Posterior pharyngeal flap surgery is the most commonly used operation to restore velopharyngeal competence (i.e., develop a functional seal between the vocal and the oral cavity), and therefore correct hypernasality and nasal air escape (Ysunza et al., 2002).
Later, he tried to create this ridge by folding a flap of pharyngeal mucosa upon itself. This type of surgery is best for patients with velopharyngeal defects. (Peterson-Falzone et al., 2001) Cartilage implants: material, (usually from the patient's rib), is implanted to create an anterior projection on the pharyngeal wall.
Posterior pharyngeal flap surgery is mostly used for vertical clefts of the soft palate. The surgeon cuts through the upper layers of the back of the throat, creating a small square of tissue. This flap remains attached on one side (usually at the top). The other side is attached to (parts of) the soft palate.
When a pharyngeal flap is used, a flap of the posterior wall is attached to the posterior border of the soft palate. The flap consists of mucosa and the superior pharyngeal constrictor muscle. The muscle stays attached to the pharyngeal wall at the upper side (superior flap) or at the lower side (inferior flap). [19]
A common method to treat Velopharyngeal insufficiency is pharyngeal flap surgery, where tissue from the back of the mouth is used to close part of the gap. Other ways of treating velopharyngeal insufficiency is by placing a posterior nasopharyngeal wall implant (commonly cartilage or collagen) or type of soft palate lengthening procedure (i.e ...
Pharyngeal Flap Surgery. The superiorly based or inferiorly based pharyngeal flap surgical procedure offers an alternative to the fabrication of a palatal lift prosthesis. A pharyngeal flap surgery unites the posterior pharyngeal wall and the soft palate to definitively occlude the midsagittal aspect of the palatopharyngeal port while ...
The first involves surgery of the soft tissue (tonsillectomy, uvulopalatopharyngoplasty) and the second involves skeletal surgeries (maxillomandibular advancement). First, Phase 1 or soft tissue surgery is performed and after re-testing with a new sleep study, if there is residual sleep apnea, then Phase 2 surgery would consist of jaw surgery.
It results from "the approximation but inadequate closure of the upper border of the velum and the posterior pharyngeal wall." [ 1 ] To produce a velopharyngeal fricative, the soft palate approaches the pharyngeal wall and narrows the velopharyngeal port , such that the restricted port creates fricative turbulence in air forced through it into ...
