In the first of a two-part series, we review issues pertinent to the anatomy, embryology, and criteria for comprehensive management of children with microtia. The salient aspects of external ear anatomy, including the nerve and blood supply, lymphatic drainage, and aesthetic anatomic relationships, are described. An overview of the embryologic development of the external and middle ear and its ...

SUMMARY A subset of patients presents with unilateral conductive hearing loss, a normal pinna or grade I microtia, and mild external auditory canal stenosis. The physical findings of microtia and a small external canal are commonly absent or subtle in this group of patients, who are being commonly referred for imaging to evaluate isolated conductive hearing loss. We present a case series of pat...

Mastocytosis refers to a heterogeneous group of rare disorders characterized by an abnormal accumulation of mast cells in one or more organ systems. Cutaneous mastocytosis (CM) is the most frequent form in children and is characterized by hyperpigmented macules or papules symmetrically distributed over the trunk, and less so over the limbs, neck, and scalp. Two published articles have reported ...

At the present stage of development maxillofacial surgery, treatment patients with defects in auricles is one most difficult. Defects auricles, characterized by its absence, are divided according to etiological factor into two main groups: congenital (microtia) and acquired (as a result injuries various origins). Microtia (including anotia complete absence auricle) malformation auricle external...

Background: Microtia is a congenital abnormality of the auricle. One important comprehensive management microtia ear reconstruction. Reconstruction using an auricle framework from autologous material originating rib cartilages still gold standard. However, currently, some surgeons prefer alloplastic materials which are claimed to reduce morbidity and can be performed at younger age. Objective: ...

OBJECTIVE To compare the auricular projection results across 3 different techniques of sulcus construction in microtia repair (using a temporoparietal fascial flap, a retroauricular fascial flap from the mastoid region, or a superficial muscular aponeurotic system advancement flap). METHODS All the patients had been photographed at least 3 months after the second stage (construction of the re...

Microtia é uma deformidade congênita da orelha em que a estrutura externa é subdesenvolvida ou completamente ausente. A deformidade pode estar presente em uma ou ambas as orelhas e muitas classificações existem para o tipo de deformidade presente e tipo de reconstrução possível. Reconstrução autógena concentra-se principalmente na concepção e construção de uma estrutura a partir da cartilagem d...

OBJECTIVES An aberrant subarcuate artery (SAA) and its related canal are infrequent and asymptomatic. The presence of this variation may cause untoward hemorrhages, if accidentally nicked. Therefore, it is important for otologists to be aware of this entity, and its relative anatomy, to avoid any unexpected complication. We present a case of a 7-year-old girl who presented with right-sided micr...
