The most popular approaches for vestibular schwannoma (VS) removal are retrosigmoid, middle cranial fossa and translabyrinthine (TL). All require a certain degree of invasivity, bone removal, or brain manipulation. Recently, the authors described the transcanal transpromontorial approaches (TTA), which allow the inner ear to be accessed directly through the external auditory canal (EAC), either with a microscopic (Expanded TTA, or ExpTTA) or even an exclusive endoscopic technique (Endoscopic TTA, or EndoTTA)...

Tympanoplasty was conventionally performed using a microscope for decades. However, since the endoscope began to be used in middle ear surgery in the 1970s, endoscopic tympanoplasty has gained increasing attention. The main objective of this study was to compare endoscopic and microscopic tympanoplasty with and without ossiculoplasty, demonstrating the potential advantages, disadvantages, and outcomes of each. This retrospective study included 126 patients with chronic otitis media who received tympanoplasty from 2013 to 2015 in our hospital...

OBJECTIVE: Making a 3-dimensional (3D) temporal bone model is simple using a plaster powder bed and an inkjet printer. However, it is difficult to reproduce air-containing spaces and precise middle ear structures. The objective of this study was to overcome these problems and create a temporal bone model that would be useful both as a training tool and for preoperative simulation. METHODS: Drainage holes were made to remove excess materials from air-containing spaces, ossicle ligaments were manually changed to bony structures, and small and/or soft tissue structures were colored differently while designing the 3D models...

OBJECTIVES: Endoscopic transcanal myringoplasty is a newly-introduced technique for reconstruction of tympanic membrane perforation that offers the advantage to obviate postauricular incision. The objective of this study was to evaluate the feasibility of a double-handed endoscope holder transcanal myringoplasty in children. This technique permits bimanual execution of the procedure and allows the surgeon to overcome the two significant issues of single-handed endoscope surgery, i.e. easy domination of a bloody field and smooth introduction of the graft...

Introduction Superior semicircular canal dehiscence syndrome was described by Minor et al in 1998. It is a troublesome syndrome that results in vertigo and oscillopsia induced by loud sounds or changes in the pressure of the external auditory canal or middle ear. Patients may present with autophony, hyperacusis, pulsatile tinnitus and hearing loss. When symptoms are mild, they are usually managed conservatively, but surgical intervention may be needed for patients with debilitating symptoms. Objective The aim of this manuscript is to review the different surgical techniques used to repair the superior semicircular canal dehiscence...

The retro- and hypotympanum are hidden areas of the middle ear, only poorly recognized. Nevertheless, this region is of relevant clinical significance, since it is regularly affected by disease such as cholesteatoma. The aim of this study is to explore and describe the anatomical variants of the hypo- and retrotympanum by the means of transcanal endoscopy. We hypothesize a significant variability of this hidden region of the middle ear. Moreover, we believe that the minimal invasive, endoscopic access is suitable since angled scopes may be used to explore the region...

Juveria Majeed, L Sudarshan Reddy
Chronic Suppurative Otitis Media (CSOM) is a chronic inflammation of middle ear cleft. It presents with discharging ear and decreased hearing. The diagnosis is mostly on clinical examination with otoscope or oto endoscope. Computerised Tomography (CT) of mastoids is done to evaluate the extent of the disease and its complication. High resolution CT is now the investigation of choice for temporal bone disease. This study emphasizes on the importance of CT scan in diagnosis of inflammatory ear diseases and most importantly identifying pitfalls or complications which a surgeon can come across during surgery...
