Summary
Smartphone otoscopy shows high diagnostic agreement with rigid otoendoscopy for middle ear diseases. This technology is feasible for clinical use, offering comparable results to traditional methods.
Area of Science:
- Otolaryngology
- Medical Imaging
- Digital Health
Background:
- Traditional otoscopy is a cornerstone in diagnosing tympanic membrane and middle ear conditions.
- Advancements in smartphone technology offer potential for novel diagnostic tools in otolaryngology.
Purpose of the Study:
- To evaluate the diagnostic agreement between smartphone-enabled otoscopy and rigid otoendoscopy.
- To determine the clinical feasibility of smartphone otoscopy for ear diseases.
Main Methods:
- A cross-sectional study analyzed 83 patient ear images using both smartphone and rigid otoendoscopy.
- Images were assessed by an otologist (gold standard) and secondary raters (ORL specialist, resident, GP).
- Diagnostic impressions were compared using Kappa coefficient and sensitivity/specificity analysis.
Main Results:
- High diagnostic agreement (Kappa=0.97) was observed between smartphone and rigid otoendoscopy.
- Smartphone sensitivity was 81.1% and specificity 71.1%; otoendoscopy sensitivity was 84.7% and specificity 72.4%.
- Image quality classification showed "Good" for 31.6% (smartphone) and 34.9% (otoendoscopy).
Conclusions:
- Smartphone-enabled otoscopy demonstrates high diagnostic agreement with rigid otoendoscopy.
- The findings support the feasibility and clinical utility of smartphone otoscopy for diagnosing ear conditions.
