Abstract
OBJECTIVE: To assess the efficacy of blind nasal intubation technique, in cases of ankylosis of temporomandibular joint (TMJ) without the facility of fiber optic bronchoscope. DESIGN: Analytical study. PLACE AND DURATION OF STUDY: Maxillofacial Surgery Department, Armed Forces Institute of Dentistry, Rawalpindi, Pakistan, from August 2002 to October 2003. PATIENTS AND METHODS: A total of 35 patients of ankylosis of TMJ were included in the study. Blind nasotracheal intubation technique was attempted after induction of anaesthesia and paralyzing the patients. Where blind nasotracheal intubation technique was not successful, one nasotracheal tube was passed into the esophagus and retained. Nasotracheal intubation was attempted through contralateral nares by second tube. RESULTS: Out of 35 patients male to female ratio was 1:1.2. The age of the patients ranged between 5 to 35 years with a mean age of 14.5 years. Blind nasotracheal intubation technique was successful in 23 cases (65.7%), whereas in 12 patients intubation was not successful. The 12 cases of failed blind nasotracheal intubation technique were successfully intubated nasotracheally by prior placement of nasotracheal tube into the esophagus through contralateral nares, which facilitated re-intubation (34.3%). CONCLUSION: In the selected patients blind nasotracheal intubation was facilitated by prior placement of the endotracheal tube into esophagus. This technique may be helpful in reducing the psychological trauma and complications of tracheostomy in such patients. However, to-date, fiber optic intubation remains the safest and widely accepted intubation technique in such patients.
