  • A Small Road to Misery in Necrotizing External Otitis
    Published August 8, 2019 as 10.3174/ajnr.A6161 ORIGINAL RESEARCH HEAD & NECK A Persistent Foramen of Huschke: A Small Road to Misery in Necrotizing External Otitis X W.L. van der Meer, X M. van Tilburg, X C. Mitea, and X A.A. Postma ABSTRACT BACKGROUND AND PURPOSE: Necrotizing external otitis is a serious complication of external otitis with different spreading patterns. A persistent foramen of Huschke is a dehiscence located antero-inferior in the osseous external ear canal and posterior-medial to the temporomandibular joint. This dehiscence can facilitate extension of infection in an anterior pattern next to classic spread along the fissures of Santorini. The aim of this study was to define the prevalence and size of a persistent foramen of Huschke in patients with necrotizing external otitis. MATERIALS AND METHODS: We retrospectively examined 78 CT temporal bone studies (39 patients with necrotizing external otitis, 39 control subjects). The side and presence of the foramen were noted, and its prevalence was calculated. The maximal width of the foramen of Huschke was measured in the axial plane and classified as subtle, mild, moderate, or extensive. RESULTS: A persistent foramen of Huschke was present in 21 patients (26 ears) and 7 control subjects (9 ears). Prevalence was 50% (20/40) and 11.5% (9/78) in affected ears of patients with necrotizing external otitis and control subjects, respectively. Almost all affected ears showed an anterior distribution pattern of necrotizing external otitis. The extensive dehiscence was most common in affected ears. CONCLUSIONS: An anterior necrotizing external otitis spreading pattern is associated with the presence and increased size of a persis- tent foramen of Huschke.

When present, it is on the anterior wall of the external acoustic meatus and is associated with important oto- logical complications of the temporomandibular joint and external acoustic meatus. To report on the incidence of tympanic foramen in adult dry skulls, belonging to the population of the Northeast of Brazil, 87 adult skulls obtained from the Human Anatomy Laboratory of 4 univer- sities of the Northeast of Brazil, without knowledge of gender, race and age were analyzed. The 174 temporal bones were examined for presence, morphology and measurements of the longi- tudinal and transverse diameter of the tympanic foramen.

  • Surgical Anatomy of the Temporal Bone Gülay Açar and Aynur Emine Çiçekcibaşı
    Chapter Surgical Anatomy of the Temporal Bone Gülay Açar and Aynur Emine Çiçekcibaşı Abstract Numerous neurological lesions and tumors of the paranasal sinuses and oral cavity may spread into the middle and posterior cranial fossae through the ana- tomical apertures. For the appropriate management of these pathologies, many extensive surgical approaches with a comprehensive overview of the anatomical landmarks are required from the maxillofacial surgery’s point of view. The surgical significance lies in the fact that iatrogenic injury to the petrous segment of the tem- poral bone including the carotid artery, sigmoid sinus, and internal jugular vein, can lead to surgical morbidity and postoperative pseudoaneurysm, vasospasm, or carotid-cavernous fistula. To simplify understanding complex anatomy of the temporal bone, we aimed to review the surgical anatomy of the temporal bone focusing on the associations between the surface landmarks and inner structures. Also, breaking down an intricate bony structure into smaller parts by compart- mental approach could ease a deep concentration and navigation. To identify the anatomic architecture of the temporal bone by using reference points, lines and compartments can be used to supplement anatomy knowledge of maxillofacial surgeons and may improve confidence by surgical trainees. Especially, this system- atic method may provide an easier way to teach and learn surgical spatial structure of the petrous pyramid in clinical applications. Keywords: maxillofacial surgery, segmentation, surface landmarks, surgical anatomy, temporal bone 1. Introduction The temporal bone is a dense complex bone that constitutes the lower lateral aspect of the skull and has complex anatomy because of the three-dimensional relationships between neurovascular structures.
