How we do it: use of a venous cannulation needle for endoscopic Teflon injection to the vocal folds.

Since its introduction in the 1960's the injection of Teflon into a paralysed vocal fold has become a standard treatment in laryngology. Although in recent years alternative treatments have been suggested, such as the injection of collagen or autogenous fat (Mikaelian et al., 1991), re-innervation procedures and thyroplasty (Crumley, 1990), the use of Teflon is still widespread (Rontal and Rontal, 1991; Dedo, 1992). Various instruments have been developed for the application of Teflon paste and these take the form of a gun-like syringe with a ratchet mechanism. For a number of years we have injected Teflon using a needle marketed for internal jugular vein cannulation along with a plastic 1 ml syringe thus making substantial savings to our department in terms of both time and cost.

Concho-antropexy or total inferior turbinectomy for hypertrophy of the inferior turbinates? A prospective randomized study.

Twenty-five patients with bilateral nasal obstruction due to hypertrophy of the inferior turbinates were entered into a prospective study to compare the efficacy and the associated complications of total inferior turbinectomy and concho-antropexy. We found no significant statistical difference in the efficacy of these procedures in relieving nasal obstruction and discharge (p > 0.5). Total inferior turbinectomy was associated with more post-operative pain (p < 0.05) and with long-term dryness and crusting (p < 0.05) which were statistically significant. This is the first trial where concho-antropexy and total inferior turbinectomy are compared.

Glue under pressure: a bad prognostic sign for recurrence of otitis media with effusion.

One hundred and thirteen children with bilateral otitis media with effusion (OME) underwent myringotomy and insertion of Shah grommets. They were classified into three groups according to the presence or absence of 'glue under pressure' unilaterally or bilaterally. The follow up period ranging between 18 and 32 months determined the comparative rate of recurrence of OME and the number of grommet reinsertions. This study shows a significantly higher incidence of recurrent OME, requiring grommet reinsertion, in ears with glue under pressure (60 per cent) compared to those with glue not under pressure (7.4 per cent). Thus it was possible to identify a subset of children with OME who have a poorer prognosis for recurrence and who should be treated with long-stay grommets in the first instance.
