The classification of hemifacial microsomia (HFM) aids in diagnosis, treatment planning, prognostic predictions and data evaluation. The aetiological and phenotypic heterogeneities of HFM, however, make its classification problematic The Kaban classification is a modification of the Pruzansky system, which characterizes the degree of mandibular involvement with particular attention to the ramus-condyle unit. The Kaban type I mandible has mild hypoplasia of the ramus-condyle unit; however, the temporomandibular joint functions normally Hemifacial microsomia also known as first and second brachial arch syndrome, oral-mandibular-auricular syndrome, lateral facial dysplasia, or oto-mandibular dysostosis is often a congenitally developed disorder.[6,7,8,9] Table 1 Signs and symptoms of hemifacial microsomia Table 2 Surgical procedure according to hemifacial microsomia type following the classification by Kaban, according to Liu et al, 2012 49 Surgical management of the mandible is essential, and mandible bone distraction has several advantages over costochondral graft Hemifacial microsomia is a congenital condition in which the tissues on one side of the face are underdeveloped. It primarily affects the ear, mouth and jaw areas, though it may also involve the eye, cheek, neck and other parts of the skull, as well as nerves and soft tissue. In 10 to 15 percent of cases, both sides of the face are affected.
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. Hemifacial microsomia and Goldenhar syndrome pose unique challenges to the craniofacial surgeon. The O.M.E.N.S. classifcation provides a description of the craniofacial features. For the M of O.M.E.N.S. (the mandible), the Pruzansky-Kaban classifcation provides therapeutic guidelines for joint and face reconstruction The wide spectrum of anomalies associated with hemifacial microsomia (HFM) has made systematic and inclusive classification difficult. We propose a nosologic system In which each letter of the acronym O.M.E.N.S. Indicates one of the five major manifestations of HFM Hemifacial Microsomia Hemifacial microsomia (HFM) is defined as a condition that involves an absence or underdevelopment of structures that arise from the first and second pharyngeal arches We thank Dr. Kaban et al. for their interest in our recent publication in Plastic and Reconstructive Surgery entitled The Mandibular Deformity in Hemifacial Microsomia: A Reassessment of the Pruzansky and Kaban Classification. 1 We appreciate their criticisms of our work. It is essential for all of us to continue to be critical of.
Hemifacial microsomia (HFM) is the second most common facial anomaly, with a broad spectrum of phenotypes. 1,2,3,4,5,6 Although it usually affects one side of the face, ears, mouth, and mandible, both sides are sometimes affected Hemifacial microsomia (HFM) is a congenital disorder that affects the development of the lower half of the face, most commonly the ears, the mouth and the mandible.It usually occurs on one side of the face, but both sides are sometimes affected. If severe, it may result in difficulties in breathing due to obstruction of the trachea—sometimes even requiring a tracheotomy

Most cases of this condition are sporadic, but there are rare.
In our department, the treatment for craniofacial microsomia has been based on the Kaban's modified classification. In type I, the management we use is orthopedic treatment to stimulate maxillary and mandibular growth. In type IIa and IIb we use distraction osteogenesis of the mandible and practice orthopedic treatment management at the same time The mandibular deformity in hemifacial microsomia: A reassessment of the Pruzansky and Kaban classification.

. Methods: This study included 249 Korean patients with HFM, whose charts, photographs, radiographs, and/or computed tomography scans acquired during 1998-2018 were available from Seoul National University Hospital and Dental Hospital Background Hemifacial microsomia (HFM) features hypoplasia and asymmetry in skeletal as well as soft tissue, and correction of the deformity is difficult in terms of aesthetic outcome. The purpose of this study is to examine the validity of an integrated treatment protocol for correction of this facial deformity. Patients and methods A retrospective study was performed on adult HFM patients. Hemifacial microsomia is the second most common facial birth disorder after cleft lip and palate, 34 with a prevalence of one in 3500 to 5600 live births. 35,36 Accepting these data, the number of patients in the studies was low. Major centers included less than 30 patients with hemifacial microsomia in their series (Table 1) Hemifacial Microsomia - Facial Palsy UK. There are several classification systems for hemifacial microsomia, which include: OMENS, Pruzansky and Meurman. Management of hemifacial microsomia is centred on a disciplinary team to correct ocular, mandibular, ear, facial nerve and soft tissue issues over a prolonged period of staged treatments

Whether facial asymmetry accounts for asymmetrical dental development is unknown. There are few data on dental development relative to mandibular development or severity of HFM, or on development over time most accurate clinical classification frame is, of course, the OMENS system, developed by Vento et al, thanks to a 1991 study on 154 patients affected with HFM. It focuses on each of the five Hemifacial Microsomia anatomic cases, according to Dysformia severity on a scale from 0 to 3.

A completely undeveloped pinna is referred to as anotia.Because microtia and anotia have the same origin, it can be referred to as microtia-anotia. Microtia can be unilateral (one side only) or bilateral (affecting both sides) Hemifacial macrosomia (HFM) is the second most common facial congenital anomaly. Deficiency of hard and soft tissue on one side of the face is its obvious clinical finding, which can cause facial asymmetry. Hemifacial microsomia is described in three grades of severity, although grade II has two subgroups (mild and severe). Many anomalies can be misdiagnosed with different grades of Hemifacial.
.In addition our patient also presented with additional clinical features consisting of an orofacial cleft, dermoids, brain anomaly, delay of motor and speech. Discussion. Hemifacial microsomia is a variable and asymmetric craniofacial malformation. Of all causes of asymmetry, it is the most unpredictable and widely variable in its expression and response to growth modification Hemifacial microsomia (HM) is a congenital craniofacial malformation caused by hypoplasia of anatomical structures deriving from the first and second branchial arches. As a result, HM involves facial skeleton, soft tissues, ear, and cranial nerves, thus resulting in the absence or insufficiency of these components  Craniofacial microsomia is a congenital facial malformation that commonly results in a decrease in the size of one or both sides of the mandible. The Pruzansky classification (1) and its 1998 modification by Kaban et al (2) is how plastic surgeons have classified and communicated the mandibular deformity in these patients almost universally. Hemifacial microsomia (HFM) is the most common craniofacial anomaly after cleft lip and cleft palate; this deformity primarily involves the facial skeleton and ear, with either underdevelopment or absence of both components. In patients with HFM, the management of the asymmetries requires a series of treatment phases that focus on their interception and correction, such as distraction.
Current research about hemifacial microsomia (HFM) patients after distraction osteogenesis (DO) most emphasize the morphologic changes. This case report shows the outcome of DO on the upper airway of a HFM patient with obstructive sleep apnea (OSA) based on the use of computational fluid dynamics (CFD). An 11-year-old boy was diagnosed as HFM with OSA, and underwent unilateral DO Hemifacial microsomia (HFM) is the second most common facial birth defect after cleft lip and palate.

The Pruzansky-Kaban classification of Hemifacial microsomia(15) describes 3 mandibular types based on the status of the condyle-ramus-glenoid fossa unit: type I (temporomandibular joint and ramus are well formed but smaller than normal), type II (temporomandibular joint, ramus, and glenoid fossa are hypoplastic and malformed, and sometime Hemifacial microsomia. Hemifacial microsomia ( HFM ) is the second most common congenital facial anomaly after cleft lip/palate. The condition may vary from mild to severe. Goldenhar syndrome has been described as a variant of HFM, in which vertebral anomalies and epibulbar dermoids were present 23. Kearns GJ, Padwa BL, Mulliken JB, Kaban LB.

Hemifacial Microsomia is part of a group of disorders collectively known as craniofacial microsomia. It constitutes the most common facial birth defect after cleft lip and palate The exact cause of Hemifacial Microsomia and its contributing risk factors are unknown OMENS classification of craniofacial microsomia was proposed by Vento et al. in 1991. Five major areas of involvement in craniofacial microsomia go by the pneumonic: O-orbital, M-mandibular, E-ear, N-facial nerve, and S-soft tissue
Hemifacial microsomia is the second most common facial birth defect after cleft lip and cleft palate. It occurs in approximately one in 3500-4000 live births. In children with HFM, part of one side of the face is small or underdeveloped. It usually affects the ear, mouth and jaw - and sometimes also the eye, cheek and neck Based on longitudinal observation of more than 80 patients, we concluded that mandibular hypoplasia is the earliest skeletal manifestation of hemifacial microsomia. The clinical defect becomes worse with time as a result of continued asymmetric growth and progressive secondary deformation of the midface. We hypothesize that midface growth is restricted by the hypoplastic mandible Hemifacial Microsomia from childhood to adolescence, placing special emphasis on the approach of the several classifications that try to specify the anomalies present in the HFM by atten-ding to the dysmorphologies in an isolated way (for example, only ear or jaw.), Or later modified by Mulliken and Kaban (1987). Other classi Various classifications have been developed to grade the degrees of hemifacial microsomia. Pruzansky described ear and mandible deformities into grades I to III. This case is an example of a Pruzansky IIb. 3D printing used in other walks of life is now used for modelling purposes prior to surgery. These are produced from the raw CT dataset Hemifacial microsomia (HFM) is associated with a difficult airway. We hypothesized that a difficult intubation would be predicted by radiographic evaluation of the severity of mandibular hypoplasia. A retrospective review of anaesthetic and surgical records of 102 children with HFM from 1986 to 1996 was conducted for radiographic classification of mandibular hypoplasia and degree of difficulty.
Numerous schemes have been developed to classify this spectrum. One of the most recent classification systems, the OMENS system, scores five clinical manifestations of hemifacial microsomia according to dysmorphic severity on a scale from 0 to 3: orbital asymmetry, mandibular hypoplasia, ear deformity, nerve dysfunction, and soft-tissue deficiency Hemifacial microsomia (HFM) is a congenital craniofacial malformation that features hypoplasia and asymmetry in skeletal tissue as well as in soft tissue .As HFM involves the structure of the first and second pharyngeal arches, it presents across a wide area, which includes the maxilla, mandible, external ear, middle ear ossicles, facial and trigeminal nerves, temporal bone, and muscles of. Hemifacial microsomia is a congenital condition where one side of the face is underdeveloped with the eyes, ears, cheekbone and mandible being affected. The lower half of the face is affected the most by this condition. Underdevelopment of the mandible includes underdevelopment of the TM joint.
