Proc Inst Mech Eng H 2021 Apr 23:9544119211011824. Epub 2021 Apr 23.

CNRS, Laboratoire Modélisation et Simulation Multi Echelle, MSME UMR 8208 CNRS, Créteil Cedex, France.

Osteotomies are common surgical procedures used for instance in rhinoplasty and usually performed using an osteotome impacted by a mallet. Visual control being difficult, osteotomies are often based on the surgeon proprioception to determine the number and energy of each impact. The aim of this study is to determine whether a hammer instrumented with a piezoelectric force sensor can be used to (i) follow the displacement of the osteotome and (ii) determine when the tip of the osteotome arrives in frontal bone, which corresponds to the end of the osteotomy pathway.

Correction of bony deviation in rhinoplasty.

Authors:
Kook Hyun Kim

Arch Plast Surg 2020 Nov 15;47(6):516-521. Epub 2020 Nov 15.

Human Plastic Surgery Clinic, Seoul, Korea.

In rhinoplasty, osteotomy is becoming more and more frequent as a way to achieve aesthetically pleasing and functional results, as well as patient satisfaction. In procedures to correct a deviated nose, osteotomy to correct the bone plays an essential role in addition to correction of the septum and cartilage, and osteotomy can reduce the wide nose bridge and give a slightly higher appearance in Asian rhinoplasty. However, osteotomy is relatively invasive, and the nasal bones of Asians are often low and thick, so bleeding or swelling during surgery can be somewhat more severe, and a stuffy nose can occur after surgery if osteotomy is performed incorrectly.

Correction of the deviated tip and columella in crooked nose.

Authors:
Man-Koon Suh

Arch Plast Surg 2020 Nov 15;47(6):495-504. Epub 2020 Nov 15.

JW Plastic Surgery Center, Seoul, Korea.

The primary procedural components of deviated nose correction are as follows: osteotomy to correct bony deviation, septal deviation correction, manipulation of the dorsal septum to correct upper lateral cartilage deviation, and correction of functional problems (manipulation for correction of internal valve collapse and hypertrophy of the inferior turbinate). The correction of tip and nostril asymmetry cannot be overemphasized, because if tip and nostril asymmetry is not corrected, patients are unlikely to provide favorable evaluations from an aesthetic standpoint. Tip asymmetry, deviated columella, and resulting nostril asymmetry are primarily caused by lower lateral cartilage problems, which include deviation of the medial crura, discrepancy in the height of the medial crura, and asymmetry or deformity of the lateral crura.

Charles East

Facial Plast Surg Clin North Am 2021 Feb;29(1):123-130

UCL, Rhinoplasty London, London SW1W 8TW, UK. Electronic address:

Crooked or deviated noses pose a specific challenge as many of the elements in a deviated nose are not symmetric and therefore not ideal for preservation techniques. Deviated noses are often where a hybridization between preservation and structural rhinoplasty is required. Careful preoperative evaluation of the soft tissue and bony anatomy of the patient is very important and congenital or post-traumatic asymmetry may involve more than the nasal pyramid. Read More

Piezoelectric Technology in Rhinoplasty.

Oral Maxillofac Surg Clin North Am 2021 Feb 3;33(1):23-30. Epub 2020 Nov 3.

Dental Research Center, Research Institute of Dental Sciences, Shahid Beheshti University of Medical Science, Tehran, Iran; School of Advanced Technologies in Medicine, Shahid Beheshti University of Medical Sciences.

Piezoelectric tools are the novel ultrasonic methods for effective and safe osteoplasty or osteotomy in comparison with traditional soft and hard tissue approaches using rotating instruments due to lack of microvibrations, ease of control and use, and safer cutting, mainly in complex anatomic areas. Piezoelectric indicates favorable and valuable outcomes based on the immediate postoperative morbidities, even though long-term results have not been investigated. It could be indicated that the piezosurgery in rhinoplasty can be considered as a reliable and safe method and should be taken into account as a part of the surgeon's repertoire for rhinoplasty.
