Dear Editor,

We would like to thank Dr. Liu for his interest in our study and also the relevant comments on our article “Frequency, location, and morphology of accessory maxillary sinus ostia: a retrospective study using cone beam computed tomography (CBCT)” [3]. We have gone through the comments carefully and we have understood that Dr. Liu was mainly questioning about the high frequency of accessory maxillary ostia (AMOs) of 47.2% reported in our article, which is higher than the one found by previous studies—for further information please refer to the “Discussion” section of the article mentioned above.

Dr. Liu mentions that this rather high percentage may result from inaccurate or false identification of AMOs, which could have resulted in an over reporting of AMOs. Furthermore, Dr. Liu argues that any extra opening of the maxillary sinus located outside the region of nasal fontanelle and hiatus semilunaris should not be termed as an AMO on the basis of the mainstream definition....
