    ABSTRACT: Although the anterolateral and anteromedial thigh flaps have such disadvantages as anatomical variations in the lateral circumflex femoral system and its cutaneous perforators, they have a sufficient number of cutaneous perforators on the anterior aspect of the thigh in many cases, meaning double anterior thigh flaps can be elevated from the ipsilateral thigh. We report 8 cases in which single-pedicle double anterior thigh flaps were transferred for reconstruction of head and neck defects following resection of head and neck tumors from January 1995 to March 2001 at Okayama Saiseikai General Hospital. Eight double anterior thigh flaps were classified into the following 3 types by perforator derivation: Type I flaps consisting of double anterolateral thigh flaps with a single vascular source were elevated in 4 cases. Type II flaps consisting of anterolateral thigh flap and anteromedial thigh flap supplied by separate branches from a single vascular source were elevated in 2 cases. Type III flaps, in which two anterior thigh flaps were harvested separately and constructed into a single flap with microvascular anastomosis, were elevated in 2 cases. Double anterior thigh flaps were combined with vascularized bone, and 2 flaps supplied by independent long vascular pedicles from a single vascular source could be 3-dimensionally arranged. All flaps completely survived in 7 cases and functionally and aesthetically acceptable results were obtained except in 1 case whose flap was lost to major necrosis after infection. We concluded that the single-pedicle double-flap technique using anterior thigh flaps is useful in 3-dimensional reconstruction of massive complex head and neck defects since sufficient tissue implant with preserved blood flow and free flap arrangement is made available.

    ABSTRACT: The benefits of plastination specimens in temporal bone surgery (TBS) were evaluated. A formalin-preserved human temporal bone was drilled and dissected with the middle cranial fossa approach or the translabyrinthine (or transcochlear) approach. The specimen was thereafter subjected to silicon impregnation. The flexibility of the dura mater after plastination was maintained, and not only bony structures such as the auditory ossicles and semicircular canals but also soft tissues such as the facial nerve, internal carotid artery and the sinus attached to the dura mater were easily discriminated. The technique furnishes a persistently dry, odorless and durable specimen that allows handling and may serve as the most ideal specimen for anatomical learning of various approaches of TBS.

    ABSTRACT: Eleven patients who had been surgically treated from 1988 to 1999 were retrospectively reviewed in order to evaluate the efficacy of ventilation tube insertion and mastoidectomy with, or without, mastoid obliteration for intractable middle-ear cholesterol granuloma. The mean age registered was 17.2 years at the time of surgical treatment. All cases were unilaterally affected. Five ears were treated with simple mastoidectomy coupled with the insertion of a ventilation tube, while six others had additional mastoid obliteration. The hearing prognosis was excellent with an improved post-operative hearing level of 16.5 dB (cf. pre-operative 37.7 dB). However, morphological prognosis revealed two ears had a residual perforated tympanic membrane without otorrhoea after displacement of the ventilation tube. Of the remaining nine ears with intact placement of the ventilation tube, five had dry ears while four had occasional otorrhoea. Although the morphological prognosis was incomplete, treatments involving at least an insertion of a ventilation tube with thorough mastoidectomy were thought to be necessary.
