Abstract Old rhinoplasty practice has been often relied on resection of the nasal framework in order to achieve aesthetic and/ or functional objectives. Nowadays, careful dissection, conservative resection, planned framework remodeling, & judicious use of properly selected grafts for augmentation comprise the basis for a structural approach to grafting in rhinoplasty. Aim of the work is to present and evaluate outcomes of using grafts in rhinoplasty. Grafts types, techniques were reviewed. Complications, if encountered, were mentioned. Patient satisfaction was evaluated. Methodology is a prospective study utilized the open rhinoplasty technique, upon 35 patients that suffered from various nasal deformities. Their ages ranged between 18 and 45 years. The followed principles consisted of: 1) A precise definition of the type and cause of abnormality. 2) Definition of the goals. 3) Adequate exposure. 4) Preservation or restoration of normal anatomy 5) Incremental and planned correction. 6) Maintenance of nasal airway. Results are 35 patients operated by the open technique, 23 were males while 12 were females. Of them, 32 cases were fully corrected while, 3 cases were partially corrected. Complications were minimal, occurred in 3 cases. The majority of cases (32 cases) were satisfied while 3 cases were unsatisfied. Conclusion is development of sophisticated grafting techniques has played an integral role in achieving durable aesthetic and functional surgical outcomes in rhinoplasty.

At that time, Egypt had a cases with psychic problem or cases generally unfit highly developed culture in art, literature and for surgery. science, the glory of which was medicine (Masters and Manchester, 1973). The Edwin Smith papyrus 25 patients (71.4%) were operated in AL-ZAHRAA from ancient Egypt outlines the diagnosis and Hospital, while 10 patients (28.6%) in a private treatment of nasal deformities 3000 years ago hospital. 30 patients (85.7%) were Egyptians while (Garrison, 1917). In 1898, Jacques Joseph, a 5 patients (14.3%) were from other Arab countries. German orthopedic surgeon presented his 24 patients (68.57%) were males and 11patients revolutionary concepts of nasal surgery to the (31.42%) were females. Medical Society of Berlin. He is considered by many rhinoplasty surgeons as the father of modern The principles that were followed in the work rhinoplasty (McDowell, 1952). Old rhinoplasty consisted of: 1) A precise definition of the practice has been often relied on resection of the abnormality present and the cause of these nasal framework in order to achieve aesthetic and/ abnormalities, as far as can be ascertained from or functional objectives. The resulted loss of preoperative examination.2) Definition of the goals structural integrity would often lead to poor to be achieved. 3) Adequate exposure of the durability of aesthetic outcomes and progressive deformity. 4) Preservation or restoration of normal functional impairment. This has called the need for anatomy 5) Incremental and planned correction of the development of grafting approaches in modern the specific abnormalities identified. 6) rhinoplasty. Nowadays, careful dissection, Maintenance of the nasal airway. conservative resection, planned framework History taking remodeling & judicious use of properly selected The patients were admitted, a detailed and thorough grafts for comprise the basis for a structural nasal history was obtained. A discussion about approach to grafting in rhinoplasty. Grafts are used patient motivations was carried out. Specific to reconstitute compromised supportive elements questions regarding previous trauma, previous nasal and to rebuild nasal framework in case of structural or sinus surgery, nasal allergy, tobacco, and drug deficiency in order to effect the desired change. use provide important information regarding nasal function.

Their Thorough clinical examination is done to all a cases ages ranged between 18 and 45 years (Mean age 32 including: years).

The sebaceous Cases excluded from the study: cases younger than gland concentration in the nasal skin is also noted, 18 or older than 45, if grafts no applicable, cases as are any scars or other asymmetries. The nasal valve is then observed during sniffing. The external 2 and internal nasal valves are then examined and The Cottle maneuver is performed in all patients evaluated. External valve collapse may be noted in with nasal airflow obstruction. This is performed by thin-skinned individuals with narrow nostrils. pulling the midfacial soft tissue laterally at the Collapse of the internal nasal valve is a much more common cause.
