중안면부의 골절은 심미적으로나 기능적으로 많은 문제를 야기할 뿐아니라 두개부와 연관되어 뇌손상의 가능성을 가지므로 생명과 직접적인 연관을 갖는다고 할수 있다. 산업사회의 고도의 발달로 인하여 자동차의 보급이 증가하고 그에 따라 교통사고의 절대수가 증가하고 안면부 골절환자가 증가추세에 있다고 볼 수 있다. 때문에 구강악안면외과의사로서 중안면부의 골절에 관심을 기울여야 할 것으로 생각된다. 중안면부 골절 가운데 비골을 포함한 안와 근심벽의 쉽게 일어나며 골절에 포함된 해부학적 구조물들이 복잡하기 때문에 골절후에 기능적 이상이 쉽게 발생될 수 있다. 본 과에서 처치한 중안면 골절 환자중 비골을 포함한 안와 근심벽의 골절환자를 경험한 바 이에 보고하는 바이다.

Various extraoral and intraoral approaches to reduction and fixation of zygomatic complex fractures were used. The method for exposure of inferior orbital area include the subciliary, inferior eyelid, infraorbital rim and conjunctions incisions. For exposure of frontozygomatic suture, lateral brow, coronal and b'ephaloplasty incisions were used. It is necessary that the usual approaches to the inferior and lateral orbit have two incisions. However, lateral canthotomy-conjunctival approach presented on this paper provide optimal exposure to lateral and inferior orbit.

It is important to choose which approaches should be used to correct the fracture if the operation is indication for surgery in patients with orbital floor fracture. Transorbital, transantral, and endonasal approaches are methods for correcting the orbital floor fracture. The approach needs to be considered the location of the fracture, the degree, the severity of the fracture, the least remaining patient's disability, and preference of the surgeon. We report a case of orbital floor fracture using transorbital approach and endonasal catheter ballooning to resolve the limitations of transorbital approach alone.

The nasal and zygoma bone are parts of frequently fracturing of facial bones because of anatomically protrusion. Of facial bone fractures, nasal bone is at the high level of incidence rate. But zygoma fracture that anatomical characteristics increase the incidence rate also is occupied considerable part of the facial bone fracture. The outline of face is decided by form of underlying skeletal structure, of that, zygoma plays an important role in. Zygoma is closely attached to surrounding anatomic structure as orbit, maxillary sinus. Aesthetic and functional disturbance are developed by zygoma fracture from trauma, complications, as facial asymmetry, trismus, sensory disturbance, epistaxis, periorbital hemorrhage, diplopia etc, are developed. The patterns of complications following displacement of fractured fragment of zygoma by trauma are slightly different.

Miniplate의 사용은 Champy등의 보고 이후 구강외과 영역에 있어서 외상 혹은 악교정수술등 많은 분야에 이용되기 시작했다. 전통적인 악간고정 방법에 비해 miniplate는 사용하기 쉽고, 정확한 해부학적 정복 및 고정을 가능케 하며 결과적으로 빠른 치유를 가능케 한다는 장점들을 갖고 있다. 그러나 감염, wound dehiscence, 부식, 나사의 헐거워짐, 주위조직의 변색 그리고 stress shielding effect등의 후유증들이 보고되어 왔으며 가장 무해한 금속이라고 알려진 titanium 또한 주위조직 및 lung, spleen, liver 그리고 kidney 등과 같은 조직으로 metal을 전이시키는 것으로 보고되고 있다. 특히 안와골 주변과 같은 상부 연조직이 얇은 곳에 miniplate를 사용할 경우 miniplate가 만져지거나 보일수도 있다는 점이 보고되었으며 따라서 술후 사용되었던 miniplate를 제거 해야만 할 것인가가 또한 주된 관심사로 보고되고 있다. 이에 저자는 이러한 금속성 miniplate의 단점을 개선하고자 자가 두개골을 이용한 플레이트를 고안하였다. '자가 두개골 플레이트'의 적응증은, enophthalmos 개선의 목적으로 두개골을 채취해 임플란트로 사용하는, enophthalmos를 동반한 관골 및 안와골의 복합골절환자에 있어 두개골의 추가채취가 가능한 경우가 될 수 있겠다. 자가 두개골을 이용해 플레이트를 고안하려고 본 증례에서의 시도는 구강외과 영역에 있어서 자가 두개골이 골편이 고정재료로도 쓰일 수 있다는 가능성을 보여주었다는 점에서 의미가 있다고 저자는 생각한다.

To avoid external facial scar which resulted from ordinary infraorbital and lateral eyebrow incision in surgical treatment of zygomatic tripod fractures, the author used intraoral incision and K-wire fixation method in 37 selected patients. This method contraindicated for the patient with multiple comminuted zygomatic fracture, patient combined with hard palatal fracture, and patient combined with herniated orbital floor fracture. The advantages of this method are simple, no external facial scar, and operate under direct visual field. The postoperative results were satisfactory. Balanced facial symmetry and good cosmetic results were obtained.

Background and Objectives : Pediatric orbital blowout fractures occur in discreet patterns, in reference to the characteristic developmental anatomy of the facial skeleton at the time of injury. The purpose of this study was to investigate the clinical characteristics, ocular symptom, fracture type and postoperative results of orbital blowout fractures in the pediatric population. Material and Methods : A retrospective study was conducted from January 2009 to June 2015 in 116 patients with orbital floor fractures ; all less than 18 years old. Patients were divided into 3 groups by age : 0 to 6, 7 to 12, and 13 to 18 years of age. The cause of fracture, fracture site and type, preoperative and postoperative ocular symptoms, timing of surgery were reviewed from their records. Results : Medial wall fractures were the most common site in the 0 to 6 years old group, and floor fractures were the most common site in other age groups. However, floor fracture was the most common site of the need for surgery in all age groups. Trapdoor type of fractures occurred more frequently than open door type of fractures in all age groups. Preoperative symptoms did not differ among the 3 age groups. In case of need surgery, frequency of preoperative ocular symptoms increased with age. However, as age group was young, rate of residual postoperative ocular symptoms were increased. Conclusions : The younger patients are more to have trapdoor type fracture and residual postoperative ocular symptom. Earlier surgical intervention more needed for children with entrapment results.

The relative position of the eyeballs in the orbit can be a criterion for estimating multiple pathological conditions. Especially, it is useful to diagnose orbital fracture, thyroid eye disease, orbital tumor, and to evaluate the result of drug and surgical treatment. The Hertel and the Naugle exophthalmometer, which are typical measuring instruments used mainly to measure the protrusion of the eye, are inevitably error by the measurer. In this paper, we propose a method to increase the accuracy and repeatability of the measurement of eyeball exophthalmometric values by using a white light interferometer.

The relative position of the eyeballs in the orbit can be a criterion for estimating multiple pathological conditions. Especially, it is useful to diagnose orbital fracture, thyroid eye disease, orbital tumor, and to evaluate the result of drug and surgical treatment. The Hertel and Naugle exophthalmometer, which are the most commonly used measuring instruments for measuring the prominence of the eye, are different from each other. Even if the same examiner repeatedly measures, it is inevitable. Also, even if the same exophthalmometer is different from the manufacturing company, the design of the fixed part of the orbit is different, and a measurement error is caused by the inspectors. In this paper, we propose a method of automatic measurement that can increase the accuracy and repeatability of measurement of exophthalmos using white light scanning interferometer, which is a 3D image measurement technique.

The relative position of the orbital eye can be a criterion for evaluating several pathological conditions. It is especially useful to diagnose orbital fractures, thyroid eye disease, orbital tumors and to evaluate the outcome of medication and surgical treatment. Hertel and Naugle are representative measurement tools used to measure eyeball protrusion values, and have different measurement results, such as fixed orbits, every time they are inspected, even if the same inspector repeatedly measures them. Even with the same calibrator, it is inevitable that different manufacturers will change the design of the stationary part of the orbit, causing the surveyor to make a measurement error. In this paper, we designed and fabricated a protrusion measuring device using a white light interferometer and measured the protrusion of the human eye and found that the precision and repeatability were significantly higher than the manual measurement method.
