안면 비대칭 환자의 진단분석에 이용할 수 있는 이하두정 두부방사선 규격사진과 표면 근전도 검사 자료는 통용화된 진단분석법 부재 등의 이유로 제한적으로 사용되고 있다. 그러나 여타 진단분석법과 비교할 때, 수직 안모 유형의 평가 등 차별적인 정보를 얻을 수 있어 이에 대한 연구가 필요하리라 보인다. 본 연구의 목적은 안면 비대칭을 보이는 60명을 대상으로 이하두정 두부방사선 규격사진 및 저작근의 표면 근전도를 측정하여 수직 안모 유형과의 연관성 및 안면 비대칭과의 연관성을 평가하고자 함이다. 이하두정 두부방사선 규격사진 계측치 중 radiographic corpus length는 비편위측이 큰 값을 보였고 (p<0.001), 유의성은 없었으나 gonion to interspinosum axis는 편위측이 크고, gonion과 하악과두의 위치는 비편위측이 편위측에 비해 전방에 위치하였다 (p=0.07). 안정시 편위측 전측 두근의 근활성은 비편위측보다 높은 것으로 나타났다 (p<0.01). 또한 최대 폐구 시 교근의 활성은 유의성이 없었으나 비편위측에 비해 편위측이 큰 값을 보였다 (p<0.09). Facial index와 intercondylar axes angle은 양의 상관관계를 보였다 (p<0.01). 최대 폐구 시 편위측 및 비편위측의 교근의 활성은 facial index와 양의 상관관계를 보였다 (p<0.05). 이상의 결과를 통해 골격성 안면 비대칭을 보이는 환자에서 이하두정 두부방사선 규격사진과 표면 근전도 검사를 통해 비대칭 양상의 평가와 더불어 수직 안모 유형의 평가 또한 가능한 것으로 생각된다.

Objective: To evaluate the short-term changes in masticatory muscle activity and mandibular movement patterns after orthognathic surgery in skeletal Class III patients with facial asymmetry. Methods: Twenty-seven skeletal Class III adult patients were divided into two groups based on the degree of facial asymmetry: the experimental group (n = 17 [11 male and 6 female]; menton deviation ${\geq}4mm$) and control group (n = 10 [4 male and 6 female]; menton deviation < 1.6 mm). Cephalography, electromyography (EMG) for the anterior temporalis (TA) and masseter muscles (MM), and mandibular movement (range of motion [ROM] and average chewing pattern [ACP]) were evaluated before (T0) and 7 to 8 months (T1) after the surgery. Results: There were no significant postoperative changes in the EMG potentials of the TA and MM in both groups, except in the anterior cotton roll biting test, in which the masticatory muscle activity had changed into an MM-dominant pattern postoperatively in both groups. In the experimental group, the amount of maximum opening, protrusion, and lateral excursion to the non-deviated side were significantly decreased. The turning point tended to be shorter and significantly moved medially during chewing in the non-deviated side in the experimental group. Conclusions: In skeletal Class III patients with facial asymmetry, the EMG activity characteristics recovered to presurgical levels within 7 to 8 months after the surgery. Correction of the asymmetry caused limitation in jaw movement in terms of both ROM and ACP on the non-deviated side.

Facial abscess is a suppurative condition that is caused by infection and that its infected materials built up within the loose connective tissues or a fascial space of the head and neck. Facial abscess should be treated with a caution since it can make threat to patient's life. When pus collects near masticatory muscles, it may lead to masticatory muscle disorder reducing the range of mouth opening and the mobility of jaw. The authors review an uncommon case of facial abscess which occurred in temporal muscle and induced mouth opening limitation.

Identification and protection of the facial nerve is very important in the proper operation of the parotid tumor. Posterior approach which finds main trunk of the facial nerve by surgical landmark such as tragal pointer, tympanomastoid suture, and posterior belly of digastric muscle is most commonly used. In case of posterior located tumor, inferior approach may be used, in which the retromandibular vein is followed from the neck and inferior branch of the facial nerve is located. In general, the facial nerve lies superficial to the retromandibular vein. But we experienced the anomalous relationship of the facial nerve and the retromandibular vien. We report this case with a literature review.

Background Static reconstruction surgery that tightens the tension of the inferior tarsus, thereby raising the lax lower eyelid, is a common treatment for paralytic ectropion of the lower eyelid. We present one such operative procedure, in which an orbicularis oculi muscle flap was used. Methods The surgical technique involves partial resection of the tarsus and the skin, as well as a superior-based orbicularis oculi muscle flap that is sutured to the firm tissue present on the Whitnall tubercle. The muscle flap is approximately 7 mm in width and 15 mm in length, with a superior pedicle that is attached to the tarsus at the medial point of the resected tarsus. The procedure results in contact between the ocular surface and the lower eyelid. Results The procedure was performed in 11 patients with lower eyelid ectropion due to facial paralysis. Ten cases showed a favorable outcome following surgery, with stable results seen over an average follow-up period of 4.5 years. In one case, recurrence of ectropion was observed 2 months after surgery due to an insufficient correction, and the patient required repeat surgery. Conclusions The orbicularis oculi muscle flap was an effective means of suspension and was able to maintain long-term traction tension. This procedure can therefore be considered a favorable treatment option for lower eyelid ectropion due to facial paralysis.

The aim of surgery for all parotid masses is directed toward total removal of the tumor with adequate safe margins of adjacent normal tissue and preservation of the facial nerve whenever possible. Reconstructive procedures following parotidectomy for benign or low grade malignant lesions are most commonly necessary if soft tissue deficits appear at the angle of the mandible below the earlobe as a major cosmetic deformity. This is a report of Z4 cases with a diagnosis of parotid tumor who were treated using various surgical procedures at Department of Plastic and Reconstructive Surgery, Hanyang University Hospital over the period of 4 years from January, 1983 to December, 1986. Among 24 cases, 11 cases were reconstructed by Sternocleidomastoid muscle flap at the same time that extirpative surgery is outlined. The advantage of Sternocleidomastoid muscle flap is the coverage of the facial nerve, so adhesion between the facial nerve and skin was prevented. Absorption and loss of bulk was not found such as dermofat graft. It was a simple method. Neither donor site defect nor sternocleidomastoid muscle deformity was developed. Sternocleidomastoid muscle flap have been found satisfactory in maintaining filled-out soft tissue hollows with good result cosmetically and functionally.

Congenital hypoplasia of the depressor anguli oris muscle is a rare cause of asymmetrical crying facies in newborns. The clinical manifestations range from mild to severe asymmetry and may persist up to adulthood. In the current case, the patient did not exhibit other congenital anomalies or paralysis of other branches of the facial nerve. This adult patient presented with severe asymmetrical lower lip deformity during full mouth opening since birth. A chromosomal study for the detection of 22q gene deletion yielded negative results. The electromyography findings of the lower lip were insignificant. Depressor labii inferioris muscle resection was not effective, but bidirectional (horizontal and vertical) fascia lata grafting improved the aesthetic appearance of the asymmetrical lower lip. The patient showed improved lower lip symmetry during full mouth opening at 1 year after the surgery. Therefore, the details of this rare case are reported herein.

Botulinum toxin type A (BTX-A) inhibits muscle contraction, which leads to reversible muscle atrophy and paralysis. Therefore, BTX-A injection can be an effective treatment of facial asymmetry that originated from the uncoordinated muscle movement. A 52-year-old patient was referred from another hospital for the correction of post-traumatic sequelae. The patient had prominent scar in the mandibular symphysis area with asymmetric lower lip movement. The reason for this asymmetric lower lip movement was due to damage in the lower lip depressor muscle. After the injection of BTX-A on the lower lip depressors, asymmetric lip movement has been improved.
