An overall rate of 2.3% for major surgical complications and an overall rate of 16% for minor surgical complications suggest that cochlear implantation is a relatively safe surgical operation in experienced centers. Most surgical complications are minor and can be managed with conservative treatment or minor surgical intervention. However, meticulous attention to surgical detail, especially handling soft tissues and leaving the posterior canal wall intact, and long-term follow-up are of paramount importance in minimizing the incidence of surgical complications.

Cochlear implantation is feasible in children younger than 2 years without significant surgical complications or particular tuning difficulties. Functional results 2 years after implantation were as good as or better than those of children who underwent implantation between ages 2 and 5 years.

Tracheostomy is more hazardous in children than in adults, and carries special risks in the very young. The past 20 years have seen a large shift in the age distribution of tracheostomy. Whereas formerly the operation was done largely for management of epiglottitis and laryngotracheobronchitis, today the prime indication is subglottic stenosis in infants consequent upon intubation for respiratory distress syndrome and prematurity. We have reviewed experience with 57 tracheostomies in 56 children under 12 years old managed from a university hospital. All operations were done as elective procedures, in standard fashion, by otolaryngologists. Forty (70%) were in children under 1 year old, the indications being upper airways obstruction (41), failed extubation (11), and long-term assisted ventilation (5). Subglottic stenosis was the commonest cause of obstruction (21 operations). In 91.4 accumulated years with a tracheostomy there were 11 complications related to tracheostomy, one of which (a blocked tube) was fatal. Thirty-nine children were decannulated, the mean duration of cannulation being 21 months. In this series we suggest that the low morbidity and mortality rates were due to management by otolaryngologists; to postoperative intensive care; and, for the majority cared for at home, to careful education of parents and visits by specialist nurses.

Tracheostomy has, in the past, been performed in the majority of children under one year with bilateral vocal fold paralysis. We present our experience of 11 cases over a ten-year period during which tracheostomy was avoided whenever possible. Ten cases were managed conservatively but in the youngest a tracheostomy was required. Full bilateral vocal fold mobility developed in all cases at a mean age of 11.5 months (range 5–26 months). Our experience suggests that the airway can commonly be managed expectantly without a tracheostomy.

Tonsillectomy, adenoidectomy and adenotonsillectomy are among the commonest surgical procedures undertaken in children. The notes of 413 consecutive children having tonsillectomy, adenoidectomy or adenotonsillectomy were analysed retrospectively to determine complication rates. Of the total number of children, 5.6% had at least one complication, the most common of which was haemorrhage occurring as a first complication in 3.9% (16 children). Three children with bleeding required active treatment (0.7%), one requiring transfusion and two requiring a return to theatre, all within 3 1/2 hours of operation. The incidence of reactionary bleeding was not associated with the grade or seniority of the surgeon. Six children (1.5%) developed a fever post-operatively, of which one required antibiotic treatment. On the basis of these results it is feasible for such procedures to be carried out on a day-care basis.
