Difficult intubation--when can we predict it?
(17/37)
Anaesthetists at times encounter difficult intubation in an apparently normal individual in spite of using the best possible positioning and most profound relaxation. This study was carried out to find out the most simple and easy measurement that may predict a difficult intubation. The study was conducted in three groups of patients of twenty each. The first group consisted of patients in whom intubation was easy. Second group consisted of anticipated difficult intubation. Cases in whom very difficult intubation was encountered were analyzed retrospectively and were included in third group. An attempt has been made to predict difficult intubation with the roentgenographic study of lateral view of mandible along with the measurement of distance from chin to thyroid cartilage. Of all the parameters, ratio of effective mandibular length to posterior mandibular depth and distance from chin to thyroid cartilage were found to be important to predict difficult intubation.

A metrical study of the laryngeal skeleton in adult Nigerians.
(20/37)
Laryngeal cartilages were studied in 40 dissection room specimens of adult age groups ranging from 17 to 50 years in both the sexes. Various dimensions of the laryngeal skeleton were measured and statistical analysis of the data for male and female were evaluated separately. Conspicuous and highly significant differences of the dimensions between male and female laryngeal cartilages were observed. The incidence of the cuneiform cartilage and cartilago triticea was greater in the female than in the male. (+info)
Tongue Base Reduction with Thyro-Hyoido-Pexy (TBRTHP) vs. Tongue Base Reduction with Hyo-Epiglottoplasty (TBRHE) in mild-severe OSAHS adult treatment. Preliminary findings from a prospective randomised trial.
(21/37)
In a preliminary prospective randomised study, a series of 5 patients submitted to classic Tongue Base Reduction with Hyo-Epiglottoplasty (TBRHE according to Chabolle et al., 1998) is compared to a series of 7 patients submitted to a modified version of Chabolle's procedure. The changes introduced in the new surgical technique can be summarised as follows: a) lower neck skin incision; b) different neurovascular bundle identification; c) submucosal tongue base muscle resection; d) variation of the caudal hyoid stabilisation, already described by the Authors in 2008 (Tongue Base Reduction with Thyro-Hyoido-Pexy). The objective has been primarily to compare the feasibility, functional effectiveness and overall tolerability of the modified procedure. In this preliminary study Tongue Base Reduction with Thyro-Hyoido-Pexy has proven to be an easy and rapid procedure, with shorter post-operative functional recovery and comparable polysomnographic and neuro-psychological short time results.
