METHOD OF NASAL DORSUM BONES REINFORCEMENT BY THEIR FIXATION WITH SUSPENDED SUTURE Russian patent published in 2024 - IPC A61B17/24 A61B17/16 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, particularly to plastic, maxillofacial and ENT surgery. After the subperichondrium and subperiosteal detachment of the mucocutaneous flap, the upper bone portion of the nasal dorsum is removed by means of a piezoelectric apparatus, and the lateral, incomplete transverse and complete paramedial osteotomies of the nasal bones are performed. Then, in the upper bone part of the lateral slopes, a cone-shaped drill attachment of a piezoelectric apparatus for drilling bone tissue is formed by 2 holes on both sides. Groove is formed in the bone tissue in the area of the nasal root. Further, a continuous intercrossing suture is applied using a non-absorbable monofilament synthetic suture 4/0, starting from the caudal cartilaginous portions of the nasal dorsum towards the cephalic portions. At the level of the bone part, the needle is delivered through the pre-formed holes in the bone fragments through the septum from right to left and from left to right. Further, when the needle passes through the second holes in the bone tissue from the right to the left, the suture loop is placed into the formed groove in the area of the nasal root. Then nasal dorsum is stitched from cephalic parts to caudal ones. Further, an end portion of the nose is formed according to anatomical landmarks. Mucocutaneous flap is placed in place. Obtained aesthetic result is visually assessed and sutured. Intranasal splints are inserted into the nasal cavity and fixed with one interrupted suture, they are removed on an outpatient basis on the third day. Strip bandage is applied on the nose. External thermoplastic nasal splint is fixed, which is removed on an outpatient basis on 14th day.

EFFECT: method enables preserving stability of anatomical structures, creating the required width and height of the osteochondral vault of the nose in rhinoplasty.
