Paranasal sinuses and mastoid air cells have been attributed to multiple functions-such as voice resonance, cranial lightening, and pressure regulation-yet their potential role in local thermal homeostasis remains underappreciated. The thermoregulatory hypothesis, first proposed in the mid-twentieth century, was largely abandoned after the mid-century, when anthropological findings of climate-correlated variation...
No actionable change — this is a theoretical framework with no clinical evidence yet; practitioners should treat it as hypothesis-generating only.
If validated, this novel biothermal hypothesis could offer a new framework for understanding why some patients develop vestibular or ocular symptoms linked to middle ear and sinus pathology.
- 01Theoretical paper proposing skull pneumatization (air-filled cavities, sinuses, mastoid cells) acts as a biothermal protection system.
- 02Hypothesis links thermal regulation by skull air spaces to preservation of normal eye and balance (vestibular) function.
- 03No clinical trial or experimental data are presented; evidence is conceptual and anatomical.
- 04If correct, disruption of pneumatization (e.g., by chronic otitis media or sinus disease) could impair thermal homeostasis.
- 05Represents a novel but unvalidated theoretical framework requiring prospective study.
Skull pneumatization, including paranasal sinuses and mastoid air cells, functions as a biothermal system protecting ocular and vestibular homeostasis.
