目的:比较不同类型的生殖器成形术技术(下巴前移,轮换和推进,挫折,和减少)在神经感觉缺陷和血肿形成方面。
方法:比较分析研究。研究的地点和持续时间:口腔颌面外科,武装部队牙科研究所,拉瓦尔品第,巴基斯坦,从2022年1月到2023年4月。
方法:纳入需要进行生殖器成形术并符合纳入标准的患者,即16-60岁的两种性别,并根据进行的生殖器成形术的类型分为4组。生殖器成形术按照矫形治疗计划进行,并在全身麻醉下进行。对8例患者进行了复位性基因成形术,对11例患者进行了进展性生殖器成形术,减少3例生殖器成形术,并在16例患者中进行旋转生殖器成形术。术后1个月随访通过主观和客观评估记录神经感觉缺陷,手术后第7天进行血肿形成的临床评估.
结果:旋转基因成形术显示神经感觉缺陷的频率最高(近50%),而减少型基因成形术显示神经感觉缺陷的频率最低(<1%,p=0.49)。在旋转基因成形术的推进中,血肿形成的频率最高(62.5%),在相等的回缩基因成形术中最低(25%,p=0.61)。
结论:与其他基因成形术技术相比,旋转基因成形术的术后神经感觉缺陷和血肿形成率最高。
背景:生殖器成形术,神经感觉缺陷,血肿,旋转生殖器成形术的推进,挫折生殖器成形术。
OBJECTIVE: To compare different types of genioplasty techniques (chin advancement, rotation and advancement, setback, and reduction) in terms of neurosensory deficit and haematoma formation.
METHODS: Comparative analytical study. Place and Duration of the Study: Department of Oral and Maxillofacial Surgery, Armed Forces Institute of Dentistry, Rawalpindi, Pakistan, from January 2022 to April 2023.
METHODS: Patients requiring genioplasty and fulfilling the inclusion criteria i.e. both genders aged 16-60 years were included and divided into 4 groups according to the type of genioplasty performed. Genioplasty was planned as per the ortho treatment plan and performed under general anaesthesia. Setback
genioplasty was performed on 8 patients, advancement
genioplasty on 11 patients, reduction
genioplasty on 3, and advancement with rotation
genioplasty on 16 patients. Postoperatively neurosensory deficit was recorded on follow-up after 1 month by subjective and objective assessments, and haematoma formation was assessed clinically on the 7th day after the procedure.
RESULTS: Advancement with rotation genioplasty showed the highest frequency of neurosensory deficit (almost 50%) and reduction type genioplasty showed the least frequency of neurosensory deficit (<1%, p = 0.49). The frequency of haematoma formation was maximum in the advancement with rotation genioplasty (62.5%) and minimum in equal setback
genioplasty (25%, p = 0.61).
CONCLUSIONS: Advancement with rotation genioplasty had the highest rate of postoperative neurosensory deficit and haematoma formation when compared with other techniques of genioplasty.
