Background: This study aimed at determining the sociodemographic features, clinical presentation, indications, postoperative management and histological diagnosis of adult adenoid and tonsils tissues.
Materials and Methods: This was a retrospective hospital based study of adult patients who had adenoid and tonsils surgery. All the data obtained were collated and analysed using statistical package for social sciences (SPSS) version 18.0.
Results: The peak prevalence value was 32.1% at age group (21-30) years. Males accounted for 57.1% with a male to female ratio of 1.5:1. Common clinical presentation were difficulty/painful swallow ( 60.7%) and recurrent sore throat (48.2%). Major indications for surgery were recurrent tonsillitis (58.9%), peritonsillar abscess (14.3%) and tonsillar tumour (10.7%). Tonsillectomy(83.9%) was the commonest form of surgery in our study. Common histological outcomes of adenoid and tonsils specimens were reactive lymphoid hyperplasia/inflammatory (87.5%), squamous cell carcinoma (7.1%), lymphoma (3.6%) and adenocarcinoma (1.8%). Tonsillar and adenoid malignancy accounted for 8.9% and 3.6% respectively. The cellular types
found in Tonsillar malignancy were squamous cell carcinoma (3.6%), lymphoma (3.6%) and adenocarcinoma (1.8%). Adenoid malignancy was made up of squamous cell carcinoma (3.6%). Referral for chemoradiation therapy accounted for 12.5%.
Conclusion: Prevalence of adult adenoid and tonsillar malignancy was significant. Histological examination should be indicated for clinical presentation that are suggestive of malignancy or cases with unusual surgical pathology.
