Cranial anatomy of the Duchesnean primate Rooneyia viejaensis: New insights from high resolution computed tomography.

Kirk EC1, Daghighi P2, Macrini TE3, Bhullar BA4, Rowe TB5.
Journal of human evolution.J Hum Evol.2014 Sep;74:82-95. doi: 10.1016/j.jhevol.2014.03.007. Epub 2014 May 22.
Rooneyia viejaensis is a North American Eocene primate of uncertain phylogenetic affinities. Although the external cranial anatomy of Rooneyia is well studied, various authors have suggested that Rooneyia is a stem haplorhine, stem strepsirrhine, stem tarsiiform, or stem anthropoid. Here we describe

A Jurassic mammaliaform and the earliest mammalian evolutionary adaptations.

Zhou CF1, Wu S, Martin T, Luo ZX.
Nature.Nature.2013 Aug 8;500(7461):163-7. doi: 10.1038/nature12429.
The earliest evolution of mammals and origins of mammalian features can be traced to the mammaliaforms of the Triassic and Jurassic periods that are extinct relatives to living mammals. Here we describe a new fossil from the Middle Jurassic that has a mandibular middle ear, a gradational transition

中耳炎手術と乳突蜂巣

中野雄一
耳鼻咽喉科展望 40(2), 220-226, 1997
最初の中耳炎手術である乳様突起単削開術から現在の鼓室形成術までを振り返ってその基本的手術操作をみると, それは病変を除去する中で, 乳突蜂巣の削開と掻爬が行われている。その結果, 慢性中耳炎に対する中耳根治手術では, 術後外耳道に広く開く削開腔が残ることになった。すなわち蜂巣構造の破壊とそれに伴う形態異常である。そこでこの削開腔をどのように処理するかで鼓室形成術にもいくつかの術式が生まれた。そのひ …

Ear Research Japan 17, 482-484, 1986
… The development of the external ear begins on the 12th day after gestation with the formation of the primitive external auditory meatus from the 1st branchial cleft. … On the 13th day, the meatus extends inwards to near the tubotympanic resess, and reaches the primitive middle ear adjacently on the 14th day. … On the 17th day, the canal stretches along the tympanic cavity and participates in the early formation of the tympanic membrane. …

… nerve was rapidly differentiated as the internal meatal, horizontal and vertical segments as with the development of the primordial stapes at the stage 17 and was gradually completed its normal running course by both the differentiation of the cartilagenous otic capsule and the pneumatization of the primitive tympanic cavity during the whole intra-uterine period.4) The development of the facial canal began as a sulcus on the canalicular division of the precartilagenous otic capsule at the stage …
