Myringoplasty aims to reconstruct the tympanic membrane, restoring protection to the middle ear and improve hearing. Success of Myringoplasty in terms of anatomical closure is influenced by many factors. This study focuses on the influence of size and site of tympanic membrane perforation on success rate of Myringoplasty. This is a prospective study of 60 patients who underwent myringoplasty and were then followed up for 6 months from the date of operation. Patients with dry perforation, with good cochlear reserve, intact and mobile ossicular chain, functioning Eustachian tube were selected randomly for the operation...

REVIEW
Glenn Isaacson
Traditionally, otologists have aimed to produce a clean, dry, safe ear with the best possible hearing result. More recently, "less invasively" has been added to this list of goals. The development of small-diameter, high-quality rigid endoscopes and high-definition video systems has made totally endoscopic, transcanal surgery a reality in adult otology and a possibility in pediatric otology. This article reviews the anatomy of the pediatric middle ear and its surrounding airspaces and structures based on the work of dozens of researchers over the past 50 years...

This paper reviews the past and present developments in the treatment of chronic obstructive eustachian tube dysfunction. Alongside tube catheterization and bougie insertion, modern approaches such as laser eustachian tuboplasty and balloon eustachian tuboplasty (BET) are described. In BET, transnasal endoscopic insertion via the pharyngeal ostium places a balloon catheter in the cartilaginous portion of the eustachian tube. This is then dilated to a pressure of 10 bar for 2 min. Up until January 2013, 351 chronic obstructive eustachian tube dysfunction patients had been treated in our department using BET...

Eustachian tube dysfunction is closely related to the development of otitis media and result from several factors including inflammation within the nasal cavity and nasopharynx, adenoid hypertrophy, cleft palate and nasopharyngeal carcinoma. To some extent, eustachian tube dysfunction may be related to weakness of the paratubal muscles, such as the tensor veli palatini and levator veli palatini muscles. The aim of the study is to find out myogenic factors in eustachian tube dysfunction using electromyography (EMG), and to evaluate the clinical feasibility of EMG...

Epitympanic primary cholesteatoma represents a challenge for ENT surgeons. Its exact pathogenesis is still unknown because of the very complex anatomy of this region. Until now, only a few authors have described this region and tried to hypothesize the causes that could lead to cholesteatoma genesis. We hypothesize the existence of a selective dysventilation of the epitympanic region based on the presence of various mucosal folds occluding air ventilation from the middle ear to the epitympanum, through the epitympanic isthmus, causing a negative epitympanic pressure and consequently cholesteatoma formation...

Otalgia and/or impairment of hearing is one of the earliest, if not the first, symptom of certain pharyngeal and laryngeal disorders. Underestimation of these conditions or incorrect interpretation of their origin frequently lead to erroneous diagnosis and the wrong choice of treatment strategy. A total of 1074 patients with pharyngeal and laryngeal problems were available for examination that revealed pathologies in which otalgia and/or impairment of hearing is the first or an earlier symptom of the disease...

OBJECTIVES/HYPOTHESIS: Although middle ear aeration is certainly related to eustachian tube (ET) function, other anatomic factors may play an important role in ventilation of these spaces, particularly the epitympanum. STUDY DESIGN: A prospective case series study group with retrospective case series comparison. METHODS: Eight patients affected by non-self-cleaning attic retraction pockets or attic cholesteatoma of the middle ear and normal tubal function (verified by type A tympanogram or Williams' test) underwent endoscopic surgery...

Minimally invasive, in particular endoscopic treatment modalities are an important topic in medicine today. Over the last 15 years mini-endoscopy (ME) has been introduced and established in different fields of the head and neck region. ME includes endoscopy of the Eustachian tube, middle ear, lacrimal duct system and duct system of the major salivary glands. Direct visualization by endoscopy enables rapid, efficient and accurate diagnosis and treatment planning according to the findings. In the majority of cases simultaneous interventional therapy is possible...

Objective. Adenoid curette guided by an indirect transoral mirror and a headlight is a simple and quick procedure that has already been in use for a long time, but this method carries a high risk of recurrence unless done by a well-experienced surgeon. The purpose of this paper was to evaluate the efficacy of transoral endoscopic adenoidectomy in relieving the obstructive nasal symptoms. Methods. 300 children underwent transoral endoscopic adenoidectomy using the classic adenoid curette and St Claire Thomson forceps with a 70( composite function) Hopkins 4-mm nasal endoscope introduced through the mouth and the view was projected on a monitor...

OBJECTIVE: Cleft palates are strongly associated with the development of otitis media due to the anatomic and functional defect of the soft palate musculature and the associated alterations of velopharyngeal muscle insertion on tubal cartilage, or even intrinsic alterations of the cartilage, which affects eustachian tube function. This study will assess velopharyngeal muscle adequacy after palatoplasty through videonasoendoscopy and verify if there is a correlation with otologic status...
