Referral Letter Guide

International expert opinion: to validate your surgical plan or obtain alternative technique recommendations. A written opinion from an academic head & neck surgical professor — an additional decision-support layer for your patient.

Complex surgery referral: situations where first-line treatment has failed — revision rhinoplasty (poor functional outcome after prior surgery), revision laryngeal/thyroid surgery, post-radiotherapy reconstruction. Detail: /ikinci-fikir.

Sub-specialist need: techniques not available at your center — transoral robotic surgery (TORS), papillary microcarcinoma active surveillance, microvascular free-flap reconstruction, complex lateral skull-base surgery.

Second opinion: post-biopsy diagnostic confirmation, NCCN/ESMO guideline-conformity check, supportive documentation before high-risk consent. Detail: /multidisipliner-tumor-konseyi for multidisciplinary decisions.

Multi-modality oncology case: holistic tumor-board decision for head & neck cancer — sequencing and selection of surgery + radiotherapy + systemic therapy. The Turkish center convenes the multidisciplinary team.

Unusual pathology or rare case: PRP studies, rare head & neck tumors (acoustic neuroma, juvenile angiofibroma), rare pediatric cases — literature review + specialist consultation.

Patient demographics: full name (per KVKK, full name required — abbreviations not accepted), date of birth, gender, nationality, current country. Contact info (phone + email) shared with patient consent.

Chief complaint: in the patient's own words. e.g. "I cannot breathe through my nose, worsening for 2 years." Duration (weeks/months/years) is important.

Treatments to date: which medications were tried (name + dose + duration + response), previous surgical procedures (date + by whom + what was done + outcome), physical therapy / rehabilitation, which centers evaluated the patient.

Comorbidities and systemic conditions: hypertension, diabetes, COPD, cardiac disease, renal/hepatic dysfunction, immunosuppressive therapy, anticoagulation, pregnancy, allergies (especially drug allergies).

ECOG performance status (for cancer cases): 0 (fully active, pre-disease performance) – 4 (bedbound). Critical for surgical candidacy and systemic-therapy selection. Karnofsky Performance Status accepted as alternative.

Current medication list: active medications (generic name + dose + route + frequency + start date). Anticoagulants (warfarin, DOAC), antiplatelets (aspirin, clopidogrel), immunosuppressants, chemotherapy regimen detailed.

Family history: cancer, thyroid disease, facial anomaly, hereditary hearing loss (especially in pediatric cases).

Social factors: smoking (pack-years), alcohol (units per week), occupation / voice use (teacher, professional singer), trauma history.

CT (Computed Tomography): paranasal sinus CT (sinusitis/rhinoplasty planning), contrast-enhanced neck CT (neck mass/lymph nodes), temporal-bone CT (otology/skull base), thyroid CT (non-contrast preferred, contrast complicates radioactive iodine planning).

MRI (Magnetic Resonance Imaging): contrast-enhanced neck MRI (parotid/submandibular tumors, skull-base/lateral skull-base pathology), brain MRI (acoustic neuroma, skull-base tumor, facial-nerve pathology), craniofacial MRI.

DICOM format: raw DICOM files preferred — uncompressed, ordered, correct patient labelling. JPG/PNG report images accepted but DICOM preferred (to enable 3D reconstruction).

Ultrasound: thyroid US (nodule characterisation — TIRADS classification), neck US (lymph node, cystic mass), salivary-gland US (sialolith/tumor). Share video recordings if available.

PET-CT: head & neck cancer staging, recurrence suspicion, primary-site search (CUP – cancer of unknown primary). SUV values and report details are critical.

Endoscopy images and videos: flexible nasopharyngoscopy, laryngoscopy (vocal-fold lesion assessment), ear otoendoscopy. High resolution for static images, 720p+ preferred for videos.

Cloud transfer: for data > 500 MB use an end-to-end encrypted cloud link (e.g. WeTransfer Pro, Tresorit, Dropbox encrypted folder). Files under 25 MB can be sent directly as email attachments.

Pathology report (PDF): original pathology report — diagnosis, staging (TNM), histologic grade, margin status, lymphovascular invasion, perineural invasion. Preferred language English; if original report is in another language an English translation is required.

Glass slide transfer: re-review of slides is frequently requested — especially for rare tumors, clinical situations conflicting with external pathology, second-opinion pathology consults. Slides shipped dry-stored + slotted box + non-cold-chain-required courier (DHL Medical, FedEx International Priority).

Paraffin block: for molecular testing (e.g. PD-L1, HPV, BRAF, EGFR, NTRK) or additional immunohistochemistry panels. A block provides more durable material than slides (new sections can be cut). Sent through hospital pathology under a "loan" procedure.

Immunohistochemistry panel results: critical for CUP (cancer of unknown primary), salivary-gland tumor typing, lymphoma sub-typing. p16 IHC (HPV+ oropharynx), thyroid panel (TTF-1, PAX-8, thyroglobulin), parotid panel.

Molecular test results (if available): HPV PCR/in-situ hybridisation, EBV (nasopharyngeal cancer), BRAF V600E (thyroid cancer), RET fusion (medullary thyroid cancer), NGS panel results. Raw data as PDF.

Re-evaluation time: 5-7 business days from slide/block arrival for re-review by a Turkish pathologist — a result pathology report + possible treatment-impact interpretation is shared as PDF.

Customs: glass slides and paraffin blocks are categorised as medical specimens — customs form declares "biological diagnostic specimen, no commercial value". The coordinator assists with the customs process.

Physician referral email: referral@profdrhasanahmetozdogan.com (once active; the main contact email is used temporarily — coordinator triages). Subject line: "Physician Referral — [Patient surname] — [Primary diagnosis]". Acknowledgement within 24 hours.

Tele-consult form: send via the "Physician referral" option on /tele-tip. Form fields: referring physician (your name/title/institution/country), patient summary, attached files, urgency level. The system auto-routes to the coordinator triage.

WhatsApp coordinator (for urgent matters): the coordinator number is open 24/7. Identify yourself as a physician ("Dr. X writing — patient referral"). Priority triage is applied for urgent oncology or life-impacting delays.

Secure file transfer: an end-to-end encrypted cloud link is provided for files over 25 MB. Written KVKK/GDPR consent from your patient (your center's form is accepted) must be obtained before data is processed in their name.

Physical letter (classic referral): in some situations a written referral letter is requested (especially treatment-targeted consults) — physical materials (including slides/blocks) can be shipped. DHL Medical Express, FedEx International Priority recommended.

Preferred channel for fastest exchange: 1) Tele-consult form (most structured), 2) Physician email (semi-structured), 3) WhatsApp (urgent only). Detail: /tele-tip.

0-24 hours — acknowledgement: receipt of referral, coordinator triage outcome, list of any missing info/documents, file-integrity check (does DICOM open, is pathology report legible). No clinical opinion at this stage.

3-5 business days — detailed clinical reply: for standard cases — clinical evaluation, imaging interpretation, pathology concordance, clinical Q&A. PDF written reply + optional 30-min video call. Response in English by default; report in another language adds 1-2 days.

7-10 business days — tumor-board decision: for complex oncologic cases, evaluation by the multidisciplinary team (ENT surgeon, medical oncology, radiation oncology, pathology, radiology). Written tumor-board report — treatment sequencing, alternatives, NCCN/ESMO concordance.

Within 24 hours — emergency triage: for life-impacting-delay scenarios (e.g. aggressive head & neck cancer, rapidly progressive vocal-fold paralysis, impending laryngeal obstruction), acknowledgement within 4 hours, emergency clinical opinion within 24 hours. Direction to your home-country emergency department is stated openly when needed.

Follow-up dialogue: 24-48 hour turnaround for additional questions/agreement after the clinical opinion. Most cases reach a decision in 2-3 written rounds.

All responses are written (PDF) and signed: signed by the Prof. Dr., dated and institutionally sealed. Formatted as an official document presentable to the patient and to their insurance company.

Encryption: all patient-file transfers end-to-end encrypted (AES-256 standard). Cloud links are one-time-use, with automatic deletion after download (24 hours). Email attachments only as password-protected ZIP (with the password sent via a separate channel).

KVKK (Turkey): explicit patient consent is mandatory — for any processing in the patient's name, written consent is required. Your center's "data sharing for international consultation" form is recognised under Turkish law.

GDPR (for EU country patients): under Article 9 (special-category health data) — explicit consent + lawful basis ("necessary for healthcare provision"). The patient's "data portability" right is preserved — data can be transferred or deleted on request.

HIPAA (for US patients): a "Business Associate Agreement" (BAA) is signed on request. HIPAA Privacy Rule-compliant processing — minimum-necessary principle; data-use limits clarified in the agreement.

Retention: active use during the treatment course; 10 years in archive after treatment (Turkish Ministry of Health requirement); after 10 years anonymisation for research use or full deletion (per patient preference).

Third-party access: tumor-board members (ENT, oncology, pathology, etc.) access on functional necessity — all members KVKK-trained + under confidentiality agreement. Third-party research/publication requires additional anonymisation + patient consent.

Data-breach notification: 72-hour requirement under KVKK/GDPR/HIPAA — if a breach occurs, written notification to you and your patient. Emergency action plan documented. Detail: /kvkk and /gdpr.
