Abstract
Introduction
Adenoidectomy is one of the most common procedures performed by otolaryngologists. Traditional adenoid curettage is performed blindly, which can result in inadequate removal of the adenoid and injury to the surrounding structures.
Objective
To perform transnasal endoscopic examinations to assess the nasopharynx after conventional curettage adenoidectomy.
Methods
The present prospective study included 100 children with a mean age of 4.2 ± 3.07 years. It is composed of two steps: conventional curettage adenoidectomy by a resident trainee; and endoscopic evaluation of the nasopharynx through a 0° telescope to assess adenoidal remnants, injury to the surgical field or adjacent structures, and bleeding points.
Results
Adenoid remnants were observed in 42% of the cases after conventional adenoid curettage in multiple locations, such as the roof of the nasopharynx over the choana (24%), the tubal tonsil (12%), the posterior pharyngeal wall (4%), and the posterior end of the nasal septum (2%). Injury to the surgical field and adjacent structures was observed in 46% of the cases (posterior pharyngeal wall: 23%; lateral pharyngeal wall: 11%; Passavant ridge: 10%; and the Eustachian tube orifice: 2%). Endoscopic bleeding was observed in 29% of the cases; 13% of the cases were from adenoid remnants, 10%, from the mucosa, and 6%, from the pharyngeal muscles. Bleeding was mild in 19% of the cases, moderate in 9%, and severe in 1%.
Conclusion
Endoscopic evaluation of the nasopharynx following conventional adenoid curettage provides important data regarding adenoid remnants, injury to the surgical field or nearby structures, and bleeding points, which aids in the provision of optimal care and in the achievement of a better outcome.
