Velopharyngeal insufficiency is the inability to close the velopharyngeal port during speech and swallowing, leading to hypernasal speech and food regurgitation.

This study aimed to explore the aetiological factors contributing to the development of velopharyngeal insufficiency in a non-cleft paediatric population, especially following adenoidectomy.

A retrospective case review was conducted of all children without a known cleft palate, born between 2000 and 2013, who were referred to a tertiary cleft centre with possible velopharyngeal insufficiency.

The data for 139 children diagnosed with velopharyngeal insufficiency following referral to the cleft centre were analysed. Thirteen patients developed the condition following adenoidectomy; only 3 of these 13 had a contributing aetiological factor.

Velopharyngeal insufficiency is a rare but significant complication of adenoidectomy. The majority of patients who developed velopharyngeal insufficiency following adenoidectomy did not have an identifiable predisposing factor. This has important implications for the consent process and when planning adenoidectomy.

Acellular dermal matrices are increasingly used in laryngotracheal and pharyngeal reconstruction, but specific indications and the type of acellular dermal matrix used vary. The authors systematically reviewed outcomes relating to acellular dermal matrix use in head and neck reconstruction.

Electronic databases were searched through 1 May 2016 for literature on acellular dermal matrix use in laryngotracheal and pharyngeal reconstruction. Studies were appraised for surgical indications, outcomes and study design.

Eleven publications with 170 cases were included. Eight articles reported on acellular dermal matrix use in oncological reconstruction. Most studies were case series; no high-level evidence studies were identified. Graft extrusion was more common in non-oncological applications. In general, post-oncological reconstruction with an acellular dermal matrix demonstrated complication rates similar to those reported without an acellular dermal matrix.

Evidence in support of acellular dermal matrix use in head and neck reconstruction is generally poor. Prospective comparative studies are required to define the indications, safety and effectiveness of acellular dermal matrices in laryngotracheal and pharyngeal reconstruction.

To assess the role of video endoscopy in evaluating velopharyngeal incompetence and investigate a possible relationship between velopharyngeal incompetence type and speech defect in cleft palate patients.

A prospective study of 28 pre- or post-operative cleft palate patients with speech defects who attended Plastic Surgery–Cleft Palate and ENT out-patient clinics was performed. The velar defect type was determined using a flexible endoscope and findings were video recorded. Speech pathology was assessed using the cleft palate audit protocol for speech.

A significant, clinically relevant relationship was noted between the perceived characteristics of hypernasality and velopharyngeal insufficiency type. Hypernasal speech was a definite clinical indicator of velopharyngeal incompetence, and the type 1 velopharyngeal defect was most common. Type 1 velopharyngeal coronal-type dysfunction was strongly associated with hypernasality (p < 0.05). When speech substitution was noted, type 2 velopharyngeal (or sagittal) incompetence could be predicted (p < 0.05).

In the management of cleft palate patients, it is important that surgical correction of the defect and achieving velopharyngeal competency for speech are performed simultaneously. Pre-operative velopharyngeal endoscopy with speech assessment will define the anatomical and functional bases for velopharyngeal correction and assist in planning and tailoring the pharyngeal flap.
