Abstract
Nasal dermoid sinus cysts (NDSCs) are rare neoplasms in the median line of the nasofrontal area. Unlike other dermoid cysts, a NDSC can manifest as a cyst, sinus, or fistula, and may extend intracranially. Nasal dermoid cysts usually present at birth and are commonly diagnosed by 3 years of age. An incidentally detected nasal dermoid cyst in an adult patient is extremely rare. In this case, a 23-year-old female with a history of intermittent serous thick discharge from a pit in the nasal columella since early childhood. Examination of the nasal cavity showed mild septal deviation to the left side, dorsal hump, wide nasal bone, a small pit-sinus at the columella, over projected nose, and wide bulbous down rotated nasal tip. The findings were suggesting nasal dermoid cyst, so a magnetic resonance imaging (MRI) was done for the patient to confirm the diagnosis. The MRI findings showed that there are 3 small cysts at the nasal septum anteriorly with a small fistula connecting the anterior inferior 2 cysts with no involvement to the intracranial cerebrospinal fluid (CSF) space. During the surgery, an open rhinoplasty approach was used. The trans-columellar incision was made around the fistula, and the tract was identified using a lacrimal probe and methylene blue. The dissection around the tract was continued until the sac was identified in the area of the membranous septum, and it was removed and sent for histopathology. The surgery then continued in a regular full rhinoplasty fashion. In conclusion, dermoid cyst of the nasal septum is a rare congenital lesion, especially in adults. After a thorough history taking and physical examination, a preoperative high-resolution axial and coronal CT and/or MRI is essential for diagnostic and operative planning. The treatment of choice for nasal dermoid cysts is complete surgical excision with clear margins. Surgical strategies usually depend on the location and extent of the lesion. Recurrence is uncommon and often easily managed.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
