Perforation location (n)
Anterior	7
Middle	4
Posterior	1
Documented subjective olfactory dysfunction	8/314 (2.5)	1.3–4.9
Sphenoid polypoid mucosal change	5/314 (1.6)	0.7–3.7
Synechia	5/314 (1.6)	0.7–3.7
Sinonasal infection	3/314 (1.0)	0.3–2.8
Saddle nose	3/314 (1.0)	0.3–2.8

All denominators are the 314 procedures with an eligible ENT assessment 60–120 days after surgery. Multiple morbidities could coexist.
An unmentioned individual finding was coded as absent when an ENT assessment was documented, as in the reviewed dataset; this is not proof of normal olfactory function.
Intentional posterior septectomy was not classified as septal perforation. Confidence intervals are Wilson score intervals.
CI, confidence interval; ENT, ear, nose, and throat.
