General Anaesthesia & Deep Sedation
Whether the clinic documents treatment under general anaesthesia or deep / twilight sedation — "sleep dentistry", where the patient is asleep and unaware (does not feel, see, or hear the procedure). Ordinary conscious sedation, where the patient stays awake and responsive, does not count here. This is informational and does not affect the transparency score.
- ✓ General anaesthesia / deep sedation (sleep dentistry) — General anaesthesia / deep sedation documented OMFS practice: major operations (jaw fractures, tumors) done under general anesthetic; routine outpatient surgery uses local +/- conscious sedation. [s1]

Change History
| Date | Change |
|---|---|
| 2026-10-01 | Re-checked 2026-10-01: the practice's Facebook page has no posts and no reviews, so an active Facebook presence is no longer recorded; WhatClinic profile re-read (5 verified reviews); Prof. Charles P. Sia rests on the practice's own website. |
| 2026-09-29 | Corrected 2026-09-29: no recurring complaints and no suspicious review patterns now unverified: 4 Google reviews are too few to show a pattern. |
| 2026-09-25 | Re-read on 2026-09-25: the practice's single-page website and its Google listing. Recorded: no prices published for any procedure on this surgical/implant specialist's site; Saturday hours and Sunday by appointment; virtual consultations and online booking via SeriousMD; no WhatsApp link; LocalBusiness structured data; no TripAdvisor presence. Still unverified: genuine premises photos, on-site CBCT, whether children's dentistry beyond surgical cleft care or emergency appointments are offered, and whether the practice answers reviews (the Google listing carries only 4). |
| 2026-08-25 | Re-verification 2026-08-25: website (csomfs.com) confirms this practice is now branded "Clinics of Oral and Maxillofacial Surgery" (Prof. Charles P. Sia), with BGC Taguig as primary location and Cebu as secondary — the Cebu Google Maps listing at the stored Queen's Rd/Redemptorist Drive address is now under the surgeon's personal name "Charles P. Sia, MD, MDS(OMFS)..." (category: Maxillofacial Surgeon) rather than "CPS Dental Surgery & Implant Centre", carrying a low 2.0 rating from 4 reviews. Corrected phone to +63 917 153 4500 (matches both website and Maps; stored +63 32 324 8804 could not be re-confirmed). Not permanently closed. Captured geo coordinates. |
| 2026-08-25 | Recorded sedation / general anaesthesia availability (informational): documented as available. OMFS practice: major operations (jaw fractures, tumors) done under general anesthetic; routine outpatient surgery uses local +/- conscious sedation. |
| 2026-08-25 | Removed manual red flag(s) no_doctor_credentials: they asserted unpublished licensing while the underlying data was unverified (null means "not checked", not "not published"). See methodology v1.3.0. |
| 2026-08-18 | Imported from the city-tier dataset. |
