INTRODUCTION: Superior semicircular canal dehiscence is a rare inner ear disorder characterized by an abnormal third opening between the superior semicircular canal and middle fossa. Symptoms include amplification of internal sounds, aural fullness, tinnitus, hearing loss, autophony, sound-induced vertigo (Tullio phenomenon), pressure-induced vertigo (Hennebert sign), disequilibrium, nystagmus, oscillopsia, and headache. While no cure exists for SSCD, surgical treatment has proven to effectively minimize these symptoms...

INTRODUCTION: Since 1996 the active middle-ear implant Vibrant Soundbridge (VSB) is used to treat mild-to-severe sensorineural hearing losses. The former standard surgical approach for incus vibroplasty included a mastoidectomy and a posterior tympanotomy, crimping the Floating-Mass Transducer (FMT) to the long incus process. The introduction of the short process (SP) coupler allows the attachment of the FMT to the incus body making the procedure of a posterior tympanotomy unnecessary...

The main causes of acquired auricular defects are surgical treatment of skin tumors and trauma. Due to the complex anatomy of the external ear, surgical reconstruction of defects in this area is challenging for surgeons, especially in case of midhelix-antihelix involvement with significant loss of soft tissue and cartilage. Our purpose is to illustrate the main reconstructive techniques of large midhelix and antihelix defects, as well as the advantages or disadvantages associated with each surgical procedure...

Endoscopic transcannal middle ear surgery via natural route allows minimal surgery procedure which avoids incision of auricula and protects mastoid air cells. Utilizing endoscope of different angles provides excellent views of the "hidden corner" in middle ear, therefore helping surgeons better get rid of reduce residual pathological tissues. Surgeons in otology should understand middle ear anatomy and physiology as well as master the use of endoscopic surgical instruments to perform procedures well...

Surgery aimed at hearing rehabilitation risks damaging residual inner ear function, especially cochlear implant surgery. Pharmacological intervention to reduce this risk has shown great promise in animal models. The challenge is to deliver medication to the appropriate part of the inner ear in appropriate concentrations for long enough to be effective. Barriers to achieving these goals include: the blood/labyrinth barrier, limiting systemic drug delivery to the inner ear, slow rates of diffusion from the base of the cochlea to the apex, limiting intratympanic delivery from the middle ear to the cochlear apex, delayed intracochlear fibrosis, requiring extended medication delivery postoperatively...

Perilymphatic fistula (PLF) is defined as an abnormal communication between the fluid (perilymph)-filled space of the inner ear and the air-filled space of the middle ear and mastoid, or cranial spaces. PLF is located in the round or oval window, fractured bony labyrinth, microfissures, anomalous footplate, and can occur after head trauma or barotrauma, chronic inflammation, or in otic capsule dehiscence. This clinical entity was initially proposed more than a century ago, yet it has remained a topic of controversy for more than 50 years...

Middle ear hearing reconstruction is unpredictable. Difficulties arise because of host factors, such as ventilation or scarring, surgical technique factors, such as prosthesis placement and stabilization, and design and mechanical factors influencing the properties of the prosthesis. Often there is a balancing act between choosing optimal stability, and maximizing the mechanical vibrations of the prosthesis. We review our and other investigators' work, in design and ideal placement of middle ear prostheses...

Giant cell tumor (GCT) is a benign tumor that originates from undifferentiated mesenchymal cells of the bone marrow. The cranium as well as temporal bone is a rare location for GCTs. Despite its benign nature, GCT may be locally aggressive and has the potential to recur locally. Furthermore, GCT may give rise to pulmonary metastases (~1%) in addition to causing local bone destruction. Surgical excision is the treatment of choice for patients with GCT. We describe the case of a 56-year-old female who presented with headache and hearing loss with extensive GCT, which originated in the squamous part of the temporal bone and extended into the left mandibular fossa and middle ear...

OBJECTIVE: Temporalis fascia is a commonly used graft material in tympanoplasty; however, little is known about how the histological structure of fascia remodels postimplantation. Herein, we aim to quantify the pre- and postoperative microstructure of temporalis fascia and compare histological findings to the native tympanic membrane (TM). METHODS: Temporal bone specimens having undergone successful subtotal or total drum replacement using temporalis fascia were identified (n = 3)...

BACKGROUND: Acute otitis media (AOM) is one of the most common childhood illnesses. While many children experience sporadic AOM episodes, an important group suffer from recurrent AOM (rAOM), defined as three or more episodes in six months, or four or more in one year. In this subset of children AOM poses a true burden through frequent episodes of ear pain, general illness, sleepless nights and time lost from nursery or school. Grommets, also called ventilation or tympanostomy tubes, can be offered for rAOM...

OBJECTIVES: To characterize anatomic variants of the external ear canal (EAC), specifically canal wall overhangs. EAC overhangs are problematic since they obstruct the view of the tympanic membrane (TM) and middle ear, possibly creating diagnostic and surgical difficulties. METHODS: We reviewed pre-operative temporal bone CTs from children with cholesteatoma, and no history of EAC erosion or surgery. We measured the anterior canal wall overhang (ACOH), inferior (ICOH), and posterior-inferior (PICOH)...

Generally, meningioma is considered intracranial lesion occurring in the intradural compartment. However, meningioma can also occur and usually confined in the extradural compartment called as primary extradural meningioma (PEM). PEM represents a special subgroup of meningioma constitute about 1% of all meningioma. PEM arises outside the subdural compartment and usually contains neither connection underlying subdural structures nor extends into with subdural compartment. It is commonly located in the paranasal sinus, middle ear, rarely in the intradiploic spaces of calvarial bone such as temporal, frontal, and parietal bone and orbit but extremely uncommonly in the occipital and sphenoid bones...
