Silent Sinus Syndrome-A Rare Cause of Facial Asymmetry

The authors present a rare case of facial asymmetry caused by silent sinus syndrome in a 30 year-old man. Silent sinus syndrome consists of painless facial asymmetry characterized by unilateral enophthalmos. A discussion of the pathophysiology, management and current literature is included. This case serves to highlight the awareness that all clinicians dealing with the head and neck should possess.

Facial asymmetry with enlarged frontal sinus and hyperplasia of the cranial, nasal, and mandible bones.

The conditions of facial asymmetry are caused by congenital or acquired diseases, and several unclassifiable syndromes with unknown etiologies exist. In this report, a case of facial asymmetry with enlarged frontal sinus and hyperplasia of the frontal cranial bone and nasal bone is presented. Although the etiology of the facial malformation was clear, it was thought that the cause of the enlarged frontal sinus was related to the unidentified bony hyperplasia and facial asymmetry related to hemimandibular hyperplasia.

Orthognathic surgery associated with joint prosthesis in the treatment of facial asymmetry: case report

The asymmetric growth of the face may be triggered by skeletal congenital, genetic or traumatic as a result of injuries and fractures that impair mandibular growth. The correction of mandibular asymmetry aims to achieve, simultaneously, improve aesthetics and prevent jaw function, too, the recurrence of such a deformity. The cases of facial asymmetry are not easy to fix and do not always involve only the mobilization of a segment. However, an important part of orthognathic surgery. This study reports a case of mandibular asymmetry, exposing the possible causes for this deformity and the type of surgical treatment offered to order corrective surgery concomitantly.

Hiperatividade condilar: diagnóstico e tratamento - relatos de casos

INTRODUÇÃO: a hiperatividade condilar é uma condição causada por um desequilíbrio nos fatores de crescimento ósseo, gerando assimetrias faciais. Pode ser classificada em três tipos diferentes: hiperplasia hemimandibular (HH), alongamento hemimandibular (AH) e uma forma híbrida. O diagnóstico correto dessas hiperatividades é imprescindível, pois a abordagem é diferente para cada tipo de anomalia, tendo como opções o tratamento ortocirúrgico e a condilectomia alta. OBJETIVO: o objetivo desse artigo é, por meio de dois casos clínicos de assimetria facial causada por hiperatividade condilar, mostrar a importância de um correto diagnóstico e os meios utilizados para a obtenção do mesmo, visando um tratamento adequado para cada caso.

von Recklinghausen's disease (neurofibromatosis type I) is a chromosomal dominant hereditary disease, characterized by cafe-au-lait spots of the skin and multiple neurofibroma. Importantly, the neurofibroma arising in the oral and maxillofacial region is known to result in a jaw deformity. We report a case of facial asymmetry which may have been due to the neurofibroma of von Recklinghausen's disease and the repeated surgical intervention for it. The patient was a 20-year-old male. He had repeatedly undergone surgical extirpation of a tumor in the left parotid gland region since he was 3 years old. In the present findings, his face was asymmetric and his dental arch was narrow because of the mandibular deviation and the soft tissue mass in the left mandibular region. Radiographic examinations revealed a bone defect at the mandibular angle and atrophy of the left ramus. To improve these problems, distraction osteogenesis to expand the dental arches, and two-jaw surgery and iliac bone graft to restore the skeletal asymmetry were performed. Upon follow-up one year later, skeletal relapse was not noted.

Correction of a mandibular asymmetry using a custom-made titanium onlay

The diagnosis and treatment of facial deformities, including mandibular asymmetries, can pose a significant clinical problem. The limitations, accuracy and predictability of treatment options available and the expectations of the patient can further compound this. In this article we present a case of facial asymmetry secondary to mandibular angle deficiency corrected by the manufacture and placement of a custom-made titanium onlay. Although alternative methods were potentially available to correct this deformity, patient factors including occlusion, dental/skeletal relationship and chin position limited our options. Furthermore, construction of the custom-made titanium onlay involved the development of a computer-generated 3D virtual model and computer-aided design and computer-aided manufacture (CAD-CAM) of the inlay. This report demonstrates that this technique can be used successfully to address certain cases of facial asymmetry.

Unusual Foreign Body in the Nasal Cavity

Foreign objects frequently have been reported in the nasal structures, often these foreign bodies are occasionally inhaled by children or they are often inserted in nasal cavities after various accidents. Frequently, the presence of foreign bodies in the nose represents an emergency, particularly for pediatric patients where the incidence is high. The report in this article described an unusual nasal foreign body in an adult discovered incidentally during a cranial radiography. This report is an unusual case of facial asymmetry caused by a foreign nasal body in adult, which is destitute of complications, connected to long-term presence of the intranasal button. The finding was accidental; moreover the patient was an adult and did not present a clear symptomatology. Through careful clinical and fibroscopy exam, valuating also the site of the foreign body, it is necessary an intranasal surgery treatment. The results of the treatment is connected to a combined use of different branches of learning with the aim of obtaining positive results from both a clinical and legal point of view.

A novel method of quantifying facial asymmetry

There are two major issues in diagnosis of facial asymmetry. Firstly, the asymmetry commonly involves 3 dimensions. Secondly, there is difficult in quantifying the asymmetry. A method is developed using CT data, imaging processing program, and a new symmetry software to examine the asymmetry of facial skeleton in 3 dimensions, and to quantify and display the symmetry status with percentages and angles. The symmetry software involves automatic tracing of shape of bone structure and pairing the pixels on both sides. Symmetry value of 100% represents a mirroring symmetry. The clinical application of this method is demonstrated by a case of facial asymmetry.

Use of orthopedic finger distractor for facial asymmetry correction

Facial asymmetry after unilateral ankylosis results due to the loss of the condylar growth center on the ankylosed side. This results in the skeletal midline deviating to the affected side, a lack of vertical growth on the same side produces a cant of the occlusal plane and mandibular retrognathism is seen as a result of the hypoplasia. The lower border of the mandibular corpus and angle on the contra lateral side is usually flattened. We report a case of facial asymmetry following unilateral ankylosis, which was treated by a combined approach with distraction osteogenesis and orthodontics. Inexpensive orthopedic finger distractors were used. The facial changes were analyzed using the Grummons facial asymmetry analysis.

Most of the facial asymmetry cases are indications of orthognathic surgeries. However, in the case of patients refuse the treatment plan including a surgical component, the orthodontists try to correct the occlusion without surgical intervention. This case report describes a transfer patient of 12-years-old girl who exhibited mandibular asymmetry and had already commenced the orthodontic treatment with four premolars extraction. Our rediagnosis revealed the difficulty of correcting her skeletal problem only with orthodontic treatment. While we proposed a new treatment plan, she hoped for continuance without surgical procedure. We decided to continue the treatment and noted the following points to achieve minimum requirements in an occlusion.1. Geometrical relation between skull and mandible.2. Mandibular rotation resulted from growth and treatment.3. Limitation of upper anterior teeth movements by intermaxillary suture.An appropriate occlusion was obtained as a result of the precise mechanotherapy, and a good occulsal relationship had been maintained during the retention period.The patients worsen the facial asymmetry almost show some symptoms at the early mixed dentition. Therefore, careful observations and diagnosis are important before orthodontic treatments.

Correction of maxillofacial asymmetry using orthognathic surgical methods

A total of 20 patients with varying degrees of facial asymmetry were followed clinically and radiographically for at least 18 months after undergoing surgical correction. In 12 of the patients, the cause of asymmetry was hemifacial microsomia of varying severity. Infection of the TMJ in early childhood and irradiation damage were other causes of facial growth disturbance. Bimaxillary osteotomy was carried out in all cases and was often combined with resection of the coronoid process in order to lengthen the ramus. A postoperative jaw exercise programme has proved important as a means of maintaining or increasing mouth-opening capacity. The facial asymmetry cases are not easy to correct and are not always in line with expectations. However, they are an important part of maxillofacial reconstructive surgery.

顎変形症手術症例における顎関節症状の検討 第１報 多変量解析による分析

Skeletal malocclusion and orthognathic surgery may significantly influence the morphology and function of the temporomandibular joint and the position or direction of the mandibular condyle, thereby altering temporomandibular joint symptoms and signs or jaw function.Forty patients (15 males and 25 females, aged 18-36 years and followed for 18-46 months) with facial deformities and major malocclusions were studied. The subjects included 37 cases of mandibular prognathia, 10 cases of facial asymmetry and 7 cases of open bite. All cases underwent sagittal splitting osteotomy. Each patient was reviewed to elucidate the factors involved in temporomandibular joint symptoms and mandibular dysfunction by Type I and Type 11 quantitative theory.All signs and symptons of temporomandibular joint and mandibular dysfunction were recorded just before orthognathic surgery and at more than 18 months after surgery.Analyses were performed using the external criterion of ‘TMJ score’ for Type I quantification and three categories of external criteria (i. e., ‘no symptoms’, ‘mainly TMJ symptoms’.‘mainly muscle symptoms’) for Type II quantification. The explanatory variables were ‘surgical method’, ‘bone fixation’, ‘operator’, ‘increase of overjet’, ‘increase of overbite’, ‘increase of difference between upper and lower jaw midlines’, ‘presurgical mandibular deviation of jaw opening’, ‘presurgical TMJ sound’, ‘presurgical TMJ pain’ and ‘presurgical muscular pain’.The results were as follows:1. Type I quantitative theory analysis revealed that postsurgical TMJ scores were most closely related to the factor of ‘operator’, and strongly related to increase of difference between upper and lower jaw midlines.2. Type 11 quantitative theory analysis showed that the main symptoms of the cases were affected dominantly by the factor of ‘operator’, followed by the factors of ‘presurgical muscle pain’ and ‘increase of difference between upper and lower midlines’.3. Strong correlation of the ‘operator’ and ‘increase of difference between upper and lower midlines’ with temporomandibular joint symptoms and dysfunction suggests that technical factors of the surgical procedure and facial asymmetry significantly affect the quantity and quality of temporomandibular joint symptoms.

Use of a miniaturized detector in facial bone scanning

A high resolution cadmium telluride probe was used in conjunction with standard bone imaging methods in two cases of facial asymmetry. The probe improved localization of the abnormalities and led to rational treatment.
