Summary
Osteoma of the lamina papyracea can cause medial canthal pain. Endoscopic sinus surgery effectively relieved symptoms and prevented recurrence in a 74-year-old woman.
Area of Science:
- Otolaryngology
- Ophthalmology
- Neurosurgery
Background:
- Osteomas are benign bone tumors that can occur in the paranasal sinuses.
- Osteomas of the lamina papyracea are rare and can present with orbital or periorbital symptoms.
- Medial canthal pain can be an unusual symptom of osteomas in this location.
Purpose of the Study:
- To report a case of lamina papyracea osteoma presenting with medial canthal pain.
- To describe the successful surgical management of this condition.
- To review the literature on the pathophysiology of osteoma-related pain.
Main Methods:
- Case presentation of a 74-year-old woman with medial canthal pain.
- Surgical resection of the osteoma via endoscopic sinus surgery.
- Literature review on osteoma pathophysiology and pain.
Main Results:
- The patient experienced complete and prompt relief of medial canthal pain post-surgery.
- No clinical evidence of osteoma recurrence was observed at 12-month follow-up.
- The review highlighted potential mechanisms for osteoma-induced pain.
Conclusions:
- Endoscopic sinus surgery is an effective treatment for osteoma of the lamina papyracea causing medial canthal pain.
- Prompt surgical intervention can lead to significant symptom relief and prevent recurrence.
- Further research into osteoma pain pathophysiology is warranted.

01:30Bone Cells and Tissue
Bones contain a relatively small number of cells entrenched in a matrix of organic and inorganic components. Although bone cells compose only a small amount of the bone volume, they are crucial to its function. Four types of cells are found within the bone tissue— osteoblasts, osteocytes, osteogenic cells, and osteoclasts.
Osteoblasts and Osteocytes
The osteoblast is the bone cell responsible for forming new bone tissue. It is found in the growing portions of bone, including the periosteum and...

01:29Bone Formation by Intramembranous Ossification
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...

01:24Bone Formation by Endochondral Ossification
Bone formation, or ossification, begins around the sixth to seventh week of embryonic development. Most bones develop from a cartilaginous template through the process of endochondral ossification. Cartilage formation begins when clusters of mesenchymal cells differentiate into chondrocytes. These chondrocytes proliferate rapidly and secrete an extracellular matrix that becomes encased in a membrane called the perichondrium. The resulting cartilage model provides a template that resembles the...
01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
01:27Compact Bone
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

01:31Osteoclasts in Bone Remodeling
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
