Claim 10

A surgical kit comprising a sealable envelope, nasal tampon material and the turbinate sheath device according to claim 7.

Claim 11

In an endoscopic nasal surgery method wherein the human middle turbinate, contiguous paranasal sinuses or nasal septum is subjected to surgical procedure, an improved post-operative healing technique which comprises: applying to the post-operative middle turbinate through opposite nasal passages a pair of resilient septal plate members adapted for insertion on opposite sides of the nasal septum, each of said septal plate members having a front plate portion and rear plate portion and an integrally formed turbinate sheathing portion extending along an outer surface of said plate member in a substantially horizontal position, said turbinate sheathing portion being U-shaped with an upper open slot portion adapted to receive and hold the middle turbinate during post-operative healing; said turbinate sheathing portion extending outwardly from the plate member at a mid-portion thereof with a reverse curved sheathing wall laterally spaced from the rear plate portion to form said slot portion, wherein the sheathing wall has an elongated horizontal portion adapted to grip the middle turbinate and an outward flare portion adapted to guide the turbinate sheathing portion over the middle turbinate during insertion; and securing the pair of septal plate members in position overlying the middle turbinate, thereby separating the middle turbinate from the nasal septum to prevent medial adhesion and separating the middle turbinate from the nasal wall to prevent lateral adhesion during healing.

Claim 12

In an endoscopic nasal surgery method wherein the human middle turbinate, contiguous paranasal sinuses or nasal septum is subjected to surgical procedure, an improved post-operative healing technique which comprises: applying to the post-operative middle turbinate through opposite nasal passages a pair of resilient septal plate members adapted for insertion on opposite sides of the nasal septum, each of said septal plate members having a front plate portion and rear plate portion and an integrally formed turbinate sheathing portion extending along an outer surface of said plate member in a substantially horizontal position, said turbinate sheathing portion being U-shaped with an upper open slot portion adapted to receive and hold the middle turbinate during post-operative healing; said turbinate sheathing portion extending outwardly from the plate member at a mid-portion thereof with a reverse curved sheathing wall laterally spaced from the rear plate portion to form said slot portion, wherein the sheathing wall has an elongated horizontal portion adapted to grip the middle turbinate and an outward flare portion adapted to guide the turbinate sheathing portion over the middle turbinate during insertion; and securing the pair of septal plate members in position overlying the middle turbinate, thereby separating the middle turbinate from the nasal septum to prevent medial adhesion and separating the middle turbinate from the nasal wall to prevent lateral adhesion during healing.

Claim 13

The endoscopic nasal surgery method of claim 9 wherein simultaneous septoplasty is performed on the nasal septum and the pair of septal plate members is secured on opposite sides of the nasal septum for support thereof to promote straight healing.

Claim 14

In human ethmoidectomy, frontal sinusotomy, maxillary antrostomy, or sphenoidectomy surgery wherein the human middle turbinate is subjected to surgical procedure, an improved post-operative healing technique which comprises: inserting over at least a portion of the post-operative middle turbinate a turbinate sheath device comprising a septal plate member having a front plate portion and rear plate portion and an integrally formed turbinate sheathing portion extending along an outer surface of said rear plate portion in a substantially horizontal position, said turbinate sheathing portion extending outwardly from the plate member with a curved sheathing wall laterally spaced from the rear plate portion to form a slot portion, wherein the sheathing wall has an elongated horizontal portion, guiding the turbinate sheathing portion over the middle turbinate during insertion and gripping the middle turbinate, and securing the septal plate member in position overlying the middle turbinate, whereby the middle turbinate is separated from the septum to prevent medial adhesion and separated from the nasal wall to prevent lateral adhesion.
