Microtia is associated with all except:
Deformity of the cochlea. This is not associated with microtia. Microtia is hypoplasia of the external ear with an incidence of approximately 1:5000, more commonly occurring on the right. The inner ear is rarely involved, but conduction deafness is often found. Treatment can be with a prosthesis which can be glued on or osseointegrated (Branemark®), or through ear reconstruction.
With or without cleft palate is different in aetiology to isolated cleft palate.
Pfeiffer syndrome consists of all except:
Cleft palate. This is not present in Pfeiffer syndrome.
Strategies for preventing complications in suturebased otoplasty include all except:
Use of a polyglycolic suture material. This is incorrect; polyglycolic sutures are dissolvable and a permanent suture should be used for pinnaplasty. Common choices include Ethibond® and clear Prolene®. A round-bodied needle prevents possible chondral microfractures from cutting needles along which sutures can pull through. A postauricular fascial flap can be based posteriorly 1 or anteriorly 2. Brown forceps prevent damage to cartilage during manipulation.
In cleft surgery, the following is true:
Two methods of bilateral cleft lip repair include the Manchester repair and the Millard repair. Tajima, McComb and Matsuma are nasal repairs. Simonart’s band affects the upper lip.
