Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine efficacy, safety, and ease of cartilaginous grafting using polydioxanone (PDS) plates in comparison to non-plated cartilaginous grafts as performed through an endonasal rhinoplasty approach in patients requiring a caudal septal extension (CSE) graft.

Polydioxanone (PDS) plates

15 subjects will be randomized to receive a caudal septal extension graft using a PDS plated cartilagenous graft

Group Type EXPERIMENTAL

Polydioxanone (PDS) plates

Intervention Type DEVICE

0.5 mm PDS Flexible Plate made of poly-p-dioxanone, an aliphatic polyester which is manufactured by polymerization of the monomer p-dioxanone. Polydioxanone is a resorbable material degraded by hydrolysis and has been successfully used for bone discontinuities and septal reconstruction.

Caudal septal extension graft performed through endonasal rhinoplasty

Intervention Type PROCEDURE

The caudal septal extension (CSE) graft is a common method used to alter tip projection, alar-columellar relationship, and nasolabial angle.5 However, it can be difficult to stabilize and straighten the CSE graft, especially when performed through an endonasal approach. Use of a polydioxanone plate would provide a scaffolding for the CSE graft and could allow for a technically easier and more predictable surgical procedure.

Non-plated cartilagenous graft

15 subjects will be randomized to receive a cartilagenous caudal septal extension fgraft

Group Type OTHER

Caudal septal extension graft performed through endonasal rhinoplasty

Intervention Type PROCEDURE

The caudal septal extension (CSE) graft is a common method used to alter tip projection, alar-columellar relationship, and nasolabial angle.5 However, it can be difficult to stabilize and straighten the CSE graft, especially when performed through an endonasal approach. Use of a polydioxanone plate would provide a scaffolding for the CSE graft and could allow for a technically easier and more predictable surgical procedure.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Males and females between 18 and 65 years of age.
* Subjects requesting primary or secondary rhinoplasty and requiring a CSE graft performed through an endonasal approach.
* Subjects willing to undergo PDS plating.
* Subjects with either ear conchal or septal cartilage available for grafting purposes.
* Willingness and ability to comply with protocol requirements, including returning for follow-up visits and abstaining from exclusionary procedures for the duration of the study.
* Willingness and ability to comply with the PI's standard preoperative and postoperative rhinoplasty instructions.
* Subjects of childbearing potential must have a negative urine pregnancy test result at Visit 1 and be willing able to use an acceptable method of birth control (e.g., barrier methods used with a spermicidal agent, hormonal methods, IUD, surgical sterilization, abstinence) during the study. Women will not be considered of childbearing potential if one of the following is documented on the medical history:
* postmenopausal for at least 12 months prior to study drug administration
* without a uterus and/or both ovaries
* has had a bilateral tubal ligation for at least 6 months prior to study drug administration.
* absence of an other physical condition according to the PI's discretion
* Willingness and ability to provide written photo consent and adherence to photography procedures (i.e., removal of jewelry and makeup).
* Willingness and ability to provide written informed consent prior to performance of any study related procedure.

Exclusion Criteria

* Subjects who are pregnant, nursing, planning to become pregnant, and/or not using a reliable form of birth control.
* Subjects with a significant systemic illness or illness localized to the areas of treatment.
* Subjects with previous history of nasal implants.
* Subjects with previous or current history of nasal infections.
* Subjects who have history of blood thinners (aspirin, ibuprofen, naprosyn, herbal supplements, Vitamin E) within the two weeks prior to surgery.
* Subjects who have smoked within the two weeks prior to surgery.
* Subjects who have had alcohol or illicit drugs one week prior to surgery.
* Subjects who have eaten or drank anything after midnight the night prior to surgery.
* Subjects with current history of chronic drug or alcohol abuse.
* History of autoimmune disease.
* Concurrent therapy that, in the investigator's opinion, would interfere with the evaluation of the safety or efficacy of the study medication.
* Subjects who anticipate the need for surgery, other than the study procedure, or overnight hospitalization during the study.
* Subjects who, in the Investigator's opinion, have a history of poor cooperation, non compliance with medical treatment or unreliability.
* Enrollment in any active study involving the use of investigational devices or drugs.
