A Combination of Scoring and Modified Mattress Suture Technique for the Management of Caudal or Dorsal Septal Deviations: In Vitro and In Vivo Results

Background/Objectives: Septal deviation is a common cause of nasal obstruction, and achieving long-lasting septal straightening while preserving cartilage remains a surgical challenge. In this study, we describe and evaluate a simple suture technique designed to effectively straighten the nasal septum in both experimental and clinical settings. Methods: The technique combines cartilage scoring with the placement of a mattress suture to correct septal deformities. It was first tested in vitro using fifteen rabbit ear cartilage specimens and subsequently applied in vivo in a clinical series of forty-five patients presenting with septal deviation. The approach was assessed for ease of application, suitability in difficult anatomical regions (including severe caudal or dorsal deviations), cartilage preservation, and durability of correction. Clinical outcomes were followed for up to twelve months. Results: The combined scoring and mattress suture technique successfully straightened cartilage in both experimental and clinical applications. The method proved technically straightforward and applicable even in challenging septal areas. It allowed for conservative management with increased cartilage preservation. In the patient cohort, initial favorable outcomes were maintained throughout follow-up period. Conclusions: This simple suture technique represents an effective and conservative method for septal straightening. It is easy to perform, preserves cartilage, and seems to provide stable short- to mid-term results. The method may be particularly useful in cases of severe caudal or dorsal septal deviation.
