The goal of this observational study is to compare the effect of Piezo and endonasal osteotomy techniques on the healing process of patients undergoing septorhinoplasty surgery. The main question[s] it aims to answer are:

• In which osteotomy technique the edema is lesser?
• Which osteotomy technique is better for thick vs thin skinned patients ? In which osteotomy technique the healing process is faster?

Participants will be asked to have an ultrasonic measurement of the nasal dorsum preoperatively and at the first, third and tenth months postoperatively.

Researchers will compare the thick and thin skinned patients to detect which osteotomy technique is superior in the healing process ( lesser edema and faster healing due to skin thickness measurements)

18-65 years old males or females with nasal septum and/or nasal pyramid deviation and external nasal deformities who are willing to undergo open rhinoplasty procedure will be included in the study. Patients who have a history of previous rhinoplasty/septorhinoplasty procedure, abnormal coagulation parameters (prothrombin time, partial thromboplastin time, bleeding/coagulation time), use of anticoagulant drugs, chronic / inflammatory skin disease and/or chronic skin allergies, systemic diseases (hypertension, diabetes mellitus, bronchial asthma), nasal beautification procedures such as dermal fillings, using oral and/or topical (nasal skin) corticosteroids in three months preoperatively will be excluded.
