Results with Furlow palatoplasty in management of velopharyngeal insufficiency

A retrospective study was undertaken to assess speech outcomes in patients undergoing Furlow palatoplasty. Since 1994, the authors have used the position of the levator veli palatini musculature to determine type of surgical intervention recommended for the management of velopharyngeal insufficiency. Furlow palatoplasty has been used in patients with clinical evidence of sagittally oriented levator veli palatini musculature. Forty-eight patients who underwent a Furlow palatoplasty between June of 1994 and August of 1998 were included. All patients underwent preoperative and postoperative perceptual speech analyses to describe velopharyngeal insufficiency severity, nasal air emissions, and resonance, and preoperative nasendoscopy to assess velopharyngeal gap size and palatal and lateral pharyngeal wall movement. Other patient characteristics considered included gender, age at time of surgery, previously repaired cleft palate, submucous cleft palate, and syndrome diagnosis. Speech outcomes were determined on the basis of postoperative perceptual speech analyses and were categorized in one of three ways: (1) complete resolution of velopharyngeal insufficiency, (2) substantial improvement of velopharyngeal insufficiency, and (3) audible residual velopharyngeal insufficiency. Complete resolution of velopharyngeal insufficiency was defined as normal resonance and an absence of nasal air emissions. Substantial improvement of velopharyngeal insufficiency was defined as an improvement of at least two categories in velopharyngeal insufficiency severity in those patients without complete resolution. Audible residual velopharyngeal insufficiency refers to patients with postoperative velopharyngeal insufficiency severity ratings of mild, moderate, or severe. The male:female ratio in the study was 27:21. Twelve patients were syndromic; three had velocardiofacial syndrome. The median age at surgery was 6.5 years (range, 2 to 22 years). The average duration of follow-up was 14.7 months (range, 1.3 to 58.6 months). Postoperatively, the severity of velopharyngeal insufficiency was rated as none in 19 of the 48 patients (39.6 percent), minimal in eight (16.7 percent), mild in six (12.5 percent), moderate in nine (18.75 percent), and severe in six (12.5 percent). Substantial improvement was seen in seven of the 29 patients without complete resolution. There was a significant association between male gender and complete resolution of velopharyngeal insufficiency (p < 0.05). Presence of syndrome and female gender was associated with audible residual velopharyngeal insufficiency (p < 0.05). The main complication was palatal fistula (two cases). In conclusion, most patients who underwent a Furlow palatoplasty had a complete resolution or substantial improvement of velopharyngeal insufficiency postoperatively, and there were few surgical complications.

[Functional results of velopharyngoplasty: apropos of 55 cases]

From 1991 until 1998, 55 three to twelve year-old patients underwent a velopharyngoplasty to correct velopharyngeal insufficiency. They had indeed severe hypernasality with or without gross reflux of food matter into the nasal cavities or behavioural disturbances. Eighty-two percent had a closed cleft palate. Forty percent presented with mental retardation, heart diseases or multiple syndromal defects. They all had had a previous speech therapy for a long (months) or a very long (years) period of time. In the post operative period, hypernasality disappeared totally or partially in eighty-five percent; reflux disappeared in almost all cases. Middle ear pathologies were not more frequent and were also less severe. Behavioral disturbances associated with a severe speech defect were also less pronounced.

Association between velopharyngeal function and dental-consonant misarticulations in children with cleft lip/palate

We studied the association between velopharyngeal function and misarticulation of the dental consonants /r/, /s/ and /l/ in children with cleft lip/palate. We assessed 278 6-year-old Finnish-speaking non-syndromic children (115 girls, 163 boys) with isolated cleft palate (n= 81), cleft lip/alveolus (n= 82) or unilateral (n= 84) or bilateral (n= 31) cleft lip and palate. Auditory analysis of speech and velopharyngeal function, the presence of fistulae, previous velopharyngoplasty and speech therapy, as well as surgical technique and timing of primary palatal surgery were obtained from the hospital records. The misarticulations of the sounds /r/, /s/ and /l/ were evaluated in spontaneous speech by two experienced speech pathologists from the cleft team. Velopharyngeal function was categorised, on the basis of the effect on speech, into competent, marginal incompetent and obvious incompetent. Nasal grimace and distortions due to palatal fistulae were registered. The results indicated that velopharyngeal function was not significantly associated with misarticulation of any of the sounds /r/, /s/ and /l/ or their combinations in any cleft groups. The technique and timing of primary palatal surgery, the presence of fistulae and previous pharyngoplasty were not associated with misarticulations. On the basis of these results we conclude that dental-consonant misarticulations occur independently of velopharyngeal function, primary palatal surgical technique and timing of palatoplasty.

Uvulopalatopharyngoplasty, maxillomandibular advancement, and the velopharynx

OBJECTIVE

To evaluate the presence of velopharyngeal insufficiency (VPI) symptoms and the associated changes of the velopharyngeal anatomy in patients who underwent maxillomandibular advancement (MMA) for persistent obstructive sleep apnea (OSA) after uvulopalatopharyngoplasty (UPPP).

METHODS

Preoperative and postoperative cephalometric radiographs were analyzed to assess the anatomic changes of the velopharynx. In addition, a questionnaire survey was sent to the patients between 6 to 12 months after MMA. The questionnaires evaluated the presence and extent of VPI symptoms, including nasal regurgitation while eating or drinking as well as hypernasal speech. A 10-cm visual analog scale (VAS 0-10) was included to assess the impact of VPI symptoms on the patient's quality of life. In the patients who reported VPI symptoms, telephone interviews were conducted 1 year after the survey to evaluate the changes in VPI symptoms over time.

RESULTS

Fifty-two of the 65 questionnaires were returned. Five patients (9.6%) reported nasal regurgitation of liquids when drinking hastily, with 2 patients reporting the occurrences as occasional and 3 patients reporting as rare. The impact of these symptoms on the patient's quality of life was minimal (VAS 0.6 +/- 0.4). Regurgitation of food or hypernasal speech was not reported. The telephone interviews 1 year later revealed that the symptoms have completely resolved in all 5 patients. Comparison of the preoperative and postoperative cephalometric radiographs demonstrated the pharyngeal depth increase was 48% of the amount of maxillary advancement and the functional pharyngeal length increased 53% of the maxillary advancement. The functional depth of the pharynx after MMA was significantly greater in the patients with VPI symptoms (P=.01).

CONCLUSION

The results of this study suggest that patients who undergo MMA for persistent OSA after UPPP have a low risk of developing VPI. If symptoms occur postoperatively, they are mild and have minimal effect on the patient's quality of life; moreover, the symptoms usually resolve over time.

Levatorplasty, a new technique to treat hypernasality: anatomical investigations and preliminary clinical results

BACKGROUND

Velopharyngoplasty is the most commonly used operative technique for the treatment of velopharyngeal insufficiency. By attaching a posterior pharyngeal flap to the velum, a nonphysiological situation is created in the upper airway.

PURPOSE

The aim of this investigation was to find a new surgical approach to physiological reconstruction of the velopharyngeal sphincter.

MATERIAL

Anatomical investigations were performed in four cadavers. From this study a new surgical technique was developed and called 'levatorplasty': the musculus longus capitis was taken to create a new muscular loop leading to (a) an augmentation of the posterior wall, (b) a medial shift of the lateral pharyngeal wall; and (c) stretching of the velum posteriorly. Thus, the velopharyngeal space was reduced and a physiological closure of the nasal airway space could be obtained.

STUDY DESIGN

The levatorplasty was employed in nine cleft palate patients with velopharyngeal insufficiency. Pre- and postoperatively the velopharyngeal closure was evaluated by phonetic and radiological examination.

RESULTS

The operation was easily performed without major complications. A concentric constriction with decrease of the velopharyngeal space was achieved and a definitive decrease of nasalance and hypernasality resulted.

CONCLUSION

Long-term follow-ups have to verify whether these results will be stable. They also have to be compared with functional improvements following velopharyngoplasty or pharyngoplasty. Of special interest will be evaluation of the altered mobility of the lateral pharyngeal walls.

[Modified uvula flap in therapy of sleep-related breathing disorders]

BACKGROUND/OBJECTIVE

Velopharyngeal incompetence is a well described complication of uvulopalatopharyngoplasty (UPPP) for snoring or obstructive sleep apnea. A new uvulopalatal flap technique (UPF), first presented by Powell in 1996 was now modified by our team. The new technique intends to lateralize the posterior faucial pillars as the UPPP, entirely sparing uvulopalatal muscles.

RESULTS

No statistical difference existed in change of AHI before and after surgery in all patients even though 14 patients had a statistically significant decrease in AHI (pre 19.2 +/- 19.6; after 8.2 +/- 9.8; p < 0.05). Snoring decreased clearly (p < 0.05) from 49.4% to 25.9%.

La maladie de Grisel: spontaneous atlantoaxial subluxation

OBJECTIVE

"La maladie de Grisel" (Grisel's syndrome) is a spontaneously occurring atlantoaxial subluxation with torticollis. We present a case of atlantoaxial subluxation occurring in a 20-year period of pharyngoplasty surgery. The occurrence of a "spontaneous" atlantoaxial subluxation after oral cavity or pharynx operations is rare. Because some neck pain and stiffness are commonly seen after these kinds of operations, we would like to draw attention to this unusual complication. Symptoms associated with a torticollis after an operation in the oral cavity or pharynx requires additional investigation to exclude this rare complication. A review of the available literature concerning etiology and treatment of la maladie de Grisel is presented.

Superiorly based flap pharyngoplasty: the degree of postoperative "tubing" and its effect on speech

It is recognised that superiorly based pharyngeal flaps tend to contract resulting in narrowing and lowering of the flaps. If lateral pharyngeal-wall motion is unable to close against the "tubed" flap or if the flap migrates below the level of medial displacement of the lateral pharyngeal walls, velopharyngeal insufficiency will result. The extent of this phenomenon of flap contracture or shrinkage has not been previously quantified. A consecutive series of 120 superior flap pharyngoplasty operations were assessed critically and carefully. The mean width of the harvested flap measured 89% of the width of the pharyngeal posterior wall and shrank over 6 months to 45% of the lateral pharyngeal diameter. The relations between speech results, complication rate and remaining flap width are analysed. All flaps shrink but to a varying degree.

Retropharyngeal autologous fat transplantation for congenital short palate: a nasometric assessment of functional results

Seventeen patients (4 to 24 years old; mean, 9.7 years) with mild velopharyngeal insufficiency were treated in our department during the period 1996 to 1999 with augmentation of the posterior pharyngeal wall with autologous fat. The main disorder was a congenital short palate without a cleft, in most cases revealed by adenoidectomy. Four patients had previously undergone pharyngoplasty, and 1 had already been injected in the posterior pharyngeal wall with Teflon paste. All patients had been exhaustively treated with speech therapy, and the result remained unsatisfactory. The functional outcome of the surgical procedure was quantified by acoustic nasometry. The decrease of the nasalance percentage for a standardized spoken passage was significant 1 to 3 months after the fat transplantation, and there was a slight tendency to further reduction of nasality at the late follow-up visit, more than 6 months (average, 9.4 months) after the intervention. The mean value of the nasalance score for the "normal passage" (running speech) then reached the limit of normal values. A long-term follow-up (average, 24.3 months) by telephone questionnaire confirmed the persistence of the beneficial results. Autologous fat seems an excellent alternative for Teflon in this indication. Acoustic nasometry allows a precise quantitative assessment of functional velopharyngeal surgery.

Furlow palatoplasty to restore velopharyngeal competence following tonsillectomy avulsion of a pharyngeal flap

OBJECTIVE

We report the successful use of a Furlow palatoplasty to salvage velopharyngeal competence following iatrogenic avulsion of a pharyngeal flap that had been previously established to treat velopharyngeal insufficiency associated with a submucous cleft palate.

INTERVENTION

A tonsillectomy, conducted by a surgeon unaffiliated with a cleft palate team, was used to remove enlarged tonsils that had developed after pharyngeal flap surgery and extended into the lateral ports causing nasal obstruction and hypernasality because of mechanical interference with port closure. A posttonsillectomy evaluation revealed avulsion of the pharyngeal flap, which was successfully treated using a Furlow palatoplasty.

CONCLUSIONS

To our knowledge, this is the first report of iatrogenic avulsion of a pharyngeal flap caused by tonsillectomy. Based on a review of the literature and this case experience, we would conclude that tonsillectomy should not be regarded as a routine procedure in patients previously treated with a pharyngeal flap. If required, it should be performed by a skilled otolaryngologist, preferably one affiliated with a multidisciplinary cleft palate team who is familiar with pharyngoplasty surgery. Finally, our experience would suggest that the Furlow palatoplasty is sufficiently robust to be used as a secondary salvage procedure to restore velopharyngeal sufficiency following iatrogenic avulsion of a pharyngeal flap.

Surgical treatment of submucous cleft palate: a comparative trial of two modalities for palatal closure

Submucous cleft palate is a congenital malformation with specific clinical and anatomical features. It can be present with or without velopharyngeal insufficiency. Surgical treatment of this malformation is indicated only when velopharyngeal insufficiency has been demonstrated. This article compares two modalities of surgical treatment for submucous cleft palate. The first includes a minimal incision palatopharyngoplasty, as described in a previous report. The second combines the first technique with additional individualized velopharyngeal surgery (individualized pharyngeal flap or sphincter pharyngoplasty) performed simultaneously. The individualized part of the procedure was selected and performed according to the findings of videonasopharyngoscopy and multiview videofluoroscopy, as reported previously. Two hundred and three patients with submucous cleft palate were studied from 1990 to 1999. Videonasopharyngoscopy and multiview videofluoroscopy demonstrated velopharyngeal insufficiency in 72 patients, who were randomly divided into two groups. Those in group 1 (n = 37) underwent a minimal incision palatopharyngoplasty. Patients in group 2 (n = 35) also underwent that procedure but simultaneously received individualized pharyngeal flap or sphincter pharyngoplasty, according to the findings of videonasopharyngoscopy and multiview videofluoroscopy. The median age of the patients from both groups was not significantly different (p > 0.5). The frequency of residual velopharyngeal insufficiency after palatal closure was not significantly different in both groups of patients (14 percent versus 11 percent; p > 0.5). The mean size of the gap at the velopharyngeal sphincter during speech was not significantly different in both groups of patients before surgery (23 percent versus 22 percent; p > 0.5). After the surgical procedures, there was a nonsignificant difference between both groups of patients in mean residual size of the gap in cases of velopharyngeal insufficiency (7 percent versus 8 percent; p > 0.5). It seems that minimal incision palatopharyngoplasty is a safe and reliable procedure for palatal closure in patients with submucous cleft palate. The use of additional individualized velopharyngeal surgery performed simultaneously did not seem to decrease the frequency of residual velopharyngeal insufficiency. Moreover, the residual size of the gap at the velopharyngeal sphincter was not significantly reduced when an additional surgical procedure was performed simultaneously with palatal closure.

Cleft lip and palate care in the United Kingdom--the Clinical Standards Advisory Group (CSAG) Study. Part 3: speech outcomes

OBJECTIVE

To summarize speech outcomes in children born with unilateral cleft lip and palate (UCLP) throughout the United Kingdom.

DESIGN

Prospective descriptive study on a cross-sectional sample of children.

PATIENTS/PARTICIPANTS

Data were collected for 238 5-year-olds (born between April 1, 1989, and March 31, 1991) and 218 12-year-olds (born between April 1, 1982, and March 31, 1984) with complete UCLP.

MAIN OUTCOMES

Ratings of intelligibility, nasality, "speech cleft type characteristics" and speech therapy intervention.

CONCLUSIONS

Nineteen percent of 5-year-olds and 4% of 12-year-olds were judged to be impossible to understand or just intelligible to strangers. Thirty-four percent of 5-year-olds and 17% of 12-year-olds had at least one serious error of consonant production. Eighteen percent of 5-year-olds and 12-year-olds had consistent hypernasality of mild, moderate, or severe degree. Approximately two-thirds of both age groups had undergone speech therapy.

Approaches to cleft lip and palate repair

Facial clefts remain one of the most common congenital anomalies encountered by plastic surgeons. Over the last few decades, surgical results have continued to improve due to the interdisciplinary approach to this complex clinical problem.

Radiographic and aerodynamic measures of velopharyngeal anatomy and function following Furlow Z-plasty

Recent studies have shown that the Furlow double-opposing Z-plasty has several advantages that make it an attractive procedure for cleft palate repair and treatment of velopharyngeal insufficiency in selected cases. The anatomic changes associated with this procedure have never been documented prospectively. The purpose of this study was to describe radiographic dimensions of the velopharynx and aerodynamic measures of velopharyngeal function in a group of patients before and after Furlow Z-plasty for the treatment of velopharyngeal insufficiency. Twelve consecutive patients with cleft palate and velopharyngeal insufficiency, ranging in age from 3 to 19 years, were selected as candidates for Furlow Z-plasty based on perceptual, endoscopic, and radiographic findings. Eight patients had repaired cleft palate with a residual muscle diastasis and four patients had unrepaired submucous cleft palate. Subjects received aerodynamic and cephalometric assessments before and after Z-plasty. Cephalometric x-rays were measured for velar length, thickness, and pharyngeal depth. Mean nasal airflow during pressure consonants (Vn) was calculated from pressure/flow studies, and patients were categorized as having complete closure (<10 cc/sec Vn) or incomplete closure (>10 cc/ sec Vn). After Z-plasty, there was a significant increase in velar length (p = 0.002) and velar thickness (p = 0.001). After surgery, patients with complete velopharyngeal closure had significantly greater velar length than the incomplete closure group (p = 0.05) with nearly twice the increase in length. Similarly, following surgery, the complete closure group had significantly greater thickness than the incomplete closure group (p = 0.01), with a greater postoperative increase in velar thickness (p = 0.005). Finally, there was a significant negative correlation between percent increase in length and percent increase in thickness for patients in the complete closure group (r = -0.91, p = 0.03). Findings demonstrate that following Furlow Z-plasty, patients with cleft palate and velopharyngeal insufficiency obtained significant increases in velar length and thickness. Greater velar length and greater velar thickness both were associated with complete velopharyngeal closure. Patients in the complete closure group tended to demonstrate large percent gains in either length or thickness or moderate gains in both. Patients in the incomplete closure group tended to demonstrate relatively small percent gains in both dimensions. Results suggest there may be important anatomic features (such as pharyngeal depth/velar length ratio) that can be evaluated before surgery to predict which patients may be most likely to benefit from Furlow Z-plasty as a form of treatment for velopharyngeal insufficiency.

Chiari malformation, cervical spine anomalies, and neurologic deficits in velocardiofacial syndrome

The purpose of this investigation was to evaluate the prevalence of Chiari malformation, cervical spine anomalies, and neurologic deficits in patients with velocardio-facial syndrome. This study was a prospective evaluation of 41 consecutive patients with velocardiofacial syndrome, documented by fluorescence in situ hybridization, between March of 1994 and September of 1998. The 23 girls and 18 boys ranged in age from 0.5 to 15.2 years, with a mean age of 6.7 years. Nineteen patients were assessed with magnetic resonance imaging, 39 underwent lateral cephalometric radiography, and all patients were examined for neurologic deficits. Eight of 19 patients (42 percent) had anomalies of the craniovertebral junction, including Chiari type I malformations (n = 4), occipitalization of the atlas (n = 3), and narrowing of the foramen magnum (n = 1). One patient with Chiari malformation required suboccipital craniectomy with laminectomy and decompression. Fourteen of 41 patients (34 percent) had demonstrated neurologic deficits; 10 patients (24 percent) had velar paresis (6 unilateral and 4 bilateral). Chiari malformations, cervical spine anomalies, and neurologic deficits are common in velocardiofacial syndrome. Because these findings may influence the outcome of surgical intervention, routine assessment of patients with velocardiofacial syndrome should include careful orofacial examination, lateral cephalometric radiography, and magnetic resonance imaging of the craniovertebral junction.

Refinement of velopharyngoplasty in patients with cleft palate by covering the pharyngeal flap with nasal mucosa from the velum

The velopharyngoplasty performed using the popular Sanvenero-Rosselli method improves the speech quality of patients with cleft palate suffering from persistent velopharyngeal insufficiency despite successful closure of the hard and soft palates. However, often a relatively narrow pharyngeal bridge results due to healing not only by granulation and scar contraction, but also due to the insertion of the inferior tip of the flap into a narrow bed. Elevation of two velar flaps with nasal mucosa to cover the exposed muscular undersurface of the pharyngeal flap produces a broader recipient bed into which the pharyngeal flap can be spread. The speech quality of 27 patients treated with this modified method (group B) was compared with that of 27 patients without this modification (group A). Eight weeks after velopharyngoplasty (followed by uneventful wound healing) the speech quality of group B was significantly better than that of group A (p<0.03 MannWhitney U-test). This difference was even more evident when comparing the preoperative with the postoperative speech quality (p<0.005). Thus, covering the exposed muscular layer of the pharyngeal flap with nasal mucosa of the velum is an important modification of velopharyngoplasty for the improvement of speech quality.

[Speech improvement with velopharyngoplasty in patients with lip-jaw-palate clefts]

BACKGROUND

Despite successful closure of the hard and soft palate and intensive speech therapy a velopharyngeal insufficiency is not completely avoidable in each case of cleft palate. An improvement by velopharyngoplasty should be possible.

PATIENTS AND METHODS

Two hundred and ninety patients suffering from cleft palate were examined before and one year after velopharyngoplasty according to Sanvenero-Rosselli. Four main symptoms of the affected speech were assessed: changes of the resonance, inappropriate nasal air emission, articulary disorders (deviations from articulation areas), and non-physiological facial expression during speaking, each divided into three grades. Afterwards, the complete speech quality was classified.

RESULTS

Assessing the symptoms separately and summarised the therapy including velopharyngoplasty was suitable to improve the speech quality in 83.1% of the cases, resulting in a widely unaffected speech. The improvement was greater in younger patients undergoing operation (Gamma-test, p < 0.001). But the final results were independent from age due to poorer initial situation in younger patients (Gamma-test, p < 0.001).

CONCLUSIONS

The velopharyngoplasty is an important method for repair of velopharyngeal insufficiency in patients with cleft palate. In each individual case it is necessary to consider carefully if and when this operation should be performed. An intensive interdisciplinary co-operation of all specialists involved in the treatment is indispensable.

Does MRI contribute to the investigation of palatal function?

The results of a pilot study into the value of MRI scanning in investigation of velopharyngeal function are discussed. MRI offers potential advantage over naso-endoscopy in being noninvasive and over video fluoroscopy in avoiding radiation. However, it requires costly equipment and patient cooperation, which limits its use in young patients. Ten normal volunteers and 15 patients with speech problems underwent MRI of the velopharyngeal port at rest and during sustained phonation of word /a/. Optimal planes for scanning were determined. Images were obtained in mid-sagittal, coronal and horizontal planes at the level of the hard palate and in the plane of the levator axis. Computer assisted measurements were possible of the velopharyngeal closure, forward movement of posterior pharyngeal wall, velar lift, velar extensibility and medial movement of the lateral pharyngeal wall. MRI has a potential role in investigation of velopharyngeal incompetence and planning its surgical repair.

Palatal distraction in a canine cleft palate model

The purpose of this study was to determine whether the canine hard palate can be lengthened by distraction osteogenesis in a cleft palate model using a mostly submucosal distractor. Five mongrel dogs were used. After raising mucoperiosteal flaps, a midline strip of bone was removed from the hard palate of each dog to simulate the bony defect seen in a cleft palate. A transverse osteotomy was then made to separate the posterior segment of the hard palate from the anterior segment. Posterior osteotomies were also made laterally parallel to the teeth so that the 2 posterior segments (one on either side of the bony cleft) were mobile. An intraoral distractor that was mostly submucosal was attached to the anterior hard palate and both segments of the mobilized posterior hard palate. Radiopaque bone markers were placed, and x-rays were obtained. After a 10-day latency period, the distractor was expanded 0.675 mm per day until it had been lengthened 10.125 mm. Distractors were left in place for an additional 8 weeks. After distractor removal, animals were observed for an additional 8 weeks before euthanization. Follow-up x-rays and histologic examinations were performed. New bone formation was found at the site of distraction in all dogs at the time of death. This new bone was seen on the follow-up x-rays and on histologic examination of the hard palates using both hematoxylin and eosin staining and Masson's trichrome stain. Distraction osteogenesis using a mostly submucosal device is an effective technique for lengthening the hard palate in a canine cleft palate model. The technique may eventually provide an alternative treatment for velopharyngeal incompetence in humans that is more precise and involves less morbidity than existing treatments.

Side effects after surgical treatment of snoring

In a questionnaire study detailed side effects after snoring surgery were examined in 415 individuals 2-8 years after surgery. Three years later a new questionnaire was answered by those with side effects affecting taste, smell and voice (n = 74). At the first follow-up 255 had side effects of globus, regurgitation, taste, smell and voice. The globus was the most common (40%). In all spheres except the globus, a significant improvement was seen 3 years later. However, pharyngeal dryness and phlegm had a reported frequency of nearly 60%. No significant differences were seen between the uvulopalatopharyngoplasty and laser uvulopalatoplasty methods. Taste disturbances might be due to surgical damage to the nerves or oral dryness. The olfactory impairment present in 7 patients still needs to be explained.
