Background and ObjectiveaaTo begin with, an adenotonsillectomy is one of the most common operations in children who have been diagnosed with a condition of sleep-disordered breathing. Upon the preoperative evaluation of tonsil and adenoid size, it is important to predict the probable postoperative outcome. In this study, we investigated the correlation between the subjective tonsil grade, tonsil shadow area on skull lateral view radiographs, and tonsil volume after tonsillectomy. MethodsaaWe retrospectively reviewed the medical records of 234 patients who underwent an adenotonsillectomy in the tertiary referral hospital from January to June 2014. We demarcated the tonsil shadow area on the skull lateral view. When visible, the tonsil shadow area was considered as ellipse. The tonsil area was calculated by measuring the major (2a) and minor (2b) axes of shadow (S=πab). The tonsil volume was measured at the time of surgery. ResultsaaThe tonsil shadow was visible in 180 cases and invisible in 54 cases. The tonsil volume varied from 1.0 cm3 to 9.5 cm3. It is noted that the tonsil volume was significantly greater in the vis- ible group than in the invisible group, based on the lateral radiograph (3.81 ± 1.21 cm3, 3.24 ± 1.03 cm3, respectively; p = 0.002). In a review of the visible tonsil group (n = 180), there was a positive correlation between the tonsil shadow area and tonsil volume (r = 0.489, p < 0.001) and between tonsil grade and tonsil volume (r = 0.239, p < 0.001). ConclusionsaaTonsillar hypertrophy can be evaluated more accurately when using skull lateral view radiographs as compared with the use of a clinical examination. A tonsil shadow on skull lat- eral view can be a helpful, non-invasive, and relatively easy tool to predict tonsil volume in many cases.
