Histology of the nasal septal swell body (septal turbinate).

OBJECTIVE: To analyze the vascular and glandular elements of the nasal septal swell body (NSB) and quantitatively compare these to the inferior turbinate (IT) and non-swell body portion of septum. STUDY DESIGN: Fourteen healthy adults undergoing septoplasty and IT reduction were submitted to unilateral biopsies of the NSB, the adjacent inferior turbinate, and inferior septum. Photomicrography with morphometric analysis was used to determine the relative area proportions of each tissue type. RESULTS: NSB was rich in seromucinous glands (49.9% +/- 7.0%) compared to IT (19.9% +/- 5.5%), P < 0.01. Conversely, IT mucosa demonstrated increased area proportion of venous sinusoids (28.3 +/- 13.9) compared to NSB (10.0 +/- 6.0), P < 0.01. Inferior septal mucosa had glandular and vascular elements similar in proportion to that of NSB. CONCLUSIONS AND SIGNIFICANCE: NSB is a highly glandular structure of the anterior-superior septum, with moderate proportion of venous sinusoids. Located at the distal valve segment, the NSB appears structured for secretory function and vasoactive airflow regulation.

Partial inferior turbinectomy using the microdébrider.

BACKGROUND: A microdébrider was selected to accomplish partial inferior turbinectomy, allowing for controlled and rapid removal of hypertrophic soft tissue while preserving the general turbinate form. OBJECTIVE: To assess the clinical outcome, healing, and any adverse consequences from the microdébrider partial turbinectomy procedure. SETTING: A public hospital in north-central Israel. DESIGN: A nonrandomized prospective study of 35 adults who were referred for nasal airway surgery, including turbinectomy. METHODS: All patients underwent bilateral inferior turbinate reduction with the microdébrider, with removal of mucosa from the medial and inferior portions of the inferior turbinates. Detailed follow-up was accomplished at 4 or more months postoperatively, including a visual analogue scale questionnaire and videoendoscopy. For seven patients, pre- and postoperative mucosal biopsies were available to evaluate healing and epithelial regeneration. RESULTS: Nasal endoscopy showed well-healed turbinate membranes and preservation of the turbinate form, with widening of the inferomedial nasal airway space. Subjective nasal patency improved after surgery, p < .01, and the subjective sense of smell was improved, p < .01, without associated crusting, pain, irritation, sneezing, or dryness. Postoperative biopsies showed subepithelial fibrosis and regenerated epithelium, generally of respiratory differentiation. CONCLUSION: Inferior turbinate reduction can be accomplished efficiently with the microdébrider device, without undue side effects. SIGNIFICANCE: Further experience and long-term follow-up with this technique are warranted.
