is there a condition where the skull gets slimmer and makes the face look long neck long?

Yes, a condition known as acromegaly can lead to changes in facial structure, including a longer appearance of the face and neck. This condition is caused by excess growth hormone, often due to a pituitary tumor, leading to abnormal bone growth and thickening of the skull. Other conditions like craniOSynostosis or certain syndromes can also affect skull shape and facial proportions, resulting in a longer appearance.
