Objectives:
This study aims to investigate whether the middle ear resonance frequency (RF) is affected in acromegaly, which causes growth in the skull bone.
Methods:
Thirty acromegaly patients and 38 volunteers were included in the study. Pure tone average scores and middle ear RF values of the groups that underwent pure tone audiometry, tympanometry, and multifrequency tympanometry tests were compared.
Results:
The pure tone mean was 14.95 ± 12.13 in acromegaly patients and 5.70 ± 8.52 in the control group (p:0.18). Sensorineural hearing loss(SNHL) was observed in 16.6% of the patients. The average middle ear RF was calculated as 815 ± 179.05 Hz in patients with acromegaly and 773 ± 127.15 in the control group. (p = 0.0001).
Conclusion:
This study is the first to evaluate middle-ear RF in acromegaly patients. Acromegaly-induced changes in soft tissues and bone structures impact middle ear functions. In this patient group, we found an increase in middle ear RF without conductive-type hearing loss and a 16.6% rate of SNHL.

01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
