Eyes in Ears: A Miniature Steerable Digital Endoscope for Trans-Nasal Diagnosis of Middle Ear Disease.

Ann Biomed Eng 2020 May 26. Epub 2020 May 26.

Vanderbilt University Engineering Department, Nashville, TN, USA.

The aim of this work is to design, fabricate and experimentally validate a miniature steerable digital endoscope that can provide comprehensive, high-resolution imaging of the middle ear using a trans-nasal approach. The motivation for this work comes from the high incidence of middle ear diseases, and the current reliance on invasive surgery to diagnose and survey these diseases which typically consists of the eardrum being lifted surgically to directly visualize the middle ear using a trans-canal approach. To enable less-invasive diagnosis and surveillance of middle ear disease, we propose an endoscope that is small enough to pass into the middle ear through the Eustachian tube, with a steerable tip that carries a 1 Megapixel image sensor and fiber-optic illumination to provide high-resolution visualization of critical middle ear structures.

A Novel Surgery Classification for Endoscopic Approaches to Middle Ear Cholesteatoma.

Curr Med Sci 2020 Feb 13;40(1):9-17. Epub 2020 Mar 13.

Department of Otorhinolaryngology, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, 430022, China.

This study aimed to develop a novel surgery classification for an endoscopic approach to middle ear cholesteatoma. We retrospectively analyzed the surgical approaches and outcomes of patients with middle ear cholesteatoma. Middle ear cholesteatoma surgeries were divided into four types and two special types as follows: type I, attic retraction pocket, which only requires tympanostomy tube placement or retraction pocket resection and cartilage reconstruction; type II, cholesteatoma which is limited to the attic or in which endoscopy can confirm complete removal of mastoid cholesteatoma lesions, including type II a, requiring only use of a curette, and type II b, requiring use of an electric drill or chisel; type III, cholesteatoma not limited to the attic, in which endoscopy cannot confirm complete removal of mastoid cholesteatoma lesions, requiring the combined use of endoscope and microscope to perform endoscopic tympanoplasty and "Canal Wall Up" mastoidectomy; type IV, extensive involvement of mastoid cavity cholesteatoma lesions and/or cases with a potential risk of complications, removal of which can only be performed under a microscope for "Canal Wall Down" mastoidectomy.

A nose out of joint: first reported case of prison-acquired marijuana-based rhinolith.

BMJ Case Rep 2019 Oct 25;12(10). Epub 2019 Oct 25.

Otolaryngology, Head and Neck Surgery, Westmead Hospital, Sydney, New South Wales, Australia.

Rhinoliths are calcareous concretions of the nasal cavity formed around a nidus that may be endogenous (eg, dislodged tooth) or an exogenous foreign body (eg, plastic bead inserted by a child). Rhinoliths are often found incidentally on endoscopy or imaging to assess for other pathologies. The incidence is estimated to be 1 in 10 000 of all otolaryngology outpatient presentations, but this is likely to be an underestimate due to the often asymptomatic nature of this condition.

Characterization of Anatomical Landmarks for Exposing the Internal Carotid Artery in the Infratemporal Fossa Through an Endoscopic Transmasticator Approach: A Morphometric Cadaveric Study.

World Neurosurg 2019 Nov 31;131:e415-e424. Epub 2019 Jul 31.

Department of Otolaryngology-Head and Neck Surgery, University of California, San Francisco, San Francisco, California, USA; Skull Base and Cerebrovascular Laboratory, University of California, San Francisco, San Francisco, California, USA. Electronic address:

Background: The Eustachian tube and sphenoid spine have been previously described as landmarks for endonasal surgical identification of the most distal segment of the parapharyngeal internal carotid artery (PhICA). However, the intervening space between the sphenoid spine and PhICA allows for error during exposure of the artery. In the present study, we have characterized endoscopic endonasal transmasticator exposure of the PhICA using the sphenoid spine, vaginal process of the tympanic bone, and the "tympanic crest" as useful anatomical landmarks.
