Background: Concha bullosa, an extensively pneumatized middle turbinate, may obstruct the paranasal sinuses. Messerklinger’s partial lateral turbinectomy is commonly used to debulk the concha bullosa, leaving a raw surface with the potential for adhesions.

Materials and methods: A modified technique of partial lateral turbinectomy is described. A posterior pedicled mucosal flap covers the inferior raw surface of the medial lamella of the middle turbinate. Three-month follow up of a consecutive series is compared with concurrent controls.

Results: Two (7 per cent) of 28 posterior pedicled flap and four (21 per cent) of 19 traditional partial lateral turbinectomies developed mild middle meatal adhesions (p = 0.011). Posterior pedicled flap reduced the need for post-operative cleaning of the middle meatus.

Conclusion: The posterior pedicled mucosal flap is a simple modification to partial lateral turbinectomy that covers the raw surface facing the lateral nasal wall, significantly reducing adhesions and speeding recovery.
