A comparison of piezo surgery osteotomies with conventional internal osteotomies as performed by trainee surgeons: a cadaveric study

Double Lateral Osteotomy: Not Only the Correction of Crooked Noses but a Relevant Aesthetical Refinement in Structural Rhinoplasty

BACKGROUND

Osteotomy represents a crucial step in structural rhinoplasty; however, there is not a unique approach accepted. Double lateral osteotomy has proven to be effective in the long-term correction of a deviated nose. In this series, we evaluated its aesthetic value also in non-deviated cases.

MATERIALS AND METHODS

864 patients who underwent primary structural rhinoplasty from 2012 to 2020 were divided into four groups. Group A and B included patients with a crooked nose treated with asymmetrical double osteotomy and bilateral double osteotomy, respectively. Patients who did not present nasal deviation were divided into group C, including cases treated with bilateral single osteotomy, and group D, including patients who underwent bilateral double osteotomy. Postoperative evaluations were performed by three independent plastic surgeons blinded to the surgical technique. Patient's satisfaction was assessed through the FACE-Q rhinoplasty module.

RESULTS

FACE-Q scores reported a satisfaction rate higher than 30% for every item in all groups; however, group B and group D showed statistically higher satisfaction (p < 0.01). According to the evaluations performed by physicians, group B and group D showed the most satisfactory outcomes (p < 0.01).

CONCLUSIONS

bilateral double osteotomies represent a significant aesthetic refinement in structural rhinoplasty, not only in crooked noses but also in non-deviated cases, since the reduction in the width of the nose is an aesthetical aspect very appreciated by patients.

Efficiency-Efficacy Assessment of External Lateral Osteotomy Technique Versus Internal One in the Rhinoplasty

In this study we aimed to compare external lateral osteotomy technique vs. internal one in the rhinoplasty. In this before-after clinical trial study 30 patients who were candidates for rhinoplasty involved. In each patient, external lateral osteotomy was performed on one side and internal lateral osteotomy was performed on the other side randomly. Information, including patients' age, sex, grade of edema and ecchymosis 1, 3, and 7 days after the surgery, and the type of lateral osteotomy, the amount of step deformity, the need for the specialist intervention, nasal bone mobility, and flail nasal bone was recorded and analyzed. The incidence of edema and ecchymosis on the first and the third day was statistically lower in the external method (P value < 0.001). Although the incidence of edema and ecchymosis on the seventh day was lower in the external method, it was not statistically significant (P value > 0.05). Forty seven percent of patients in the internal method and 36% of patients in the external method had step deformity (p value < 0.001). Fifty percent of patients in the internal method and 41% of patients in the external method needed the specialist intervention (p value > 0.05). Seventy four of patients in the internal method and 83% of patients in the external method had nasal bone mobility (p value > 0.05). Out of 30 patients, only one had flail nasal bone. Based on our findings, the external technique is suggested as a more effective and convenient method with less complications for inexperienced surgeons.
