surgery/ ESS, functional endoscopic sinus surgery/ FESS, revision endoscopic sinus
surgery/ RESS are of interest to Dr. Kanit Muntarbhorn who reported FESS (Thai
patients) as early as 1987 AD.
Born in 1950 and worked as an associate professor, Dr. Kanit announces his retirement
on the web and hopes to use his experience to convey some messages to rhinologists, otolaryngologists, otorhinolaryngologists and endoscopic sinus surgeons in developing countries by reporting a “FESS and RESS” patient-symptom-orientated study which
has involved at least 10 years of his life.
Please note that, currently, Dr. Kanit Muntarbhorn does not attend outpatients to see or consult “ear, nose and throat” patients and does not perform sinus surgery anymore as
he has retired from medical practice. Furthermore, no hospital name will be mentioned
on this web-site for several reasons. Incidentally, any advice given to an imaginary
“adult patient” on this web-site is based purely on personal opinion; it should not be

FESS AND REVISION ENDOSCOPIC SINUS SURGERY:
PERSONAL EXPERIENCE OF MEDIUM-TERM AND LONG-TERM OUTCOMES

Kanit Muntarbhorn, Bangkok, Thailand

Introduction:

Before sinus surgery, patients diagnosed as having chronic sinusitis (rhinosinusitis) with or without nasal polyps may seek information on potential outcomes of Functional Endoscopic Sinus Surgery (FESS). Also, they may ask about Revision Endoscopic Sinus Surgery (RESS). So far, there is only a small number of reports on medium-term and long-term outcomes of symptoms according to questionnaires before surgery and 1 to 10 years after surgery.

This research involved “pre-FESS” and “post-FESS” symptomatic questionnaires including those of RESS cases. All patients were under care of one otorhinolaryngologist who performed all “FESS, ESS and RESS” operations and
who saw all patients at all outpatient attendences.

Objectives:

1) To obtain and analyze symptomatic outcomes in two groups of patients: (a) medium-term group i.e. MTG (follow-
up of 1-5 years) and (b) long-term group i.e. LTG (follow-up of 5-10 years),

2) To gather information on “RESS” cases, and

3) To gain information that may be useful for patient-doctor communication.

Subjects:

The following criteria were applied to 100 patients/subjects:

●      inclusion criteria of (i) adults of both sexes (aged 18 or more years), (ii) chronic sinusitis with or with out
nasal polyps, (iii) CT of paranasal sinuses and (iv) FESS with consent

●       exclusion criteria of (i) cases compatible with cystic fibrosis or immotile cilia syndrome, (ii) tumors e.g.
inverted papilloma, (iii) conventional or external or combined sinus operations rather than FESS and (iv)
cases with history of FESS/ESS/RESS by other surgeons.
