Etiology and Complications of Deep Neck Space Infections: A Hospital Based Retrospective Study.

Infections of the deep spaces of the neck often present a true clinical challenge to a Head and Neck surgeon which may rapidly spread due to the various connections between the spaces resulting in morbidity and mortality. This study aims to obtain knowledge about various DNSI's and their predisposing factors.. It was a hospital based retrospective cross-sectional study done in Goa Medical College, India. A total of 300 patients who presented with DNSI's over the past 7 years were studied. Simple proportions and percentages were calculated and Chi-square test was used to study associations. A total of 300 patients were evaluated and male preponderance was seen. Most of the patients were seen belonging to the pediatric age group (26%). Infections of dental origin (45.67%) were the most common etiological factor associated with poor oral hygiene and tobacco chewing (12.67%). Major comorbidities were anemia (34%) and diabetes (19.3%) which were directly related to the complications. The most common complication was airway compromise (14.66%) which was treated by tracheostomy. DNSI should be treated like a medical as well as a surgical emergency which can be life-threatening especially in diabetics and elderly who are immunocompromised and need special attention. Odontogenic infections associated with poor oral hygiene and tobacco chewing could be prevented by educating the population about oral hygiene.
