The MRI scans of 108 patients referred to a regional Neurosciences Unit with a diagnosis of multiple sclerosis were examined. There were 71 females and 37 males with an age range of 22 to 67 years (mean: 39.7 years). The sagittal and axial images were reviewed and the degree of sinus disease noted. This was graded as absent, minimal, polypoid and pansinus. Fifty-seven patients (53%) had disease, the most common sinus involved was the maxillary followed by the ethmoid, frontal and sphenoid. Thirty-six patients had bilateral disease affecting the ethmoid sinuses most commonly. Three patients had fluid levels and four patients had retention cysts. The incidence of sinus disease is higher than in some other studies of normal populations.

Carhart&a... more Carhart's notch (CN) is a false depression of bone conduction (BC) thresholds at 2-4 kHz initially described in cases of stapes fixation. This study was designed to estimate the incidence and assess the clinical significance of CN in cases of otitis media with effusion (OME) in children. Clinical records of 50 patients of OME that showed CN were analysed, retrospectively. First 24 were identified as seen in outpatients and 26 were found out of 100 consecutive cases of OME. The criteria of CN were a minimum 10 dB depression in BC at any frequency 500-4000 Hz. Fifty patients showed CN, with mean age of 8.8 years. All had myringotomies with or without insertion of grommets. The CN ranged from 10 to 20 dB in the majority and up to 30 dB in few cases. In 85 ears studied, the affected frequencies comprised of 2000 Hz in 80 (94%), 4000 Hz in 4 and 1000 Hz in one ear. Pre-operative tympanograms were of type B in 68 (80%), type C in 16 (18.8%) and type A in one ear. Middle ear fluid was thick glue in 57 (67%), serous in 5 (5.8%), and no fluid found in 23 (27%) cases. Oedematous, granular or polypoidal appearances of middle ear mucosa were noted in 57 (67%) of the ears. A normal mucosa was seen in 17 (20%), and no details were available in 11 (13%) ears. Post-operative audiograms showed improvements of BC thresholds in 72 (84.7%) of the ears. Our results show 26% incidence of CN in paediatric cases of OME, with evidence of thick fluid and abnormal middle ear mucosa in about two-thirds of cases. This suggests that CN may be of prognostic value for myringotomy outcomes. Statistically there is a significant correlation between presence of fluid on myringotomy and CN, and type of tympanogram and post-operative BC threshold improvement. There is no predictive value of CN in terms of character of the middle ear fluid. Studies with larger numbers may be required to determine this with more certainty. It can help clinically, however, in pre-operative assessment of these cases. It is our opinion that BC should be an essential part of routine audiometry in all cases of OME.

Retrospective studies have been helpful in identifying some of the main problems responsible for many of our unsatisfactory results, both in the irradication of disease and the restoration of aural function. Prospective studies into the behavior of grafting materials for tympanic reconstruction in the experimental animal have led us to an overwhelming preference for natural materials as opposed to plastics or stainless steel. Both homologous and autologous bone and cartilage appear to offer good prospects in ossicular replacement techniques. The most satisfactory material we have used for repair of tympanic membrane defects continues to be either autologous or homologous temporalis fascia. The long‐term success of these materials in functional restoration is utterly dependent on continued aeration of the tubotympanic cleft.

Culture methods are not useful in characterisation of populations of bacteria in the middle ear. We have used a PCR-based method that does not depend on prior knowledge of the bacteria identified by culture.

Translations of the hieroglyphics depicted on all the illustrations accompanying previous publications do not substantiate this claim. The research presented is a result of an investigation of the original monument related to the doctor at its present location in the Egyptian Museum, Cairo. The research proves that Ni-Ankh-Sekhmet was the first rhinologist in history.

With increasing pressures on surgeons to audit existing practices and hence improve standards of health care, it is appropriate to produce such a set of guidelines for a surgery that is frequently performed worldwide. We believe that the data presented is not too exhaustive and can be readily incorporated into the operative notes.

Thirty-one ventilation tubes, including 21 Shah and six Shepherd tubes, that had been extruded naturally into the ear canal were examined. After formalin xation, material adhering to the tubes was retrieved and processed to paraf n wax. Five tubes were processed for scanning electron microscope (SEM) analysis. Sections were stained using histochemical methods for collagen, keratin and keratohyaline. In addition, the presence of collagen (type I and III), keratin, vimentin, bronectin, tenascin, factor VIII-related antigen, CD31 and CD45 was tested for by immunohistochemistry. Results showed that all specimens consisted of an acellular brous material, oriented in concentric rings parallel to the tube surface that was often associated with small collections of CD45 1 in ammatory cells. Two specimens contained collagen that was detectable by histochemical and immunohistological methods. Twelve specimens contained identi able desquamated epithelial cells containing keratin and keratohyaline. Only one specimen stained positively for connective tissue markers (vimentin, brous bronectin, tenascin) or showed the presence of vascular epithelium. SEM revealed adherent clusters or sheets of plate-like structures, consistent with the presence of epithelial squames, on three of the ve ventilation tubes examined. It is concluded that tissue retained on extruded grommets consists of orthokeratinitizing epithelium in ltrated by in ammatory cells, a nding that is consistent with the theory that tube extrusion occurs as a result of squamous epithelial proliferation, medial migration, differentiation and desquamation.

We present four cases that suggest that fine needle aspiration cytology followed by antituberculous therapy can avoid the need for surgery in this uncommon condition.
