Outcomes of Different Endoscopic Turbinoplasty Techniques for Symptomatic Middle Turbinate Concha Bullosa

Background: The middle turbinate is an important anatomical structure and plays as a key landmark in endoscopic sinus surgery. this study aimed at assessing and comparing intra- and postoperative outcomes of different endoscopic turbinoplasty techniques for symptomatic middle turbinate Concha Bullosa (CB). Methods: This interventional comparative study included 32 patients with symptomatic CB presented to outpatient clinic of Benha University Hospitals. Patients were randomly divided into three groups: Group A (n=10): submitted for chonchal crushing tecnique, Group B (n=11) submitted for lateral laminectomy chonchoplasty technique. Group C (n=11) submitted for modified Har-El and Slavit techniques. Results: Most postoperative complications showed no statistically significant differences between groups, except for synechia at 6 months. At this point, synechia was observed only in Group B (36.4%), while none were reported in Groups A or C. Crusting was most common at 1-month post-op, particularly in Group B (90.9%), but decreased overtime in all groups, resolving completely by 6 months. Similarly, synechia was highest at 1 month across all groups (71.9% overall), then declined by 3 months and was significantly less prevalent by 6 months. Conclusion: All three surgical techniques are effective for symptomatic concha bullosa , but with distinct profiles. Group A (crushing) was quickest and safest but gave slightly less symptom reduction by 6 months. Group B (lateral resection) was highly effective but carried higher adhesion risk. Group C (modified Har-El/Slavit) balanced efficacy and safety, yielding excellent relief with minimal synechiae at the cost of greater operative time and technically more difficult.
