Oldest well‐preserved euprimate petrosal, from the early Eocene of India (Vastan Lignite Mine, Gujarat)

open access: yesThe Anatomical Record, EarlyView.
Abstract An exquisitely preserved, isolated partial petrosal with associated fragmentary stapes is described from the Vastan Lignite Mine (Gujarat, India), dated to the early Eocene (~54.5 Ma). Several anatomical traits (e.g., large petrosal plate; posterolateral entry of the internal carotid artery to the tympanic cavity; bony tubes surrounding the ...

Symmetrically dotted tympanic membranes [PDF]

open access: yes
Color changes of the tympanic membranes without an inflammatory component or perforation are rarely described. They may result from hemorrhage after barotrauma or spontaneously. Other explanatory models include discoloration due to otomycosis. This is a

Transcanal endoscopic excision of tympanic paraganglioma: A three-case series

open access: yesLaparoscopic, Endoscopic and Robotic Surgery, 2020
Paragangliomas are rare neuroendocrine tumors that arise in sympathetic and parasympathetic paraganglion system, derived from neural crest cells. Tympanic paraganglioma is a type of head and neck paraganglioma involving the middle ear cleft.

Clade‐wide morphological and functional variation of the sauropsid columella

open access: yesThe Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

Endoscopic evaluation of tympanic isthmus patency and its effect on success rate of myringoplasty in tubotympanic type of chronic suppurative otitis media

open access: yesThe Egyptian Journal of Otolaryngology
Background Chronic suppurative otitis media (CSOM) involves persistent middle ear inflammation, often leading to tympanic membrane perforation and hearing loss. Tympanic isthmus patency is key to middle ear ventilation, influencing tympanoplasty outcomes.

Doppler optical coherence tomography as a promising tool for detecting fluid in the human middle ear

open access: yesCurrent Directions in Biomedical Engineering, 2016
The treatment of otitis media requires classifying the effusion in the tympanic cavity for choosing appropriate therapeutic strategies. Otoscopic examination of the middle ear depends on the expertise of the physician and is often hampered in case of ...

Different shape but the same topographical complexity—The lingual gross anatomy of the Saimaa (Pusa saimensis) and Baltic ringed seals (Pusa hispida botnica)

open access: yesThe Anatomical Record, EarlyView.
Abstract Despite the distinctly different shapes of their tongues, the tongue gross anatomy of Saimaa ringed seal closely resembled that of Baltic ringed seal. There were no differences in the extrinsic and intrinsic tongue muscles or their associated vascularization and innervation between Saimaa and Baltic ringed seals.

The concept of an artificial tympanic membrane [PDF]

open access: yes, 1984
A review is given of the development of the concept of an artifical tympanic membrane. Starting with homologous tympanic membranes we compared biodegradable collagen materials (homologous and heterologous) and biodegradable synthetic materials, poly ...
