Adenoid Hypertrophy in Adults: Clinical and Morphological Characteristics
(Sage Publications Ltd, 2008) Yildirim, N.; Sahan, M.; Karslioglu, Y.
This study compared the aetiology and pathological characteristics of adult and childhood adenoid hypertrophy (AH). Clinical and morphological features and accompanying otolaryngological pathologies were recorded in 40 adults and 23 children undergoing adenoidectomy for obstructive AH. Both AH forms were similar in terms of symptomatology and associated inflammations. There were, however, significant differences in otitis media rate, with effusion and dullness, and retraction in the eardrum both more prevalent in childhood AH. Adult AH was associated with nasal septum deviation in 25.0% of patients. Histopathological features of adenoidal lymphoid tissue were dissimilar in the two groups: numerous lymph follicles with prominent germinal centres was the chief finding in childhood adenoids, whereas adult adenoids showed chronic inflammatory cell infiltration and secondary changes (e.g. squamous metaplasia). These results underline the importance of considering AH as a cause or contributing factor in nasal obstruction and related pathologies in adults and supports the theory that it represents a long-standing inflammatory process rather than being a novel clinical entity.
Delayed Surgical Treatment of Traumatic Hearing Loss Due To Ossicular Disruption
(Royal Belgian Soc Ear, Nose, Throat, Head & Neck Surgery, 2008) Yildirim, N.; Sahan, M.
Delayed surgical treatment of traumatic hearing loss due to ossicular disruption. Objective: Surgical treatment of dislocation and fracture of the middle ear ossicles is recommended to be carried out within months of the initial injury. Here we present 6 patients with traumatic ossicular injury whose surgery was delayed over I year. We evaluated the clinical and pathological changes that occurred over time and assessed the surgical outcomes in delayed cases. Methodology: Histories of the causative traumas, computerized tomography (CT) and tympanometry findings, pre- and postoperative hearing thresholds, and ossicular damages assessed at the tympanotomies were evaluated. Results: The time lapse between the trauma and the surgery varied from I to 6 years. The resultant hearing losses were moderate or moderately severe, conductive, mixed or sensorineural type. Tympanometry and CT revealed ossicular discontinuity in only two cases. In operations, various types of ossicular abnormalities in the form of absence, displacement, fracture and/or fixation were identified. Continuity and mobility of the ossicular chains were restored with various techniques. Air-bone conduction gap was brought to within 20 dBHL in all cases, and within 10 dB in 3 (50%) of the cases. Gains in the bone conduction were also notable. Conclusion: Trauma to the middle ear may result in an elevation in the air and/or bone conduction thresholds due to ossicular disruption and fixation. Our findings confirmed that tympanotomy is superior to methods such as CT and tympanometry in delineating the type and extent of the traumatic ossicular damage, and usually gives favorable results even in delayed cases.
