Augmentation of upper central incisor area: with or without removing of nasopalatinal canal contents?

I have treatment planned the #8 edentulous site for a bone augmentation and implant placement after osseointegration. The bone defect in the #8 site is very large and connected to the incisive canal. The periodontal health of the surrounding teeth is stable. I would prefer leaving the canal’s contents, as that is less traumatic, but alternatively it is a consideration to remove the canal contents to prevent soft tissue growth into the bone defect instead of osseous tissue. I could deliver a graft of 50% autogenous bone mixed with beta-tricalcium phosphate and hydroxyapatite or xenograft, use a titanium mesh as a scaffold, thin collagen membrane and PRF. What is your opinion? Leave or remove the canal contents? May soft tissue of the canal interfere with augmentation material and lead to:
1) grow of soft/fibrous tissue instead of osseous tissue
2) post-op pain symptoms (transient or worse – permanent) due to close contact of granules and nasopalatinal nerves?
