lateral crus of lower lateral cartilage of the nose with piece of cartilage. This study aims to compare the two well known and universally used treatments to each other. Based on expert opinions these procedures are both safe and efficient but given lack of randomized clinical trials comparing these 2 techniques, it is difficult to extrapolate which procedure is superior.

Patients with lateral nasal wall collapse who are eligible for surgical repair will be presented with the opportunity to participate. Once consented, standard pre-operative evaluation will be performed including evaluation of degree of lateral nasal wall collapse. They will also be screened with validated quality of life screening tools for nasal congestion, which include the NOSE scale and a visual analog scale. They will then be randomized to treatment either with Lateral crura strut graft or bone anchored suture suspension, in combination with likely other areas of functional rhinoplasty such as septoplasty and turbinate reduction. All of our patients will be seen 1 week, 2-3 month and 1 year after surgery

Outcomes

Primary Outcomes

NOSE (Nasal Obstruction Symptom Evaluation)score change from baseline to 12 months post op

Nasal Obstruction Symptom Evaluation (NOSE) scale is a validated disease-specific questionnaire for the assessment of Nasal Obstruction (NO)

Time frame: 1 year

Secondary Outcomes

Visual Analogue Scale for nasal obstruction

The scale is a 10-cm horizontal line anchored by word descriptors. It is scored by measuring the distance in millimeters from the left of where the patient's mark was placed. A higher number indicates more severe symptoms.

Time frame: 1 year

Visual analogue scale for satisfaction with appearance of the nose

Time frame: 1 year

physician derived lateral wall insufficiency grading system

This is a validated grading system which is measured by physician based on degrees of nasal valve insufficiency

Time frame: 1 year
