Abstract

Objective: To investigate the treatment modalities (Tx-Mods) for patients with unilateral hemifacial microsomia (UHFM) according to Pruzansky-Kaban types and growth stages.

Methods: The samples consisted of 82 Korean UHFM patients. Tx-Mods were defined as follows: Tx-Mod-1, growth observation due to mild facial asymmetry; Tx-Mod-2, unilateral functional appliance; Tx- Mod-3, fixed orthodontic treatment; Tx-Mod-4, growth observation due to a definite need for surgical intervention; Tx-Mod-5, unilateral mandibular or bimaxillary distraction osteogenesis (DO); Tx-Mod-6, maxillary fixation using LeFort I osteotomy and mandibular DO/sagittal split ramus osteotomy; Tx- Mod-7, orthognathic surgery; and Tx-Mod-8, costochondral grafting. The type and frequency of Tx-Mod, the number of patients who underwent surgical procedures, and the number of surgeries that each patient underwent, were investigated.

Results: The degree of invasiveness and complexity of Tx-Mod increased, with an increase in treatment stage and Pruzansky-Kaban type (initial < final; [I, IIa] < [IIb, III], all p < 0.001). The percentage of patients who underwent surgical procedures increased up to 4.2 times, with an increase in the Pruzansky-Kaban type (I, 24.1%; IIa, 47.1%; IIb, 84.4%; III, 100%; p < 0.001). However, the mean number of surgical procedures that each patient underwent showed a tendency of increase according to the Pruzansky-Kaban types (I, n = 1.1; IIa, n = 1.5; IIb, n = 1.6; III, n = 2.3; p > 0.05).

Conclusions: These findings might be used as basic guidelines for successful treatment planning and prognosis prediction in UHFM patients.

根据Pruzansky-Kaban型和生长阶段对韩国单侧侧面小畸形患者的治疗方法。

目的:根据Pruzansky-Kaban型及生长分期，探讨单侧面肌短小症(UHFM)的治疗方法。方法:选取82例韩国UHFM患者作为样本。tx - mod定义如下:Tx-Mod-1，轻度面部不对称导致的生长观察;Tx-Mod-2，单侧功能矫治器;Tx- Mod-3，固定正畸治疗;Tx-Mod-4，由于明确需要手术干预而进行生长观察;Tx-Mod-5，单侧下颌或双颌牵张成骨(DO);Tx-Mod-6，上颌固定采用LeFort I截骨和下颌DO/矢状分叉支截骨;Tx- Mod-7，正颌手术;x- mod -8，肋软骨移植。调查了Tx-Mod的类型和频率，接受手术治疗的患者人数以及每位患者接受手术的次数。结果:Tx-Mod的侵袭程度和复杂性随治疗期和Pruzansky-Kaban型的增加而增加(初始<最终;[I, IIa] < [IIb, III]， p均< 0.001)。接受手术治疗的患者比例增加了4.2倍，其中Pruzansky-Kaban型增加了24.1%;活动花絮,47.1%;IIb, 84.4%;第三,100%;P < 0.001)。然而，根据Pruzansky-Kaban型，每位患者接受的平均手术次数呈增加趋势(I, n = 1.1;IIa, n = 1.5;IIb, n = 1.6;III, n = 2.3;P > 0.05)。结论:这些发现可作为UHFM患者成功治疗计划和预后预测的基本指导。

期刊介绍： The Korean Journal of Orthodontics (KJO) is an international, open access, peer reviewed journal published in January, March, May, July, September, and November each year. It was first launched in 1970 and, as the official scientific publication of Korean Association of Orthodontists, KJO aims to publish high quality clinical and scientific original research papers in all areas related to orthodontics and dentofacial orthopedics. Specifically, its interest focuses on evidence-based investigations of contemporary diagnostic procedures and treatment techniques, expanding to significant clinical reports of diverse treatment approaches. The scope of KJO covers all areas of orthodontics and dentofacial orthopedics including successful diagnostic procedures and treatment planning, growth and development of the face and its clinical implications, appliance designs, biomechanics, TMJ disorders and adult treatment. Specifically, its latest interest focuses on skeletal anchorage devices, orthodontic appliance and biomaterials, 3 dimensional imaging techniques utilized for dentofacial diagnosis and treatment planning, and orthognathic surgery to correct skeletal disharmony in association of orthodontic treatment.
