Resection of Inverted Papilloma of the Maxillary Sinus via a Prelacrimal Recess Approach: A Multicenter Retrospective Analysis of Surgical Efficacy.

Conclusions These multicenter follow-up results demonstrated that the PLRA is a safe and effective method for the excision of primary or recurrent IPMS with lower postoperative complications and recurrent rate.

Role of Superantigens in Allergic Inflammation: Their Relationship to Allergic Rhinitis, Chronic Rhinosinusitis, Asthma, and Atopic Dermatitis.

Conclusion Just as SAgs are known to feature in many allergic conditions, they play their part in AR, chronic rhinosinusitis, asthma, and AD. Further research is required before the relationship between SAgs and allergy can be adequately explained.

Odontogenic Maxillofacial Space Infections: A 5-Year Retrospective Review in Navi Mumbai

Abstract

Purpose

The aim of this study is to comprehensively review and analyse pure odontogenic maxillofacial space infections in a tertiary care hospital in Navi Mumbai over a period of 5 years.

Methods

A retrospective analysis of 315 patients treated at Dr. D. Y. Patil Dental College and Hospital at Nerul, Navi Mumbai, from January 2007 to December 2011 was done. Multiple variables were analysed. Localised infections like dentoalveolar infections without space involvement and infection of non-odontogenic cause were excluded from the study.

Results

Analysis of the records was done. Majority of patients were from lower socioeconomic background and were daily wage workers who had either consulted a general physician or a general dental practitioner or had self-medicated themselves before presenting to us with acute symptoms. Early recognition and prompt treatment involving intravenous antibiotics with extraction of involved tooth/teeth and incision and drainage helped in resolution of infections in a span of 72 h. Medically compromised patients had longer duration of hospital stay as compared to the patients who had no underlying medical condition. Majority of space infections involved multiple spaces and local anaesthesia with sedation was found to be the satisfactory mode of anaesthesia. Complications were very few.

Conclusion

We concurred that any form of odontogenic maxillofacial space infection should be rendered prompt and aggressive treatment and hospitalisation should be recommended wherever required.

Interaural Time Difference Perception with a Cochlear Implant and a Normal Ear

Abstract

Currently there is a growing population of cochlear-implant (CI) users with (near) normal hearing in the non-implanted ear. This configuration is often called SSD (single-sided deafness) CI. The goal of the CI is often to improve spatial perception, so the question raises to what extent SSD CI listeners are sensitive to interaural time differences (ITDs). In a controlled lab setup, sensitivity to ITDs was investigated in 11 SSD CI listeners. The stimuli were 100-pps pulse trains on the CI side and band-limited click trains on the acoustic side. After determining level balance and the delay needed to achieve synchronous stimulation of the two ears, the just noticeable difference in ITD was measured using an adaptive procedure. Seven out of 11 listeners were sensitive to ITDs, with a median just noticeable difference of 438 μs. Out of the four listeners who were not sensitive to ITD, one listener reported binaural fusion, and three listeners reported no binaural fusion. To enable ITD sensitivity, a frequency-dependent delay of the electrical stimulus was required to synchronize the electric and acoustic signals at the level of the auditory nerve. Using subjective fusion measures and refined by ITD sensitivity, it was possible to match a CI electrode to an acoustic frequency range. This shows the feasibility of these measures for the allocation of acoustic frequency ranges to electrodes when fitting a CI to a subject with (near) normal hearing in the contralateral ear.
