For most of the patients who suffer from obstructive sleep aponea, they have obstructions at multiple level and multiple sites, hence frequently require more than one procedures or even more than one stage of surgery to achieve satisfactory result.

After thorough assessment by history taking, physical examination, sleep study and endoscopic assessment of the obstructed airways, the sites of obstruction will be determined and are usually classified into nasal, velopharyngeal and hypopharyngeal levels, each require different procedures to overcome different patterns of obstruction.

Overview – correction of deviated nasal septum, commonly performed with turbinectomy in the treatment of nasal obstruction

Who need this operation – nasal obstruction as a result or partly contributed by deviated nasal septum

Overview – resection of hypertrophic turbinate to relief nasal obstruction. It is commonly performed with septoplasty to achieve satisfactory result.
Who need this operation – significant nasal obstruction as a result of turbinate hypertrophy

Overview – partial shrinkage of turbinate with laser technology.  This is a repeatable procedure and did not preclude more radical procedure like turbinectomy.
Who need this operation – nasal obstruction mainly contributed by turbinate hypertrophy

Overview – partial shrinkage of turbinate with radiofrequency technology. This is a repeatable procedure and did not preclude more radical procedure like turbinectomy
Who need this operation – nasal obstruction mainly contributed by turbinate hypertrophy

Overview – removal of adenoid tissue
Who need this operation – children suffering from OSA, or adults with significant adenoid hypertrophy causing velopharyngeal obstruction.

Overview – removal of the whole tonsils
Who need this operation – treatment of OSA in children, enlarged tonsils in adults, or as part of the procedure in UPPP and other more advanced  velopharyngeal procedures.

Overview – implantation of 3 short strips of artificial fibre into the soft palate, which will induce fibrosis and stiffening of soft palate 6 weeks after the procedure
Who need this operation – snoring and mild OSA patient with normal nasal passage, small tonsils, normal uvula, good depth and width at velopharynx

Overview – resection of uvula
Who need this operation – snoring and mild OSA patient with normal  velopharynx except long and thick  uvula
Surgical risk and possible complications – bleeding, pain, infection, regurgitation and recurrence of symptoms

Overview – a limited procedure on the soft palate mucosa to stiffen the soft palate and in a smaller extent pulling the uvula into a more anterior position
Who need this operation – patient with snoring and mild aponea with normal  velopharynx except a mild deficiency in depth

Overview – removal of tonsils and uvula and redundant soft tissue in velopharynx
Who need this operation – patient with enlarged tonsils and thick and long uvula causing velopharyngeal obstruction, or as an initial procedure for expansion sphincter pharyngoplasty, dorsal palatal flap and lateral pharyngoplasty

Overview – a procedure in the tonsil area aiming to deal with the lateral wall collapse
Who need this operation – velopharyngeal obstruction with lateral collapse

Overview – a procedure in the tonsil area aiming to increase the palatal height and width at velopharynx
Who need this operation – velopharyngeal obstruction with insufficient height and width of velopharynx

Overview – a procedure to the tonsil area aiming to increase the palatal width and height.
Who need this operation – velopharyngeal obstruction with insufficient height and width of velopharynx

Overview – by removing a 1 cm segment of bone from the posterior end of the hard palate, the soft palate was then reattached to the hard palate and creating a good depth for the velopharynx
Who need this operation – velopharyngeal obstruction with little depth but enough width
Surgical risk and possible complications – bleeding, pain, infection, regurgitaion,  recurrence of symptoms, oro-nasal fistula (very rare)

Overview – Laser removal of the uvula under local anesthetic
Who need this operation – snoring and mild OSA patient with normal velopharynx but excessively long and thick uvula

Overview – by employing radiofrequency technology to achieve volume reduction and stiffening in the soft palate with minimal pain, bleeding and ulcer
Who need this operation – snoring and mild OSA patients with normal velopharynx

Overview – the tongue and the epiglottitis was pulled forward to increase the depth of the hypopharynx

Who need this operation – patient with hypopharyngeal obstruction particularly with receding chin and a normal size tongue

Overview – an anterior neck operation aims to displace the whole tongue anteriorly and tilted slightly inferiorly, and fixed with stitches

Who need this operation – tongue base and hypopharyngeal obstruction with normal size tongue and chin

Overview – removal of tissue in the midline of the posterior third of tongue using radiofrequency plasma technology with removal of enlarged lingual tonsils

Who need this operation – hypopharyngeal obstruction with enlarged posterior third of tongue and  overgrowth of lingual tonsils

Surgical risk and possible complications – bleeding, pain, choking and aspiration, taste change and numbness in tongue

Overview – employing radiofrequency technology to achieve tongue base volume reduction with minimal pain and bleeding under local anesthesia. Multiple sessions are usually required to achieve satisfactory result

Who need this operation – patients with thick enlarged tongue

Surgical risk and possible complications – pain and bleeding are minimal. Ulcers are usually transient and small. Taste change and tongue numbness are rarely encounted.
