Meatus is the Latin plural. Apparently, meatus or meatuses can be correct in English. "...the plural of meatus remains meatus in Latin or becomes meatuses in English..." Per http://www.dartmouth.edu/~humananatomy/resources/etymology.htm And also some references such as Dorland's state that the plural is also meatus. This appears to be one of those things that is changing over as doctors use it (correctly or incorrectly). Docs say meatuses per my personal experience.
Meatus is the singular. The plural form - which can hardly be necessary - would be meatus ( pronounced with a long last syllable "may-ya-TOOCE") in Latin, or simply meatuses.
The frontal sinus opens in the superior nasal meatus.
