This study aimed to systematically review the evidence on functional outcomes following dorsal preservation rhinoplasty, with a focus on nasal obstruction.

A systematic review was conducted according to Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. PubMed, Embase, Scopus and Cochrane databases were searched up to March 2025. Studies reporting nasal airway outcomes following dorsal preservation rhinoplasty using subjective or objective measures were included.

Six studies comprising 662 patients were included. Patient-reported outcomes (Nasal Obstruction Symptom Evaluation, Standardized Cosmesis and Health Nasal Outcomes Survey and Visual Analogue Scale) consistently demonstrated significant post-operative improvement. Objective measures (acoustic rhinometry, rhinomanometry and cone-beam computed tomography) showed maintained or improved airway dimensions. dorsal preservation rhinoplasty was functionally equivalent to traditional structural techniques, with low complication (<5 per cent) and revision rates (<2 per cent).

Dorsal preservation rhinoplasty maintains or improves nasal airway function while preserving structural integrity and reducing the need for grafting. It is a safe and effective alternative to traditional dorsal reduction techniques.
