Is there any difference in post-operative edema and ecchymosis between internal and external lateral nasal osteotomy techniques of rhinoplasty?
Adult patients without craniofacial syndromes or deformity who undergone rhinoplastic surgery.
Internal nasal osteotomy procedure in rhinoplastic surgery which is a cut at the level of the inner nasal mucosa is created. Osteotomy is begun at the anterior end of the inferior turbinate perpendicular to the face of the pyriform aperture and continued in a curved fashion toward the medial canthal area.
External nasal osteotomy procedure in rhinoplastic surgery which is a small cutaneous incision is created in the nasal osteotomy site. using a sharp straight osteotome, multiple pointwise osteotomies are made along the intended osteotomy line.
Primary outcomes include:
1. Edema after surgery measured by amount of pupillary coverage by upper and lower eyelids (4 grades)
2. Ecchymosis after surgery measured by amount of eyelid discoloration (3 grades)
Secondary outcomes include:
1. Bleeding in surgery and after that measured by milliliter
2. Late complication included (step and mucocyst) (present/absent)
3. Internal nasal valve changes measured in cubic centimeters (cm3)
4. Functional obstructions of nose assessed by patient examination
5. Tearing of nasal mucosa (present/absent)
